SIGNAK is a web application from ALPICAPTURE SA in Vevey for viewing and analysing point clouds from LiDAR and photogrammetric captures. Everything runs in the browser, with no installation and no local GPU. It reads E57, LAS/LAZ, PLY and XYZ among other formats and offers linear and volumetric measurements, dynamic sections, annotations and comparison of captures from different dates. Export to IFC for BIM is possible, access rights can be set in detail and an API supports integration with BIM and GIS systems. Uses include building surveys, structure inspection, construction progress and heritage documentation.

ALPICAPTURE SA is a Swiss company. According to its legal notice, customers' digital twins are hosted at AlpiVault, a data centre in Switzerland run by an independent partner company. The privacy policy refers to the Swiss nLPD and the GDPR. Switzerland is not an EU member state but is an EFTA country with an EU adequacy decision.

Why digital sovereignty matters with SIGNAK

SIGNAK is headquartered in Switzerland and falls under Swiss law, including the revised Swiss data protection act. Switzerland is not an EU member, but the European Commission recognises its level of data protection as adequate. Its Swiss headquarters does not by itself bring it under US legislation such as the CLOUD Act.

SIGNAK hosts data in Switzerland only. Switzerland is not part of the EU or the EEA, so the GDPR does not apply there directly; the European Commission does recognise Swiss data protection as adequate, so personal data can go there without extra safeguards. Our model therefore scores it between EU hosting and hosting outside Europe. If you require strictly EU hosting, take this into account.

SIGNAK is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs SIGNAK together with your other vendors and gives a total score, a heatmap and the main risk drivers.
