Report an issue
Use this form to send feedback or describe a problem. Include your macOS version and what you were doing in the app when possible.
All fields marked * are required.
Common topics
- File access: macOS may prompt for permission to read files or folders you select. Grant access only for locations you intend to hash.
- VirusTotal: Optional lookups send a cryptographic hash of a file to VirusTotal’s service, not the full file. A VirusTotal API key is optional; without your own key, public API limits may apply.
- Keys and settings: Optional keys can be stored in your Mac’s Keychain. Reset or reinstall options in the app follow standard macOS behavior for app data.
Privacy
How data is handled in the app is described in the privacy policy.
