Frequently asked questions
Are the free tools really unlimited?
We are in launch phase. All features are open for free to gather feedback from Luxembourg professionals. Pro tier will move to €29/month once the platform stabilizes — early adopters will keep preferential access.
Why create an account if it's already free?
An account lets you save your simulations in the cloud (accessible from any device), export professional PDF reports and customise your profile on generated documents.
Is my data secure?
Your data is hosted in Europe on secure servers (Supabase). We do not sell or share your information. Without an account, nothing leaves your browser.
When will the Pro tier be available?
The Pro tier is under development. Contact us at contact@tevaxia.lu to be notified at launch or to discuss your specific needs.
Can I use tevaxia for official valuation reports?
The tools provide indicative calculations. The Pro tier will include customisable EVS 2025 compliant reports. For a certified valuation report, a qualified valuer is still required.
