Privacy Policy — WiFi Check

Last updated: 10 May 2026 · Publisher: Nordic Node, Netherlands

This is the privacy policy for the WiFi Check Android application (nl.nordicnode.wificheck), hosted at https://nordicnode.nl/wificheck/privacypolicy.html.

1. What WiFi Check does

WiFi Check tells you which WiFi standards your Android device supports (WiFi 4 through WiFi 7), based exclusively on:

Android's own WifiManager.isWifiStandardSupported() API,
live WiFi connection events on your device, and
Android's WifiManager.is6GHzBandSupported() API.

The app makes no network calls of its own to determine these answers. There is no remote database, no model lookup, no analytics, no telemetry.

2. Data we collect on-device

WiFi Check stores a small set of data locally on your device, in Android's DataStore preferences file. Specifically:

For each WiFi standard (WiFi 4, 5, 6, 6E, 7), the timestamp at which that standard was first observed via a live WiFi connection on this device.

That is the entire on-device dataset. We do not store, log, transmit, or otherwise process:

WiFi network names (SSIDs);
BSSIDs / MAC addresses;
your location, GPS data, or location-derived information;
personal information (name, email, phone number);
device identifiers other than what AdMob handles for advertising (see §4).

You can delete the on-device dataset by clearing the app's storage in Android Settings or by uninstalling the app.

3. Permissions

WiFi Check requests the following Android permissions:

ACCESS_WIFI_STATE, ACCESS_NETWORK_STATE — needed to read your current WiFi connection's link speed, frequency, signal strength, and standard. These are normal-level permissions and do not prompt at runtime.
NEARBY_WIFI_DEVICES (Android 13 and above) — only requested when you explicitly tap "Show network name". Declared with the neverForLocation flag — we do not derive your location from WiFi.
ACCESS_FINE_LOCATION (Android 11 and 12 only) — same use as above: only when you tap "Show network name". Capped to API 32 in the manifest.

If you decline these permissions, the rest of the app works fine; only the network name display is disabled.

4. Advertising and AdMob

WiFi Check is supported by ads served by Google AdMob. To comply with EU rules, on first launch in EU/EEA regions you will see a Google-provided consent form asking what data, if any, AdMob may use for ad personalisation. You can change this choice any time via the app's "Privacy options" menu item.

When you grant consent, AdMob may collect or use your Advertising ID and limited device data for ad delivery and frequency capping. AdMob's privacy practices are described at https://policies.google.com/technologies/ads.

When you decline, AdMob serves contextual (non-personalised) ads.

We do not use any analytics SDKs (no Firebase Analytics, no Crashlytics, no third-party trackers).

5. Data sharing

We do not share data with third parties beyond Google AdMob as described above. We do not sell data, ever.

6. Children

WiFi Check is rated for everyone but is not specifically directed at children under 13. We do not knowingly collect personal information from children.

7. Changes to this policy

If we change this policy, we will update the "Last updated" date at the top. Material changes that affect what data is processed will be communicated via an in-app notice on the next launch after the change.
