StudyLang JA⇄EN ("we", "our") is a language-education brand operated by Eidendo. This policy explains how we handle data when we use the TikTok, Instagram, and YouTube APIs to publish our own educational videos to our own accounts.
Our application uses platform APIs solely to upload and publish video content we created to social accounts we own and operate. We request only the minimum scopes required to publish content and read the basic profile of the connected account.
We do not collect, store, sell, or share any personal data of viewers or third parties. We store only: (1) OAuth access tokens for our own accounts, kept in private server-side configuration and never exposed publicly; (2) the IDs of videos we have published, to avoid duplicate posting.
We do not access followers' data, direct messages, comments of other users, or any viewer analytics beyond the aggregate figures the platform shows the account owner.
We do not share data with third parties. Tokens are used only to communicate directly with the official platform APIs (TikTok, Meta/Instagram, Google/YouTube).
Tokens are retained only while the automation is active and are deleted on request. To request deletion of any stored data, contact us below.
