How We Use Your Information
All data collected is used solely for App functionality purposes:

Data Storage and Sync
Your session data is stored locally on your device and synced to our cloud service when you are signed in. This allows you to access your data across devices. You may use the App without an account, in which case data remains only on your device.

These services have their own privacy policies governing their use of your data.
Data Sharing
We do not sell, trade, or share your personal information with third parties for marketing purposes. Your data is only shared when:
- You explicitly choose to share session summaries
- Required to provide the App's core functionality (e.g., cloud sync)
- Required by law
Data Tracking
ColdPlunge does not track you across other apps or websites. We do not use your data for advertising purposes.
Your Rights
You have the right to:
- Access your personal data stored in the App
- Delete your account and associated data
- Revoke health data permissions at any time through iOS Settings
- Use the App without creating an account
Data Security
We implement appropriate technical and organizational measures to protect your personal information. However, no method of electronic storage or transmission is 100% secure.
Children's Privacy
The App is not intended for users under 18 years of age. We do not knowingly collect information from children under 18.
