2. Introduction
This Privacy Policy explains how information is collected and used when you use the App. We do not collect names, email addresses, or account data.
Third-party service providers integrated into the App automatically collect certain information. This processing is required for app functionality, analytics, crash reporting, advertising, and purchase management.
3. Age Requirement (13+)
The App is intended for users aged 13 and older. We do not knowingly collect personal data from children under 13. If you are under 13, please do not use the App.
4. Information We Do Not Collect
We explicitly confirm that we do not request, collect, or store:
Your name, email address, or phone number
Your physical address
User accounts or login credentials
5. Information Collected by Third Parties
The App uses third-party providers that automatically collect the following data types for the purposes described in Section 6:
Identifiers: Device identifiers (GAID/IDFA), Installation IDs, and IP addresses
Commercial Information: Purchase history and subscription status (via RevenueCat)
Usage and Diagnostics: App interactions, crash logs, and performance metrics
Location: Approximate location (derived from IP address) for advertising relevance
6. Legal Basis for Processing (GDPR)
Consent: Used for personalized advertising (AdMob). For EU users, consent is requested via an in-app dialog when first launching the App. You may withdraw consent at any time by:
Navigating to Settings (gear icon in the upper right corner)> Privacy preferences in the App to modify your choice, or
Using device settings to disable tracking entirely (Section 10)
Legitimate Interests: Used for crash reporting (Firebase), analytics, and fraud prevention.
Contract Performance: Used for processing your purchases (RevenueCat).
7. Third-Party Service Providers
We advise you to review their privacy policies:
Google AdMob: https://policies.google.com/privacy
Google Firebase: https://firebase.google.com/support/privacy
RevenueCat: https://www.revenuecat.com/privacy
Note: Google AdMob works with numerous advertising partners who may also process your data. You can view Google's advertising partners at:
https://support.google.com/admob/answer/9012903
Data Transfers: These providers may transfer data to the USA. Such transfers are protected by the EU-U.S. Data Privacy Framework (for Google) or Standard Contractual Clauses (for RevenueCat).
8. Data Retention & Deletion
We do not store personal data ourselves.
AdMob/Firebase: Data is retained according to Google's policies
RevenueCat: Purchase history is retained to allow you to restore your subscription. Note that financial transaction records are retained for 7 years to comply with tax and accounting obligations (Bundesabgabenordnung), even if you request deletion of your user profile.
8.5 Automated Decision-Making
The App does not use automated decision-making or profiling that produces legal effects or similarly significantly affects you.
Note: Ad personalization by Google AdMob is based on automated processing, but you can opt out at any time (Section 10).
9. Your Rights Under GDPR
You have the following rights: Access, Rectification, Erasure, Restriction, Objection, Data Portability, and Withdrawal of Consent.
Technical Limitation:
We do not collect identifying information (name, email, or account). Therefore, we cannot identify individual users in third-party systems.
How to Exercise Your Rights:
Advertising & Analytics Data:
Reset your Advertising ID in device settings (Section 10). This immediately dissociates your device from past data.
Purchase Data:
Transaction records are retained for 7 years as required by Austrian tax law (BAO §132) and cannot be deleted under GDPR Article 17(3)(b).
Apple and Google maintain separate payment records. To request deletion:
- Apple: https://privacy.apple.com
- Google: https://support.google.com/googleplay/answer/7018481

10. Ad Preferences & Privacy Controls
You cannot disable advertisements entirely without purchasing the ad-free version of the App. However, you can control how your data is used for advertising:
Opt-Out of Personalized Ads (Stop Tracking)
You may choose to stop seeing ads based on your interests. You will still see the same number of ads, but they may be less relevant.
In-App (EU/UK Users): Go to Settings (gear icon in the upper right corner) > Privacy preferences to reopen the consent dialog. Withdrawing consent is as simple as granting it—just select your preference and confirm.
iOS Device Settings: Go to Settings > Privacy & Security > Tracking and toggle off permission for this App.
Android Device Settings: Go to Settings > Privacy > Ads > Delete Advertising ID.
Remove Ads Entirely
To stop seeing advertisements completely, you must purchase the Ad-Free / Pro version via the in-app purchase option.
Reset Your Ad Profile
You can reset your "Advertising ID" in your device settings. This dissociates your device from your past ad history, effectively treating you as a new, anonymous user.
11. Changes to This Privacy Policy
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last updated" date.
For material changes affecting your rights, we will:
Update the "Last updated" date at the top of this policy

Your continued use of the App after changes constitutes acceptance of the updated policy.
