5. Custom Mail Server (SMTP)

If you connect your own SMTP mail server, emails are sent via your own infrastructure. In this case the SMTP server operator bears independent responsibility for that data processing. offerra stores SMTP credentials in encrypted form.

6. Push Notifications

If you enable browser push notifications, a device token is transmitted through your browser's push service (e.g. Google FCM for Chrome, Mozilla for Firefox) to our servers. Activation occurs only on your explicit request. Legal basis: Art. 6(1)(a) GDPR.

7. Cookies and Local Storage

We use technically necessary cookies for authentication and session management (legal basis: Art. 6(1)(b) GDPR). PostHog analytics cookies are only set with your consent. Your cookie preference is stored in your browser's local storage.

8. Retention Periods

Personal data is deleted once the purpose of processing has lapsed and no statutory retention obligations apply. Account data is deleted within 30 days of cancellation. Billing records are subject to the statutory 10-year retention period.

9. Your Rights

Under GDPR you have the right to access (Art. 15), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18), data portability (Art. 20), and objection (Art. 21). You may withdraw consent at any time with effect for the future. Contact us at: datenschutz@offerra.de

10. Right to Lodge a Complaint

You have the right to lodge a complaint with a data protection supervisory authority. The competent authority depends on your place of residence or the company's registered office.
