Privacy Notice

v1.0

“Your confession is public. Your profile doesn’t have to be.”

1. No Public Profiles or Third-Party Tracking

Confession Booth is fundamentally engineered so anyone can express themselves without exposing a public identity. Our feed does not disclose wallet addresses, centralized user IDs, user IP addresses, or covert telemetry logs.

2. Zero-Knowledge Cryptography (ZK Stealth)

In ZK Stealth mode, membership proofs are generated locally within your browser using cryptographic Merkle Proof and Epoch Nullifier algorithms. The submission payload is transmitted to the backend server without authentication headers or session tokens, making it mathematically impossible for the server to correlate the confession with the author’s wallet address.

3. Honest Privacy Boundaries

We never promise absolute or magical anonymity. Blockchain transaction histories, RPC/network metadata, and behavioral patterns can still create correlation risks.

Whispers & reactions are pseudonymous, not zero-knowledge: they are sent under your session and stay linkable on the server, even though the public sees only anonymous names.
OP badges shrink the anonymity set: replies marked as the original poster reveal authorship correlation to observers.
Content hashes are deterministic: very short confessions could be brute-forced by anyone comparing hashes.

Important Warning: Never write names, locations, phone numbers, or unique details that could easily identify you or someone else.

4. Immutable Blockchain Records

Every confession is permanently anchored via canonical cryptographic digest (SHA-256) on the Ethereum Sepolia network. While the moderation team can quarantine violations from the public app feed, published blockchain transaction hashes are permanent and cannot be retroactively erased.
