Overview
These apps do not collect your data. They do not phone home. They do not have accounts, servers, or advertising networks. There is nothing to sell and no one to sell it to.
This policy covers Trek Log, Foursight, and 4615 — three iOS apps developed and published by Jason Irwin.
What data is collected
None. These apps collect no personal data, no usage data, no analytics, and no crash reports through any developer-controlled system. Nothing is transmitted to any server operated by or on behalf of the developer.
Third-party services
None of these apps use third-party SDKs, analytics services, advertising networks, or crash reporting tools. The App Store itself is Apple's platform and subject to Apple's own privacy policy — that is entirely outside the developer's control or involvement.
Data stored on your device
Some data is stored locally as a natural part of what the apps do. All of it stays on your device or in your own iCloud account.
- 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. This is standard iOS photo storage — 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.
