Security Overview

How encryption works

Northern Wind uses end-to-end encryption so message content is encrypted on your device and decrypted only on the recipient device with the correct keys.

Message protection

Messages and call signaling are protected in transit with modern transport encryption, and message data is handled with strict access controls to reduce exposure risk.

Infrastructure security

Our website and systems use layered protections such as hardened security headers, controlled deployment access, network monitoring, and patch management practices.

Threat model

Northern Wind is designed to defend against common risks including network interception, credential abuse, and unauthorized data access, while continuously improving protections over time.

Responsible disclosure

If you discover a potential security issue, report it privately to privacy@northernwindapp.com with clear reproduction details. Please avoid public disclosure until reviewed.

• Include platform, app version, reproducible steps, and expected versus actual behavior.
• We target an initial acknowledgment within 72 hours for valid reports.
• For confirmed high-severity issues, we provide status updates as remediation progresses.
• See the incident communication page for how public notices are handled.
