Terms of Use

What Ballista Does

Ballista helps users record tee-hitting sessions with an iPhone and keep a swing history. It uses video analysis to estimate metrics such as exit velocity, launch angle, and projected distance.

Estimated Metrics

Ballista metrics are estimates produced from iPhone video analysis. They are not official or certified radar measurements, and they are not scouting, recruiting, medical, or professional evaluation results. Recording conditions, camera position, calibration, lighting, visibility, and other factors can affect whether a metric is available and how accurate it is.

Use Ballista as a player-development and practice-tracking tool. Do not rely on its estimates as the sole basis for training, health, safety, recruiting, or professional decisions.

Safe Training and Equipment

You are responsible for setting up and conducting baseball training safely. Keep the iPhone, tripod, other devices, and people a safe distance from the hitter, bat, and ball. Follow the safety instructions for your training space and equipment.

You accept responsibility for injury risk and for loss of or damage to an iPhone, tripod, or other equipment used with Ballista.

Accounts and Deletion

You are responsible for your account credentials and for activity through your account. Account deletion is available in the app through Profile → Account Settings → Delete Account. Completed deletion removes the cloud account and associated profile, player, and hit data. The app separately lets you choose whether to delete that account’s local hit data from the iPhone. See our Privacy Policy for data handling, deletion limitations, and provider retention.

Deleting your Ballista account or the app does not cancel an App Store subscription. Apple billing can continue until you cancel through Apple’s subscription settings. Account deletion is available without cancelling first. Before deleting an account with an active subscription, read the restoration limitation below.

Ballista Free and Pro

Ballista Free includes hit capture and analysis, immediate metrics, current-session results, cloud synchronization, and basic replay for accessible hits when local replay media is available. Historical access is limited to the latest 25 hits, with current-session results and hits needing analysis recovery also accessible. This access limit does not automatically delete older records.

Ballista Pro unlocks unlimited access to available hit history, simulated 3D Flight, the development dashboard, training calendar, and session comparisons. Feature availability depends on the required hit data and media. Pro does not provide a cloud backup or recovery of full replay videos or original replay frames. Cloud history can restore synchronized results and metadata, without the original replay media.

Coach or Team descriptions and features marked “Coming soon” are not included in these consumer Pro subscriptions. Future feature descriptions or pricing do not promise a launch date or a particular form.

Subscriptions, Billing, and Renewal

Ballista Pro is offered through Apple’s in-app purchase system as monthly and annual auto-renewable subscriptions. Sign in to your Ballista account before purchasing. The paywall and Apple’s purchase confirmation show the available plan, localized price, billing period, and renewal information before you confirm. Apple processes payment through your Apple Account and manages billing and renewals. Subscriptions renew automatically for the selected period unless you cancel through Apple.

A free trial applies only if Apple reports an eligible offer and it is shown in the purchase flow. The trial duration and price payable afterward are shown before confirmation. Unless cancelled under Apple’s offer terms, the trial converts to the paid auto-renewing subscription. No trial or fixed price is promised to every user.

Pro activates after Apple confirms a verified, eligible purchase linked to the signed-in Ballista account. A pending or unverified purchase does not activate Pro.

Cancellation, Expiry, and Refunds

Use Manage Subscription in the app’s Account Settings, or open Apple’s subscription settings, to manage or cancel renewal. You can also use iPhone Settings → your name → Subscriptions. Apple’s cancellation instructions explain the process, including trial cancellation timing.

Cancelling renewal does not by itself immediately remove Pro: access continues for the original Ballista account while Apple reports a valid entitlement, normally through the paid period’s expiry. Trial access follows Apple’s offer terms. Pro ends when the entitlement expires or Apple revokes it, including following a refund. A valid Apple-reported billing grace period can retain access; billing retry without a valid grace period does not. Ballista Free remains available when Pro ends, and expiry alone does not delete older hit records, although Free history limits apply.

Request refunds for Apple-billed purchases through Apple’s refund process. Eligibility and approval are determined by Apple’s applicable terms and consumer law; Ballista does not guarantee a refund. Nothing in these terms limits rights you have under applicable consumer law.

Restore Purchases and Account Ownership

Restore Purchases is available on the Pro paywall and in Account Settings. Use the Apple Account that made the purchase and sign in to the original Ballista account used for it. Restoration checks the subscription with Apple and requires a verified active entitlement linked to that Ballista account; it does not transfer ownership between Ballista accounts or restore deleted account data.

If you delete your original Ballista account and create a new one, Restore Purchases cannot currently recover that subscription’s Pro access on the new account. Purchases with a missing account link also require ownership review. Automatic account-recreation recovery is not available. Contact Ballista Support for review; recovery or transfer is not guaranteed. Do not buy another subscription to recover access. Apple billing may continue while ownership is unresolved; use Apple’s subscription settings to manage it, or Apple’s refund process to request a refund.

Availability and Changes

Ballista may change as it is tested and improved. Features may be updated, limited, or unavailable, and we do not promise uninterrupted or error-free operation. We may update these terms as Ballista evolves by posting the revised version on this page.
