Changes to Your Data

You have complete control over your data:

Your Rights

Since sTrain does not collect or process your personal data, traditional privacy rights (access, deletion, portability) are automatically fulfilled:

• Right to Access: All your data is accessible within the app at all times
• Right to Rectification: Edit any data directly in the app
• Right to Deletion: Simply delete data within the app or uninstall the app

International Users

sTrain can be used worldwide. Since no data leaves your device:

• No data crosses international borders
• No data residency regulations apply
• GDPR, CCPA, and other privacy laws are naturally compliant (no data collection = no privacy concerns)

Legal Basis for Processing (GDPR)

For users in the European Economic Area (EEA):

Since sTrain does not collect or process personal data, GDPR requirements regarding lawful basis for processing do not apply. All data processing occurs locally on your device under your direct control.

Children's Privacy

sTrain does not knowingly collect any information from anyone, including children under the age of 13 (or applicable age in your jurisdiction). Since no data is collected or transmitted, the app can be safely used by all age groups under appropriate supervision.
