Support
We read every message.
Marrow is built by a small team. The fastest way to get help is one of the channels below — pick whichever is most comfortable.
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.
Email us
If you'd rather not use GitHub, or your message is private (account, billing, account deletion):
Delete your Marrow account and data
You can delete your account in the Marrow app from Settings → Delete account (update to the latest version first). You can also email privacy@marrowbible.com from the email address associated with your account and use the subject “Delete my Marrow account.” If you cannot email from that address, explain that in your message so we can verify ownership another way.
After verification, we aim to complete the request within 30 days. Account deletion removes your Marrow account and the synced notes, sign-in records, AI usage records, and subscription mappings associated with it. Deleting your account, in the app or by email request, immediately cancels any subscription you bought in the Marrow desktop app, with no refund for unused time. Deleting in the app also removes your notes from that device. Copies on your other devices are no longer shown or synced, but stay stored there until you uninstall Marrow or clear its data. Deletion does not cancel an App Store or Google Play subscription; cancel those in the store. Some providers or legally required records may be retained as explained in our Privacy Policy.
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 use OpenAI with your own API key or Marrow AI, our hosted option. Both currently use OpenAI's API. 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 cancel a subscription?
App Store and Google Play subscriptions are managed by Apple and Google. Open your store's subscription settings to cancel. For a subscription bought in the Marrow desktop app, email support and we'll cancel it for you, or delete your account in the app to cancel it immediately.
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.
