BuraGym Privacy Policy

Last updated: October 17, 2026

This English policy describes BuraGym version 1.3 and later, with earlier measurement methods noted below. Where versions 1.0 and 1.1 handled HealthKit differently, this is noted below.

hirofumi kurosaki ("we") provides the iOS app BuraGym (the "App"). This policy explains how information is used in the App. BuraGym records walks and other activity, offers on-device trainer suggestions, and offers an optional monthly Pro subscription. It does not display a map or record a route.

Activity, location, and health data

With your permission, the App uses Core Motion to obtain steps, walking or running distance, climbed floors, and relative altitude. With your permission, it reads steps, walking and running distance, and climbed floors from Apple HealthKit. Starting with version 1.2, the App does not write to HealthKit and does not request access to workouts. Versions 1.0 and 1.1 could, when you saved a workout, write workout information, distance, climbed floors, and active energy to HealthKit; data written by those versions remains in HealthKit until you delete it in the Health app. Version 1.2 estimated recorded ascent from HealthKit flights climbed (about 3 m per floor). Starting with version 1.3, new activity records estimate ascent using the device barometer. Gaps are supplemented using flights climbed and remain marked as partially unavailable. Daily totals use HealthKit flights climbed with an adjustment for the same recorded activity to avoid double counting. Missing data is not treated as confirmed zero. Earlier saved records retain their measurement method. The App stores workout duration, distance, steps, ascent and descent, acquired elevation, activity type, titles, notes, and trainer advice on your device. Climb and acquired elevation are in-app estimates, not geographic elevation measurements.

If you allow location access, the App sends your current coordinates to Apple WeatherKit to obtain local weather. It saves the latest weather, coordinates of the weather request, and request time on your device to avoid unnecessary requests. It does not collect location in the background, store a sequence of route coordinates, or calculate walking distance from location. You can record activity without granting location access, although local weather suggestions will be unavailable.

Trainer advice is generated by rules on your device. Workout records, HealthKit information, location, and your notes are not sent to an external generative AI service for this purpose. They are not used for advertising or marketing.

Calendar export

　Pro subscribers can choose to export a finished or saved workout to a dedicated iCloud calendar. This requires an Apple Account with iCloud Calendar enabled. The App asks for full calendar access so it can create, find, and reuse its dedicated calendar. The calendar is named BuraGym in English and the existing Japanese calendar named ぶらジム is also recognized. The App does not read, search, or delete your events. It checks calendar names, identifiers, and account types to choose the destination. Export occurs only after you tap the export action; there is no automatic or bulk export.

An exported event may contain the workout title, activity type, date and time, steps, distance, acquired elevation, average speed, and any note you saved with the workout. Location and route data are not automatically written. We do not receive calendar contents. Apple may sync the dedicated calendar through iCloud according to your Apple Account settings.

Analytics, crash reporting, app verification, and ads

The App uses Google Firebase Analytics to understand screen views, feature use, and free or Pro usage; Firebase Crashlytics to diagnose crashes; and Firebase App Check to verify the App. These services may process app-instance identifiers, device, OS, app-version, crash, and diagnostic data. The App does not send precise location, HealthKit data, steps, workout distance, climbed floors, acquired elevation, workout history, trainer text, or calendar contents as Firebase Analytics events. We do not set a custom analytics user ID derived from your name, email, advertising ID, or device ID.

If you contact support, we use the email address, message, and any device or app information you provide to respond and investigate the issue. We retain support correspondence only as needed for follow-up and remove it when no longer needed.

The free version uses Google AdMob for banner ads. Google's advertising SDK may process IP address, device or app identifiers, ad impressions and interactions, diagnostics, and performance data for ad delivery, measurement, and fraud prevention. An approximate location may be inferred from IP address. The App does not provide the precise coordinates obtained for weather, activity or HealthKit data, workout history, trainer text, or calendar contents to the ad SDK for ad targeting. The Pro version does not show ads. The App does not request App Tracking Transparency permission or access to the IDFA for cross-app tracking.

For regions where required, Google User Messaging Platform presents privacy choices before ad requests. Ad requests are permitted only when UMP reports that they can be made. Firebase Analytics consent defaults to denied until the consent status is determined. Where UMP requires a privacy-options entry, you can review or change your choices in the App's Settings. If you withdraw consent and UMP no longer permits requests, the App stops requesting ads. Firebase and AdMob may share ad impression, interaction, and revenue information because the services are linked; they do not receive the activity or calendar contents listed above for this linkage.

Google's handling of data is described in its Privacy Policy and information on partner apps. See also Firebase privacy information and Apple's Privacy Policy.

Purchases, retention, and your choices

The monthly auto-renewing BuraGym Pro subscription is billed and managed by Apple's App Store. The current period and price appear in the App and App Store. We use purchase status only to manage feature access; we do not receive or retain payment-card details.

You can delete locally saved workout records and trainer history from Settings. Uninstalling the App deletes its local data; iOS's Offload App option may retain data. Deleting App records does not automatically delete HealthKit data, exported calendar events, or information already sent to Firebase or AdMob. Manage HealthKit records in Health and exported events in Calendar. Saved weather coordinates are removed when the App is deleted. Trainer home advice older than 180 days or exceeding 1,000 entries is removed when new history is saved. Other local records remain until you delete them, subject to feature-specific limits.

You can manage location, Motion & Fitness, HealthKit, and Calendar permissions in iPhone Settings or Health. Revoking a permission does not delete previously stored or transmitted information. If a privacy-choice option is available in the App, you may change ad and analytics consent there. For requests concerning access, correction, deletion, or use of information we manage, contact us below. We respond in accordance with applicable law where we can verify the requester and identify the information.

We apply reasonable safeguards against unauthorized access, loss, or alteration. We may disclose information where required by law, with your consent, or to service providers as needed to operate the App. We do not provide HealthKit, Motion & Fitness, or calendar data to advertising providers or data brokers for advertising or marketing. The App is not primarily directed at children, and we do not intentionally collect children's names, addresses, or email addresses.

We may update this policy when the App, services, or applicable requirements change. Material changes will be announced on the website or in the App as appropriate.
