Terms of Service

Effective May 11, 2026 · Version 1.1

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, and hosting
• Anthropic Claude API — AI-powered problem generation (uploaded worksheet content is processed transiently and not retained by Anthropic beyond the API call)
• Resend — email delivery for progress reports

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, uninterrupted availability, or accuracy of AI-generated content. Numblewick does not guarantee specific learning outcomes.

12. Limitation of Liability

To the fullest extent permitted by law, Numblewick and its operators shall not be liable for any indirect, incidental, special, or consequential damages arising from your use of the Service, including but not limited to loss of data, loss of progress records, or reliance on AI-generated educational content. Our total liability shall not exceed the amount you paid for the Service in the prior 12 months (or $50 if you have paid nothing).

13. Termination

You may delete your account at any time. We reserve the right to suspend or terminate accounts that violate these Terms. Upon termination, your data will be deleted within 30 days.

14. 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.

15. Governing Law

These Terms are governed by the laws of the State of New Jersey, without regard to conflict-of-law principles.
