Note for Windows users – 14-day trial
Our Windows installers are digitally signed using Microsoft Artifact Signing (Public Trust). With new or not yet widely used installer versions, Microsoft Defender SmartScreen may still display “Windows protected your PC” when an installer is launched for the first time.
If you downloaded the installer directly from leadershipperformancesystems.com, you can continue via “More info” → “Run anyway”. For installers that have already been signed, Leadership Performance Systems is shown as the verified publisher.
You can also verify the digital signature via right-click the EXE → Properties → Digital Signatures.

Trial and licensing model
One-off payment with no automatic renewal.
14-day local trial · one named user · up to two personal devices · no automatic renewal.
Licence status and updates: When an internet connection is available, the application may check the status of the installed licence and the availability of a newer program version covered by the existing product and licence scope in the background with the LPS system. If such a version is available, the application displays this and offers a download. You decide whether and when to download and install the new version; installation is not automatic. Alternatively, the current installer can be obtained through the download area provided for the product. Without an internet connection, this supplementary check is not performed; normal desktop use with a valid local licence remains possible. Downloads, customer-portal access and individual product-related online functions may require an internet connection.

Frequently asked questions
Important questions before trial and purchase.
Is the application limited to Spencer-Brown forms?
No. It specialises in form calculi and re-entry structures while also supporting flexible relational modelling and SVG editing.
Can I continue projects later?
Yes. Projects are stored locally as JSON files and can be loaded again.
Does the application validate academic correctness?
No. The studio is a construction and visualisation tool; sources, interpretation and subject-matter correctness remain the user’s responsibility.
