Terms of Service

These Terms of Service form a legal agreement between you and 0x234 Pty Ltd, the operator of DoubleTime.

By creating an account, subscribing to the service, accessing the website or application, using the API, authorising an application, using MCP or AI tool access, viewing hosted invoice content or otherwise using DoubleTime, you agree to these Terms. If you do not agree to these Terms, you must not use the service.

Some sections apply only to account holders, subscribers or users of particular features.

1. Introduction and Acceptance

These Terms govern your access to and use of DoubleTime. They apply to the website, application, API, OAuth authorisation features, MCP server access, hosted invoice pages, support channels and related services that we provide.

You are responsible for your use of your account, credentials, hosted invoice links and service communications, including how you share them and any access you authorise through them.

2. Who We Are and Scope of these Terms

DoubleTime is operated by 0x234 Pty Ltd, an Australian proprietary limited company. In these Terms, "DoubleTime", "we", "us" and "our" refer to 0x234 Pty Ltd.

These Terms apply to users who create accounts, subscribe to paid features, use free or trial features, access hosted invoice content, interact with invoice communications, use the API, register or authorise OAuth applications, use MCP or AI tool access, submit support requests or otherwise use the service.

Additional terms, feature descriptions or checkout terms may apply to particular plans, integrations, trials or features. If additional terms conflict with these Terms, the more specific terms apply to the extent of the conflict.

We operate DoubleTime from Australia and make the service available for business and professional use. The service may be accessed from outside Australia, but we do not represent that the service is appropriate, compliant or available for use in every country.

You are responsible for complying with any laws that apply to your use of the service, including laws relating to invoicing, tax, record keeping, privacy, electronic communications, spam, consumer protection and business conduct. Information about where personal information is stored and processed is set out in our Privacy Policy.

3. Key Terms

In these Terms:

"Account" means a unique account created for you to access the service or parts of the service.
"API token" or "service API token" means a credential issued from an account that allows programmatic access to the service on the account holder's behalf, without requiring their login credentials.
"Connected app" means an OAuth application or integration that you authorise to access your account, account data or service features.
"Content" or "User Content" means any information, data, text, files, attachments, notes, invoices, payment instructions, client, customer or recipient information, business information, time records, project records or other material that you submit, upload, generate, store, send or make available through the service.
"Hosted invoice link" means a URL-based method of invoice delivery where an invoice is made available through a web page served by the service, rather than as a file attachment.
"Invoice credit" means an allowance granted under a free or non-subscriber plan which may be consumed when an invoice is finalised or otherwise converted into a ready-to-use invoice, as described in the service.
"Invoice recipient" means a person or entity to whom an invoice, payment receipt, hosted invoice link, attachment, reminder or related communication is sent or made available through the service.
"MCP client" or "AI tool" means an application, assistant, agent or other tool that connects to the DoubleTime MCP server or uses MCP-compatible access to work with DoubleTime data or actions.
"OAuth application" means an application, integration or MCP-compatible client that uses DoubleTime's OAuth authorisation features to request scoped access to the service.
"OAuth grant" means your approval for a connected app to access selected service resources and scopes.
"Payment instructions" means details you choose to display on invoices to allow clients, customers or recipients to pay you directly, such as bank account details, PayID information or other payment directions.
"Personal information" means information or an opinion about an identified individual or an individual who is reasonably identifiable. Some jurisdictions refer to similar information as "personal data".
"Protected access flow" means a hosted invoice link flow that requires a recipient to verify their email address before the invoice can be viewed.
"Scope" means a permission category that limits the account data, service resources or actions an OAuth application, connected app, MCP client or AI tool may request.
"Service" means DoubleTime, including our website, application, API, OAuth authorisation features, MCP server access, hosted invoice pages, infrastructure, support channels, communications and related services.
"Standard link-based access" means a hosted invoice link that does not require recipient verification, meaning anyone in possession of the link may be able to view the invoice.
"Subscription" means a paid plan that grants access to paid features of the service.
"Third-party API token" means a credential issued by a third-party provider that you supply to the service so it can access an external account or service in connection with an import, migration or integration.
"Third-party login provider" means a third-party authentication provider through which you can log in to, create or link an account for the service.
"User" means any person or entity accessing or using the service, including account holders, subscribers, invoice recipients, visitors, API users, connected-app users, MCP clients and AI tools. Some terms apply differently depending on how the service is used.
"You" and "your" refer to the person or entity accessing or using the service.

