Overview
This policy covers Trek Log, Foursight, 4615, and Nice — four iOS apps developed and published by Jason Irwin.
Trek Log, Foursight, and 4615 collect no data, require no account, and have no server component. They are entirely local-first. There is nothing to sell and no one to sell it to.
Nice is a client for Nice.Social, part of the 10Centuries platform. It communicates with that platform as a necessary function of the app. It does not use advertising, analytics, or third-party tracking of any kind, and it never sells personal data.
What data is collected
Trek Log, Foursight, and 4615: None. These apps collect no personal data, no usage data, no analytics, and no crash reports. Nothing is transmitted to any server.
Nice: Post content, profile information, and account credentials flow between the app and the 10Centuries platform as a direct function of what the app does. The developer operates that platform. This data is never shared with third parties and is not used for advertising or analytics.
Third-party services
Trek Log, Foursight, and 4615: None. No third-party SDKs, analytics, advertising, or crash reporting tools.
Nice: Communicates with the 10Centuries platform, which is developed and operated by the same developer. No third-party analytics, advertising networks, or crash reporting SDKs are used. The App Store itself is Apple's platform and subject to Apple's own privacy policy.
Data stored on your device
Some data is stored locally as a natural part of what each app does.
- Trek Log: Route files are saved as KML to your iCloud Drive. This is your own iCloud account, under your own storage quota. The developer has no access to it.
- Foursight: Photos are saved to your device's Photos library if you choose to save them. The app writes to it with your permission and reads nothing back.
- 4615: Puzzle state is stored locally on your device only. Nothing leaves the device.
- Nice: Your session credentials are stored securely in Apple's Keychain. Post content may be temporarily cached on your device to improve performance. This cache is local only and not transmitted anywhere beyond the 10Centuries platform.
