<!-- 1. OVERVIEW -->
<div class="section">
<span class="section-anchor" id="overview"></span>
<h2><span class="icon">🔍</span> 1. Overview</h2>
<div class="highlight">
<p><strong>NODUS is a local-first browser extension.</strong> Everything you capture — ideas, notes, highlights, tags, chains, and projects — is stored exclusively in your browser's local storage (<code>chrome.storage.local</code>) and never uploaded to any server.</p>
</div>
<p>NODUS makes two types of external connections, both clearly described in this document:</p>
<div class="card">
<div class="card-title"><span class="badge badge-yellow">opt-in</span> Anonymous telemetry</div>
<p>Disabled by default. If you choose to enable it, only aggregated usage statistics are sent — never your content.</p>
</div>
<div class="card">
<div class="card-title"><span class="badge badge-blue">PRO only</span> License validation</div>
<p>Only for paid PRO subscribers. Sends a hashed device fingerprint and your email to verify the license. No conversation content is ever included.</p>
</div>
</div>
<!-- 2. LOCAL DATA -->
<div class="section">
<span class="section-anchor" id="local-data"></span>
<h2><span class="icon">💾</span> 2. Data stored locally on your device</h2>
<p>All of the following is stored in <code>chrome.storage.local</code> — meaning it lives only on your computer and is never sent anywhere unless you explicitly export it.</p>
<ul class="check">
<li>Captured ideas, notes, and highlights</li>
<li>Tags and queue assignments</li>
<li>Chains and chain templates</li>
<li>Projects and project metadata</li>
<li>Dashboard layout preferences</li>
<li>Language and animation settings</li>
<li>Telemetry event queue (if opted in)</li>
<li>Anonymous ID — a locally-generated SHA-256 hash with a random salt, never linked to your identity</li>
</ul>
<div class="highlight highlight-yellow">
<p>NODUS does not have a user account system. There is no cloud sync, no server-side profile, and no way for us to identify you from the data stored locally.</p>
</div>
</div>
<!-- 3. ENDPOINTS -->
<div class="section">
<span class="section-anchor" id="endpoints"></span>
<h2><span class="icon">🌐</span> 3. External endpoints explained</h2>
<p>NODUS connects to external URLs in three scenarios: telemetry (opt-in), license validation (PRO only), and reading files you have already uploaded to AI platforms. Here is every endpoint used and exactly what is sent.</p>
<h3>3a. NODUS infrastructure</h3>
<div class="endpoint-block">
<div class="endpoint-header">
<span class="endpoint-url">https://nodus-worker.mmcarvalho-dev.workers.dev/telemetry/batch</span>
<span class="badge badge-green">opt-in only</span>
</div>
<div class="endpoint-body">
<p>Receives anonymous aggregated usage statistics. Only called if you have enabled telemetry in Settings. See <a href="#telemetry" style="color:#60a5fa;">Section 4</a> for full details.</p>
<p class="data-sent"><strong>Data sent:</strong> anonymous ID (SHA-256 hash) · event type counts · platform counts · no conversation content · no URLs · no text</p>
</div>
</div>
<div class="endpoint-block">
<div class="endpoint-header">
<span class="endpoint-url">https://nodus-worker.mmcarvalho-dev.workers.dev/auth/status</span>
<span class="badge badge-blue">PRO only</span>
</div>
<div class="endpoint-body">
<p>Validates your PRO license on startup. Only called if you have entered a license token. See <a href="#license" style="color:#60a5fa;">Section 5</a> for full details.</p>
<p class="data-sent"><strong>Data sent:</strong> email address · hashed device fingerprint · no conversation content</p>
</div>
</div>
<h3>3b. AI platform file access</h3>
<p>These endpoints are accessed <strong>read-only</strong> when you trigger Full Chat Capture or file attachment features. NODUS reads the file content to display or save it locally. Nothing is uploaded to NODUS servers.</p>
<div class="endpoint-block">
<div class="endpoint-header">
<span class="endpoint-url">https://files.oaiusercontent.com/* · https://*.oaiusercontent.com/* · https://cdn.openai.com/*</span>
<span class="badge badge-gray">read-only</span>
</div>
<div class="endpoint-body">
<p>User-uploaded files and images in ChatGPT conversations (images, PDFs, attachments). NODUS reads these files locally to include them in Full Chat Capture.</p>
</div>
</div>
<div class="endpoint-block">
<div class="endpoint-header">
<span class="endpoint-url">https://*.anthropic.com/*</span>
<span class="badge badge-gray">read-only</span>

<!-- 4. TELEMETRY -->
<div class="section">
<span class="section-anchor" id="telemetry"></span>
<h2><span class="icon">📊</span> 4. Optional anonymous telemetry</h2>
<div class="highlight highlight-yellow">
<p><strong>Telemetry is disabled by default.</strong> You must explicitly enable it in Settings → Telemetry to activate it. You can disable it at any time and all locally queued data is cleared immediately.</p>
</div>
<h3>What telemetry collects (when enabled)</h3>
<ul class="check">
<li>Event type counts (e.g. "3 saves, 1 inject") — no content, no text</li>
