About
About the app and its publisher
Short version: Data Monitor is a network meter and data usage analyser for Android, it has been on Google Play since 2017, it is free with advertising and optional purchases, and this website is run by the people who publish it.
The app
Data Monitor: Simple Net-Meter puts live upload and download throughput in the Android status bar and analyses where mobile data goes: against the monthly quota you enter, day by day, and app by app. Around those two jobs sit a list of open network connections, a ping watch list and a Wi‑Fi scanner.
It has been published on Google Play since April 2017 and is still updated; the current release requires Android 6.0 or later. At the time of writing the listing shows more than a million installs and a 4.4 rating from around 16,400 ratings. Those numbers move, and the listing is always the authoritative version of them.
The features are described in more detail on the home page, and the guide covers setup and troubleshooting.
Who publishes it
The app and this website are published by KF Software House, a software developer based in Hong Kong that has been publishing Android utilities on Google Play for over a decade — calendar, network and system tools, of which Data Monitor is one.
Google verifies the identity and contact details of Play developers and publishes what it verified in the About the developer block on every listing. For this app that block is on the Play listing, alongside the full registered postal address and phone number. This site carries the business identity, the city and a working email rather than repeating the whole record here — but nothing is hidden, and the verified version is one click away.
How the app is funded
It is worth being blunt about this, because it is the honest answer to “what is the catch?”.
- Advertising. The free version shows ads inside the app — the Google Play listing carries a Contains ads badge. That advertising is what pays for a free utility, and it is also the reason the Play data safety declaration lists data shared with third parties for advertising purposes. Both are set out plainly in the permissions and data section.
- Optional purchases. The listing carries an In-app purchases badge, priced by Play at $2.99–$4.49 per item, covering widgets and selected modules. These are one-off purchases, not a subscription, and the meter and usage analysis work without them.
There is no paid tier of this website, no newsletter that turns into an invoice and no payment taken anywhere on it. The only transaction that exists happens on Google Play.
What this website is for
A store listing gives you a few hundred words and a row of screenshots. It has no room to explain why a data monitor needs location permission, what the difference is between the meter and the usage analyser, why the figures will never exactly match a carrier bill, or what the data safety declaration actually means for someone installing the app. That is what these pages are for.
What the site deliberately does not do:
- It does not host the app or offer an APK. Google Play is the only install route, and every download button here links there.
- It does not take payments, collect registrations or run a login.
- It does not publish invented reviews, awards or user testimonials.
- It does not claim any affiliation with Google. Android, Google Play and the Google Play logo are trademarks of Google LLC.
Contact
Correspondence goes through the contact details Google holds and publishes for this publisher, rather than through an address maintained on this website. Google verifies those details against documents as part of Play developer verification, which makes them the reliable route rather than the roundabout one.
| What about | Where to find the address |
|---|---|
| App support, bug reports, feature requests | The Developer contact section of the Play listing |
| Privacy, data protection and deletion requests | The same contact, and the app’s own privacy policy, which sets out how requests about the app are handled |
| Legal and trademark matters | The registered email, postal address and phone number in the About the developer block of the Play listing |
Replies are written in Hong Kong office hours, so allow for the time difference.
When reporting a problem with the app, include the phone model, the Android version and the app version. Almost every answer depends on those three, and asking for them afterwards costs a day.
Legal documents
Three separate documents govern three separate things, and it is worth knowing which is which:
- This website’s privacy policy — what happens when you visit these pages.
- The app’s privacy policy — what happens inside the app on your phone. Also linked from the Play listing.
- Terms of use for this website — the rules for these pages. Use of the app itself is additionally governed by the Google Play Terms of Service.