4. Eligibility and Business Use

You may create an account or use DoubleTime only if you are at least 18 years old, are legally able to enter into a binding agreement and are using the service for business or professional purposes.

If you create an account or use the service on behalf of a business, company, sole trader operation, partnership, client- or customer-facing practice or other commercial activity, you represent that you are authorised to do so and to provide the business information, client or customer information, invoice information, payment instructions and other content entered into the service.

You must provide current, complete and accurate information when using the service and keep your account and business information up to date.

5. Account Registration and Account Security

You are responsible for maintaining the confidentiality and security of your account, login credentials, sessions, API tokens, OAuth applications, connected apps, MCP clients and devices used to access the service. You are responsible for activity that occurs through your account, except to the extent caused by our breach of these Terms or applicable law.

You must notify us promptly if you become aware of unauthorised access to your account, credentials, API tokens, OAuth applications, connected apps, MCP clients or hosted invoice links.

You may be able to log in using a third-party login provider. You are responsible for maintaining access to and security of the third-party account you use for authentication.

We use information returned by the login provider to authenticate, create or link your DoubleTime account. Temporary authentication tokens used for login are not used to maintain ongoing access to the login provider account, unless a separate integration or feature expressly requires and describes that access.

If a third-party login provider becomes unavailable, changes its service or terminates your access, your ability to log in to DoubleTime through that provider may be affected.

5.2 Service API Tokens

Service API tokens may provide broad access to your account through the API. Unless a token is expressly described as limited or scoped, you should treat it as capable of performing actions available to your account.

You are responsible for creating, storing, rotating, revoking and protecting service API tokens. Do not share API tokens with any person or system unless you are comfortable granting that person or system access to your account.

We may expire, revoke, restrict or disable API tokens where required for security, legal, operational or abuse-prevention reasons.

5.3 OAuth Applications, Connected Apps and MCP/AI Tool Access

OAuth applications, connected apps, MCP clients and AI tools may request scoped access to your account. If you approve access, the application or tool may read, create, update, delete, send or financially affect records depending on the scopes and access targets you grant.

You are responsible for deciding whether to trust an OAuth application, connected app, MCP client or AI tool before granting access. You should review the requested scopes, the application identity, the relevant third-party terms and privacy policy, and whether the requested access is appropriate for your business.

You may revoke connected-app access where the service provides that control. Revocation stops future access by that connected app, but it does not delete or retrieve information already received by the app, MCP client or AI tool before revocation.

If you register an OAuth application or developer client, you are responsible for using an accurate application name, configuring redirect URIs correctly, protecting client secrets, requesting only appropriate scopes, complying with applicable laws and third-party terms, and not misleading users about what the application can do.

We may expire, revoke, restrict, disable or delete OAuth clients, OAuth grants, tokens, MCP access or connected-app access where required for security, legal, operational, abuse-prevention or service-integrity reasons.

6. Licence to Use the Service

Subject to these Terms, we grant you a limited, non-exclusive, non-transferable and revocable licence to access and use the service for your own business or professional purposes.

This licence does not give you ownership of the service, our software, our brand, our website, our application, our infrastructure or any intellectual property rights in those materials.

7. Your Content, Business Data and Client/Customer/Recipient Data

You retain ownership of your content. We do not claim ownership of the business information, client, customer or recipient information, invoice information, time records, attachments, payment instructions or other content you provide to the service.

You grant us a worldwide, non-exclusive, royalty-free licence to host, store, reproduce, process, transmit, display, make available to connected apps you authorise and otherwise use your content solely as necessary to provide, operate, secure, support, improve and maintain the service, comply with these Terms and comply with applicable law.

You represent that you have all rights, permissions, notices, consents and lawful bases required to provide your content to us and to use it through the service, including any client, customer, recipient, business contact, invoice, payment instruction, attachment or imported data.

