An app in this category needs some permissions and doesn&#039;t need others \u2014 and the permission list often reveals more about the developer&#039;s intentions than the app store description.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This guide is a roadmap for choice. It explains what each permission does, what the red flags are, which applications remain published and are legitimate, and why the promise of &quot;accessing any network&quot; needs to be discarded from the start: entering someone else&#039;s network without authorization is an invasion of a computer device, article 154-A of the Penal Code, punishable by imprisonment from 1 to 4 years.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What permissions does a Wi-Fi app really need?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Location.<\/strong> It&#039;s necessary, and not just a curiosity: on Android, scanning for Wi-Fi networks requires location permission because the list of nearby networks allows the app to deduce your location. Without it, the app can&#039;t even list nearby hotspots.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Access to the network and Wi-Fi status.<\/strong> It is needed to read the available networks and manage the connection.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Storage.<\/strong> It makes sense when the app offers an offline map, because it needs to save the downloaded data.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The red flags<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Accessibility permission.<\/strong> A Wi-Fi app has no reason to do this. It&#039;s the most powerful permission on Android and a favorite of banking trojans because it allows them to read the screen and simulate touches.<\/li>\n\n\n<li><strong>SMS and calls.<\/strong> It has no relation to finding a network. It&#039;s used to intercept authentication codes.<\/li>\n\n\n<li><strong>Contacts.<\/strong> Also unrelated. It&#039;s data collection for resale.<\/li>\n\n\n<li><strong>Screen overlay.<\/strong> It allows you to draw over other applications \u2014 a classic bank fake screen technique.<\/li>\n\n\n<li><strong>Installation of other applications.<\/strong> Absolute red flag in any category.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">On Android, you can check all of this before installing, on the app&#039;s page in the store, and then in... <em>Settings \u2192 Applications \u2192 Permissions<\/em>. It takes a minute and avoids a lot of trouble.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The apps that pass the test<\/h2>\n\n\n\n<h2 class=\"wp-block-heading\">WiFi Map<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The world&#039;s largest collaborative network database, with a 4.3 rating and over 3 million reviews on Google Play. It displays on a map the points registered by users and establishments, with the password when it was published by the administrator, and allows downloading the map for offline use.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The limit is clear and worth repeating: a closed network whose password no one has published will not appear. The app doesn&#039;t discover anything \u2014 it distributes what someone has authorized to be shared.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Instabridge<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Same collaborative model, with a 4.0 rating and over 4 million reviews. Displays nearby registered networks and automatically reconnects you to points you&#039;ve already used, which is practical for daily commutes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Check the developer before installing. Popular apps in this category often have copies with nearly identical names, and it&#039;s precisely in these copies that strange permissions appear.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Opensignal<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">It measures instead of connecting: it maps the quality of nearby mobile and Wi-Fi signals, performs speed tests, and shows carrier coverage. Rated 4.5 and with over 440,000 reviews in the store.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It&#039;s the right tool to decide whether it&#039;s worth searching for a network connection or if mobile data is sufficient at that location\u2014a question many people skip.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Google Maps<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Almost no one thinks of it for that purpose, and it solves many problems. The listings for cafes, restaurants, libraries, and hotels usually include free Wi-Fi among their services, and reviews confirm whether it works. It has a 4.3 rating and over 19 million reviews.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It also has the advantage of allowing you to confirm the exact network name with someone working on-site, eliminating the risk of connecting to a fake point.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Applications from the networks themselves<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Coffee shop chains, fast-food restaurants, supermarkets, and airports have their own apps that automatically authenticate to your home Wi-Fi. These apps come from the network operators, making them the most reliable option for those who frequently visit the same places.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Search for the brand name in the official store and check the developer. The network&#039;s terms of service are also located there.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">FAQ<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Why does a Wi-Fi app ask for location?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Because Android requires this permission to scan for nearby networks \u2014 the list of nearby networks allows the device&#039;s location to be deduced. It&#039;s a system requirement, not a developer choice.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Do these apps show the password for any network?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">No. They only show what has been published by the network owner or the establishment. No legitimate app can discover someone else&#039;s password, and those that promised to do so have been removed from the app stores.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Do the apps work offline?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, maps are useful when you download the area in advance. It&#039;s the most useful resource when traveling, because consulting the map after arriving requires the kind of internet connection you don&#039;t have.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Do I have to pay?