Step 1 — Generate and host the policy
Use this generator. You will get a public URL like your-app.freeprivacypolicy.app/privacy-policy that the stores will accept.
Step 2 — Paste the URL into App Store Connect
App Store Connect → My Apps → your app → App Information → Privacy Policy URL. Paste, save. The URL must be reachable when reviewers click; do not host it behind a login.
Step 3 — Paste the URL into Google Play Console
Play Console → your app → Policy → App content → Privacy policy. Paste the same URL. Then complete the Data Safety form so its declarations match the policy.
Step 4 — Link from inside the app
Place a "Privacy Policy" link in your Settings screen and in any signup flow. Both Apple and Google check that the link is reachable from inside the app, not just on the store listing.
