Open Grammarly ("we", "us", or "our") is committed to protecting your privacy. This Privacy Policy explains how our Chrome extension handles information.
API Keys: We do not collect or store your OpenRouter API key on our servers. The API key you provide is stored locally within your browser's secure storage (Chrome Storage API) and is only used to authenticate requests to OpenRouter.
User Text: When you use the "Correct Grammar" or "Rewrite" features, the text you have highlighted is sent to OpenRouter (https://openrouter.ai) for processing. We do not store this text on our own servers.
The information processed by the extension is used solely to provide the AI writing assistance features. We do not sell, trade, or rent your personal data or your processed text to third parties.
This extension uses OpenRouter as a third-party AI provider. Your use of the extension is also subject to OpenRouter's Terms of Service and Privacy Policy. Please review their policies to understand how they handle data sent to their models.
We use the standard Chrome Storage API to save your settings locally. We recommend keeping your API key private and not sharing it with others.
We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page.
If you have any questions about this Privacy Policy, you can contact us through our GitHub repository.
