About STILLFANTASY
Building high-performance, privacy-first, zero-server-leakage utility software for global creators, engineers, and financial planners.
1. Our Core Philosophy: Zero-Knowledge Client Sandboxing
Founded in 2026, STILLFANTASY was established in response to widespread data harvesting across online developer utilities. Too many existing tools upload confidential JSON data, proprietary database dumps, authentication JWTs, and financial details to uncontrolled third-party servers.
We operate on a strict 100% Client-Side Architecture. Whether you are validating a JSON schema, calculating a 30-year PITI mortgage amortization schedule, generating a secure 64-character password with high Shannon entropy, or compressing multi-megabyte images, all computations execute solely inside your local browser memory.
2. Mathematical Rigor & Academic Verification
Every calculator and algorithm hosted across our suite is grounded in established RFC internet standards and verified economic models:
- JSON Processing: Strict adherence to RFC 8259 syntax parsing and formatting.
- Token Security: RFC 7519 JSON Web Token decoding and cryptographic claim inspection.
- Mortgage Econometrics: Standard compound amortization differential formulas with exact PITI escrow breakdowns.
- Visual Accessibility: W3C WCAG 2.1 relative luminance algorithms ensuring AA and AAA compliance.
3. Sustainability & Non-Intrusive Advertising
We believe high-utility software should remain open and accessible to all without paywalls, subscriptions, or invasive tracking. We partner with Google AdSense to display non-intrusive, privacy-compliant advertisements designed under strict Cumulative Layout Shift (CLS) safeguards to fund server hosting and continuous tool maintenance.
