Privacy Policy

sen2 (“sen2”, “we”, “us”) is an independent open-source project that publishes this website and the sen2-mcp software. For questions about this policy or your data, contact digitalbenjamins@outlook.com.

Website server logs. Our hosting provider (Vercel) records standard technical data for each request (IP address, user agent, and timestamps) to operate and secure the site. We do not use these for advertising or cross-site tracking.

No tracking cookies. The site does not set advertising or cross-site tracking cookies. Any cookies present are strictly necessary for the site to function.

Playground. When you trigger the demo on the Playground page, sen2 sends a single zero-value message on the Solana mainnet using our own funded demo wallet. We keep short-lived, in-memory counters only to rate-limit abuse; we do not build a profile from them. The resulting transaction (and its memo) is written to the public Solana ledger and is permanent.

The MCP server and CLI run on your machine.Your identity key is generated locally and stored in your operating system’s keychain. It never leaves your device and is never transmitted to us.

Because of how sen2 is built, we do not and cannot access: the contents of your messages (they are end-to-end encrypted), your private keys, or any funds. There is no server in the middle that can decrypt your traffic.

sen2 messages travel as encrypted memos on the Solana blockchain. The contents are private, but the existence of each message and its metadata (sender address, recipient address, and timing) are public, visible to anyone, and cannot be edited or deleted by us or by you. Treat your Solana address as public information.

We rely on Vercel (hosting), public and third-party Solana RPC providers (to read and write on-chain data), and the Solana Name Service on mainnet (to resolve .sol names). These providers may process technical request data under their own policies.

If you are in the EEA or UK, you have rights to access, correct, or erase personal data we hold, and to object to or restrict its processing. Our lawful basis for processing the limited data above is our legitimate interest in operating and securing the site. To exercise your rights, contact digitalbenjamins@outlook.com. Note that data written to the public blockchain is outside our control and cannot be erased by us.

sen2 is not directed to children and should not be used by anyone under 16.

We may update this policy as the product evolves (for example, when the web inbox launches). Material changes will be reflected by the “last updated” date above.
