What we store
Data kept to make decks reusable
Sprout Cards stores saved flashcards, generated images, audio files, and deck metadata so the same age-and-theme deck can be reused later without generating it again.
Cloud storage
Cloudflare + Gemini
Saved deck metadata and preview sessions are stored in Cloudflare KV. Images and audio are stored in Cloudflare R2. AI generation is handled through Gemini APIs.
On your device
Offline deck cache
The app stores saved decks in your browser using IndexedDB so you can reopen them offline on the same device.
Rate limiting
Basic abuse prevention
The service applies an IP-based daily generation limit to control abuse and protect free-tier costs. Reading saved decks does not use that generation quota.
Children's content
No accounts, no child profiles
Sprout Cards does not require sign-in and does not maintain personal child profiles. Inputs are limited to age range and preset themes for flashcard generation.
