Cookies and browser storage
What the site stores in your browser, why, and why we don’t show a consent banner.
Last updated: 14 September 2026
In short
We don’t set any cookies ourselves and don’t use advertising or analytics trackers. The site stores only a few markers in your browser, without which progress and stars wouldn’t work. Third-party exercise services load only after you press a button.
What is stored in your browser
These are not cookies but browser storage (localStorage). The data stays on your device and never reaches us.
| Name | Purpose | How long it is kept |
|---|---|---|
lk.progress | Which lessons are completed, to show progress and stars | Until you delete it |
lk.blocks | Which topic parts are completed and the test result | Until you delete it |
lk.topbar.manager | That you closed the announcement bar (when there is one) | Until you delete it |
Our host, Cloudflare, may set strictly technical security cookies (for example
__cf_bm) to protect the site from bots. They are necessary for the site to work
and are not used for tracking.
Third-party services
- Quizlet flashcards in lessons and exercises from third-party services (such as Wordwall, LearningApps or YouTube) load only after you press “Show” or “Open”. The service then receives your IP address and may set its own cookies under its own policy.
- Links to Google Forms, Instagram, Facebook, Telegram and monobank open those companies’ websites, where their own cookie rules apply.
- Fonts are served from our own site, not from Google Fonts.
Statistics
There is currently no analytics on the site. If we turn it on, it will be Cloudflare Web Analytics, which uses no cookies and doesn’t track you across other sites. We will update this page before that happens.
Why there is no consent banner
Consent is required for cookies and similar technologies that aren’t necessary for the site to work (such as advertising or analytics). We don’t use any: progress markers are stored because you are using that feature, and third-party services load only after you act. If this changes, we will add a consent request.
