Privacy Policy

Please read this Privacy Policy carefully to understand how data is collected, handled, and recorded when using the Linez Protocol and its interface.

1. Public Blockchain Disclosures

1.1 Permanent Public Ledger: Linez Protocol is built on public blockchain networks (primarily Solana). All transactions, escrow deposits, acceptance states, collateral locks, evidence graph hashes, presence attestations, and mutual cancellations are recorded permanently on the public blockchain.

1.2 No Deletion (Right to be Forgotten): Data written to a public blockchain is immutable and cannot be modified, anonymized, or deleted. By interacting with the protocol, you accept that your wallet address, transaction history, and hashed evidence graph parameters are publicly visible and permanent. We accept no responsibility or liability for any consequences arising from the permanent public nature of blockchain records.

2. Information We Collect (Off-Chain)

2.1 Waitlist Registrations: When applying to join our waitlist, we collect your name, email address, phone number (optional), and waitlist interest (Seeker, Traveler, Venue, Developer).

2.2 App Metadata: During alpha and devnet testing, the client application may collect off-chain metadata (such as encrypted message histories, device diagnostic reports, and Turnstile security tokens) to enable coordination and protect against bot attacks.

3. Location and Presence Data

3.1 GPS and Proximity Signals: While active in a meetup, the client app utilizes GPS signals to verify proximity alerts and calculate venue proximity. This data remains on-device or is hashed before transmission.

3.2 Hashing of Meetup Windows: To protect user privacy, details such as the exact meetup start and end times are hashed client-side with a unique cryptographic nonce. Only the sha256 hash is committed to the blockchain, ensuring observers cannot inspect your physical meetup schedule until check-in is revealed at the venue.

4. Data Security and Third Parties

4.1 Disputesnapshots: In the event of an active dispute, an encrypted snapshot of the order's off-chain chat transcripts may be frozen and accessed by verified reviewers/jurors. Reviewers are bound by community rules to use this data strictly for arbitration.

4.2 Zero Liability for Breaches: While we employ strict encryption and data isolation procedures for off-chain metadata, no internet-based transmission or storage system is entirely secure. We accept no liability or responsibility for unauthorized data access, server hacks, database leaks, or third-party breaches.

5. Changes to This Policy

5.1 We may modify this Privacy Policy from time to time as protocol development progresses. Continued use of the website or waitlist constitutes acceptance of the updated policy.
