1. What This Page Covers
This page explains how 140 Brain Challenges uses cookies and similar technologies, including localStorage, which the application uses for some tasks instead of cookies.
2. Strictly Necessary
These are technical elements the application needs in order to work, such as storing the signed-in session for registered users. They do not require consent because the requested function would not be possible without them.
3. Analytics — Only With Consent
If you click Accept, the application stores a random session identifier in localStorage and records which cards and filters you use. For signed-in users, records are linked to the account so we can count active users. Records are kept for 24 months. If you choose Decline or make no choice, none of this happens and the identifier is not created.
4. No Advertising or Third-Party Tracking
There are no advertising or social-media trackers, and behavioural data is not passed to advertisers.
5. Managing Your Choice
You can change your decision at any time below, in the section on this page, and by clearing site data through your browser. Withdrawing consent deletes the session identifier.
