Why is the app free and ad-free?

It is developed by a developer, Camille Bouvat, who had had enough of receiving unwanted calls and SMS. The app is developed under the GNU GPLv3 open source license.

The app is free for the general public, funded by donations. Saracroche offers specific features for businesses and organizations, which help fund the development.

Its goal is to offer a service that lets everyone be protected from unwanted calls and scams.
