The material on this website is provided for general informational purposes. It describes the LStore platform, the services Unique Checksum offers, and the firm’s areas of expertise, to help institutions evaluate whether a conversation with Unique Checksum is worthwhile.

Technical specifications, capabilities, configurations, and roadmap statements are described as accurately as the firm is able at the time of writing, but are subject to change and are not guarantees. Third-party product specifications reproduced here are the published figures of the manufacturer concerned and are stated for maximum configurations; an actual deployment is sized to workload. Nothing on this site is a binding offer or a commitment to deliver any particular specification, performance level, or outcome.

How this website is built

As published, this website is static. It sets no cookies, uses no web analytics and no tracking of any kind, and stores nothing in your browser. It contains no forms, and it makes no network request that reports back to Unique Checksum what you have looked at.

The search box

Site search runs entirely inside your browser, against an index embedded in the page you are already reading. What you type into it is not transmitted anywhere and is not recorded.

Typefaces served by Google

The typefaces used on this site are loaded from Google Fonts (fonts.googleapis.com and fonts.gstatic.com). Requesting them discloses your IP address and basic browser information to Google, under Google’s own terms. This is the only third-party disclosure the site makes, and it is stated here because a privacy notice that omitted it would be incomplete.

Contacting Unique Checksum

The only contact mechanisms on this site are direct email links, which open a message in your own email application. Using them is entirely at your initiative, and anything you choose to send arrives as ordinary email.

Information you send is not sold or traded

Unique Checksum does not sell, trade, or otherwise make available to any party outside the firm the information you provide when you make contact. It is used to respond to you and for nothing else.

Request-submission features

This site does not yet offer the ability to submit requests through it. Should such features be introduced, the terms governing how the information you provide is handled — including any consent required before a request is passed to a solution partner for fulfillment — will be published on this page before those features go live, not afterwards.

This website links to a small number of third-party resources — research papers, open-source projects, standards documentation, and institutional websites — to support the accuracy of its descriptions. Unique Checksum does not control these external sites and is not responsible for their content, availability, accuracy, or practices. A link does not constitute an endorsement of the linked site beyond the descriptive purpose for which it is provided.

Unique Checksum is committed to making this site usable by as many people as possible, and is working toward conformance with the Web Content Accessibility Guidelines (WCAG) 2.2 at Level AA — the benchmark that also satisfies the U.S. Section 508 and ADA Title II standards, and the reference standard behind the European Accessibility Act.

Measures already in place include keyboard-operable navigation with a skip-to-content link and visible focus indicators, a semantic page structure with landmark regions and a single clear heading hierarchy on each page, text alternatives for every image and descriptive labels for the architecture diagrams, and body-text color contrast that meets or exceeds the Level AA threshold.

This is an ongoing effort, and it is worth being plain about its limits. Conformance has not yet been independently verified across every page, some items remain in progress, and a full manual keyboard and screen-reader review is planned rather than complete. Anyone who encounters a barrier to accessing part of this site, or who needs information in an alternative format, may write to webmaster@uniquechecksum.com, and the matter will be addressed.

Questions about intellectual-property or trademark matters, privacy and data handling, or the terms under which this site’s material may be used, may be directed to legal@uniquechecksum.com. General inquiries are best routed through the contact page.
