TenWords privacy

Last updated: August 6, 2026.

What TenWords does with your data

When you condense a page, the text of that page's paragraphs is sent to one of two places, depending on how you configured the extension: directly to Anthropic's API (if you saved an API key in the extension options), or to a TenWords service running on your own machine at localhost:4710. In both cases the text is sent only to produce the summaries, and TenWords keeps no copy.

What we collect

Nothing. TenWords has no servers, no accounts, no analytics, no telemetry, and no tracking of any kind. We never see your key, your pages, or your summaries.

Your API key

The Anthropic API key you save in the options page is stored with chrome.storage.local in your browser profile on your machine. It is never synced, and it is sent only to api.anthropic.com as the authentication header on summarization requests. Removing the key in the options page deletes it.

Third parties

Text you condense in direct mode is processed by Anthropic under their privacy policy. TenWords sends nothing to anyone else.
