What we collect.
Nook has no accounts and never sees your clipboard, screenshots, notes or files. Here is everything the app and this website send, and how to stop it.
The Nook app
Once a day while Nook is open, it sends one anonymous usage count to our server on Cloudflare. That count holds:
- a random install id made on your PC, which isn’t tied to you or your account,
- the Nook version and the Windows build number,
- how many times the panel opened and how many minutes it stayed open since the last count,
- how many times each built-in tool was used, like “Timer: 3”. Plugin names are never sent.
The server never reads or stores your IP address, and tool counts are added up per day with no install id attached. Usage stats are on by default. Turn them off in Settings > Advanced > Anonymous usage stats, which also deletes any counts still waiting to be sent.
Nook also asks GitHub for new versions every few hours, downloads plugins from GitHub when you install them, and opens Google Lens in your browser when you use Lens search. Plugins are separate programs and make their own network calls.
This website
We count page views and clicks on buttons such as Download with Umami. Umami sets no cookies and doesn’t follow you across other sites.
If you allow it in the banner, we also record anonymous heatmaps and session replays with Microsoft Clarity, to see where pages are confusing. Clarity sets cookies and hides text you type into forms. It never loads unless you click Allow.
Questions
Nook is open source, so you can read exactly what it sends in stats.rs and the server code. For anything else, open an issue on GitHub. Back to Nook.