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The main features are free. Some sell plans with extras, such as unlimited offline maps or integrated VPN.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Can I use my neighbor&#039;s network if it shows up in the app?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Only if the owner themselves shared the password. Without authorization, it constitutes unauthorized access to a computer system \u2014 article 154-A of the Penal Code, punishable by imprisonment from 1 to 4 years.<\/p>\n\n\n<h2>Why location is required \u2014 and how to limit it.<\/h2>\n<p>This is the permission that generates the most questions in this category, and the explanation is technical: on Android, <strong>Reading the list of nearby Wi-Fi networks requires location permission.<\/strong>. The reason is that the set of visible networks identifies your location with good accuracy \u2014 so the system treats this as location data, even if the application doesn&#039;t request GPS.<\/p>\n<p>In other words, a Wi-Fi map application really needs this permission to function. What can be controlled is the... <em>reach<\/em> her:<\/p>\n<ul>\n<li><strong>Grant permission &quot;during use,&quot; never &quot;always.&quot;.<\/strong> Background access would allow tracking of their movements throughout the day.<\/li>\n<li><strong>Please prefer an approximate location.<\/strong> Once the app accepts it \u2014 that&#039;s all you need to do to find a nearby network.<\/li>\n<li><strong>Revoke after use.<\/strong>, if it&#039;s for occasional use during a trip.<\/li>\n<li><strong>Check the activity dashboard.<\/strong> Which apps accessed your location in the last 24 hours?.<\/li>\n<\/ul>\n\n<h2>Permits that have no justification whatsoever.<\/h2>\n<ol>\n<li><strong>Accessibility service.<\/strong> It allows you to read screen content and simulate touches. This is the mechanism used for bank fraud, and no Wi-Fi app needs it. Request = uninstall.<\/li>\n<li><strong>Device administrator<\/strong>, which makes uninstallation itself difficult.<\/li>\n<li><strong>Contacts and SMS.<\/strong> There is no Wi-Fi function that depends on your schedule.<\/li>\n<li><strong>Microphone and camera<\/strong>, Unless a QR code is scanned \u2014 and then only the camera can be used, on demand.<\/li>\n<li><strong>Access to all files.<\/strong> A network map doesn&#039;t need to scan your entire storage.<\/li>\n<li><strong>Screen overlay<\/strong>, which allows you to draw over other applications.<\/li>\n<\/ol>\n<p>It&#039;s worth checking all of this out. <strong>before installing<\/strong>, In the store&#039;s listing, along with the data security section\u2014where the developer declares what data it collects and whether it shares it with third parties for advertising.<\/p>\n\n<h2>What does the collaborative base know about you?<\/h2>\n<p>Wi-Fi mapping apps work because users register networks and passwords. This means the service accumulates data that is sensitive by nature. <strong>where people have been and what networks they&#039;ve connected to.<\/strong>.<\/p>\n<p>What to check in politics before contributing:<\/p>\n<ul>\n<li><strong>If the app sends automatically<\/strong> Saved networks on your device \u2014 including your home network, which is password protected. Many devices offer this option, and it should be turned off.<\/li>\n<li><strong>If the connection history is retained<\/strong>, And for how long?.<\/li>\n<li><strong>If there is sharing with third parties<\/strong> for advertising or market analysis.<\/li>\n<li><strong>Is it possible to delete the account?<\/strong> And the real data\u2014deleting the app doesn&#039;t delete anything on the server.<\/li>\n<\/ul>\n<p>Under the LGPD (Brazilian General Data Protection Law), you have the right to request a copy and deletion of your data, and this request is made to the service provider. It&#039;s important to exercise this right before uninstalling, not after.<\/p>\n\n<h2>Never share your network password.<\/h2>\n<p>It seems obvious, and it&#039;s the most common mistake people make when installing these apps. Publishing your home or work network password on a collaborative platform means:<\/p>\n<ul>\n<li><strong>Anyone nearby can get in.<\/strong>, And you won&#039;t know who is online.<\/li>\n<li><strong>All traffic goes through your contract.<\/strong>, and the responsibility for its use rests with you.<\/li>\n<li><strong>Household devices are left exposed.<\/strong> Printer, camera, network storage, smart devices.<\/li>\n<li><strong>At work, it&#039;s a policy violation.<\/strong> in most companies.<\/li>\n<\/ul>\n<p>To grant access to a visit, the correct path is already in the system: <strong>Share via QR Code<\/strong>, which the device itself generates from the connected network, or create a <strong>visitor network<\/strong> on the router, isolated from the main network.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Choosing a free Wi-Fi app is less about the size of its user base and more about what it requires to function. Location, network status, and storage make sense; accessibility, SMS, contacts, and screen overlay do not\u2014and these are exactly the permissions used by banking trojans.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">WiFi Map, Instabridge, Opensignal, Google Maps, and the networks&#039; own apps pass this test and remain published in the official store. Install only from there, check the developer, and immediately discard any promises of accessing other networks.<\/p>\n\n\n\n<h2>Read too<\/h2>\n<ul>\n<li><a href=\"https:\/\/crismob.com\/en_gb\/application-to-clean-cell-phone-memory-see-how-to-make-your-device-faster\/\">Clearing your phone&#039;s memory: files you shouldn&#039;t delete<\/a><\/li>\n<li><a href=\"https:\/\/crismob.com\/en_gb\/meditation-and-well-being-apps-which-is-the-most-ideal-for-you\/\">Meditation Apps: Which One to Choose and What They Don&#039;t Do<\/a><\/li>\n<li><a href=\"https:\/\/crismob.com\/en_gb\/apps-to-find-free-wi-fi\/\">Free Wi-Fi While Traveling: How to Prepare Before Leaving Home<\/a><\/li>\n<li><a href=\"https:\/\/crismob.com\/en_gb\/find-out-which-apps-connect-you-to-wi-fi-without-a-password\/\">Shared Wi-Fi Password: How the Collaborative Base Works<\/a><\/li>\n<li><a href=\"https:\/\/crismob.com\/en_gb\/app-to-find-wifi-anywhere\/\">Slow Wi-Fi at Home: How to Diagnose and Where to Find a Network Outside the Home<\/a><\/li>\n<li><a href=\"https:\/\/crismob.com\/en_gb\/app-to-find-free-wifi\/\">Free Wi-Fi: How to Find a Public Network and Browse Safely<\/a><\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>Antes de escolher um aplicativo para encontrar Wi-Fi gr\u00e1tis, vale olhar para um detalhe que quase ningu\u00e9m confere: quais permiss\u00f5es ele pede.
