Privacy Policy

Last updated: 2026-10

Sergio Taratorin operates LexiReader. This policy explains what we collect and why.

What we collect

• Account data: name, email and password hash, or your Telegram ID, name and username if you sign in with Telegram.
• Learning data: books you import, saved words, reviews, reading time and settings.
• Payment data: plan, amount, date and the payment provider's transaction ID. Card details are handled by YooKassa or Telegram and never reach us.

Services we use

• Anthropic (AI explanations): the selected word or sentence, the book title and your follow-up questions.
• YooKassa and Telegram (payments, sign-in, bot messages).
• Dictionary and translation services (dictionaryapi.dev, Wiktionary, MyMemory, DeepL, Google, Yandex): the word or phrase you look up.
• Google Cloud speech (where your browser can't speak or listen, e.g. inside Telegram): the word or sentence to read aloud, and a few-second recording when you practise pronunciation. Recordings aren't stored by us.
• Advertising (free plan only, if enabled): advertising networks such as Yandex or Google may use cookies to show ads.

Your rights

You can export your words (Word bank → Export) and delete your account and all of its data at any time in Settings. For other requests, contact Telegram @LexiReader_bot.

Retention

We keep your data while your account exists. Payment records are kept as long as the law requires.
