FieldScale does not collect, transmit, or store any personal information on external servers. All PDF files, measurements, calibration data, and settings are stored locally on your device only.
Photo Mode requires camera access to photograph drawings. Photos are processed entirely on-device and are never uploaded or shared with any third party.
The Auto Cal AI feature sends a small cropped image of a scale notation to Anthropic's API for scale detection, routed through a secure Cloudflare proxy. No personal information is included in this request. The image is transmitted over HTTPS and is not retained by Anthropic or the proxy beyond processing the individual request. This feature is optional and only triggered by an explicit user action.
FieldScale offers an optional Google Drive integration that allows you to import plan files directly from your Google Drive. FieldScale requests the drive.file scope, which limits access exclusively to files you explicitly select — FieldScale cannot access, view, or browse any other files in your Drive. Selected files are downloaded to your device only and are not uploaded to FieldScale servers or shared with any third party. You can revoke FieldScale's access to your Google Drive at any time via your Google Account settings at myaccount.google.com/permissions.
FieldScale uses Firebase Crashlytics solely to collect anonymous crash reports. This helps us identify and fix bugs. Crash reports may include device model, OS version, and a stack trace of the error. No personally identifiable information is included. FieldScale does not use any advertising, tracking, or general analytics services.
FieldScale uses the following third-party services: Anthropic Claude API for the optional Auto Cal AI feature; Google Firebase Crashlytics for anonymous crash reporting; Google Drive API for the optional Drive file import feature (only when explicitly authorized by the user); and Cloudflare as a secure proxy for AI API requests. No advertising networks, data brokers, or other third-party SDKs are used.
All plan data remains on your device. The only external transmissions are: optional AI feature requests routed through a secure proxy, anonymous crash reports, and file downloads from Google Drive when you explicitly use that feature. No personal information is included in any of these transmissions.
FieldScale is intended for professional use and is not directed at children under 13. We do not knowingly collect any information from children.
We may update this Privacy Policy from time to time. Updates will be reflected with a revised date. Continued use of the app after changes constitutes acceptance of the updated policy.
