Privacy Policy

Last updated: December 2024

1. Introduction

Welcome to Deckloop. We respect your privacy and are committed to protecting your personal data. This privacy policy explains how we collect, use, and safeguard your information when you use our service.

2. Information We Collect

2.1 Account Information

When you create an account, we collect:

  • Email address
  • Name (if provided)
  • Password (hashed)

2.2 Usage Data

We automatically collect certain information when you use our service:

  • Study sessions and review history
  • Deck creation and management activities
  • Device information and browser type
  • IP address and approximate location data (for example, based on IP)

2.3 Cookies and Analytics

We use cookies and similar technologies to improve your experience. With your consent, we use Google Analytics to understand how users interact with our service. You can change your cookie preferences at any time via Cookie Settings in the footer.

2.4 Uploaded Content

When you use features that involve uploading or importing content, we may collect and store:

  • Documents you upload for deck creation (such as PDFs or text)
  • Images and media attached to your cards
  • Import files (such as Anki decks) and any related media
  • Audio generated by text-to-speech features

2.5 AI-Generated Content

When you use AI features (such as deck generation or explanations), we may store the AI-generated results so you can access them again without reprocessing. This helps avoid repeated processing (and, where applicable, repeated AI credit usage) and improves loading times.

What we can provide as part of a "copy of your data" request typically includes: your account/profile details, a CSV export of your decks (front/back), and a summary of your learning activity (aggregated statistics similar to what you see in the app).
