JustShutApp: Smart Call Filter

JustShutApp checks every incoming call against your rules before your phone rings. Calls you do not want arrive without a sound. It starts working the moment you install it and gets sharper as it sees your calls. PEOPLE YOU KNOW ALWAYS RING Anyone in your contacts gets through, every time, whatever else the app thinks. So does anyone you add to your Always allow list. No filter can override that. SILENCED, NOT BLOCKED When JustShutApp decides on its own, it silences the call rather than rejecting it. Your screen still lights up, the call still appears in your call log, and voicemail still works. A wrong guess costs you a moment, never the call. Only rules you set yourself will reject a call outright — because that is your decision, not ours. IT LEARNS THE PATTERN, NOT JUST THE NUMBER Bulk callers buy phone numbers in blocks. When enough numbers from the same block have been reported, JustShutApp quiets the rest of that block, so the next call from that campaign is already handled. Every range it works out is listed in the app with the evidence behind it, and you can remove any of them with one tap. NOTHING LEAVES YOUR PHONE UNLESS YOU SAY SO Your call history, your lists and your contacts stay on this device. There is no account and no sign-in. Once a day the app downloads a shared list of known nuisance numbers — the same signed file everyone gets. Your phone sends nothing to receive it. If it works out that a whole block of numbers is being used for marketing, it asks whether you want to share that block so other people's phones can block it too. You see the exact digits first. It is never a phone number, never your contacts, never your call log. Say no and nothing is sent, and you can change your mind any time in Settings. No analytics. No advertising. No trackers. Nothing about you is ever sold.
