Your data, plainly explained

No account needed

You can use Kookbook without signing up. We don't ask for your name, and there are no Kookbook accounts yet.

What stays on your device

Your current recipe, cooking progress, ticked ingredients, timers, saved recipes, Ask Jan conversations and dietary preferences are stored in your browser's local storage. They aren't sent to us for storage and don't sync between devices. Clearing your browser data removes them.

Photos you add to a share card are processed in your browser. We never upload them.

What's sent to our providers

• Recipe requests and Ask Jan questions (the dish, servings, flair, dietary needs, equipment, ingredients you list, the current recipe and your messages) are sent from our server to our AI provider (currently OpenAI) to generate Jan's responses.
• Read aloud sends the text being read to our voice provider (ElevenLabs) to create audio.
• Newsletter: if you sign up, your email address is sent to our mailing list provider.

Please don't include personal information in recipe requests or questions.

Analytics

If analytics are enabled, we use PostHog in a cookieless mode to count anonymous product events, such as a recipe being generated or a timer starting. We don't send the text you type, your recipes or your chats to analytics.

Server logs and rate limits

To prevent abuse, our servers briefly use your IP address to limit how many requests can be made. Errors may be logged without the contents of your requests.
