"Our Aligner Log" (the "App"; called "うちのマウスピース" in Japanese) respects your privacy and works to protect personal information. This policy explains how the App handles information.
The App does not collect any personal information or usage data. Data recorded in the App, such as aligner wear times, is saved on your device and is never sent to the developer's servers (the App has no servers of its own).
The App does not provide or share any of your information with third parties.
The App lets you save your records as a file yourself and share it with other devices or apps. This sharing happens only when you do it, and the developer never collects or sends your data automatically.
Only if you set up cloud sync, your record data (mouthpiece.json) is also saved to a file in the cloud storage you choose (such as Dropbox, Google Drive, or iCloud Drive). This file is managed with your own account, and the developer cannot access it. How the data is handled in the cloud storage follows the privacy policy of each service. You can turn off cloud sync at any time from the Summary tab.
The App does not show any ads.
The App may access your device's storage to save and read records and to share or save files. This is used only to provide the App's features.
The App does not collect personal information from anyone.
This policy may be changed when needed. The changed policy takes effect when it is posted on this page.
