Review linked apps and account connection privacy

Review each Google connection by type

Google's linked-app guide provides filters for Sign in with Google, Linked account, and Access to your Google Account. Select the app and See details. If there is more than one link, review each relevant entry rather than assuming one removal covers every permission. Google: distinct linked-app types and removal effects

1. For Google sign-in, the guide documents Stop using Sign in with Google. For an app's access to Google data, it documents Remove access. For Google's access to a linked app, it documents Delete link. Read the stated effects and lost features before confirming the relevant choice. Google: distinct linked-app types and removal effects

Handle information already copied through the app's own route

Google says revoking data access prevents further access, but an app may retain copies it already received. Contact the app developer for any request about that data. Review the developer's privacy and security information, and keep account passwords out of a third-party app's own forms. Google: authorized data access and earlier copies

Review Google sign-in prompts separately

Google's sign-in help documents a Sign-in prompts toggle in its sign-in settings. Disabling it affects prompts across signed-in Android devices, Chrome and some other browsers, with an explicit exception for browsers it does not cover. A prompt preference is a different task from reviewing granted data access. Google: sign-in profile sharing and prompts

Review the Apple app or developer before stopping sign-in

Apple's current route on iPhone or iPad is Settings > your name > Sign in with Apple. Select the app to review originally shared information. The documented Delete control stops that sign-in relationship and signs the app out on the device. Apple says signing in with Apple again returns to the same app account. Check how access will work before changing it. Apple: app review, developer scope and forwarding

Review the forwarding choice without confusing it with account deletion

Apple describes Hide My Email as a random relay address forwarding to a personal address. Review whether the app needs to reach that inbox before changing the relay. Hiding the address from the app does not describe deletion of its account information. Apple: first sign-in and private email relay

The management guide places the forwarding control under Settings > your name > iCloud > Hide My Email. Select the app or developer and review Forward To. A forwarding change can affect all apps associated with the same developer. Apple: app review, developer scope and forwarding

Use the separate Automatic Sign-in list where applicable

For supported apps on iOS 26 or iPadOS 26 and later, Apple documents Settings > your name > Media & Purchases > View Account > Connected Accounts. Select the account to review the last device used. Its Disconnect control does not automatically end the app's existing sessions. Review the app's own account and session controls if that is the concern.
