Wireless Charging Check — Privacy Policy
Effective date: 31 May 2026
This privacy policy explains exactly what data Wireless Charging Check (“the app”, “we”, “our”) collects, stores, and shares. Wireless Charging Check is published by Nordic Node, based in the Netherlands.
- The app does not collect, transmit, or sync any personal data.
- The app stores two local timestamps describing when wireless and dock charging were first observed. These never leave the device.
- The app shows AdMob banner ads, which may use your Advertising ID and IP-derived location data under your consent.
- We use the Google UMP SDK to request your advertising-consent choice in the EU/EEA and persist it locally.
What the app reads from your device
When the app is open, it reads from the Android BatteryManager surface:
- Whether a wireless charger is connected (
BATTERY_PLUGGED_WIRELESS) - Whether a dock charger is connected (
BATTERY_PLUGGED_DOCK, Android 13+) - Battery voltage, current, temperature, level, status, scale, and energy/charge counters
These readings are displayed live on the screen. They are never stored on the device beyond the current session, and they are never transmitted off the device.
What the app stores locally
Two Long values, in an Android DataStore preferences file:
wireless_input_first_seen_epoch_ms— Unix timestamp (milliseconds) of the first time the app observed a wireless charging event.dock_input_first_seen_epoch_ms— Unix timestamp of the first time the app observed dock charging.
That is everything. There is no other persistent storage by the app itself. The DataStore
file is excluded from Android Auto Backup and Device Transfer (see
data_extraction_rules.xml and backup_rules.xml in the app’s source code).
Permissions
The app declares only one permission:
com.google.android.gms.permission.AD_ID, which the AdMob SDK requires to read the
device Advertising ID for personalised or non-personalised advertising depending on your
consent choice.
The app declares no runtime permissions.
Advertising
The app displays AdMob banner ads at the bottom of the screen.
Through AdMob, Google may collect:
- Advertising ID (if you consent)
- IP-derived approximate location
- App interactions (taps on the ad, viewability metrics)
- Crash logs (via Google Play Services)
Google’s privacy policy for advertising: https://policies.google.com/technologies/ads
To withdraw or change your consent at any time, open the app, tap the overflow menu (︙ top-right), then Privacy options.
In jurisdictions where consent is required (EU/EEA, UK, Switzerland), the Google UMP SDK presents a consent form on first launch. Your choice is persisted locally by the UMP SDK.
What we do NOT do
- We do not run any analytics SDK in the app (no Firebase Analytics, no Mixpanel, no internal telemetry of any kind).
- We do not transmit your battery readings off the device.
- We do not store charging history.
- We do not access your location, contacts, files, microphone, camera, or any other sensors.
- We do not maintain a “supported devices” list and we do not transmit your phone’s model or hardware identifiers anywhere.
- We do not show interstitial ads, video ads, or rewarded ads — banner only.
Children’s privacy
The app is rated for Everyone and is suitable for use by children. Because the app does not
collect personal data, it does not knowingly collect any information from children either.
Advertising is handled per the AdMob policy linked above; we have set
setTagForUnderAgeOfConsent(false) in line with AdMob’s documentation.
Changes to this policy
If we change this policy, we will update the effective date at the top of this page. Material changes will be highlighted in the app’s About dialog.
