About this app
IDKY Call Blocker (I Don't Know You) is the essential utility designed to give you back your peace of mind. Tired of constantly receiving calls from call centers, telemarketers, or unknown numbers?
IDKY does one thing, and does it perfectly: it allows calls to ring only if the number is saved in your contacts. Everything else is blocked automatically.
How does it work?
Once set as your default call screening app, IDKY intercepts incoming calls. If the number is in your contacts, your phone will ring normally. If the number is unknown, the app will silently reject the call before your phone even starts ringing.
Key Features:
• Total & Silent Blocking: No distractions. Calls not in your contacts are instantly rejected.
• Local Call Log: Keep track of blocked numbers with a clean, organized history inside the app.
• Quick Swipe Actions: Easily swipe any row to copy the blocked number, save it to your contacts, or delete it from the history.
• Multi-Selection: Long-press to select multiple calls and delete them with a single tap.
• Quick Toggle: Pause the protection with a single tap when you're expecting an important call from a delivery driver or a new number.
Why choose IDKY Call Blocker?
Unlike traditional Caller ID apps that often still let your device ring to show you who is calling , IDKY takes a drastic root approach: if I don't know your number, you don't disturb me.
Guaranteed Privacy (Offline-First)
Your security comes first. The app requires access to your contacts exclusively to compare incoming numbers in real-time. No contact, call log, or phone number is ever sent to external servers. All screening happens offline, directly on your device.
Take back control of your time and your smartphone. If you don't know them, block them with IDKY!
