Delete Your Account
Last updated: September 2026
You can delete your Hello Nabu account, and the personal data attached to it, at any time and without contacting us. This page explains how to do it on each platform and what happens to your data afterwards.
1. Delete from the mobile app
In the Hello Nabu app for Android or iOS:
Open the app and sign in
Open Settings from the menu
Scroll down to the Danger Zone section
Tap Delete Account, then confirm
Deletion runs immediately and signs you out. It cannot be undone.
2. Delete from the web app
At www.hellonabu.com:
Sign in to your account
Open Settings from your profile menu
Scroll down to the Danger Zone section
Select Delete Account, then confirm
3. Cancel your subscription first
Deleting your account does not cancel a paid subscription. If you subscribed through the App Store or Google Play, cancel it in your store account before deleting, otherwise the store keeps billing you. If you subscribed on the web, open the Subscription row in your settings to reach the billing portal and cancel there first.
4. What is deleted
Deleting your account permanently removes:
Your account and profile: name, username, email address, date of birth
Your sign-in credential, including the Firebase authentication record
Your learning data: progress, completed exercises, vocabulary, learning history
Content you created in the app, such as adventures, characters and personal notes
Your push notification tokens and notification preferences
Your consent records for marketing and analytics
Everything above is deleted from our database in a single operation as soon as you confirm. There is no recovery period and no way for us to restore it.
5. What we keep, and for how long
A small amount of data outlives the account, either because the law requires it or because it is no longer personal data:
Personal data is fully deleted within 30 days, except where retention is required by law
Transaction and billing records are kept for up to 10 years, as required by French tax law (Article L123-22 of the Code de commerce)
Crash reports and diagnostic data are kept for 90 days
AI-generated illustrations are kept as anonymous image files, with every link to your account removed
Section 10 of our Privacy Policy sets out our retention periods in full.
6. If you cannot delete the account yourself
Two kinds of account cannot be deleted from inside the app:
Accounts belonging to a company workspace, which your workspace administrator has to release first
Administrator accounts
If you have lost access to your account, or it falls into one of the cases above, write to contact@hellonabu.com or dpo@hellonabu.com from the email address you signed up with and ask for deletion. We handle these requests within 30 days.
