Notice and choices
“Understood” dismisses an informational notice. It does not accept personal data processing, the offer or advertising. There are currently no optional cookie categories, so no “Accept all” choice is offered for advertising tracking.
Browser settings can restrict or clear cookies and local storage. Without the account cookie, sign-in will not persist. Clearing local storage may remove the only copy of a series or an order key; first export CSV/JSON and save the private link. Removing a browser copy does not delete a server project.
The “Browser storage” footer item reopens the notice. If analytics or advertising are introduced, the policy and choice mechanism must be changed before those scripts run.
External pages
Payment pages, Telegram and scientific sources may use their own cookies when visited separately. Their actions follow their own rules. The current service interface does not install their trackers.
