Common questions

How do I cancel my subscription?

On your iPhone: Settings → tap your name → Subscriptions → Curve Pro → Cancel Subscription. The cancellation takes effect at the end of your current billing period, and you keep Pro access until then.

I bought Lifetime — do I need to renew?

No. Lifetime is a one-time payment. It includes Family Sharing, so anyone in your Apple Family can also use Curve Pro on their devices at no extra cost.

I lost my Pro access after reinstalling or on a new phone

Open Curve → Settings → Upgrade to Pro → tap Restore in the top right. This re-checks your Apple ID for prior purchases. If that doesn't work, email us with the Apple ID (just the name, not the password) and we'll help.

Where is my data stored?

On your device, using Apple's SwiftData. If you enable iCloud sync it syncs through your private iCloud — we never see it. See Privacy for details.

How do I export my data?

The Share tab generates a vet-ready PDF of any date range. A full CSV export is on the roadmap — email us if you need it sooner and we'll do it manually.

Curve crashed or lost data

Please email us with a description and, if possible, the steps that led to it. Curve uses SwiftData with a fall-back-to-in-memory recovery path on corruption, but we want to fix any case where data is lost.

Refunds

Refunds are handled by Apple directly: reportaproblem.apple.com. We don't process them because Apple holds the transaction. Email us first if Apple denies the refund and you feel strongly — we'll try to help.

I have a feature request

Email us. Curve is built from real feedback from the diabetic-cat community, and we read every message.

Is there a hypoglycemia alarm?

No — this is intentional. Curve is a record-keeping tool, not a medical device. If you suspect your cat is hypoglycemic, contact your veterinarian or emergency animal hospital immediately. See our Terms for the full medical disclaimer.
