Salonized: sovereignty score and 8 European alternatives

Salonized is salon management software for beauty, hair, barber, nail and wellness businesses. It provides an online calendar, a booking widget for websites and social media, sales and stock management, client management, marketing tools and reports. The provider describes its use as managing appointments, sales and clients from any location.

The operating company is Treatwell Salonized NL B.V. in the Netherlands. Treatwell acquired the business in October 2024 and became its sole shareholder; the announcement says the product, team and expertise will be combined with the Treatwell Group. Treatwell itself was bought in 2020 by Real Web, a fund based in Luxembourg. The public pages do not state where customer data is stored, so a European organisation should check this in the privacy statement.

Why digital sovereignty matters with Salonized

Salonized is headquartered in NL and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data. The ultimate owner is based in LU, also within Europe.

Data is hosted exclusively in the EU, so Salonized scores best on data residency.

Salonized 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 Salonized together with your other vendors and gives a total score, a heatmap and the main risk drivers.
