Gnip — Privacy Policy
Effective August 31, 2026 · Last updated August 31, 2026
Gnip does not collect, store, or transmit any personal information about you. There are no accounts, no analytics, no advertising, no tracking, and no third-party SDKs that report on your use of the app. Nothing you do in Gnip is sent to Greninger Enterprises, LLC, and we have no servers that receive your data.
Gnip is a network diagnostic tool. It works by making network requests — that is its entire purpose — so this policy explains exactly which requests it makes, what each one carries, and who receives it. This policy covers the Gnip apps for iOS, iPadOS, Android, and macOS.
Information that stays on your device
Gnip stores a small amount of data locally, in the app's own private storage. This data is never transmitted anywhere. It is deleted when you uninstall the app.
- Command history — the commands you type during a session.
- Network scan baseline — when you run
lanscan, Gnip saves a snapshot of the devices it found on your local network (IP addresses, hardware/MAC addresses, device names, and open ports) so that a laterlanscan --diffcan tell you what changed. This snapshot describes your own network and remains on your own device. - Display preferences — such as the units used for weather.
Information that leaves your device
Gnip contacts outside services only when you run a command that requires it. Each request is caused by an explicit action you take. Gnip never makes network requests in the background.
| When you run | Gnip contacts | Which receives |
|---|---|---|
ping, traceroute, mtr, tcping | The host or IP address you specify | A standard network probe from your device, exactly as any network utility would send. The destination sees your IP address, as it would for any connection you make to it. |
dig, nslookup, host | Cloudflare, Google, or Quad9 public DNS-over-HTTPS resolvers | The domain name you asked to look up, and your IP address. |
speedtest | Cloudflare (speed.cloudflare.com) | Test traffic used to measure throughput, and your IP address. |
myip | Cloudflare | A request whose response reports your public IP address back to you. |
weather | U.S. National Weather Service (api.weather.gov) and Open-Meteo (api.open-meteo.com) | Your approximate coordinates, and your IP address. See below. |
lanscan, arp, ifconfig | Nothing outside your local network | These commands communicate only with devices on the network you are already connected to. Their results are not transmitted off your device. |
These services are independent third parties. Gnip has no business relationship with them and does not send them any identifier for you or your device. Their handling of the requests they receive is governed by their own privacy policies: Cloudflare, Google, Quad9, National Weather Service, Open-Meteo.
Location
Gnip requests location access for one feature: the weather command, which needs to know roughly where you are in order to report the forecast and any active weather alerts for your area.
- Approximate location only. Gnip explicitly requests reduced-accuracy location. It does not ask for and cannot obtain your precise position.
- Only while you are using the app. Gnip has no background location access. Your location is read only in the moments after you run
weather. - Never stored. Your coordinates are used to build the weather request and are then discarded. Gnip does not keep a location history.
- Sent only to the weather providers. Your approximate coordinates are included in the requests to the National Weather Service and Open-Meteo so they can return the correct forecast. They are sent nowhere else.
- Optional. You can use
weatherwithout granting location access at all by supplying coordinates yourself:weather --coords 32.78,-96.80. If you deny the permission, only the automatic-location behavior is lost; the rest of the app is unaffected.
You can revoke location access at any time in your device's system settings.
Local network access
On iOS, macOS, and Android, Gnip asks for permission to interact with devices on your local network. This supports lanscan, which discovers what is connected to the network you are on, and the related arp and ping functionality. Gnip restricts scanning to networks your device is actually attached to. Everything discovered stays on your device.
What Gnip does not do
- No user accounts, sign-in, or registration.
- No analytics, usage measurement, crash reporting, or attribution SDKs.
- No advertising and no advertising identifiers.
- No tracking, and no sharing or sale of data with data brokers or any other party.
- No access to contacts, photos, calendar, microphone, camera, health data, or files.
- No collection of your command history, scan results, or test results by us or anyone else.
Children
Gnip is a general-purpose utility and is not directed to children. It does not knowingly collect information from anyone, including children under 13.
Your rights
Because Gnip holds no personal data about you, there is nothing for us to disclose, correct, export, or delete on request. All data the app creates lives on your device and is removed entirely when you uninstall the app. This is true regardless of where you live, including under the GDPR, the UK GDPR, and the CCPA/CPRA.
Changes to this policy
If this policy changes, the updated version will be posted at this address with a revised effective date. Material changes to how the app handles data will also be noted in the app's release notes.
