Who we are
Wi-Fi Validator is a free Android app published by Diothas Systems, LLC. It measures the Wi-Fi signal strength in each room of your home and suggests ways to improve weak coverage.
Questions about this policy or your privacy: privacy@wifivalidator.com.
What the app collects
Nothing is sent to us. The app has no user accounts, no login, and no backend server that stores your information. Here is every category of data the app touches and where it goes:
| Data | Where it goes | Kept? |
|---|---|---|
| Wi-Fi signal readings, room and floor names, estimated home size | Stored in local app storage on your device | Until you erase them or uninstall the app |
| Your email address (only if you email yourself a report) | Passed straight to your own email app to fill in the “To” field | Not stored. Never transmitted to us |
| Approximate/precise location | Used momentarily by Android to permit a Wi-Fi reading. Not written down, not sent | Not kept |
| Advertising ID and standard ad request data | Google AdMob (see “Advertising” below) | Per Google’s retention policy |
We do not collect your name, contacts, photos, files, browsing history, or the name or password of your Wi-Fi network. We have no analytics SDK and no crash-reporting SDK.
Why the app asks for location permission
Android requires apps to hold the location permission before the operating system will report Wi-Fi signal information — this is a Google platform rule, not a choice we made. The app uses the permission only at the moment you take a reading, purely so Android will return the signal strength.
We do not record, store, or transmit your location. You can deny the permission; coverage tests will not be able to run without it, but the rest of the app still works.
Emailing your results
When you choose to email a report, the app builds the text on your device and hands it to your own email application with the address you typed already in the “To” field. You press send — your mail provider delivers it.
The address is held in the app's memory only long enough to open that email, is never written to storage, and is never sent to us or anyone else. We have no mailing list and will never email you.
Advertising Google AdMob
The app displays banner ads supplied by Google AdMob so it can stay free. To select ads, Google collects a device advertising identifier along with standard ad-request information such as approximate location derived from IP address, device type, and app version. This data goes to Google, not to us — we only receive anonymous, aggregate earnings totals.
How Google uses data from apps that use its services is described in Google’s Privacy & Terms.
You can reset or delete your advertising ID at any time in Android Settings → Privacy → Ads, which also lets you opt out of ad personalisation device-wide.
Consent in the EU, UK and Switzerland
If you use the app in the European Economic Area, the United Kingdom, or Switzerland, you will be shown a consent form the first time the app runs, presented through Google’s certified User Messaging Platform. You choose whether to allow personalised ads.
- If you consent, ads may be personalised using the advertising identifier.
- If you decline, the app requests non-personalised ads only. It remains fully usable.
- You can change your choice at any time in the app under About → Ad privacy choices.
Our legal basis for serving personalised advertising is your consent. Because we hold no personal data ourselves, requests to access or delete your data are handled by erasing local data in the app (About → Erase my saved tests) or uninstalling it; for anything held by Google, use the Google links above.
Amazon affiliate links
Where the app recommends equipment, the links go to Amazon. Diothas Systems, LLC participates in the Amazon Associates Program and may earn from qualifying purchases at no extra cost to you. Following such a link takes you to Amazon, where Amazon’s own privacy policy applies. We are not told what you buy — only aggregate commission totals.
The website
This policy covers the app. On wifivalidator.com itself we set no cookies, run no analytics service, and load no third-party trackers.
The one exception is our gear page: when someone taps a product link there, the page adds 1 to a counter for that product so we can see which of the three is most popular. That counter is a plain tally — three numbers and a date. No IP address, device information, cookie, or identifier of any kind is recorded or stored, and there is nothing in it that could be traced back to a visitor.
Children
Wi-Fi Validator is a household utility intended for general audiences and is not directed at children under 13. We do not knowingly collect personal information from children.
Deleting your data
Because your measurements never leave your phone, you are in full control of them:
- In the app, open About → Erase my saved tests to delete every saved coverage test.
- Uninstalling the app removes all of its local data.
- Reset your advertising ID in Android Settings to break any link to previous ad activity.
There is nothing for us to delete on our side, because we never received it. If you would like written confirmation of that, email privacy@wifivalidator.com.
Changes to this policy
If this policy changes, the “Last updated” date above will change with it. Material changes affecting how data is handled will also be noted in the app’s release notes.
