โ ๏ธ Note: We donโt save CAPTCHA results. If you are presented with email or SMS verification, we only save a cryptographic hash of your email or phone number which is not permanently associated with the account. Because hash functions are one-way functions, it is impossible to derive your phone number or email from that hash. However, using the same phone number will result in obtaining the same cryptographic hash. So by comparing hashes, we can detect if phone numbers or email addresses are reused for human verification.
