Privacy Policy

Last updated: 15 November 2026

In short: SnapLexi reads your screen only when you tap the bubble. To translate, the text you select (or the photo, if the phone can't read it) is sent to our server and on to DeepSeek, then discarded. Your saved words stay on your phone. We don't sell data or show ads.

What SnapLexi processes

Your screen, when you ask. After you allow screen capture, the app takes a screenshot only when you tap the floating bubble. Text is read on your phone with Google ML Kit. Screenshots are not uploaded.
Text to translate. The text you pick, and the languages, are sent to our server (hosted on Cloudflare) and on to DeepSeek to be translated.
Photos, sometimes. When you scan a photo or use the camera and the phone can't find text in it, the photo is sent the same way so DeepSeek can read and translate it.
Dictionary lookups. When you tap a word in the screen popup, that word and its language are sent to the Free Dictionary API.
Google sign-in (optional). If you sign in, we receive your Google account ID, name and email address to keep you signed in.
App check. To stop others misusing our server, the app uses Google Play Integrity to show it is the genuine SnapLexi app on a real device. This gives us a yes/no answer about the app and device, not personal data.
Usage records. For each request our server notes the time, type (text, photo, sign-in), whether it worked, how long it took, its size in tokens and its cost, plus a random device ID or your account ID. It does not store the text or photos.
On your phone only. Saved words, flashcard progress and settings are stored on your device and are not sent to us.

Who else handles it

DeepSeek translates text and reads photos. DeepSeek processes data on servers that may be outside your country, including in China, under its own privacy policy.
Cloudflare runs our server and stores the usage records.
Google provides ML Kit (on-device text reading), Play Integrity and sign-in.
Free Dictionary API provides word definitions.

We don't sell your data, use it for advertising, or share it beyond what's needed to run these features.

How long we keep it

Text and photos are passed through for translation and not kept by us. Usage records are kept for up to 12 months to run and protect the service. Data on your phone stays until you delete it in the app, clear the app's data, or uninstall it. Android may include it in your device backups, depending on your settings.

Your choices

Screen capture only happens when you turn scanning on and tap the bubble. You can turn it off any time.
Sign-in is optional; you can sign out in Settings.
To ask about or delete data linked to your account, use the contact details on our Google Play listing.

Children

SnapLexi isn't intended for children under 13, and we don't knowingly collect their information.

Security

Connections are encrypted (HTTPS), secrets stay on our server, and only the genuine app can use it. No system is perfectly secure, but we work to protect what we handle.

Changes

We'll update this page when things change and revise the date above.
