"Why do you collect Credit Card information?"
We collect card information for the free plan in order to handle abuse. The free plan is available for use for up to five users / team storing up to 5 GB of data total within the team. If a user's team exceeds those bounds, we will move them to a paid tier of service. Should the user return to compliance within a reasonable timeframe we are happy to refund any charges that may have occurred.
"Why does the free plan say it's a trial and charge me 1¢?"
This is a limitation of our billing system. Technically the free plan is a 5 year trial costing one cent after the trial ends. We are looking into ways to improve that flow but in the meantime if after five years you are charged a penny and would like a refund, we can furnish that for you at that time.
