Miletos — Privacy Policy

Last updated: June 14, 2026

What data the app stores

On your device

• Marker records — title, description, GPS coordinates, site type, period, ancient name, source URL, photos, and an optional link to a Pleiades gazetteer entry.
• Photos — stored as binary data attached to markers, never uploaded anywhere except your private iCloud account (see below).
• Discovery categories — your own custom groupings, e.g. "Roman", "Byzantine".
• Place guide cache — Wikipedia article extracts and thumbnails fetched on demand and cached locally for offline use.

In your iCloud private database

If you're signed into iCloud, your markers and categories are automatically synced to Apple's CloudKit private database. This sync:

• Is encrypted in transit and at rest by Apple.
• Is accessible only to you — not to other users, not to the developer.
• Can be disabled by signing out of iCloud or turning off iCloud Drive in Settings.
• Follows Apple's iCloud privacy policy.

Network requests the app makes

Miletos only makes outbound network requests in these situations:

• CloudKit sync — automatic, to Apple's servers, when you're signed into iCloud.
• Place guide refresh — when you tap "Refresh guide," the app fetches the latest Wikipedia summary and thumbnail for that place from en.wikipedia.org. This request includes the article title and your IP address as seen by Wikipedia's servers. See the Wikimedia privacy policy.
• "Read full article" / "View on Pleiades" — opens an in-app browser view; the destination site receives your IP address and standard browser headers.

Miletos never sends your GPS coordinates, photos, marker content, or any personally identifiable information to any server controlled by the developer.

Location

Miletos requests "When In Use" location permission to center the map on your position and to suggest nearby ancient places when you add a marker. Your location is never recorded unless you explicitly create a marker there, and it's never transmitted off your device except as part of a marker synced to your own private iCloud database.

Photos

Miletos requests photo library access to attach images to markers. GPS coordinates embedded in a photo's EXIF data are read entirely on-device. Photos are stored in your private iCloud database and are never sent to any third-party server.

Data the developer never receives

• Your marker content, titles, descriptions, or coordinates
• Your photos
• Your location
• Usage statistics, crash reports, or analytics of any kind

There is no backend server for this app beyond Apple's CloudKit.
