StampWise Privacy Policy

Effective September 15, 2026

StampWise analyzes a photo only when you ask it to identify a stamp. The app resizes and compresses the image on your device, then sends it over HTTPS through our Cloudflare Worker to our AI service provider, OpenAI, for identification.

Data we handle

• The selected stamp image and generated identification response are processed to provide the requested result.
• A random app-installation identifier and network address are processed for rate limiting and abuse protection. The identifier is not an advertising identifier and is not used for tracking.
• Operational logs contain a generated request identifier, result or error category, upstream status/code from a restricted allowlist, and request duration. They do not contain the photo, stamp content, purchase receipt, or AI credential.
• Saved Collection and History records, including their images, stay in the app's local storage on your device.
• Subscription purchases and payment information are processed by Apple. We do not receive your payment card details.

Providers and purposes

Cloudflare provides network and Worker infrastructure. OpenAI analyzes the selected image and returns structured identification information. OpenAI API data is not used to train models unless the account owner opts in. Requests set provider application storage to disabled; OpenAI may retain API inputs and outputs in abuse-monitoring logs for up to 30 days under its default data controls, subject to its terms and legal exceptions.

Retention

We do not maintain our own server database of uploaded photos or identification results. Request rate-limit counters are short-lived. Operational logs follow the retention configured for the Cloudflare account. Local Collection and History records remain until you delete them in Settings or remove the app. Provider processing and retention follow the provider terms described above.

Your choices and deletion

You can cancel before sending an analysis, choose not to save a result, delete Collection and History records from Settings, and remove the app to remove its local data. Apple manages subscription history, cancellation, and subscription controls.

Tracking, sale, and children

We do not track you across other companies' apps or websites, and we do not sell personal information. The app is not directed to children under 13.

Changes and contact

We may update this policy when the product, providers, or legal requirements change. For privacy questions or deletion help, visit StampWise Support.
