Delete your Cornerstone account

App: Cornerstone: Exam Study · Developer: GroundLearn

An account in Cornerstone is optional. It exists only to back your study progress up so that a reinstall or a new phone does not start you over. If you have never created one, there is nothing to delete — nothing about your studying has ever left your device.

How to delete it, in the app

Open Cornerstone and go to Profile → Account → Delete account, then confirm. The account and everything backed up under it are removed immediately, and the app returns to its signed-out state with your progress still on the device.

This is the whole process and it needs no email.

Or by email

If you no longer have the app installed, email contactgroundlearn@gmail.com from the address your account uses, with the subject Delete my account. You will get a reply confirming the deletion. If you email from a different address, you will be asked to confirm ownership of the account address first — otherwise anyone could delete anyone’s data by knowing their email address.

Signing out is not deleting. The app offers both, and signing out leaves the data on your device exactly as it is and leaves the backup in place.

Delete your progress without deleting your account

If you only want a clean run at the syllabus, you do not have to delete anything permanent.

In the app, go to Profile → Account → Reset progress, then confirm. That erases, from this device:

• topic mastery and card progress
• bookmarked cards and questions
• your review queue
• your study day history and streak
• your question and accuracy counts
• your mock exam scores

Your account is not touched, and neither is your subscription. If you are signed in, the backup is overwritten the next time this device syncs, so the reset reaches the copy held on our side as well. There is no confirmation email and nothing to wait for.

It cannot be undone, which is why it asks twice.

What is deleted

Everything held on our side, which is the account and the study data backed up under it:

The account and its data are removed within 30 days of the request. Copies inside routine encrypted database backups are overwritten as those backups age out, within a further 90 days, after which nothing remains.

What is not deleted, and why

Anything stored on your phone. The app keeps your progress locally whether or not you have an account, and deleting your account does not remove that copy. You can clear it yourself with Profile → Account → Reset progress (above), or by deleting the app’s storage from Android’s system settings, or by uninstalling the app.

Your subscription. Cornerstone Plus is billed by Google Play, not by us, and deleting your account does not cancel it. Cancel it in the Play Store app under Payments and subscriptions, or at https://play.google.com/store/account/subscriptions. An account and a subscription are separate things — a subscription follows your Google Play account, not a Cornerstone account, and works with no Cornerstone account at all.

Your purchase history at Google. Records of a purchase are held by Google Play under Google’s own policies, and are not ours to delete. RevenueCat, which checks whether a subscription is active, holds the purchase receipt Google issued together with an anonymous identifier it generates for the installation. Neither is linked to a Cornerstone account, so deleting the account does not affect them; to have those removed as well, say so in the same email and they will be deleted too.
