Please read these Terms of Service ("Terms") carefully before using the FoldFX Android application (the "App") or this website (the "Site"). These Terms are an agreement between you and the FoldFX team ("the Developer", "we", "us") governing your access to and use of the App and the Site. By downloading, installing or using the App, or by browsing the Site, you agree to be bound by these Terms.
1. Agreement and eligibility
By using the App you confirm that you are at least 13 years old (or the minimum digital-consent age in your country) and that you have the legal capacity to enter into these Terms. If you are using the App on behalf of an organization, you represent that you have authority to bind that organization to these Terms. If you do not agree with any part of these Terms, do not install or use the App.
2. License grant
Subject to your compliance with these Terms, the Developer grants you a limited, non-exclusive, non-transferable, revocable license to download, install and use the App on devices you own or control, for your personal, non-commercial purposes. This license covers the App as distributed by the Developer directly through the official FoldFX website.
Payments and license keys. FoldFX is sold as a one-time purchase of €4.99 through Polar.sh, the Developer's payment processor and merchant of record. A purchase delivers a license key by email; each key can be activated on exactly one device at a time, and it can be deactivated in-app at any time to move it to another device. The App is offered without a free trial period — the on-site live demo shows the product before purchase. Refunds are processed through Polar; if a payment is refunded, the associated license key is revoked and the App locks. Where applicable, taxes are calculated and remitted by Polar.
3. Acceptable use
You agree that you will use the App only as intended and in accordance with all applicable laws. When using the App you agree not to:
- Use the App in any way that could damage, disable, overburden or impair any device or interfere with any other user's enjoyment of the App;
- Reverse engineer, decompile or disassemble the App except to the extent expressly permitted by applicable law notwithstanding this limitation;
- Redistribute, sublicense, rent, lease or sell the App, or remove any proprietary notices from it;
- Present the App or its effects as your own product, or misrepresent any affiliation between the App and any third party, platform vendor or device manufacturer;
- Use the App to violate any applicable law, regulation or third-party right.
4. Intellectual property
The App, the Site and their entire contents — including the FoldFX name, logo, design, source code, animations and all related assets — are owned by the Developer and are protected by copyright and other intellectual-property laws. All rights not expressly granted to you in these Terms are reserved.
5. Third-party trademarks and services
FoldFX is an independent project. It is not affiliated with, endorsed by, sponsored by or derived from any platform vendor or device manufacturer. The effect implemented by the App is an original implementation of a generic UI technique (blending two layouts using a live angle value), built from scratch with original code, names and assets. The App also depends on operating-system services and sensor hardware provided by your device manufacturer; those are governed by their own terms, and the Developer is not responsible for their availability or behavior.
6. Functionality and device requirements
The App requires a device running Android 8.0 (API 26) or later; a foldable device is required for the sensor-driven experience, and on devices without a hinge-angle sensor the App approximates the effect from fold-state information. The App's effect applies within the App's own interface and to its live wallpaper; it cannot and does not modify system-wide or third-party application transitions, which are controlled by the operating system and device manufacturer. The experimental overlay mode renders an effect over other apps' screens only with your explicit permission, through Android's accessibility and screen-capture APIs. Features may evolve as the App is developed, and we may add, change or remove functionality at any time.
7. Disclaimer of warranties
The App and the Site are provided "as is" and "as available", without warranties of any kind, whether express, implied or statutory, including but not limited to warranties of merchantability, fitness for a particular purpose, accuracy, non-infringement and uninterrupted operation. We do not warrant that the App will function identically on every device, that sensor data will be available or accurate on your particular hardware, or that the App will be free of bugs or errors. You use the App at your own risk.
8. Limitation of liability
To the maximum extent permitted by applicable law, in no event will the Developer be liable for any indirect, incidental, special, consequential or punitive damages, or any loss of profits, data, goodwill or other intangible losses, arising out of or relating to your use of (or inability to use) the App or the Site. In no event will the Developer's total aggregate liability for all claims exceed the amount you paid for the App (which, for the free release, means zero) or, if applicable law requires a monetary cap, the minimum amount permitted by that law. Some jurisdictions do not allow certain exclusions or limitations, so parts of this section may not apply to you, in which case the limitations apply to the greatest extent legally permitted.
9. Termination
You may stop using the App and delete it at any time. The Developer reserves the right to suspend or terminate your access to the App, with or without notice, if you materially breach these Terms or if required by law. Upon termination, the license granted in section 2 ends immediately, and sections 4, 5, 7, 8 and 10 survive termination.
10. Governing law and disputes
These Terms are governed by the laws of the country in which the Developer resides, without regard to conflict-of-law rules. You and the Developer agree to attempt in good faith to resolve any dispute informally before pursuing formal action, and you agree to bring claims only in your individual capacity, not as a plaintiff or class member in any class or representative proceeding. Mandatory consumer-protection rights in your country of residence are not affected by these Terms.
11. Changes to the App or these Terms
We may update the App and these Terms from time to time. When these Terms change, the "effective date" at the top of this page will be revised, and continued use of the App after the new effective date constitutes acceptance of the updated Terms. If a change is material, we will also note it in the App's release notes. If you do not agree to updated Terms, you should stop using the App and uninstall it.
