Frequently Asked Questions

Yes, if you prioritize decentralization and privacy. Unlike centralized apps like WhatsApp, RetroShare has no single point of failure and keeps your data on your device. It lacks public discovery features but offers full control over your communication.

RetroShare is open-source software under the GNU GPLv2 license. It is 100% free to use, modify, and distribute with no subscription fees or hidden costs.
