2. Your invoice data stays on your device

Everything you enter in the invoice editor (your business details, clients, line items) is processed only in your browser. Invoices, the PDF and the ZUGFeRD e-invoice are created on your device. Your business details and saved invoices are stored in your browser's local storage (localStorage) and are not sent to us. You can delete them at any time by clearing your browser data. So that the editor also works offline, your browser stores program files (no invoice data) in its cache. A backup file is created on your device only when you request it and is not sent to us.

3. Hosting and server logs

This website is hosted by Vercel Inc., 440 N Barranca Ave #4133, Covina, CA 91723, USA. When you visit the site, the host automatically processes technically necessary data (IP address, date and time, page requested, browser type) to deliver the site and keep it secure. Legal basis: Art. 6(1)(f) GDPR (legitimate interest in a secure, working website). Data may be transferred to the USA; the host is certified under the EU-US Data Privacy Framework.

4. No cookies, no tracking

We do not use cookies, analytics or advertising tools. Fonts are served from our own server; no connection to Google is made.

5. Note suggestion

Only when you click “Suggest”, the business name from the form is sent to our server so that a payment-terms note can be drafted. If this feature is enabled, the request is processed by Anthropic PBC (USA) as our processor. No other invoice data is transmitted. Legal basis: Art. 6(1)(b) GDPR (providing the function you requested).

6. WhatsApp

“Send via WhatsApp” only opens a link to WhatsApp (Meta Platforms Ireland Ltd.) with the invoice number, amount and a link. Data reaches WhatsApp only when you click and send it yourself.

7. Feedback form

If you send us feedback via the form, we receive your message, the features you selected, the language of the page and, only if you enter it, your email address. We use this data solely to read your feedback, improve Rechnaro and reply to you if you wish. The message is delivered to us by email via Resend Inc. (USA) as our processor; Resend is certified under the EU-US Data Privacy Framework. Legal basis: Art. 6(1)(f) GDPR (legitimate interest in improving our service) and, if you ask for a reply, Art. 6(1)(b) GDPR. We delete feedback once it is no longer needed, at the latest after 24 months.

8. Your rights

You have the right to access, rectification, erasure, restriction of processing, data portability and to object (Art. 15 to 21 GDPR). You can also lodge a complaint with a data protection supervisory authority.
