Welcome to GPTGrammar ("we," "our," or "us"). We are committed to protecting your privacy and ensuring transparency about how we handle your data. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our web application at gptgrammar.org and our Chrome browser extension ("GPTGrammar - ChatGPT Grammar Checker").
By using our services, you agree to the collection and use of information in accordance with this policy. If you do not agree with our policies and practices, please do not use our services.
When you use GPTGrammar to check grammar, we collect the text content you submit. This includes:
Purpose: This text is sent to our servers and processed through AI language models (via OpenRouter API) to analyze grammar, spelling, punctuation, and style, and to provide you with corrections and suggestions.
We store certain preferences to enhance your user experience:
Storage: These preferences are stored locally in your browser using Chrome's local storage API and are never transmitted to our servers.
We may automatically collect certain technical information when you use our services:
Purpose: This information is used for maintaining service functionality, troubleshooting issues, and improving performance.
We use the information we collect for the following purposes:
| Data Type | Purpose | Retention |
|---|---|---|
| Submitted Text | Grammar checking via AI models | Not stored permanently |
| User Preferences | Personalized experience | Stored locally until cleared by user |
| Technical Data | Service maintenance, security | 7-30 days in server logs |
Your submitted text is sent to our server at gptgrammar.org, which then forwards it to OpenRouter's API for processing by AI language models (primarily GPT-4o-mini). The AI analyzes your text and returns grammar corrections, which we display to you.
We may use aggregated, anonymized data to improve our service quality, but we do not use your specific text content for training purposes or share it with third parties for marketing.
GPTGrammar uses OpenRouter, a third-party service that provides access to various AI language models. When you submit text for grammar checking:
OpenRouter's Privacy: OpenRouter has its own privacy policy. According to OpenRouter's practices, API requests are processed in real-time and are not used to train AI models. For more information, please review OpenRouter's Privacy Policy.
We do not sell, rent, or share your personal information or submitted text content with any other third parties for marketing or advertising purposes.
We may disclose your information if required to do so by law or in response to valid requests by public authorities (e.g., court orders, subpoenas).
We take the security of your data seriously and implement appropriate technical and organizational measures:
However, no method of transmission over the internet or electronic storage is 100% secure. While we strive to protect your information, we cannot guarantee absolute security.
Retention Period: We do not permanently store the text you submit for grammar checking. Your text is processed in real-time and discarded immediately after the grammar check results are returned to you.
Retention Period: Technical logs (IP addresses, timestamps, error messages) may be retained for 7-30 days for troubleshooting and security purposes, after which they are automatically deleted.
