Privacy Policy — Nebulearn
This Privacy Policy explains how Nebulearn (nebulearn.app) collects, uses, and protects your personal information and study data. We are committed to GDPR-compliant privacy practices. Last updated January 2026.
Data We Collect
- Account information: email address, username, and password (stored as a secure hash — never in plain text)
- Study data: flashcards you create, AI-generated content, question sets, folder structure, and study session results
- Usage analytics: page views, feature usage, and performance metrics via Google Analytics (anonymised)
- Payment information: processed securely by Stripe — Nebulearn never stores full card details
- Chrome Extension data: text you highlight to generate flashcards, processed locally and transmitted only when you create a card
How We Use Your Data
- To provide the Nebulearn service including AI generation and spaced repetition scheduling
- To personalise your FSRS spaced repetition curve based on your study history
- To send account-related emails: email verification, password reset, and billing receipts
- To improve Nebulearn's AI models and product features using aggregate, anonymised data
Data Sharing
We do not sell your personal data. We share data only with service providers necessary to operate Nebulearn (hosting, payment processing, analytics) under strict data processing agreements. Study content you choose to share publicly is visible to other Nebulearn users.
Your Rights
You may request access to, correction of, or deletion of your personal data at any time. Contact us to exercise these rights. You may also delete your account from your settings page, which queues removal of all associated data within 30 days. EU and UK residents have additional rights under GDPR and UK GDPR.
Cookies
Nebulearn uses essential cookies for authentication and session management, and analytics cookies via Google Analytics (with IP anonymisation enabled). You can opt out of analytics cookies via your browser settings.
