Privacy policy

Last updated 14 November 2026

Tayra Languages is a language-learning app for Android, iOS, macOS, Windows, Linux and the web, made by an independent developer (“we”). This policy says what the app and its sync service handle, where it goes and what you can do about it. Questions and requests: zavanton123@gmail.com.

Using the app without an account

Your books, lessons, words, flashcards, progress and settings are stored on your device, in the app's own storage. We receive none of it.

Some features fetch things from other services, which then see your IP address and what is asked for, under their own privacy policies:

• Translations and meanings: the word or sentence goes to the service you pick in the app: Wiktionary, MyMemory, or Google Cloud Translation with your own Google API key. Offline translation runs on your device.
• Example sentences and recordings: the word goes to Tatoeba, the Leipzig Corpora Collection (Wortschatz) or Wikimedia Commons.
• Courses, books, dictionaries, voices and app updates are downloaded from their publishers, mainly GitHub, and from the public libraries and news sites you choose to read from.
• Videos you watch in the app play from YouTube or from the address you added.

With an account

An account is optional. It keeps your library the same on all your devices. We keep:

• Your sign-in: your email address, and either a password, stored only as a salted hash, or the account identifier Google or Apple gives us when you sign in with them. From Google or Apple we receive your email address and that identifier, nothing else from your Google or Apple account.
• Your devices: each signed-in device's name and type (such as “Pixel 9, android”), when it signed in and was last used, and its sign-in token, stored only as a hash. You see and can sign out these devices in the app.
• Your synced library: the words you study with their status, translations and notes; flashcards and reviews; reading progress; texts and lessons you added; playlists and videos; which course and book packs you installed; and some settings.
• Subscription status, if you ever buy one: the store (Paddle, the App Store or Google Play) handles the payment and tells us only which plan you have and until when. We never see your card details.

We use your email only to sign you in and to send messages about your account, such as sign-in codes and password resets. No newsletters or marketing.

Where it is kept, and for how long

• The sync service and its database run on a server we rent from Contabo in the European Union, reached only over encrypted connections (HTTPS).
• The service logs each request: its time, address path, result and size, and the account it came from. These logs help us keep the service running and are deleted after 30 days. Your IP address is used only briefly, in memory, to limit abuse; the service does not log it.
• Once a day the database is backed up, encrypted with a key only we hold, to Backblaze B2 storage in the United States. Each backup is deleted after 7 days.
• Your account and synced library are kept until you delete your account. Deleting it removes them from the database at once; they leave the backups within 7 days and the logs within 30.

Who else handles it

Only the companies that run parts of the service for us: Contabo (the server), Backblaze (encrypted backups), Google and Apple (if you sign in with them) and the store that handles a purchase. We do not sell your data and do not share it with anyone else, unless the law requires us to.

Tayra Languages' use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

Your choices and rights

• Delete: in the app, Account → Delete account removes the account and everything synced to it. You can also ask us by email.
• See and take your data: everything synced is also on your devices, and the app exports it (backups, Anki decks and more). Ask us by email for a copy of what the service keeps.
• Correct: change your words, notes and settings in the app; ask us to change anything else.

Depending on where you live (for example the EU's GDPR or Brazil's LGPD), you may have further rights, such as to object or to complain to your data protection authority. We answer requests within 30 days.

The browser extension

Tayra for YouTube talks only to the Tayra app on your own computer and sends nothing to us. Its own privacy policy comes with it in the browser's extension store.

Children

Accounts are not meant for children under 13, and we do not knowingly keep data about them. If you believe a child has made an account, write to us and we will delete it.

Changes

When this policy changes, the new version is published here with a new date. Changes that matter for how your data is used are also announced in the app's release notes.
