Delete my data

Last updated 2026-09-18

Everything the game knows about you on this phone is listed below, and this button removes all of it. If you also saved an account, that is deleted separately.

What this deletes

Your pearls, depth record, upgrades and Knowledge
Your Bestiary and every sighting
Your streak and today’s Daily catch
The tutorial tips you have seen (they will show again)

This cannot be undone. Unless you made a cloud copy, there is nothing anywhere else to restore it from.

Uninstalling the app does the same thing. To stop the ads collecting anything, reset or delete your advertising identifier in your phone’s settings.

If you saved an account

Open the app and go to Settings > Delete my account, type the word it asks for and confirm. The account is deleted straight away; you do not have to write to anyone.

What this deletes

Your email address, and the account itself
The cloud copy of your save, if you ever pressed “Back up now”

Deleting the account removes the copy we hold, not the progress on this phone. Use the button above for that.

Nothing is kept afterwards — the rows are deleted, not flagged, and there is no retention period. If you no longer have the app installed, write to myt.developers@gmail.com from the address you saved and we will delete the account for you.
