Privacy Policy

Last updated: July 2026 · applies to PromptLens v1.1.0 and later

Summary

PromptLens collects no data. It has no backend server, no accounts, no analytics, and no telemetry. Everything it does happens in your browser and in direct requests to the AI provider you configure.

What the extension stores

Your API key — stored in chrome.storage.local on your device only. It is never synced, never sent to the developer, and never sent to any server other than the AI provider you selected.
Your preferences — chosen provider, model name, and last-used prompt dialect, stored in chrome.storage.local.
A temporary job reference — when you right-click an image, its URL is briefly held in chrome.storage.session so the result window can process it. Session storage is cleared when the browser closes.

What leaves your browser

When you generate a prompt, the selected image is converted to base64 locally and sent, along with the dialect instructions, directly to exactly one endpoint — the provider you chose in Settings:

Google Gemini — generativelanguage.googleapis.com
Anthropic Claude — api.anthropic.com
OpenAI — api.openai.com
OpenRouter — openrouter.ai

Your use of those APIs is governed by the respective provider's own privacy policy and terms. PromptLens adds no intermediary: there is no proxy, relay, or logging server in between.

What the extension does not do

No collection of browsing history, page content, or personal information
No analytics, tracking pixels, or crash reporting
No storage of generated prompts or processed images beyond the current window
No sale or transfer of any data to any party

Permissions explained

contextMenus — adds the “Generate prompt from image” right-click item.
storage — saves your key and preferences locally.
<all_urls> — required to fetch the pixels of an image you explicitly right-click on any website, so it can be sent to your chosen AI provider. The extension reads nothing else from pages and injects no content scripts.
