"B-but, this is definitely an IP grabber!!!!"
This website is NOT an IP grabber. I do NOT store any IP addresses. IP addresses are only being collected to check the security of connection.
Stop being paranoid about your IP address going to leak your location. IP addresses can only show the city/state name at max. And this is usually not even accurate. People can't find you with IP addresses.
The algorithm of the security check is; the website checks your browser's local storage to see if you have the trusted key. If you don't have that or your IP address is changed recently or trusted key is older than 3 hours system collects your IP address with an API and then sends this IP address to a different API to see if your IP address is suspicious or not. Then by the result system writes the trusted key to local storage or sends you to "blocked" page. While these happens IP addreses is only stored in your browser, not in a server.
This website is open-source, meaning you can inspect the code. Or just ask ChatGPT to inspect the repo.
