What this notice covers

This notice describes the Kettlebell Counter mobile app and this informational website.

Information stored in the app

The app stores working data on your device using local app storage. Depending on your choices, this can include language and onboarding choices; training preferences such as exercise, target, sets, weight, sound, and music settings; workout records and set details; saved plans; reminders; achievements; and profile settings you enter. Workout details can include dates and times, target and actual reps, duration, weight, notes, and perceived effort.

Feedback and support

When you choose to send feedback through the in-app FeedbackHub page, you provide the feedback category and message. You may also choose to attach screenshots or provide contact information. To help us investigate, the app may send the app version, build number, platform, locale, and the screen name where you opened feedback. Ordinary training records stay in local app storage and are not attached to feedback automatically.

FeedbackHub does not require an account. It stores feedback in Shanghai, China. A separate anonymous access token for each feedback item is kept in the FeedbackHub WebView’s persistent local storage so you can reopen your feedback, see a developer reply, or delete that feedback. The form includes a public-wall setting; review it before submitting and turn it off if you do not want the feedback published. Feedback is shown on the public wall only when that setting is enabled at submission. FeedbackHub does not use advertising tracking.

Premium and purchases

Versions offering Premium use RevenueCat and Apple App Store or Google Play for purchases and restoration. RevenueCat uses an anonymous app user identifier and necessary product, transaction, purchase-history and entitlement information to verify access. The store handles payment details. We do not send exercises, weights, reps, workout history or heart rate to RevenueCat. See the RevenueCat privacy policy for its practices.

The used count for the first five valid workouts is stored locally; deleting workout history does not reset it. Clearing local data does not cancel a store purchase. The store and RevenueCat retain purchase-related data under their policies; contact support if you need help. Purchasing, restoring and necessary entitlement verification require internet access.

How data is used

Local data shows your training setup and history, retains preferences, runs local reminders you configure, and creates the exports or share cards you choose. The app does not provide workout accounts or workout cloud sync, and does not use workout data for analytics or advertising. Purchase verification is handled under the third-party policies described here.

Sharing and exports

Sharing is voluntary. You can choose whether a result card includes training data before using your device’s share sheet. Settings can copy a JSON export of local app data or a CSV export of workout history to your clipboard. Once you paste, save, or share an export with another app or person, that recipient handles it under its own rules.

Permissions

Phone manual training does not require health permission. The current mobile version does not access Apple Health or perform health sync. When you turn on reminders, the app requests notification permission on iOS or Android. Android may also use a system capability to restore reminders you set after a device restart. You can also turn notification permission off in your device settings.

Retention, security, and deletion

Data remains in local app storage until you change or delete it, uninstall the app, or your operating system removes it. You can delete one workout from Records. Settings deletes workout history and achievements but does not erase plans, profile settings, language, or default weight. To remove all local app data, copy anything you want to keep and use operating-system app-data removal or uninstall controls. Device backups enabled by you or your operating system may also include local app data under those services’ settings. Use device lock, system updates, and trusted apps to help protect local data.

Website and third parties

This static website has no forms, tracking pixels, or marketing cookies. Cloudflare may process ordinary technical request data, such as an IP address and request logs, to deliver and secure the website under its terms and privacy notice. When you choose these features, the app uses platform services such as local notifications, audio playback, clipboard, and the device share sheet.

Changes and contact

If the app adds an account, cloud service, analytics, a new use of health data, or a new permission, we will update this notice before providing that feature. When you email feedback@uhuoban.com, we receive your email address, message, and any attachment you choose to send. We keep them only as needed to reply and handle your request. Please do not send unnecessary sensitive health materials. Use the same address for questions about this notice or privacy.
