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 based on visits to our site or other sites.
- Users may opt out through Google Ads Settings or www.aboutads.info.
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. We never store your full card number or CVC.
- Direct QR Payments: WeChat Pay and Alipay donations are voluntary transfers through their official clients.
4. Performance Monitoring & Server Logs
We use Vercel Speed Insights to measure real-user website performance. It collects technical performance metrics such as Core Web Vitals (including LCP, INP, and CLS), route information, and related browser, device, and network context needed to diagnose performance issues. These metrics are sent to Vercel for aggregation and performance monitoring. Vercel's processing is subject to its Privacy Policy.
Our infrastructure provider may also automatically log standard web request metadata for diagnostics and abuse prevention. We do not use Speed Insights data to create advertising profiles.
5. Changes to This Privacy Policy
We may revise this Privacy Policy periodically. Changes will be posted here with an updated effective date.
