Terms of Use

Effective September 26, 2026.

These terms are between you and XZ Industries LLC ("XZ Industries", "we") for the StoneLab app. By downloading or using StoneLab, you agree to them. They apply together with Apple's standard Licensed Application End User License Agreement. Where Apple's standard terms must control, they control.

1. License

We give you a personal, non-exclusive, non-transferable license to use StoneLab on Apple devices you own or control, as permitted by the App Store terms. You may use StoneLab for personal and commercial work.

2. Your content

You retain your rights in the designs, artwork, photos and files you bring into StoneLab and the files you export. XZ Industries claims no ownership of that content and does not receive your project files through the app. You are responsible for having the rights needed to use anything you import, including artwork, photos, logos, trademarks and fonts.

3. Fonts

StoneLab can use fonts available on your device and fonts you import. StoneLab does not grant you a license to any third-party font. If you import a font, you are responsible for having a license that covers your intended use, including creating stone patterns and storing the font in a portable project file when applicable.

4. Check your work before production

StoneLab computes stone layouts, counts, dimensions, spacing and export files. Results can also depend on your input, printer, cutting machine, material and third-party software. Always make a test print or test cut and verify physical measurements before producing a finished item or purchasing material in quantity. Supply lists and quotes are estimates based on the values you enter.

5. Your projects on your device

StoneLab stores project data locally unless a feature you explicitly use stores or shares a copy elsewhere through Apple or another service you choose. Keep exported project copies or device backups for work you cannot afford to lose.

6. Acceptable use

Do not use StoneLab to break the law or infringe another person's rights. Do not reverse engineer StoneLab except to the extent the law expressly permits, and do not misrepresent StoneLab or XZ Industries.

7. No warranty

To the fullest extent allowed by law, StoneLab is provided "as is" and "as available" without warranties of any kind. We do not promise that StoneLab will be error-free, uninterrupted, suitable for every purpose, or compatible with every third-party program, cutter, printer or machine.

8. Limit of liability

To the fullest extent allowed by law, XZ Industries is not liable for indirect, incidental, special or consequential damages, lost profits, lost data, or the cost of wasted material or time arising from your use of StoneLab. To the extent a limitation is permitted, our total liability for a claim relating to StoneLab will not exceed the amount you paid for StoneLab in the twelve months before the claim, or fifty US dollars if you paid nothing. Some jurisdictions do not allow certain limitations, so some of these terms may not apply to you.

9. Apple

These terms are between you and XZ Industries, not Apple. Apple has no obligation to provide maintenance or support for StoneLab. Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them against you as permitted by the App Store terms.

10. Changes and ending use

We may update these terms and will post the updated version here with a new effective date. You can stop using StoneLab at any time by deleting the app.

11. Governing law

These terms are governed by the laws of the State of Arizona, United States, without regard to conflict-of-law rules, except where applicable local law requires otherwise.
