Effective date: 26 October 2026

These Terms of Use (the "Terms") are a binding agreement between you and ZENOPCB ELECTRONICS TECHNOLOGY COMPANY LIMITED ("ZenoPCB", "we", "us", "our"). They govern your access to and use of our websites, our web, mobile and desktop applications (each an "App"), and the online services, features, content and connected devices that work with them (together, the "Service").

By downloading, installing, accessing or using the Service, or by creating an account, you confirm that you have read, understood and agree to these Terms and our Privacy Policy. If you do not agree, do not use the Service.

If you buy a subscription, it renews automatically until you cancel it, as explained in Section 8. Section 19 explains how disputes are resolved.

If a particular App has additional terms, those terms form part of these Terms for that App and prevail if they conflict with these Terms.

1. The Service

ZenoPCB develops and operates a range of Apps and online services, which may include tools for creating and editing content, AI-powered features, and applications for setting up, monitoring and controlling connected devices. The features available depend on the App, the version you use, your device, your country and whether you have a paid subscription.

2. Eligibility

You must be at least 16 years old, or the minimum age required in your country to use the Service without parental consent if that is higher, to use the Service. If you are under the age of legal majority where you live, you may use the Service only with the involvement and consent of a parent or legal guardian, who agrees to these Terms on your behalf. If you use the Service on behalf of a company or other organisation, you confirm that you have authority to bind that organisation to these Terms, and "you" includes that organisation.

3. Your Account

Some features require an account. When you create one, you agree to provide accurate and complete information and keep it up to date. You are responsible for keeping your login details confidential and for all activity under your account. Tell us immediately at [email protected] if you suspect unauthorised use of your account.

You may not create an account using false information or on behalf of someone else without permission, or create a new account after we have suspended or terminated your previous one for breaching these Terms. We may refuse or reclaim a username, for example if it infringes someone else's rights or is misleading or offensive.

You may have only one account per App at a time unless we allow otherwise. You must not share your account with others or let others use your login details.

Equipment and connection. You are responsible for providing a compatible device, operating system and internet connection to use the Service, and for any data, mobile or internet charges you incur.

You can delete your account at any time as described in our Privacy Policy.

4. Licence to Use the Apps

Subject to your compliance with these Terms, ZenoPCB grants you a personal, limited, non-exclusive, non-transferable, non-sublicensable and revocable licence to download, install and use the Apps on devices that you own or control, for your own personal use or, where an App is designed for business use, for your internal business purposes.

The Apps are licensed, not sold, to you. ZenoPCB and its licensors keep all rights not expressly granted to you in these Terms. Some parts of the Apps may include open source software, which is licensed to you under its own licence terms; where those terms conflict with these Terms, the open source licence applies to that software.

5. Acceptable Use

When using the Service, you agree not to:

• copy, sell, rent, lease, sublicense, distribute or otherwise commercially exploit the Service or any part of it, except as these Terms allow;
• modify, translate, adapt or create derivative works of the Service, or decompile, disassemble or reverse engineer it, except where the law expressly allows this despite this restriction;
• bypass, disable or interfere with any security feature, licence check, usage limit or paywall;
• access the Service by automated means, such as bots, scrapers or crawlers, or extract data from it, without our written permission;
• upload or spread viruses, malware or other harmful code;
• overload, disrupt or damage our servers, networks or systems, or attempt to gain unauthorised access to them or to other users' accounts;
• use the Service to break any law, or to infringe the intellectual property, privacy or other rights of anyone;
• use the Service to create, upload or share content that is illegal, harmful, threatening, abusive, harassing, defamatory, obscene, hateful, misleading or fraudulent, or that sexually exploits or endangers children;
• use AI Features to impersonate real people, create deceptive "deepfakes", or edit images of people without their permission in a way that could harm them;
• remove, hide or alter any copyright, trademark or other proprietary notice;
• use the Service to build a competing product or service, or to train or improve any AI model; or
• help or encourage anyone else to do any of these things.

6. Your Content

"Your Content" means any photos, videos, audio, text, files, data and other material that you create, upload, import, store or share through the Service, including results produced by AI Features from your input.

Ownership. You keep all ownership rights you have in Your Content. ZenoPCB does not claim ownership of it.

Licence to us. You give ZenoPCB a worldwide, non-exclusive, royalty-free licence to host, store, copy, process, transmit and display Your Content only as needed to operate, provide, secure and improve the Service for you, for example to save your projects, sync them between devices, or process them with AI Features. This licence ends when you delete Your Content or your account, except for copies we must keep by law or that remain for a short time in backups. We do not use Your Content to train AI models unless you clearly agree to this.

Your responsibility. You are solely responsible for Your Content. You confirm that you own it or have all the rights and permissions needed to use it in the Service, including permission from any person who appears in it, and that it does not break these Terms or any law.

