Cusp is published by Norea Studio (Berke Kahraman). Downloading it from the App Store also binds you to Apple's Licensed Application End User License Agreement. Where that and this page disagree, Apple's wins.
Use Cusp on the devices tied to your App Store account, for personal or commercial work. Your threads and the files Cusp mirrors are yours.
Resell the app or circumvent the purchase mechanism. Reverse engineering is permitted only where local law requires it to be.
Cusp Plus is an auto-renewing subscription billed through your App Store account, renewing unless cancelled at least 24 hours before the period ends. Manage or cancel in Settings → your name → Subscriptions. Prices are shown in your currency by the App Store before purchase.
Apple handles refunds at reportaproblem.apple.com. I cannot issue one, but I do want to hear what went wrong.
Cusp is provided as is, maintained by one person. Its design puts your record in plain files on your own disk specifically so that a failure on my side cannot take it from you. Keep your own backup of anything you would be upset to lose.
Türkiye, without regard to conflict-of-law rules, and without limiting consumer rights you hold where you live.
