We never keep your key.
This page is written to be read, not to protect us in court. If anything here is unclear, mail us and we will fix the wording.
What happens to a key you paste
It stays in the input box in your browser. When you press Check, your browser sends it to the vendor you are checking. OpenAI, Anthropic, Google, whoever it belongs to.
It does not travel to a server we own. There is no server. This site is static files.
What we do not do
- We do not write your key to a database, a file, or a log.
- We do not put it in localStorage, sessionStorage, or a cookie.
- We do not send it to an analytics tool.
- We do not email it, queue it, or cache it.
- We do not ask you to make an account.
Close the tab and the key is gone from this site forever. Reload the page and you start empty.
Check us
Open your browser dev tools, go to the Network tab, and press Check. Every request goes to a vendor domain. None goes to aicheck.in. The checker source is one readable file at assets/js/checker.js. Read it.
The optional proxy
Some vendors block calls made from a web page. If you turn on the local proxy, your key goes to the address you typed in that box, on your own machine, and on to the vendor. We do not host that proxy. We do not see it. If you point it at a stranger's server, that stranger sees your key. Point it at localhost.
What the site does collect
Standard web server access logs at the host: IP address, time, page requested, browser string. Those are for keeping the site up and stopping abuse. They never contain a key, because a key never reaches the server.
Ads and third parties
We plan to show ads to pay for hosting. An ad network sets its own cookies and may use your IP and page for ad selection. It has no access to the key field and no access to your check results. If you want none of that, use an ad blocker. We will not scold you.
Good habit
A key you paste anywhere is a key you should rotate when you are done. That is true here and true on every other checker. We would rather tell you that than pretend we are magic.