Shared and public content. If an App lets you share content publicly or with other users, others may be able to view, copy or share it. We may remove or restrict access to any content that we reasonably believe breaks these Terms or the law, and we may report illegal content to the authorities.

Backups. Although we take care to protect Your Content, we recommend that you keep your own copies of anything important. We are not responsible for loss of content, except as provided in Section 15.

7. AI Features

Some Apps include features that use artificial intelligence to generate, edit, analyse or transform content ("AI Features"). When you use them, you understand that:

• results are generated automatically and may be inaccurate, incomplete, unexpected or similar to results produced for other users;
• you should review results before relying on them, and must not rely on them for medical, legal, financial, safety or other professional decisions;
• you are responsible for how you use results, including making sure your use does not infringe anyone's rights or break any law;
• we may apply safety filters, and may refuse or limit requests that we reasonably believe are harmful or break these Terms; and
• usage of some AI Features may be limited by daily or monthly quotas, which may vary by subscription plan.

8. Subscriptions and Purchases

8.1 Paid features. Some features are available only with a paid subscription or one-time purchase. Prices, features and billing periods are shown in the App before you buy and may vary by country.

8.2 Purchases through app stores. If you buy through the Apple App Store, Google Play or another app store, the purchase is processed by that store, and its terms and payment policies apply to the payment, including billing, cancellation and refunds. Your payment is charged to your store account when you confirm the purchase.

8.3 Automatic renewal. Subscriptions renew automatically at the end of each billing period for the same length of time, at the then-current price, unless you cancel at least 24 hours before the end of the current period. Your store account will be charged for renewal within 24 hours before the current period ends.

8.4 How to cancel. You can manage or cancel a subscription at any time in your store account settings: on iOS, in Settings > your name > Subscriptions; on Android, in Google Play > Payments & subscriptions > Subscriptions. Deleting an App or your account does not cancel your subscription. After cancelling, you keep access to paid features until the end of the period you have already paid for.

8.5 Free trials. If we offer a free trial, any unused portion is forfeited when you buy a subscription. Unless you cancel at least 24 hours before the trial ends, the trial converts into a paid subscription and you will be charged.

8.6 Price changes. We may change subscription prices. We will tell you in advance, as required by the app store and applicable law, and the new price will apply from your next renewal. If you do not agree, you can cancel before the renewal.

8.7 Refunds. Except where the law requires otherwise, payments are non-refundable and we do not give partial refunds for unused time. For purchases made through an app store, refund requests must be made to that store under its refund policy; we cannot issue refunds for those purchases ourselves.

8.8 Direct purchases. If you buy directly from us, for example on our website, you agree to pay the fees shown at checkout and authorise us and our payment provider to charge your chosen payment method. Any additional terms shown at checkout also apply.

8.9 Taxes. Prices may include or exclude taxes depending on your country and how you buy. You are responsible for any taxes that apply to your purchase and that are not collected by us or the app store.

8.10 Failed payments. If a renewal payment cannot be collected, for example because your payment method has expired, the app store may retry the charge for a period and may give you a grace period during which you keep access to paid features. If payment is still not received, your access to paid features may be suspended until payment is made or the subscription is cancelled.

8.11 Promotions and discounts. We may offer introductory prices, discounts or promotional codes. Each offer is subject to the conditions shown with it, cannot be combined with other offers unless stated, has no cash value and may end at any time. After a promotional period, the subscription renews at the regular price unless you cancel.

8.12 Family Sharing and multiple devices. Whether a purchase can be shared with family members or used on several devices depends on the App and the app store's rules, and is shown in the App's store listing.

8.13 Virtual items. If an App offers credits, tokens or other virtual items, they have no cash value, cannot be exchanged for money, transferred or resold, and may expire as stated in the App, except where the law requires otherwise.

9. Advertising

Free versions of some Apps show ads, which may be provided by third-party advertising networks. Your interactions with advertisers, including any purchase, are solely between you and the advertiser. How advertising partners use information is explained in our Privacy Policy.

10. Third-Party Services

The Service may include or link to services, content or features provided by others, such as sign-in providers, cloud storage, maps, social networks or AI service providers. Your use of them is governed by their own terms and privacy policies. We do not control them and are not responsible for their content, availability or practices.

Third-party materials. Some content available in the Service, such as fonts, stickers, music, images, templates or data, may be provided by third parties under licence. You may use these materials only within the Service and as permitted by these Terms, and not separately from the content you create with them. We cannot review all third-party materials and you access them at your own risk.

11. Connected Devices

If you use an App with connected hardware, such as sensors, controllers or other smart devices, you are responsible for installing, powering, connecting and using that hardware correctly and safely, following its manual and all applicable laws and electrical and safety standards. Remote monitoring and control depend on power, network connections and third-party services, which can fail or be delayed. The Service is not designed or intended for emergency response, life support, medical, or safety-critical uses where a failure or delay could lead to death, injury, or serious property or environmental damage, and you must not rely on it as the only means of protection in such situations. Hardware sold separately is covered by its own warranty terms.

