Delete my Kanzen account

Procedure for permanently deleting your account and associated data, in compliance with GDPR (article 17) and the Google Play and App Store policies.

Method 1 — From the app (recommended)

Deletion from the app is immediate and requires no waiting.

If you have uninstalled the app or lost access to your account, send an email to:

Subject: Kanzen account deletion

In the body of the message, please include:

We will process the deletion within 7 business days and send you a confirmation by email.

Email address, password, username, hanko, banner, friend code
SRS progress (kanji seen, levels, intervals)
Game statistics (Look-alikes, duels, seals)
Duel history and ranking
Friend relationships and invitations
Personal mnemonics (private)
Journey measurement events and screenshots attached to your feedback
Kanzen Plus subscription (the subscription itself must still be cancelled from your store account — Google Play, or the App Store where applicable)

Public mnemonics adopted or reacted to by other learners remain visible in the community library, but their link with your identity is irreversibly dissociated (author replaced by "Former user").
The feedback you sent us from the app (message, category, app version) is kept with no link whatsoever to your account, so it can keep guiding fixes. Any screenshot you attached is deleted.

This policy preserves the learning experience of other users without revealing your identity.

Production data: erased immediately on deletion from the app, or within 7 days for an email request.
Technical backups: automatically purged within 30 days as per the policy of our host Supabase (Ireland datacentre, EU).
Billing data retained by Apple or Google under their own terms (accounting obligations).
