How these were built (and how your data is handled)

Prompt‑driven development with GPT‑5. Each mini app was planned, specified, and iteratively refined by prompting OpenAI GPT‑5 Thinking to co‑design flows, copy, and edge‑cases.
Local‑only by default. The mini apps store any inputs or preferences in your browser’s Local Storage. There’s no direct GPT‑5 pipeline at runtime and nothing is sent to a server unless a page explicitly states otherwise.
Privacy‑first. Your data stays on your device. You can clear it anytime from your browser settings.
Simple stack. Plain HTML, CSS, and JavaScript you can view‑source and learn from.