12. Our Intellectual Property

The Service, including its software, design, text, graphics, logos, icons, sounds, templates, effects and other content provided by us, and the ZenoPCB name and trademarks, are owned by ZenoPCB or its licensors and are protected by intellectual property laws. Except for the licence in Section 4, these Terms do not give you any rights in them. You may not use our trademarks without our prior written permission.

Feedback. If you send us ideas, suggestions or feedback, you agree that we may use them freely, without any obligation or payment to you.

Copyright complaints. If you believe content in the Service infringes your copyright, please send a notice to [email protected] identifying the work, the infringing material and where it is located, your contact details, and a statement that your notice is accurate and that you are the owner or authorised to act for the owner.

13. Updates and Changes to the Service

We continually improve the Service. We may release updates, which may be installed automatically depending on your device settings, and some features may require the latest version. We may add, change or remove features, or stop offering an App, at any time. If we discontinue a paid feature during a period you have paid for directly to us, we will offer a pro-rata refund or a reasonable alternative, unless the law requires otherwise. You may need to update your device's operating system to keep using some Apps.

We aim to keep the Service available, but it may sometimes be interrupted for maintenance, upgrades, network problems or reasons beyond our control.

Beta and preview features. We may offer features or Apps labelled as beta, preview or experimental. They are provided for testing and feedback, may contain errors, may change or be withdrawn at any time, and must not be relied on for important work.

Support. We provide support by email and, where available, through in-app help. We will make reasonable efforts to respond, but response times are not guaranteed unless stated in a separate agreement.

14. Violations, Suspension and Termination

14.1 Termination by you. You may stop using the Service and delete your account at any time. Deleting your account does not cancel a subscription purchased through an app store; see Section 8.4.

14.2 Investigations. If we become aware of a possible breach of these Terms, we may investigate it. If we believe that illegal activity has taken place, we may report it to and cooperate with the competent authorities. To the extent permitted by law, we may disclose information, including Your Content, where we believe it is necessary to comply with the law or a lawful request, enforce these Terms, respond to claims that content infringes the rights of others, or protect the rights, property or safety of ZenoPCB, our users or the public.

14.3 Actions we may take. If we reasonably believe that you have breached these Terms, that your use of the Service creates a risk or legal exposure for us or others, or if the law requires it, we may take one or more of the following actions, as appropriate to the situation:

• (a) warn you, in the App or by email, that you have breached these Terms;
• (b) remove or restrict access to any of Your Content;
• (c) limit your access to certain features;
• (d) suspend or terminate your account or your subscription;
• (e) report the matter to, and cooperate with, the competent authorities; and
• (f) take any other lawful action we consider appropriate.

Where appropriate and permitted by law, we will tell you the reason for our action and give you an opportunity to fix the problem or respond. If you believe we have made a mistake, you may contact us at [email protected] and we will review the decision.

14.4 No re-registration. If we terminate your account for breaching these Terms, you must not create a new account or try to access the Service under a different name or by other means without our permission.

14.5 Effect of termination. When your account is terminated, your right to use the Service ends, and we may delete your account and Your Content as described in our Privacy Policy. If we terminate your account for a serious breach of these Terms, you are not entitled to a refund, except where the law requires otherwise. If we terminate your account for any other reason, we will refund any prepaid fees you paid directly to us for the remaining period. Sections 6, 12, 15, 16, 17, 19 and 21, and any other provisions that by their nature should continue, survive termination of these Terms.

15. Disclaimer of Warranties

To the fullest extent permitted by law, the Service is provided "as is" and "as available", without warranties of any kind, whether express or implied, including implied warranties of merchantability, fitness for a particular purpose, accuracy and non-infringement. We do not warrant that the Service will be uninterrupted, error-free, secure or free of harmful components, that results produced by the Service, including AI Features, will be accurate or reliable, or that Your Content will never be lost.

Some countries do not allow certain warranties to be excluded. In those countries, the exclusions above apply only to the extent permitted by law, and nothing in these Terms affects your statutory rights as a consumer.

16. Limitation of Liability

To the fullest extent permitted by law, ZenoPCB and its directors, employees, partners and suppliers will not be liable for any indirect, incidental, special, consequential, exemplary or punitive damages, or for any loss of profits, revenue, data, goodwill or business opportunities, arising out of or related to the Service or these Terms, even if we have been told such damages are possible.

To the fullest extent permitted by law, our total liability for all claims arising out of or related to the Service or these Terms is limited to the greater of (a) the amount you paid us for the Service in the 12 months before the event giving rise to the claim, and (b) fifty US dollars (USD 50) or its equivalent in local currency.

