Privacy Policy
Last updated: June 24, 2026
Stampo ("we", "us", "our") is a virtual travel passport app that lets you record the places you have visited and collect stamps. This Privacy Policy explains what information the app handles, where it is stored, who it is shared with, and what choices you have.
1. Data stored on your device
Stampo works without an account. The information you create in the app is stored locally on your device and is not uploaded to our servers. This includes:
- Your nickname, and optional profile details (such as gender or birth date) if you choose to enter them
- Countries and cities you mark as visited, including their map coordinates
- Visit dates and notes you write for each stamp (up to 140 characters)
- Stamp styles and customization choices
Because this data lives only on your device, deleting it in the app or uninstalling the app removes it.
2. Data sent to third parties
To operate, the app sends limited information to the following service providers:
- Mapbox — when you view the map or search for a place, your search terms and map requests are sent to Mapbox to return results and map imagery. Mapbox may receive technical data such as your IP address as part of these requests. See Mapbox's privacy policy at mapbox.com/legal/privacy.
- Sentry — if the app crashes or hits an error, diagnostic information (such as the error, device model, and operating system) is sent to Sentry so we can fix problems. This crash data is not tied to a personal account. See Sentry's privacy policy at sentry.io/privacy.
3. How this information is used
- store and display your travel records, stamps, and notes on your device
- deliver the core passport and map experience
- generate your passport and map export images
- diagnose crashes and keep the app stable and secure
We do not sell your data, use it for advertising, or track you across other apps or websites.
4. Your choices
- edit or delete individual stamp records in the app
- uninstall the app to remove all locally stored data from your device
5. Children
Stampo is not intended for children under 13, and we do not knowingly collect personal information from children under 13.
6. Security
We use reasonable measures to protect information handled by the app. No method of storage or transmission is completely secure, and we cannot guarantee absolute security.
7. International processing
Data sent to our service providers (such as Mapbox and Sentry) may be processed in countries other than the one where you live.
8. Changes to this policy
We may update this Privacy Policy from time to time — for example, if we add optional accounts or cloud features in the future. If we make material changes, we will update the "Last updated" date and may provide additional notice where appropriate.
