Legal

Terms of Service

Effective September 6, 2026 · Version 2.0

1. Agreement to Terms

By creating an account on Numblewick ("Service," "we," "us"), you ("Parent," "Guardian," "you") confirm you are at least 18 years old and agree to these Terms. 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 access 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 exclusively by parents/guardians.
• We collect only a display name (first name or nickname) and grade level for child profiles. We do not collect a child's email address, phone number, home address, photo, or any other personally identifiable information.
• We do not knowingly allow children to register independently or provide us with any personal information beyond what their parent enters.
• We comply with the Children's Online Privacy Protection Act (COPPA). If you believe a child has provided us with information beyond what is described here, contact us immediately and we will delete it.
• Parents may review, update, or delete their child's profile and all associated practice data at any time from the dashboard.

4. Information We Collect from Parents

We collect the following from parent/guardian accounts:

• Email address (for authentication and optional progress reports)
• First name
• State and school name (optional, for content personalization)
• Practice session data generated by child profiles (problems attempted, scores, topics)

We use this information solely to operate the Service, authenticate your account, and send reports you have explicitly requested.

5. Aggregated & Anonymous Data

By using Numblewick, you agree that we may use aggregated, anonymized, and de-identified data — statistical information that cannot be traced back to any individual child or family — to:

• Analyze platform-wide learning trends and skill gaps
• Improve our curriculum, problem sets, and algorithms
• Produce internal and external performance reports
• Support advertising and marketing activities as described in Section 6 below

"Aggregated data" means information combined across many users (e.g., "students in grade 3 score 72% on fraction problems on average") from which no individual child, family, or account can be identified. We apply industry-standard de-identification techniques before any such data is used commercially.

6. Advertising & Commercial Use of Aggregated Data

We may now or in the future use aggregated, anonymized data for commercial and advertising purposes, including:

• Audience insights: Sharing statistical reports (e.g., grade-level skill trends, geographic usage patterns) with education companies, publishers, or advertisers to inform their products or campaigns. No individual or family is identifiable in these reports.
• Contextual advertising: Displaying advertisements within the Service that are relevant to the educational context (e.g., tutoring services, school supplies) based on general platform usage patterns — not based on any individual's profile or behavior.
• Sponsored content partnerships: Partnering with education brands to feature content or offers relevant to the grade levels and topics used on the platform.
• Data licensing: Licensing anonymized, aggregated datasets to third-party researchers, curriculum developers, or education companies for analytical purposes.

Absolute limits that will never change regardless of advertising activity:

• We will never use a child's name, grade, practice history, or any other child-specific data for any advertising or commercial purpose.
• We will never sell, rent, or disclose any data that could identify an individual child or family to any advertiser, data broker, or third party.
• We will never build individual behavioral profiles for ad targeting.
• We will never allow advertisers to target users based on their children's performance data.
• Child profiles and all data associated with them are permanently excluded from any commercial data use.

Your opt-out right: If you do not want your account's anonymized, aggregated usage patterns included in commercial data activities, you may opt out at any time by emailing support@numblewick.com with the subject line "Data Opt-Out." Opting out will not affect your access to the Service. We will process opt-out requests within 30 days.

7. What We Do Not Do

• We do not sell personally identifiable information about you or your children to any third party.
• We do not build individual advertising profiles based on your or your child's specific activity.
• We do not use children's data — including their names, grades, or practice performance — for any advertising purpose.
• We do not share individual user data with schools, districts, or other institutions without your explicit written consent.
• We do not allow third-party advertisers to track individual users across the internet from within Numblewick.

8. Data Security

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

9. Third-Party Services

Numblewick uses the following third-party infrastructure providers, each governed by their own privacy policies:

• 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 solely to fulfil 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
• Resend — transactional email (progress reports, password resets). Resend has access only to the email address and the message contents

If we engage advertising partners or data licensees in the future, we will update this section to identify them and link to their privacy policies.

10. Uploaded Content

When you upload a worksheet or photo, its content is sent to an AI model to generate practice problems. Uploaded files are stored securely in your account and are only accessible to you and family members you invite. You may delete uploaded documents at any time. Uploaded content is never used for advertising purposes.

11. 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 accuracy of AI-generated content. Numblewick does not guarantee specific learning outcomes. Availability is addressed separately in Section 14.

12. Limitation of Liability

To the fullest extent permitted by law, Numblewick and its operators 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 aggregate liability for any and all claims is limited to the greater of (a) the total amount you paid us 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 or fraudulent misrepresentation, for death or personal injury caused by negligence, or under applicable data-protection law. Some jurisdictions do not allow the exclusion of certain warranties or the limitation of certain damages, so parts of this section may not apply to you.

13. Subscriptions, Billing and Cancellation

Free and paid plans. Some features of Numblewick are offered free of charge. Others require a paid subscription. The price, billing period, and what each plan includes are shown before you purchase and again on your receipt.

Automatic renewal. Paid subscriptions renew automatically at the end of each billing period at the then-current price, using the payment method on file, until you cancel. By subscribing you authorise these recurring charges.

Cancelling. You may cancel at any time from your Parent Dashboard, with no cancellation fee. Cancellation takes effect at the end of the current billing period: you will not be charged for the following period, and you keep access to paid features until the period you have already paid for ends.

Refunds. Payments are non-refundable, and we do not provide refunds or credits for partial billing periods, unused time, or periods during which you did not use the Service — except where a refund is required by applicable law. If you subscribed through the Apple App Store or Google Play, refunds are handled under that store's policies, not ours.

Statutory cancellation rights. If you are a consumer in the United Kingdom or the European Economic Area, you have a right to cancel within 14 days of purchase under consumer law. That right applies in addition to anything in this section, and nothing here limits it. To exercise it, email support@numblewick.com.

Price changes. We may change subscription prices. We will give you at least 30 days' notice by email before a change affects you, and 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 payment fails we may retry it and may suspend access to paid features until payment succeeds. We will email you before access is suspended.

Taxes. Prices may exclude applicable sales tax or VAT, which will be added where required.

14. Service Availability

We aim to keep Numblewick available, but we do not promise or guarantee any particular level of uptime, availability, or performance. The Service may be unavailable or interrupted at times, including for maintenance, updates, technical problems, or the failure of providers we depend on.

We will make reasonable efforts to restore the Service when it is unavailable, and to schedule planned maintenance outside typical practice hours where practical. We are not liable for any unavailability or interruption, and unavailability does not entitle you to a refund or credit for the affected period.

We may change, suspend, or discontinue any part of the Service, including individual 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.

15. Termination

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

We may terminate or suspend access at any time, with or without cause, and with or without notice — including if we believe an account is being used in breach of these Terms, in a way that harms other users or the Service, or unlawfully. Where we terminate a paid account without cause, we will not charge you for any billing period after termination.

On termination, your right to use the Service ends immediately. Your account data — including your children's profiles and practice history — is deleted from our production systems within 30 days. Export your children's records before deleting your account if you want to keep them.

16. Changes to These Terms

We may update these Terms, including our advertising and data use practices. We will notify you by email and/or an in-app notice at least 14 days before material changes take effect. Continued use after the effective date constitutes acceptance of the updated Terms. If you do not accept material changes to data use provisions, you may delete your account before the effective date.

17. Indemnity

You agree to indemnify and hold harmless Numblewick and its operators 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.

18. 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. Most problems are a misunderstanding or a bug, and both are faster to fix directly.

These Terms are governed by the laws of the State of New Jersey, without regard to conflict-of-law principles. Any dispute not resolved informally is subject to the exclusive jurisdiction of the state and federal courts located in New Jersey, 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.

19. 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.
