Delete Your Account and Data
Applies to: ProtoQuiz (EMS ProtoQuiz) for iOS and Android, published by ProtoQuiz LLC · Last updated: October 19, 2026
ProtoQuiz has no sign-up. The app creates an anonymous account for you automatically on first launch — you never provide a name, email address, or password. Deleting that anonymous account removes the data tied to it.
How to delete your account
You can delete your account and its data from inside the app, on either platform:
- Open ProtoQuiz on your device.
- Go to the Profile tab.
- Scroll to Delete Account & Data.
- Confirm when prompted.
The app signs you out, removes your anonymous sign-in, clears its data on your device and sends us a deletion request. We then delete the server data listed below. The app returns to its first-launch state.
If you can no longer open the app
Deleting the app from your device does not delete your data from our servers. If you have already uninstalled ProtoQuiz, the simplest route is to reinstall it and use the Profile screen — your anonymous account is restored on the same device, so the delete option will remove the right record.
If that is not possible, email [email protected] and we will help. Please note that because accounts are anonymous and hold no name or email address, we may need additional details from you — such as your approximate first-use date and the protocol document you uploaded — to identify your record with confidence.
What is deleted
| Data | What happens |
|---|---|
| Anonymous account identifier | Deleted |
| Your link to protocol documents you uploaded | Deleted |
| A de-identified copy of the protocol document (no link to you) | Kept, so we don't have to re-process the same agency protocol for the next person who uploads it. See the Privacy Policy. |
| Quiz progress, scores, and history | Deleted |
| Display name and leaderboard entry (from the retired Compete mode) | Deleted |
| Support messages you sent us | Deleted on request |
What is kept, and for how long
| Data | Retention |
|---|---|
| Crash reports and server logs (not linked to your identity) | Up to 90 days, then deleted automatically |
| Database backups | Up to 30 days, then overwritten |
| Census facts drawn from a protocol you uploaded (never linked to you) | Kept as part of the EMS Protocol Census; see the Privacy Policy |
| Aggregate, anonymised usage counts that cannot identify you or your device | Retained indefinitely |
| Purchase and transaction records | Retained as required by tax and accounting law |
Subscriptions must be cancelled separately
Deleting your account does not cancel a paid subscription. Subscriptions are managed by Apple or Google, not by us, so we cannot cancel one on your behalf.
Cancel before deleting your account:
- Android: Play Store › profile icon › Payments & subscriptions › Subscriptions › ProtoQuiz › Cancel.
- iOS: Settings › your name › Subscriptions › ProtoQuiz › Cancel Subscription.
