Calensync - Google, Outlook, and iCalendar syncing solution

Calensync is a simple solution that allows you to synchronize multiple calendars together with a lot of customization available. For example, you can sync your personal events to your professional calendar, but replacing the title to maintain your privacy. On top of that, you can also create shareable event booking pages that are synced with your calendars, to make booking as simple as possible. The reason I built it was, as a freelancer, I've had to deal with more than 3 calendars at the same time during some periods, with people creating events and inviting me, obviously leading to conflicts. I wasn't happy with the existing solutions, which is why I decided to create my own.
