GasTrunk runs entirely on your device. It has no account and no server. We do not collect, transmit, sell, rent, or share your personal information.
Anything you enter (inputs, saved jobs, history, presets, and any photos you choose to attach) is kept in the app's private storage on your phone or tablet. It stays on your device. You can delete it inside the app or by uninstalling the app.
Saved jobs, inputs, presets, history, and attachments remain on your device until you delete them in GasTrunk, clear the app's Android storage, or uninstall the app. Anvilfield has no server-side account or job copy to delete. Files you export remain with the destination you selected until you delete them there.
Working data uses Android app-private storage and your device's security controls. GasTrunk does not transmit job records to Anvilfield. Protect access to your device and review the privacy and security terms of any app or service you choose for an exported file.
If a feature needs a device permission (for example, the camera or your photos to attach a picture to a report), it is requested only when you use that feature, and the data stays on your device. The app does not access your location, contacts, or accounts unless a feature you use clearly asks for it.
GasTrunk contains no third-party analytics, no advertising, and no tracking SDKs. Purchases are handled by Google Play Billing under Google's own terms.
GasTrunk is a professional tool intended for adults and is not directed to children.
If a future version of GasTrunk adds a feature that uses the network or collects data (for example, optional cloud backup), we will update this policy and the app's Google Play Data Safety details before that feature ships.
