PromptGrab Privacy Policy

Last updated: July 11, 2026

PromptGrab is a local-first Chrome extension for finding, copying, saving, and organizing reusable AI prompts from X/Twitter. This policy explains what the extension stores, why it uses Chrome permissions, and how your data is handled.

Single Purpose

PromptGrab's single purpose is to help users detect, copy, save, organize, and reuse AI prompts from X/Twitter pages. On other pages, users may open the sidebar to access prompts they have already saved.

Data PromptGrab Handles

When you save a detected prompt—or enable optional auto-save—PromptGrab may store the prompt text, source page URL, page title, source host, prompt type, platform hints, detection score, timestamps, and nearby preview media references such as image URLs, video poster URLs, or direct video URLs available on the source page.

PromptGrab may read page text and nearby media on supported X/Twitter pages for automatic detection. It does not scan or highlight content on non-X/Twitter pages.

Local Storage

Saved prompts are stored locally in your browser with Chrome local storage. The library page may also store a local folder handle in IndexedDB when you explicitly choose a folder for local sync. JSON exports and folder sync files are written only after you request them.

When preview images or videos are displayed, your browser may request those media files from the original source host. PromptGrab does not receive a copy of those requests or files.

Website Analytics

The public PromptGrab marketing website uses Google Analytics 4. Google Analytics helps us understand aggregate website traffic, such as page views, referrers, browser and device information, and approximate geography. This analytics tag is used on the website only and is not included in the Chrome extension package.

Extension Usage Analytics

The current Chrome extension package does not send extension usage events to Google Analytics 4. PromptGrab may add aggregate extension analytics in a future version only after updating the extension permissions and this policy.

If extension analytics is added later, it will not include prompt text, source URLs, page titles, page content, or saved media URLs.

Optional Semantic Review

Semantic review is off by default. If you enable it and provide an API key, PromptGrab may send a borderline candidate's prompt text and nearby X/Twitter context directly to the model provider you select for classification. The selected provider's own privacy terms apply to that request. PromptGrab stores provider API keys locally in Chrome and does not send them to a PromptGrab server.

Supported providers currently include DeepSeek, OpenAI, Anthropic Claude, Google Gemini, xAI Grok, OpenRouter, Mistral AI, Groq, Kimi/Moonshot, Qwen, Zhipu GLM, and SiliconFlow. PromptGrab requests access only to the provider you select.

No PromptGrab Cloud Uploads or Sales

PromptGrab does not create an account, sell user data, send saved prompts to advertising services, or upload browsing content to a PromptGrab server. PromptGrab does not allow humans to read your saved prompt library. The optional provider request described above occurs only after you enable semantic review.

Permissions

• activeTab: lets PromptGrab open the saved-prompt sidebar on the current page after you click the extension.
• scripting: injects the local detector and highlight UI into X/Twitter pages, or the saved-prompt sidebar into the current page after a user action.
• storage: saves prompts and settings locally in Chrome.
• downloads: exports your saved prompt library as a JSON file when you request it.
• x.com and twitter.com host access: enables automatic prompt detection on X/Twitter pages, where prompt sharing is a core supported workflow.
• Model provider host access: is used only when you enable semantic review, select that provider, and supply an API key. Access for providers other than DeepSeek is requested when needed.

Limited Use Disclosure

PromptGrab uses data obtained through Chrome extension permissions only to provide or improve its prompt capture and local library features. The use of information received from Google APIs will adhere to the Chrome Web Store User Data Policy, including the Limited Use requirements.

Deleting Your Data

You can delete saved prompts from the PromptGrab library. You can also remove all locally stored extension data by uninstalling the extension or clearing the extension's Chrome site data.
