Overview
This policy explains in detail what data the extension handles locally in your browser and how it interacts with third-party AI services.
Information the Extension Handles
| Data | Where it lives | Who can access it |
|---|---|---|
| API Keys Anthropic, OpenAI, or Google |
chrome.storage.syncSynced across your Chrome sign-in |
Only you and the AI provider you send requests to. Never us. |
| Analysis History Up to 50 recent prompts |
chrome.storage.localOn your device only |
Only you. Stays on-device. You can clear it at any time. |
| Selected App Preference Your chosen "Copy & Open in" app |
chrome.storage.localOn your device only |
Only you. |
| Image Data Images you choose to analyse |
Not stored anywhere | Fetched, base64-encoded, sent directly to your chosen AI provider, then discarded. We never receive or store image data. |
How Your Data Is Used
- API keys are used exclusively to authenticate requests to the AI provider you select. They are read from local storage, attached to the API request header, and never logged or forwarded elsewhere.
- Images are fetched directly in your browser, converted to base64, and sent in a single API request to the AI provider. The response (the generated prompt) is displayed to you and saved to local history. Neither the image nor the prompt is sent to us.
- History is stored locally so you can review past results. It is never uploaded.
What We Do Not Do
- We do not operate any server or backend.
- We do not collect analytics, crash reports, or usage statistics.
- We do not use cookies or tracking technologies.
- We do not sell, share, or monetise any data.
- We do not have access to your API keys or browsing activity.
Third-Party AI Services
When you analyse an image, the extension sends a request directly from your browser to the AI provider you have configured. Each provider has its own privacy policy governing how they handle data:
We encourage you to review those policies. Image to Prompt does not control how these providers handle data once it reaches their APIs.
Chrome Permissions Explained
| Permission | Why it's needed |
|---|---|
storage |
To save your API keys, analysis history, and app preference locally in Chrome. |
activeTab |
To open the side panel on the current tab when analysis completes. |
contextMenus |
To add the "Convert to AI Prompt" right-click menu item on images. |
sidePanel |
To display the results panel alongside the page. |
<all_urls> host permission |
To detect images on any webpage you visit and fetch their pixel data for analysis. The extension only acts when you explicitly click the Retrieve Prompt button or right-click an image. |
Your Control Over Your Data
Because all data is stored locally in your browser, you have full control:
- Delete history — click "Clear history" in the side panel at any time.
- Remove API keys — go to the extension Settings page and clear the key fields.
- Remove all data — uninstalling the extension deletes all locally stored data automatically.
Children's Privacy
This extension is not directed at children under 13. We do not knowingly collect any personal information from children.
Changes to This Policy
If we make material changes to this privacy policy, we will update the "Last updated" date at the top of this page and note the change in the extension's GitHub repository. Continued use of the extension after changes are posted constitutes acceptance of the updated policy.
