Privacy Policy

Last updated: June 30, 2026

PromptDNA helps users turn images they actively select on webpages into structured AI image prompts and related visual elements. This policy explains what data is processed, why it is processed, and how users can contact us.

Single Purpose

PromptDNA's single purpose is to help users analyze images they actively select and generate structured AI image prompts. PromptDNA does not automatically scan webpages, does not continuously monitor browsing activity, and does not analyze page content without user action.

Data Processed

• Website content, including the image selected by the user, related image source data, or a cropped visible image area when direct image access is blocked.
• A locally generated device identifier used for guest quota and abuse prevention.
• Generated prompts, extracted visual elements, local settings, and local prompt history.
• Account email, display name, provider, and authentication session data when the user signs in.
• Quota usage, check-in history, points, feature unlocks, and account administration records.
• Basic request metadata needed for security, rate limiting, diagnostics, and service operation.

When Data Is Processed

PromptDNA processes image-related website content only after the user actively triggers analysis, such as by selecting PromptDNA from the browser context menu. The extension does not collect images in the background.

How Data Is Used

• To analyze the selected image and return prompt-ready text to the user.
• To enforce guest, signed-in, and IP-based quota limits.
• To support login, check-in rewards, feature unlocks, and account administration.
• To detect misuse, debug failed requests, and operate the service reliably.

Third-Party Services

PromptDNA may use Vercel for hosting and serverless execution, Supabase for account and quota storage, and configured AI model providers for image analysis. Model provider API keys are stored on the backend and are not included in the Chrome extension frontend.

Data Sharing

PromptDNA does not sell user data and does not use user data for personalized advertising. Selected images and related prompt instructions are shared only with the configured AI provider as needed to perform the requested analysis.

Remote Code

PromptDNA does not load or execute remotely hosted code. All executable extension code is packaged with the Chrome extension. The service may call backend APIs to analyze user-selected images and return prompt results.

User Controls

• Users may use guest mode when enabled.
• Users may sign out from the extension Options page.
• Users may uninstall the extension to remove local extension storage from Chrome.
• Users may request account deletion or data export through the support contact.

Security

PromptDNA sends requests over HTTPS. Provider API keys remain in server-side deployment environment variables. Authentication tokens are stored in Chrome extension local storage.

Chrome Web Store Limited Use

PromptDNA's use of information received from Google APIs will adhere to the Chrome Web Store User Data Policy, including the Limited Use requirements.
