This policy applies to https://martstok.com and any related pages we operate. It does not apply to third-party services we link to.
We do not knowingly collect sensitive categories of personal information such as government identifiers, biometric data, or financial account numbers through this website. Payment details for active clients are collected and stored by our payment processors, never by us directly.
