Privacy Policy
Effective: April 28, 2026 | Last updated: April 28, 2026
This is an English translation. In case of any conflict, the Korean version at
wyr.kr/ko/privacy prevails.
WYR (the "Service") values the privacy of its users and complies with applicable laws including the Personal Information Protection Act of Korea.
This policy describes the categories of personal information we collect, the purposes of use, retention periods, third-party sharing, and user rights.

2. Purposes of Use
- Storing running records and providing statistics
- Course-based runner matching (discovering runners on the same course)
- Encounter matching (post-run GPS record comparison)
- Providing social features such as Signals and Greet
- Service improvement and error analysis
3. Location Data Processing Principles
WYR is designed with privacy as the top priority.
- Exact real-time location is never shared with other users.
- Encounter matching is performed through post-run analysis only.
- Matching calculations use privacy-masked and downsampled data.
- Exact times are not disclosed; only time-of-day buckets (morning/evening, etc.) are shown.
- Presence alerts are provided in 500m radius segments only.
4. Progressive Information Disclosure
Information visible to other users is determined progressively based on course level and encounter count.
- Profile data (photo, nickname, Instagram) is only shown when the user has explicitly opted in.
- A Greet (greeting) requires mutual consent from both sides to establish a relationship.
5. Retention and Deletion
- All personal information is deleted without delay upon account deletion.
- Running records, encounter history, and profile information are all removed.
- Data required by law to be retained is kept only for the legally mandated period.
6. Third-Party Sharing
WYR does not provide personal information to third parties without user consent.
Exceptions are limited to the following cases:
- When required by law
- When the user has given prior consent
