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.
