Privacy Policy

Effective August 9, 2026.

The short version

Your raw video never leaves your phone. All pose analysis runs on-device. Only derived movement measurements and a small set of still keyframes (with a skeleton drawn on them) are sent to our servers to generate coaching feedback.
You don't need to create an account to start — the app creates an anonymous account on your device.
We don't sell your data, and we don't show ads.
You can delete your account and every piece of associated data from inside the app at any time.

What we collect

Account: an anonymous account identifier created on first launch. If you later sign in (e.g. with Apple), the identifier from that sign-in.
Profile answers you optionally provide during onboarding: self-rating, goal, play frequency, most frustrating shot, paddle hand. All questions are skippable.
Analysis data: numeric movement measurements computed on your device (joint angles, timing, scores), the resulting coaching report, and up to ~10 still keyframe images per analysis showing your position with a skeleton overlay. The video itself is never uploaded.
Purchase state via RevenueCat and Apple: which subscription or credit pack you hold. We never see your payment details — Apple processes all payments.
Product analytics and crash reports (PostHog and Sentry): which screens are used and what crashed, without advertising identifiers and without tracking you across other apps.

How coaching is generated

Your measurements and keyframes are sent to an AI model (Google's Gemini API) to write the coaching text. Feedback is technique guidance only — not medical, health, or injury advice, and any skill-level range shown is an unofficial, form-based estimate, not an official DUPR rating.

Where data lives

Analysis results and account data are stored with Supabase. Keyframe images live in private storage only your account can access. Third-party processors: Supabase (hosting), Google (Gemini API — coaching text generation), Apple and RevenueCat (purchases), PostHog (analytics), Sentry (crash reporting). Each processes data only to provide its service to us.

Retention and deletion

Your data is kept while your account exists so your history and progress work. Deleting your account (in the app: Settings → Delete account & data) permanently removes your account, analyses, reports, keyframes, and purchase records from our systems. Apple retains its own purchase records per its policies.

Changes

If this policy changes materially we'll update the effective date here and note it in the app.
