Interleaf is made by one person, Fuuqiu. Mail sent here is read by that person.

How long until you hear back

Usually within a couple of days. It is one person answering, so a weekend or a time zone can stretch that — but every message is read.

Something broke

Tell me what you were doing, what happened instead, and what you expected. These four lines turn most reports into a fix on the first reply:

The steps that led to it, in the order you did them.
Your iPad model and iPadOS version.
The Interleaf version, from the bottom of Settings.
A screenshot, if the problem is something you can see.

Something is missing

Ideas are welcome, especially the ones that make the app do less. Interleaf is meant to stay small.

About a purchase

Pro is sold through the App Store, so Apple holds the billing. To cancel a subscription, open Settings → your Apple Account → Subscriptions. Refunds are requested from Apple, not from me — I can't issue one and never see your payment details. Anything else about Pro, write to me and I'll help.

What I can't do

I can't recover anything from a lost or reset device. Nothing is stored on a server, which is what keeps your data private — and also means there is no copy to restore from unless you had turned iCloud backup on.
