Language Harbor: privacy policy

Agent Harbor LLC, Bremerton, Washington, USA. Contact: support@agentharbor.agency. Last updated: 2 November 2026. This policy covers Language Harbor version 0.1, the desktop browser extension. Plain language, not legal advice.

Short version: Language Harbor translates on your device. It does not send what you read, the pages you visit or your saved words to Agent Harbor or to anyone else. There is no account, no analytics and no telemetry.

What the extension does with the pages you visit

  • When you turn it on for a page, it reads the page's text so it can show each paragraph in your second language, stacked with the original.
  • The translation is done by the translator built into your browser (Chrome's on-device Translator). Language Harbor does not send page text anywhere itself. Your browser may download its language model the first time you use a language pair; that download comes from your browser's maker under its own terms (see Google's privacy policy for Chrome).
  • The translated text is added to the page, so the page's own scripts can see it, just as they can see any other text on the page.

What we keep on your device

These are stored in the browser's extension storage on your computer and are removed when you uninstall the extension:

  • Your settings: language pair, stage, how the second line looks, and which sites it is on or off for.
  • The words you save, with their meaning and whether you are still learning them.
  • Reading progress per language pair: counts per session (date, stage, how many hidden lines you revealed). Not which text you read.
  • Today's count of translated pages, stored as short codes made from the page address, not the addresses themselves. It is replaced each day.
  • The date you last changed language pair.
  • Whether it is on in each open tab. The browser clears this when the tab closes.

What leaves your device

Nothing. This version has no server, makes no network requests, has no analytics or crash reporting and loads no remote code. If a later version adds anything that would send data (for example a paid plan), this policy will be updated with its date before that version is published, and the store listing will say so.

Deleting your data

Uninstall the extension. The browser removes everything listed above. There is no copy anywhere else to delete.

Permissions

The extension asks only for storage permission. It reads the pages you use it on so it can show them in two languages, and it does not send any of that anywhere.

Children

The extension is a general-purpose reading tool and does not collect data from anyone, including children.

Changes and contact

If this policy changes, the new version is published on this page with its date. Questions: support@agentharbor.agency.

AI assistance disclosure: this extension's code and this text were written with AI assistance. The extension uses your browser's built-in translator and contacts no AI service of ours.
