Common questions
Where is my data stored?
On your iPhone, with optional sync to your private iCloud account. Some features send specific data off the phone to do their job, such as the AI features, local fuel prices and the trip on your Lock Screen, and the developer's servers keep none of it. Feedback and diagnostics reach the developer only when you choose to send them. The privacy policy lists every one and exactly what it sends.
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 Account. Data restores automatically once iCloud finishes syncing.