Nothing in these Terms limits or excludes liability that cannot be limited or excluded by law, such as liability for death or personal injury caused by negligence, fraud, or wilful misconduct.

17. Indemnity

To the extent permitted by law, you agree to indemnify and hold harmless ZenoPCB and its directors, employees and partners from any claims, damages, losses and expenses, including reasonable legal fees, arising out of Your Content, your misuse of the Service, or your breach of these Terms or of anyone else's rights.

18. Apple App Store and Google Play

If you downloaded an App from the Apple App Store, the following also applies to that App:

• These Terms are between you and ZenoPCB only, not Apple. ZenoPCB, not Apple, is solely responsible for the App and its content.
• Your licence to use the App is limited to use on 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 provide any maintenance or support services for the App.
• If the App fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any) for the App to you. To the maximum extent permitted by law, Apple has no other warranty obligation with respect to the App.
• ZenoPCB, not Apple, is responsible for addressing any claims by you or any third party relating to the App or your use of it, including product liability claims, claims that the App fails to conform to any legal or regulatory requirement, and claims under consumer protection, privacy or similar laws.
• If a third party claims that the App or your use of it infringes their intellectual property rights, ZenoPCB, not Apple, is solely responsible for investigating, defending, settling and discharging that claim.
• You confirm 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.
• You must comply with any applicable third-party terms, such as your wireless data service agreement, when using the App.
• Apple and its subsidiaries are third-party beneficiaries of these Terms and, once you accept these Terms, Apple has the right to enforce them against you as a third-party beneficiary.

If you downloaded an App from Google Play, your use of the App is also subject to the Google Play Terms of Service. Where they conflict with these Terms in relation to your use of Google Play, the Google Play Terms of Service apply.

19. Governing Law and Dispute Resolution

These Terms are governed by the laws of the Socialist Republic of Vietnam, without regard to its conflict of law rules.

If you have a dispute with us, please contact us first at [email protected]. Most concerns can be resolved quickly this way. If a dispute cannot be resolved by negotiation within 30 days after one party notifies the other, either party may submit it to the competent court in Ho Chi Minh City, Vietnam. If both parties agree in writing, the dispute may instead be resolved by arbitration at the Vietnam International Arbitration Centre (VIAC) in Ho Chi Minh City, under its rules, in English.

If you are a consumer, nothing in this Section deprives you of the protection of mandatory laws of the country where you live, including any right to bring a claim in the courts of that country.

20. Changes to these Terms

We may update these Terms from time to time, for example to reflect changes to the Service or the law. When we do, we will update the "Last updated" date above. If the changes are material, we will notify you in the App, by email or by another appropriate method at least 15 days before they take effect, unless the changes are required urgently by law or to address security risks. If you continue to use the Service after the changes take effect, you accept the updated Terms. If you do not agree, you must stop using the Service and may delete your account.

21. General Terms

Entire agreement. These Terms, together with the Privacy Policy and any additional terms for a particular App, are the entire agreement between you and ZenoPCB about the Service and replace any earlier agreements on this subject.

Assignment. You may not assign or transfer your rights or obligations under these Terms without our prior written consent. We may assign our rights and obligations to an affiliate or in connection with a merger, acquisition or sale of assets.

Force majeure. We are not responsible for any delay or failure to perform caused by events beyond our reasonable control, such as natural disasters, epidemics, war, riots, government actions, power or internet outages, failures of third-party services, or cyberattacks.

Severability. If any provision of these Terms is found invalid or unenforceable, it will be limited to the minimum extent necessary and the rest of these Terms will remain in full effect.

No waiver. If we do not enforce a provision of these Terms, that does not mean we waive our right to enforce it later.

Electronic communications. You agree to receive notices, agreements and other communications from us electronically, in the App, by email or on our website, and that these satisfy any legal requirement that such communications be in writing.

Notices. We may send you notices by email to the address linked to your account, through the App, or by posting them on our website. A notice sent by email is treated as received when sent, even if you no longer use that address, so please keep your email address up to date. You may send notices to us by email at [email protected] or by post to the address in Section 22.

Relationship of the parties. Nothing in these Terms creates any partnership, joint venture, employment or agency relationship between you and ZenoPCB.

No third-party beneficiaries. Except as stated in Section 18 for Apple, these Terms do not give any rights to anyone other than you and ZenoPCB.

International users. The Service is operated by ZenoPCB from Vietnam and can be accessed from many countries. Some Apps, features or content may not be available in every country. If you use the Service from outside Vietnam, you are responsible for complying with the local laws that apply to you.

Headings. Section headings are for convenience only and do not affect the meaning of these Terms.

Export and sanctions. You agree to comply with all applicable export control and sanctions laws when using the Service.

Language. These Terms may be translated into other languages. If there is any conflict between the English version and a translation, the English version prevails, except where the law requires otherwise.
