Sparta

Sparta is a Sport and Rehearsal Tracking Application. It lets the user write down and save all sport activities safely and privately on the computer. No tracking and absolutely zero collection of any user data. Activities are simply saved on the computer without outside interference. Sparta uses top of line AES-256 encryption, state of the art key derivation using Argon2 and end-to-end encrypted sharing over the network using wormhole-william to keep all your data hidden from any spying eyes.

Sparta is built using the following Go packages:

• fyne (version 1.3.0 or later)
• wormhole-william (version 1.0.1 or later)
• x/crypto

Requirements

Sparta compiles into a statically linked binary with no runtime dependencies.

Downloads

Please visit the release page for downloading the latest release. Versions for Linux, MacOS and Windows are available, with an Android version possibly coming in the future.

Systems that have Go and the required prequsites for Fyne installed can alternatively install using go get:

go get github.com/Jacalz/sparta
