Cookies
Version 2026-08-24.
The short answer
We use no analytics, marketing or tracking cookies. That is why there is no consent banner — there is nothing to consent to.
We embed no third-party analytics, no social media buttons and no advertising pixels. We build no profiles and sell no data about what you browse.
What we store in your browser
The Service uses browser local storage (localStorage) rather than classic cookies. We
store two things there:
| What | Purpose | How long | Consent required | | :---- | :---- | :---- | :---- | | Session token | Keeping you signed in. Without it you would enter your password on every click | Until sign-out or session expiry | No — strictly necessary for the service you requested | | Selected interface language | Remembering your language between visits | Until you delete it | No — a setting you chose yourself |
Both entries live only in your browser. They do not reach our server other than as the session token attached to requests you make deliberately anyway (for example opening your account panel).
Why no consent is needed
The ePrivacy Directive (and Article 173 of the Polish Telecommunications Law implementing it) requires consent for storing information on a user's device except where it is strictly necessary to provide a service explicitly requested by the user.
The session token is exactly that exception: without it there is no way to keep the sign-in the user asked for by signing in. Remembering the language is a setting the user chose in the language switcher.
How to remove it
In your browser settings, under site data ("Clear browsing data" / "Site settings"). The effect is being signed out and returning to the default language. Nothing else disappears — your account, tokens and worksheets live on the server, not in the browser.
If this changes
If we ever add a tool that requires consent — analytics, advertising, embedded third-party content — a separate request will appear before it runs, and this document will be updated along with its version date.
