Privacy Policy

1. Data Controller

Controller: Michael Murr. Contact: contact@michaelmurr.de

2. What Data We Collect

Input data: dimensions, wood types, project names, and cut lists are processed locally on your device.

Feedback & Suggestions: If you use the feedback feature, your suggestions and votes are transmitted to our server. A pseudonymous Device ID is sent to prevent abuse and duplicate voting. This ID is not linked to direct personal data.

Technical data: No crash-reporting or analytics services are used at this time. If services such as Firebase or Sentry are added in the future we will disclose that here.

3. In-App Purchases and Subscriptions via RevenueCat

We use the "RevenueCat" service in our app to manage, validate, and restore in-app purchases and subscriptions. The provider of this service is RevenueCat, Inc., 1032 E Avenue J Ste Z4 #133, Lancaster, CA 93535, USA.

If you make a purchase in our app, start a subscription, or check the status of a subscription, the app connects to RevenueCat's servers. In doing so, data is transmitted to RevenueCat in order to verify the transaction and unlock the purchased content for you.

Processed data:

  • Anonymized user ID (App User ID)
  • Information about purchase and subscription status (receipts/proof of purchase)
  • Device information (e.g. operating system, app version)
  • IP address (for technical reasons related to server communication)

Legal basis:

The processing of this data is necessary for the performance of a contract or in order to take steps prior to entering into a contract. The legal basis is Art. 6(1)(b) GDPR (performance of a contract). Without this data processing, we cannot technically provide in-app purchases and subscriptions to you.

Data transfer to a third country & data processing agreement:

RevenueCat processes your data on servers in the United States. We have concluded a data processing agreement with RevenueCat in accordance with Art. 28 GDPR. For transfers to the United States, RevenueCat relies on the adequacy decision of the European Commission (EU-US Data Privacy Framework) as well as EU Standard Contractual Clauses in order to ensure an adequate level of data protection. Further information about RevenueCat's data processing can be found in its privacy policy: https://www.revenuecat.com/privacy/

4. Feedback and Feature Request Function

We offer you the option in our app to send us suggestions for improvement or feature requests via a form.

Processed data and purpose:

If you use this function, we collect the title and description of your request that you enter. We use this data exclusively to improve our app and our services.

In addition, you may voluntarily provide your email address. If you do so, we will use your email address only to contact you with any follow-up questions regarding your suggestion or to inform you about its implementation. Your email address will be treated confidentially and will not be published.

Legal basis:

The processing of the title and description is based on our legitimate interest in the further development and improvement of our app (Art. 6(1)(f) GDPR).

The processing of your voluntarily provided email address is based on your consent (Art. 6(1)(a) GDPR), which you give by entering and submitting your email address. You may revoke this consent at any time with future effect, for example by contacting us via email.

Retention period:

The transmitted data will be deleted as soon as it is no longer required for the purpose for which it was collected, for example when the feature has been implemented or rejected, or when you revoke your consent to store your email address, provided that no statutory retention obligations apply.

Processor (hosting):

The data entered as part of the feedback function is stored on servers of our hosting service provider, netcup GmbH, Daimlerstrasse 25, 76185 Karlsruhe, Germany. The data processing takes place exclusively in Germany. We have concluded a data processing agreement with netcup GmbH in accordance with Art. 28 GDPR in order to ensure the secure handling of your data.

5. Legal Basis for Processing

Contractual necessity: Processing of measurements is necessary to provide the service. Processing of feedback data is based on our legitimate interest (Art. 6(1)(f) GDPR) to improve the app and prevent abuse.

6. Data Storage and Retention

Local vs. Cloud: Projects and measurements are stored only locally on your device. Feedback data is stored on our servers in the EU.

7. User Rights (GDPR)

Rights: Right to access, right to erasure (right to be forgotten), right to rectification, and right to information about stored data. Please direct requests to contact@michaelmurr.de.
