CRONCH
PRIVACY POLICY
1. About this policy
NamNamJjeopJjeop Recipe Book ("we", "us") provides the mobile application Cronch (the "App"). This policy explains what the App does and does not do with your information. It applies worldwide.
2. What the App handles
2.1 Personal data we collect — none
We do not collect personal data from users of the App. There is no sign-up, no login, and we operate no server that receives user data.
2.2 Data stored only on your device
The following is created by you inside the App. It is written to your device's local storage and is never transmitted to us or anyone else.
- Snack names, quantities, units, categories, tags, and notes
- Timestamps and dates of each log
- Snack photos and the background-removed images (stickers)
- App settings such as theme and language, and purchase status
Background removal runs entirely on your device using the operating system's own image processing. Photos are never uploaded for processing.
2.3 Device permissions
| Permission | Purpose | Required? |
|---|---|---|
| Camera | Take a photo of a snack to save with the log | Optional — you can log without a photo |
| Photo library (read) | Choose an existing photo to save with the log | Optional |
| Photo library (write) | Save a generated receipt image to your library | Optional |
Declining a permission disables only that feature; the rest of the App works normally. You can change permissions at any time in your device settings.
3. Advertising — third-party collection
The App shows Google AdMob advertising to users who have not purchased Cronch Pro. Google LLC and its advertising partners may collect and use the following. We do not collect this ourselves and we do not receive it.
- Advertising identifier (iOS IDFA, Android Advertising ID)
- Device information (model, OS version, language, screen attributes)
- Coarse location derived from IP address
- Ad impression and interaction records
We request non-personalized ads only. The App does not ask for App Tracking Transparency permission and does not use the advertising identifier to track you across other companies' apps or websites. See Google's advertising policies for details. You can reset your advertising identifier or limit ad tracking in your device settings. Purchasing Cronch Pro removes advertising entirely.
3-1. Usage Analytics — Firebase Analytics
The app uses Google Firebase Analytics (Google Analytics for Firebase) to improve the service. It collects the following. No name, contact details, or other directly identifying information is included.
- Usage statistics such as app launches, screen views, and feature use
- Device information (model, OS version, language, country)
- An app-instance identifier (a random ID assigned per installation)
This data is processed on Google LLC servers and used only to understand feature usage and improve reliability. See the Firebase Privacy documentation for details. Deleting the app stops further collection immediately.
4. Payment information
In-app purchases are processed by the Apple App Store or Google Play. Card numbers and other payment details are handled by those stores; we never collect, see, or store them. The App records only the fact that a purchase was made.
5. Retention and deletion
- Your logs and photos remain on your device until you delete them.
- Deleting the App deletes the data it created.
- Backup files (.zip) that you export yourself remain wherever you saved them — Files, a cloud drive, and so on. You control those copies.
6. Sharing and processors
We do not sell, rent, or share your personal data with third parties.
| Party | Purpose | Data involved |
|---|---|---|
| Google LLC (AdMob) | Serving and measuring in-app advertising | Advertising identifier, device info, ad interactions |
| Apple Inc. / Google LLC | In-app purchase processing | Store-account payment data (we have no access) |
7. Your rights
You can view, edit, and delete your records directly inside the App. Because the data lives only on your device, this takes effect immediately with no request process. Deleting the App erases everything. For any other privacy question, contact us using the details in section 11 and we will respond promptly.
7.1 If you are in the European Economic Area or the United Kingdom (GDPR)
We are not a controller of any personal data about you, because we receive none. For the advertising data described in section 3, Google acts as an independent controller and its legal basis, retention periods, and transfer safeguards are set out in Google's own policies linked above.
Where any of your data is processed in connection with the App, you have the rights to access, rectification, erasure, restriction, portability, and to object to processing, as well as the right to lodge a complaint with your local supervisory authority. In practice, these rights are exercised on your own device: everything the App holds is under your direct control and can be exported or destroyed by you at any time. To exercise any right against Google's advertising processing, use the controls in your device settings or contact Google directly.
7.2 If you are a California resident (CCPA / CPRA)
We do not collect personal information, so we have none to disclose, correct, or delete on request. We do not sell your personal information, and we do not share it for cross-context behavioral advertising — the App requests non-personalized ads only, as described in section 3. There is therefore no "Do Not Sell or Share My Personal Information" mechanism to provide. We do not discriminate against anyone for exercising a privacy right.
8. Children
The App is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided information through the App, contact us and we will act on it. In the Republic of Korea, the equivalent threshold is 14 years of age.
9. Security
The App is built so that user data never leaves the device. Data is stored inside the operating system's application sandbox and is protected by device-level measures such as passcode lock and full-disk encryption.
10. International transfers
Because we do not receive your data, we do not transfer it anywhere. Any international transfer relating to advertising is carried out by Google under its own safeguards.

If this policy changes, we will post the change and its effective date in the App or on this page. Changes that are unfavorable to users are announced at least 30 days before they take effect.
