# Cloud service usage limits

Check below for details on the word processing limits associated with each product and subscription plan. Annual subscriptions have a word limit and this limit reflects the total word count processed by the service for all users during the entire subscription term. For free service tiers, word limits are imposed on a daily basis per website.

{% hint style="warning" %}
Clients with an Advanced (Custom) plan should [contact our sales team](https://webspellchecker.com/contact-us/) to define their unique word limit.
