The quick way is in the app: tap ONLINE, scroll to the bottom, and choose delete account. It takes effect immediately — no waiting period, no email required.
Finished games keep an anonymized “Deleted player” entry so your former opponents' results stay intact — nothing in it can be traced back to you. Solo scores and settings stored on your own device are yours; uninstalling the app removes them.
Lost the device or uninstalled already? Email erik@ducktype.tech from any address and tell us the display name and friend code (if you remember them) — we'll delete the account for you.
Everything we store and why is described in the privacy policy.