You are responsible for the accuracy, legality and suitability of your content and for ensuring that your use of the service complies with laws that apply to your business.

8. Invoicing Features, Hosted Invoice Links and Attachments

DoubleTime provides time tracking, invoicing, billing workflow and related productivity features. The service is not an accounting suite, tax adviser, debt collection service, payment processor for your client or customer invoices or substitute for professional financial advice.

You are responsible for reviewing invoices, amounts, tax treatment, payment records, client or customer information, attachments, payment instructions and communications before sending, finalising or relying on them.

8.1 Free and Non-Subscriber Invoicing

Free and non-subscriber features may include a limited number of invoice credits. An invoice credit may be consumed when a draft invoice is finalised or otherwise converted into a ready-to-use invoice, as described in the service.

We may change the number, timing, availability or conditions of free invoice credits, subject to applicable law and any specific commitments made in the service.

8.2 Billing Hub, Billing Recovery and Guided Drafts

Billing Hub and related billing recovery features may identify time entries, projects, tasks or work for clients or customers that appear potentially billable, unbilled, overdue or suitable for a draft invoice.

These features are workflow aids only. They may be incomplete, delayed or incorrect, and they may not identify every billable item, non-billable item, prior payment, contractual arrangement, credit, write-off, tax treatment or accounting adjustment relevant to your business.

You remain responsible for reviewing guided drafts, invoice suggestions, overdue invoice lists, billing recovery prompts and related calculations before issuing an invoice, contacting a client or customer, recording a payment or making business decisions.

8.3 Invoice Delivery, Public Links and Attachments

The service may allow you to send invoices, payment receipts, hosted invoice links, reminders and related communications to invoice recipients. You are responsible for ensuring recipient details are correct and that you are authorised to contact each recipient.

Email delivery is not guaranteed. An invoice, payment receipt, reminder or related communication may be blocked, delayed, filtered, rejected, misdirected or otherwise fail to be received due to incorrect recipient details, spam filters, recipient mail systems, third-party email providers, internet failures or other factors outside our control.

A record that the service attempted to send, queued or sent a communication does not mean the recipient received, opened or reviewed it. You are responsible for confirming delivery where it matters to your business.

A protected access flow requires a recipient to verify their email address before viewing the invoice. It is designed to reduce unintended access, but it is not a guarantee that every recipient device, email account or downstream copy is secure. A standard link-based access flow does not require recipient verification, meaning anyone with the link may be able to view the invoice.

You should avoid including sensitive client, customer or recipient information in unrestricted public invoice links unless you are comfortable making that information available to anyone with the link.

Attachments and files made available through hosted invoice links or invoice communications are your responsibility. You must not upload or send files that are unlawful, misleading, harmful, confidential without authority or infringe another person's rights.

8.4 Payment Instructions and Client/Customer Payments

The service may allow you to display payment instructions on invoices, including bank account details, PayID details or other payment directions. You are responsible for ensuring those details are accurate, current and suitable for the relevant invoice.

DoubleTime does not collect payment from your clients or customers on your behalf unless a specific feature expressly states otherwise. Payments made by your clients or customers are between you and the client, customer or recipient.

Where invoice card payments are available, a recipient may be directed to a Stripe-hosted checkout flow connected to your Stripe account. Stripe is responsible for processing payment details in accordance with its own terms and privacy policy. We may record checkout session details, payment attempt status and payment metadata so the service can display payment status and support reconciliation.

If payment instructions change, you are responsible for considering whether historical invoices, hosted invoice links, PDFs, communications or recipients need to be updated or notified.

8.5 Invoice Status, Payment Collection and Reconciliation

Invoice statuses, overdue indicators, payment records, reconciliation prompts, payment receipts and related reporting are provided to help you manage your workflow. They may not reflect actual payment, settlement, bank reconciliation, tax treatment or client or customer agreement unless you have accurately recorded and verified the relevant information.

You are responsible for confirming whether invoices have been paid, partially paid, written off, credited, disputed, cancelled or otherwise resolved. You are also responsible for keeping records required by your accountant, tax adviser, client or customer agreements and applicable law.

