Terms of Service

Effective October 15, 2026 · Version 2.5

1. Agreement to Terms

Numblewick^™ (the "Service") is operated by G10 Media LLC, a California limited liability company ("G10 Media," "we," "us"). By creating an account, you ("Parent," "Guardian," "you") confirm you are at least 18 years old and agree to these Terms and our Privacy Policy. If you do not agree, do not use the Service.

2. Who May Use Numblewick

Numblewick is designed for parents and legal guardians. Only adults (18+) may register for an account. Children may only use the Service through a child profile created and managed by their parent or guardian. Children do not accept these Terms and are not parties to this agreement; full responsibility for a child's use rests with the parent or guardian who created their profile.

3. Child Accounts & Children's Privacy

• Child profiles are created only by parents and guardians. By creating a child profile, you consent on your child's behalf to the collection and use of the information described in our Privacy Policy.
• We collect a display name (first name or nickname) and grade level for each child profile, plus the child's practice activity. The first time a child signs in to the profile you created, Numblewick asks a few setup questions: their favorite animal, food, color, and TV or movie character; optionally, a favorite singer or artist; and which math topics feel hardest. Earlier versions of the app asked for the first names of friends and of brothers or sisters. We no longer ask for them or use them, and we have deleted those already stored. Later, from their own profile screen, a child can optionally add which math topics they're studying in school. We use these answers only to personalize practice (favorites appear in word problems, and the hardest topics and school topics get extra practice), and we never show them to other families. We do not collect a child's email address, phone number, home address, photo, or any other contact information.
• Children cannot register on their own; a child can only sign in to a profile a parent or guardian created.
• We comply with the Children's Online Privacy Protection Act (COPPA). If you believe a child has given us information beyond what is described here, contact us and we will delete it.
• You may review your child's profile and practice data, and delete the profile with everything associated with it, at any time from the Parent Dashboard.

4. Information We Collect from Parents

• Email address (for sign-in and the emails described in our Privacy Policy)
• First name
• State and school name (optional, to align practice to your state's standards)
• Practice data generated by your children's profiles (problems attempted, scores, topics)

We use this information only to operate the Service, keep your account secure, and send the emails described in our Privacy Policy.

5. What We Do Not Do

• We do not show advertising in the Service.
• We do not sell, rent, or license personal information about you or your children to anyone.
• We do not use a child's name, grade, practice history, or any other child-specific data for any advertising or commercial purpose.
• We do not build behavioral or advertising profiles of you or your children.
• We do not allow third parties to track you or your children across the internet from within Numblewick.
• We do not share individual practice data with schools, districts, or other institutions without your written consent.

We may use aggregated, de-identified statistics, which cannot identify any child, family, or account, only to improve the Service.

6. Data Security

We use industry-standard security measures, including encrypted transmission (TLS), authentication controls, and role-based access restrictions. No system is perfectly secure; by using the Service you accept the residual risk inherent in any internet-connected service.

7. Third-Party Services

Numblewick uses these providers, each governed by its own privacy policy:

• Google Firebase: authentication, database, file storage, and hosting
• Anthropic Claude API: AI-generated hints and worksheet-derived problems. Uploaded worksheets and prompt text are sent to Anthropic only to fulfill the immediate request. Under Anthropic's standard API terms this content is not used to train Anthropic's models, and is retained by Anthropic for up to 30 days for abuse detection and trust-and-safety review only
• Apple (App Store): membership payments. Apple processes the payment with your Apple ID; we receive only the subscription's status, dates and transaction identifiers, never card details
• Resend: email delivery (progress reports, password resets, account notices). Resend has access only to the email address and the message contents

If we add a provider that receives personal information, we will update this section and our Privacy Policy first.

8. Uploaded Worksheets

Parents may upload a photo or document of a child's schoolwork from the Parent Dashboard. Its content is sent to an AI model to generate similar practice problems. The uploaded file is deleted from our storage once it has been read, and always within 24 hours; the generated problems stay in your account until you delete them. Uploaded content is never used for advertising. You must have the right to upload anything you upload.

9. Disclaimer of Warranties

The Service is provided "as is," without warranties of any kind, express or implied, including fitness for a particular educational purpose or the accuracy of AI-generated content. We do not guarantee specific learning outcomes. Availability is addressed in Section 12.

10. Limitation of Liability

To the fullest extent permitted by law, G10 Media LLC and its members, officers and employees are not liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of or inability to use the Service, including loss of data, loss of progress records, lost educational opportunity, or reliance on AI-generated educational content.

Our total liability for all claims together is limited to the greater of (a) the total amount you paid for the Service in the 12 months before the event giving rise to the claim, or (b) US $50.

Nothing in these Terms excludes or limits liability that cannot lawfully be excluded, including liability for fraud, for death or personal injury caused by negligence, or under applicable data-protection or children's-privacy law. Some jurisdictions do not allow certain warranty exclusions or damage limits, so parts of this section may not apply to you.

