Welcome to Deep JS (“we”, “us”, or “our”, accessible via deepjs.dev). We respect your privacy and are committed to protecting your personal data. This Privacy Policy explains how your information is collected, used, and safeguarded.
1. Information We Collect and How We Use It
Deep JS is an interactive educational tool. We do not require user account registration, nor do we collect passwords or sensitive identity profiles during standard browsing.
- Code Inputs: JavaScript snippets typed into the interactive editor are parsed and simulated locally and transiently for animation rendering.
- Local Storage Preferences: We store non-identifiable UI preferences (such as selected language and dark/light theme mode) exclusively in your browser's localStorage.
2. Cookies and Third-Party Advertising (Google AdSense)
To support free access and hosting costs, Deep JS partners with third-party advertising networks, including Google AdSense.
- Third-party vendors, including Google, use Cookies to serve ads based on a user's prior visits to this website or other websites on the internet.
- Google's use of advertising cookies enables it and its partners to serve ads to users based on their visits to our site and/or other sites on the internet.
- Users may opt out of personalized advertising by visiting Google Ads Settings, or by visiting www.aboutads.info to opt out of a third-party vendor's use of cookies for personalized advertising.
3. Voluntary Sponsorship & Payment Gateways
If you choose to support the developer via our voluntary sponsorship modal:
- Stripe: Credit Card, Apple Pay, and Google Pay transactions are processed directly by Stripe, Inc. We never store, capture, or have access to your full credit card number or CVC security codes.
- Direct QR Payments: WeChat Pay and Alipay donations are peer-to-peer voluntary transfers processed by their respective official payment clients.
4. Web Analytics & Server Logs
Our infrastructure provider (Vercel / Cloudflare) automatically logs standard web request metadata (e.g., IP address, browser user-agent, referrers, request timestamps) purely for operational diagnostics, rate limiting against abuse, and performance monitoring.
5. Changes to This Privacy Policy
We may revise this Privacy Policy periodically to reflect technological or regulatory updates. Any changes will be posted directly to this page with an updated effective date.
