NO customer database
I do not maintain a customer database. Websites and apps published by me do not have access to or use your personal information.
NO personal information
I do not collect or store personal data. If you use the contact form, your e-mail address will only be used to send a reply, after which it will be deleted.
NO analytics
Websites and apps published by me do not use analytics or other systems to record your behaviour or the way you use them. Clicks, taps, keystrokes or other activities are not logged. You can disable Apple’s own analytics systems; here you find instructions for iOS and macOS.
NO tracking cookies
My website only uses functional cookies that are required to make it work correctly. There are no cookies that track your behaviour or invade your privacy. Exceptions are cookies used for ads and push notifications; see the sections “Push notifications” and “Advertisements” below.
NO location data
My apps will never store, share or transmit your location to other parties. Location data is not associated with any other personal or device data and is as imprecise as possible.
NO push notifications
My apps and websites do not send push notifications.
Advertisements
My apps that display ads make use of Google Mobile Ads. Google uses tracking to show personalised ads and track your use of these ads. To avert this, see below “Disabling tracking”.
Disabling tracking
Tracking for ads can be averted by enabling “Limit ad tracking” on your iPhone or iPads settings or enabling “Prevent cross-site tracking” on Safari on the Mac.
NO newsletters
I do not send newsletters or other promotional messages.
