Core30: Ab & Core Workout

Last updated: 7 November 2026

Core30 is a core and ab workout app for iPhone. It's made by SGWNI, a one-person app studio (“I”, “me”). This policy explains what information the app handles and where it goes.

In short

• Your plan, workouts, progress and settings stay on your iPhone. I never receive them.
• There's no account to make.
• If you allow it, finished workouts are saved to Apple Health.
• The app counts how it's used, anonymously, with TelemetryDeck.
• Core30 Pro is sold through the App Store, and RevenueCat checks whether you have it.
• There's no advertising, no tracking across other apps or websites, and nothing is sold or shared.

On your iPhone

Your goal and level, your 30-day plan, the workouts you build, your finished workouts, streaks and settings are stored in the app on your iPhone. They're included in your iPhone's backups like any other app's data, and deleted when you delete the app. Workout reminders are notifications scheduled on your iPhone, not sent from a server.

Apple Health

If you allow it, Core30 saves each finished workout to Apple Health, with its duration and estimated active energy. Core30 only writes to Apple Health; it doesn't read your Health data. Health data is never sent to me or anyone else, and is never used for advertising. You can change this in the Health app under your profile › Apps › Core30.

Anonymous usage statistics

Core30 uses TelemetryDeck to count how the app is used: for example, that onboarding was started or finished and the goal and level chosen, that a workout was started, finished or abandoned, that a reminder was turned on, or that the Core30 Pro screen was shown and a plan picked. Each signal also carries general details such as the app version, iOS version, type of device and language. TelemetryDeck doesn't collect names, email addresses or locations, and the identifier it uses is anonymised before it leaves your iPhone.

Subscriptions

Core30 Pro is an auto-renewing subscription sold through the App Store. Apple handles payment, so I never see your payment details, name or Apple Account. The app uses RevenueCat to check whether you have Core30 Pro: RevenueCat receives your App Store purchase receipt, basic device information and a random identifier created by the app.

Keeping and deleting your information

Your workouts stay on your iPhone until you delete them or the app. Workouts saved to Apple Health stay there until you delete them in the Health app. Manage or cancel your subscription in your App Store account settings.

Your rights

Depending on where you live, including under the UK and EU General Data Protection Regulation, you have the right to ask what information is held about you, to have it corrected or deleted, and to object to how it's used. Your workouts never leave your iPhone, so I hold none of them. I use the anonymous statistics because it's in my legitimate interest to understand how the app is used and improve it; TelemetryDeck processes them on my behalf. Requests about App Store purchases go to Apple, which holds them.

Children

Core30 isn't directed at children under 13 and doesn't knowingly collect personal information from anyone, including children.
