Privacy Policy

1. Data we handle

• Account and profile data, such as your email address, authentication provider, username, display name, profile image, preferences and subscription status.
• Activity data, such as walk or run type, route points, precise location while recording, timestamps, distance, duration, pace, estimated energy and activity history.
• Community data you choose to create or share, including friendships, club membership and requests, messages, events, challenges, leaderboards, reactions, shared activities and music or playlist details.
• Technical and service data, such as app version, device and operating-system information, push-notification tokens, crash reports, diagnostics, feature events and support correspondence.
• Website data, including language and cookie choices, optional Vercel and Google Analytics data after consent, and the email and language preference you provide if you join a waitlist or mailing list.

2. Location, routes and territory features

Yukan uses location to record an activity, draw a route, calculate movement statistics, support eligible closed-route territory features and provide location-relevant experiences. Foreground recording uses the permission you grant in iOS. Background recording or movement detection requires separate settings and permissions and may be limited by iOS, signal quality, device state and battery conditions.

A route or territory can reveal where you live, work or spend time. Review the audience and map before sharing. Yukan may offer privacy controls or route masking, but no masking method can remove every inference from a route.

3. Apple Health and fitness data

If you explicitly connect Apple Health, Yukan may request read access to steps, walking and running distance, workouts, heart rate, resting heart rate, active energy, body mass, height, date of birth and biological sex. Yukan may request permission to write workouts, workout routes, walking and running distance and active energy to Apple Health.

Yukan uses information obtained through HealthKit only to provide health and fitness functionality. It is not used for advertising or sold to data brokers. Apple controls Health permissions, and you can review or revoke them in iOS or the Health app. Health data already written to the Health app is controlled there and is not removed by deleting your Yukan account.

4. Optional music, Screen Time and notification features

If you connect Apple Music or enable music sharing, Yukan may read current or recently played track metadata and store selected now-playing or run-playlist details so the feature can work with the audience you choose. You can disconnect the feature or clear shared now-playing information in the app where available.

If you enable movement-based Screen Time rules, Apple frameworks provide authorization and enforcement. App and category selections and rule state are handled on your device and may be shared with Yukan app extensions on that device; related settings or earned-time records may be associated with your Yukan account. Yukan does not guarantee that iOS will enforce or refresh a rule at an exact moment.

If you enable notifications, Yukan and its notification providers process a device token and delivery-related data. Notification delivery is controlled partly by Apple and device settings and is not guaranteed.

5. How we use data

Depending on the feature and applicable law, processing may be necessary to provide the service you request, based on your consent, necessary for legitimate service and security interests, or required by law. You may withdraw consent for future processing where consent is the basis, although this does not undo processing already lawfully carried out.

• Provide, secure and troubleshoot accounts, activity recording, history, maps, territory features, clubs, sharing and optional integrations.
• Calculate and display activity statistics, progress, challenges and other features you request.
• Maintain community safety, investigate abuse, enforce these Terms and protect the service and its users.
• Send transactional messages, respond to support or privacy requests and, where permitted, send waitlist or product communications that you can unsubscribe from.
• Understand reliability and feature use through diagnostics and analytics, and improve Yukan.
• Meet legal obligations and establish, exercise or defend legal claims.

6. When data is shared

Information is visible to other people when you choose a public, friends, club or other community audience, join a shared feature, post content, or export a share card. Club administrators may see membership requests and information needed to manage a club.

Yukan relies on service providers and platform partners to operate the product. These may include Supabase for authentication, database, storage and synchronization; Firebase for analytics, crash reporting and notifications; Apple for App Store, Health, Music, Screen Time, maps, weather and device services; Vercel for website hosting and analytics; Google Analytics when website consent is given; and Resend or similar email infrastructure for requested or subscribed email.

Data may also be disclosed when required by law, to protect rights or safety, in a business reorganization subject to appropriate protections, or at your direction. Providers may process data in countries different from yours. You can contact privacy@smeanalytica.dev to ask about transfers and safeguards relevant to your data.

7. Retention and account deletion

Data is kept for as long as needed to provide the account and features you use, maintain security and integrity, meet legal obligations, resolve disputes and enforce agreements. Different records can have different retention needs; Yukan does not promise a single fixed period for every category.

The current in-app deletion flow marks the profile as deleted, signs the account out, and removes certain active or social records such as current music status, pending friend requests and friendships. Some run, territory and challenge records may remain in restricted historical records to preserve service integrity. You can contact privacy@smeanalytica.dev to ask for review of retained personal data and any further action available under applicable law.

Where backup copies or provider logs exist, they follow separate provider and operational retention processes and may not be removed at the same moment as active records. Data may be retained where law or the establishment, exercise or defence of legal claims requires it.

8. Your choices and rights

We may need to verify your identity before acting on a request. Some rights are subject to legal conditions and exceptions. Contact privacy@smeanalytica.dev for privacy requests.

• Change app visibility and sharing settings before publishing or sharing content.
• Change Location, Health, Music, Screen Time and notification permissions in the app or Apple system settings.
• Decline optional website analytics or change your choice using Cookie preferences in the footer and unsubscribe from waitlist or product email using the link provided.
• Request access, correction, deletion, restriction, portability or objection where applicable, and withdraw consent for future processing where consent applies.
• Complain to your local data-protection authority where that right applies.

• Email the privacy team

9. Security and changes

Yukan uses technical and organizational measures intended to protect personal data. No internet, cloud or device system is completely secure, so absolute security cannot be guaranteed.

This policy may change as the product, providers or law change. The updated date will be shown here. If a change materially affects how data is handled, Yukan will provide additional notice where required.
