This privacy policy applies solely to the app ‘CatAche Diary’, created by Crunchy Cracker.
Crunchy Cracker respects the privacy of all users of its services and ensures that all personal information is treated confidentially.
Crunchy Cracker is not responsible for the privacy policy of other websites and sources. By using this app you agree to accept the privacy policy.
This app (“we”, “our”, or “us”) does not collect, store, or share any personal information or user data.
Information We Do Not Collect
CatAche Diary is designed with your privacy as a top priority. We do not collect:
- Any data transmitted to our servers — because we have none
- Personal identification information (name, email, phone number, etc.)
- Account credentials — no login or registration is required
- Location data
- Device identifiers or advertising IDs
- Usage analytics or crash reports
Data you enter into the app
CatAche Diary allows you to log headache episodes including details such as date, time, duration, severity, symptoms, triggers, and notes. Free usage is limited to 10 episodes; a one-time in-app purchase unlocks unlimited logging. This data is:
- Fully under your control at all times
- Stored exclusively on your device using local device storage
- Never transmitted to any external server, cloud service, or third party
- Never accessed by the app’s developer or any other party
Data Export (PDF & CSV)
CatAche Diary provides the option to export your headache episode data as a PDF or CSV file. Please note:
- Exported files are generated entirely on your device
- Files are saved to a location of your choosing on your device
- We do not receive a copy of exported files
- Once exported, your data is subject to the privacy and security settings of the app or service you choose to open or share the file with — please exercise caution when sharing health-related files
In-App Purchases
CatAche Diary is free to download and allows you to log up to 10 headache episodes at no cost. A one-time in-app purchase is available to unlock unlimited episode logging.
Important details regarding purchases:
- For questions about billing, refunds, or payment issues, please contact Apple or Google directly through their respective support channels

Third-Party Services
CatAche Diary does not integrate with analytics platforms, advertising networks, or data brokers. However, the in-app purchase functionality is facilitated by the following platform payment services:
- Apple App Store — applicable when using CatAche Diary on iOS. Apple’s Privacy Policy is available at https://www.apple.com/legal/privacy/
- Google Play — applicable when using CatAche Diary on Android. Google’s Privacy Policy is available at https://policies.google.com/privacy
These services may collect information related to your purchase transaction in accordance with their own privacy policies. We encourage you to review them.
Children’s Privacy
CatAche Diary does not knowingly collect any information from users of any age, including children under the age of 13. As no data is collected or transmitted, there is no risk of inadvertent collection of children’s data.
Your Rights (EU/EEA Users)
Even though we collect no personal data, EU and EEA residents have rights under the General Data Protection Regulation (GDPR), including the right to access, rectification, erasure, and portability of personal data, and the right to object to processing. Since this app processes no personal data, none of these rights are applicable in practice. If you have questions or concerns, you may contact us at hello [at] crunchycracker.com, or lodge a complaint with the Dutch Data Protection Authority (Autoriteit Persoonsgegevens) at autoriteitpersoonsgegevens.nl.
Data Security
Because all data is stored locally on your device, its security depends on your device’s own security measures (such as screen lock, device encryption, and operating system protections). We recommend keeping your device’s operating system and security settings up to date.
If you lose your device or uninstall the app, locally stored data may be permanently lost. We recommend using the export feature to keep backups of your records.
Your Rights and Control
You have complete control over your data at all times:
- View all your data directly within the app
- Export your data at any time in PDF or CSV format
- Delete individual records or all data by uninstalling the app
Since we do not hold your data, there is nothing for us to provide, correct, or delete on our end.
Changes to This Privacy Policy
We may update this Privacy Policy from time to time. When we do, we will update the effective date at the top of this page. We encourage you to review this policy periodically. Continued use of CatAche Diary after changes constitutes your acceptance of the updated policy.
