IK Studios
Legal & Trust Center
One calm home for how IK Studios handles privacy, security, terms, and intellectual property — for our websites and for the products we build, starting with Vault One.
Overview
IK Studios is an independent software studio based in the Netherlands. We design and operate digital products with a privacy-first, device-first mindset. Our flagship and currently only public product is Vault One, a private personal-finance app for Mac.
This Legal & Trust Center covers IK Studios as a company and the websites we run, such as ikstudios.nl. Product-specific terms, privacy details, and security architecture for Vault One live in the dedicated Vault One Trust Center, which these documents link to rather than duplicate.
Everything here is written to match what we actually build today. Where a capability is planned but not yet live, we say so plainly instead of implying it exists.
