Margin is a Bible reading and study app for iOS. Reading the included public-domain translations is free. The Pro study tools are a one-time purchase. Any AI features that carry an ongoing server cost are offered separately and clearly labeled.
Purchases are handled by Apple through the App Store. A one-time purchase unlocks the Pro features on your Apple ID, including Family Sharing where enabled. Refunds are handled by Apple under their standard policy.
AI answers are generated by a language model and can be wrong or incomplete. They are a study aid, not an authority. Always weigh them against Scripture itself. Do not rely on AI output for decisions of consequence.
Use Margin for personal study and devotion. Do not attempt to disrupt, abuse, or reverse-engineer the service, including the AI proxy.
Margin is provided "as is," without warranty of any kind. To the extent permitted by law, we are not liable for any damages arising from use of the app.
