NoSnoop: WiFi Security Checker

■ What NoSnoop does
• Checks the Wi-Fi you're connected to and tells you, in seconds, whether it looks Safe, needs Caution, or is a Danger.
• Six checks run on your phone: encryption, look-alike (evil twin) networks, sign-in pages, DNS tampering, signs of eavesdropping, and risky open ports on the router.
• See the Wi-Fi networks around you, with a verdict for each, before you connect.
• With NoSnoop Premium, get a notification the moment your phone joins an unsafe Wi-Fi.

■ The six checks
• Encryption: open networks and old WEP locks are flagged as Danger; old WPA as Caution.
• Look-alike networks: warns when a network with the same name appears both with and without a password nearby, a common trick of fake hotspots.
• Sign-in pages: tells you when a hotel or café network uses a sign-in page, where what you type may be seen.
• DNS tampering: checks whether address lookups on this network are being redirected.
• Signs of eavesdropping: checks whether secure connections are being intercepted, and whether a proxy or an extra certificate has been added to your phone.
• Router ports: checks whether the router leaves risky doors open, such as telnet or an unencrypted admin page. NoSnoop never tries to log in.

■ Before you connect
At the airport, a café, or a hotel, open the Nearby tab to see the networks around you. The top one (the network you're on, or the strongest) always shows its verdict for free. Premium shows the verdict for every network.

■ Honest about what it can't see
NoSnoop only says what an Android app can actually check. If something can't be checked, it says "Unknown" instead of guessing. Some attacks, such as ARP spoofing on the local network, can't be detected by any Android app, so a "Safe" verdict is a good sign, not a guarantee.

■ No ads. No VPN upsell. No scare tactics.
NoSnoop shows no ads and doesn't try to sell you a VPN. It never counts up "threats" to frighten you into paying.

■ Your Wi-Fi stays on your phone
There is no account and no sign-up. Wi-Fi names, the networks around you, and every check result stay on your phone; we don't receive them. The location permission is needed only because Android requires it to read Wi-Fi names; NoSnoop never stores or sends your location. We use Google Analytics for anonymous usage statistics, and Google Play and RevenueCat to handle Premium.

■ Pricing
All six checks of the Wi-Fi you're connected to, and the verdict for the top nearby network, are free. NoSnoop Premium (monthly, auto-renewing; price shown in Google Play) adds verdicts for every nearby network and the instant notification when you join an unsafe Wi-Fi. Billing and cancellation go through Google Play; refunds follow Google Play's policy.

■ NoSnoop might not be for you if:
• You want a VPN (NoSnoop checks networks; it doesn't encrypt your traffic)
• You want to see every device connected to your home Wi-Fi (not yet available)
• You want a speed test (not yet available)

■ Requirements
• Android 10 or higher
• Location permission is optional; without it, network names and the nearby list aren't shown
