Last updated: October 14, 2026
In short
Costday doesn't collect any personal data. Everything you enter stays on your device.
What data the app handles
Ingredient names, pack sizes and prices, price history, recipes, portions, menu prices and your settings are stored only on your device, inside the app's own storage. They are never sent to us or to any third party.
Analytics, ads and tracking
Costday uses no analytics tools, ad networks or tracking technologies. There is no account or sign-in.
Sharing
When you export the cost report, the file goes through the iOS share sheet to the app you choose. You stay in control of what is shared and with whom.
Purchases
Costday Pro is sold by Apple through the App Store. We never receive your payment details. See Apple's privacy policy at apple.com/legal/privacy.
Deleting your data
Deleting the app removes all Costday data from your device. You can also delete ingredients and menu items inside the app.
