Purchases and subscriptions
How does the free trial work?
Eligible new subscribers can try Tone Caliper free for 7 days with a monthly or yearly subscription. Unless cancelled before the trial ends, the subscription automatically renews at the price shown when you subscribe.
How do I cancel my subscription?
Subscriptions are managed through your Apple Account. On iPad, open Settings → your name → Subscriptions → Tone Caliper to view, change, or cancel your subscription.
I already purchased Tone Caliper, but it's asking me to purchase again.
Open Tone Caliper and choose Restore Purchases from Settings. Make sure you're signed into the App Store with the same Apple Account that was used for the original purchase.
Does the Lifetime purchase expire?
No. Lifetime is a one-time, non-consumable purchase that permanently unlocks Tone Caliper for the Apple Account used to purchase it.
Can I switch between Monthly and Yearly?
Yes. Subscription changes are managed through your Apple Account subscription settings.
Does my iPad purchase unlock the Windows or macOS version?
No. Tone Caliper for iPad and Tone Caliper for desktop are currently separate products with separate licenses.
Photos and privacy
Tone Caliper uses Apple's system photo picker to import photographs. Your photographs are processed locally on your iPad and are not uploaded to Tone Caliper servers.
Tone Caliper doesn't require an account.
