Terms of Service

• “Service” means the ZOLB website, ZOLB Circuit Lab, and any other tool, feature, or product Zolb makes available under the ZOLB brand.
• “Account” means the registered user profile you create to access certain features of the Service.
• “Content” means any circuit design, project, code, or other material you create, upload, or store using the Service.

The Service is provided for personal, educational, and evaluation use. You agree to use the Service only for lawful purposes and in accordance with these Terms.

Without limiting the above, you agree not to:

• Scrape, crawl, or use automated means to access the Service in a manner that sends more request traffic than a human could reasonably generate;
• Reverse-engineer, decompile, or attempt to extract the source code of the Service, except to the extent applicable law expressly permits this despite the restriction;
• Interfere with, disrupt, or attempt to gain unauthorized access to the Service, its servers, or any account other than your own;
• Use the Service to build a competing product, or to develop or train a competing simulator or automation tool;
• Upload or transmit any Content that is unlawful, infringing, or that you do not have the right to share;
• Use the Service for any illegal purpose, or in violation of any applicable local, national, or international law or regulation.

We reserve the right to investigate and take appropriate action against anyone who, in our sole discretion, violates this section, including suspending or terminating an Account (see Section 16, Termination).

If you create an Account, you are responsible for maintaining the confidentiality of your credentials and for all activity that occurs under your Account. You agree to notify us promptly at admin@zolbtech.com if you suspect unauthorized use of your Account.

We may suspend or disable an Account, without prior notice, if we determine in good faith that it has been used in violation of these Terms, poses a security risk, or requires suspension to comply with applicable law. A suspended Account may lose access to the Service, including any active paid tier, for the duration of the suspension.

Premium simulator access can currently be purchased through our checkout flow. Payment processing is presently in test/sandbox mode, so no real charge is made regardless of the payment method you select, until we announce otherwise. VIP simulator access can be purchased once it is shown as available in the pricing section of our website. If you buy VIP while you have an active Premium plan, VIP starts immediately for the length you choose and any remaining Premium time is replaced — it is not carried over, prorated or refunded. You will be asked to confirm this before you pay. Pricing shown on this site is subject to change; the price and any applicable discount will always be confirmed to you before you complete a purchase.

A purchase grants access for a single billing period (currently 1 month, 6 months, or 1 year, depending on what you select) and does not renew automatically. Continued access after a billing period ends requires a new purchase.

Promotional/coupon codes, where applicable, are described in Section 7 below.

Saving projects.Free accounts can use the Simulator and run circuits, but cannot save new circuits or create new saved projects — this feature is reserved for Premium and VIP accounts. A Free account that saved circuits before this restriction took effect keeps read-only access to that existing work (it can still be opened, run, and deleted) but cannot be edited and re-saved, or added to, until the account upgrades. Premium accounts may save up to a fixed number of circuits at a time (shown in the Simulator’s own project manager); VIP accounts have no saved-circuit limit. We may adjust these limits from time to time as the Service grows.

All purchases of Premium, VIP, or any other paid tier are final. Zolb does not issue refunds for change of mind, partial use of a billing period, early cancellation, or general dissatisfaction with the Service.

The sole exception to this policy is a confirmed error or bug produced by our own system that results in you being charged incorrectly. Examples of this include, without limitation:

• Duplicate charges — a processing error, such as a webhook event being handled more than once, resulting in more than one charge for the same billing period.
• Charges after valid cancellation — being charged for a billing period after your access was already validly cancelled, where this is confirmed to be a system error rather than a change-of-mind request submitted after the fact.
• Incorrect amount charged — being charged an amount that does not match the price and any applicable discount confirmed to you before purchase, due to a defect in our pricing or discount logic.

These examples illustrate a single standard — a verified defect in our own billing system — and do not create a general refund window, a trial period, or a right to a refund for any other reason. We investigate every report in good faith; a refund under this section is issued only once we confirm the error actually occurred on our end.

To report a suspected billing error, contact admin@zolbtech.com with your account email and the date of the charge in question.

The same policy, with instructions on how to request a refund, is also available on our Refund Policy page.

The Service, including its software, design, text, graphics, and underlying technology, is owned by Zolb IT Solutions or its licensors and is protected by intellectual property laws. These Terms do not grant you any right, title, or interest in the Service except the limited right to use it as described here.

You retain ownership of any Content you create using the Service. By creating or storing Content, you grant Zolb a limited, non-exclusive license to host, store, reproduce, and display that Content solely as necessary to operate and provide the Service to you (for example, saving and reloading your own projects). We do not claim ownership of your Content and will not use it for any purpose beyond operating the Service without your separate permission.

These Terms are governed by the laws of the Republic of the Philippines, without regard to its conflict-of-law principles. If you are a consumer, nothing in these Terms limits any right you have under the Consumer Act of the Philippines (Republic Act No. 7394) or other applicable consumer-protection law that cannot lawfully be waived.

Before filing a claim, you agree to first contact us at admin@zolbtech.com so we can attempt to resolve the dispute informally. Any dispute that cannot be resolved informally will be subject to the exclusive jurisdiction of the proper courts of the Philippines.

• One account, one person. Each account is for one person. Sharing, lending, or borrowing an account is not allowed. It can lead to the account being limited or suspended.
• Circuits you send. You are responsible for the circuits you send. Do not send harmful or unlawful content.
• Who can use it. Shared Circuits is available to Premium and VIP subscribers only. When your subscription ends, you can no longer send circuits. Circuits you already received can still be viewed, but not edited until you renew your subscription.

• What a certificate is. A ZOLB Circuit Lab certificate shows that you completed a challenge in ZOLB Circuit Lab. It is not a degree, a license, a professional certification, or an accreditation by any government, school, or industry body. Challenges are available on the plan shown for each challenge (Premium or VIP).
• Your name. The name on a certificate must be your real name. Check the spelling before you claim, because a certificate is made with the name you confirm. If you find a mistake later, contact us and we may correct it.
• Earn it fairly. You must complete a challenge yourself. Do not cheat, share answers or solutions, use automated tools to complete it for you, or interfere with the checks. We may refuse a certificate, or revoke one, if it was earned unfairly, was issued by mistake, or the information on it is wrong. A revoked certificate shows as revoked when someone verifies it.
• Do not misuse it. Do not edit, copy, forge, or misrepresent a certificate or its verification page, and do not present a certificate as an accreditation or as more than it is.
• Verification. The verification page is the official record of a certificate; a PDF or a screenshot is not proof by itself. The certificate ID printed on the PDF can also be entered in the checker on our Certificates page, which shows only whether the certificate is valid or revoked, its title, level and date, and a partly hidden name. You can switch public verification off. While it is off, others cannot verify your certificate by link, QR code or ID. Our Privacy Policy, Section 12 explains what the verification page shows.
• Changes to challenges. We may change, replace, or retire challenges at any time. A certificate already issued stays valid unless it is revoked.
• Deleting your account. When your account is deleted, your certificates are deleted. We email you a PDF copy of each valid certificate first. These copies have no QR code and cannot be verified online.
• No guarantee. A certificate is provided as is. We do not promise that any school, employer, or other person will accept it. Sections 11 and 12 of these Terms apply to it.
