Privacy policy
Effective September 15, 2026 · Applies to the 5km iOS app and support website
5km is a running tracker that works without an account. Running records are processed and stored on your device and are not sent to a server operated by the developer.
1. Operator and contact
Operator and privacy contact: Seungchul Lee (이승철)
Email: codinglee@codinglee.com
2. Information used by the app
- Location and running records: GPS location, route, distance, time, pace, and elevation provide your running record and analysis.
- Motion: Device motion features measure cadence in steps per minute.
- Optional profile: Your nickname and weight are stored on your device for display and calorie estimates. They are not used to create an account.
- Photos: Photos you take or select are used to create running photo cards on your device.
- Settings: Target distance, voice guidance, metronome, and other preferences are stored on your device.
This information is not collected or retained on the developer’s server. The app does not include advertising or an analytics SDK for tracking user behavior.
3. Permissions and background activity
Location access records distance and route. Motion access measures cadence. Camera and photo access support optional running photo cards. Background location and audio allow recording and guidance to continue during an active run when the screen is locked.
You can change these permissions in iOS Settings at any time. Declining a permission limits the related feature.
4. External services and sharing
Apple system features, such as map display, may communicate with Apple to provide their services. Their data handling follows Apple’s privacy policy and your device settings.
When you choose another app in the share sheet, the content you select is passed to that app. Its own privacy policy applies. 5km does not automatically publish running records or photos.
The operator does not sell your running records or provide them to third parties for advertising.
5. Retention and deletion
Running records and settings remain on your device until you delete them or remove the app. Choose Delete run on a run’s detail screen to remove that record. Copies saved in Photos or shared to another app must be deleted separately from those locations.
Data included in device backups is managed by iOS and your backup settings. The operator cannot remotely access, change, delete, or restore records stored on your device.
6. Support email and website
If you contact us by email, your reply address, message, and any attachments you choose to send are used to respond to your inquiry. You do not need to include unnecessary location records or sensitive information. Support materials are retained for as long as needed to handle the inquiry and deleted on request unless there is a legitimate reason, such as a legal retention requirement, to keep them.
The support and privacy pages do not contain advertising, analytics scripts, or contact forms. The hosting service may process technical information, such as IP address, access time, and browser details, to deliver and secure the website.
7. Your choices and requests
You can manage your local records and optional profile in the app and withdraw permissions in device settings. Email the contact above to request access, correction, or deletion of support information held by the operator, or to ask a privacy question.
8. Policy changes
We will update this page and its effective date when app features or data handling change. Material privacy changes will be announced in the app or on this page.
