Effective Date: April 9, 2026
We respect your privacy and are committed to protecting your personal data. This policy explains how we collect, use, and safeguard information when you use our website or iOS application.
Optional Email Address (Website & iOS App): If you choose to provide your email address when submitting a constant or sending feedback, we will store it solely for the purpose described below. Providing an email address requires your explicit consent.
Optional Technical Feedback Data (iOS App): When submitting feedback through the iOS app, you may optionally consent to including your current app version and iOS version alongside your feedback. This data is only collected with your explicit, separate consent.
Where you have consented to both an email address and technical feedback data, these may be stored in association with each other in order to follow up on your feedback.
Email Address: Only to send updates about your submission or feedback (e.g., confirmation, follow-up questions, or status changes).
Technical Feedback Data: Only to understand the technical context of your feedback and improve the iOS application accordingly. This data is not used for any other purpose.
All personal data described in this policy is processed exclusively on the basis of your freely given, specific, and informed consent (Art. 6(1)(a) GDPR / DSGVO). Each type of data requires a separate opt-in. You may withdraw your consent at any time; withdrawal does not affect the lawfulness of processing carried out prior to withdrawal.
We do not share your data with third parties, except as required by law.
Email Address: Retained until you unsubscribe or request deletion.
Optional Technical Feedback Data (App Version, iOS Version): Retained only for as long as necessary to process and act on the associated feedback, after which it is deleted.
Under GDPR / DSGVO, you have the right to:
- Access the personal data we hold about you.
- Request correction or deletion of your data.
- Withdraw consent at any time, without affecting the lawfulness of prior processing.
- Object to or request restriction of processing in applicable circumstances.
- Data portability where technically feasible.

We implement reasonable security measures to protect your data from unauthorized access or disclosure.
We may update this policy. Changes will be posted on this page, and significant updates will be communicated via email if applicable.
