The public directory does not require an account. Favorites stay in your browser and are not sent to the server.
For operational statistics, the site may store a short-lived pseudonymous session hash, visited path, device class, coarse country code, referring host, active-session signals and model or affiliate interactions. Raw IP addresses are not written to the analytics database.
Contact submissions are stored only for handling the request and are removed under the configured retention schedule. They are never sold.
