Privacy Policy
Last updated: 22 October 2026
Nook is a web browser for macOS made by Arun Brahma. It has no user accounts and no analytics, and it runs no servers. This page lists what the app stores on your Mac and the network requests it makes on its own.
What stays on your Mac
- Bookmarks and the optional name you enter on the new-tab page are saved as plain files in your Mac's Application Support folder. They never leave your device.
- History is kept in memory only and is gone when you quit.
- Cookies, cache, and site data created while browsing are cleared automatically when Nook quits.
Network requests Nook makes itself
- Search. Typing a search in the address bar sends it to Google. Google's privacy policy applies to that request.
- Location on the new-tab page. To show your city, the new-tab page asks
get.geojs.iofor an approximate location based on your IP address. Nothing else is sent. The answer is reused for 30 minutes so each new tab doesn't ask again. - Ad blocking. On first launch, Nook downloads its filter lists (EasyList, EasyPrivacy, Peter Lowe's list and uBlock Origin's lists, as packaged by Ghostery's open-source ad blocker) from GitHub and keeps them in a file on your Mac. No browsing data is sent with those requests.
Beyond these, Nook only connects to the websites you choose to visit. Those sites see what any browser would show them.
What we never collect
Nook does not collect your browsing history, bookmarks, or searches. A search you type goes only to Google, as described above. Nook has no telemetry and no crash reporting.
This website
browser.arunbrahma.com uses Cloudflare Web Analytics to count page views. It sets no cookies. The Nook app itself contains no analytics.
The demo video on the home page is hosted on YouTube in its privacy-enhanced mode, and nothing is loaded from YouTube until you press play.
The site also uses PostHog (US cloud) to see where visitors lose interest: which pages they open, how far they scroll, which sections they reach, which links and buttons they click, where on the page clicks land, and how fast pages load. It runs in cookieless mode, so nothing is stored in your browser, and no session recordings are made. To tell visits apart without a cookie, PostHog keeps only a one-way hash of your IP address and browser details mixed with a value that changes every day; the IP address itself is discarded. We do not build profiles of visitors.
If you use the contact form, your name, email address and message are emailed to me through Resend, our email provider, so I can reply. This site does not store them. Cloudflare Turnstile, loaded only on the contact page, checks that a person and not a bot is sending the form; Cloudflare handles that check under its own privacy policy.
When you download Nook from this site, the download is counted with the date, your country, region, and city as Cloudflare estimates them from your IP address, your browser and operating system, and the site you came from. Your IP address itself is not stored.
Children
Nook is a general-purpose browser and is not directed at children under 13. It does not knowingly collect information from anyone.
Changes
If this policy changes, the new version will be posted here with an updated date.
