Privacy and local saving
Last updated: October 3, 2026.
Your plan stays in the browser
Frame labels, wall sizes, frame sizes, positions and hardware offsets are calculated on your device. The application does not upload them, put them into a public link or send analytics events. It has no accounts, photo uploads, advertising scripts, external fonts or payment service.
Automatic local saving
The planner stores the current plan in localStorage under stillwall-plan-v1 when your browser allows it. The save status reports whether this succeeded. Private browsing or storage limits can prevent saving; keep the tab open and print a reference if the page warns that storage is unavailable.
The save belongs to this browser profile and website origin. It is not synchronized across devices or domains. Clearing this site’s browser data removes the saved plan. Reset sample replaces the saved plan after confirmation; it does not delete files you already saved or printed. On a shared device, clear this site’s browser storage when finished.
Printed and saved files
A measurement guide may include your frame labels and dimensions. Printing or Save as PDF is handled by your browser and chosen printer or file destination. Those copies remain under your control; resetting the planner does not remove them.
Ordinary web hosting
Your browser still connects to the site to download its HTML, scripts and styles. The host, reverse proxy or Cloudflare may process IP addresses, browser headers and request information for delivery and security. The supplied application does not write per-request access logs. Infrastructure error logs and the operator’s hosting settings may retain connection data.
No claim is made that visiting a website is anonymous. The operator should review its actual hosting retention and update this notice if it adds analytics, accounts, support collection or other services.
