Privacy Policy
Last updated: 29 October 2026
Dictarium helps you learn languages from what you watch and read: you look up words in video subtitles and on web pages, save them to your own dictionaries and practise them. This policy explains what personal data we handle to make that work, why, who else sees it, and what you can do about it. It covers the Dictarium website (dictarium.space), the browser extension, and the Dictarium apps.
1. Who is responsible
The operator of Dictarium is Oleg Shulga, an individual (not a company), Russia ("we", "us"). You can reach us about anything in this policy at jktuiekmuf@gmail.com.
2. What we collect
Account. Your email address, username and a hash of your password (we never store the password itself). If you sign in with Google or Telegram, we receive the identifier of that account and, from Google, your email address. We also keep your interface language and the settings you choose.
What you build. The words, phrases, notes, tags, images and dictionaries you create or save, which of them are public, your practice results, learning statistics and streaks, bookmarks, and messages you send in features that have chat. Public dictionaries and your public profile are visible to other users.
What you look up. When you click a word or select text, the extension and the site send the selected text, a short piece of surrounding context (such as the subtitle line), the languages involved and, for video, the page address, video title and timecode, to our servers to produce a translation, a dictionary card or an explanation. When you save a video moment we store those details and, if you capture one, the screenshot of the frame.
Text recognition (OCR). Recognising text in a screen area runs on your device. The picture is not uploaded; only the recognised text is treated like any other text you look up.
Books and files. Files you add to the reader features (for example books) and your reading position are stored in your account so they sync between your devices.
Technical data. Your IP address, browser and device type, language and the pages or requests you make, kept in server logs and used to run, secure and debug the service. We also keep a session cookie so you stay signed in.
Visit statistics. On the website we record, with a random identifier stored in your browser, which pages are viewed, where the visit came from (for example a link or campaign) and whether it led to sign-up. This is measured by us, not by an advertising network. If you are not signed in, this identifier is not tied to you; once you sign in or register, it is linked to your account.
Automated visitors. Requests from search and AI crawlers are counted separately; for those we keep only a shortened IP address.
3. Why we use it
- to provide the service you asked for: your account, lookups, dictionaries, practice, sync (performing our agreement with you);
- to keep it safe and working: preventing abuse, finding and fixing errors (our legitimate interest);
- to send emails you need, such as a sign-up confirmation code (performing our agreement with you);
- to understand which pages and links bring people to the product and to improve it (our legitimate interest);
- to take payment if you buy a paid plan (performing our agreement with you; legal obligations).
Where the law requires your consent, such as ticking the box when you sign up, we rely on it, and you can withdraw it at any time. We do not sell your personal data and we do not use it for advertising by third parties.
4. Cookies and local storage
We use a session cookie to keep you signed in, and storage in your browser for your preferences and for the visit-statistics identifier described above. We do not use advertising cookies. You can clear this storage in your browser at any time; you will be signed out.
5. How long we keep it
We keep your account data while your account exists. When you ask us to delete your account, it is removed from our systems after a short grace period, apart from what we must keep by law. Server logs are kept only as long as needed for their purpose and then deleted. Words and dictionaries you made public may already have been seen by other users.
6. Your rights
Depending on where you live, you can ask us to give you a copy of your data, correct it, delete it, restrict or object to some uses, and withdraw consent you gave. You can change most of your data yourself in your account settings. To delete your account or to use any other right, write to jktuiekmuf@gmail.com and we will answer within one month. If you think we handled your data unlawfully, you can complain to your local data protection authority.
7. Children
Dictarium is not intended for children under 16, and we do not knowingly collect their data. If you believe a child has given us personal data, contact us and we will delete it.
8. Security
We protect data with encryption in transit, hashed passwords and restricted access for our staff. No system is perfectly secure, so we cannot guarantee absolute security.
9. Changes
We may update this policy. The date above shows the latest version. If a change is significant we will tell you in the product or by email, and where the law requires it, ask for your consent again.