9. Subscriptions, Fees, Taxes and Payments

Some features require a subscription or payment. Plan availability, prices, inclusions, limits, billing intervals and feature access may vary and are shown in the service or at checkout.

We may change plans, prices, inclusions or feature limits from time to time. Unless stated otherwise, changes to subscription fees apply from your next billing cycle or when you next change your plan.

9.1 Evaluation Period / Free Trial

We may offer evaluation periods or free trials. Trial duration, eligibility, feature access, payment-method requirements and conversion terms are shown in the service or at checkout.

If a no-payment-detail trial is offered, you will not be charged unless you later provide a valid payment method and subscribe. If checkout or a payment method is required for a trial, the relevant terms will be shown before you start the trial.

We may limit, withdraw or change trial availability for operational, abuse-prevention or business reasons.

9.2 Payment Authorisation

Subscriptions are billed in advance on a recurring basis unless cancelled before the next billing cycle. By subscribing, you authorise Stripe to charge your selected payment method for the applicable subscription fees, taxes and other amounts shown at checkout.

For payment or subscription checkout, you may be redirected to a Stripe-hosted checkout page. For subscription and billing management, you may be redirected to Stripe's customer portal. Stripe is responsible for processing payment details in accordance with its own terms and privacy policy.

Unless stated otherwise, subscription fees are non-refundable except where required by law, where expressly stated in these Terms, or where we choose to issue a refund or credit at our discretion.

9.3 Taxes

Subscription fees may include or exclude taxes depending on your location, checkout flow and applicable law. Stripe may calculate, collect or display taxes at checkout where configured.

You are responsible for any taxes, duties, charges, reporting obligations or withholding obligations that apply to your use of the service or your business, except for taxes imposed on our income.

9.4 Recurring Payments and Cancellation

Your subscription renews automatically unless cancelled before the next billing cycle. You may manage or cancel your subscription through the service or Stripe's customer portal where available.

Cancelling a subscription stops future renewals but does not automatically refund fees already paid, except where required by law or expressly stated by us.

9.5 Non-Payment

If a payment fails, is reversed, is disputed or remains unpaid, we may retry the payment, suspend or downgrade paid features, restrict access to paid functionality, cancel your subscription or terminate access to the service.

You remain responsible for unpaid amounts that are lawfully due.

9.6 Payment Disputes

If you believe a subscription charge is incorrect, you should contact us promptly so we can investigate. Nothing in this section limits any rights you have under applicable law, card scheme rules or your payment provider's lawful dispute processes.

9.7 Access to Data After Subscription Ends

If your subscription ends, some paid features may become unavailable. We may allow you to view, export or delete certain account data, but access to creating, editing, finalising, sending, reporting on or otherwise using paid features may be restricted, including through API, OAuth, MCP or connected-app access.

You should export or retain copies of records that are important to your business before cancelling, downgrading or allowing a subscription to lapse.

10. Third-Party Services, Imports and Migration

The service may integrate with, import from or link to third-party services such as authentication providers, payment processors, time tracking tools, calendar providers, support tools, hosting providers, infrastructure providers, OAuth applications, MCP clients and AI tools.

If you provide a third-party API token, credentials or authorisation for an import, migration, OAuth application, MCP client, AI tool or other integration, you represent that you are authorised to do so. You are responsible for the third-party account, the accuracy of imported or shared data, and any terms or fees imposed by the third-party provider.

We are not responsible for third-party services, third-party content, third-party AI tool outputs, changes to third-party APIs, outages, rate limits, import errors, incomplete data, provider terms, provider decisions or downstream handling of data by third parties outside our reasonable control.

11. Service Communications and Notices

We may contact you by email or other electronic communication channels to provide service communications, including authentication messages, support responses, billing notices, legal notices, security alerts, invoice-related emails, payment receipts, reminders and account-critical notices.

You are responsible for ensuring your account email address and notification settings are accurate. Service communications may be required for the operation, security or legal administration of the service and may not be fully optional.

