What this website does

This website offers product information, practical guides, an interactive calculator, planning tools and local photo utilities. It has no sign-up form, checkout, user-upload feature or third-party analytics script.

Calculator and planner

Calculator inputs, storage estimates and checklist choices are processed in your browser. This site’s code does not send those values to a server or save them in browser storage. Use the public example equation in the product walkthrough, rather than a real personal entry sequence.

Local photo utilities

The resize, compression, conversion, redaction, crop, watermark and image-inspection tools read only the image you select in your browser. This website’s code processes its pixels locally, creates a separate downloadable copy and does not upload the selected photo or save it in browser storage. Clear the photo or close the page when finished. Downloaded files remain wherever your browser saves them. The original file is not modified.

Hosting and external links

The hosting provider handles ordinary page requests and access controls. These notes do not replace the provider’s privacy terms. External links, including App Store and documentation links, leave this website and are subject to the destination’s policies.

Scope of these notes

This page describes interactions with the CalcLock website. Permissions and information presented inside an app are separate from the browser tools described here.
