LiquidTime is a time management app in beta. It is developed solely by Max Krieger. Little maintenence is to be expected because the app was developed to save time in the first place.
Your email is used for authentication purposes only. Google analytics is used for some insights on usage, but data is not bought or sold.
This is a time management app. Only what is necessary will be stored. However, expect some public analysis on general time spent (everything else, including identity and plan names, is anonymized).
Why can't I sign in? What's the error that popped up? Check your privacy settings, enable cookies, and try a different browser.
No Google calendar integration? It's roadmapped, but the usefulness of such is debatable. Google calendar is for one-time events, LiquidTime is for timing long-term projects. Rescheduling and syncing would be very difficult.
Can I sign in with a different account provider? Not right now.
Mobile? Not right now.
My defaults didn't save? It's necessary to hit the small purple "done" button. If you already allocated into some days, the changes will not take effect in those days until you manually adjust them.
