GreerGuard Phone – Anti-Popup

GreerGuard keeps your Android device clean from malicious, invasive, and unwanted apps - targeting the relentless popup ad apps that appear, and interrupt your regular phone usage. The impossibility to uninstall those apps is what GreerGuardian (paid) aims to provide the service of: when an app interrupts your content, you'll be alerted and given the opportunity to uninstall the app in two clicks!

𝗚𝗿𝗲𝗲𝗿𝗚𝘂𝗮𝗿𝗱 𝘀𝗰𝗮𝗻𝘀 𝗳𝗼𝗿:

▸ Hidden and disguised apps running without your knowledge
▸ Apps installed from outside trusted channels
▸ Apps holding dangerous or unnecessary permissions
▸ Adware, popup generators, and notification spammers
▸ Apps with access to your calls, messages, microphone, or camera that have no reason to need it
▸ Apps abusing elevated device privileges

Each app gets a risk score - Low, Medium, or High - based on how many signals it triggers and how severe they are.

𝗙𝗿𝗲𝗲

Every GreerGuard user gets access to manual scanning, per-app permission review, force-stop, one-tap uninstall prompts, and a trusted apps list so safe apps are never flagged again. No subscription required.

𝗣𝗮𝗶𝗱

Upgrade to GreerGuardian for real-time protection that runs around the clock. GreerGuardian scans your device as you use it, stopping threats the moment they install or activate, before they can cause harm or headaches.

𝗚𝗿𝗲𝗲𝗿𝗚𝘂𝗮𝗿𝗱𝗶𝗮𝗻 𝗶𝗻𝗰𝗹𝘂𝗱𝗲𝘀:

▸ Real-time monitoring that catches threats the moment they appear
▸ Automatic detection and removal of popup and ad-generating apps
▸ Detection of apps attempting to persist or communicate in the background without your permission
▸ Full-screen threat alerts, even on a locked device - similar to an incoming call notification
▸ Persistent background protection that keeps running even if your device tries to stop it
▸ Complete history log of flagged activity, trusted apps, and protection changes

𝗦𝗮𝗳𝗲 𝗕𝗿𝗼𝘄𝘀𝗶𝗻𝗴 (DNS filter)

GreerGuard includes an optional DNS filtering feature called Safe Browsing. When enabled, it uses Android's VpnService API to create a local VPN tunnel on your device. This tunnel intercepts DNS queries - the lookups your apps make before connecting to any server - and blocks known tracker, advertising, and malware domains before a connection is ever established.

All DNS filtering happens entirely on your device. No internet traffic, browsing content, or app data is routed through any external server. The local tunnel is used solely to inspect and filter DNS queries, forwarding allowed domains to Cloudflare's DNS resolver (1.1.1.1). Your data is never collected, sold, or shared as part of this feature.

You can enable or disable Safe Browsing at any time from within the app. It has no effect on your internet speed or connectivity for allowed traffic.

GreerGuard has no ads. Just protection.


GreerGuard does not have the capability to prevent fullscreen, possibly misleading ads on websites while browsing on your web browser without the GreerGuard extension.
