No. Every tool runs entirely on your device. The app has no analytics, no accounts, no ads, and no third-party dependencies. Text you paste, keys you generate, and secrets you store never leave your Mac or iPhone.
In the system Keychain on your own device — not in the app and not in the cloud. Each secret is guarded by the protection you pick: none, device passcode, or Face ID / Touch ID. Values stay encrypted until you explicitly tap Reveal. Deleting the app removes its stored secrets.
The scanner probes addresses on your own LAN to list nearby hosts and their open ports, which macOS gates behind the local-network permission. Nothing is uploaded — results stay on your machine. You can grant or revoke this in System Settings → Privacy & Security → Local Network. This tool is macOS-only.
Yes — any text, URL, or Wi-Fi string. Pick an error-correction level (higher levels survive more damage), then copy the code to the clipboard or share it as an image. Generation happens on-device with no network call.
English, German, Spanish, French, and Turkish. The app follows your system language automatically.
Please email me. Feature requests genuinely shape what gets built next — tell me which tool you keep leaving the app to go use.
