Privacy Policy

Data we collect

How you sign in

You can create an account with Sign in with Apple, Sign in with Google, or email and password. We only receive the name and email your chosen provider shares with us (or that you enter directly) — we never see your Apple or Google password.

What we don't do

• We don't track you across other companies' apps or websites.
• We don't use your data for advertising, and we don't show ads.
• We don't sell or share your personal data with data brokers.
• We don't request an advertising identifier (IDFA), and there's no App Tracking Transparency prompt because we don't need one.

Where your data is stored

Your account and training data are stored using Google Firebase (Firebase Authentication and Cloud Firestore), Google's cloud backend platform. Access to your data is restricted to your own account — no other user of the app can read or write your records.

Analytics

We use Firebase Analytics to understand which screens and features are used, so we can improve the training plan. This is limited to a pseudonymous per-install identifier and in-app usage events (like screen views) — it isn't tied to your name or email, and isn't used for tracking or advertising.

Your choices

You can delete your account and all associated data at any time by contacting us at the email below. You can also sign out of the app at any time, which ends your session on that device.

Children's privacy

ShuttleSensei is not directed at children under 13, and we do not knowingly collect data from children under 13.

If this policy changes, we'll update the date at the top of this page.