<li>Platform counts (e.g. "used on ChatGPT 2 times") — no URLs</li>
<li>Anonymous ID — a locally-generated SHA-256 hash, not linked to your identity</li>
<li>Aggregated session counts per day (temporal binning)</li>
</ul>
<h3>What telemetry never collects</h3>
<ul class="check cross">
<li>Conversation content, prompts, or AI responses</li>
<li>URLs visited or page titles</li>
<li>Your name, email, or any identifying information</li>
<li>IP address (not stored by our worker)</li>
<li>Device specifications or browser fingerprint</li>
</ul>
<h3>How data is processed before sending</h3>
<p>Events are aggregated locally before transmission. Instead of sending raw events, NODUS sends aggregated counters (e.g. how many saves happened, by which platform) with privacy-preserving noise applied (±2 random offset per counter). Raw events never leave your device.</p>
<h3>Data retention</h3>
<p>Aggregated telemetry data is retained on our servers for a maximum of 12 months, after which it is deleted. Local event logs are retained for 90 days in your browser storage, then automatically cleaned up.</p>
</div>
<!-- 5. LICENSE -->
<div class="section">
<span class="section-anchor" id="license"></span>
<h2><span class="icon">🔑</span> 5. PRO license validation</h2>
<p>If you purchase NODUS PRO, the extension validates your license with our server on startup. This is the minimum required to verify a paid subscription.</p>
<h3>What is sent during license validation</h3>
<ul class="check">
<li>Your email address (as entered when activating)</li>
<li>A hashed device fingerprint (browser-generated identifier, not your hardware serial)</li>
</ul>
<h3>What is never sent</h3>
<ul class="check cross">
<li>Conversation content or anything you have captured</li>
<li>Your IP address (not stored, only used for routing by Cloudflare)</li>
<li>Any telemetry data (these are separate systems)</li>
</ul>
<p>License data is stored in a Cloudflare D1 database (Brazil/South America region). It is used solely to validate whether your subscription is active. It is never sold or shared with third parties.</p>
<p>The FREE version of NODUS works entirely offline and never contacts our license server.</p>
</div>
<!-- 6. FILE ACCESS -->
<div class="section">
<span class="section-anchor" id="file-access"></span>
<h2><span class="icon">📎</span> 6. File access on AI platforms</h2>
<p>When you use Full Chat Capture or the file attachment features, NODUS may fetch files that you have already uploaded to an AI platform (ChatGPT, Claude, Gemini, Copilot) in order to include them in your local capture.</p>
<div class="highlight">
<p><strong>This access is read-only and local.</strong> NODUS reads the file content directly from the AI platform's CDN into your browser's memory and saves it to your local storage (<code>chrome.storage.local</code>). The file is never re-uploaded to any NODUS server.</p>
</div>
<p>The browser permissions required for this (<code>*.oaiusercontent.com</code>, <code>*.anthropic.com</code>, <code>storage.googleapis.com</code>, <code>*.blob.core.windows.net</code>) allow NODUS to read those files. They do not allow NODUS to write to, modify, or transmit your data on those platforms.</p>
</div>
<!-- 7. NEVER -->
<div class="section">
<span class="section-anchor" id="never"></span>
<h2><span class="icon">🚫</span> 7. What we never do</h2>
<ul class="check cross">
<li>Sell your data to any third party</li>
<li>Read, store, or transmit your conversation content</li>
<li>Track which websites you visit outside AI platforms</li>
<li>Use advertising SDKs or third-party analytics</li>
<li>Inject ads or affiliate links into AI platforms</li>
<li>Access your microphone, camera, or clipboard without action</li>
<li>Sync your captured data to any cloud without your explicit export</li>
</ul>
</div>
<!-- 8. RIGHTS -->
<div class="section">
<span class="section-anchor" id="rights"></span>
<h2><span class="icon">⚖️</span> 8. Your rights (LGPD / GDPR)</h2>
<p>NODUS is compliant with the Brazilian Lei Geral de Proteção de Dados (LGPD) and the EU General Data Protection Regulation (GDPR), and compatible with CCPA.</p>
<h3>Rights you have</h3>
<ul class="check">
<li><strong>Access</strong> — All data stored locally is visible and exportable from the NODUS dashboard at any time</li>
<li><strong>Deletion</strong> — You can delete all local data from Settings → Clear All Data. Uninstalling the extension also removes all local data</li>
<li><strong>Portability</strong> — Export all your ideas as JSON, Markdown, or DOCX at any time</li>
<li><strong>Opt-out</strong> — Disable telemetry at any time in Settings → Telemetry</li>
<li><strong>License data deletion</strong> — Contact us to request deletion of your email from our license database</li>
</ul>
<h3>Legal basis for processing</h3>
<p>Telemetry is processed under <strong>consent</strong> (opt-in). License validation is processed under <strong>contract performance</strong> (verifying a paid subscription). No other processing occurs.</p>
