Terms of Sale

What you buy, in plain words.

These terms cover the copy of Mac Deficit you buy from this site. By buying or using the app you agree to them. They are short on purpose; if anything is unclear, ask us.

Who sells it

Mac Deficit is made by RawData Studio ("we"). The direct download is sold by Polar, which acts as the seller of record: it takes the payment, charges and pays any sales tax or VAT, sends your receipt and delivers the download. Polar's terms for buyers apply to the payment. These terms cover the app itself.

A copy bought on the Mac App Store is covered by Apple's terms and Apple's standard licence for apps, not by this page.

The licences

You are buying a licence to use the app, which stays ours. There are two, and they are the same app and the same download:

• Personal: for one person, on every Mac that person uses.
• Family: for up to three people in one household, each on the Macs they use.

The app asks for no licence code and never checks. We trust you to buy the licence that fits, and to buy one for the people who use it. Please do not share, resell or publish the download or the link to it.

Updates

• Every 1.x version is included. When a new one is out, Mac Deficit › Check for Updates… says so, and you download it from your purchase, as the update page explains.
• A major new version, such as a 2.0, may be sold separately, with a lower price for people who already own the app. The version you bought keeps working; nothing in it expires.
• Prices can change. Today's prices are launch prices. A later price does not change what you paid or what you own.

Refunds

If Mac Deficit is not right for you, write to support@macdeficit.com within 14 days of buying it and we will refund you in full. Please say which email address you bought with, and tell us what did not work for you: it is how we find what to fix. Your rights under the consumer law where you live are not reduced by anything on this page.

What we promise, and what we cannot

Mac Deficit is built to be careful. It shows the size of anything before it is removed, moves things to the Trash by default so they can be put back, and never offers for removal the folders macOS and your account depend on. Even so, it is you who choose what to remove, and no software is free of mistakes.

• Keep a backup. Before you remove anything you cannot replace, make sure it is backed up, for example with Time Machine. Something deleted immediately, or removed from the Trash, cannot be brought back by the app.
• The app is provided "as is". To the fullest extent the law allows, we make no promise that it will be free of errors, or that it suits a particular purpose, beyond what these terms say.
• Our liability is limited. To the fullest extent the law allows, we are not responsible for lost data, lost files, or any indirect or consequential loss from using the app, and our total responsibility for anything to do with it is no more than what you paid for it.

Some places do not allow these limits, or allow only part of them. Where that is so, they apply only as far as the law there permits.

Other software in the app

Mac Deficit includes open-source components, each under its own licence. They are listed, with their terms, in the app under Mac Deficit › Acknowledgements.

Changes

If these terms change, this page will say so, with the date. A change does not take back anything you already bought.