12. Service Changes, Availability and Discontinuance

We may update, modify, add, remove, suspend, limit or discontinue features from time to time. We may also perform maintenance, deploy changes, correct defects, address security issues or respond to operational needs.

We aim to provide a reliable service, but we do not guarantee that the service will be uninterrupted, error-free, available at all times, compatible with every device or browser, or free from delays, defects or outages.

If we discontinue the service generally, we will use reasonable efforts to provide notice and a reasonable opportunity to export available account data, where practicable and legally permitted. Refunds or credits for discontinued paid service will be provided where required by law, expressly offered by us or determined by us at our discretion.

13. Suspension, Termination and Account Deletion

You may stop using the service at any time. You may also request or initiate account deletion through the service where available.

If you request account deletion, your account may enter a grace period during which it can be restored. After the 7-day grace period, we will delete your account and associated user-generated data from active systems, subject to our Privacy Policy. Residual copies may remain in backups, logs, support records or records we are required or permitted to retain by law.

We may refuse, suspend, restrict or terminate access to the service where we reasonably believe that you have breached these Terms, failed to pay amounts owing, created security or legal risk, misused the service, infringed another person's rights, or used the service in a way that may harm us, other users, invoice recipients, third-party providers or the service.

We may also restrict, revoke or disable API tokens, OAuth applications, OAuth grants, MCP access, connected-app access or invoice links where reasonably necessary for security, legal, operational, abuse-prevention or service-integrity reasons.

Termination or suspension does not affect rights or obligations that arose before termination, including payment obligations, indemnities, limitations of liability and provisions intended to survive termination.

14. Intellectual Property and Feedback

We and our licensors own all rights, title and interest in the service, including the software, design, text, graphics, logos, trademarks, service marks, documentation, infrastructure, workflows and other materials we provide, excluding your content.

You must not copy, modify, adapt, translate, reverse engineer, decompile, disassemble, sell, rent, sublicense, distribute or create derivative works from the service except to the extent expressly permitted by these Terms or applicable law.

If you provide feedback, suggestions, ideas, feature requests or other recommendations, you grant us the right to use them without restriction or obligation to compensate you.

15. No Professional Advice and Financial Responsibility

DoubleTime is a time tracking and invoicing suite. It does not provide accounting, tax, legal, financial, payroll, bookkeeping, debt collection or professional advice.

You are responsible for reviewing and verifying invoices, calculations, tax treatment, reports, payment records, overdue status, payment instructions, client or customer communications, billing recovery suggestions and other financial records before relying on them.

You should obtain professional advice where appropriate. You remain responsible for ensuring that your business records, invoices, tax records, accounting records and client or customer communications are accurate and compliant with applicable law.

16. Privacy

Our handling of personal information is described in our Privacy Policy. By using the service, you acknowledge that we will handle personal information in accordance with that policy.

You are responsible for ensuring that you have the authority and lawful basis to provide client, customer, recipient, invoice, payment instruction and business contact information to us, to use that information through the service, and to authorise connected apps, MCP clients or AI tools to access that information.

17. Links to Other Websites

The service may contain links to third-party websites, services or resources that we do not own or control, including connected apps, MCP clients or AI tools that you authorise. We are not responsible for those third-party websites, services, resources, content, policies or practices.

You should review the terms and privacy policies of third-party services before using them.

18. Prohibited Use

You must not use the service to:

break the law or encourage unlawful conduct;
harass, threaten, abuse, mislead, defraud or impersonate any person;
send spam, unsolicited communications or communications you are not authorised to send;
upload, send or distribute malware, harmful files, malicious code or unsafe attachments;
attempt unauthorised access to the service, accounts, systems, networks or data;
conduct security testing, probing, scanning or vulnerability assessment without our prior written permission;
scrape, overload, interfere with, disrupt or place excessive automated requests on the service;
reverse engineer, bypass, disable or interfere with service protections, access controls or billing controls;
misrepresent an OAuth application, connected app, MCP client, AI tool or the permissions it requests;

infringe intellectual property, privacy, confidentiality or other rights;
create, send or publish misleading invoices, payment instructions, receipts or communications;
use the service to collect payments or information in a fraudulent, deceptive or unauthorised way; or
use the service in a way that may harm us, other users, invoice recipients, third-party providers or the service.

