Delete CHAC data

Signing in to CHAC is optional. If you never signed in, CHAC holds no account and no server copy of your progress, and only the local steps below apply.

Delete your account and its synced data

If you signed in with Google or Apple, delete the account from inside the app:

Open CHAC and go to Profile.
Under Account, choose Delete account.
Choose Confirm delete.

This immediately deletes your CHAC account and the synced copy of your learning progress. Nothing is retained after deletion. The progress saved on your device is left in place so you can keep learning offline; remove it with the local steps below.

If you can no longer sign in and need the account removed, email pim@vogtov.com from the address you signed in with, and VOGTOV will delete it for you.

What account deletion removes

Deleting your account removes the email address, name, and account identifier held by CHAC's authentication provider, the synced copy of your learning progress, your email-updates choice and its internal audience record. The progress copy includes streak, per-character mastery and review counts, review scheduling, recent review history, and chamber completions.

Delete your local CHAC data

On iPhone or iPad, press and hold the CHAC app icon.
Choose Remove App, then Delete App.
Do not choose Offload App if your goal is to remove local progress, because offloading can preserve app data.

On another platform, use that platform's app settings to clear CHAC storage or uninstall the app.

What removing the app removes

Deleting CHAC removes the local learning progress held by the app on that device, including lesson progress, review history, streak information, and locally saved learning preferences. It does not delete an account, so delete the account first if you have one.

Backups

Your device or cloud-backup provider may keep an encrypted backup until it is replaced or removed under that provider's own retention schedule. VOGTOV cannot access or delete a personal device backup.
