Privacy policy

Last updated: 12 September 2026

b-tracker is a personal budget and spending tracker. This policy explains what personal data the service processes and why. English governs if this policy and its Serbian translation differ. This policy is provided for transparency and is not legal advice.

What we collect

• Identity and profile data: your sign-in identifier, email address, and optional display name.
• Financial data you enter: Accounts, starting balances, currencies, Transactions, Transfers, Categories, descriptions, dates, recurring Series, and reminder choices.
• Preferences: your default currency, application time zone, week-start day, language, theme, and reminder settings.
• Correspondence: the email address, message contents, attachments, and other information you choose to send when you contact support or make a privacy request.
• Technical and operational data: information needed to authenticate requests, operate the apps, diagnose failures, protect the service, and understand service health. Operational logs may include timestamps, request paths, status codes, device or app information, and network identifiers such as an IP address.

The public pages at b-tracker.com are static, require no sign-in, and run no client-side JavaScript. The b-tracker apps use the local storage or secure credential storage provided by your browser or device to keep session and preference information.

How we use your data

We process this data to provide the features you request, calculate balances and reports, synchronise your data across signed-in devices, deliver reminders, secure and troubleshoot the service, respond to support and privacy requests, and meet legal obligations. We do not sell personal data or use it for targeted advertising.

Service providers

We use service providers only where they help operate b-tracker:

• Auth0 provides authentication, account identity, and sign-in connections.
• Microsoft Azure hosts the applications, databases, backups, and operational monitoring.
• Google processes information when you choose Google sign-in. Google’s own privacy terms also apply to that sign-in interaction.
• Expo and EAS provide mobile build and distribution services. They may process build, device, and delivery information needed to distribute the mobile app.
• Email delivery and mailbox providers deliver service emails and operate the support@b-tracker.com mailbox. The production vendors are being selected as part of launch readiness; this policy will name them before those services process user data.

Providers process data under their own service terms and only for the functions described above. A provider may use infrastructure in more than one country, subject to its safeguards and applicable law.

Retention and deletion

We keep active account data while you use b-tracker. When you complete User Deletion, removal of your b-tracker data and sign-in identity is immediate and irreversible. There is no grace period and signing up again creates a new, empty user.

Deleted data may remain in disaster-recovery backups for up to 7 days. Backups are not used to restore an individual account. Operational logs are retained for up to 30 days. If a disaster requires restoring an older backup, data deleted after that backup was created could temporarily reappear and would need to be deleted again.

Your choices and rights

You can view and correct much of your information in the apps and can delete your b-tracker account from the Profile area. Depending on where you live, you may also have rights to access, correct, delete, restrict, object to processing, or receive a copy of your personal data.

There is no self-service export. Ask support@b-tracker.com for a copy of your data or to exercise another privacy right. We may need to verify your identity before acting on a request.

Contact

Questions, requests, or complaints about this policy can be sent to support@b-tracker.com. You may also contact the data-protection authority that applies where you live.
