Account Deletion

You can delete your SUFX account at any time. This page explains the steps and what happens to your data afterwards.

Operator

SUFX is operated by Ilia Gavrichenko, a private individual based in Hungary.

• Postal address: 1027 Budapest, Kapas utca 21, Hungary
• Contact: [email protected]

How to delete your account

From the app (recommended)

1. Open SUFX on your phone.
2. On the Home screen, tap the person icon at the top (Profile), then Account and security → Delete account.
3. Confirm the deletion. The app signs you out as soon as the request is accepted.

By email

If you cannot access the in-app flow, send an account-deletion request to [email protected] from the email address registered on your account. We will action the request within five business days, and in any event no later than one month, as required by GDPR Article 12(3).

Delete some data without deleting your account

You can delete individual items in the app at any time: saved words, notes, essays, collections, and search history. To ask us to delete other data without deleting your account, email [email protected] from your registered email.

Export your data before deletion

If you want a copy of your data before deletion, request an export by emailing [email protected] from your registered email. Once the deletion is processed, the data cannot be recovered.

What gets deleted

The following data is permanently removed:

• Your email address, name, profile picture, and OAuth links.
• Your vocabulary, review history, essay drafts, notes, and other learning content.
• Your push-notification tokens and notification preferences.
• Your subscription record in our database (the underlying purchase remains with the App Store or Google Play; see “What does not get deleted” below).

What does not get deleted

• Your Apple ID or Google account itself — SUFX only removes the link between your SUFX account and the third-party account. You may separately revoke “Sign in with Apple” at Settings → Apple ID → Sign in with Apple on your iPhone, and “Sign in with Google” at myaccount.google.com → Security → Third-party apps.
• Active store subscriptions — deleting your SUFX account does not cancel an active subscription with Apple or Google. You must cancel the subscription separately, before account deletion, or you will continue to be billed.
• Encrypted backups — database backups taken before deletion are kept for up to 8 days. They are not used to restore your account and are deleted automatically when they expire.
• Subscription event records — the purchase events we receive from the App Store or Google Play via RevenueCat (for example product, price, dates, store transaction identifiers, country, how you found the app, and the internal account ID they belonged to). They do not contain your email address or name. We keep them as records of past purchases.
• Copies held by our service providers — linked to your internal account ID, not deleted together with your account: error reports (Sentry) are deleted after up to 90 days and server logs (Grafana Labs) after up to 30 days; product analytics (PostHog) and your subscription record at RevenueCat are kept until we delete them. To ask us to delete them, email [email protected].
• Email logs — which emails we sent you and whether they arrived (no address and no message text), kept for up to 12 months to handle bounces and spam reports.
• Anonymised aggregate metrics — counts that contain no personal identifiers may be retained indefinitely for service-quality analysis.

How to cancel a subscription

• iOS: Settings → [your name] → Subscriptions → SUFX → Cancel Subscription.
• Android: Google Play → Profile → Payments & subscriptions → Subscriptions → SUFX → Cancel.

Retention timeline

• Immediately (when you delete in the app): account access is revoked, authentication tokens are invalidated, and your account and learning data are removed from our database. Requests by email are handled within five business days.
• Up to 8 days: encrypted backups may still contain your data; they are then deleted.
• The records listed under “What does not get deleted” are kept as described there.

Re-registration after deletion

You may register a new SUFX account at any time after deleting your previous one. There is no cooldown period. The new account is independent of the deleted account:

• it has a new internal identifier;
• previous learning content (vocabulary, review history, essay drafts) cannot be restored, even if you register with the same email address or OAuth provider;
• previous subscription history is not transferred. If the original store subscription is still active (because you did not cancel before deletion), the new account will recognise it once you sign in with the same Apple ID or Google account.
