Privacy Policy

Last updated: February 28, 2026

Overview

Focus Bonsai ("the App") is developed by Stackforge GmbH. Your privacy matters to us. This policy explains what data the App collects, how it is used, and your choices.

Data Stored on Your Device

Focus Bonsai stores all user data locally on your device. This includes your focus sessions, garden collection, streaks, statistics, unlocked cosmetics, and preferences. No account or sign-up is required. This data is never transmitted to external servers unless you explicitly opt in to analytics.

Analytics (Optional)

If you have analytics enabled, the App may collect anonymous usage data through PostHog to help us improve the experience. This includes:

  • Product interaction data (e.g., which features are used)
  • Diagnostic data (e.g., crash reports)

This data is not linked to your identity. No personal identifiers are collected. You can opt out of analytics at any time in the App's settings.

Purchases & Subscriptions

If you purchase a subscription or the lifetime unlock, purchase receipts are processed by RevenueCat for subscription validation. RevenueCat stores only an anonymous app user ID — no personal data such as your name, email, or payment details is collected by us. Payment is handled entirely by Apple through your Apple ID account.

Data Sharing

We do not sell, rent, or share your data with third parties for advertising or marketing purposes. The only third-party services that may receive limited, anonymous data are:

  • PostHog — anonymous analytics (if opted in)
  • RevenueCat — subscription validation (if you make a purchase)

Children's Privacy

Focus Bonsai is rated 4+ and does not knowingly collect personal information from children. Since the App does not require an account and stores data only locally, no personal data from any user — including children — is collected by default.

Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated date. Continued use of the App after changes constitutes acceptance of the updated policy.
