# Limits

We offer a free version of our app that you can use for as long as you like with some limitations placed on your usage and certain features only available on paid plans, this enables us to cover our running costs and fund future improvements. We reserve the right to change these at any time but will do our best to give you notice of any changes that might affect your usage of Check Sheet.

### Spreadsheets

You can use Check Sheet in as many spreadsheets as you like.

### Checks

You can create 1 check on our free plan, if you reach this limit you will need to either delete your existing check before you can add a new one or upgrade to one of our paid plans.

### Notifications

You can send up to 500 notifications per month on our free plan. If you wish to send more than this you will need to upgrade to a [paid subscription plan](https://checksheet.app/pricing/).

This limit will reset monthly, any remaining allowance will not rollover. You can view your remaining allowance for this month from the Check Sheet > Settings screen, accessible from the drop down menu within the Check Sheet app.

### Google

Our application is also subject to the following [quotas and limits](https://developers.google.com/apps-script/guides/services/quotas) enforced by Google. For typical usage patterns they are unlikely to affect you but they are listed here for transparency.

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://documentation.checksheet.app/limits.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
