DemNova (“we”, “us”, or “our”) is committed to protecting your privacy while providing a powerful Chrome extension that leverages GPT-4 Vision technology to analyze web content and deliver quick, context-aware answers. This Privacy Policy explains how we collect, use, store, and safeguard your information when you use the DemNova Chrome Extension (“Extension”). By installing and using our Extension, you agree to the terms described herein.
Login Credentials & Subscription Data: When you log in via the extension’s popup, we collect your email and password to authenticate your identity. We then retrieve and store your subscription status from our backend service for a personalized experience.
User Preferences and Settings: The Extension allows you to configure settings such as your OpenAI API key, model selection (e.g., GPT-4, GPT-4 Vision), auto-answer enablement, and invisible text selection preferences. These settings are stored locally using your browser’s storage.
User-Generated Content: When you interact with the Extension (e.g., by selecting text, pasting images, or initiating a chat), the content you provide—including text selections, screenshots, or images—is used solely to generate context-aware answers and visual analysis using our GPT-4 Vision integration.
Captured Web Content: With your permission, the Extension can capture the visible content of web pages or specific screenshots to analyze images and text. This data is transmitted securely to our servers (and/or OpenAI’s API) for processing and is not stored permanently unless required to improve your user experience.
Browser and Device Information: For performance and troubleshooting purposes, the Extension may collect non-identifiable technical data, such as browser type, device model, and usage patterns. This information is used solely for the improvement of our services.
Providing Core Functionality: The collected data (user input, screenshots, and settings) is processed to enable our key features, including real-time analysis of web content, generation of direct answers via GPT-4 Vision, and an enhanced browsing experience through invisible text selection.
Personalization and Performance: Your settings and preferences are stored locally to ensure that your experience remains consistent across sessions. Anonymous technical data may also be analyzed to improve the performance, security, and functionality of our Extension.
Secure API Communication: When generating answers or analyzing images, the Extension communicates with our backend services (hosted at https://demnova.com) and OpenAI’s API (https://api.openai.com). These communications are secured and include a unique extension token to ensure proper authentication.
Local Storage: User settings, preferences, and conversation history are stored locally via your browser’s storage (chrome.storage.sync and chrome.storage.local). This data remains on your device unless you choose to clear it.
Transient Data for Processing: Content captured for analysis (e.g., screenshots and selected text) is transmitted to our servers for immediate processing. We do not store this data long-term unless necessary for service improvement or as required by law.
Data Retention Period: Personal data (e.g., login credentials and subscription details) is retained only as long as needed to provide the service. You may request deletion of your data at any time by contacting us using the details provided below.
Third-Party Service Providers: We share your data only with trusted third-party service providers (such as OpenAI for AI processing) strictly to deliver our service. These providers are contractually obligated to protect your data.
Legal Requirements: We may disclose your information if required by law or in response to valid requests by public authorities, such as a court order or government regulation.
No Sale of Personal Data: We do not sell, trade, or rent your personal information to third parties for their marketing purposes.
We implement industry-standard security measures to protect your data during transmission and storage. Although no method of online transmission is completely secure, we take every precaution to ensure your information is protected. Please note that you also play a role in maintaining security by safeguarding your credentials and device.
Opting Out: You can disable features such as auto-answer or invisible text selection through the Extension settings if you prefer not to capture or process certain types of data.
Data Access and Deletion: You may request access to the data stored by the Extension or ask for its deletion by contacting us at the Support Email below. Local data stored in your browser can be cleared via your browser’s settings.
The Extension may include links to third-party websites or services. Our Privacy Policy does not extend to these external sites, and we encourage you to review their privacy policies before providing any personal information.
We may update this Privacy Policy from time to time to reflect changes in our practices or legal requirements. We will notify you of significant changes by posting the updated policy on our website at https://demnova.com/privacy-policy and, where appropriate, within the Extension.
