## Overview

Calendar0 allows you to start for free with a set number of assistant chats before requiring a plan. When you are ready for unlimited access, advanced assistant features, and call recordings, you can upgrade to a paid plan. You can review your usage limits, select a subscription or lifetime license, manage your payment methods, and access the secure customer billing portal at any time from your settings.

## Reviewing Usage Limits

Free accounts include a limited number of assistant chat messages. Once you approach or reach this limit, you will see usage meters and prompts in the application.

- **Free Chats Meter:** Visible on your billing settings page, this meter shows how many free chats you have used and how many remain.
- **Usage Walls:** If you exhaust your free chats while interacting with the assistant, a prompt will appear letting you know that it is time to upgrade to continue.

## Upgrading to Pro

### How to Upgrade Your Plan
1. Open your application settings and navigate to the **Billing** section (or click **Upgrade** from any usage limit prompt).
2. Review the available paid tiers, which include recurring options and lifetime access.
3. Click the **Upgrade** button on the plan card of your choice.
4. Complete your purchase through the secure checkout window. 
5. Once your payment goes through, the app will briefly display a setup status while your new plan is activated.

> [!NOTE]
> When returning from a successful checkout, the system automatically waits for confirmation and updates your plan status within a few moments. If it takes slightly longer, you can use the **Refresh** button to check for updates manually.

## Managing Payment Methods and Subscription Settings

### How to Access the Billing Portal
1. Go to your application **Settings** and select **Billing**.
2. Click the **Manage subscription** button next to your active plan details.
3. This will open the secure customer billing portal in a new view, where you can safely manage your payment methods and download past invoices.

> [!WARNING]
> If a recurring payment fails, your access may be temporarily paused until you update your payment method. An alert notice will appear in your billing settings with instructions to restore your access via the billing portal.
