Something isn't working

Margin Plus or billing

My account or data

An idea

Please don't include passwords or card numbers.

My books aren't showing on another device

Sign in with the same email on both devices. Books upload once and then open anywhere; a book added while offline uploads as soon as you're back online.

Restoring Margin Plus

Open Account in the app and tap Restore purchases, signed in to the same Apple Account you bought with.

Cancelling Margin Plus

Subscriptions are managed by Apple: open Settings, tap your name, then Subscriptions. If Plus ends, nothing is locked or deleted; every book you have stays readable.

Deleting your account

Open Account in the app and tap Delete account. Everything you've added is removed.

Privacy

What Margin keeps and why is described in the privacy policy.
