Fight the Power Using KDE Applications.
Developed by humans, for humans
KDE e.V. is a German non-profit foundation, and our software is primarily developed by volunteers from all over the world. Unlike our competitors, we don't seek to make money, but instead seek to make the world a better place. We envision a world where monopolistic corporations and repressive governments don't have too much power over our digital lives. We actually care about data privacy and digital well-being, and we fight for them.
KDE supports the FEEP and BE4FOSS programs to help free and open-source communities produce more environmentally friendly software. The projects provide communities with guidelines and support to optimize software to be more energy efficient and have a longer life-span.Learn more

End to End Encryption
Everyone has a right to privacy, but for activists, ensuring the privacy and security of communication can become a matter of life and death.
Keep your emails private with KMail
KDE's email client KMail provides world-class GnuPG integration, which makes it easy to encrypt your emails. GnuPG is a global standard which was for example used by Edward Snowden to communicate with journalists.
KDE also offers Kleopatra, an approachable app to manage multiple cryptographic certificates.
Keep your messages private with NeoChat
For real-time end-to-end encrypted communication, KDE has developed NeoChat, a client for the decentralized and secure messaging protocol: Matrix. It's secure and contains many features that make talking with your community a breeze, including support for multiple accounts, stickers, emoji reactions, and more.
Keep your files private with Plasma Vault
Plasma Vault lets you add another layer of security by storing files and folders in a super-secure encrypted container. Plasma Vault can optionally disable WiFi and Bluetooth when unlocked, providing extra protection on an untrusted network.
Plasma Vault can also be used on top of full disk encryption for even more security.
Privacy is one of our core values at KDE. We don't track you, we don't collect any data about you or your behavior, we don't show you personalized ads (or ads at all), we don't throw cookies at you, and we don't sell any data to third parties.
As a general rule, software produced by the KDE Community does not transmit or otherwise transfer information from end-users devices except as a result of an explicit user action. Examples of this would include visiting webpages, sending emails, and downloading new content (such as desktop wallpapers).
Some pieces of KDE software may include telemetry components, which provide details to KDE about the device it's running on. Where this functionality exists, it is always operated on an opt-in basis and disabled by default, with the ability to change your preferences at any time and inspect the data it sends.
Synchronize your devices with KDE Connect using your local network instead of storing your data on the cloud, which consumes a lot of energy and exposes your private data to the cloud provider.
Alternatively, check out Nextcloud which lets you create your own cloud on a private personal server, ensuring that your data never leaves your custody. Many pieces of KDE software integrate with NextCloud.
Spread the word with Tokodon
Tokodon is a client for Mastodon, a social network that is not for sale and not controlled by mercurial billionaires with over-inflated egos.
