The standing boundary
Support never logs into your accounts, remotely controls a device, or makes changes to your systems. It may help with product fit, files, delivery, subscriptions, entitlements, payment reconciliation, refunds, licenses, privacy, and security reports. Support never requests or accepts a password, API key, seed phrase, private key, wallet backup, PIN, QR payload, card number, or payment credential. Transaction ids and screenshots may help locate a case but never prove identity or settlement by themselves.
Reporting a security issue
Found a vulnerability or security concern? Email support@signalharness.ai — the disclosure contact listed in /.well-known/security.txt. We acknowledge receipt and will never ask you for passwords, keys, seed phrases, or payment credentials.
Self-serve first
Most setup questions are answered inside the kits: every product ships its own FAQ.md and QUICK-START.md, plus an integration pack with a compatibility matrix, known conflicts, a safe-install checklist, and a complete rollback guide.
