Block spam, scams, and robocalls — without selling your phone number. Spam calls aren't just annoying — they're how scams reach you. CryWolf silences known scammers before they ring, labels suspicious callers so you know what's coming, and lets you report bad numbers with one tap so the next person doesn't pick up. BUILT DIFFERENT Unlike Whoscall and Truecaller, CryWolf doesn't: • Show you ads. Ever. • Sell your data to brokers • Make you upload your address book • Send your phone number to a server in plaintext We use Apple's privacy-first call APIs (CallKit Call Directory + Live Caller ID Lookup with Private Information Retrieval) so even we can't see who's calling you. WHAT YOU GET FREE • Block known spam from a curated, community-sourced list for the country you live in • Add your own block list, unlimited • Tap to block any number — auto-reports back to the community list so others benefit • Caller ID labels for known scam numbers • Zero ads. Zero tracking. Zero address-book upload. CRYWOLF PRO ($5.99 first year, $11.99/year after) • Multi-country (up to 10) — for travelers, expats, dual-eSIM users, or anyone with lines in more than one country. • Continuous community spam list updates from every report, worldwide. HOW IT WORKS 1. Pick the country your line is in. 2. CryWolf downloads the spam list and hands it to iOS's native Call Blocking system. Apple does the actual blocking — we just provide the list. 3. Known spammers don't ring. Unknown callers get a real-time label on your lock screen (Pro). PRIVACY PROMISE • Your contacts are never read. • Your call history is never read. • Your phone number is never sent to our server in plaintext. • We never sell, share, or analyze your data. Subscriptions auto-renew unless cancelled at least 24 hours before the end of the current period. Manage from Settings → [Your Apple ID] → Subscriptions.
