Common questions
Where is my data stored?
On your iPhone, with optional sync to your private iCloud account. The only things that ever leave the phone are the documents and figures you send through the Pro AI features, and those are not stored anywhere. See the privacy policy for exactly what is sent.
How do I cancel a subscription?
On your iPhone: Settings → your name at the top → Subscriptions → Caliper.
How do I request a refund?
Refunds are handled by Apple. Visit reportaproblem.apple.com and find the Caliper purchase.
My data isn't there after reinstalling the app
Make sure iCloud is enabled and you're signed in to the same Apple ID. Data restores automatically once iCloud finishes syncing.
