Challenge Yourself — Manage & delete data

Account deletion

The current version does not create a YSFMARK account or a cloud profile. There is no account to close. You can still delete local data or ask us to delete support correspondence.

Delete information on your device

Use your operating system’s Clear storage/data or Delete App controls to remove locally stored quiz progress and preferences. Uninstalling or clearing data does not automatically delete Google service data, support emails, or operating-system backups.

Android: open Settings → Apps → the app → Storage → Clear storage/data. Menu names vary by device. Uninstalling also removes the active local installation; a later restore from a system backup may bring some data back.

iPhone/iPad: use Settings → General → iPhone/iPad Storage → the app → Delete App. Offload App keeps its documents and data. These instructions apply where an iOS version is installed.

Device backups

Your operating system may keep an app backup or transfer app data between devices, depending on its settings. Local deletion does not automatically remove an existing device backup. Manage those copies through your Android/Google or Apple/iCloud backup settings. We do not have access to your personal device backup.

Delete support correspondence

Email ysfmark@gmail.com with the subject “Data deletion — Challenge Yourself” from the address used to contact us. Tell us which correspondence you want removed. We aim to respond within 30 days and will explain any information we must retain for a legal obligation or an unresolved dispute. We request only what is necessary to identify your request; do not send identity documents unless a proportionate verification process is explained to you.

Third-party service data

Use the app’s advertising privacy options where available and your device’s advertising-ID controls. Clearing local app storage does not automatically delete Firebase or advertising service data. Because we do not have an account-to-device identity map, contact us to review whether a service record can reasonably be identified. See the app privacy policy and Google’s privacy information.
