Nucu Account Deletion

Last updated: 7/5/2026

App: Nucu Health (Android, Google Play — com.nucuhealth.app)
Developer: Nucu Oy

You can permanently delete your Nucu Health account and the personal data linked to it at any time. There are two ways to request deletion.

How to request deletion

Option 1 — From the Nucu Health mobile app (recommended, immediate)

  1. Open the Nucu Health app
  2. Go to Settings → General → Account Settings → Delete Account
  3. Confirm the action

The deletion takes effect immediately. You will be signed out and your account record on our backend is removed within minutes.

Option 2 — By email (for users who can no longer access the app)

Send a request from the email address registered on your Nucu Health account to info@nucubaby.com with:

  • Subject: Account deletion request
  • Body: your full name and the email address registered on the account

We verify your identity by replying to your registered email — you must confirm the request from that mailbox before we proceed. We complete the deletion within 30 days of receiving a verified request, in line with GDPR Art. 17.

What is deleted

When your account is deleted, we permanently remove from our systems:

  • Your user profile (name, email, account credentials in our identity provider, AWS Cognito)
  • All families you own, including the family record, baby records, sleep diary entries, and biometric history (heart rate, breathing rate, body movement, sleep stages)
  • All pad device pairings tied to your account
  • The X.509 client certificates issued to your paired pad(s) — these are revoked, so the pad cannot reach our cloud until it is re-paired by a new account
  • Cached data on your mobile device (local database, encrypted preferences, local files)
  • Caregiver invitations you sent or accepted

If you are the owner of a shared family, deleting your account also deletes the family and revokes access for any caregivers you invited. If you want to keep the family active, transfer ownership to another caregiver before deleting your account (Settings → Family → Manage members).

What is retained, and why

A small amount of data is retained after deletion, in line with our Privacy Policy:

  • Anonymised analytics (e.g. aggregated app usage) — these are not linked to your account and cannot identify you.
  • Crash reports (only if you opted in to crash reporting) — automatically deleted by Google Firebase Crashlytics within approximately 90 days.

None of this retained data is linked to your account or used to identify you.

Health Connect data

If you connected Nucu Health to Health Connect, the sleep and heart-rate records we wrote to Health Connect remain under your control inside Health Connect. Account deletion in Nucu Health does not remove them. To delete that data, open the Health Connect app on your phone and remove Nucu Health's data there.

Subscriptions

Account deletion does not cancel an active Google Play subscription. If you have an active Nucu Health subscription, cancel it in Google Play → Subscriptions before deleting your account, otherwise Google will keep billing you.

Export your data first (GDPR)

Under GDPR Art. 15 and 20, you have the right to a copy of your personal data before deletion. To request an export, email info@nucubaby.com with subject Data export request from your registered email, and we will send you a machine-readable copy within 30 days.

After deletion

  • Account deletion is irreversible. We cannot recover deleted data.
  • To use Nucu Health again, you must create a new account.
  • Previously paired pad devices can be re-paired with a new account.
