Privacy Policy

Effective date: April 2026

Overview

Stamp Hunt is a personal travel stamp collection app. It is designed with a simple principle: your data stays on your device. We do not collect, transmit, or share any personal information. The app has no server component, no user accounts, and no network communication of any kind.

Data Stored on Your Device

Stamp Hunt stores the following information locally on your device only:

• Your display name (optional, entered by you)
• Your home country preference (selected by you)
• A profile photo (optionally imported from your photo library)
• Your stamp collection - country codes, dates, airport codes, and stamp tiers only (no personal identifiers)

All data is stored in your device's local storage. Nothing is synced to the cloud or accessible to us or any third party.

Camera Usage

Stamp Hunt requests camera access for the following features:

• Reading barcodes on boarding passes
• Scanning passport pages to detect entry/exit stamps via OCR

Camera frames are processed in real time and immediately discarded. No images or video are stored or transmitted at any point.

Boarding Pass Scanning

When you scan a boarding pass barcode, the app extracts flight details (origin, destination, flight number, seat, and booking reference) to determine which country you are traveling to.

This information is used only during the scanning session to identify the destination country. None of the boarding pass details - passenger name, booking reference, flight number, or seat - are stored on your device. They are discarded as soon as you leave the scanning screen.

Location Services

Stamp Hunt may request your location to verify which country you are currently in. This is used to upgrade stamps to a higher tier when your GPS position matches the stamp country.

Your exact GPS coordinates are never stored. The app uses country code only from your position for verification, and then discards it. Location access is optional - you can always add stamps manually without enabling location services.

No Network Communication

Stamp Hunt operates entirely offline. Specifically:

• No analytics or telemetry of any kind
• No advertising or ad tracking
• No third-party SDKs that collect data
• No cloud sync, iCloud storage, or remote backups
• No data sent to us or any server

Children's Privacy

Stamp Hunt does not collect any personal information from anyone, including children. Since no data leaves your device and no accounts are created, the app is inherently compliant with COPPA, GDPR, and similar regulations regarding children's data.

Data Deletion

You can delete all of your data at any time from the Profile tab using the Delete All Data option. This permanently removes your name, home country, profile photo, and entire stamp collection from the device. You can also simply delete the app, which removes all associated data.

Changes to This Policy

If we update this privacy policy, the revised version will be included in a future app update. Since the app has no network access, we cannot notify you outside of an app update. The effective date at the top of this policy will always reflect the most recent revision.
