Grammarly’s algorithms analyze the text you write, information on how you write, usage data, and other information you intentionally enter or automatically submit to our systems in order to provide you with writing suggestions, insights, and product usage tips.

Grammarly takes extreme care to isolate each customer’s data. Any writing that an individual or organization reviews or produces with Grammarly will never appear in another customer’s writing suggestions.

Any information used to power Grammarly’s generative AI features, such as prompt type, prompt text, and the context in which it’s used, will be shared with our small number of thoroughly vetted partners for the sole purpose of providing you with the Grammarly experience. We do not allow any partners or third parties to use your data for training their models or improving their products.

You may opt out of allowing Grammarly to use your content to improve its products or train its models. We do not train on any content from certain business users or users whose accounts originate in the EU or UK, automatically.
