Privacy Policy
Last updated: April 26, 2026
This Privacy Policy describes how Mneva ("Mneva," "we," "us," or "our") collects, uses, stores, and shares information about you when you use our website at mneva.app, our web application, and any related services (collectively, the "Service"). By using the Service, you agree to the collection and use of information in accordance with this policy.
If you do not agree with this policy, do not use the Service.
1. WHO WE ARE
Mneva is an AI-assisted flashcard and study platform designed for students. We are operated as a sole proprietorship / limited liability company based in the United States. For questions about this policy, contact us at privacy@mneva.app.
2. INFORMATION WE COLLECT
2.1 Information You Provide Directly
Account Information
When you create an account, we collect your full name, email address, and password (stored in hashed form — we never store your plaintext password). You may optionally provide a username and customize your profile avatar.
Content You Create
We collect the content you create while using the Service, including flashcard decks, individual cards, folder names, study circle names and messages, and feature requests submitted through our support page.
Payment Information
We use Stripe to process payments. We do not collect or store your full credit card details. Stripe provides us with a customer ID and subscription status so we can manage your account.
Communications
If you contact us via email or support channels, we collect the content of your message and any attachments, along with your email address and any other information you choose to provide.
2.2 Information We Collect Automatically
Usage Data
We collect information about how you interact with the Service, including pages visited, buttons clicked, study sessions completed, cards reviewed, and game results. This helps us improve the product and understand which features are most useful.
Device and Log Data
We collect your IP address, browser type, device type, operating system, referring URLs, and the dates and times of your visits. This is standard server log data used for security, debugging, and analytics.
Cookies and Local Storage
We use cookies and browser local storage to keep you logged in, remember your preferences, store cached study data for offline access, and support analytics. You can disable cookies in your browser, but some features may not work correctly.
2.3 Information From Third Parties
If you log in using Google OAuth, we receive your Google account email address and name. If you use our browser extension or import tools, you may provide content from third-party services. We only process that content to provide the requested feature.
3. HOW WE USE YOUR INFORMATION
We use the information we collect to:
- Provide, maintain, and improve the Service
- Generate flashcards and other AI-assisted study content
- Track your progress and calculate spaced-repetition schedules
- Process payments and manage subscriptions
- Send important account updates, security alerts, and optional newsletters
- Respond to your support requests and feature suggestions
- Detect and prevent abuse, fraud, and security incidents
- Analyze usage patterns to improve product performance and usability
4. HOW WE SHARE YOUR INFORMATION
We do not sell your personal information. We only share it in the following limited circumstances:
- Service providers: We use Stripe for payments, OpenAI for AI generation, Supabase for database hosting, and Vercel for hosting. These providers only process data on our behalf and under strict confidentiality obligations.
- Legal compliance: We may disclose information if required by law, subpoena, or government request, or to protect our rights, property, or users.
- Business transfers: If Mneva is acquired or merges with another company, your information may be transferred as part of that transaction. We will notify you before any personal information is transferred under a different privacy policy.
- With your consent: We may share information when you explicitly ask us to, such as when you share a public deck or join a public study circle.
5. AI AND CONTENT PROCESSING
When you upload PDFs, paste text, provide YouTube links, or record voice memos, we send that content to OpenAI for processing into flashcards. Please do not upload sensitive personal information (such as Social Security numbers, medical records, or financial documents) unless you have the right to share it and accept the associated risk. We retain uploaded content only as long as necessary to provide the Service and support your account.
6. DATA SECURITY
We use industry-standard measures to protect your data, including hashed passwords, encrypted database connections, HTTPS for all traffic, and row-level security policies in Supabase. No system is perfectly secure, and we cannot guarantee absolute security. If you discover a vulnerability, please contact us at security@mneva.app.
7. YOUR RIGHTS AND CHOICES
Access and update: You can update your profile, decks, and settings from within the app.
Delete your account: You can request account deletion in your settings. We will delete your personal data within 30 days, except where retention is required for legal or security purposes.
Export your data: You can export your flashcard decks from your account settings.
Email preferences: You can opt out of non-essential emails in your notification settings.
Cookies: You can manage cookies through your browser settings.
8. CHILDREN'S PRIVACY
The Service is intended for users 13 years of age or older, or 16+ where required by law. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, contact us and we will delete it.
9. CHANGES TO THIS POLICY
We may update this Privacy Policy from time to time. When we make material changes, we will notify you by email or through the Service. The updated policy will be posted on this page with a revised "Last updated" date.
