💾 Client-Side LocalStorage Sandboxing (Optional)
If you explicitly toggle the "Remember address(es)" checkbox, the input string is saved entirely inside your device's native browser storage partition (localStorage). This text payload is physically locked inside your sandbox profile; it is never transmitted to any remote tracking array, network server, or external system. Unchecking the option immediately purges it permanently from local device memory.
🚫 No Tracking, Cookies, or Pixels
This software operates with absolutely zero analytical monitoring packages, tracking scripts, tracking cookies, or tracking tags.
🚫 Zero Third-Party CDN Dependencies (Zero-Script Leaks)
Unlike standard software, this platform does not request remote scripts or libraries (such as Chart.js) from Content Delivery Networks (CDNs). There are no external JavaScript calls. This eliminates third-party caching fingerprinting and script manipulation vulnerabilities.
🚫 No Backend Infrastructure or Database
There is no backend server or database connected to this webpage. Because data-retention hardware is physically non-existent, your public wallet balances can never be intercepted, logged, or saved.
🌐 Direct Blockchain Inquiries
When you execute tracking, your browser makes targeted read-only calls directly to the open-source API endpoint configured in your options menu (defaulting to mempool.space). No middleman proxy coordinates or intercepts the data transfer. BitcoinDaysCreated.com never sees what address(es) you are tracking.
📦 Fully Auditable Native Engine
All graphical timeline representations and accumulation calculations are drawn dynamically via native client-side HTML5 Canvas code built directly into the file. We also make this page downloadable from our GitHub repository with a link at the bottom of the page so it can be ran locally without ever needing to touch BitcoinDaysCreated.com.
Don't Trust, Verify: Right-click this viewport and choose "View Page Source". You will see clean, readable, self-contained JavaScript running entirely inside your local browser instance.
