1. Where is the data for todist hosted?
2. I set a task on my phone with a reminder alarm for 12.30pm. No reminder occurred even though Notifications have been activated.

Reminders are a Premium only feature, and would be the reason they did not go off. You can add the date and time, but Premium will be the way to receive the reminder.
How do I set a date like:
Every three months from 20th Feb?
And a bug:
Nexus 7. Pick a date
The month selector has duplicated entries. I. E. Jan, Mar, Mar, May, May etc
The Android issue will be addressed in the next update.
Regarding the date, you can use: "every 3 months starting 20 Feb".
