Developer Suite FAQ

Are my files really not uploaded to any server?

Absolutely. Kreotar uses local browser-based execution. Your files are processed in your RAM and are never transmitted to our servers, ensuring 100% data sovereignty.

Is there a limit on file size?

Since processing happens locally, there are no artificial server-side limits. Your only constraint is your device's memory and processor speed.
