What we keep, and why.

You sign in with an email address. We keep it to sign you in and to send receipts.

Payments are handled by Stripe. We do not see or store your card number.

The checks you run are private to you. Other users cannot see which links you checked.

Text you paste to check stays private to your account. It is never published, never indexed by search engines, and its claims are not shared with other users' checks.

A check becomes public only if an editor publishes it. You can ask for publication. We do not publish your name with it.

The extension stores the account key you approve on polygraphs.xyz in your browser, and sends it only to Polygraph. Each browser you connect gets its own key.

While its side panel is open, it sends the address of the page you are viewing — a post, an article or any other web page — to Polygraph, to find that page's check. It sees addresses only while the panel is open, and runs no scripts on the sites you visit.

It sends text you have selected only when you choose “Check with Polygraph” from the right-click menu, or paste text into the panel yourself. A check is sent only when you press Check and confirm the price.

Disconnect it from the panel, or revoke its key from your account, and the key stops working at once.

Published pages show claims, verdicts and sources. They show the public author of a public post. They do not profile people.

Polygraph is for adults. We do not knowingly collect information from anyone under 18. If you think a child has made an account, write to us and we will delete it.
