HitOne — Privacy Policy

Effective July 27, 2026

HitOne is a 3D tennis drill app. This policy explains what data the app handles, and it is intentionally short because we collect very little.

Using HitOne without an account

You can use HitOne fully without signing in. In that case your drills are stored only on your device and nothing personal is collected or transmitted to us.

If you create an account (optional)

Accounts exist so your drills can follow you across devices. If you sign in — with email and password, Sign in with Apple, or Google — we store:

• Your email address (or the private relay address Apple provides), used only to identify your account;
• An account identifier, used only to link your drills to your account;
• The drills you save, so they can sync to your other devices.

Authentication and storage are provided by Supabase, our backend service provider, which processes this data on our behalf. Apple or Google act as sign-in providers if you choose them; we receive only the email/identifier they share.

What we don't do

• No advertising and no ad networks.
• No analytics or behavioral profiling.
• No tracking across other companies' apps or websites.
• We never sell your data, and we never share it except with the service providers named above, as needed to run the app.

Deleting your data

You can delete your account at any time from inside the app: tap the person icon in the top-left corner, open your account, and choose Delete Account. This permanently removes your account and your synced drills from our servers. Drills stored locally on your device remain yours and can be removed by deleting them in the app or uninstalling it.

Children

HitOne is not directed at children under 13, and we do not knowingly collect personal information from them.

Changes

If this policy changes, the updated version will be posted at this address with a new effective date.
