Kobak Health Privacy Policy

Effective date: November 7, 2026

CodeNVision ("we") provides the mobile app "Kobak Health" (Korean "꼬박건강", Japanese "こつこつ健康", the "App"). The App has no sign-up or login, and we do not collect your name, email address or phone number.

Your blood sugar, blood pressure and pulse records and notes, your medicines' names, doses, photos, times, dose history and pill counts, your targets and the App's settings are stored only on your device. They are never sent to our servers and are never used for ads or usage statistics. We cannot see your health information.

This information is also excluded from Android's automatic backup (Google Drive). It leaves your device only when you create a PDF report, backup file or CSV file and choose to share it, and only to the app you pick (messaging, email, a drive, printing). From there, that app's policy applies.

Advertising ID, device information (model, OS version, language), IP address, ad interactions — collected by Google AdMob, for showing ads, measuring ad performance and preventing fraud. The App requests non-personalized ads only, and your health information is never used for ads. Ads appear only at the bottom of the records, medicines and stats screens, and not at all after you buy "Remove ads".

Payment information — handled by Google Play, for the one-time "Remove ads" purchase. Google Play processes your card and payment details; we never receive them. The App stores only whether the purchase was made, on your device.

We do not use any analytics tools.

We use services from Google LLC (AdMob, Google Play billing), which collect and process the data in section 2. See the Google Privacy Policy (https://policies.google.com/privacy) and How Google uses information from sites or apps that use its services (https://policies.google.com/technologies/partner-sites).

The advertising and payment data in section 2 may be transferred to and stored on Google servers in the United States over encrypted connections. The health information in section 1 is not transferred anywhere.

Data on your device is deleted when you delete it in the App or uninstall the App. Data collected by Google is kept according to Google's retention policies.

The App uses notifications (medicine reminders), exact alarms (if you allow them, so reminders arrive on time), boot completed (to set reminders again after a restart), vibration, biometrics (if you turn on the app lock; your phone checks your fingerprint or face and the App receives only the result) and internet (ads and purchases).

A medicine photo is stored in the App only when you pick it yourself from your phone's photo picker or camera. The App does not ask for location, contacts, microphone, camera or storage permissions.

Users in the EEA, UK, Switzerland and some US states can change their consent at any time in Settings → Ad privacy choices in the App.

You can reset or delete your advertising ID in your Android device's Settings → Privacy → Ads.

Depending on where you live (for example under the GDPR, UK GDPR or US state privacy laws such as the CCPA), you may have rights to access, correct, delete or restrict the use of your data, and to opt out of the "sale" or "sharing" of personal information for targeted advertising. We do not hold any personal data or health information that identifies you, so there is nothing for us to access or delete. You can delete the data on your device in the App or by uninstalling it, and manage the advertising data collected by Google by resetting or deleting your advertising ID as described above and through your ad privacy choices. For other questions, contact us.

The App is not directed to children under 13, and we do not knowingly collect personal information from children.

Health information is stored only on your device, and you can turn on the app lock (biometrics or your screen lock), which also hides values on home screen widgets. Because backup files contain health information, the App says so before exporting one. All network transmissions use encrypted connections (HTTPS/TLS). We do not operate our own database of personal information.
