# The Privacy Engine Signet operates on a privacy-by-design methodology. We do not retroactively anonymize data; we collect it anonymously at the source. This architecture eliminates the need for consent banners and compliance overhead. #### Session Deduplication Without Cookies Traditional analytics rely on placing a cookie on the user's device to track them across sessions and days. Signet eliminates this requirement entirely. Instead, we utilize a privacy-preserving hashing mechanism to define a unique session. When a request is received, we generate a hash based on the user's IP address, User Agent, and a daily rotating salt. This hash allows us to identify that a sequence of page views belongs to the same visitor session. Crucially, because the salt is discarded and regenerated every 24 hours, the hash is mathematically irreversible and strictly temporary. It is impossible to reconstruct a user's activity history beyond a single day, ensuring that no long-term user profiles can be built. #### Compliance Automation By ensuring that no Personally Identifiable Information is ever stored on our servers or the user's device, Signet bypasses the regulatory triggers for GDPR, CCPA, and PECR. You do not need to display a cookie consent banner because there are no cookies to consent to. You do not need to manage data deletion requests because we do not hold data that can be linked to an individual. Compliance is not a setting you configure; it is the default state of the infrastructure. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
