Cookie Policy
We use only the cookies needed to keep you signed in and to keep the site secure. No advertising cookies, and nothing that identifies you or follows you off this site.

The short version
Langova does not track you. There is no Google Analytics, no advertising pixel, and no third-party script that follows you around the web. The cookies below exist so the site can remember that you are signed in and reject forged requests. Because they are strictly necessary to provide a service you asked for, no consent banner is required — and that is why you have not seen one.
We do count visits and measure how fast pages load, using two scripts from Vercel described below. Neither sets a cookie, stores anything in your browser, or can tell who you are — which is why they do not change the answer above.
Cookies we set
| Cookie | Purpose | Expires |
|---|---|---|
| Session token next-auth.session-token | Keeps you signed in. Without it every page would ask you to log in again. | 30 days, or when you sign out |
| CSRF token next-auth.csrf-token | Proves a sign-in or form submission genuinely came from you, not from another site acting in your name. | When you close the browser |
| Callback URL next-auth.callback-url | Returns you to the page you were on after signing in. | When you close the browser |
Things stored in your browser that are not cookies
These sit in your browser’s local storage. They never leave your device and are never sent to us:
- Your recent exam results, so the exams page can show them immediately rather than waiting on a request.
- Which passages you have already seen, so a new exam does not repeat one.
- Whether you dismissed the “confirm your email” notice, so it stays hidden for a week instead of reappearing on every page.
Clearing your browser data removes all of these. Nothing breaks; the pages refetch.
Counting visits and measuring speed
Two scripts from Vercel, who host this site, run on every page:
- Web Analytics — counts page views so we know which pages are used. To tell one visitor from another without a cookie, it takes the page you requested, your browser type and your rough location, and hashes them with a secret that is thrown away and replaced every day. The result cannot be reversed, cannot be matched to your account, and cannot be linked to yesterday’s visit or tomorrow’s.
- Speed Insights — reports how long the page took to become visible and usable on your device, so slow pages get found and fixed. It sends timings and the page address. That is all it sends.
Neither script stores anything on your device, sees your exam answers, essays or recordings, or shares data with an advertising network. Vercel publishes the full detail in its analytics privacy statement. Blocking them in your browser or with an ad blocker costs you nothing — the site works exactly the same.
Third parties
Two services may set their own cookies when you actually use them, not merely by visiting the site:
- Stripe — when you reach checkout, for payment processing and fraud prevention.
- Daily.co — when you join a live class, to run the video call.
Embedded lesson videos are served from YouTube in no-cookie mode and from Vimeo, so watching one does not add you to an advertising profile.
Turning cookies off
You can block or delete cookies in your browser settings. Blocking the session cookie means you will not be able to sign in — there is no way around that, since being signed in is what the cookie records.
