The Zero-Logs Data Lifecycle

1. Static Asset Load: Your browser fetches static HTML, CSS, and JS bundles from edge CDN caches. Once loaded, no further server connection is necessary.
2. In-Memory Execution: When you input numbers or drop an image, your device's CPU/RAM executes the mathematical calculations or canvas rendering locally.
3. Direct Blob Download: Output files (such as PDFs, PNGs, and HTML strings) are generated as in-memory binary Blobs (`blob:http://...`) and downloaded directly to your drive.
4. Volatile Memory Evaporation: When the browser tab is closed or refreshed, the transient RAM addresses are reclaimed by your operating system. Zero residuals remain.
Legal Statement on Data Breach Immunity

Because ZeroTool.online transmits and archives zero user data on remote web servers or databases, a centralized server-side data breach is technically, architecturally, and legally impossible. ZeroTool.online bears zero custodial liability for local malware, screen scrapers, or spyware residing on the user's personal hardware. Users maintain sole legal custody over their local machine environment.
