What it is
Kalkan is a privacy-first iPhone app for filtering spam. It sorts bulk spam, scam and betting messages into Junk or Promotions while keeping verification codes and transaction alerts in your inbox, and it can block individual numbers or whole number ranges.
Everything runs on the device: there are no servers, no accounts and no data collection.
Stack
Built with Swift 6 and SwiftUI on iOS 26 APIs. The SMS filter uses the IdentityLookup framework and call blocking uses CallKit. App Store release is upcoming.
