How Ancient Fish Traps handles your information
Last updated: July 9, 2026
Ancient Fish Traps ("the App") is an offline, self-contained educational application. This Privacy Policy describes what information the App processes and how it is stored.
Summary
The App contains no accounts, no ads and no tracking. We do not collect personal information for analytics, advertising or profiling. All educational content is bundled inside the App and works without an internet connection.
Information Stored on Your Device
The App saves progress locally on your iPhone or iPad using Apple's standard on-device storage (UserDefaults). This data never leaves your device unless you back up your device through Apple iCloud or a local backup.
The following items may be stored locally:
- Whether you have completed the welcome / onboarding flow
- Bookmarked (saved) fish traps
- Which traps you have viewed
- Your best quiz score (overall correct-answer count)
- Your best score per quiz category (Materials, Peoples, Mechanics, History, Geography)
- Total experience points (XP) earned from quizzes
- Number of quizzes completed
- Your longest correct-answer streak
You can reset this progress by deleting the App from your device.
Information We Do Not Collect
The App does not:
- Require you to create an account or sign in
- Collect your name, email address or contact details
- Use analytics or tracking SDKs
- Display advertisements
- Transmit your usage data to our servers (the App has no user-facing server component for content or progress)
- Access your photos, camera, microphone or location for its core educational features
Internet & Third Parties
All trap stories, diagrams, quizzes and timeline content are included in the App bundle. You do not need an internet connection to read content or use quizzes.
The App does not embed third-party content, social media widgets or external analytics services.
Children's Privacy
The App is an educational field guide suitable for curious learners of all ages. Because we do not collect personal information, no child-specific data is gathered by the App.
Apple App Store
If you download the App from the Apple App Store, Apple may collect information according to its own privacy policies and processes (for example, purchase records and device backups). That processing is governed by Apple, not by this App.
App Store identifier: 6788433507
Educational Disclaimer
Historical dates, locations and cultural details in the App are simplified summaries for learning. They are not a substitute for guidance from the communities involved. See the App's Guide & About section for the full warning and disclaimer.
Changes to This Policy
We may update this Privacy Policy if the App's data practices change. The "Last updated" date at the top of this section will reflect any revision.
