Harumung Privacy Policy

Effective: October 30, 2026

90ms (“we”) respects the privacy of everyone who uses the Android and iOS app Harumung (the “app”). This policy explains what information the app handles, where it stays and how it is used.

1. Information we collect

The app has no sign-up or login, and we run no server that receives your information. Your records, special days, memos, daily reviews, pet and garden data and settings are stored only on your device and are never sent to us. We do not view, keep or share them.

The one exception: when the app crashes, the following crash report reaches us through Google’s Firebase Crashlytics so we can find and fix the cause. It never includes the records, memos or other content you enter.

2. Ads and third-party services (Google AdMob)

The app is free and shows ads from Google AdMob. To serve and measure ads, Google may collect and process:

Users in the European Economic Area, the UK, Switzerland and certain US states are asked for their choice through Google’s User Messaging Platform before any ad is requested. You can change that choice at any time in My records › Settings › Ad privacy choices. On Android you can also reset or delete your advertising ID in your device settings.

On iOS, the app asks for your permission through Apple’s App Tracking Transparency prompt before the IDFA can be used. Only if you allow it is the IDFA passed to Google, where it may be combined with information from other companies’ apps and websites for personalized ads and ad measurement (the App Store lists this as “Data Used to Track You”). Every feature works the same if you don’t allow it, and you can change your choice any time in Settings › Privacy & Security › Tracking on your iPhone or iPad.

See the Google Privacy Policy and How Google uses information from sites or apps that use its services.

3. Device permissions

4. Backups

5. Retention and deletion

App data is removed from your device when you delete it in the app or uninstall the app. Because we keep no user data, there is nothing for us to delete. Crash reports from section 1 are kept in Firebase for 90 days and then deleted. Information Google processes for ads is retained under Google’s policies.

6. Sharing

We do not share your personal information with third parties. Crash reports (section 1) are processed for us by Google LLC’s Firebase Crashlytics; when a crash happens they are sent over the network to Google’s servers, which may be in the United States or other countries, and kept for 90 days. Google also collects and processes information directly through the ad SDK in the app, as described in section 2, and it may be transferred to Google’s servers outside your country. In Google Play’s Data safety section, this information the ad SDK sends to Google is listed as “shared”, and in the App Store’s App Privacy section it is listed as data collected (with the device ID used to track you).

7. Children

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

8. Your rights

All app data stays on your device, so you can view, edit and delete it directly in the app. You can change your ad choices as described in section 2. If you have questions, contact us below.

10. Our website

The Harumung website (harumung.app) uses Cloudflare Web Analytics to count visits and see where visitors come from. It uses no cookies and collects no personally identifying information; Cloudflare counts only visit statistics such as the page address, the referring page, country, and browser and device type. The website has no ads, sign-up or forms that send information, and its demos (checking off to-dos, counting days) run only in your browser. Your entries in the app are not part of these statistics. Cloudflare handles this data under the Cloudflare Privacy Policy.

11. Changes

If this policy changes, we will post the new version on this page with its effective date. If the app adds features such as accounts or server backup that change what is collected, we will update this policy before those features are offered.
