Calendar that doesn't share personal information?
I was wondering if there's a calendar I can download for my phone that doesn't share personal information. As in, no one has access to it except me. I have the Google calendar built into my Nexus but I think it's really creepy that it connects to the Internet and if Google wants to, they can access the info and modify/add anything. As a result, I've disabled it.
I think there's a way to prevent it from syncing but it's not guaranteed Google doesn't have access to my info/plans.
All the Calendar apps I've looked up require me to give access to personal information so I don't want to download it.
I'd appreciate any suggestions, whether it's for a calendar I can download or ways to prevent access from internet by companies/people.
