Monitors your emails, domains, and passwords for data breaches and DNS changes — all checks run locally and privately

Canary periodically checks if your email addresses, domains, or passwords have appeared in data breaches using the Have I Been Pwned API with k-anonymity (your full data never leaves your Mac). Monitor DNS records for your domains and get alerts if they change — potential signs of hijacking. Passwords are stored as SHA-1 hashes only, never in plain text. Encrypted SQLite stores all results. Status at a glance: green (all clear), yellow (new finding), red (critical breach). Export a full PDF report of all findings.
