CALLER INTELLIGENCE THAT STAYS ON YOUR PHONE

Spam Call Blocker: Caller ID is a private, offline-first caller intelligence and scam defense toolkit. Look up any number, understand its risk through transparent on-device signals, block callers on your own terms, and document unwanted calls — with no account, no contact upload, and no crowdsourced database.

WHAT MAKES THIS APP DIFFERENT

- Transparent by design: every risk assessment shows the reasons behind it, not just a score you have to trust.
- Private by architecture: your lookups, flags, notes, and rules are stored only on this device.
- Honest by default: if something cannot be determined on-device, the app says so instead of guessing.

RISK SIGNALS — KNOW WHY, NOT JUST WHAT
Analyze any number entirely on your device. The app checks number format, line type, region match, premium-rate patterns, and your own history with the caller, then explains each signal in plain language. Tap "Why these signals" to see exactly how the result was formed.

SHIELD RULES — BLOCK ON YOUR TERMS
Build your own blocking list with exact numbers and rules you define. Everything is saved on your device and applied through the iPhone's native Call Blocking and Identification system.

NUMBER LOOKUP AND HISTORY
Search any number with the correct country code, paste from the clipboard, or use the built-in keypad. Your lookup history, starred numbers, and personal tags stay organized and private.

MY REPORTS AND MY NOTES
Flag suspicious numbers and attach private notes. Your flags feed your own Risk Signals and Device Protection — they are yours alone and never shared.

BACKUP AND PORTABILITY
Export your reports, notes, and block list to a file you control, and restore them anytime. Your data is portable because it belongs to you.

HOW BLOCKING AND IDENTIFICATION WORK
Calls are blocked and labeled using only: numbers you add to your block list, rules you create, numbers you flag, and offline number-pattern checks. There are no shared, third-party, or crowdsourced spam lists. To enable device-level blocking, turn on this app's directory under Settings > Phone > Call Blocking & Identification.

PRIVACY, BY DESIGN
Your lookups, reports, notes, and rules never leave your device. No account is required. Your contacts are never uploaded; names shown come only from your own address book or on-device analysis.

Know who is calling — without giving up your privacy.

DISCLAIMER

Risk Signals are informational estimates generated on this device from number patterns and your own saved data. They do not guarantee that any caller is safe or unsafe, and a flag does not prove wrongdoing — always use your own judgment. Some caller details (carrier, city, or name) may be unavailable because no crowdsourced database is used. Call blocking works only after you enable the app's directory in iOS Settings and applies only to the numbers and rules you set; no app can stop every unwanted call.
