The rules, plainly stated.

01 Acceptance of Terms

By downloading, installing, or using Extrudix ("the App"), you agree to be bound by these Terms of Use. If you do not agree, do not use the App. These terms apply to all users of the App, whether for personal or commercial purposes.

Extrudix is published by Ronet Software LLC, a Wisconsin limited liability company ("Ronet Software," "the developer," "we," "us," or "our"). Wherever these terms refer to "the developer," that means Ronet Software LLC.

02 No Affiliation with Third Parties

Extrudix is an independent application published by Ronet Software LLC. It is not affiliated with, endorsed by, sponsored by, or in any way officially connected to Bambu Lab, Prusa Research, Creality, Ultimaker, or any other 3D printer manufacturer, slicer developer, or company in the 3D printing industry.

All brand names, product names, model names, and trademarks referenced in the App, including but not limited to Bambu Lab, Bambu Studio, PrusaSlicer, Orca Slicer, and others, are the property of their respective owners and are referenced solely for identification and compatibility purposes under nominative fair use.

03 License Grant

Subject to your acceptance of these terms, the developer grants you a limited, personal, non-exclusive, non-transferable, revocable license to install and use Extrudix on devices you own or control, solely for your personal or internal business purposes.

The App is licensed to you, not sold. This license does not include the right to sublicense, resell, distribute, or otherwise transfer the App or any rights in it to any third party.

04 In-App Purchases and Tiers

Extrudix offers optional in-app purchases ("IAP") that unlock additional features and higher usage limits. Purchases are processed exclusively through Apple's App Store using Apple's In-App Purchase system. The developer does not directly handle payment information.

Plus is a non-consumable one-time purchase. Once purchased, the Plus tier is permanently associated with your Apple ID. You will not be charged again for Plus on any device signed in to the same Apple ID.

Pro is an auto-renewable monthly subscription at $4.99/month. Payment is charged to your Apple ID at confirmation of purchase. The subscription automatically renews for the same price and duration unless you turn off auto-renewal at least 24 hours before the end of the current period, and your account will be charged for renewal within 24 hours before that period ends. You can manage or cancel your subscription at any time in your Apple ID subscription settings, and any unused portion of a free trial, if offered, is forfeited when you purchase a subscription. Access to Pro continues until the end of the current billing period after cancellation.

If you lose access to a purchased Plus tier (for example, after reinstalling the App or signing in on a new device), you can restore your purchase at no charge using the Restore Purchases option in the App's settings. Apple's policies govern all purchase restorations.

Refund requests must be submitted directly to Apple through Apple's standard refund process, and the developer has no authority to issue refunds directly. This does not affect any statutory right to a refund or withdrawal you may have under the law of your country, such as the European Union's 14-day withdrawal right for online purchases, which is unaffected by anything in these terms.

05 Tier Access and Grandfathering

Plus is a permanent tier. Once purchased, Plus is associated with your Apple ID indefinitely. Future price increases do not affect Plus purchasers, since you pay the price in effect at the time of your purchase and retain Plus for the lifetime of the App.

Pro access is contingent on an active monthly subscription. If your subscription lapses or is cancelled, Pro features become unavailable and your account returns to your base tier (Maker, or Plus if purchased). The developer commits not to remove features from the Pro tier without notice.

Promotional access granted through a time-limited invite key is separate from a purchased tier. Promotional access expires on the date stated in the key and does not constitute a permanent purchase. Promotional keys are non-transferable and are issued solely for personal use by the named recipient.

06 Your Data

All data you enter into the App is stored locally on your device or in a cloud storage folder of your choosing (such as iCloud Drive or Google Drive). The App itself does not collect, transmit, store, or have access to any of the printing, project, or business data you enter.

You are solely responsible for the backup, security, and management of your data.

07 Privacy

The App itself does not collect any personal information, usage data, analytics, or crash reports, and no account is required to use it. The App does make a small number of standard network requests, such as downloading the built-in catalogs and demo dataset from GitHub, which exposes ordinary connection details like your IP address to GitHub the same way any web request would. The developer's website also uses analytics. None of this is collected by the developer from within the App itself. See the Privacy Policy for the full, accurate breakdown of every category of data involved, including the website and these network requests.

08 No Warranty

The App is provided "as is" and "as available," without warranty of any kind, express or implied. The developer makes no representations or warranties regarding:

• The accuracy, completeness, or reliability of any cost estimates, calculations, or data generated by the App
• The fitness of the App for any particular purpose, including commercial or business use
• Uninterrupted or error-free operation of the App
• Compatibility with any specific slicer software, 3D printer, or file format

You use the App entirely at your own risk. Nothing in this section excludes or limits any warranty that cannot lawfully be excluded under the law that applies to you, including statutory consumer warranties in the European Union, the United Kingdom, and certain US states; where such a warranty applies, it is limited to the shortest period and narrowest scope the law allows.

09 Limitation of Liability

To the fullest extent permitted by applicable law, the developer shall not be liable for any direct, indirect, incidental, special, consequential, or punitive damages arising from your use of, or inability to use, the App, including but not limited to:

• Loss of data or files stored using the App
• Errors or inaccuracies in cost estimates used for billing, invoicing, or financial decisions
• Damage to hardware or materials arising from information provided by the App
• Loss of business, revenue, or profits

This limitation applies regardless of whether the developer has been advised of the possibility of such damages. Nothing in these terms limits or excludes liability that cannot be limited or excluded under applicable law, including liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for any other liability that the law of your jurisdiction does not permit to be excluded.

