Data sovereignty & GDPR
Data in your own house
Your app runs on your infrastructure in the EU. Your business and customer data sit where you decide β not in a foreign, possibly non-European cloud whose access and laws you don't control.
Auditable & GDPR-compliant
Because you control data and code, the app can be operated cleanly in compliance with the GDPR: traceable access via the permission system, an audit log over changes, defined retention and deletion rules, information and export functions for data-subject rights. For maintenance access involving personal data we conclude a data processing agreement (DPA) under Art. 28 GDPR.
No foreign roadmap
You're not at the mercy of a third party's pricing or feature policy and not dependent on the failure of a foreign platform. What your app can do, where it sits and where it evolves you decide.
Why this matters for regulated industries
Especially in areas with sensitive data β health, finance, government β sovereignty over location and access is often a prerequisite. A self-hosted app meets this requirement from the ground up, instead of having to explain it after the fact.
