Parents can revoke app approval for supervised users on Android devices using the[Google Family Link](https://families.google/familylink/)app. If app approval is revoked for a supervised user, then that user will no longer be able to use your app. Google Play will notify you about the revocation.

## Before revocation

Google Play will include an`installID`in the Play Age Signals API (beta) response per user per device. You can store this`installID`on your app's backend server in anticipation of being notified about revoked app approvals.
| **Note:** The`installID`is generated per install and does not persist across re-installs or device resets to protect user privacy. The install ID allows Google to notify you that approval was revoked where providing this notice to you is required by law, and you are not permitted to use it for other purposes.

## After revocation

Google Play will notify you about revoked app approvals by listing the`installID`that was included in the Play Age Signals API response for that user on the**Revoked app approvals** tab on the[Age signals](https://play.google.com/console/developers/app/age-signals)page in your Google Play Console. You can also download a list of the revoked app approvals. Revoked install IDs are available for three months before being deleted.
