Privacy Policy
Last updated: 13 October 2026
Summary: NetInfo has no servers and does not collect any personal data. Your browsing activity never leaves your device. To show your public IP address and ISP, NetInfo makes lookup requests to the third-party services listed below.
What NetInfo does
NetInfo is a Safari browser extension for macOS that displays technical networking information about the website currently open in your browser tab, including IP address, TLS version, certificate details, HTTP protocol, and connection timing metrics.
NetInfo also includes an optional menu bar item, desktop widgets, and a Control Center control that show your Mac's hostname, its local and public IP addresses, your ISP, and the response time to endpoints you choose.
Data we collect
NetInfo collects no personal data. Specifically:
- We do not collect your browsing history
- We do not store any information about the websites you visit
- We do not collect or store your IP address (see Third-party services for the lookups that reveal it)
- We do not use cookies or any tracking technologies
- We do not create user accounts or profiles
- We do not transmit any data to our servers (we have none)
Third-party services
NetInfo uses the ipapi.co (opens in a new window) API to look up ASN and ISP information for a website's IP address. When you open the NetInfo popup on a website, the IP address of that website's server is sent to ipapi.co to retrieve provider information.
Please refer to ipapi.co's Privacy Policy (opens in a new window) for details on how they handle API requests.
The menu bar item, widgets, and Control Center control find your public IP address by requesting it from ipify (opens in a new window) (api.ipify.org and api6.ipify.org). As with any internet request, ipify sees your public IP address when it answers. NetInfo then sends your public IP address to ipapi.co to look up your ISP — only when the address changes, not on every check.
Response-time tests connect to the endpoints you configure in NetInfo's settings (by default, Cloudflare's 1.1.1.1). A TCP test opens and immediately closes a connection without sending any data; an HTTP test sends a single HEAD request.
NetInfo does not use any analytics, advertising, or crash reporting services.
On-device processing
All connection metrics — including TLS version, certificate expiry, HSTS status, HTTP protocol, and timing data — are gathered entirely on your device using Apple's built-in networking APIs. This data is displayed in the popup and is not sent anywhere.
To power the widgets, NetInfo keeps a small amount of data on your Mac only: a summary of the last website you inspected (its hostname, server IP address, protocol, TLS version, and timings), your current network details, and a short history of response-time results. This data stays in NetInfo's own storage on your device and is replaced as new results arrive. It is never sent to us — we have no servers.
Children's privacy
NetInfo does not knowingly collect data from anyone, including children under the age of 13.
Changes to this policy
If this privacy policy changes, the updated version will be posted at this URL with a revised date. NetInfo will never introduce data collection without updating this policy first.
