Thomas Schwarz
Plöner Straße 7
23795 Klein Rönnau
Germany
2. Data processed by the app
Training journal
Dates, names of seminars or tournaments, locations, categories, placements, and notes that you enter are stored locally in the app's private storage. The controller does not receive this content.
Settings
The app locally stores settings for speech output and timers, as well as the app version state needed to show information following an update.
Text-to-speech
Selected technique and training terms are passed to the Android text-to-speech engine configured on your device. Depending on the selected TTS engine, its provider may process data. The app does not use the microphone or record audio.
Android backup
Because Android backup and device transfer are permitted, local app data may be included in a backup depending on your device and Google account settings. The controller has no direct control over this processing by the platform provider.
3. Google AdMob and consent
The app uses Google Mobile Ads (AdMob), provided in the European Economic Area by Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. Data processed may include the advertising ID, IP address, approximate location, device and app information, ad interactions, diagnostics, and fraud-prevention data. Google and participating advertising partners may use this data to create profiles for personalised advertising if you consent.
On launch, the app requests the current consent status through the Google User Messaging Platform (UMP). Ads are requested only when UMP indicates that advertising may proceed. Where required, you can choose between personalised and limited or non-personalised advertising. The Privacy options button on the start screen lets you reopen and change your choice with effect for the future.

4. Purposes and legal bases
- Local storage and delivery of the app functions you request: Article 6(1)(b) GDPR.
- Personalised advertising and non-essential access to information on your device: your consent under Article 6(1)(a) GDPR and Section 25(1) TDDDG.
- Contextual advertising, measurement, security, and fraud prevention where legally permitted without consent: Article 6(1)(f) GDPR. The legitimate interests are financing and securely operating the app.
- Handling support requests: Article 6(1)(b) or Article 6(1)(f) GDPR.
5. Recipients and international transfers
Local training data is not intentionally transmitted to the controller or advertising providers. Recipients of advertising and diagnostic data may include Google, its affiliated companies, and the advertising partners identified in the consent message. The TTS engine and backup provider selected on your device may process data under their own terms.
Google and advertising partners may process data outside the EEA, including in the United States. Google states that, depending on the recipient, it relies on safeguards such as adequacy decisions including the EU-US Data Privacy Framework and EU Standard Contractual Clauses.
6. Retention and deletion
Local journal and settings data remains on the device until you delete it in the app, clear the app's Android storage, or uninstall the app. Backup copies may remain for longer under the settings and retention periods of the backup provider. Google and advertising partners retain data under their own practices linked above. Support emails are deleted once the request is resolved unless a legal retention duty applies.
7. Security and automated decisions
Local data is held in the app storage protected by Android. Complete protection against every risk cannot be guaranteed. The app itself does not make decisions that produce legal or similarly significant effects. Personalised ad selection may be automated based on usage and device data.
8. Your rights
Subject to the statutory requirements, you have rights of access, rectification, erasure, restriction of processing, data portability, and objection. You may withdraw consent at any time with effect for the future. You can manage or delete local content in the app or through the Android app settings.
You may also lodge a complaint with a data protection authority. The competent authority is, in particular, the Independent State Centre for Data Protection Schleswig-Holstein (ULD), Holstenstraße 98, 24103 Kiel, Germany, email: mail@datenschutzzentrum.de.
