✶ Win32 client in C
Global system hook that restores window visibility for whitelisted processes, shipped as a single signed installer with no runtime dependencies.
✶ Signed licensing with device binding
ECDSA P-256 license validation tied to a hardware fingerprint, plus SHA-256 checksum verification so a leaked key can't run elsewhere and tampered binaries refuse to start.
✶ Serverless backend on Cloudflare
Workers + D1 handle the full Stripe subscription lifecycle (active, trial, grace period, canceled), provisioning and emailing license keys within seconds of payment.
✶ Automated Windows builds
GitHub Actions cross-compiles on every tagged release and feeds the artifact's hash into the license server, making updates safe to ship.
