Last updated November 5, 2026. This policy covers all apps published by AppMast: MacSense, MacSense Pro, Sky Wallpaper, AutoFolio, SysScope, Dwelling Docs, BingeQueue, Spectral Siphon, and Simplitext.
What we collect
Our apps are designed to keep your data on your own device and, where an app offers sync, in your own iCloud account — not on our servers. We do not operate a central database of user content. Some apps may send anonymous crash and performance diagnostics to help us fix bugs; you can control this from your device's Privacy settings at any time.
Third-party services
Where an app uses a third-party service to provide a feature — for example, AI-assisted recommendations in BingeQueue, or streaming-service metadata — that request is made directly from your device to that provider, and their own privacy policy governs what they do with it. We don't sell or share your data with advertisers.
MacSense and MacSense Pro
MacSense has no account, analytics, tracking or ads, and sends no crash reports. Your files, the list of apps on your Mac, and its readings stay on your Mac. Settings › Privacy in the app lists every time it reached the internet, when, to which server, and exactly what it carried. It does so only in these cases:
- Getting your Pro unlock code (App Store edition): the app sends Apple’s signed proof that this copy was bought. It contains no name or email.
- Activating MacSense Pro, and confirming the activation each time it opens: your unlock code, the Mac’s hardware ID, its name and model, and the macOS and MacSense versions. We keep these to enforce the five-Mac limit and to show you, on the Manage your license page, which Macs use your code. Freeing a Mac there removes it. Email us to have all records for your code deleted.
- Checking for updates (MacSense Pro, once a day, can be turned off in Settings): a request for the update list at appmast.com, which names the MacSense version.
- Looking up an app (only when you press “Look up what it does”): the app’s ID or name is sent to Apple’s App Store search (itunes.apple.com) to get its description. Nothing about you or your Mac is sent.
- Network tools you start: the website check, port check, ping, route trace and name lookups contact the address you type; the speed test uses macOS’s own test against Apple’s servers in MacSense Pro, or downloads test data from Cloudflare in the App Store edition; Public IP asks Cloudflare, which sees your internet address as any website does.
Our web server keeps standard access logs (internet address, time and page requested) for security, as most websites do.
Sky Wallpaper
Sky Wallpaper has no account, analytics, tracking or ads. AppMast runs no server for it and receives no data from it. It changes your wallpaper only after you choose “Start Changing My Wallpaper”, and makes no location or weather request before then. It reaches the internet only in these cases:
- Getting your weather: the app asks Apple Weather (WeatherKit) for conditions at your location, or at the city you choose. Apple’s own privacy policy governs that request.
- Checking for an aurora: at latitudes of 40° or more, the app fetches NOAA’s public planetary Kp index at most every three hours. The request carries no location and no identifier.
Your last location, chosen city and settings are stored on your Mac only. Sky Journal pictures and their short summaries are stored on your Mac only and are never uploaded. Sky moments are local notifications, and permission is requested only when you turn them on. The app writes a file only where you choose, through the Save panel.
Simplitext
Simplitext has no account, analytics, tracking or ads. AppMast runs no server for it and receives no data from it. Your documents stay on your Mac and are written only where you save them.
- Markdown preview is drawn on your Mac, and the app blocks every web address in a document, so a preview cannot load anything from the internet.
- The AI Writing Assistant uses Apple’s on-device language model, on Macs that support Apple Intelligence. Your text is not sent to AppMast or to any third party by the app.
- Folders you open are remembered by macOS as a permission on your Mac, so [[links]], the sidebar and Find in Folder keep working.
- Your settings, recent files, snippets and crash-recovery copies are stored on your Mac only.
Your choices
You can review or reset what an app has access to (camera, photos, network, notifications) from your device's Settings app at any time. Deleting an app removes its local data from your device; iCloud-synced data can be removed from iCloud in Settings as well.
Children's privacy
Our apps are not directed at children under 13, and we do not knowingly collect personal information from children.
Security and disclaimer
We take reasonable steps to protect data handled by our apps, but no method of storage or transmission is completely secure. This policy describes our practices; it doesn't create any warranty, and our liability is limited as described in our Terms of Service.
Changes to this policy
If this policy changes, we'll update the date at the top of this page.
