Freezer

Freezer lets you "freeze" apps — instantly cut off their internet access and
silence their notifications — without uninstalling them. Take back your focus,
save battery and data, and stop background apps from phoning home.

KEY FEATURES
• Freeze any app with one tap — its network access is blocked instantly
• Notifications from frozen apps are silenced until you thaw them
• Schedules & profiles (e.g. Work / Sleep) to auto-freeze sets of apps
• Activity log and stats for what was blocked
• Home-screen widgets and a Quick Settings tile for fast toggling

HOW IT WORKS — LOCAL VPN (please read)
Freezer uses Android's VpnService to create a LOCAL, on-device VPN. This is the
core feature and the only way an app can block another app's network access
without root. Important:
• The VPN runs entirely on your device. It does NOT connect to any external or
remote VPN server.
• No traffic is routed off your device. Packets from frozen apps simply enter a
local tunnel and are dropped.
• Freezer does NOT read, log, collect, store, or transmit your network traffic,
browsing, or any personal data.
• Only apps you choose to freeze are affected. Everything else bypasses the VPN.
• You grant the VPN permission via Android's standard dialog and can revoke it
anytime in Android Settings.

PERMISSIONS
• VPN (VpnService): required to block frozen apps' network access (local only).
• Notification access: to silence notifications from frozen apps.
• Usage access (optional): only for auto-freeze when an app goes to background.

Your privacy is the whole point: everything stays on your device.
