Price and licence

The website lifetime licence costs £15.99 as a one-time payment, with no monthly or annual renewal. Check the currency and final total shown in checkout before paying.

The licence lets you use Interval Pro in the website version on Macs you own or control. It cannot be resold or shared with other people. Lifetime describes this licence to use the purchased app; it does not guarantee that every future product, cloud service or version of macOS will be supported forever. Updates made available for this website app arrive through Sparkle.

Compatibility and delivery

Interval requires macOS 26 or later. After payment is confirmed, Interval emails you a download-page link and activation key. Enter the key on that page to start the DMG download, drag Interval to Applications, then enter the same key in the app to activate your Mac. An internet connection is required for purchase, activation and updates. RevenueCat verifies Pro access; Stripe processes the website payment. One lifetime license covers two active Macs. Each Mac requires the activation key and a device authorization. Verified Macs can work offline for up to 24 hours before renewing their authorization. Restarting the Mac requires online verification. The website version requires a working Secure Enclave. Removing a Mac or refunding a purchase blocks server access immediately; an offline Mac can retain access until its existing authorization expires.

Keep your activation key private. It unlocks your download and activates up to two Macs. Email verification on the download page is required only to recover a lost key or remove an old Mac. If you lose access, contact support with your purchase email and receipt. Website and App Store purchases are separate channels; install one Mac version at a time.

Refunds and your rights

You may request a refund within 14 days of your website purchase, including after download or activation. Email support with your purchase email or receipt. Approved refunds go back to the original payment method; your bank controls when they appear. Refunding a lifetime purchase removes the associated Pro access, downloads and updates when those services next check the purchase.

This refund policy does not limit your statutory rights, including rights when digital content is faulty, not as described or causes damage. Contact support if something is wrong, including after the 14-day period. App Store billing and refund requests are handled by Apple.
