Privacy Policy

Last updated: July 7, 2026

Welcome to Carbon Note (https://www.carbonnote.app/). This Privacy Policy explains how we handle your information when you use our website and web application.

1. Local-First Architecture & Document Privacy

Carbon Note operates entirely within your local web browser. To guarantee maximum privacy:

• Zero Server Uploads: All your compiled notes, custom written text, LaTeX mathematical equations, and Mermaid source codes are processed and rendered entirely client-side. We do not transmit, analyze, or store your documents on any external cloud databases or backend servers.
• Browser Sandbox Partition: Your documents are saved securely inside your browser's isolated HTML5 LocalStorage sandbox. Your data remains strictly local and under your own control.
• No User Account System: We do not require registrations, profile sign-ups, or login sessions. We do not gather or maintain personal identity credentials.

2. Google AdSense & Third-Party Cookies

To support the free operational maintenance of this minimalist utility, Carbon Note displays advertisements provided by Google AdSense. In compliance with advertising policies, please take note of the following declarations:

• Third-Party Vendors: Third-party vendors, including Google, use cookies to serve ads based on your prior visits to Carbon Note or other websites on the Internet.
• Advertising Cookies: Google's use of advertising cookies enables it and its partners to serve targeted ads to you based on your visit to our site and/or other websites across the web.
• Personalized Advertising Control: You can choose to opt out of personalized advertising at any time by visiting Google Ads Settings. Alternatively, you can opt out of a third-party vendor's use of cookies for personalized advertising by visiting the About Ads Portal.

3. Privacy-First Analytics

We may integrate lightweight, privacy-focused client telemetry (such as Vercel Analytics) to track general, anonymized metrics (like overall visit volumes, aggregate device ratios, and system load speeds). These modules do not collect, intercept, or track individual files, document contents, or sensitive personal data.

4. Policy Revisions

We reserve the right to modify this Privacy Policy at any time. Any changes will be published directly on this page to ensure transparency.

5. Contact & Inquiries
