6. Data Security

We implement industry-standard security measures to protect your information, including encrypted data transmission (HTTPS/TLS), secure authentication, and access controls. However, no method of electronic transmission or storage is 100% secure, and we cannot guarantee absolute security.

7. Data Retention

We retain your personal information and fitness data for as long as your account is active or as needed to provide you services. You may request deletion of your account and associated data at any time through the Profile settings in the App. Upon account deletion, your data will be permanently removed within 30 days.
