# Billing

{% hint style="info" %}
Biodock uses Stripe to collect your payment information.  We never store, process, or even see your sensitive payment information.

### Billing and Payments

#### Adding a Payment Method

To add a payment method:

1. Navigate to **Settings → Billing**.
2. Click **Add Billing Method**.
3. You will be redirected to **Stripe**, where you can securely add a credit card or another supported payment method.

Adding a payment method allows you to purchase additional Run Credits and Storage when needed. Your payment method will only be charged when you complete a purchase.

#### Purchasing Additional Credits and Storage

Academic users can purchase additional **Run Credits** and **Storage** at any time from the **Billing** page in their account settings.

**Run Credits**

Run Credits are available through two purchase options:

* **Annual Subscription** – Renews automatically each year and offers a lower cost per credit.
* **One-Time Purchase** – A single, non-recurring purchase.

**Storage**

Additional Storage is available through an **Annual Subscription**, which renews automatically each year.

#### Subscription Renewals and Cancellations

Subscription plans renew automatically at the end of each billing period. If you do not wish to renew your subscription, please cancel it before the renewal date.

> <sub>Refunds are not available for subscription purchases.</sub>

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.biodock.ai/user/billing.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
