Yes. Your materials are encrypted in transit (TLS 1.3) and at rest (AES-256). We never train AI models on your content, and document embeddings are generated on our own infrastructure — your study data belongs to you.

Learnzo uses the SM-2 algorithm, the same proven system used by Anki and SuperMemo. Each review schedules the next one at the optimal interval based on how well you remember the card, which maximizes long-term retention.

Learnzo is credit-based. Every plan includes a monthly credit allowance, and each AI generation consumes a small number of credits (for example, one flashcard or quiz question costs one credit). The Free plan includes 100 credits a month — enough to try everything.

Yes. Workspaces let you invite members with role-based permissions to share notes, flashcards, quizzes, and collections — useful for study groups, classrooms, and teams.
