Encrypted by default
Your data is encrypted on your device before it ever syncs, so we cannot read it and neither can anyone else.
Independent software studio
Building privacy-first apps, carefully.
Optikal is a small studio. We build apps that keep your data encrypted and on your device, and we make them genuinely good to use. KetoCypher is our first.
No tracking, no ads
We do not run analytics that follow you around or sell your information. The app is the product, not you.
Made to be kept
Small, well tested, and maintained. Software you can rely on for years, not just a launch week.
A privacy-first keto and carnivore tracker with end-to-end encrypted cloud backup. Log meals, track macros, and watch your progress, with your health data readable only by you.
