This privacy policy describes how Ketelaar Techniek B.V. processes personal data for KT-Control. Contact: info@ketelaartechniek.nl.
Data and purposes
For your account, we process your name, email address, optional phone number, password hash and, when using Google sign-in, your Google ID. We use this data for sign-in, account management and communications about your account.
For operation and security, we process app permissions, unit links, switching commands, log entries and IP addresses in security logs. Push tokens and notification preferences are needed to deliver the notifications you choose. We use language and favourites to personalise the app.
The installer manages installation and unit data, including the unit’s user list. This data is separate from your app account.
Retention periods
We keep account data while your account exists. When you delete your account, we erase the account data and app links described above. Audit and switching logs are retained without your account identity for up to 12 months after the event.
Notifications in your personal inbox are cleaned up after 30 days. Sessions expire after inactivity; remember-me tokens are valid for up to 180 days. Verification and reset links are temporary and are erased when you delete your account.
Unit data is managed by the installer and is not automatically deleted when you delete your app account. Ask the installer for access to, correction or deletion of that data.
Sharing and external services
If you sign in with Google, we use Google for that sign-in. For push notifications, we use your browser or device’s push service: Google, Apple, Mozilla or Microsoft. Account emails use the configured email service. We do not sell personal data or use advertising or advertising tracking.
Security
The production app uses HTTPS. The server checks access permissions and protects forms with CSRF checks. Passwords are stored as hashes; the app does not store readable account passwords.
Your rights
You can request access to, correction or deletion of your personal data via info@ketelaartechniek.nl. You can change your name, phone number and language under Account. To delete your account, use the app or submit an email request; we process it within 30 days.
Policy date: 5 November 2026.
