Badminton Match Log — Last updated: October 8, 2026

1. Overview

Badminton Match Log is a free Android app developed by 강건한건강. It lets players record singles and doubles matches and view lifetime, partner and opponent statistics. This policy explains how information is handled.

2. Match Records

The app has no accounts or developer-operated cloud sync. Match dates, formats, scores, results, partner names and opponent names are stored on your device. These records are not uploaded to our server or automatically attached to feedback. Match recording and statistics work offline. Android system backups may retain a separate copy as explained below.

3. Google Advertising Services

The app displays Google advertisements. The advertising SDK may collect and share device identifiers, app and advertising interactions, diagnostic information and IP addresses for advertising, measurement and fraud prevention. IP addresses can be used to estimate an approximate location. Google processes this information on its servers; we may access aggregate advertising reports. Advertising data is encrypted in transit. See the Google Privacy Policy.

Where required, a consent screen lets you manage advertising choices. A Privacy choices item is available in Settings when the consent system requires it. Device advertising and privacy controls may also apply. The app does not request GPS location access.

4. Optional Tally Feedback

Settings opens a shared Tally form in your current app language. Its URL can include nine optional context fields: app identifier, app name, installed version, build number, platform, device model, operating system version, app language and entry screen. Unavailable or unused values can be blank. Match records, names, scores, advertising identifiers and user identifiers are not automatically attached.

If you submit the form, Tally stores your feedback type, message, optional reply email and the supplied context. We use feedback to improve the app, investigate problems and reply when appropriate. Do not include sensitive information in your message. Tally and its website providers may process IP addresses, browser information and cookies when the form is opened, according to their policies. See the Tally Privacy Policy.

5. Permissions

Network access is used for advertisements and feedback. The app does not request access to your camera, microphone, contacts, photos or precise location. The advertising SDK can process approximate location inferred from an IP address without a location permission.

6. Storage and Deletion

Removing a match in the app deletes its local record. Clearing app storage in Android settings or uninstalling removes local records and preferences. Android backup is enabled, so data may also be backed up according to your device and Google account settings. Uninstalling does not remove that backup copy, and reinstalling can restore data. Manage backups separately in device or Google account backup settings.

Submitted feedback is stored separately from local records. We retain feedback for as long as needed to reply and resolve the issue. Uninstalling does not delete previously submitted feedback or data held by Google services. Google and Tally apply their own retention and deletion policies. To request deletion of feedback we hold, use the Tally contact form below, state that it is a deletion request, and provide the submission date and the minimum details needed to identify it. Reply email is optional; we may need additional information to verify and process a request. Avoid unnecessary personal information.

7. Children and Policy Changes

The app is not directed at children under 13, and we do not knowingly collect their personal information. Changes to this policy will be posted here with an updated revision date.

8. Contact

For privacy questions or feedback deletion requests, use the Tally contact form. This page links to the English form. Feedback from app Settings uses your current app language.
