Terms of Service

Last updated: July 7, 2026

1. Acceptance & who can agree

Short version These Terms are a legal agreement between Mesmeraiz Inc and the parent or guardian who creates a Wonderkit account. You must be 18 or older and able to enter into a contract on behalf of your family to agree to these Terms. By creating an account, adding a child profile, or otherwise using Wonderkit, you accept these Terms.

These Terms of Service (“Terms”) govern access to and use of the Wonderkit website and service at wonderkit.dev (the “Service”), operated by Mesmeraiz Inc, a Delaware C-Corporation (“Wonderkit,” “we,” “us,” or “our”).

Wonderkit is designed for use by children under the supervision and on the account of a parent or legal guardian. Only a parent or legal guardian who is at least 18 years old and legally able to enter into a binding contract may create a Wonderkit account and agree to these Terms, and they do so on their own behalf and on behalf of the children whose profiles they add to the account. Children do not, and cannot, agree to these Terms themselves.

By creating a Wonderkit account, adding a child profile, or otherwise accessing or using the Service, you represent that you meet these requirements and that you agree to be bound by these Terms and by our Privacy Policy, which is incorporated into these Terms by reference. If you do not agree, do not use the Service.

2. Accounts & eligibility

Short version The parent is the account holder and is responsible for everything that happens under the account, including their child's use. Wonderkit is currently invite-only. Keep your sign-in and any parent PIN private — you're responsible for activity under your account.

A Wonderkit account is created and held by a parent or guardian. The parent is the “account holder” for every child profile added to that account, and is responsible for all activity that occurs under the account, including activity by their child using a child profile within that account. Children do not have independent credentials and cannot create or access a Wonderkit account on their own.

Wonderkit is currently offered on an invite-only basis. Access may require an invitation or waitlist approval, and we may change, limit, or discontinue invite-only access at any time.

You are responsible for maintaining the confidentiality of your account credentials (including your sign-in email and any parent PIN you set up to gate parent-level views and actions) and for all activity that occurs under your account. Notify us promptly at privacy@wonderkit.dev if you believe your account has been accessed without authorization.

3. What Wonderkit is

Short version Wonderkit is a family creative tool: a child describes an idea, and Wonderkit's AI helps turn it into a playable creation, with a friendly “guardian” AI chat companion along the way. It's meant for family creative play — not as a general-purpose software development platform.

Wonderkit lets a child describe an idea in their own words — a game, a story, a drawing, or another interactive creation — and uses artificial intelligence to help build a working version of that idea (a “creation”). Along the way, a child can chat with Wonderkit's guardian AI companion, which is designed to be encouraging, age-appropriate, and safety-aware.

Wonderkit is intended as a family creative tool for children to explore ideas and make things, under the supervision and account of a parent. It is not intended, and should not be relied on, as a general-purpose software development, hosting, or production platform.

4. Acceptable use / community rules

Short version Keep it kind and keep it safe: no hateful, sexual, violent, or otherwise harmful content; don't try to break or bypass Wonderkit's safety systems; be respectful to others; never share personal information (yours or anyone else's); don't use Wonderkit for anything illegal; and parents are responsible for supervising how their child uses the Service.

When using Wonderkit, you (and any child using your account) agree not to:

Because Wonderkit is used by children, the parent who holds the account is responsible for supervising their child's use of the Service and for helping their child understand and follow these community rules.

5. User content & creations

Short version Your family's ideas and creations are yours. To make Wonderkit work, you give us permission to host, process (including by sending content to AI providers), display, and moderate that content as part of running the Service. Sharing beyond your family — direct links or the Community Feed — is off by default and only happens if a parent turns it on. We may moderate, flag, or remove content that violates these Terms, and we don't promise to store creations forever.

As between you and Wonderkit, your family owns the ideas, prompts, chat messages, and creations (“user content”) that a parent or child creates using the Service.

To operate the Service, you grant Wonderkit a non-exclusive, worldwide, royalty-free license to host, store, reproduce, process (including by transmitting relevant content to our third-party AI providers so they can generate a chat response or a creation), display, and operate on your user content, solely as needed to provide, maintain, secure, and moderate the Service for you. This license also lets us moderate, flag, or take down content that violates these Terms or that we believe poses a safety risk.

Sharing a creation beyond your own family account — whether through a direct share link or Wonderkit's Community Feed — is off by default and is only turned on by an affirmative choice by the parent, for a specific creation or account-wide.

We work to keep your creations available, but we do not guarantee indefinite storage of any creation, chat transcript, or other user content, and we recommend not relying on Wonderkit as your family's sole copy of anything you want to keep permanently.

6. AI-generated content

Short version Creations and chat responses are generated by third-party AI models and are provided “as is.” AI output can be inaccurate, incomplete, insecure, or just not work the way you expected, and a similar prompt from another family could produce a similar result. Your family is responsible for how you use, rely on, or share anything Wonderkit's AI generates.

Chat responses from the guardian AI and the creations built by Wonderkit's AI builder are generated using third-party artificial intelligence models (see our Privacy Policy for which providers we use). This AI-generated output is provided “as is,” without warranty of any kind.

AI-generated creations and chat responses may be inaccurate, incomplete, contain errors or bugs, behave unexpectedly, or fail to function as intended. Because AI models generate output based on patterns in a prompt, a similar idea or prompt entered by another family may result in a similar or substantially similar creation or response — Wonderkit does not guarantee that any creation is unique to your family.

Your family is responsible for reviewing, and for deciding how to use, rely on, or share, any creation or chat output generated through the Service. Wonderkit does not warrant that AI-generated creations are secure, error-free, or fit for any particular purpose, including if a creation is shared with or used by others.

