Privacy Policy & children’s data
ThinkPlay is an independent learning app for families, available worldwide in English. Parents and guardians sign in with Pi Network. Children use ThinkPlay only through a child profile created by a parent or through a paired device (Child Mode). We intentionally collect as little personal data as possible.
1. Information we collect
Parent account and Pi sign-in
- Your Pi user identifier (UID) and the username or display name provided by Pi Network.
- Your ThinkPlay display name and account preferences.
- A secure session cookie that keeps you signed in to ThinkPlay.
- We do not receive or store your Pi password, Pi wallet private key, seed phrase, or recovery phrase. Your Pi account is managed by Pi Network and is also subject to Pi Network’s own privacy policy.
Child profile
- Display name, birth month/year (to select age-ready lessons), and chosen companion.
- Learning progress: lessons completed, correct and incorrect answers, scores, XP, streaks, and time spent learning.
- Learning-session history so parents can review progress: lesson name, number of questions answered and correct answers, and start and end times. We do not store full answer histories or question content.
- “Screen copy” (on by default): while a child is learning, their choices and right/wrong results can be sent to the parent device for live viewing. This state exists only during the learning session, is not stored as content, and the child device shows “A parent is viewing this screen.”
- Parent-set time limits, quiet hours, device lock status, and, if enabled, a hashed 4-digit Parent Gate PIN. The Parent Gate PIN is separate from your Pi account and is used only on the child device.
We do not ask for a child’s address, school, gender, phone number, email address, or Pi account. ThinkPlay does not show ads and does not sell data.
Pi payments and unlocks
- When a parent unlocks an optional feature with Pi, we receive a Pi payment identifier, the purchased feature, the amount in Pi, payment status, and related timestamps.
- We use this information to confirm the payment, provide the unlock, prevent duplicate charges, and respond to support requests. Pi Network processes the payment.
- We do not receive or store card numbers, bank account details, Pi wallet private keys, seed phrases, or recovery phrases.
Devices and technical logs
- Pairing codes, device names, and session status so Child Mode can work.
- Minimal error and access logs for operations, security, and abuse prevention.
2. How we use information
- Sign you in with Pi and maintain your parent account.
- Select age-ready lessons and unlock the next lessons as progress grows.
- Show progress, streaks, and learning insights to parents.
- Apply parent-set learning limits, quiet hours, and device locks.
- Process Pi payments and provide the features you unlock.
- Provide support, protect the service, and prevent fraud or abuse.
- Comply with applicable legal obligations.
Where required by law, we rely on your consent, the performance of our agreement with you, our legitimate interests in operating and securing ThinkPlay, and legal obligations.
3. Parental consent and children
ThinkPlay is not intended for children to sign up or use on their own. By creating a child profile, you confirm that you are the child’s parent or legal guardian and that you consent to the collection and use described in this policy. Children do not need a Pi account, email, or password. You can edit or delete a child profile at any time in the app.
4. Sharing
We share data only as needed to operate ThinkPlay:
- Pi Network, for Pi sign-in and Pi payments.
- OpenAI, to generate learning insights from aggregated data such as age band, XP, streaks, and skill scores. We do not send the child’s name, contact details, or account identifiers.
- Hosting and infrastructure providers that run and secure the service.
- Authorities or other parties when required by law or necessary to protect rights and safety.
We do not sell personal data or share it for advertising.
5. Retention and deletion
Learning data is kept while the account is active. Session history is automatically deleted after 90 days. Deleting a child profile deletes that child’s learning progress. When you delete your account, we delete personal data except information we must retain under applicable law, such as payment records. You can request deletion or export of your data by emailing [email protected].
6. Security
Connections use HTTPS, Parent Gate PINs are hashed, and access to personal data is limited to operations and support staff who need it. No system is completely secure; if we discover an incident affecting personal data, we will notify affected users and authorities as required.
7. International processing
ThinkPlay serves users worldwide, and our service providers may process data in countries other than yours. Where required, we use appropriate safeguards for international transfers.
8. Your rights
- View and edit your account details and child profiles.
- Withdraw consent by deleting a child profile or requesting deletion of your account.
- Request a copy of your data or ask us to correct or delete it.
- Object to or restrict certain processing where applicable law provides this right.
- Contact us with questions or complaints about how we handle data.
9. Changes to this policy
We may update this policy as ThinkPlay changes. When changes are material, we will update the date on this page and provide notice in the app or by other appropriate means. The English version of this policy controls.
