PRIVACY

A small amount of local storage.

This release has no accounts, advertising scripts, analytics service or contact form.

Your comparison list

Your selected system configurations are stored in your browser’s localStorage so that the shortlist survives a page reload. Clear the list using its remove controls or clear site data in your browser. The site does not use tracking cookies.

Search and shared links

Model searches, filter settings and comparison identifiers appear in page URLs. Opening or sharing those URLs sends those terms to the web server. Avoid entering personal information in a model search. Replacement prices and daily-use inputs stay in the current page and are not submitted to the server.

Operational requests

A hosting provider may process IP addresses and request information to deliver pages and diagnose errors. This application does not maintain a visitor-profile database. Infrastructure log retention depends on the deployed hosting configuration.

Links to other sites

Source and manufacturer links open third-party websites with their own privacy practices. This site does not control those websites.

Policy version: September 21, 2026. Review this notice if tracking or account features are added.
