Quality notes

Clear pages, clear limits and no unnecessary clutter

The site is organised around complete tool pages with direct navigation, visible contact information and simple explanations for how each tool should be used.

Calculators are provided for planning and educational use. Financial tools should be treated as estimates only, and each detailed tool page should list the assumptions or official sources used for that calculation.

Focused pages: each tool is linked from the homepage and serves one practical purpose.

Privacy aware: browser-first tools avoid uploads where possible, while upload tools explain when remote storage is used.

Site trust: About, Contact and Privacy pages are kept in the main navigation and footer.
