Privacy Policy

1 Information We Collect

Groov collects only what it needs to keep your habits in sync across your devices and to coach you. We do not sell your data, we show no advertising, and we use no advertising identifiers. The only usage analytics are a few anonymous, aggregated event counts (for example “a habit was created”) with no account id, habit names or free text, so they cannot be tied to you.

We do not collect your location, contacts, payment details, advertising identifiers or any government-issued identifiers. Apple lets you hide your real email address when you sign in with Apple; we only receive what you approve.

2 How We Use Your Information

Your information is used only to:

• Create and sign you in to your account
• Sync your habits, completions, challenges and settings across your devices and restore them after a reinstall
• Generate your daily nudge and weekly or monthly reflection (see section 3)
• Find and fix crashes

We do not use your data to build advertising profiles or to infer sensitive characteristics about you.

3 AI Coaching

Groov's AI coach writes a short daily nudge and, on request, a weekly or monthly reflection. To do that, our server sends the following to Anthropic's Claude API: your habit names and icons, your completion statistics for the recent period (counts, streaks and completion rates), how long you have been using Groov, and your display name.

Anthropic processes this under its commercial API terms, which do not permit using the data to train its models. The generated message is cached on our server so it is not regenerated every time you open the app, and it is deleted with your account.

4 Data Storage & Security

Your account and habit data are stored with Supabase. Every database table enforces row-level security, so an account can only read and write its own records.

• Data travels over HTTPS and is encrypted at rest by Supabase.
• Passwords are hashed by Supabase's authentication service; we never see them.
• Sign-in tokens are stored on your device so you stay signed in; the app keeps a local copy of your habit data so it works offline.
• The key used to call the AI service lives only on our server and is never shipped inside the app.

5 Who Processes Your Data

We do not sell, rent or share your personal information with anyone for their own purposes. These providers process data on our instructions:

We may also disclose data if required by law or to protect the rights and safety of users, and if Groov is ever transferred to a new owner your data would move with it under protections equivalent to this policy.

6 Notifications

All Groov reminders are scheduled locally on your device. We do not run a push notification service and do not hold push tokens. You can change or disable every reminder in the app's Settings, or turn off notifications for Groov in your device settings.

7 Children's Privacy

Groov is intended for users aged 13 and older (or the minimum age for online services in your country). We do not knowingly collect personal information from children under that age. If you believe a child has created an account, contact us (section 12) and we will delete it.

8 Your Rights & Choices

• Access and correct: everything we hold about you is visible and editable in the app (habits, completions, challenges, settings, display name).
• Delete: clear your habit data or delete your whole account from Settings at any time, without contacting us (section 9).
• Notifications, sounds and haptics: switch each off in Settings.
• Photos: revoke photo access in your device settings; habits keep working with an emoji icon.
• Password: reset it from Settings or from the "Forgot password?" link on the sign-in screen.
• If you are in the EU, UK, California or another region with privacy rights, you can also ask us to access, correct, port or delete your data, or object to processing, by contacting us.

9 Deleting Your Data or Account

If you can no longer sign in, contact us (section 12) with the email address on the account and we will delete it for you within 30 days.

Guest accounts. You can use Groov without creating an account. A guest account is a random identifier with no email, name or other personal data attached; your habits sync to it so they are not lost if the app is reinstalled on the same device. Adding an email, Apple or Google sign-in later keeps the same account. Signing out of a guest account without adding a sign-in orphans it, and orphaned guest accounts are deleted after 90 days.

Deletion is irreversible. Crash reports are retained by Sentry for 90 days and contain no habit data. Aptabase usage counts are anonymous and cannot be linked to an account, so there is nothing to delete.

10 California & Other Regional Rights

If you are a California resident you have the right to know what personal information we collect, to request its deletion, and not to be discriminated against for exercising those rights. We do not sell or share personal information for cross-context advertising, so there is nothing to opt out of. Residents of the EU, UK and other regions with similar laws have equivalent rights. To exercise any of them, use the in-app controls above or contact us.

11 Changes to This Policy

If this policy changes in a way that matters, we will update the date at the top of this page and mention it in the app's release notes. The current version always lives at this address.
