How is my daily target calculated?
HYDROX uses the ACSM (American College of Sports Medicine) protocol: your body weight determines your baseline hydration needs. Training mode adjustments use the Galpin equation for exercise intensity.
Does the app sync with Apple Health?
Yes. If you enable HealthKit integration, HYDROX reads and writes water intake data to Apple Health. This is optional and happens entirely on your device.
Is my data private?
Yes. All data stays on your device (and iCloud if enabled). We don't have servers. We can't see your hydration data. See our Privacy Policy for details.
How do I delete my data?
Delete the app, delete your data. Since everything is stored locally, there's nothing for us to delete on our end.
