Blackwell Data Sheets Privacy Policy

Effective date: September 9, 2026

Blackwell Data provides Blackwell Data Sheets, an Android app for importing photographs of tables, viewing and editing sheet data, and exporting CSV files. Contact us at contact@blackwelldata.com. Developer website: blackwelldata.com.

Your photos and sheets

You choose an image using Android's system photo picker. The app processes that image on your device to detect table borders and recognize text. Blackwell Data does not receive your selected photos, recognized text, or saved sheets through an app-operated server.

Sheets you save are stored in the app's private storage on your device. Confirmed edits update that local copy. You can delete saved sheets from the Saved sheets screen. Clearing the app's storage or uninstalling the app removes its local sheets. This app does not request Android cloud backup for its private app data. Keep separate CSV exports if you need another copy.

Exports

You select the destination for exported files through Android's file picker. A selected destination may be a local folder or a third-party document or cloud-storage provider. That provider handles exported files under its own terms and privacy policy. Deleting a sheet from the app does not delete files you exported elsewhere.

Text recognition and technical diagnostics

The app includes Google's ML Kit text recognition software. Recognition of the selected image runs on the device. Google's ML Kit SDK may collect technical information for diagnostics and usage analysis, including device and application information, installation identifiers, performance measurements, recognition configuration and input/output sizes, feature events, and error codes. This technical collection is separate from the contents of your photos and tables.

For Google's description of this SDK data handling, see ML Kit data disclosures and Google's Privacy Policy.

Accounts, advertising, and purchases

The app does not require an account and includes no advertising or in-app purchases. Blackwell Data does not sell your photos or sheet contents.

Support messages

If you email us, we receive the email address and information you choose to send. We use it to respond and investigate the issue. Avoid sending documents containing information you do not want to share. You may contact us to request deletion of your support correspondence, subject to any retention required by law.

Changes and questions

We may update this policy when the app's behavior changes. The effective date above identifies the current version. For privacy questions or requests, contact contact@blackwelldata.com.
