The software developed by Sienna is free and not subject to any intellectual property claims from Sienna (see the licensing terms and conditions in the IP-section), but for information purposes only it can be stated that it also doesn’t collect any personal data from its users.

Sienna is committed to helping users understand the General Data Protection Regulation (GDPR) and California Consumer Privacy Act (CCPA) and similar in other parts of the world - but as stated above Sienna doesn’t collect any personal data and therefore doesn’t represent any services under these regulations. For this reason, Sienna doesn’t offer any Data Processing Agreement.

This is in opposition to the “AEC” approach – Privacy and Anonymity are distinctly different in spirit and objective. Sienna Network's DAO aim is to encourage and support development of regulatory compliant solutions as they are defined by the FATF.
