At Deckr, we take your privacy seriously. This Privacy Policy explains what information we collect, how we use it, and your rights regarding your data.

We use your information to:

  • Generate flashcards and quizzes from your notes using AI

When you generate flashcards, your notes are sent to Anthropic's Claude API for processing. Anthropic processes this data to generate your flashcards.
