Privacy Policy

What data we receive

When you start Langify via Telegram, the service stores your Telegram user ID, username, first name, last name if available, Telegram interface language, selected app locale, study language, native language, a technical Telegram Premium flag, and profile creation and update timestamps.

To operate your vocabulary and flashcards, the service stores card content such as the word or phrase, normalized form, translation, example, example translation, transcription, part of speech, synonyms, collocations, note, original input, card language, card status, spaced repetition fields and timestamps.

Usage data created while you study

If the language of a new card cannot be detected with enough confidence, a temporary pending import is stored until you choose the language. After that, the pending object is either used to create the card or removed.

For repetition and stats, Langify stores review events such as rating, interval before and after review, ease factor and review date.

To enforce limits on new words, the service stores word usage events showing whether a card used free quota, paid credits or unlimited access.

Payments

Payments inside Telegram use Telegram Stars. Langify does not store bank card details and does not process your card data directly.

To confirm paid access, the service stores only technical payment data: product, Stars amount, granted credits or access tier, invoice payload, Telegram payment charge ID, provider payment charge ID if present, and payment date.

Why the data is used

The data is used for Telegram sign-in, interface language selection, card creation, automatic card enrichment, spaced repetition, statistics, limit management, payment-based access restoration and support requests.

Third-party services

Some functions may send limited data to external providers required for the request, including Telegram for authentication and payments, and language services used for language detection or automatic card filling.

Storage period and deletion

User data is stored while it is needed to keep the account, cards and access working. Users can clear cards and reset progress in the product, and they can also request account and related data deletion through support.

Data requests and deletion requests can be sent to support@langify.tech.
