4. Analytics

We use Vercel Analytics and Vercel Speed Insights to understand how Brain Play is used and to keep the site fast.

They only collect anonymised aggregate data such as page views, general country-level location, and performance metrics.

5. Children's Privacy

Brain Play is designed for children aged 4 to 8 under parental supervision. We do not collect personal information from children, require registration, show advertising to children, share any child data with third parties, or use child data for commercial purposes.

All gameplay data is stored locally on the parent's device. Parents have full control and can delete all data at any time through the Parent Dashboard settings.

In compliance with GDPR Article 8 and COPPA, Brain Play does not process personal data of children without verifiable parental consent. Our privacy-by-design approach ensures no personal data is collected from children.

6. Legal Basis for Processing

Under GDPR Article 6, our legal basis for local data storage is legitimate interest (Article 6(1)(f)) — necessary to provide the Brain Play educational service. All processing is minimal, proportionate and necessary for providing the service.

7. Data Retention

Local device data is stored until the parent manually deletes it via Parent Dashboard settings or clears browser data. There is no automatic expiration. Vercel Analytics retains anonymised data per their own policy. No personal data is retained by Brain Play on our servers.

8. Your Rights Under GDPR

As a parent or guardian you have the right to:

• Access: request information about data we hold
• Erasure: delete all data via Parent Dashboard settings at any time
• Portability: all data is already on your device
• Rectification: update profile information directly in the app
• Objection: stop using the app at any time
• Withdraw consent: reset privacy preferences in Parent Dashboard settings

Since all data is stored locally on your device you have complete control at all times. To exercise your rights contact: brainplayy@gmail.com

9. Third Party Services

Brain Play uses Vercel for hosting and anonymous analytics. Vercel processes only anonymised aggregate data and complies with the EU-US Data Privacy Framework. No other third party services receive personal data from Brain Play.

10. Cookies and Local Storage

Brain Play does not use tracking cookies. We use browser localStorage to save game progress, privacy consent, and parental acknowledgment on your device only. This is essential for the service to function and does not track or identify individual users across websites. localStorage data stays on your device and can be cleared via browser settings or Parent Dashboard.

11. Changes to This Policy

We may update this Privacy Policy occasionally. Changes will be posted on this page with an updated date. Continued use of Brain Play after changes constitutes acceptance of the updated policy.