10 Cost Estimates and Financial Data

Any cost estimates, calculations, breakdowns, or financial figures generated by the App are approximations only. They are based on the settings and data you provide and are intended as a convenience tool, not as a substitute for professional accounting, financial advice, or formal invoicing.

You are solely responsible for verifying the accuracy of any figures before using them for billing, quoting, invoicing, tax reporting, or any other financial or legal purpose.

11 File Format Compatibility

The App includes features that read and parse slicer project files (such as .3mf files). These features rely on file format conventions that may change without notice by the respective slicer software developers. The developer makes no guarantee that import features will remain functional following updates to third-party slicer applications.

12 Intellectual Property

Extrudix and all of its contents, including the source code, compiled binary, user interface design, layout, visual appearance, icons, graphics, text, data schemas, and organizational structure, are the exclusive intellectual property of the developer and are protected by United States and international copyright, trademark, trade dress, and other applicable laws.

The name "Extrudix" and any associated logos or marks are trademarks of the developer. Nothing in these terms grants you any right to use the developer's trademarks, trade names, or branding without prior written permission.

All rights not expressly granted in these terms are reserved by the developer.

13 Prohibited Uses

You may not, directly or indirectly:

• Copy, reproduce, modify, adapt, translate, or create derivative works based on the App or any part of it, except to the extent this restriction is prohibited by applicable law
• Reverse-engineer, decompile, disassemble, or otherwise attempt to derive the source code, UI structure, or logic of the App, except to the extent this restriction is prohibited by applicable law, such as a non-waivable right to do so for interoperability purposes
• Use the App's design, layout, workflows, or functionality as a basis for developing a competing or substantially similar application
• Redistribute, sublicense, sell, rent, lease, or otherwise transfer the App or any rights in it
• Remove, obscure, or alter any copyright, trademark, or other proprietary notices within the App
• Share, distribute, or transfer a promotional invite key to any person other than the intended recipient

Violation of these prohibitions may constitute copyright infringement, trade dress infringement, or other actionable conduct under applicable law.

14 Changes to the App

The developer reserves the right to modify, add, or remove features of the App at any time. Where possible, advance notice will be provided through App Store release notes or within the App itself.

The developer will not move a feature that is currently available in a purchased tier to a higher tier without advance notice and without honoring existing purchasers' access. Free-tier features may be adjusted over time, but paid-tier purchasers will not lose features they paid for.

Continued use of the App following any changes constitutes your acceptance of the updated offering.

15 Changes to These Terms

The developer reserves the right to update these terms at any time. When the terms are updated in a material way, you will be asked to review and accept the updated version before continuing to use the App. Continued use of the App after acceptance constitutes agreement to the revised terms.

16 Feedback

If you submit feedback, feature requests, bug reports, or suggestions to the developer, through any channel including the in-app feedback form, App Store reviews, or direct contact, you grant the developer a perpetual, irrevocable, royalty-free, worldwide license to use, incorporate, and act on that feedback for any purpose, without compensation or attribution to you.

You represent that any feedback you submit does not contain confidential or proprietary information belonging to a third party.

17 Apple App Store Terms

This section applies if you downloaded the App from the Apple App Store, and supplements the rest of these terms. In the event of a conflict between this section and any other part of these terms regarding your relationship with Apple, this section governs.

This agreement is between you and the developer only, not Apple, and Apple is not responsible for the App or its content. To the extent there is any conflict between these terms and the Apple Media Services Terms and Conditions, the more restrictive term applies.

The license granted to you in these terms is limited to a non-transferable license to use the App on any Apple-branded products that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions.

Apple has no obligation to furnish any maintenance or support services for the App. To the extent any such obligation exists under applicable law, it is the developer's, not Apple's.

Apple is not responsible for any product warranties, whether express or implied by law. If the App fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price for the App to you, if any; to the maximum extent permitted by applicable law, Apple has no other warranty obligation with respect to the App, and any other claims, losses, liabilities, damages, costs, or expenses attributable to a failure to conform to a warranty are the developer's responsibility.

The developer, not Apple, is responsible for addressing any claims by you or any third party relating to the App or your possession or use of it, including product liability claims, any claim that the App fails to conform to a legal or regulatory requirement, and claims arising under consumer protection, privacy, or similar legislation.

If a third party claims the App infringes that party's intellectual property rights, the developer, not Apple, is solely responsible for the investigation, defense, settlement, and discharge of any such claim.

You represent that you are not located in a country subject to a US government embargo or designated as a "terrorist supporting" country, and that you are not listed on any US government list of prohibited or restricted parties.

If you have any questions, complaints, or claims regarding the App, they should be directed to the developer at the contact details in Section 19, not to Apple.

You and the developer acknowledge that Apple and Apple's subsidiaries are third-party beneficiaries of these terms, and that upon your acceptance of these terms, Apple will have the right, and will be deemed to have accepted the right, to enforce these terms against you as a third-party beneficiary.

18 Governing Law

These terms shall be governed by and construed in accordance with the laws of the State of Wisconsin, United States of America, without regard to conflict of law provisions. Any disputes arising from these terms or your use of the App shall be resolved in the courts of Racine County, Wisconsin. If you are a consumer in the European Union or United Kingdom, this choice of law does not deprive you of the protection of any mandatory consumer protection provisions of the country in which you reside.
