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]
> **Note:** The `installID` does not persist across device resets to protect user privacy. The `installID` allows Google to notify you that approval was revoked where providing this notice to you is required by law, and you are not permitted to use it for other purposes.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 provides details about revoked app approvals by listing the
`installID` for that user on the **Revoked app approvals** tab on the
[Age signals](https://play.google.com/console/developers/app/age-signals) page in the Google Play Console. Here, you can download a
CSV file with a list of the revoked app approvals. Revoked `installID`
values are listed for 90 days before being deleted.

## Repeat approvals and revocations

If a parent re-approves the same app for a user and the device has not been
reset, the same `installID` is returned in the Play Age Signals API response
for the re-approved app.

If the app approval is revoked again, the same `installID` appears
as a new entry in the table on the **Revoked app approvals** tab
on the [Age signals](https://play.google.com/console/developers/app/age-signals) page. That means a single `installID` can appear
multiple times in the revoked app approvals table, once for each revocation.
