Your opening dimensions

The calculator stores your opening dimensions in this browser tab’s session storage and performs the comparison in your browser. Dimensions are not included in the calculator URL, analytics events, or feedback unless you choose to type them into a message. Session storage normally clears when the tab is closed; you can also clear site data in your browser.

Analytics

ExactFit uses Google Analytics 4 for page views and interactions such as form use, model visits, and evidence clicks. Analytics event parameters are restricted to model identifiers, field names, error categories, and link types. Exact opening dimensions, email addresses, and free-text feedback are excluded.

Page-location reporting omits query parameters. Google Analytics may use cookies and process browser, device, and network information under Google’s privacy practices. Browser privacy controls or blockers may prevent collection.

Feedback and internal records

Feedback is stored separately from Google Analytics. The server stores your submitted message, an optional helpfulness answer, an anonymous per-tab identifier, timestamps, and any model, measurement, displayed value, and page context included with a measurement report. Authorized administrators can review and export these records.

You may optionally provide an email address and consent to its storage if you want a reply. The email is stored with the feedback record, is available only to authorized administrators, and is not sent to Google Analytics. Internal event and feedback retention is configured by the site operator; the current default is 180 days. Hosting logs and Google’s analytics retention are managed separately. Do not submit passwords, payment information, or other sensitive data.

Manufacturer and other source links open only when selected. Those sites have their own privacy practices.
