Article 1 (Purpose)
These Terms set out the basic matters — the rights, obligations and responsibilities between SyncRun Labs (the "Company") and members, and the conditions and procedures for use — in connection with the use of the iOS and Android running application SyncRun and all related services (the "Service").

"Member" means a person who agrees to these Terms, enters into a service agreement with the Company, and uses the Service.
3.
"Account" means the information the Company assigns for identifying a member and enabling use of the Service (Apple sign-in identifier or Google sign-in identifier, user ID and the like).

"Bump" means the act of tapping phones together with another user so that a group to run with is formed through proximity determination using near-field wireless communication (UWB).
6.
"Running session" or "session" means the unit in which a group formed through a bump runs together.
7.
"Run card" means the image-format output that the Service generates from a run record a member has completed.

Terms not defined here follow the relevant laws and general commercial practice.
Article 3 (Publication and Amendment of These Terms)
1.
The Company publishes these Terms on the terms viewing screen in the Me tab of the app and at an internet address designated by the Company, so that members can readily review them.
2.
The Company may amend these Terms to the extent that doing so does not violate the Act on the Regulation of Terms and Conditions, the Act on Promotion of Information and Communications Network Utilization and Information Protection, and other relevant laws.
3.
Where the Company amends these Terms, it announces the amendment together with the current Terms, stating the effective date and the reasons, through the in-app notices, from seven days before the effective date. Where the amendment is unfavourable to members, it announces the amendment from 30 days before the effective date and gives separate notice by electronic means such as in-app notifications.
4.
Where the Company, in announcing amended Terms under paragraph 3, has clearly stated that failure to express refusal by the effective date will be treated as consent, and a member does not expressly refuse, that member is deemed to have consented to the amended Terms.

Where a member does not consent to the amended Terms, the member may terminate the service agreement (withdraw membership).
6.
Matters not specified in these Terms follow the relevant laws and commercial practice.

An account signed in with Apple and an account signed in with Google are separate accounts and are not linked into one, even where the email address is the same. No path is provided for signing up or signing in with an email address and password, and accordingly there is no procedure for setting or resetting a password.

Server backup of run records and synchronisation to the member's other devices

A run card for a group run may include the names, profile photos and records of other participants who ran together. Where a member shares such a run card outside the Service, the member must take care not to infringe the rights of other participants, and the member who shared it is responsible for any dispute arising.
3.
For the protection of personal information, run cards by default display only the route line without a map background and label the place only at the neighbourhood (dong) level; these protective defaults cannot be lowered.
Article 17 (Management of Postings)
1.
Where a member's posting violates relevant laws or contains content infringing another person's rights, the rights holder may request suspension of publication and deletion of that posting in accordance with the procedures prescribed by relevant laws, and the Company takes measures in accordance with those laws.
2.
Even without a request from a rights holder, the Company may take temporary measures in respect of a posting in accordance with relevant laws where there are grounds to recognise an infringement of rights or where the posting violates relevant laws.
Article 18 (The Company's Rights in the Service)
1.
Intellectual property rights in the Service itself — the software, design, trademarks, service name, logo, and the design templates of run cards generated by the Service — belong to the Company.

Members must not use, for profit, or allow third parties to use, information obtained through use of the Service in which intellectual property rights belong to the Company, by means of reproduction, transmission, publication, distribution, broadcasting or otherwise, without the Company's prior approval.

3.
Run records deleted through withdrawal of membership cannot be recovered. Members must save in advance any records they wish to keep.

1.
Where a member falls under any of the following, the Company may, after prior notice, terminate the service agreement or restrict use of the Service for a specified period.
