Privacy – Waffensachkunde Kompakt

1. Controller

Christian Hermann & Martina Hermann GbR, An Rainen 3, 72525 Münsingen, Germany; email: apps@bitbeans.de.

2. Data processed

Learning progress, quiz results, settings and started exercises are processed locally or assigned to the signed-in account, depending on the feature.

For purchase verification and restoration, we process product ID, store platform and technical receipt data.

When the optional AI coach or AI exam analysis is used, the question or relevant answers and learning material are sent through our backend to xAI (Grok). Account and payment data is not sent for this purpose. Do not enter personal data in free-text fields.

3. Purposes and legal bases

We process data to provide the app, verify purchases, deliver online features you actively use, maintain security, resolve errors and answer voluntary requests. Depending on the operation, the legal bases are Article 6(1)(b), (f) or, where expressly requested, (a) GDPR.

4. Recipients and service providers

We use Cloudflare for backend, database, media and security, Firebase/Google for sign-in, and Apple and Google for store services. xAI (Grok, api.x.ai) is used only when the optional AI feature is requested.

5. International transfers

Some providers may process data outside the EU or EEA. Where no adequacy decision applies, transfers rely on appropriate safeguards, in particular EU Standard Contractual Clauses, or on applicable statutory exceptions.

6. Advertising and tracking

The app contains no third-party advertising. We do not create advertising profiles, sell personal data or use advertising tracking.

7. Retention and security

Local data remains on the device until it is removed in the app or through system settings. Server data is retained only for as long as required for the respective function, security and statutory evidence. Transfers are encrypted.

8. Delete data and account

Local data can be removed in the app or through the device’s system settings. Where an account or cloud data exists, deletion can be requested in the app or by emailing apps@bitbeans.de. Store purchases are managed separately by Apple or Google.

9. Your rights

Subject to the statutory requirements, you have rights of access, rectification, erasure, restriction, portability and objection. Consent can be withdrawn for the future. You may also lodge a complaint with a data-protection authority; the LfDI Baden-Württemberg is the authority responsible for our registered office.
