Report a bug or request a feature
Open an issue on GitHub. This is the best way to track problems and lets other users follow along:
Helpful details to include: your platform (macOS, Windows, iOS, Android), the app version (visible in the footer of the website and in the app's about screen), and steps to reproduce.

Common questions
The first launch is downloading something — what is it?
The full Bible text and pre-computed embeddings are about 670 MB. We download it once so the rest of your reading is instant and offline-capable. After that, no network is required to read.
Why does the explain feature need the internet?
Explanations are generated by an AI model running in the cloud. You can choose your provider — OpenAI or Groq with your own API key, or Marrow AI (our hosted option). Reading the Bible itself never requires an internet connection.
Can I use Marrow without an account?
Yes. Reading, search, and on-device features all work without signing in. An account is only needed for note sync across devices and for the Marrow AI provider.
How do I delete my data?
Email hello@marrowbible.com with the email address on your account. We'll delete your account, synced notes, and any usage records.
How do I cancel a subscription?
Subscriptions are managed by the platform you bought through — App Store, Google Play, or Stripe via RevenueCat. Open your platform's subscription settings to cancel; we don't have the ability to cancel on your behalf.
Security
If you've found a security issue, please don't open a public issue. Email us at security@marrowbible.com and we'll respond as quickly as we can.
