Our Security Principles
EU-first
Built in Europe, with sovereignty and European regulatory needs in mind.
Transparency
No hidden training, no black boxes. You know where your data goes.
Control
You decide which models, regions, and providers are allowed.
Security through UX

Security Measures
🇪🇺 EU Hosting
All data is processed in the EU by default, with the option to restrict providers outside.
No Third-Party Storage
Content is never stored on model providers' servers.
Zero Training Retention
Your data is never used to train external models.
Encryption
All data encrypted in transit (TLS 1.2+) and at rest (AES-256).
Admin Controls
Model/region allowlists, audit logs, and retention settings give you full control.
PII Redaction
Sensitive personal data is automatically detected and removed before being sent to models.
Content Filtering
Admins can define rules to block or reroute prompts containing sensitive data, with clear feedback to users.
Audit & Alerts
Every action is logged. Get alerts for potential leaks or policy violations.
Security FAQ
What data does Qasten store?
We store the data required to provide the service: user and account information, conversations, saved workflows, and knowledge base entries. All content is encrypted at rest (AES-256) and in transit (TLS 1.2+). Retention policies let you control how long data is kept.
Can I delete my data?
Yes. Every user can delete their own conversations and workflows. Admins can configure retention policies and delete data at the account level, but they cannot read private conversations.
Does Qasten use my data to train models?
No. Never. Your data is never used to train any models. We enforce a Zero Data Retention (ZDR) policy with our AI providers, contractually ensuring they do not store or train on your data.
Where is my data processed?
Qasten is hosted in the EU. As an administrator, you have full control. You can configure your workspace to only use AI providers that are also hosted within the EU, ensuring complete data sovereignty.
Security isn't an add-on. It's the foundation of Qasten.
