Article 10 (End-to-End Encryption and Device Management)

1. The Service encrypts newly uploaded Scene videos and thumbnails on the User's device before storing them on the server.
2. Trip Location Tracking coordinates and Plan content (destination titles, times, locations, notes) are encrypted on the User's device at the time of upload, and the server stores the encrypted payload.
3. The server stores and relays encrypted media files and encrypted keys, but does not directly hold plaintext media, plaintext Location Tracking coordinates, or plaintext Plan content.

Article 11 (Restrictions on Use of the Service and Content Measures)

1. If a User violates these Terms or applicable laws, the Company may restrict use of the Service or change the status of the Account.
2. In the event of a report of rights infringement, a report of illegal information, or a lawful request from an investigative agency or court, the Company may take necessary measures such as restricting the display of, deleting, or preserving the relevant Content.
3. Due to the encryption structure, the Company may be unable to check the plaintext of all Content in advance. In that case, the Company will take necessary measures based on reports, metadata, materials submitted by Users, and requests under laws and regulations.
4. A User who objects to a restriction on use or a Content measure may raise an objection through customer support or the privacy inquiry contact point.

Article 12 (Deletion, Withdrawal, and Data Processing)

1. Users may delete Scenes they have created. When a Scene is deleted, the Scene record in the server DB and the corresponding Scene media stored in GCS are deleted.
2. A Trip owner may delete a Trip that the owner owns. After a Trip deletion request, the Trip is no longer shown in the app, and a background job on the server sequentially deletes the Trip, Scenes, media, Participants, and encryption keys.
3. Users may request deletion of their location records or use the deletion feature provided in the app. Turning off Location Tracking alone does not delete existing location records.
4. Plan items of a Trip can be deleted by the Participants of that Trip, and when the Trip is deleted, the Plan items of that Trip are deleted together. When an Account is deleted, the Plan items the User created are also deleted.
5. Users may delete their Account at any time using the in-app account withdrawal feature. Upon withdrawal, the Account status is switched immediately, login sessions are terminated, and identifying information such as email is destroyed. Afterward, a server background job sequentially deletes the Trips owned by the User (where there are no other Participants) and the Scenes, location records, encryption keys, and registered device information created by the User. A Trip that has other Participants is not deleted; ownership is automatically transferred to another Participant, and only the Scenes created by the withdrawing User are deleted. The detailed processing procedure follows Article 4 of the Privacy Policy. Inquiries about Account deletion may also be received through the in-app bug report or the privacy inquiry email.
6. If a User deletes the app, locally stored data on that device may be deleted, but the Account, Trips, Scenes, comments, likes, and location records synchronized to the server may remain until a separate deletion request is made.
7. Information necessary for statutory retention obligations, dispute response, and investigation of misuse may be retained separately for the necessary period.

Article 13 (Changes to, Suspension of, and Failures in the Service)

1. The Company may change or suspend all or part of the Service for Service improvement, security, operational needs, legal compliance, or changes in external service policies.
2. Provision of the Service may be temporarily suspended for any of the following reasons.
   • Failures of servers, databases, storage, or networks
   • Failures of external services such as cloud, map, and social login services
   • App updates, maintenance, security patches
   • Natural disasters, power outages, communication failures, and other force majeure
3. Where a Service suspension is anticipated, the Company will give prior notice to the extent possible. In the case of urgent security response or failure recovery, notice may be given afterward.
4. When offline or on an unstable network, Scenes or location records may be saved on the device first and synchronized later. If the app is deleted, or the device or storage is damaged, before synchronization, records that have not been uploaded to the server may not be recoverable.

Article 14 (External Services and Third-Party Services)

1. The Service uses external services such as Google, Apple, Kakao, Google Cloud Storage, and Mapbox.
2. The availability, failures, policy changes, personal information processing, and account suspension of external services are governed by each provider's policies.
