This website

• We do not use cookies, analytics or advertising trackers.
• The calculators run entirely in your browser. The numbers you type are not sent anywhere.
• The Bento app also runs in your browser. It saves your inputs and recipes in your browser's local storage on your device, and keeps a copy of the app so it works offline. Nothing you type is sent to us. Clearing your browser data, or removing Bento from your Home Screen, deletes it.
• Voice input in Bento is optional. When you tap the microphone, your browser's speech service (from Apple or Google, depending on your device) turns your speech into text. Bento does not record or store audio. Its answers are worked out on your device, and the conversation stays on your device.
• The site is hosted on GitHub Pages. GitHub may record technical data such as IP addresses to run and protect the service, as described in the GitHub Privacy Statement.
• Links to Etsy and Pinterest take you to their sites, where their own privacy policies apply.

If you sign up for email updates, we collect only your email address, through a Google Form. We use it to send occasional emails with new free tools and pricing tips, at most once a month. The legal basis is your consent. You can unsubscribe at any time by replying "unsubscribe" or by writing to us, and we will delete your address. We never sell or share your address.
