These Terms are Product Terms that set out the conditions for using the beta version of the secure chat system "Kagima -鍵間-" (hereinafter, "the Service") provided by SimpleAppli Inc. (hereinafter, "we" or "us").
* The original version of these Terms is the Japanese version (https://simpleappli.com/terms_kagima), and this is a translation. Although we have prepared it carefully, if there is any difference from the original due to translation, the original Japanese Terms will apply.
1-1. These Terms are Product Terms under our Terms of Service (hereinafter, "the Common Terms") and form part of the Common Terms.
The Common Terms apply to matters not covered by these Terms, and if there is any inconsistency between these Terms and the Common Terms, these Terms prevail.
