No advisory promise
Mietfolio helps with organization and exports, but does not replace individual legal or tax advice.
What does Mietfolio cost?
The start is free. If paid plans are activated, price, scope and term are shown clearly before booking.
Who is Mietfolio for?
Private landlords and small property managers who want service charges, documents, tenant communication, smoke alarms and reminders in one place.
Can I manage multiple properties?
Yes. Mietfolio works with an active property context, so records and tasks stay separated by property.
What can the tenant portal do?
Landlords can invite tenant access, share selected documents, review uploads, answer portal messages and enable smoke-alarm maintenance self-service.
Where is the data stored?
Mietfolio uses Supabase for authentication, database and storage, including edge functions and storage. The German privacy policy contains the full processor and region details.
Does Mietfolio replace legal or tax advice?
No. Mietfolio helps with structure, documentation and preparation, but it does not replace individual legal or tax advice.
