Terms of Service
Last updated: 4 August 2026
Welcome to Best Tracker. Please read these terms carefully before using our products and services. By using Best Tracker, you confirm that you understand and agree to all of the terms set out here.
1. What the service covers
Best Tracker provides personal bookkeeping, bill splitting, shared ledgers, statement import, AI bookkeeping, AI auto-logging (bulk recognition from screenshots and shortcut-based logging), the AI ledger connector and reporting. The exact scope may change with the product version, device operating system or operational arrangements.
2. AI auto-logging
AI auto-logging relies on screenshots you provide yourself, or screen captures produced through a system shortcut. Those images are used solely to recognise the entries they contain and create bookkeeping records; the results are stored as text in your ledger. Recognition may be imperfect — you can review and edit entries both before and after they are filed, and you are responsible for confirming that your final records are accurate.
3. The AI ledger connector
The AI ledger connector is built on the MCP protocol and lets you authorise a third-party AI agent to access and act on your ledger data. Authorisation is initiated entirely by you, its scope is yours to choose, and it can be revoked at any time inside the app. You are responsible for assessing the reliability of any agent you connect. We do not accept liability for losses arising directly from data processing, mistaken actions or data leakage caused by a third-party agent you have authorised, but we will provide the assistance you need to revoke access and inspect activity records.
4. Your account and its security
You should keep your account, verification codes and the devices you sign in on secure. Losses caused by disclosing or lending your account, or by failing to keep your device secure, are your own responsibility. If you notice anything unusual about your account, please contact us promptly.
5. Acceptable use
You may not use this service for anything unlawful, to infringe the rights of others, to interfere with the normal operation of the product or to circumvent its security measures. You may not upload malicious code, unlawful content or material that infringes third-party rights.
6. Your data and content
The ledgers, entries, notes and images you enter or upload belong to you or to the relevant rights holder. We process that data only to the extent necessary to provide services such as syncing, recognition, reporting and backup.
7. Membership and paid services
Some advanced features may require a membership or a separate payment. Pricing, service periods, auto-renewal and refund conditions are governed by what is shown on the purchase page and by the rules of the relevant platform.
8. Changes to and suspension of the service
We may update, suspend or adjust the service in order to improve it, fix problems or comply with legal requirements. Where a change materially affects your rights, we will notify you by reasonable means.
9. Disclaimer
Best Tracker is a bookkeeping and data-organisation tool. Reports and AI recognition results are for reference only. You should verify your records against your actual receipts and your own judgement.
10. Contacting us
If you have questions about these terms or about using the service, you can reach us through the feedback option in the app or via the contact details we publish officially.
