Privacy policy

Updated: September 25, 2026

Draft: this text must be reviewed by a lawyer before publication.

1. What data we store

Your e-mail (for code sign-in), name, UI language and native language, the contents of your dictionaries (words, translations, examples and your edits), and technical session data: device, IP address and last sign-in time.

2. How we use it

Only to run the service: sign-in, syncing dictionaries between devices, teacher access to a student's dictionary at your invitation, and sending sign-in codes. We do not sell or share data with third parties for advertising.

3. AI processing

The word you enter is sent to a language-model provider to build the card; example sentences are sent to a speech-synthesis service. Personal data (e-mail, name) is not sent to providers.

4. The shared word base

Word cards (translations, examples, pronunciation) are stored in a shared base used by everyone learning the same language. Nothing you type yourself enters the shared base: your edits stay in your dictionary only.

5. Storage and deletion

Data is stored on servers in the EU. You can end any session in the settings. To delete your account, write to us — it will be deleted together with the dictionaries.

6. Cookies

We use only technically necessary cookies: the sign-in session and the chosen site language. There are no advertising or analytics trackers.
