Publisher (Contracting Entity): Kago Studio (a sole proprietorship trade name, lawfully operated by its proprietor who is authorized to execute and perform these Terms)
Product Name: LightLog
Effective Date: May 19, 2026
Welcome to LightLog. Please read these LightLog Terms of Use (the “Terms”) carefully before using the Service. By downloading, installing, accessing, or using LightLog, you acknowledge that you have read and agree to be bound by these Terms. If you do not agree to any part of these Terms, please stop using LightLog.
These Terms incorporate and supplement Apple’s standard Licensed Application End User License Agreement (EULA). If there is any conflict between these Terms and the Apple EULA, the stricter requirement permitted by applicable law shall prevail.
For the avoidance of doubt: the display name of the App Store developer account is used for platform distribution and display purposes only and does not by itself change the contracting-entity designation under these Terms; rights and obligations related to LightLog are borne by the publisher (contracting entity) identified above.
