Terms of Use

DiagramLens for macOS · Last updated 16 October 2026

1. Agreement

DiagramLens ("the App") is published by VTEK Solutions Limited ("we", "us"). By downloading or using the App you agree to these Terms and to Apple's Licensed Application End User License Agreement (the "Standard EULA"), which governs all apps distributed through the Mac App Store. If these Terms and the Standard EULA conflict, the Standard EULA prevails.

2. Licence

We grant you a personal, non-transferable, non-exclusive licence to use the App on any Mac that you own or control, as permitted by the Mac App Store usage rules. You may not copy, modify, reverse-engineer, decompile or redistribute the App except where the law expressly allows it.

3. Free trial and purchase

4. What the App does and does not do

The App is a read-only viewer. It never modifies the files you open. Rendering is intended to be faithful to the original drawing, but some features of the Microsoft Visio® file formats are not supported and fonts that are not installed on your Mac are substituted; the App's "Faithful rendering" claim is not a guarantee of pixel-exact reproduction for every file.

5. Your content

You keep all rights to the drawings you open. The App processes them only on your Mac and never transmits them. You are responsible for having the right to open and use any file you load into the App.

6. Updates and availability

We may update the App to fix problems, add features or meet platform requirements, and we may stop offering it at any time. Updates are delivered through the Mac App Store.

7. Disclaimer of warranties

To the fullest extent permitted by law, the App is provided "as is" and "as available", without warranties of any kind, whether express or implied, including merchantability, fitness for a particular purpose and non-infringement. We do not warrant that the App will be error-free or that every Visio file will render correctly.

8. Limitation of liability

To the fullest extent permitted by law, we will not be liable for any indirect, incidental, special, consequential or punitive damages, or for any loss of data, profits or business, arising from your use of the App. Our total liability for any claim relating to the App is limited to the amount you paid for it. Nothing in these Terms limits liability that cannot be limited by law, including liability for death or personal injury caused by negligence, or your statutory rights as a consumer.

9. Trademarks

Microsoft and Visio are trademarks of the Microsoft group of companies. DiagramLens is an independent product and is not affiliated with, sponsored by or endorsed by Microsoft. Apple, Mac and App Store are trademarks of Apple Inc. DiagramLens and its icon are our trademarks.

10. Governing law

These Terms are governed by the laws of England and Wales, and the courts of that jurisdiction have exclusive jurisdiction, except that consumers in other countries keep the protection of mandatory local law.
