Overview

KitchenCost is a recipe cost calculator. This policy explains how the app handles your data.

Data Stored on Your Device

Your ingredient, menu, and price records are stored on the device you are using by default. If you choose to turn on cloud sync to work across devices, they are kept in sync storage as well. Limited usage and stability data may be processed separately, as described later in this policy. Key business data such as names, notes, prices, pack sizes, and selling prices is encrypted on your device before it is sent over a secure connection; some metadata needed to run sync and manage access, such as identifiers and change timestamps, is handled separately.

• No account required to use the app on your device
• Cloud sync is optional; turning it on also keeps these records in sync storage

Data Export

KitchenCost provides export/import via backup files in Settings. Backups are created on your device and shared only in the way you choose. You can use the app without an account; data stays local on your device by default, and sync runs only when you choose to enable it.

Usage Analytics & Error Tracking

We use PostHog Cloud (PostHog, Inc.) to collect pseudonymous usage data and error reports.

• Data collected: App usage events, screen views, crashes/errors, device type, OS version, country/region, pseudonymous analytics identifier, ingredient names entered when creating an ingredient (whitespace normalized, emails masked, limited to 80 characters), quantity, and unit
• Data NOT collected: Recipe names, prices, notes, purchase links, payment method details such as card numbers, precise location
• PostHog Cloud is hosted in the US region
• PostHog Privacy Policy: posthog.com/privacy

Subscription & Payments

Premium features are managed through RevenueCat.

• Purchases are processed by Apple/Google; the app only verifies subscription status
• Anonymous identifiers are used to manage subscription status
• Payment information (card numbers, etc.) is not handled directly by the app

Cost Sheet Migration Service (Pro)

When a Pro user requests it from “Cost sheet migration service” in the app, we send an instruction email to the address they enter, then receive and process the files and photos attached to their reply to that email.

• Information we receive: Your reply email and the files and photos you attach (cost sheets, ingredients, recipes, etc.), the email address you reply from, and the account ID shown in the instruction email
• Purpose: Used only to add ingredients and recipes to the account that made the request and to reply to you about it
• How files are handled: Files are not handed to outside vendors; the developer opens and transfers them personally. We do not publish or sell the files we receive, and we do not use them to train AI models
• Retention and deletion: Working copies are deleted within 7 days after the work is finished. Emails stay in our support inbox as a record of your inquiry; if you want them deleted, you can ask at help@kitchencost.app
• Product improvement: We only look at the format, such as column names and table layout, and do not use values such as prices, recipe contents, or business names
• Request records: To limit the number of requests, we record the account, request time, and language; we do not store the address the instruction email is sent to. Instruction emails are sent through the email delivery service Resend

Data Deletion

You can delete data in-app (including permanently deleting from Trash) or uninstall the app to remove local data.
