Deleting your account and data

YOSOMICHI · Last updated 2 September 2026

We won't try to talk you out of it. The way out sits on one screen. This page is the steps, plus an honest account of what actually goes and what stays.

Deletion can't be undone. Your map and everything you've walked are gone for good. If you want to keep any of it, use Export before you delete.

1. From the app

  1. Open YOSOMICHI
  2. Go to Settings
  3. Choose Delete account and data
  4. Read what will go, and answer two confirmations

The moment we accept it, writing stops. If an old session is still signed in on another phone, it can no longer read or write either.

We then show you a receipt code, once. Keep it if you'd like to check on progress later — deletion goes ahead whether you keep it or not.

2. If you've already removed the app

If you never signed in (the default)

YOSOMICHI needs no account, and we hold no email address or phone number. Which means we have no way of telling which data is yours. That's deliberate: we don't keep anything that could match you to your rows.

So: deleting the app clears what's on the phone (your notes live only there, so they go with it). For the server side, reinstall and use the steps above, or write to us if you kept a receipt code.

If you signed in with Apple or Google

Write to [email protected] from the address you signed in with, with “Delete my account” as the subject. We'll verify and run the same process.

3. What goes

If you ever carried an account over to a new device, the earlier one goes too. We follow the chain back, so nothing is left stranded under an old name.

4. What stays

Only the fact that a deletion was accepted. It holds nothing that points to you — a string no one can trace back, and a date.

WhatFor how longWhy
Processing detail 30 days So a failure part-way through can be traced
The receipt (non-identifying) 180 days So “yes, this was accepted” can still be confirmed

When those dates arrive, the rows are actually removed. Not just promised.

5. About your notes

Anything you wrote has been on your device only, from the start. It never reached our servers. Deleting your account erases it along with the key that opens it.
