In short
MaxBars (com.mrgg.maxbars) is an app by MrGG. No account, no ads, no analytics, no trackers. We, the developer, receive nothing about you from the app; the only thing we ever receive is an email you choose to send us. What MaxBars reads and saves for its features stays on your phone. Only three things go online: the speed tests and Wi-Fi check-ups you start (to Cloudflare), and Google Play’s purchase service, which tells MaxBars whether you have Pro (Google Play’s billing library also reports some technical details to Google; see below). We don’t sell or share your data.
What MaxBars saves on your phone
Your modes and settings, which SIM to use and the mode your phone was on before; your speed test results (up to the last 50); the devices found on your Wi-Fi, the names you give them and, for Wi-Fi Guard, which devices each watched Wi-Fi has had; your data pack, alerts and today’s data use count; the games you pick for Game Mode; and whether you have Pro. They are kept in MaxBars’ private storage, never sent to us or anyone, left out of backups and phone transfers, and deleted when you uninstall MaxBars.
Mobile network
Network type, signal strength, carrier name and SIM slots, to show your signal and switch modes. MaxBars has no phone, contacts or SMS permission and never looks at your calls, messages or contacts. Keep My Mode and Game Mode only check whether a call is going on (from Android’s audio state), so they don’t switch modes during a phone call.
One-tap switching (Accessibility)
One-tap switching uses Android’s Accessibility feature only for the phone’s hidden network menu (in the Phone and Settings apps), and only after you agree in the app. It acts only after you choose a mode or run Best mode, when Keep My Mode puts yours back, and when Game Mode holds one mode in a game you picked, then puts your usual mode back (also after a restart). Keep My Mode asks first unless you choose Fix It Automatically, and Game Mode is off until you turn it on. It also checks which mode your phone is on at setup, and when you tap Read My Phone Again. In that menu it reads only the SIM and network mode choices, which ones are selected, and whether the menu shows 5G. MaxBars uses them to set your mode, check that it worked and show it to you. It also checks which windows are open on screen, only to find that menu and to see whether the notification shade covers it; if it does as a switch starts, MaxBars pushes the shade back up (Android 12 and newer). What it saves stays on this phone. It reads nothing else on your screen or in other apps, and shares nothing. You can turn it off any time in Settings › One-Tap Switching.
Wi-Fi and nearby networks
The name (when Android shows it), signal, band, channel, Wi-Fi type, link speed and security type of the Wi-Fi you’re on, and the local addresses of your router and this phone on it. To count nearby networks per channel, the check-up uses the Nearby devices permission on Android 14 and newer (never for location). Android 13 and older only list Wi-Fi networks to apps with location access, so MaxBars asks for it there, only when you run the check-up, and also reads your router’s Wi-Fi address to leave your own network out of the count. While location is allowed on Android 13 and older, Android also shows MaxBars your Wi-Fi’s name, which MaxBars shows on the Wi-Fi tab. MaxBars never reads or stores your location.
Apps on your phone
MaxBars reads the list of apps with a launcher icon to let you pick games for Game Mode, to show which apps used data in Data Guard, and to check whether your router maker’s app is installed (Make My Phone First). The list stays on this phone.
Usage access (Pro, only if you turn it on)
Data Guard reads Android’s own count of mobile data per app. Game Mode checks which app is open, to know when your game starts. Android calls this Usage access; you turn it on in the phone’s settings and can turn it off there any time. MaxBars never sees what you do inside other apps, and none of it leaves the phone.
Status icon (Pro, only if you turn it on)
A small always-on service keeps the icon next to the clock up to date. It reads the mobile network and its signal, the carrier name, which connection is in use and Android’s data counters, all on the phone, and stops when you turn the icon off.
Camera, pictures and notifications
The camera, or a picture you choose, is used only to read a Wi-Fi QR code, on the phone; nothing is recorded or kept. A Wi-Fi name and password from a code are shown to you and not saved; the password is copied only when you tap Copy Password, or Join This Network on phones where MaxBars can’t add the network for you. Notifications are only for the status icon, Keep My Mode and Game Mode notes, and the Wi-Fi Guard and Data Guard alerts you turn on. Each permission is asked only when you use that feature.
Devices on your Wi-Fi
The Devices page, and Wi-Fi Guard (Pro, about every half hour, only if you turn it on), talk only to devices on your own Wi-Fi, using standard home-network protocols (Bonjour, UPnP, NetBIOS and your router’s own name list). What they learn (device names, addresses and types) stays on this phone. Nothing goes online.
What goes online
Speed test and Best mode, when you start them: random test data is downloaded from and uploaded to Cloudflare’s speed test servers (speed.cloudflare.com) over HTTPS. Wi-Fi check-up, when you start it: a few DNS questions for cloudflare.com go to Cloudflare’s public DNS (1.1.1.1) to time the answers; they contain nothing about you. Like any website you visit, Cloudflare sees your IP address and basic connection details. MaxBars sends Cloudflare nothing else, and we receive none of it. Cloudflare’s privacy policy: cloudflare.com/privacypolicy.
Google Play and MaxBars Pro
Google Play handles all purchases; MaxBars never sees your payment details. When you open MaxBars, it asks Google Play whether you have Pro (and for Pro’s prices). While one-tap switching, the status icon, Wi-Fi Guard or Data Guard alerts are on, it also asks whether you have Pro at most about every 12 hours. MaxBars saves only that answer on this phone. Google Play’s billing library, which is built into MaxBars, also sends Google technical information about these requests, such as whether they worked, the app version, your phone model and Android version, language and region settings, network type and mobile carrier code. Google handles it under its own privacy policy (policies.google.com/privacy); we don’t receive it. To manage or cancel a subscription, open Google Play › Payments & subscriptions › Subscriptions. Uninstalling MaxBars doesn’t cancel it.
Emails you send us
Send Feedback opens your email app with a message to ziaul.wowturn@gmail.com and your phone model and Android version in the subject, which you can change. If you send it, we receive your email address, what you wrote and anything you attach. We use it only to reply and fix problems, keep it only as long as needed for that, and delete it whenever you ask.
How your data is protected
What MaxBars saves is kept in its private storage, which Android keeps away from other apps, and is left out of backups and phone transfers. Speed tests use encrypted connections (HTTPS). Check-up DNS questions carry no personal data, and device discovery stays inside your Wi-Fi.
Keeping and deleting your data
Data on your phone stays until you change it, until MaxBars replaces old entries (it keeps the last 50 speed tests and forgets the Wi-Fi networks and devices seen longest ago), or until you delete it: phone Settings › Apps › MaxBars › Storage › Clear storage, or uninstall MaxBars. Permissions, Usage access and Accessibility can be turned off any time in the phone’s settings. We hold no data about you from the app, so there is nothing on our side to delete; write to us and we’ll delete any email you sent. For what Cloudflare or Google handle, see their privacy policies.
Children, your rights and changes
MaxBars is not made for children. Wherever you live, you can ask us what we hold about you (at most, your emails) and ask us to delete it; in the EU or UK you can also complain to your data protection authority. If MaxBars’ data practices change, we’ll update this policy and its date, and say so in the app and on its Google Play page first.
