HK Call Guard

[Hong Kong's First Privacy-First Spam Call Blocking App]

Tired of being harassed by daily telemarketing and scam calls? HK Call Guard is a spam call blocking app made for Hong Kong people, the only one with code guaranteeing it will never upload your contacts.

━━━ Why Choose HK Call Guard? ━━━

🔐 Privacy First (Unique in its Class)
In 2024, the Consumer Council revealed that CallApp and Truecaller automatically uploaded all users' contacts to a public database. HK Call Guard's code does not request contact permissions, making it technically impossible to upload your contacts. This is not a promise, but a code guarantee.

⚡ Speed ​​First
Instant local comparison within 0.1 seconds of receiving a call, no internet query required, ensuring no missed calls due to network latency.

🇭🇰 Hong Kong Exclusive Data
Integrates with HKJunkCall's local Hong Kong crowdsourced database (recognized by the Hong Kong Police Force's "Good Citizen Award"), targeting common telemarketing, scam, and harassing calls in Hong Kong.

📷 Screenshot Scam Scanner (Unique Among Its Kind) Received a suspicious SMS? Take a screenshot, and the app automatically uses AI to identify the number and scam keywords, reporting all suspicious numbers with one click—completely offline.

🔔 One-Click Notification Bar Handling After blocking a call, "Confirm Report" and "Add to Whitelist" buttons appear directly in the notification bar. No need to open the app; one action completes the process.

💬 SMS Spam Filtering Scan SMS content to identify common Hong Kong scam keywords such as "investment," "loan," and "prize," providing instant alerts.
