Privacy Policy

With your permission, Stackhero can read selected Apple HealthKit metrics such as sleep, HRV, resting heart rate, VO2 max, active energy, and workouts.

If you create an account, we collect account details such as email, authentication identifiers, optional display name, supplements, schedules, adherence logs, and app usage events.

Analytics and subscription services may process diagnostic events, feature usage, paywall events, purchase status, and attribution data. Analytics events do not include HealthKit samples, supplement names, or dosage details.

We use your information to provide supplement tracking, schedules, reminders, account sync, interaction checks, AI-assisted insights, subscription access, diagnostics, and product improvement.

HealthKit data is used only for app functionality. We do not sell HealthKit data, use it for advertising, or share it with data brokers.

Stackhero uses Supabase for backend hosting and authentication. Data is transmitted over HTTPS/TLS, and account-linked database access is protected with row-level security.

HealthKit samples stay on your device for local charts. Aggregate metric snapshots may be sent to Stackhero servers only when needed for Pro AI insight features.

We may use providers including Supabase, Amplitude, AppsFlyer, Adapty, OpenRouter, Google Gemini, PubMed/NCBI, Semantic Scholar, Exa, and Consensus to operate app features.

These providers process data only as needed to provide app functionality, analytics, attribution, subscriptions, research lookup, or AI features.

You can revoke HealthKit, camera, and notification permissions in iOS Settings.

You can delete your account and account-linked app data from Stackhero settings where available, or contact us for help.

Stackhero is not intended for children under 13, and we do not knowingly collect personal information from children.

Stackhero is operated by Space Cadet d.o.o., Ulica Ivana Šibla 17, 10000 Zagreb, Croatia.
