Local-First Web App Release Pack

This practical, engine-neutral pack turns the lessons behind SnackPDF into a repeatable release system for developers and reviewers. It covers data-lifetime mapping, browser network and storage testing, genuine cancellation, memory preflight, atomic offline updates, mobile saving, keyboard flows and cross-browser evidence.

You receive:

• a concise 12-page implementation and release handbook

• five printable release gates

• editable data-lifetime, technical-audit and error-message templates

• a formula-driven browser test matrix with 43 gates

• an original Playwright privacy test harness

• safe and deliberately leaky self-test apps

Built for browser applications that process files, images, documents or other sensitive data locally. The pack is independent of any PDF engine.

This is engineering guidance, not legal advice, certification or a generic privacy-policy template. SnackPDF itself is not included.

Delivery: one versioned ZIP. A single purchaser may adapt the templates for their own projects and direct client work; the original pack may not be redistributed. Updates are discretionary and are not a subscription promise.
