Account, subscription, and usage data are used to operate the service, secure access, and manage billing. If you register, PatternLedger saves the source, campaign, content, and partner code connected to that signup. To measure website reach, the site also counts browser visits to public pages using a random, short-lived value in session storage. Visit records contain a hashed value, time, public page path, and broad source group. They do not contain your email, raw IP address, search terms, or full referring URL. This measurement does not use a third-party advertising tracker. The visit counter respects browser Do Not Track and Global Privacy Control signals. It is an estimate, not a count of identified people.
