Hi guys

I had a small idea and was wondering if somebody had it before and if there is already an app doing this.

My problem is, that I don´t want google to "get" my data.
Appointments, Contacts and Tasks can easily be synced with googles services, but I don´t want to
give them these information.

Would it be possible to crypt parts of the data (names, numbers, descriptions, ...) before uploading to google
and decrypt it after downloading?

Thanks for your opinions and ideas.
