FREQUENTLY ASKED QUESTIONS

Frequently Asked Questions

Clear answers regarding Blockify's on-device privacy, call screening mechanics, and VIP licensing.

Never. The READ_CONTACTS permission is executed strictly inside your local device memory to verify if an incoming caller is in your address book (Whitelist). Blockify does not operate remote servers to ingest, analyze, or monetize your contact book.

Conventional caller ID apps require mandatory account registration and systematically upload your entire contact list to remote cloud databases for reverse lookup and ad targeting. Blockify is 100% On-Device: no account, no cloud telemetry, zero personal data harvesting, and total privacy for executive communication.

When expecting a delivery from courier services (FedEx, DHL, UPS) or food delivery drivers (DoorDash, UberEats, Deliveroo), simply toggle Courier Pass in the app or via the Android Quick Settings Tile. All incoming calls are permitted for 30 minutes, after which Strict Mode defense re-engages automatically without requiring manual action.

Zero data usage and negligible battery impact. Because there is no background cloud synchronization or continuous server polling, Blockify operates passively through the Android Telecom layer and only executes lightweight SQLite queries in milliseconds (0.02s) when a call is actively arriving.

Emergency service calls (such as 911, 112, 999) are managed directly by the Android operating system and are never blocked by Blockify. If you are expecting calls from hospitals, clients, or service providers from unsaved numbers, you can temporarily enable Courier Pass or add their specific area code prefix to your whitelist rules.

You can specify dial code prefixes (such as +234*, +1800*, 021140*) to instantly eliminate thousands of robocalling numbers belonging to known telemarketing clusters or offshore scam rings before your phone rings.

Yes, 100% Lifetime. The VIP license (blockify_vip_lifetime) is a single, one-time payment with zero recurring subscription fees. It is permanently tied to your Google Play account. When you change or reset your Android device, simply install Blockify using the same Google account and your VIP Lifetime status will automatically restore.

Blockify is optimized for Android 8.0 through Android 15+. It runs natively across Google Pixel, Samsung Galaxy, Xiaomi/Redmi, OnePlus, Oppo, Vivo, Motorola, and other Android OEM devices supporting Android Telecom Call Screening.
