Delete your Fusen account

This page explains how to delete your Fusen account and what happens to your information. Fusen is made by lapis, an individual developer.

Before you delete it

Unused paid credits and plan credits are lost, and a monthly plan ends at once, without a refund. If a recent purchase can still be refunded under our refund policy, ask for the refund first.
Your notebook is not affected (see below). Export a backup if you also plan to uninstall the app.

The account is deleted at once. This also signs the device out of sync.

If you no longer have the app, email support@fusen.ink with the subject "Delete my account":

send it from the address of the account: the Gmail or Google address you signed in with, or the address you signed in with by email;
if you cannot send from that address, tell us which address it is. We will email it to confirm before deleting anything.

We delete the account within 30 days and reply when it is done.

Your account: email address, Google account ID and sign-in sessions on every device.
Your free, plan and paid credits, and your monthly plan. Your customer record at Stripe, if you had a plan, is deleted too.
Your usage records, and the answers you rated and problems you reported.

A small record for 35 days (a year if the account was blocked for abuse), so that deleting and recreating an account can't be used to get extra free credits. It holds your Google account ID or a hash of your email address, the free credits left that month, the number of requests the AI declined, and whether the account was blocked. If you sign in again during that time, the new account starts with those values.
Purchase records, as tax law requires: at least 7 years after the year of the purchase. They are no longer linked to an account you can sign in to. Stripe keeps its own records of your payments.
Server logs for up to 30 days. They hold request times and results, never the text you translated.
Backups of our database for up to 35 days, used only to recover from a failure.
Anonymous usage statistics already added to totals. They were never linked to your account.

Deleting the account does not touch your notebook, which is on your device and, if you used sync, in your own Google Drive. To delete those too:

On the device: uninstall the app, or clear its storage in Android's settings. Export a backup first if you want to keep your words.
In Google Drive: in the app, Settings → Account and sync → Delete synced data. Without the app, open Google Drive on the web, go to Settings → Manage apps, find Fusen, and choose Delete hidden app data.
Google access: remove Fusen in your Google account under Security → Third-party apps & services.