7. Intellectual property

Short version Wonderkit's name, logo, software, and website are ours. Your family's content is yours, subject to the license you give us in Section 5 to operate the Service.

The Wonderkit name, logo, and other trademarks, and the Wonderkit software, website design, and underlying technology, are the property of Mesmeraiz Inc or its licensors and are protected by intellectual property laws. Nothing in these Terms grants you any right to use Wonderkit's trademarks or branding without our prior written permission.

As described in Section 5, your family retains ownership of the user content you create, subject to the license you grant us there to operate the Service.

8. Payments & subscriptions

Short version Paid plans are billed through Stripe, our payment processor. You can cancel anytime, and cancellation stops future billing. Payments are non-refundable except where required by law, and we give at least 30 days' notice before a price change.

Some Wonderkit features require a paid subscription plan. Payments and subscription billing are processed by Stripe, our payment processor, through Stripe's hosted Checkout and Customer Portal. We do not store your full payment card details ourselves; see our Privacy Policy for what billing metadata we retain.

Subscriptions renew on the billing cycle you select (e.g., monthly) until cancelled. You may cancel anytime through the Customer Portal or by contacting us; cancellation stops future billing but does not automatically entitle you to a refund for the current billing period.

Except where required by law, payments are non-refundable and we do not provide refunds or credits for partial billing periods. You can cancel at any time to stop future charges, and your plan remains active through the end of the current billing period. Prices are exclusive of applicable taxes, which you are responsible for. If we change subscription prices, we will give existing subscribers at least 30 days' notice before the change takes effect.

9. Safety, moderation & termination

Short version We use safety systems to flag concerning chat messages or creations, and we may suspend or close an account that violates these Terms or that we believe poses a risk to a child's safety. If an account is terminated, access to its data may end too.

Wonderkit uses automated and human safety moderation to flag chat messages and creations that may violate Section 4 or otherwise raise a child-safety concern. Flagged content may be reviewed, restricted, or removed.

We may suspend or terminate an account, or restrict access to particular features, at any time and without advance notice, if we reasonably believe the account has violated these Terms, has been used in a way that endangers a child's safety, or otherwise poses a risk to Wonderkit, its users, or others. Where practical, we will try to notify the account's parent of the reason for the action.

If your account is terminated, your right to access the Service ends, and we may delete or retain your account's data in accordance with our Privacy Policy. Sections of these Terms that by their nature should survive termination (including Section 5, Section 6, Section 10, Section 11, and Section 12) will continue to apply.

10. Disclaimers & limitation of liability

Short version Wonderkit, including anything its AI generates, is provided “as is,” without warranties. Wonderkit is a creative tool, not a substitute for parental supervision. Our total liability to you is limited, though the exact cap and structure still need attorney review.

THE SERVICE, INCLUDING ALL CHAT RESPONSES AND CREATIONS GENERATED BY OUR AI PROVIDERS, IS PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, OR NON-INFRINGEMENT, AND WITHOUT ANY WARRANTY THAT AI-GENERATED CONTENT WILL BE ACCURATE, SAFE, SECURE, UNINTERRUPTED, OR ERROR-FREE.

Wonderkit's safety systems and guardian AI are designed to help reduce risk, but they are not a substitute for a parent's own judgment and supervision of their child's use of the Service. Parents remain responsible for supervising their child's use of Wonderkit.

To the maximum extent permitted by law, Wonderkit's total liability arising out of or relating to these Terms or the Service will not exceed the greater of the amount you paid to Wonderkit in the twelve months before the event giving rise to the claim, or US$100. To the maximum extent permitted by law, Wonderkit will not be liable for any indirect, incidental, special, consequential, or punitive damages.

Nothing in these Terms limits or excludes any liability that cannot be limited or excluded under applicable law, including liability for death or personal injury caused by negligence, fraud, or willful misconduct. Some jurisdictions do not allow the exclusion or limitation of certain warranties or damages, so some of the above limitations may not apply to you.

11. Indemnification

Short version You may be asked to cover our costs if your family's misuse of Wonderkit causes a claim against us — but not for claims arising from our own conduct or our AI's output.

You agree to defend, indemnify, and hold harmless Mesmeraiz Inc from claims, damages, and expenses (including reasonable attorneys' fees) arising from your or your child's misuse of the Service, violation of these Terms, or violation of applicable law. This does not apply to claims arising from Wonderkit's own negligence or willful misconduct, or from the AI-generated content our Service produces.

12. Governing law & disputes

Short version These Terms are governed by Delaware law. We'd like to resolve any disagreement informally first; if we can't, disputes go to the Delaware courts. We don't require arbitration.

These Terms, and any dispute arising out of or relating to them or the Service, are governed by the laws of the State of Delaware, without regard to its conflict-of-laws principles.

Before filing a formal claim, we ask that you first contact us at privacy@wonderkit.dev so we can try to resolve the issue informally.

If we cannot resolve a dispute informally, it will be handled by the state or federal courts located in the State of Delaware, and you and Wonderkit consent to the personal jurisdiction and venue of those courts. These Terms do not require binding arbitration and do not waive your right to bring a claim in court. Nothing here limits any mandatory consumer protections available to you under the laws of your home state.

13. Changes to these terms

Short version If we make a material change to these Terms, we'll let parents know before it takes effect.

We may update these Terms from time to time. If we make a material change, we will notify parents (for example, by email or an in-app notice) before the change takes effect. The “Last updated” date at the top of this page reflects the most recent revision. Continued use of the Service after a change takes effect constitutes acceptance of the updated Terms.
