No cookies are set on visitors, and there are no third-party trackers or ad networks on these pages.
A small visit counter of our own counts page views, the site that sent you, the device type (phone or computer), the country, clicks on Google Play buttons, and which demos, tools and Blinq tricks get used (for the photo privacy check, only that a photo was checked or cleaned, never anything from the photo). It keeps no IP addresses: a visitor is recognised within one day by a code made with a key that is deleted the next day, and the country is looked up from the address in memory. The site that sent you is remembered in your browser tab until you close it, so a later Google Play click can be counted against it; it is not a cookie.
The video on the looks page comes from YouTube's privacy-enhanced player and loads only when you press play.
Google Play buttons take you to Google Play, where Google's own privacy policy applies.
