You can delete your CertStack account yourself from inside the app, or ask us to do it by email. You can also ask us to delete some of your data while keeping your account. This page covers all three.

Delete your whole account from the app

1. Open CertStack and sign in.
2. Go to Settings, then Account.
3. Tap Delete Account and confirm.

Deletion starts immediately. Your sign-in is removed right away and your study data is removed within 30 days. This cannot be undone.

Delete your whole account by email

If you cannot open the app, or you no longer have the device, email us from the address on the account. We will confirm it is you, delete the account, and reply when it is done.

Email us to delete my account

Or write to info@certstack.app with the subject "Delete my CertStack account".

Delete some of your data and keep your account

You can ask us to delete part of your data, for example your AI tutor conversations, your practice exam history, or your flashcard progress, while keeping the account itself. Tell us which data you mean and we will remove it within 30 days and reply when it is done.

Email us to delete some of my data

Or write to info@certstack.app with the subject "Delete some of my CertStack data".

What is deleted

• Your sign-in credentials and profile: name, email address, and photo.
• Your study data: quiz and practice exam attempts, study sessions, flashcard progress, bookmarks, and flashcards or collections you created.
• Your AI tutor conversations.

What is kept

• Anonymized, aggregated usage statistics that cannot be linked back to you.
• Purchase records that Google Play or the law require us to keep, for the period required.

Your subscription

Deleting your account does not cancel a paid subscription. Subscriptions are billed by Google Play, so cancel there first: open the Play Store, tap your profile picture, then Payments and subscriptions, then Subscriptions, and cancel CertStack. Otherwise Google Play may keep billing you for an account that no longer exists.

Timing

Account access ends immediately. Personal data is deleted within 30 days.
