Terms of Service

1. About Tayu

Tayu is a desktop wallpaper application for macOS and Windows. It plays user-selected video, image, and YouTube backgrounds as a live wallpaper, with optional ambient sound and schedules. Tayu is offered as a free tier with optional paid plans that unlock additional features.

2. License to use Tayu

Subject to your compliance with these Terms, we grant you a personal, non-exclusive, non-transferable, revocable licence to install and use Tayu on devices you own or control, for your personal or internal business use. You may not:

• Copy, modify, reverse engineer, decompile, or attempt to derive the source code of Tayu, except as expressly permitted by applicable law.
• Sell, sublicense, rent, lease, or otherwise distribute Tayu or your access code.
• Circumvent or interfere with the licensing, entitlement, or technical protection mechanisms of Tayu.
• Use Tayu to infringe the intellectual property, privacy, or other rights of any third party.

We may update, change, or discontinue features of Tayu over time. We will give reasonable notice before removing a paid feature that you currently rely on.

3. No account required

Tayu does not require you to create a user account. The app uses an anonymous per-install identifier to link your installation with any paid plan you purchase. You are responsible for keeping any access code we issue to you safe.

4. Free and paid plans

Tayu offers a free tier that does not require payment. Paid plans (monthly, yearly, or lifetime) unlock additional features described on the pricing page. The current price, billing frequency, currency, and any trial terms are shown to you at checkout and form part of these Terms once you complete payment.

5. Payments and Merchant of Record

Our order process is conducted by our online reseller Paddle.com. Paddle.com is the Merchant of Record for all our orders. Paddle provides all customer service inquiries and handles returns.

Paddle.com Market Limited (“Paddle”) is responsible for billing, applicable taxes (including VAT, GST, sales tax), invoicing, payment-method support, and chargeback handling. Your purchase is also governed by the Paddle Buyer Terms and the Paddle Privacy Policy, in addition to these Terms.

Subscriptions automatically renew at the end of each billing period at the then-current price unless you cancel before renewal. You can cancel at any time from Settings → Manage subscription in the Tayu app, which opens the Paddle customer portal.

6. Refunds

We offer a 14-day money-back guarantee on first-time purchases of paid plans. Full details are in our Refund Policy, which is incorporated into these Terms by reference.

7. Your content and responsibility

Tayu lets you import or reference media (images, videos, audio, YouTube URLs) to use as wallpapers and ambient backgrounds. You are responsible for ensuring you have the necessary rights to use that media on your device and in compliance with the terms of any third-party platform from which it originates (for example, YouTube’s Terms of Service for YouTube content). We do not host, distribute, or claim any ownership of your content.

8. Acceptable use

You agree not to use Tayu to:

• Violate any applicable law or regulation.
• Display content that is illegal, defamatory, sexually explicit involving minors, or that incites violence.
• Attempt to gain unauthorised access to our systems or other users’ entitlements.
• Interfere with or disrupt the integrity or performance of Tayu or our backend services.

We may suspend or terminate your access to paid features if we reasonably believe you have materially breached these Terms.

9. Intellectual property

Tayu, including its software, logos, website, and documentation, is owned by Nono (Makoto Nonoyama) and protected by copyright and other intellectual property laws. Nothing in these Terms transfers ownership of Tayu to you. All rights not expressly granted are reserved.

10. Third-party services

Tayu may interact with third-party services, including YouTube (for playable URL backgrounds), Paddle (for payments), and Cloudflare (for hosting). Your use of those services is governed by their own terms and privacy policies. We are not responsible for the availability, accuracy, or content of third-party services.

11. Export controls and international use

Tayu is provided from Japan and may be subject to export-control and sanctions laws of Japan, the United States, the European Union, the United Kingdom, and other jurisdictions. You represent and warrant that you (a) are not located in, and are not a national or resident of, any country subject to a comprehensive embargo by Japan, the United States, the European Union, or the United Kingdom (currently including but not limited to Cuba, Iran, North Korea, Syria, and the Crimea, Donetsk, and Luhansk regions of Ukraine), (b) are not on any restricted-party, denied-persons, or sanctioned-individuals list maintained by those governments (including the U.S. OFAC Specially Designated Nationals list and the U.S. Department of Commerce Entity List), and (c) will not use Tayu to develop, design, manufacture, or produce nuclear, missile, chemical, or biological weapons, or for any other use prohibited by applicable export-control laws.

You are responsible for complying with all applicable export-control and sanctions laws in your jurisdiction. We may suspend or terminate your access if we reasonably believe your use of Tayu would violate these laws.

12. Disclaimers

Tayu is provided on an “as is” and “as available” basis. To the maximum extent permitted by applicable law, we disclaim all warranties, whether express, implied, statutory, or otherwise, including warranties of merchantability, fitness for a particular purpose, non-infringement, and quiet enjoyment. We do not warrant that Tayu will be uninterrupted, error-free, or that defects will be corrected, or that the service will be free of viruses or other harmful components.

Some jurisdictions do not allow the exclusion of certain warranties, so the above exclusions may not apply to you.

13. Limitation of liability

To the maximum extent permitted by applicable law, our aggregate liability to you for any claim arising out of or relating to Tayu or these Terms will not exceed the greater of (a) the amount you paid us for the Tayu paid plan in the twelve (12) months immediately preceding the event giving rise to the claim, or (b) USD 50.

In no event will we be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, including loss of profits, revenue, data, goodwill, or business opportunities, even if advised of the possibility of such damages.

Nothing in these Terms excludes or limits our liability for fraud, fraudulent misrepresentation, death or personal injury caused by our negligence, or any other liability that cannot be excluded or limited under applicable law.

14. Indemnity

You agree to defend, indemnify, and hold harmless Nono (Makoto Nonoyama) from and against any claim, demand, loss, or expense (including reasonable legal fees) arising out of (a) your breach of these Terms, (b) your misuse of Tayu, or (c) your violation of any law or the rights of a third party in connection with your use of Tayu.

15. Termination

You may stop using Tayu at any time. We may suspend or terminate your access to paid features if you materially breach these Terms, fail to pay amounts owed, or use Tayu in a way that exposes us to legal or financial risk. If we terminate your paid plan without your fault, we will refund the unused portion of any prepaid fees on a pro-rata basis. Sections 9 (Intellectual property), 11 (Export controls), 12 (Disclaimers), 13 (Limitation of liability), 14 (Indemnity), and 17 (Governing law) survive termination.

16. Changes to these Terms

We may update these Terms from time to time. If a change is material, we will update the “Last updated” date at the top of this page and, where appropriate, notify paying customers by email at least 14 days before the change takes effect. Your continued use of Tayu after the effective date constitutes acceptance of the updated Terms.

17. Governing law and venue

These Terms are governed by the laws of Japan, without regard to its conflict-of-laws rules. You and we agree that the Tokyo District Court (東京地方裁判所) will have exclusive jurisdiction over any dispute arising out of or relating to these Terms or Tayu, except where mandatory consumer-protection rules of your country of residence give you the right to bring a claim in a local court — in which case those rules apply.

18. General

These Terms, together with the Privacy Policy and Refund Policy, constitute the entire agreement between you and us regarding Tayu and supersede any prior agreement on the same subject. If any provision is held unenforceable, the remaining provisions will continue in full force. Our failure to enforce any right or provision will not be a waiver of that right or provision. You may not assign these Terms without our prior written consent; we may assign them in connection with a sale or restructuring of our business.

19. Contact

The Operator of Tayu is Nono (legal name: Makoto Nonoyama / 野々山諒), a sole proprietor based in Japan. Questions about these Terms can be sent to support@tayutau.app.
