We do not want to collect information about people. We collect the absolute minimum required for the software to function and for the servers to operate. Nothing else.
KEIBIDROP transfers files directly between two devices over an encrypted peer-to-peer connection. Files never touch a server. The encryption key is negotiated between the two peers using ML-KEM-1024 + X25519 hybrid key exchange. No third party, including KEIBISOFT, can decrypt the transfer.
The application itself collects no personal data. No accounts, no sign-up, no email addresses, no analytics, no tracking, no telemetry. No cookies on this website.
Our web servers and relay servers produce standard access logs (nginx) that may contain IP addresses and timestamps. These logs exist for anti-abuse prevention and infrastructure operation. They are periodically rotated and deleted. We do not use these logs to identify or track users.
When two peers cannot connect directly, KEIBIDROP uses a relay for signaling and optionally a bridge for data forwarding.
The mobile apps include a "Send Logs" button that lets users share application logs with us for troubleshooting. This is entirely optional and user-initiated. Logs are never sent automatically. Before export, logs are sanitized to remove file paths, home directory names, and other personally identifiable information.
Users may opt into persistent identity and contacts. Both are stored encrypted on the device using keys from the OS keychain (macOS Keychain, Windows Credential Manager, Linux Secret Service, iOS Keychain, or Android Keystore). No identity or contact data is ever sent to KEIBISOFT or any third party.
When persistent identity is enabled, KEIBIDROP sends periodic heartbeats to the relay to indicate online status. The heartbeat contains a cryptographic token derived from the contact fingerprint. The relay cannot reverse the token to a fingerprint or identify the user. Presence data expires after 60 seconds.
KEIBIDROP is not directed at children under 13. We do not knowingly collect data from children.
KEIBIDROP does not integrate with any third-party analytics, advertising, or tracking services.
Since the application does not collect personal data, there is no personal data to access, correct, or delete. Server logs containing IP addresses are covered by our legitimate interest in operating the infrastructure and preventing abuse (GDPR Art. 6(1)(f)). If you have questions or requests, contact marius@keibisoft.com.
We may update this policy when adding new features. The date at the top of this page indicates the last revision.
