Terms of Sale and Licence

Who you are dealing with

Tunestack is made by Suraj Kumar and sold only through the Mac App Store. Apple is the seller: it takes the payment, issues the receipt, and handles refunds. Your licence to use the app is Apple's Licensed Application End User License Agreement, and these terms sit alongside it without overriding it.

What you are buying

You are buying a licence to use Tunestack, not the software itself. The licence is personal to you, non-exclusive and non-transferable.

You may install and use it on any Mac signed in to the Apple Account you bought it with, for personal or business work, as the App Store allows. There is no licence key, no activation and no device quota of our own.

The price is $8.99, paid once. It is not a subscription and it does not renew. Apple sets the price shown in your country's currency, and it includes any tax.

Updates

Your licence covers version 1.0 and every later update we release under that version line, at no extra cost. If a future release is ever a separate paid product, it will be sold as one and your existing licence will keep working.

We are not obliged to release updates on any schedule, or to keep supporting versions of macOS that Apple no longer supports.

What you may not do

Please do not resell, rent, sublicense or redistribute the app, or remove copyright and identification notices from it.

You may not reverse engineer, decompile or disassemble the app, except to the extent that law expressly permits despite this restriction — for example for interoperability under applicable EU or UK law.

Refunds, and your right to change your mind

Refunds come from Apple, not from us. Because Apple is the seller, we cannot see your payment and have no way to issue a refund ourselves. Request one at reportaproblem.apple.com: sign in, choose Tunestack, and pick "Request a refund".

If you are a consumer in the UK or EU, your statutory right to withdraw from a purchase of digital content is handled by Apple under its own terms.

If Tunestack does not do what this website says it does, tell Apple that when you ask for the refund — and please tell us too, at support@tunestack.in, because it means either the app or this site is wrong and one of them needs fixing. The limitations the home page lists are there so that nobody buys on a false impression.

What you need to run it

macOS 14.4 or later · Intel or Apple silicon. If your Mac does not meet that, the app will not run, and that is a refund case — please check before buying.

What Tunestack does not promise

It cannot stop another app taking a device. An application that opens its own audio session and demands a specific device will get it. Tunestack sits above that layer: it can notice and switch back, but it cannot prevent the change.

Switching is fast, not instant. There is a deliberate short delay before it acts, because real hardware reports a single physical plug several times.

AirPlay is not claimed. Whether AirPlay devices behave like wired and Bluetooth ones has not been verified, so we do not claim it works with them.

Warranty and liability

The software is provided as it is. Beyond what these terms say, and beyond what the law requires of us, we make no other warranties — including that it will be uninterrupted or error-free.

This does not affect your statutory rights. If you are a consumer, the law of your country gives you rights about goods and digital content being as described and of satisfactory quality, and nothing here removes or limits those.

To the extent the law allows, our total liability to you for any claim connected with Tunestack is limited to the amount you paid for your licence. We do not exclude liability for death or personal injury caused by our negligence, for fraud, or for anything else that cannot lawfully be excluded.

Third-party software

Tunestack is written in Swift and uses Apple's own frameworks. This website uses Lenis and Sortable.js, both under the MIT licence, and the Geist and Geist Mono typefaces under the SIL Open Font Licence 1.1. Their licences are respected and their authors keep their copyright.

Changes to these terms

We may update these terms for future purchases. The version that applies to you is the one published on the day you bought your licence, and the date at the top of this page tells you when it last changed.

Governing law

These terms are governed by the law of India, and its courts have jurisdiction. If you are a consumer, this does not deprive you of the protection of the mandatory law of the country where you live, nor of the right to bring a claim there.
