Every story, illustration, and interaction is designed with rigorous safety standards built specifically for children.
Multiple layers of protection ensure every story is age-appropriate, positive, and enriching.
All AI-generated content passes through Google Gemini's safety filters set to the strictest level (BLOCK_LOW_AND_ABOVE) across every harm category — harassment, hate speech, sexually explicit, and dangerous content.
Beyond AI filters, we maintain a custom blocklist that catches age-inappropriate words and concepts that might slip through standard safety checks.
Every story is validated against Flesch-Kincaid reading level standards to ensure vocabulary and complexity match your child's age tier.
The AI models we use have built-in child safety protections that are always active and cannot be disabled, providing an additional safety net.
You stay in control of your child's experience at every step.
Every story is available for parent review before your child sees it. You decide what's appropriate for your family.
Children are profiles under your parent account — they never have their own login. You authenticate, then select the child profile.
Review, modify, or delete all child data at any time from your dashboard. Request complete data deletion and we'll process it within 30 days.
We go above and beyond to protect your family's data.
We fully comply with the Children's Online Privacy Protection Act. Verifiable parental consent is required before any child data is collected.
Your child's personal information is never sent to AI services. We use placeholder tokens during generation and replace them client-side.
We use Google Analytics with privacy-preserving settings. No selling data, no advertising profiles, and no personally identifiable child data is ever collected.
All data is encrypted in transit and at rest. We use Supabase with row-level security, ensuring users can only access their own family's data.
