This page explains how we handle personal information and data in our apps.
By using our apps, you agree to this Privacy Policy.
We believe that the best way to protect your privacy is to avoid collecting your information whenever possible.
For this reason, our apps are designed not to send or store your data on developer-operated servers.
By not storing your data on our servers, we aim to minimize the risk of data leaks and unauthorized access.
Your data remains under your control.
| Data | Storage Location |
|---|---|
| App data | Your device |
| When iCloud Sync is enabled | Your personal iCloud (Apple CloudKit) |
| Developer-operated servers | Not stored |
The data you create or save in our apps is stored only on your device or in your personal iCloud account.
We cannot access or view your data.
Some of our apps support iCloud synchronization using Apple CloudKit.
When enabled, your data is stored in your personal iCloud account associated with your Apple ID.
If you wish to delete your data, please delete it within the app or uninstall the app.
If iCloud Sync is enabled, uninstalling the app will not delete the data stored in your iCloud account.
If you also wish to remove your synchronized data, please delete it from your own iCloud account.
Because we do not store or manage your personal data, we cannot fulfill requests for access, correction, deletion, or data portability.
This is because your data is stored on your own device or in your personal iCloud account, not on our servers.
Some free apps display advertisements provided by Google AdMob.
For advertising purposes, Google may collect or use information such as advertising identifiers and device information. This information is used to deliver, personalize, and improve advertisements.
For more information, please see the Google Privacy Policy.
Paid apps and apps without advertisements do not display ads.
Our apps may contain links to third-party websites.
If you click on a third-party link, you will be directed to that website.
These external websites are not operated by us. Therefore, we strongly recommend reviewing their privacy policies.
We have no control over and assume no responsibility for the content, privacy policies, or practices of any third-party websites or services.
We may update this Privacy Policy from time to time to reflect changes in applicable laws or our services.
Any changes become effective immediately upon being posted on this page.
If you have any questions or suggestions regarding this Privacy Policy or our apps, please feel free to contact us at:

If you contact us, any personal information you provide, such as your name or email address, will be used only to respond to your inquiry and provide support.
We will not disclose your information to third parties without your consent, except where required by law.
