Don't let your energy drift away from where it's needed most. Ddidoc doesn't distract you with flashy achievements or addictive UI patterns designed just to grab your attention.

Even if you change devices or reinstall the app, your traces of immersion are safely stored in the cloud and can be retrieved at any time. • Privacy First Ddidoc never sends your focus data to external servers, nor do we share or commercialize it with third parties.
