Useful details to include

A local report or practice-counter summary is optional. Nothing needs to be uploaded to ask a question. Never send your Apple Account password, verification codes or payment-card details.

• Your device model, iOS version and Tack Lab version.
• The lesson, harbor passage or replay you were using, plus the steps that led to the problem.
• The exact error message and, if useful, a screenshot with unrelated personal information removed.

Free content and Pro

The first two lessons, basic Open water sailing and the first passage in Lantern Harbor are free. Pro is a one-time, non-consumable purchase for the other four lessons, eight more harbor passages and daily practice with wind generated from the local date. It is not a subscription.

Watching an existing local replay is free. Starting or resuming Pro content, including taking the helm from its logbook replay, requires access to that content. The purchase screen shows the offer and price supplied by Apple; this website does not quote a price.

Restore a purchase or resolve a pending purchase

Restoring Pro restores an eligible purchase entitlement, not local progress or deleted replays. Apple’s official restore guidance is linked below. If Apple has charged you and access is still missing, contact us with the error and relevant purchase information, excluding payment-card details.

• Use the Apple Account that made the purchase, then open Harbor → Settings → Restore purchases. Restore is also available on the Pro screen.
• Allow an internet connection for Apple to check the purchase. If the store is unavailable or verification fails, keep the error message and try restoring later; free content remains available.
• If the app says Awaiting approval, the purchase has not yet granted access. Wait for Apple’s approval flow rather than repeatedly trying to buy the same item.

Refund requests

For purchases billed by Apple, request a refund through reportaproblem.apple.com. Apple determines eligibility under its policies and applicable consumer rights. We cannot promise approval or a refund-processing time. Use the official refund guide below for the current steps.

Progress, recovery and replays

Tack Lab keeps up to 12 recent voyages and one unfinished-voyage recovery checkpoint locally. Each replay holds up to the last 20 minutes. Older replay files may be removed as new records are saved; achievements are kept separately.

A rewind goes back up to 12 seconds within the available recording. A saved replay lets you review recorded moments; it is not a backup of every voyage you have ever sailed.

If a recording will not open or a storage error appears, send the exact message before deleting anything. Deleting all progress or reinstalling can remove local records; restoring a purchase does not bring those records back. Device backups are managed through your system settings.

Controls and lesson progress

Read the current stage goal and coaching message. A target heading alone may not complete a stage: some stages also require effective trim, enough speed, moderate helm input and a continuous hold. The first lesson manages both sails; later lessons generally leave the main to you while the virtual crew handles the jib.

Settings includes a left-handed layout and an optional physical-tiller direction. These change how controls are presented or interpreted, so check the cockpit labels. You can pause before reviewing the controls or your replay.

Virtual practice only

The fictional boat, harbors and simplified lessons are a game, not live navigation or emergency guidance. Completing them is not a sailing qualification. For real boats, use current local information and instruction from a qualified instructor.
