Privacy Policy.

Who is responsible

The controller for this app is Alain Kessler, a sole proprietorship registered in Switzerland, operating under the brand Klar. For any privacy question or request, contact support@getklar.org.

What we collect

Account data (optional).You can play as a guest without an account. If you create an account or use Sign in with Apple, we store your email address to sign you in and to sync your premium status across your devices. With Sign in with Apple you may use Apple's private relay email; that works fine.

Purchase and subscription status. When you buy Promillo PRO, the purchase is processed by Apple. We receive only the resulting entitlement status (active or not) through our subscription provider RevenueCat. We never receive your card or payment details.

Anonymous install signal. On first launch the app sends a single anonymous event so we can count installs. It contains a random identifier generated on your device, the platform (iOS or Android), the app version and your app language. It contains no name, email, contacts, advertising identifier or location, and it is not linked to your account.

On your device only. Player names, chosen avatars and game settings stay on your device and are not sent to us.

What we do not do

No advertising and no ad networks. No cross-app or cross-site tracking, and no advertising identifier (IDFA). No location data, no access to your contacts, photos or microphone. We do not sell or rent personal data to anyone.

Why we process this data

To provide the app and your account, to unlock and restore Promillo PRO, and to understand how many people install the app. Legal bases under the GDPR are the performance of our contract with you (Art. 6 para. 1 lit. b) and our legitimate interest in basic, privacy friendly install statistics (Art. 6 para. 1 lit. f). The Swiss Data Protection Act (DSG) applies in parallel.

Service providers

We use a small set of processors, each only to run the service:

Apple for Sign in with Apple and for all payments and subscriptions. Supabase for account authentication and database hosting, located in the European Union. RevenueCat for managing subscription entitlements. These providers process data on our behalf under data processing agreements.

Where data is stored and how long

Account data is stored on Supabase servers in the European Union (Frankfurt region). We keep your account data for as long as your account exists. You can delete your account at any time in the app under Settings, which removes your account data from our systems. The anonymous install signal is aggregated and cannot be traced back to you.

Your rights

You have the right to access, correct, delete and export your personal data, and to object to or restrict its processing. The fastest way to delete everything is the in-app account deletion. For any other request, write to support@getklar.org. You also have the right to lodge a complaint with a data protection authority.

Children

Promillo is intended for a general audience and is not directed to children. We do not knowingly collect personal data from children under 13, or under 16 in the European Union. If you believe a child has provided us with personal data, contact us and we will delete it.
