Calendar issue


Dec 11, 2021
Hello I am having a weird calendar problem.

I have a galaxy s10+.
My dad has an iPhone 11.

Everytime I add an event on my phone calendar...the exact same event gets added to my dad's calendar. I looked at his calendar history...and every event I entered on my phone is also on his device. It copies the event name and device.

The only commonality in our phones I can think of is that we both control the same nest thermostat. I believe the next is controlled by my Google account.

I do not have an iCloud logged into any device. I have not had an iPhone in 5+ years. he does not have a Samsung or Google account logged into any device.

What the heck is going on?
Can someone help me stop this please?
Thank you.
