AIM Calendar
Calendars and contacts that work without signing up in your browser, or those from your connected calendar accounts, all together. With recurring events, time zones and invitations from AIM Mail.

What usually happens, and how AIM Calendar solves it.
Your work and personal calendars live in different places and appointments overlap.
AIM Calendar brings them together in a single calendar, each with its own colour.
Invitations arrive by email and you end up copying them by hand.
The ones that reach AIM Mail are accepted with one click and go straight to your calendar.
Meetings with people in another country and always the doubt about what time it is.
Each event carries its time zone, and you see it in your own time.
Getting started is this simple. And this is what you'll see: screenshots of the real app.
Open AIM Calendar and create events and contacts: they are stored in your browser, no account needed.
With your free account, add your calendar and contact accounts (CalDAV and CardDAV) or subscribe to a calendar by its address.
Day, week, month or agenda, with each calendar in its own colour. Show or hide whichever you want.

What stays on your device, what travels encrypted and what we store. No small print.
What you create “On this device” is stored only in your browser: it isn't sent to our servers and we have no access to it. If you clear your browser data, it's deleted with it.
For each account we store the address, username, servers and encrypted password, plus the name and colour of each calendar. We don't store your events or contacts: we read and change them at your provider when you ask.
Each subscription's address is stored encrypted. Its content is kept in memory for five minutes at most, never on disk.