11. Subscriptions, Billing and Cancellation

When memberships begin. Paid memberships start on the date we announce to families by email. Before that date, no subscription payments are taken and families can use Numblewick free. The terms below apply from that date.

The family membership. A Numblewick family membership costs $8.99 a month (or the equivalent shown in your App Store) and covers every child in your family. It includes unlimited practice for each child, worksheet uploads, and buying in the Glimmer Shop. One membership covers the whole family: every parent, co-parent and child linked to it.

Free trial. A new subscriber gets a 7-day free trial. Unless you cancel at least 24 hours before the trial ends, it becomes a paid membership at the price shown when you subscribed. Apple decides eligibility, and the trial is generally available once per Apple ID.

Buying through Apple. Memberships are bought in the Numblewick app on iPhone or iPad through Apple's App Store and paid with the payment method on your Apple ID. Apple processes the payment; we never see or store your card details. Once you subscribe, the membership works on every device in your family, including the website.

Automatic renewal. The membership renews automatically each month at the then-current price, charged to your Apple ID, unless it is canceled at least 24 hours before the end of the current period. By subscribing you authorize these recurring charges.

Canceling. You may cancel at any time, with no cancellation fee, in Settings → Apple ID → Subscriptions on your iPhone or iPad (the Parent Dashboard's Family membership screen links there). Cancellation takes effect at the end of the current period: you will not be charged again, and you keep the membership until the period you have already paid for ends.

Refunds. Refunds are handled by Apple under the App Store's policies; you can request one at reportaproblem.apple.com. If Apple refunds a payment, the membership it paid for ends.

Without a membership. Each child can take one free 5-minute quiz every week, and you keep the full Parent Dashboard. If a membership ends (canceled, expired or refunded), nothing your children have earned is taken away: their coins, characters, rooms, toys and outfits stay theirs, and they can still visit their homes. Practice returns to the free weekly quiz, and worksheet uploads and buying in the Glimmer Shop wait until a membership is active again.

Founding families. Families who used Numblewick before memberships began get the membership free for 30 days from the day memberships start. We will email you when it starts and the date it ends; after that, the membership and the free weekly quiz work as described above.

Price changes. We may change the membership price. We will give you at least 30 days' notice by email before a change affects you, and Apple will also ask for your consent where its rules require it. The new price applies only from your next billing period. If you do not accept the new price, cancel before it takes effect.

Failed payments. If a renewal payment fails, Apple retries it. During Apple's billing grace period the membership continues; if payment still cannot be taken, the membership ends and your family returns to the free weekly quiz until it is renewed.

Taxes. Apple shows and collects any applicable sales tax.

12. Service Availability

We aim to keep Numblewick available, but we do not guarantee any particular level of uptime or performance. The Service may be unavailable at times, including for maintenance, updates, technical problems, or the failure of providers we depend on. We will make reasonable efforts to restore it and to schedule planned maintenance outside typical practice hours. Unavailability does not entitle you to a refund or credit, except where the law requires one.

We may change, suspend, or discontinue features at any time. If we discontinue the Service entirely, we will give paid subscribers reasonable notice and will not charge for billing periods after it ends.

13. Termination

You may stop at any time: delete your account from the Parent Dashboard, or cancel your membership and keep using the free features.

We may suspend or end access to the Service if an account is used in breach of these Terms, unlawfully, or in a way that harms children, other users, or the Service. We will give notice first unless immediate action is needed to protect children, other users, or the Service. If we end a paid account without cause, we will not charge you for any billing period after it ends.

When an account is deleted, its data, including your children's profiles and practice history, is removed from our production systems within 40 days, as described in our Privacy Policy. Export your children's records first if you want to keep them.

14. Changes to These Terms

We may update these Terms. We will tell you by email or in-app notice at least 14 days before a material change takes effect, and the app will ask you to review and accept the updated Terms before you continue using it. If you do not accept them, you may cancel your membership and delete your account.

15. Indemnity

You agree to indemnify and hold harmless G10 Media LLC and its members, officers and employees from any claim, loss, or expense arising from your breach of these Terms, your misuse of the Service, or content you upload, including any claim that uploaded material infringes another person's rights.

16. Resolving Disputes

Talk to us first. If you have a problem, email support@numblewick.com and give us 30 days to resolve it before starting any formal proceeding.

These Terms are governed by the laws of the State of California, without regard to conflict-of-law principles. Any dispute not resolved informally will be heard exclusively in the state or federal courts located in Santa Clara County, California, and you consent to that venue. Claims must be brought within one year of the event giving rise to them, to the extent permitted by law.

17. General

• Severability. If any provision is unenforceable, the rest remains in effect.
• No waiver. Not enforcing a provision doesn't waive it.
• Assignment. You may not transfer your account. We may assign these Terms in connection with a merger, acquisition, or sale of assets, with notice to you.
• Force majeure. Neither party is liable for failure to perform due to events beyond reasonable control.
• Entire agreement. These Terms and the Privacy Policy are the whole agreement between us about the Service.
