This page explains how to request the deletion of your data for the Séréni app (published by the Séréni association). It supplements our privacy policy.
Séréni works without an account. Your data is stored first and foremost locally on your device: there is no online account to delete. There are two ways to erase your data.
Most Séréni data never leaves your phone or watch. You delete it yourself, immediately:
Both actions are permanent and require no request to the association.
For any data that may remain outside your device (for example an alert message passed on to a loved one through the notification service, or a contact request), write to:
contact@sereni-asso.fr — subject: “Data deletion request”.
Simply give the first name and, where applicable, the caregiver/senior link concerned. We handle the request within 30 days at most and confirm the deletion by e-mail. No proof of identity is required.
| Type of data | Where it is stored | How it is deleted |
|---|---|---|
| Profile (first name), caregiver/senior link, contact details of a loved one to alert | Locally on the device | Clear data / uninstall |
| Reminders and activities (appointments, medication, tasks) | Locally on the device | Clear data / uninstall |
| Wellbeing / health data (heart rate, sleep, steps…) | Locally, read-only; end-to-end encrypted sharing if enabled | Clear data / uninstall; sharing stops immediately |
| Technical notification identifier | Notification delivery service (provider) | Clear data / uninstall; request by e-mail |
| Alert messages passed on to a loved one (name, one-off location) | Passed on to the loved one through the notification service; not kept by the association | Automatic expiry on the service side; request by e-mail |
| Contact e-mail (if you write to us) | The association's mailbox | Request by e-mail |
Séréni does not sell, rent or transfer any data and shows no advertising. Local data exists as long as the app is installed and is deleted as soon as it is cleared or the app is uninstalled. Messages passed on through the notification service are short-lived and expire automatically on the provider's side. The association keeps no data beyond what the service needs, unless required by law; a contact e-mail is kept while your request is handled, then deleted.
In addition to erasure, you have the right of access, rectification, restriction, objection and portability (see the privacy policy). To exercise them: contact@sereni-asso.fr. You may also contact the CNIL (www.cnil.fr).
