Privacy Policy
Last updated: 26 August 2026
The short version. browserNexus has no servers. The macOS app makes no network connections at all. The browser extensions talk to one thing — the browserNexus app running on the same Mac — over a local channel that never touches the internet. There is no account, no telemetry, and nothing about your browsing is uploaded anywhere.
What the browser extension reads
To show your windows and tabs and apply the right zoom to them, the extension reads:
- Tab titles and URLs, and which window each tab belongs to.
- Which tab and window are active, so the app can show and change the right one.
- Zoom levels the browser is currently applying.
This is sent to the browserNexus app on the same computer, using your browser's native messaging channel — a direct pipe between the browser and a program on your machine. It does not go over a network, and no other program receives it.
Tab previews (optional, off by default)
If you turn on tab previews, the extension takes a picture of the visible tab so the app can show a thumbnail. This requires your browser's page-access permission, which the extension does not request at install — you are asked only if you enable previews, and you can revoke it at any time in your browser's extension settings. Thumbnails are downscaled, held in the app's local cache, and never sent anywhere. If you never enable previews, no page content is read at all.
What the macOS app stores
Everything below is written only to your own Mac, under
~/Library/Application Support/com.browsernexus.app/, and is deleted when you remove
that folder.
| What | Why |
|---|---|
| Zoom rules, exceptions, display labels, preferences | So your settings survive a restart. |
| Window names you have assigned | So a window keeps its name. |
| Recent session history — windows and tabs you had open | So you can look back at a previous session. Limited to the last few sessions. |
| Display connection history | So the app can recognise a monitor it has seen before and apply the right zoom. |
| Diagnostic logs | So a problem can be investigated. They stay on your Mac unless you choose to send them. |
Location
The app can annotate display-connection history with a city name — so the history can tell you that a monitor was last connected in, say, Seoul rather than only giving a timestamp. This uses macOS Location Services, and macOS asks your permission first. If you refuse, the feature is simply skipped and everything else works normally.
Only the city is stored. No street address and no coordinates are written to disk. Resolving a city from a position is performed by macOS itself, which may contact Apple to do it; that request is governed by Apple's privacy policy, not ours. browserNexus never receives or transmits your position.
What we collect: nothing
We do not operate a server that receives your data. We do not have accounts, and we cannot see your tabs, your browsing, your settings, or your machine. There is no analytics or crash reporting inside the app or the extensions.
We do not sell or transfer user data to third parties. We do not use it for anything unrelated to running browserNexus. We do not use it to assess creditworthiness or for lending.
This website
browsernexus.com uses Google Analytics to count visits and see which pages are read. That measures the website only — it has no connection to the app or the extensions, and it cannot see anything inside them. Google Analytics sets cookies and processes data under Google's privacy policy. Browser "Do Not Track" settings and content blockers will stop it.
Removing your data
Uninstalling removes it. To delete everything the app has stored, remove the folder
~/Library/Application Support/com.browsernexus.app/. Removing an extension from your
browser removes what it kept there. Nothing is retained elsewhere, because there is nowhere else.
Children
browserNexus is a utility for managing browser windows and is not directed at children under 13.
Changes
If this policy changes, the date at the top changes with it, and material changes will be noted in the app's release notes.
