What happens to your files

When you translate a document, it travels over an encrypted connection to our processing service, gets translated, and comes back to you as a download. The text is sent to our translation model (Google Gemini) to do the actual translating. That’s the whole journey.

On the free bring-your-own-key path, your file never leaves your browser — only the text goes straight to the model with your own key, and we don’t see any of it.

What we store — and what we don’t

We store: your email (so you can sign in), your plan, and a counter of the words and pages you’ve used this month. That’s the list.

We don’t store: your source documents, your translations, or your content — beyond the short window needed to deliver your result.

We never train on your content

Your documents are not used to train any model — ours or anyone else’s. We call Google Gemini through its API, where submitted content isn’t used to improve Google’s models.

Who else is involved

We keep the toolbox small, and we’ll name everyone in it:

• Google Gemini — the translation model. Receives the text to be translated.
• Supabase — our accounts, database and temporary file storage (hosted in the EU).
• Lemon Squeezy — handles payments, so your card details never touch us.

We don’t sell your data, and we don’t share it with anyone outside this short list.

How long we keep things

Uploaded files and finished translations auto-delete within 24 hours — usually much sooner. Your account details stay until you delete your account, and then they’re gone for good.

Your choices

Delete your files, export your account data, or close your account entirely — all from your dashboard. Questions or requests? Write to hello@linglo.app and we’ll get back to you.

Cookies

The bare minimum: a cookie to keep you signed in, and your preferences (theme, language) saved in your own browser. No advertising trackers, no third-party analytics following you around the web.

If this ever changes

If we update this policy we’ll change the date at the top, and for anything that actually matters, we’ll email you.
