Our principle

Each Sparlen app works first with no account. Your data stays on the iPhone until you turn on Sparlen Plus. We do not sell your data, show ads, or run cross-app tracking.

Website: app ideas

On sparlen-app.com, “Participate” lets you suggest an app idea for the Sparlen ecosystem. If you submit the form, we collect your idea and your email address.

Purpose: review your suggestion and reply if needed. Legal basis: your consent when you send the form. Hosting: Supabase, Europe (Paris). No ads, no resale, no ad tracking.

To access, correct, or delete a suggestion tied to your email, write to hello.ngdeau@gmail.com.

Sparlen account

Sign in with Apple creates one Sparlen account, reused by Sparlen apps. No email, Google or other login. The Apple user identifier (possibly hidden) is the only account id.

Sparlen Plus

Sparlen Plus is optional and billed by Apple as a Sparlen global subscription. It lets you back up and restore your Sparlen apps’ data on another iPhone. Hosting: Supabase, Europe (Paris). This website: Ovh, France.

Reminders and notifications stay on-device. Sparlen does not send server notifications.

Two separate deletions

Local delete in the app you choose does not erase Sparlen Plus.

Your rights

You can access, correct or delete your data in the relevant app, or email hello.ngdeau@gmail.com. You may also contact the Cnil in France.

Sparlen apps are not directed at children under 16.
