Preview Of Calendar0:
Some important questions you might have…
Will IT freak out about this?
No. Calendar0 is a desktop app, not a browser extension. It uses standard Google OAuth (the same secure login you use everywhere). Your calendar stays in Google’s servers. Calendar0 just displays it better. IT actually prefers this to sketchy browser plugins.
Does this work with my work calendar?
Yes. Calendar0 works with Google Workspace (your company Gmail) and personal Google accounts. See all your calendars in one view without switching accounts.
Will people know I’m using this?
No. When you schedule meetings, they just get a normal Google Calendar invite. Nobody knows you typed ‘lunch with sarah tomorrow’ and let AI do the rest. It looks exactly like you did it the old way.
What exactly can I type?
Anything you’d say out loud: ‘Am I free at 2 pm?’ ‘move my 1:1 to next week’ ‘schedule standup with engineering Monday 10 am’ ‘find 2 hours for deep work’. Just type what you’re thinking.
What if it screws up and schedules something wrong?
CalendarO shows you what it’s about to do before sending invites. You confirm or cancel. Plus, it’s just creating normal Google Calendar events you can edit anytime. Same as if you made a mistake yourself.
Is this deal exclusive to new users?
No, this deal is available for both new and existing users of Calendar0.
Is this actually secure?
Yes. We use the same security as Google Calendar itself – OAuth2, encrypted connections, no password storage. Your tokens are encrypted on your device using your operating system’s secure storage. We can’t see your calendar data even if we wanted to.
