AI-Generated Content
AI features in Cognito use Google's Gemini (and DeepSeek in regions where Google's AI is unavailable) to generate flashcards, quiz options, explanations, and answer evaluations. Important notices:
- AI-generated content may contain inaccuracies or errors
- You are responsible for reviewing and verifying all AI-generated material
- AI content should not be relied upon for medical, legal, financial, or safety-critical decisions
- Free users can save up to 3 AI-generated batches per day; Premium users have unlimited access
No Account Required
Cognito has no sign-up, login, or user profiles. The App automatically uses an anonymous Firebase identifier in the background for analytics and crash reporting only — you are never asked to create an account or sign in.
You have full access to all features, including flashcard creation, study, and AI tools, without any account. You can erase all app data at any time from the App settings.
User Content
You retain ownership of all flashcards and study materials you create. When importing content from external sources (Anki decks, CSV files), you are responsible for ensuring you have the right to use that content.
Content you submit to AI features (topics, images, card text) is processed by our AI providers (Google Gemini, or DeepSeek in regions where Google's AI is unavailable) according to their terms. We do not store or access your flashcard content on our servers.
Privacy
Your flashcards and study data are stored on your device (and in your private iCloud, if enabled). We collect anonymous analytics and crash reports to improve the App. See our Privacy Policy for full details.
Intellectual Property
The App, its design, code, and branding are the intellectual property of the developer. You are granted a limited, non-exclusive, non-transferable license to use the App for personal purposes in accordance with these Terms.
Limitation of Liability
The App is provided "as is" without warranties of any kind. We make no guarantees about the accuracy, reliability, or completeness of AI-generated content. To the maximum extent permitted by law, we shall not be liable for any indirect, incidental, or consequential damages arising from your use of the App.
Termination
We reserve the right to restrict or terminate your access to the App if you violate these Terms. You may stop using the App at any time by deleting it from your device.
Changes to These Terms
We may update these Terms from time to time. Changes will be reflected with an updated date at the top of this page. Continued use of the App after changes constitutes acceptance of the updated Terms.
