Privacy Policy

Effective 6 July 2026

linglo ("we", "us") is a translation and localization service at linglo.io. This policy explains what we collect, how we handle your documents, and the choices you have. Questions: [email protected].

1. What we collect

• Account data — your email address, an optional username, and your plan and usage counts (words — and pages, which only PDF translations use).
• Content you translate — the text you paste and the documents you upload, plus the translations we produce for you.
• Payment data — handled entirely by our payments provider, Dodo Payments. We never see or store your card details.
• Basic technical data — the minimum needed to run the service securely (e.g. your session, error logs). We do not use third-party advertising or cross-site tracking.

2. How we handle your documents

When you translate text or a document, we process it to deliver the translation and nothing else:

• Your file is stored on our infrastructure only for as long as needed to translate it.
• Its text and page images are sent to Google's Gemini API to perform the translation. We use a paid, billing-enabled Google tier under which Google does not use your content to train or improve its models, and content is not used for human review.
• We never use your documents or translations to train anything, and we never sell your data.

Where processing happens. To translate your content, we and Google run it on cloud infrastructure that may sit in different countries. Wherever it runs, the rule is the same: it's used only to produce your translation, never to train models, and it's deleted on the schedule below.

3. Retention & deletion

Uploaded documents and their translations are deleted within 24 hours. Your account data (email, username, plan, usage) is kept while your account is active; delete your account or email us and we will remove it. Your translation history is stored in your own browser, not on our servers, and clears when you clear it.

4. Bring-your-own-key (Lifetime)

On the Lifetime plan you can supply your own Google API key. On that path, your text is sent from your browser directly to Google using your key; we do not receive or process that content on our servers. Your key is stored only in your own browser.

5. Who helps us run linglo

We lean on a few trusted providers — chiefly Google, which performs the translation, and Dodo Payments, which handles payments as our Merchant of Record. A couple of others host the app and send your sign-in emails. None of them may use your content for anything but delivering linglo to you.

6. Cookies & local storage

We use the minimum needed to keep you signed in and remember your preferences (theme, language), stored in your browser. No advertising cookies, no third-party analytics that follow you around the web.

7. Security

Your connection to linglo is encrypted in transit (HTTPS). Access to your account requires a sign-in link or Google sign-in. No system is perfectly secure, but we keep our attack surface small and only collect what we need.

8. Your rights

You can access, export, correct, or delete your data at any time from your account or by emailing [email protected]. Depending on where you live (for example, in the EU/EEA under the GDPR), you may have additional rights, including the right to object to processing or to lodge a complaint with your local data protection authority.

9. Children

linglo is not directed to children under 16, and we do not knowingly collect their data.

10. Changes

If we make a material change to this policy we will update this page and its effective date, and where appropriate notify you by email.
