Terms of Service

Last updated: 31 October 2026

These Terms of Service ("Terms") govern your use of zyrro.site/ (the "Site"), operated by Zyrro ("we", "us", "our"). By accessing or using the Site, you agree to be bound by these Terms. If you do not agree with any part of these Terms, please do not use the Site.

1. Acceptance of terms

By using the Site, you confirm that you are at least 18 years old, or using the Site with the consent of a parent or guardian. We may update these Terms from time to time; the current version is always the one published on this page, and your continued use after an update means you accept the updated Terms.

2. What the Site provides

The Site provides free, browser-based seller profit calculators and related informational content for people who sell, or plan to sell, on online marketplaces such as TikTok Shop, eBay, Noon, Walmart, Etsy, and Amazon. No account or registration is required. We may add, change, or remove tools and content at any time, without prior notice.

3. Calculator results are estimates

All results produced by the calculators on the Site are estimates only. Marketplace fee structures change frequently, and the rates that apply to a given sale can depend on the product category, seller type, region, promotions, and other factors. We verify fee rates against official fee schedules when a tool is built or updated, but we cannot guarantee that a rate shown on the Site is current or correct for your particular situation. Before making any pricing, listing, or purchasing decision, always confirm the current fee rates in the marketplace’s own Seller Center or Seller Hub. Please read our Disclaimer for more detail. Nothing on the Site constitutes financial, tax, or legal advice.

4. Permitted use

You may use the Site and its calculators for your own personal or business purposes, including estimating the profitability of your marketplace sales. You may share links to the Site and to individual calculators. You may not use the Site for any unlawful purpose, or in any way that could damage, disable, or impair the Site or interfere with other users’ use of it.

5. Intellectual property

The Site, including its design, text, calculators, and other content, is owned by Zyrro or its licensors and is protected by intellectual-property laws. You may view and use the Site’s content for your own personal or business use, but you may not copy, reproduce, republish, distribute, or create derivative works from it without our prior written permission. The names, trademarks, and logos of third-party marketplaces mentioned on the Site (including TikTok, eBay, Noon, Walmart, Etsy, and Amazon) belong to their respective owners; their mention does not imply any affiliation with or endorsement by those companies.

6. User conduct

When using the Site or contacting us, you agree not to:

Submit false, misleading, or defamatory information through the contact form or any other channel.
Attempt to gain unauthorised access to the Site, its servers, or any related systems.
Introduce viruses, malicious code, or any other harmful material.
Use automated systems, such as scrapers or bots, to extract content from the Site in bulk without our permission.

We reserve the right to restrict or block access to the Site for any user who violates these Terms.

7. Third-party links

The Site may contain links to third-party websites, including marketplace Seller Center pages and official fee schedules. These links are provided for convenience only. We have no control over, and accept no responsibility for, the content, accuracy, availability, or privacy practices of third-party websites. Visiting a linked website is at your own risk, and that website’s own terms and policies will apply.

8. Limitation of liability

The Site and its calculators are provided “as is” and “as available”, without warranties of any kind, whether express or implied, including but not limited to warranties of accuracy, merchantability, fitness for a particular purpose, or non-infringement. To the maximum extent permitted by law, Zyrro and its operators shall not be liable for any direct, indirect, incidental, consequential, or special damages arising from your use of, or inability to use, the Site or its calculators — including any loss of profit, revenue, or business, or any pricing decision made on the basis of a calculator result. Your sole remedy for dissatisfaction with the Site is to stop using it.

9. Changes to the Site and these Terms

We may change, suspend, or discontinue any part of the Site at any time, with or without notice. We may also update these Terms from time to time; when we do, we will revise the “Last updated” date at the top of this page. It is your responsibility to review these Terms periodically. Your continued use of the Site after any change constitutes your acceptance of the updated Terms.

10. Governing law

These Terms are governed by, and construed in accordance with, the applicable laws of the jurisdiction in which the Site is operated, without regard to conflict-of-law principles. Any dispute arising from these Terms or your use of the Site shall be resolved under applicable law in the courts of competent jurisdiction. If any provision of these Terms is found to be unenforceable, the remaining provisions will continue in full force and effect.
