Terms of Service: Quarter Inch: Quilt Calculator

These terms are the agreement between you and us for using Quarter Inch. We've kept them short and in plain language. By installing or using the app you agree to them. If you don't agree, please don't use the app.

1. Who we are

Quarter Inch is made by Async Technology, operated by Nyan Lynn Htun ("we", "us"). You can reach us at me@asynctechnology.co.nz, and we read every email.

2. Using the app

We give you a personal, non-exclusive, non-transferable licence to install and use Quarter Inch on Android devices you own or control, for your own quilting. That includes quilts you make to sell or to make for customers. You don't need an account.

You may not:

• copy, sell, rent or redistribute the app, or pass it off as your own;
• reverse-engineer or modify it, except as far as the law allows you to;
• use it to break the law or to interfere with the app, Google Play or other people's devices.

Your use of Google Play is also covered by Google's own terms.

3. Free features and Pro

Free. Every calculator is free to use, with no time limit and no ads.

Pro adds the quilt-top planner, saved quilts and the shopping-list PDF. It is a one-time purchase through Google Play. It isn't a subscription, so there's nothing to renew or cancel.

• Price. The price is shown in Google Play before you buy and may vary by country. Google processes the payment under its own terms. We never see your payment details.
• Refunds. Refunds are handled by Google Play under its refund policy: https://support.google.com/googleplay/answer/2479637. If something isn't working, email us. We'll try to fix it, and this doesn't affect your rights under section 9.
• Restore. Pro is linked to the Google account you bought it with. On a new or reset device, sign in to Google Play with the same account and tap Restore purchase (in Settings or on the Pro screen). Buying and restoring need an internet connection. The calculators don't.

4. Your data

The Privacy Policy explains what the app stores on your device and what it sends (usage statistics and crash reports, which you can turn off in Settings): https://asynctechnology.co.nz/quarter-inch/privacy/

5. About the numbers: please check before you cut

Quarter Inch is a planning aid. Its results are estimates worked out from the numbers and settings you enter, such as sizes, fabric width, seam allowance, extra % and rounding. Real fabric doesn't always match: usable width varies between bolts, fabric shrinks, and cuts can drift. We test the maths carefully and show the working with every answer (see also Settings → How we calculate), so you can check it.

So please:

• check the result before you buy or cut fabric, especially expensive or hard-to-replace fabric;
• make sure the numbers you entered and your settings are what you meant;
• if you like a margin, allow some extra fabric (the "Extra fabric" setting can add it for you).

If a number looks wrong, tap Report a number that looks wrong under the answer. It opens your own email app with the details filled in, and you decide whether to send it. Fixing the maths always comes first for us.

To the extent the law allows, we aren't responsible for the cost of fabric or materials you buy or cut based on the app's results, because the decision to buy and cut is yours to check. This doesn't limit your rights under section 9.

6. Ownership

The app, its design, text, graphics and calculation methods belong to us or our licensors. These terms don't transfer any of that to you. Your quilts, plans and anything you make with the app's help are yours.

7. Changes to the app

We may update the app to fix problems, change features or add new ones. We won't remove the main Pro features you paid for in an update, unless we have to for legal, security or technical reasons beyond our control (for example, a change by Google or Android). We don't run servers that the calculators depend on, but we can't promise the app will keep working on every future device or Android version.

8. Changes to these terms

If we change these terms, we'll post the new version at https://asynctechnology.co.nz/quarter-inch/terms/ and update the effective date. If a change is significant, we'll also mention it in the app's release notes. Changes apply from the new effective date. If you don't agree with them, you can stop using the app (section 10).

9. Warranties, liability and your consumer rights

Your consumer rights come first. Nothing in these terms takes away or limits any right you have that can't legally be excluded. This includes your rights under the New Zealand Consumer Guarantees Act 1993 if you are a consumer in New Zealand, and your rights under EU or UK consumer law if you are a consumer there. If anything in these terms conflicts with those rights, those rights win.

Within those limits:

• The app is provided "as is" and "as available". We don't promise it will be free of errors or always available, or that it suits every quilting method.
• We aren't liable for indirect or consequential loss, such as lost profit, lost time or wasted materials beyond what section 5 describes.
• Our total liability to you for anything connected with the app is limited to the amount you paid for Pro, if any.
• We don't exclude liability for death or personal injury caused by our negligence, for fraud, or for anything else the law doesn't allow us to exclude.

10. Ending use

You can stop using Quarter Inch at any time by uninstalling it. Uninstalling removes the app's data from your device. Copies in your Android backup follow your Google account's backup settings (see the Privacy Policy). Pro stays linked to your Google account if you reinstall later.

If you seriously break these terms, we may end your licence to use the app, as far as the law allows. Sections 5, 6, 9 and 11 keep applying after your use ends.

11. Governing law

These terms are governed by the laws of New Zealand, and the New Zealand courts can hear disputes about them. If you are a consumer living in another country, you keep the protection of the mandatory consumer laws of your country, and you may also be able to bring a claim in your local courts. If any part of these terms can't be enforced, the rest still applies.
