PRIVACY POLICY — CookClass
Last updated: May 28, 2026
This Privacy Policy explains how CookClass ("the App", "we", "our") handles your
information. Please read this policy carefully before using the App.
---
1. OVERVIEW
CookClass is a fully offline application designed for cooking instructors to manage
students, courses, schedules, recipes, payments, and expenses. The App does not
require an internet connection and does not have a backend server.
---
2. INFORMATION WE COLLECT
The App does NOT collect, transmit, or share any personal information with us or
any third party.
All data you enter into the App — including student names, contact details, course
information, payment records, recipes, photos, and expenses — is stored exclusively
on your device's local storage.
We do not have access to any data you enter into the App.
---
3. DATA STORAGE AND RETENTION
All data is stored locally on your device using an on-device SQLite database and
your device's internal file storage. No data is uploaded to any external server,
cloud service, or third party.
DATA RETENTION:
Your data remains on your device for as long as you use the App or until you
choose to delete it. The App does not automatically delete any data.
HOW LONG IS DATA KEPT:
Data is retained indefinitely on your device until you manually delete it using
the features provided in the App, or until you uninstall the App.
---
4. HOW TO DELETE YOUR DATA
You have full control over your data. You can delete your data in the following ways:
a) DELETE INDIVIDUAL RECORDS:
Within the App, you can delete any student, course, schedule, attendance record,
recipe, payment, or expense at any time by using the delete option available
in each section.
b) DELETE ALL DATA:
To remove all data stored by the App, uninstall the App from your device.
Uninstalling the App will permanently delete the local database and all photos
stored by the App.
c) RESTORE FROM BACKUP:
If you have created a backup (ZIP file), deleting that file from your device or
cloud storage will remove that backup permanently.
There is no account to delete, and no data is held on any server, so no request
to an external party is needed to delete your data.
---
5. PHOTOS AND MEDIA
When you add photos to student profiles, courses, or recipes, the App copies those
images into the App's private local storage on your device. These photos are not
shared with anyone and are deleted when you delete the associated record or
uninstall the App.
The App requests camera and photo library permissions solely for the purpose of
letting you select or capture photos within the App.
---
6. ADVERTISING
The App displays banner advertisements provided by Google AdMob. Google AdMob
may collect certain device information (such as advertising ID, device type, and
general location) to serve relevant ads. This is governed by Google's Privacy Policy:
https://policies.google.com/privacy
To opt out of personalized ads, you can adjust your device settings:
• Android: Settings → Google → Ads → Opt out of Ads Personalization
---
7. THIRD-PARTY SERVICES
The App uses the following third-party service solely for advertising:
• Google AdMob — https://admob.google.com
No other third-party services, analytics platforms, or tracking tools are used.
---
8. CHILDREN'S PRIVACY
The App is not directed at children under 13 years of age. We do not knowingly
collect personal information from children. Since all data is stored locally and
we have no access to it, no data from any user is collected by us.
---
9. BACKUP FEATURE
The App includes an optional backup feature that allows you to export all your
data as a ZIP file and share or save it to a location of your choosing (such as
your device storage, email, or a cloud service of your choice). This sharing is
performed directly by your device's operating system. We do not receive, store,
or access this backup file in any way.
---
10. CHANGES TO THIS PRIVACY POLICY
We may update this Privacy Policy from time to time. Any changes will be posted
within the App or on the App's store listing page. Continued use of the App after
changes are posted constitutes your acceptance of the updated policy.
