Your Data Belongs to You.
Your invoices, contracts, and personal documents belong to you - not me, not advertisers, not anyone else. Here is exactly what happens with your data.
- Hosted in Germany
- Your files and database live in Frankfurt, the app servers run in Falkenstein, both ISO 27001 certified. Text recognition (OCR) runs on Google Cloud in the EU, AI models in Microsoft's EU data centers. The few services outside the EU (for example email delivery and push notifications) are listed in the privacy policy.
- No AI training
- Your content is never used to train AI models. Strict data processing agreements with all providers. No exceptions.
- Clear deletion rules
- You can delete documents and your whole account at any time. Deleted documents stay in the trash for 30 days, backups are overwritten after 7 days. The exceptions (for example GoBD retention periods and invoices I have to keep) are listed in the privacy policy.
Stored in Germany. Processed in the EU.
Your files and database are stored in Frankfurt. The app servers in Falkenstein run the document pipeline. Text recognition (OCR) runs on Google Cloud Vision: processing in the EU, a data processing agreement, no training on your data. Digital PDFs with a text layer are read directly in Falkenstein. For AI analysis, only the extracted text is sent over encrypted links to Microsoft Azure OpenAI: the resource sits in Frankfurt, the models run in Microsoft's EU data centers (EU Data Zone). Results are stored back in Frankfurt.
