Promptlee is a client-side prompt analysis tool. All analysis runs locally in your browser. We do not collect, store, or transmit your prompts or personal data to any server.
Data Collection
What Promptlee does NOT collect:
Your prompts or AI chat messages
Personal information (name, email, account details)
Browsing history beyond supported AI sites
Cookies or tracking identifiers
Keystrokes or form data
What Promptlee stores locally:
Analysis history (score, token count, grade, cost/energy estimates, site name, timestamp) — stored in Chrome's local storage on your device only. You can disable history in Settings or clear it at any time.
User preferences (theme, enabled sites, model tier, score threshold) — stored in Chrome sync storage so your settings follow your Chrome profile.
Anonymous analytics ping:
Promptlee sends a minimal, anonymous ping on extension install and when an analysis is performed. This ping contains only the event type (e.g., "install" or "analyze") and the extension version number. No prompt content, scores, personal data, or identifiable information is included. The ping uses a fire-and-forget GET request with no cookies. You can verify this in the open-source background.js file.
Data Sharing
Promptlee does not share any data with third parties. There are no advertising SDKs, analytics frameworks, or data brokers integrated into the extension.
Data Storage
All analysis data is stored in your browser's local storage (chrome.storage.local) and never leaves your device. Settings are stored in Chrome sync storage (chrome.storage.sync) to follow your Chrome profile across devices — this is a built-in Chrome feature and does not involve any third-party servers.

Promptlee requests the following Chrome permissions:
activeTab: To read the prompt text from the currently active AI chat tab when you click Analyze.
storage: To save your settings and analysis history locally.
contextMenus: To add the "Analyze with Promptlee" right-click option.
Host permissions (claude.ai, chatgpt.com, gemini.google.com, perplexity.ai, poe.com): To inject the Promptlee sidebar and floating badge on supported AI sites.
User Controls
