Open any page here and then look at your browser storage. Empty. These 99Exch pages never write a cookie, and no analytics tag or ad network script sits in the code to note which link you pressed, how long you stayed or what search brought you in.
Keep the network tab open while this privacy policy loads and every font file you see is fetched from 99exch-login.com/fonts/, the address that served the page itself, which means the 99Exch typeface adds no outside request at all.
One limit, so it is clear. This policy stops at our own pages. Once you press through to the official 99Exch login screen, that screen runs under its own rules, and it carries a reCAPTCHA line saying the Google Privacy Policy and Terms of Service apply there (we cannot speak for anything past that point). Our terms-and-conditions page sets out how this site itself may be used.
