Phone numbers and rules are stored on this iPhone and shared only with the app's call and message extensions. We do not read your Contacts or call history. Message content is checked on the device and is not saved or sent to a server. You can remove each rule in My rules.
Advertising
The main app uses Google AdMob. Google may process device, IP address, ad interaction and diagnostic data to serve ads, prevent fraud and meet legal requirements. We request non-personalized ads. Where required, Google presents consent choices. You can revisit available choices from Settings. Call and message extensions do not contain the advertising SDK.
Backup in your iCloud
When you enable backup or tap Back up now, numbers, keywords, and country settings are saved in your iCloud Drive under Apple’s policies. They are not sent to a QuietCall server. You can turn off automatic backup and delete the backup in Files.
Optional support
Apple processes payments. QuietCall verifies the purchase with StoreKit and does not receive your card details. Tips do not unlock features and cannot be restored as an entitlement.
For advertising data details, see Google’s policy. This site is hosted by Cloudflare, which may process IP addresses and technical request data for delivery and security. This site includes no ads or analytics tools.
Setup & how it works
1. Add call rules in My rules.
2. Open Settings → Apps → Phone → Call Blocking & Identification. On iOS 17, Phone is directly in Settings.
3. Enable QuietCall.
4. Return to My rules and tap Apply call list again.
For messages: open Settings → Apps → Messages → Unknown & Spam (the name varies by iOS version). Enable filtering of unknown senders and select QuietCall as the SMS filter. Only one message filter can be selected. Add sender or word rules in My rules.
No rules are enabled for you automatically. Wide patterns can block wanted numbers. Hidden numbers, FaceTime, iMessage and calls handled by other apps are outside this app's control. iPhone does not give QuietCall a call history or blocked-call count.
Allowed numbers come first
QuietCall always excludes allowed numbers from its call blocking and message filtering.
Block 070-7744, but allow 070-7744-1234: that number is excluded. Its messages are allowed even when a keyword matches.
What iPhone controls
QuietCall cannot override iPhone's blocked contacts, carrier filters or other calling apps. An allow entry cannot force those systems to accept a call. Hidden caller IDs cannot be matched. iPhone controls how numbers in Contacts are treated.
Message filtering covers eligible SMS/MMS from unknown senders. It does not filter iMessage or messages from contacts. Alphanumeric sender names cannot match a numeric allow entry.
The list was not fully applied. An older list or only part of this list may remain. Check Settings and apply again.

These are not confirmed spam lists. Caller IDs can be spoofed and legitimate calls may be blocked. Allowed numbers always come first. Guidance is updated with app releases.
