Domain Canary

Domain Canary watches SSL certificates and domain registration dates so renewals don’t catch you off guard.

Add the hostnames you care about. The app checks certificates with a real TLS handshake and looks up domain expiry through public RDAP when available. Prefer your own dates? Set a manual override anytime. Everything stays on your device—no account, no cloud sync to SudoCod, no ads, and no analytics SDK.

WHO IT’S FOR
• Freelancers and indie builders managing a handful of sites
• Small teams who want a simple phone-side expiry checklist
• Anyone who prefers pay once and keep data local over another subscription monitor

WHAT YOU GET
• Hybrid checks — SSL via live TLS + domain expiry via RDAP
• Urgency dashboard — filter Critical, Soon, or Healthy
• Certificate details — issuer, subject, SANs, valid-from, TLS version
• Domain details — registrar, registered/updated dates, status, name servers
• Local reminders — configurable thresholds (default 30 / 14 / 7 / 1 days)
• Backup — Android Auto Backup plus JSON export/import
• Tablet layout — two-pane view on wide landscape screens

HOW IT WORKS
1. Add a hostname (optional notes)
2. Auto-check SSL and domain expiry—or enter dates yourself
3. Get reminded before certificates or domains expire

PRIVACY, SIMPLY
• No login required
• Your tracked list stays on the device
• Network is used only for checks you run: TLS to your hosts and public RDAP lookups
• Backups are under your control (system backup and/or files you export)
• Full policy: see the Privacy Policy link on this listing
