Privacy Policy

Last updated: October 2026

1. Information We Collect

When you use ReplayGlows, we collect information you provide directly to us, including:

  • Account information (name, email address) when you sign up
  • Notes and timestamps you create while watching videos
  • Study cards you create and their review history (grades and next review dates)
  • AI provider API keys you choose to add (OpenRouter or Cerebras), stored encrypted
  • Video URLs you add to your library
  • Preferences and settings you configure

2. How We Use Your Information

We use the information we collect to:

  • Provide, maintain, and improve our services
  • Make your notes available in the web app wherever you sign in
  • Send you technical notices and support messages
  • Respond to your comments and questions
  • Send you ReplayGlows product updates by email, if you subscribe to the newsletter

3. Newsletter

If you subscribe to the ReplayGlows newsletter, we collect your email address only with your consent. We then send a confirmation email, and your subscription is active only once you confirm it by clicking the link in that email (double opt-in).

We use your email address only to send ReplayGlows product updates. Every email includes an unsubscribe link. Emails are sent via Postmark.

4. YouTube API Services

ReplayGlows uses the YouTube API Services to display video content. By using our service, you are also agreeing to be bound by the YouTube Terms of Service and Google Privacy Policy.

5. Service Providers

We use the following service providers to run ReplayGlows:

  • Clerk: authentication and sign-in to your account
  • Convex: database storing your account data
  • Vercel: hosting of the web application and the website
  • Postmark: sending newsletter emails, if you subscribe
  • The AI provider you choose (OpenRouter or Cerebras): receives the transcript text needed when you request an AI feature, using the key you saved
  • Google (YouTube API Services): provision of YouTube video content

6. Data Security

We implement appropriate technical and organizational measures to protect your personal information against unauthorized access, alteration, disclosure, or destruction. Data travels between your browser and our services over encrypted HTTPS connections, AI provider keys you add are stored encrypted, and your notes and study cards are only accessible from your account. When you ask for an AI summary or an AI study card draft, only the transcript text needed for that request is sent to the provider whose key you saved; nothing is sent without your explicit request.

7. Data Retention

We retain your information for as long as your account is active or as needed to provide you services. You can delete your account and associated data at any time through your account settings.

8. Your Rights

You have the right to access, correct, or delete your personal information. You can export your notes as Markdown or JSON from the browser extension; notes and bookmarks saved by the extension stay stored locally in your browser. Exporting your notes from the web app is part of the Pro plan, which is not yet available. On request, we provide a copy of your account data.
