Most likely, one of the following things happened:
- You started your free Doodle Premium trial! Don't worry, you will not be charged. The trial will end automatically after 2 weeks.
- Your previous subscription has renewed automatically
- Your company upgraded to an enterprise account, and took you along with it! When a company buys a premium subscription they often whitelist email domains (.e.g email@example.com). All accounts using an email with that domain would be able to use Premium Doodle
