Policy
Privacy Policy
Effective date: May 22, 2026. This policy explains how Masse Labs handles information across our website and privacy-preserving verification products.
1. Who we are
Masse Labs builds ZKProofport, OpenStoa, and related developer infrastructure for privacy-preserving verification using zero-knowledge proofs.
2. Information we collect on this website
Our public website is designed to be informational. We do not require visitors to create an account to browse masselabs.com. If you email us, we process the contact details and message content you provide so we can respond.
3. ZKProofport mobile app
ZKProofport is designed so proof generation happens locally on the user's device whenever supported. Proof inputs, identity details, and credential source data are not collected by Masse Labs as part of local proof generation. Completed proofs may be transmitted only when the user approves a proof request.
4. OpenStoa and developer services
OpenStoa and developer services may process account, session, proof verification, request, or usage metadata required to operate the service, prevent abuse, provide support, and maintain security. Where possible, we use nullifiers and cryptographic outputs instead of raw identity data.
5. Service providers
We may use infrastructure, hosting, wallet, authentication, analytics, email, or cloud service providers to operate our products. These providers process information only as needed to provide their services to us.
6. Security
We use technical and organizational measures appropriate for the nature of the data we process, including encryption in transit, limited access, and privacy-preserving architecture. No internet service can be guaranteed to be perfectly secure.
7. Your choices
You may contact us to request access, correction, deletion, or restriction of personal information that Masse Labs controls, subject to applicable law and security requirements.
