Usage analytics
The App works fully offline and does not require user registration.
Solfeggio is intended for use by children under the age of 13.
We comply with the Children’s Online Privacy Protection Act (COPPA).
Because we do not collect any personal information from users, including children, we do not:
Request personal data
Enable account creation
Track user behavior
Use analytics
Display third-party advertisements
If you believe a child has provided personal information to us, please contact us immediately at songliang.cheung@gmail.com, and we will address the issue promptly.
For users located in the European Union (EU), we comply with the General Data Protection Regulation (GDPR).
Since Solfeggio does not collect or process personal data:
No personal data is stored
No data is shared with third parties
No data processing occurs
Therefore, data access, correction, or deletion requests are not applicable.
The App may contain a donation page that provides external links to third-party payment services such as:
PayPal
Satispay
If you choose to make a donation, you will be redirected to the respective third-party website or application.
We do not:
Collect payment information
Process transactions
Store financial data
All payment processing is handled directly by the third-party provider according to their own privacy policies.
We encourage you to review their privacy policies before submitting any information.
Because Solfeggio does not collect or store user data, there is no user data stored on our servers.
We may update this Privacy Policy from time to time. Any updates will be posted with a new effective date.
