4dayz privacy
Privacy Policy
This policy explains what information 4dayz processes to provide the service and operate it securely.
Effective date: 2026-07-06
1. Information We Process
4dayz may process posts, tags, public keys, signatures, request nonces, transmission times, IP-based security logs, and the minimum metadata needed for service operation.
2. Browser Keys and Local Storage
Private keys and passwords are managed in your browser. Saved keys may be encrypted with a password and stored locally, and the server cannot recover private keys or passwords.
3. Posts and Public Feed
Posts remain in the public feed for up to 96 hours. After removal, archived copies including content, tags, public keys, signatures, and related IP security logs may be retained for up to three months for operations, security, legal response, or failure recovery.
4. Encrypted DM
Encrypted DM bodies are designed so the server cannot directly read them. Metadata such as conversation information, participant public keys, ciphertext, key envelopes, signatures, and send times may be stored to provide the service.
5. Purposes of Use
Processed information is used to create and display posts, verify deletion permissions, deliver DMs, prevent abuse, apply rate limits, perform security audits, analyze failures, and comply with legal obligations.
6. Retention and Deletion
Archived posts and related IP logs are scheduled for deletion three months after archiving. Other security logs and operational metadata are retained only for the period required for service operation, security, or legal obligations and are then deleted or anonymized.
7. Third-Party Sharing
4dayz does not arbitrarily sell or share user information except where required by law, security incident response, or service infrastructure operation.
8. Contact
Questions about privacy processing may be submitted through the contact channels announced by the service operator.