19. Disclaimers and Non-Excludable Rights

Nothing in these Terms excludes, restricts or modifies any guarantee, warranty, right or remedy that cannot be excluded, restricted or modified under applicable law, including the Australian Consumer Law where it applies.

Subject to those non-excludable rights, the service is provided on an "as is" and "as available" basis. We do not guarantee that the service will meet your requirements, be error-free, be uninterrupted, preserve all data, identify every billing issue, calculate every amount correctly or be suitable for your specific business, accounting, tax or legal needs.

We take reasonable steps to protect and maintain the service, but we do not guarantee that data will never be lost, corrupted, delayed, unavailable or unrecoverable. You are responsible for maintaining appropriate copies of records that are important to your business, including invoices, attachments, payment records, time records, tax records and client or customer communications.

Subject to the non-excludable rights in this section and to the maximum extent permitted by law, we are not responsible for loss, corruption or unavailability of data caused by factors outside our reasonable control, your acts or omissions, third-party services, internet or hosting failures, unauthorised access, or your failure to export or retain records needed for your business.

We do not guarantee the accuracy, reliability, suitability or compliance of third-party app outputs, AI tool outputs, agent actions, prompts, recommendations or automated workflows. You are responsible for reviewing actions and outputs before relying on them or sending communications through the service.

20. Limitation of Liability

Subject to the non-excludable rights section and to the maximum extent permitted by law, we are not liable for indirect, incidental, special, consequential, exemplary or punitive loss, loss of profit, loss of revenue, loss of goodwill, loss of opportunity, business interruption, loss of data, or loss arising from your reliance on invoices, calculations, reports, payment instructions, Billing Hub suggestions, connected apps, MCP clients, AI tools or other service outputs.

Subject to the non-excludable rights section and to the maximum extent permitted by law, our total liability to you arising out of or in connection with the service or these Terms is limited to the greater of the fees you paid to us for the service in the 12 months before the event giving rise to the claim, or USD $100.

21. Indemnity

To the maximum extent permitted by law, you indemnify us, our officers, employees, contractors and agents against losses, liabilities, claims, damages, costs and expenses arising from or connected with your content, your breach of these Terms, your misuse of the service, your invoices, payment instructions, client, customer or recipient communications, imports, API usage, OAuth applications, connected apps, MCP or AI tool access, breach of law or infringement of another person's rights.

22. Governing Law and Dispute Resolution

These Terms are governed by the laws of South Australia, Australia. Subject to the dispute resolution process below, the parties submit to the non-exclusive jurisdiction of the courts exercising jurisdiction in South Australia.

Before commencing court proceedings, a party must give the other party written notice of the dispute with enough detail for the dispute to be considered. The parties must then attempt in good faith to resolve the dispute.

If the dispute is not resolved within 30 days after notice is given, either party may commence proceedings in a court with jurisdiction, except where a party seeks urgent injunctive, equitable or similar relief.

23. Changes to these Terms

We may update these Terms from time to time. Unless we state otherwise, changes take effect when posted on this page.

If we make material changes, we will take reasonable steps to notify you before the changes take effect, such as by displaying a notice in the service or sending an email to the address associated with your account.

If you continue to use the service after the updated Terms take effect, you will be taken to have accepted the updated Terms. If you do not agree to the updated Terms, you must stop using the service and may cancel your account.

24. General

These Terms, together with any policies or terms incorporated by reference, form the entire agreement between you and us regarding the service.

You may not assign or transfer your rights or obligations under these Terms without our prior written consent. We may assign or transfer our rights and obligations as part of a merger, acquisition, restructure, sale of assets or similar transaction.

A failure or delay in enforcing a provision of these Terms does not waive our right to enforce that provision. If any provision of these Terms is found to be invalid, unlawful or unenforceable, that provision will be severed or read down to the minimum extent necessary, and the remaining provisions will continue in force.

Nothing in these Terms creates a partnership, joint venture, employment, agency or fiduciary relationship between you and us. Headings are for convenience and do not affect interpretation.
