Privacy Policy

For the Fact-Check — YouTube & articles browser extension. Last updated 30 June 2026.

Fact-Check is a browser extension that checks the claims in the YouTube video or web article you are viewing, using an AI model you configure. This policy explains exactly what the extension accesses, where that data goes, and what we do — and do not — collect. In short: the extension only acts when you click it, it stores your settings on your own device, and we run no analytics, ads, or tracking.

What the extension processes

Page content and video transcripts

When you click Fact-check on a YouTube video or an article, the extension reads that page's text (for articles) or the video's transcript (for YouTube) and sends it to two places so the check can run:

• the AI provider you have chosen in settings — OpenAI, Google, or Anthropic — which generates the verdicts; and
• our caching service (see below), so the same video or article does not have to be re-checked later.

This only happens for the specific page you act on, and only when you click. The extension does not read pages in the background.

Your AI provider API key

You provide your own API key for your chosen AI provider. It is stored locally in your browser (chrome.storage.local) and is sent only to that provider's API to authorize your own requests. We never receive, see, or store your API key.

Cached results

To make repeat checks instant and free, the extension caches results. The cache is keyed by the YouTube video id, or by a hash of an article's URL and text. Results are stored locally in your browser and also in a shared cache we operate (a Cloudflare D1 database). Because the shared cache is common to all users of the extension, cached verdicts — and, for videos, the transcript — may be readable by other users who check the same public video or article. Do not fact-check private, internal, or sensitive pages if you do not want the result cached. The cache stores the page text/transcript and the AI's verdicts; it does not store your identity, your API key, or any account information.

What we do not collect

• No accounts, names, emails, or other personal identifiers.
• No analytics, telemetry, advertising, or browsing-history tracking.
• We do not sell or transfer your data to third parties, and we do not use it for anything unrelated to fact-checking the page you asked about.

Third parties

Page text/transcripts are processed by the AI provider you select and by our cache host. Their handling of that data is governed by their own policies:

• OpenAI Privacy Policy
• Google Privacy Policy (Gemini API)
• Anthropic Privacy Policy
• Cloudflare Privacy Policy (cache hosting)

Permissions, and why they are needed

• storage — save your provider choice, API key, and cached verdicts on your device.
• activeTab and scripting — add the fact-check UI and read the article or transcript, only on the tab you click.
• Host access to your AI provider's API and to YouTube — to fetch the transcript and run the check. The extension also contacts the shared cache service.

Retaining and deleting data

Local data (your key, settings, and local cache) is removed when you clear the extension's storage or uninstall it. To request removal of a specific entry from the shared cache, email us.
