What Immerki is

Immerki is a personal language learning tool that lets you watch YouTube playlists, read transcripts, and create flashcards from video sentences. It is not a commercial product.

What data we collect

From Google Sign-In: Your Google account ID, email address, and display name — used solely to identify your account and isolate your data from other users.

From your activity: YouTube playlists and videos you connect to the app (playlist IDs, video IDs, titles, thumbnails); your watch progress and playback timestamps for individual videos; flashcards you create (sentence, word, language, meaning, translation, and spaced-repetition scheduling data); and language preferences you configure in the app.

YouTube access: We request read-only access to your YouTube account (youtube.readonly) to fetch your playlists and video metadata. We do not read, store, or transmit your watch history, subscriptions, or any other YouTube data beyond what you explicitly connect.

What we do not collect

• Payment information
• Analytics or advertising tracking data
• Video content — only metadata and transcripts

We do not sell or share your data with third parties.
