### What happens if my subscription payment fails?

If your subscription payment fails, there is a grace period of 15 days, including the due date. Docker retries to collect the payment 3 times using the following schedule:

- 3 days after the due date
- 5 days after the previous attempt
- 7 days after the previous attempt

Docker also sends an email notification `Action Required - Credit Card Payment Failed` with an attached unpaid invoice after each failed payment attempt. 

Once the grace period is over and the invoice is still not paid, the subscription downgrades to a free plan and all paid features are disabled.

### Does Docker offer academic pricing?

Contact the [Docker Sales Team](https://www.docker.com/company/contact).

### Do I need to do anything at the end of my subscription term?

No. All monthly and annual subscriptions are automatically renewed at the end of the term using the original form of payment.
