Privacy
Short version: no cookies, no tracking, no account. We don't try to find out who you are. Here are the details.
No cookies, no tracking
Czech Grammar doesn't use cookies, ads or analytics tools. Nothing on this site follows you around the web, so there's no cookie banner to click away.
What's saved on your device
The app saves two things in your own browser, and nothing else:
- Your progress: your best score for each topic, the sentences saved in My mistakes and whether you've closed the welcome message (in your browser's local storage).
- An offline copy of the app, so it keeps working without internet.
This stays on your device. It's never sent to us or anyone else. Because it's only there to give you the service you're using, it doesn't need your consent. To delete it, use Reset my progress on the How to use page, or clear this site's data in your browser settings.
When you visit the website
Like every website, ours runs on the servers of a hosting provider, Cloudflare. To send you a page, the server receives the usual technical information: your IP address, the date and time, the page you asked for and your browser type. The provider may keep this in short technical logs to keep the site secure and working, and deletes it after a short time. We use it for nothing else.
When you write to us
You can email us or use the forms on this site: Suggestions and Report a problem in the exercises. With a form, we receive your message, the page or exercise it's about (with your answer, if you report an exercise), the language of the site, whether you're a student or a teacher (if you say) and, only if you give it, your email address. The form sends this to our email inbox through Cloudflare. It doesn't save your IP address. If you email us, we receive your email address, your name if you include it, and your message.
We use these messages only to fix and improve the app and to reply to you. We keep them for 12 months after our last message, then we delete them.
Who else sees this data
Only the services we need to run the site: our hosting provider Cloudflare (for the technical data above) and Google, because our email is a Gmail account. They process it on our behalf. We never sell or share your data with anyone else. If any of this data is processed outside the EU, it's only with the safeguards the GDPR requires, such as an EU adequacy decision or standard contractual clauses.
Google Search
We use Google Search Console to see how people find the site in Google search results. It doesn't add any code or cookies to this website.
Your rights
You can ask us to see, correct or delete the personal data we have about you, to limit how we use it, or object to it. Just email us. You also have the right to complain to the Czech data protection authority, Úřad pro ochranu osobních údajů (ÚOOÚ).
Links to other sites
Some pages link to other websites, such as the official exam site or our Instagram. Their own privacy rules apply there.
