Privacy Policy
Effective November 7, 2026
DisplayPeek is a developer tool. It does not collect any personal data. It has no analytics, tracking, advertising or accounts, and the developer receives nothing from the app.
Data stored on your Mac
Everything DisplayPeek keeps stays on your Mac:
- Design dashboards: the HTML files you preview, in the app's folder or a folder you choose.
- Settings: your device, palette, theme and other preferences.
- Device API keys: stored in the macOS Keychain.
- Screen history: recent images from your devices, saved as PNG files in the app's container. You choose how many to keep in Settings.
Network connections
DisplayPeek connects directly from your Mac to these services. None of these requests go through the developer.
- trmnl.com: to load the display framework stylesheets and scripts used to render previews.
- trmnl.com device API: only if you add a device. The app sends your device API key to request the screen that device is currently showing, or the next screen when you ask for it.
- Screen images: the app downloads the image address returned by the device API.
- Your own HTML: a design dashboard can reference images, fonts or scripts on other websites. The preview loads them the way a web browser would.
These services handle requests under their own privacy policies.
Live Screens on this website
The Live Screens page stores the device names and API keys you add in your browser's local storage. Your browser sends each key only to trmnl.com, to get the screen that device is currently showing, and then loads the screen image from the address trmnl.com returns. This website never receives your keys. To delete them, use Forget all devices on that page or clear this site's data in your browser.
This website uses no cookies, analytics or tracking. It is hosted on Cloudflare, which processes standard request data such as IP addresses to deliver the pages.
Deleting your data
Remove a device in the app to delete its API key and screen history. Deleting DisplayPeek and its data removes its settings and screen history. Your design dashboard files are yours to keep or delete.
Changes
If this policy changes, the new version will be posted on this page with a new effective date.
