Delete your Fletch! account
This is the “Deleting your data” section of the privacy policy, on a page of its own.
You can delete your account yourself, at once, from inside the game, on iPhone and on Android from version 1.0.216 (update the game from Google Play if you do not see it): Settings → Cloud Save → Delete cloud account (in earlier versions: Settings → Account & Premium → Cloud save → Delete account, and for a backup made without signing in the confirmation reads Delete cloud backup). You confirm who you are first (with Google if you signed in more than a few minutes ago, your password for an email account, or on iPhone Sign in with Apple), and the game then removes your cloud save, any public profile and your sign-in account, and backs nothing up again unless you sign in again. It works for every way of signing in, including Sign in with Apple with a hidden email address, where an email from you could not be matched to the account. If you used Sign in with Apple, the game also asks Apple to revoke its access. The progress on your phone stays; uninstalling the app removes that local copy immediately.
Deleting the account does not cancel a subscription, which is billed by the store: on Android manage it in the Google Play Store → Payments & subscriptions → Subscriptions; on iPhone in Settings → your name → Subscriptions. The one record we keep is the pseudonymous invite record described above, if a friend code was ever redeemed between two accounts: it holds only anonymous account identifiers and the code, and it is kept so that no account can be referred twice.
If your version of the game has no Delete account, or you cannot open the game, or it is no longer installed, email support@jogiba.com from the address you signed in with (on an earlier Android version you can instead include your in-game friend code) and we will delete your cloud save and account within 30 days. To limit ad personalisation, reset or delete your advertising ID in Android Settings → Google → Ads.
To limit ad personalisation on iPhone, turn off tracking for Fletch! in Settings → Privacy & Security → Tracking.
For everything the game stores and why, read the privacy policy.
