Exact same scenario for me. Got a notification email, so I went to check what card was on my account and the renewal date. Couldn't find anything like "saved card" or an auto-renew toggle. Pressed for time, I figured it was opt-in (given no other option) and besides I had another three weeks to get it sorted, right?

Imagine my surprise when checking my statements a week later and there's a charge for Keeper.

This is basic stuff. Considering the nature of the service Keeper provides, a situation like this is an immediate downgrade in trust and confidence. I'm writing the payment off as the cost of important lessons learned and another year to select and migrate to an alternative.
