We will take the necessary measures to prevent unauthorized access, loss, damage, falsification, or leakage of the user's personal information. These measures include maintaining a security system, establishing a management system, thoroughly educating employees, and implementing safety measures to strictly manage personal information. We also do not transmit or store any information entered by users (text, numbers, attached images) to our servers or external services. However, we may send data to iCloud provided by Apple Inc. or Google Drive provided by Google Inc. only if the user wishes to use the backup service.

Our service uses Google's Google AdMob to distribute and display advertisements. Google AdMob will provide Google with information about events when users trigger certain aspects of user properties and the ads they see. Based on this information, Google Inc. will select and display ads with content that is highly relevant to the user in apps that implement Google AdMob.
For more information about user properties and event information that may be obtained by Google, please refer to the link below.
To improve our services, we use Google's Google Firebase to measure user trends for our services. Google may set up its own IDs or read existing device IDs in order to obtain data. During such cases, we will automatically transmit information such as your IP address and the content of your operation to Google. (We will not send any letters, numbers, or images that you enter, but only the screens, buttons, etc. that you interacted with) We may use such information in our services or to understand their usage conditions.
We may outsource some of the tasks necessary to provide our services (such as customer support) to third parties. In such cases, we may entrust all or part of the personal information to the relevant subcontractors.
These subcontractors will only have access to the minimum amount of personal information necessary to perform their work on our behalf and will not use personal information beyond the scope of the subcontracted work.
We will comply with the applicable laws and regulations and thoroughly examine our contractors' eligibility. We will also establish a system to ensure that personal information is properly managed, stipulating in the relevant contracts matters concerning confidentiality and data protection.
We will retain and use personal information for the period necessary to achieve the purpose of use.
We take all possible measures for security to ensure the accuracy and safety of personal information.
