Delete your account
This page explains how to delete your Kotoba Dōjō account — the app published by Artsiom Chtrykov — and exactly what happens to your data when you do.
In the mobile app
- Open Kotoba Dōjō and sign in.
- Tap Self in the bottom navigation bar.
- Tap Account.
- Tap Delete account and confirm.
On the web
- Sign in at kotobadojo.com.
- Go to Self.
- Choose Delete account and confirm.
If you cannot sign in
Email privacy@kotobadojo.com from the address on the account and we will delete it for you. We aim to act within 30 days, as required under the GDPR.
What is deleted
Deletion is immediate and permanent. There is no grace period and no way for us to restore an account afterwards. The following are erased:
- Your account and sign-in details — email address, name and linked sign-in methods
- Your decks, cards, notes and any content you created
- Your study history, review schedule, streak, XP, level and achievements
- Your samurai, equipment and dojo arrangement
- Your friends, friend requests and invitations
- Any voice recordings you made, removed from storage before the account row itself
- Any decks you published to the community, along with their install and favourite counts
- Push notification tokens and any feedback you submitted
What is kept
Records we are legally required to retain: invoices and payment records associated with a paid subscription, kept for the period required by tax law (in Poland, five years from the end of the accounting year). These are held by our payment processors and contain billing details rather than study data. Deleting your account also stops any future billing, but does not itself cancel a subscription bought through Google Play or the App Store — cancel that in the store where you bought it.
Server logs may retain a technical record of requests for up to 30 days before rotating out. These are not linked to your study data.
If you simply stop using the app
You do not have to do anything for your data to stop identifying you. After 24 months with no training sessions we anonymize the account automatically: your email, name, avatar name and billing identifiers are permanently removed and your sign-in is severed, while anonymous study statistics and any decks you contributed are kept and can no longer be traced back to you. You never have to wait for this — deleting outright is available at any time.
