Privacy Policy

HydroFit Quest uses only the information needed to personalize hydration guidance, run app features, and respond to support requests. We do not sell personal information or use advertising identifiers.

Information we process

• Profile and wellness information: age, weight, optional gender choice, water intake, hydration goals, workouts, streaks, rewards, and league activity.
• Account information: email address, display name, authentication identifiers, policy acknowledgements, and account status when you choose cloud sync.
• Approximate location: used with permission to retrieve local weather and timezone. Exact coordinates are not stored in the app profile or sent to the AI Coach.
• AI Coach information: your question and a limited summary of your profile, hydration, workout, weather, and local-time context are sent securely to OpenAI to generate a response.
• Notification information: notification preferences, a device installation identifier, push subscription details, and a limited hydration snapshot used to schedule relevant reminders.
• Support information: email address, request category, message, and request reference when you contact support or request deletion.

How information is used

We use information to calculate adaptive goals, display progress, deliver requested AI guidance, operate private leagues, schedule notifications, prevent misuse, provide support, and improve reliability. AI Coach output is general wellness guidance and is not medical advice.

Storage and service providers

Guest progress stays on your device. If you create an account, selected profile, hydration, workout, progress, and private-league data are stored in HydroFit's EU-hosted Supabase project so they can sync across devices. Support and notification records are processed using Cloudflare services. AI Coach requests are processed by OpenAI with API response storage disabled; limited provider retention may still apply for security and abuse prevention under the provider's terms.

Your choices

You can use core tracking without location, AI Coach, push notifications, or a cloud account. You can disable location and notifications in device settings. Use the in-app Erase local app data control to remove device data, or submit an account and cloud-data deletion request through our deletion page.

Children under 16

Users under 16 may use local guest features or create a cloud account after confirming parent or guardian permission during signup. HydroFit will add a verified-consent process before public launch wherever applicable law requires one. Under-16 accounts remain private and league members do not see age, weight, gender, email, or exact location.

Retention and security

Device data remains until you erase it or uninstall the app. Cloud account data remains while the account is active and is removed after a verified deletion request, subject to backup expiry and limited records that must be retained for security or legal obligations. Open support requests are retained while needed to respond and resolve the issue, then removed or de-identified under the final retention schedule. We use access controls, encryption in transit, and limited-purpose data handling, but no online system can guarantee absolute security.

Requests and updates

Use the Support page for privacy questions or the account deletion page to request deletion. We will post material policy updates here and change the effective date.
