PulseX — Privacy Policy

Last Updated: October 17, 2026 • Manifest V3 Compliant

Zero-Data Architecture

Zero-Data Philosophy: PulseX is built with a Bring-Your-Own-Key (BYOK) architecture. We do not operate external servers, databases, or analytics tracking. Your API key and preferences remain 100% locally on your computer.

1. Data Collection & Processing

PulseX collects no personal data. Specifically:

No Identity Tracking: We do not ask for or collect names, email addresses, usernames, or IP logs.
No Keystroke Logging: We do not record or monitor browser activity outside the explicitly triggered reply assistant functions on supported pages.
No Analytics or Telemetry: We do not use Google Analytics, Mixpanel, Sentry, or any background tracking scripts.

2. DeepSeek API Key Security

PulseX requires a user-provided DeepSeek API key to generate completions:

Your key is encrypted in Chrome's sandboxed local storage (chrome.storage.local).
Requests are dispatched directly from your browser to DeepSeek's official endpoint (https://api.deepseek.com).
Your key is never routed through, inspected by, or stored on any intermediary server.

3. Chrome Permissions & Justification

Permission	Usage & Justification
`storage`	Persists your chosen AI provider (DeepSeek, OpenAI, Claude, Gemini, Groq, OpenRouter, or Local), model, persona presets, and API keys locally on your device.
`https://x.com/` `https://twitter.com/`	Extracts context of the specific tweet you choose to reply to and inputs your selected draft directly into the reply composer.
`https://api.deepseek.com/` `https://api.openai.com/` `https://api.anthropic.com/` `https://generativelanguage.googleapis.com/` `https://api.groq.com/` `https://openrouter.ai/` `http://localhost/*`	Sends user-initiated completion requests directly to your selected AI provider's official API. Zero proxy servers.

4. Third-Party Services

Prompt payloads (containing the tweet context and your chosen reply angle) are transmitted directly to Hangzhou DeepSeek Artificial Intelligence Co., Ltd. Processing is subject to DeepSeek's API terms and privacy guidelines.

5. How to Delete Your Data

Since data is stored purely locally on your device:

Clear your settings in the extension popup at any time.
Uninstalling the extension instantly purges all associated local storage data from your Chrome profile.
