CertWatch: SSL/TLS Certificate

CertWatch is a professional, privacy-first utility designed for system administrators, web developers, and security enthusiasts who need to keep a close eye on their SSL/TLS certificates without compromising data privacy.

Unlike other monitoring services, CertWatch is 100% local. It performs all certificate handshakes and data storage directly on your device. No accounts, no cloud servers, and no telemetry.

KEY FEATURES:

• Automated Monitoring: Add any hostname or HTTPS URL to start tracking. CertWatch periodically checks the certificate status in the background.
• Expiry Alerts: Get notified before your certificates expire. Choose your monitoring interval to balance between battery life and frequency.
• Deep Certificate Analysis: View detailed information including Subject, Issuer, SHA-256 fingerprints, and SPKI hashes.
• Certificate Chain Viewer: Inspect the full trust chain from the leaf certificate to the root-adjacent intermediate CA.
• Change Detection: CertWatch records snapshots of every check. If a certificate is renewed or changed unexpectedly, you'll see it in the history timeline.
• Privacy by Design: Your monitored list and certificate history never leave your device. All TLS handshakes are performed locally via your device's network.
• Export/Import: Easily backup your monitored list to a JSON file or clipboard to move it between devices securely.
