This is cool. Working on something similar. I was wondering, are the tasks/notes/calendars/contacts all in your own system? Or can they be bridged using open protocols like CalDAV/CardDAV/iCal? My current approach for building something like this is to build only the processing/dashboard side, and keep using Todoist for storing tasks, Google Calendar for calendars etc, and then piece by piece migrate to fully self-hosted solutions like Owncloud/Nextcloud that provide standard protocol based storage. The main reason for my approach is that I do not want to implement Todo/Calendar/etc from scratch with UI's for every platform. Todoist works fine (and other open source CalDAV apps too), same with Google Calendar, so I want to get up and running using those apps on my phone, but still track the combined data in my own system.
