For every uploaded save file, GTASnP.com stores the uploader's IP address with the file information.
The reason for this is so that I (Samutz) can ban an IP address from uploading files if I determine that someone is trying to expoit or abuse this website or perform other malicious activities using this website.
The stored IP addresses are not sent to or viewed by anyone else and are never used for malicious purposes. I almost never view them myself unless something suspicious is going on.
When a save file expires (30 days after its last download), the IP addresses stored with it is automatically deleted along with the rest of the file information and the file itself.
A session cookie is set by the server and stored by your browser.
The cookie's purpose is to identify your session with the server, which is used for the Prefences you can use if you are a frequent user of the site.
The cookie and session information is not sent to or viewed by anyone else and are never used for malicious purposes.
The sessions do not store any identifying information other than the session ID found in the cookie and your IP address (see above).
Also like the IP addresses, sessions expire after 30 days of inactivity and are automatically removed from the server.
GTASnP.com is designed to be quick and simple to use and thus does not require registration or submission of any personal information to use. GTASnP.com is also ad-free.
