Dinumera Privacy Policy

This privacy policy describes how information is handled in Dinumera (the “App”), a certification exam countdown app for iOS, iPadOS, and macOS.

Summary: the App collects no information about you. Everything you register stays on your device and is never sent anywhere.

1. Operator

The App is developed and provided by Legiotech LLC (“we”).

Address: Shiba, Minato-ku, Tokyo, Japan

Representative: sumik

For inquiries, see the “Contact” section below.

2. Information We Collect

The App does not collect any information, personal or otherwise.

The information you register in the App (certification name, exam date, icon, and background image) is stored only on your device, in an on-device SQLite database and the App Group container. None of it is ever transmitted to any external server.

3. Purpose of Use

As stated above, we do not collect your information, so we never use it. Data stored on your device is used only on the device, solely to provide the App's features such as displaying the countdown to your exam date.

4. Network Communication

The App does not communicate with the outside world at all. No account registration is required to use it.

5. Analytics, Advertising, and Tracking

The App uses no analytics, advertising, or tracking of any kind, and includes no third-party SDKs.

6. Access to Photo Library and Files

The App accesses your photo library or files only when you choose a background image. The selected image is copied into the App's storage area on your device and is never sent anywhere.

7. Data Sharing with Widgets

Data sharing between the App and its widgets is completed entirely within the on-device App Group. No data ever leaves your device.

8. Provision to Third Parties

Because we do not collect your information, we never provide it to third parties.

9. Future Changes

We plan to add an iCloud sync feature that stores your data in your private iCloud database. When it is added, we will update this policy and announce the change.
