How to request that your EEG Master account and the data associated with it be permanently deleted. This page applies to the EEG Master app for Android and iOS, published by Vector 265.
Email us from your account's email address and ask us to delete your account. We'll verify the request and permanently delete your profile, onboarding answers, and learning progress within 30 days. We don't currently offer in‑app self-service deletion, so every request is handled by a person, not a bot.
Send a message to the address below, from the same email you used to sign up for EEG Master. This is how we confirm the request is actually coming from the account owner.
In the body, confirm the account email address and state that you want your account and data deleted. This helps us find and action your request quickly.
We confirm the request matches an existing account, then permanently delete your account and the data listed below. This is done within 30 days of a verified request.
You'll receive a short confirmation once deletion is complete. If we can't verify the request (for example, it comes from a different address than the one on the account), we'll reply asking for confirmation instead of deleting anything.
A future in-app update will let you request deletion directly from the Profile screen. Until then, email is the only way to request it.
EEG Master stores your data in Google Firebase (Authentication for sign-in, Cloud Firestore for everything else). Here's exactly what happens to each category once your deletion request is processed:
| Data | What it is | Outcome |
|---|---|---|
| Account & sign-in | Email address, display name, authentication record | ● Deleted |
| Onboarding profile | Country, institution/workplace, professional role, learning goals, exam timeline | ● Deleted |
| Learning progress | Daily MCQ/flashcard/atlas activity logs, streaks, generated study plan, reminder time | ● Deleted |
| Locally scheduled reminders | Daily notification schedule on your own device | ● Deleted Never stored on our servers — removed automatically if you uninstall the app. |
| Deletion request record | The email address and date you contacted us for deletion | ● Kept 90 days Kept only for our own audit trail that the request was made and honored, then deleted. |
| Infrastructure backups | Google Cloud/Firebase's own short-lived operational backups | ● Up to 30 days Standard backup cycling on Google's infrastructure, outside our control; purged automatically. |
We never collect payment information, precise location, advertising identifiers, or patient health information in the first place, so there's nothing in those categories to delete.
