App for daily gratitude journal that is privacy friendly

I've been using the following app as a daily gratitude journal but it occurred to me that the app could be selling a heap of personal info to 3rd parties.

Has anyone checked out the privacy policy or know a tool to make the check quicker?

Assuming the privacy policy isn't great, could anyone suggest a privacy friendly alternative?
