| Privacy | The README says offline features collect no data; for online features the API server sees the IP address, TLS/TCP fingerprints, and reported number. | Whoscall says call-related information is de-identified and that it does not share or use unencrypted data. |

Whoscall
Whoscall identifies incoming callers in real time and blocks spam and scam calls on Android and iOS. Its AI checks phone numbers, links, and screenshots against trusted data to flag possible risks. The app also offers Scam SOS, with one-tap access to bank hotlines and online scam reports, and Voice Alerts that warn about suspected scam calls; both features vary by region. Users can report scams and earn points and badges, contributing information to the community. Whoscall says its number database holds more than 2.6 billion entries. The free plan includes caller ID, call blocking, checks for numbers, links, and screenshots, and scam reports and rewards. Paid Individual, Duo, and Family plans add account sharing, database updates, an SMS assistant, ad-free use, and automatic spam blocking; Live Caller ID Plus is limited to iOS 18 or later. Individual costs $27 a year. Business customers can apply for Verified Business Number, which displays a verified company name and logo and requires a minimum six-month purchase.
