Privacy Policy

Effective date: [CONFIRM: EFFECTIVE DATE, e.g. January 1, 2027]

This Privacy Policy explains how Thomas R&D LLC (“Thomas R&D,” “we,” “us”) collects, uses, and shares information when you use our mobile app Parent Primer (the “App”) and this website, thomasrnd.com (together, the “Services”). We try to collect as little as possible, and we never sell your personal information.

1. Summary

• The App is designed for parents and other adults, not for children.
• Subscriptions are purchased and billed through Apple or Google. We never see or store your card details.
• We collect only what we need to run, support, and improve the App.
• Homework photos are sent to an AI service (Claude, from Anthropic) to read them. We do not store them.
• We do not sell your personal information or use it for targeted advertising.
• You can delete your account in the App at any time, or email admin@thomasrnd.com.

2. Information we collect

Information you provide

• Account. You can browse the built-in guides without an account. To get help with your own homework or make a purchase, you sign in with your email address and a one-time code. We keep your email address.
• Homework photos and questions. Photos you take or choose, and questions you type, are sent to our servers and then to Claude, an AI service from Anthropic, to read and answer them. A photo may show your child’s name, handwriting, or school. We remove location data from photos, and we do not store photos or questions on our servers or use them to train AI. We keep a one-way fingerprint of each photo so we don’t charge you twice; it can’t be turned back into the picture.
• Homework history. For your account, we keep which homework pages and topics you got help with, and recent usage counts to prevent abuse. Guides and answers are saved on your device.
• Support messages. If you email us, we receive your email address and whatever you choose to include in your message.

Information collected automatically

• Usage and diagnostic data. We record which screens open and whether actions succeed, plus server errors, so we can fix and improve the App. Usage events use a random ID made on your device, not your account, and never include photos, homework, questions, or anything about your child.
• Purchase status. We confirm purchases through Apple and RevenueCat. RevenueCat receives your purchase records and an account ID, not your name or email address.
• Website. This website does not use cookies, analytics, or third-party trackers. Our hosting provider (Cloudflare) may process standard technical data such as IP addresses in server logs for security and reliability.

We do not collect your location, contacts, or advertising identifiers, track you across other apps or websites, or show ads.

3. Subscriptions and payments

Subscriptions and other in-app purchases are sold and processed by Apple (App Store) or Google (Google Play). Your payment details are handled entirely by Apple or Google under their own privacy policies. Thomas R&D LLC does not receive or store your credit card number or other payment card details. We receive only the information needed to verify your purchase and subscription status (for example, a transaction identifier, product purchased, and renewal or expiration date).

4. How we use information

We use the information described above to:

• provide the App and unlock features included in your subscription;
• respond to support requests and communicate with you about the Services;
• understand how the App is used so we can fix bugs and improve lessons and features;
• keep the Services secure and prevent fraud or abuse; and
• comply with legal obligations.

We do not sell your personal information, share it for cross-context behavioral advertising, or use it to build advertising profiles.

5. How we share information

We share information only in these limited cases:

• Service providers that host our servers, handle sign-in, and otherwise help us run the Services, who may use the information only to provide services to us. These include:
  • Anthropic, which reads the homework photos and questions you send (privacy policy). It does not use them to train its models.
  • RevenueCat, which manages in-app purchases (privacy policy).
• Apple and Google, as needed to process purchases and subscriptions through their stores.
• Legal reasons, if required by law or to protect the rights, safety, or property of our users, the public, or Thomas R&D LLC.
• Business transfers, if Thomas R&D LLC is involved in a merger, acquisition, or sale of assets, in which case this policy will continue to apply to your information.

6. Children’s privacy

The App is intended for parents, guardians, and other adults. It is not directed to children under 13, and children are not the intended users of the App. Although the App’s subject matter is elementary school math, its content is written for adults who want to help a child learn.

We do not knowingly collect personal information from children under 13, consistent with the U.S. Children’s Online Privacy Protection Act (COPPA), and we do not ask for your child’s details. A homework photo may show a child’s name or handwriting; we use it only to help you and do not keep it. You can cover the name before taking the photo. If you believe a child under 13 has provided us with personal information, contact us at admin@thomasrnd.com and we will promptly delete it.

7. Data retention

We keep personal information only as long as needed for the purposes described in this policy — for example, while you have an account or active subscription — and as required to meet legal, tax, or accounting obligations. In particular:

• Photos and questions: not stored on our servers.
• Account data: until you delete your account.
• Usage and diagnostic data: about 90 days.

Support emails are retained for up to [CONFIRM: e.g. 2 years]. When information is no longer needed, we delete or de-identify it.

8. Your choices and data deletion

• Delete your account. In the App, tap Account on the home screen, then Delete account. This removes your account and the data we keep about it right away, and clears the App’s history on that device. Our sign-in provider may keep a deleted sign-in for up to 30 days. You can also email admin@thomasrnd.com with the subject “Data deletion request,” and we will complete it within 30 days.
• Access or correct your data. You may ask us for a copy of the personal information we hold about you, or ask us to correct it.
• Uninstalling. Deleting the App removes data stored only on your device. Deleting the App does not cancel your subscription — see our Terms of Use.

Depending on where you live (for example, Washington, California, or the European Economic Area), you may have additional rights under local law. We will honor applicable requests and will not discriminate against you for exercising your privacy rights.

9. Security

We use reasonable administrative, technical, and physical safeguards to protect information, including encryption in transit. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.

10. Where data is processed

Thomas R&D LLC is based in the United States. Information may be processed and stored in the United States or other countries where our service providers operate.

11. Changes to this policy

We may update this policy from time to time. If we make material changes, we will update the effective date above and, where appropriate, notify you in the App. Your continued use of the Services after a change means the updated policy applies.

12. Governing law

This Privacy Policy is governed by the laws of the State of Washington, United States, without regard to its conflict-of-laws rules.
