Privacy Policy
Last updated: January 2026
This Privacy Policy explains how Rainer Feest (“we”, “our”, “us”) operates the invoicing mobile application (“App”).
Your privacy is extremely important to us. The App has been designed to work without collecting personal data on external servers.
1. Data Processing
The App does not operate any backend server and does not transmit your data to us or any third parties.
All information entered into the App (including customer data, invoices, and business information) is stored locally on your device
and, if enabled by you, securely synchronized via Apple iCloud.
2. iCloud Synchronization
If iCloud is enabled on your device, Apple may synchronize your data between your devices.
Apple processes this data under its own privacy policy and data protection terms.
We have no access to your iCloud data.
3. No Accounts / No Tracking
- No user account is required.
- No analytics, tracking, or advertising technologies are used.
- No personal data is collected, transmitted, or sold.
4. Payments
The App does not process payments, subscriptions, or in-app purchases.
5. Your Rights
Because all data remains under your sole control on your own device and iCloud account, you can delete all personal data at any time
by deleting the App or disabling iCloud synchronization.
6. Contact
