Contacts-only call blocker for Android with local, privacy-first filtering
Block every unsaved caller automatically, allowing inbound calls only from numbers stored in your phone, and review rejections later in a local log. Bloqueador de Chamadas, by Vinicius L Pinheiro, is an Android utilities tool that uses the platform’s native screening service. It keeps all contact lookups and call history on-device, offers silent or discrete notifications, and targets users who face frequent spam or telemarketing and want a privacy-centered, low-footprint filter.
How strict is the blocking policy in practice?
The app enforces a contacts-only policy: it permits calls from numbers saved in the device address book and rejects others automatically. That behaviour removes the need to manage blacklists, because the whitelist is simply your local contacts. For users who want every unknown incoming call rejected, the app provides that strict mode by default and ensures calls from saved contacts always pass through.
What is the system impact and integration model?
Bloqueador de Chamadas integrates with Android’s native screening service rather than running continuous background processes, which reduces active resource use. Because it relies on built-in platform hooks to manage calls, the app operates with standard permissions to access contacts and call control. The reliance on native services also means it does not require external servers to check numbers.
Is it safe and how does it handle privacy?
All contact verification and call logging occur locally on the device, so no contact data is uploaded or shared, according to the developer. The app keeps a local history of rejected calls and offers configurable alerts, including silent mode and discrete notifications, so logs remain on-device and notification behaviour can match user privacy preferences.
Firm privacy-focused tool for users who accept a strict whitelist trade-off
The app suits Android users who want on-device filtering and minimal runtime overhead; it enforces a contacts-only policy reliably and stores rejection history locally. Expect a rigid blocking model that can omit legitimate unknown callers, so check the local blocked-call log periodically to recover missed important numbers. For anyone prioritizing local processing over flexible caller heuristics, the app delivers a focused, low-interaction screening option.
