My data

You sign in with a code sent to your email. Your collection and challenges are saved with your account and are private. Your collection data is not sold. Feedback you submit is stored with your account and the page you report, so the site administrator can investigate. Feedback includes a snapshot of your account and collection at the time of submission, visible only to the site administrator.

Cookies and browser storage

A cookie keeps you signed in. It lasts up to 30 days and is removed when you sign out. If you choose a language, it is remembered for one year. Your chosen appearance and country are also saved in this browser until you change them or clear browser storage. Your collection stays in your account, not in cookies. Audience measurement uses no cookie and no browser storage, and there is no advertising tracker.

Hosting and email providers process the information needed to run the site and deliver sign-in codes. You can choose your country to display regional release dates.

Audience measurement

Page views and loading speed are measured to show which pages are used and where the site is slow. It sets no cookie and stores nothing in this browser. Only the page address is sent; search terms and filters are removed first. The hosting provider counts visits with an identifier derived from the request that resets every day, so nothing follows you between days or to other sites. There is no advertising tracker and no profile.
