Bubblebook is designed for children ages 5–10. Privacy and safety are core principles. We do not collect personal information from children. There are no ads, no social features, and no accounts.
Each day, a child pops 5 bubbles to collect words. Those words are sent to an AI service (Anthropic's Claude API) to generate a short story. The story is displayed on-device and saved locally.
To generate a personalized story, we send the 5 collected words along with the child's first name, age, and character description (as entered by a parent) to an AI service (Anthropic's Claude API). This data is used solely to generate the story and is not stored on our servers. We do not send location, device identifiers, email addresses, or any other personal information.
On-device only: Stories, engagement data (pages viewed, words tapped), and session state are stored locally on the device using standard iOS storage. This data never leaves the device except for the word-to-story API call described above.
Bubblebook does not require user accounts. There is no sign-up, no login, and no personal data on our servers.
Bubblebook does not display advertisements of any kind.
Bubblebook is designed for children and complies with the Children's Online Privacy Protection Act (COPPA). We do not knowingly collect personal information from children under 13. If you believe we have inadvertently collected such information, please contact us immediately and we will delete it.
Bubblebook uses Firebase Analytics to collect anonymous usage events (such as stories generated and session duration) to improve the app. These events contain no personally identifiable information — no names, no device IDs, no advertising identifiers. Ad-related data collection is disabled. You can disable analytics by turning off the app's network access in device settings.
Bubblebook uses Apple's built-in text-to-speech to read words aloud when tapped. This processing happens entirely on-device. No audio data is sent anywhere.

Bubblebook offers auto-renewable subscriptions billed through Apple. Payment is charged to your Apple ID account. Subscriptions automatically renew unless canceled at least 24 hours before the end of the current period. You can manage or cancel subscriptions in your device's Settings > Apple ID > Subscriptions.
You can delete all locally stored data by uninstalling the app. Since the app does not collect personal information or maintain accounts, there is no user data on our servers to request or delete.
We may update this Privacy Policy from time to time. If we make material changes, we will update the "Last Updated" date at the top of this page.
