SmartHIIT Privacy Policy

What Stays on Your Device

• SmartHIIT does not ask for your name, email address or any login.
• Your timer settings, routines, training plan, workout history, effort feedback and fitness check results are stored on your iPhone. We do not receive them.
• If you back up your iPhone with iCloud or a computer, Apple includes this data in your backup under your Apple Account.
• Workout reminders are scheduled on the device. They are not sent from a server.

Anonymous Usage Data

• The app records which features are used, such as starting or finishing a workout, opening the subscription screen or creating a plan. We use these counts to understand what works and to improve the app.
• These events are sent to Google Analytics for Firebase with a random identifier created for the app installation. They carry no name, email address, exercise names, health data or free text.
• Google Analytics also receives general technical information, such as device model, iOS version, app version, language and approximate country.
• This data is not used to show you ads and is not linked to your identity.
• You can switch it off at any time in the app: Settings > Privacy & Tracking > Anonymous usage data.
• Google keeps this data for the retention period set in our Analytics account, which is 14 months at most.

Tracking for Advertising

• SmartHIIT only uses tracking if you allow it in the iOS tracking permission prompt, which the app shows only when you ask for it in its Settings.
• If you allow it, the Meta (Facebook) SDK receives your device's advertising identifier and app activity such as installs and app launches, so that we can measure our own advertising.
• If you do not allow it, none of this is sent. You can change your choice in iPhone Settings > Privacy & Security > Tracking.

AI Workout Generator

• When you ask the app to create a workout or exercises with AI, it sends the choices for that request: goal, fitness level, focus areas, equipment, duration, language, energy and impact preferences, any notes you type, and the names of exercises and routines in your library, including the ones you used recently or marked as favorites.
• The request is processed by our server function hosted on DigitalOcean and by the AI model provider xAI, and the answer comes back to your device. It carries no name, email address or account.
• We do not keep a database of these requests. The hosting and AI providers may keep technical logs for a limited time under their own policies.
• Please do not type personal or medical details in the notes field.

Apple Health

• Connecting Apple Health is optional. If you turn it on, SmartHIIT saves your finished workouts and their estimated active energy to Health, and reads your weight only to make that estimate.
• Health data stays on your device and in Apple Health. It is never sent to us, to analytics or to advertising services.

Subscriptions

• Purchases are handled by Apple. We never see your name, payment card or Apple Account.
• The app learns from Apple whether a subscription is active, and records anonymous purchase events (product, price, currency and transaction number) with the usage data described above.

Service Providers

• Apple: App Store, subscriptions, Apple Health and iCloud backup.
• Google (Firebase Analytics): anonymous usage data.
• Meta (Facebook SDK): advertising measurement, only with your tracking permission.
• DigitalOcean and xAI: AI workout generation.

These providers may process data in the United States and other countries, under their own privacy policies.

Your Choices and Rights

• Switch off anonymous usage data in the app's Settings.
• Allow or deny tracking in iPhone Settings.
• Turn Apple Health and reminders on or off in the app's Settings.
• Delete the app to remove everything it stored on your device.
• Depending on where you live, you may have the right to access, correct, delete or object to the processing of your personal data. Because the app has no account and the usage data is not linked to your identity, we usually cannot find the data of a specific person, but write to us and we will help.
• Where the law asks for a legal basis: advertising tracking happens only with your consent, and anonymous usage measurement relies on our legitimate interest in improving the app, with the option to switch it off.

Children

SmartHIIT is not directed to children under 13, and we do not knowingly collect personal information from them.

Changes to This Policy

If the app starts to handle information differently, we will update this page and its date before the change reaches the App Store.
