Privacy Policy

Last updated: June 1, 2026

Overview

Hash Camera helps users create and verify timestamp evidence for photos. This policy explains what data the app processes and how it is used.

Data We Process

When you create an evidence photo, Hash Camera may process the photo you capture, capture time, server receipt time, device model or device name, membership plan, evidence ID, photo hash, optional blockchain anchor data, and QR code metadata.

When you verify a photo or QR code, Hash Camera processes the QR content or evidence ID required to look up the record.

Photos

Photos used for evidence records are uploaded to our server and stored in Cloudflare R2. The app also saves a QR-marked copy to your photo library when you grant permission. Hash Camera does not delete photos from your photo library.

Local Data

The app stores local history and thumbnails on your device. You can clear this in the Settings tab. Clearing local data does not delete photos already saved to your photo library or evidence records stored on the server.

Apple Sign In and Purchases

If you use Sign in with Apple, the app may store the Apple user identifier and profile information provided by Apple. If paid plans are enabled, purchase status may be used to determine evidence retention.

Purpose

We use data to create evidence records, verify QR codes, compare server-stored photos, apply retention periods, prevent abuse, and maintain the service.

Retention

Evidence retention depends on the active plan at the time of upload. Current app logic uses 5 days for Free, 100 days for Pro, and 365 days for Business. Retention periods may change with published plan terms.

Infrastructure

Hash Camera uses Cloudflare Workers, Cloudflare D1, and Cloudflare R2 for API, database, and file storage.
