Annual Diary Terms of Service
Effective Date: 2026-07-31
These Terms of Service govern your use of Annual Diary, a diary application developed and provided by Annual Diary Project.
By using Annual Diary, you agree to these Terms. If you do not agree with these Terms, please do not use the application.
1. Description of the Service
Annual Diary is a diary application that allows users to create, view, edit, and manage diary entries organized by month and day.
The application may provide the following features:
- Storage of diary text and image files on the user's device
- Synchronization of diary data with the user's Google Drive
- Recovery of diary data from Google Drive
- Conflict detection when the same diary is edited on multiple devices
- Advertisements in the standard version
- An optional ad-free subscription in applicable Android versions
- A premium version without advertisements where available
Some features may differ depending on the operating system, application version, or distribution platform.
2. User Accounts and Third-Party Services
Some cloud synchronization features require a Google Account.
When you connect Annual Diary to Google Drive, you authorize the application to access the Google Drive data necessary to provide the synchronization features. Your use of Google
Drive is also subject to Google's applicable terms and policies.
Annual Diary does not require you to create an account with the developer.
3. User Content
You retain ownership of the diary text, images, and other content that you create or store using Annual Diary.
You grant the developer a limited, non-exclusive permission to process your content only as necessary to provide the features you request, including local storage, synchronization, recovery, and conflict handling.
The developer does not claim ownership of your diary content.
You are responsible for keeping appropriate backups of important content.
4. Google Drive Synchronization
Google Drive synchronization is performed at the user's request or according to synchronization settings configured by the user.
Synchronization may fail or be delayed because of network problems, Google Drive availability, authentication problems, insufficient storage, application errors, or other circumstances outside the developer's control.
The developer does not guarantee that synchronization will always be completed successfully or immediately.
5. Paid Features and Subscriptions
Some versions of Annual Diary may offer paid features or an ad-free subscription.
Payments, billing, automatic renewal, cancellation, refunds, and eligibility are handled through the applicable application store, such as Google Play. The applicable store's terms and policies also apply.
The availability and price of paid features may differ by country, operating system, application version, and distribution platform.
6. Advertisements
The standard version of Annual Diary may display advertisements.
The premium version or an active ad-free subscription may remove advertisements as described in the relevant application store or application screen.
The developer is not responsible for the content, availability, or accuracy of advertisements provided by third-party advertising services.
7. Prohibited Use
You must not:
- Use Annual Diary in violation of applicable laws or regulations
- Attempt to interfere with or damage the application or its services
- Reverse engineer or misuse the application except where permitted by applicable law
- Use the application to store or distribute unlawful content
- Circumvent payment, access-control, or security mechanisms
- Use the application in a way that infringes the rights of others
8. Intellectual Property
Annual Diary, including its software, design, logos, names, and related materials, is owned by or licensed to the developer and is protected by applicable intellectual property laws.
These Terms grant you a limited, non-transferable right to use the application for its intended purpose. They do not transfer ownership of the application or its intellectual property to you.
9. Changes, Suspension, and Termination
The developer may update, modify, suspend, or discontinue all or part of Annual Diary when reasonably necessary.
The developer may suspend or terminate access if you materially violate these Terms, misuse the application, or create a security or legal risk.
If you stop using the application, you may disconnect Google Drive access and delete local application data from your device. Revoking Google Drive access from your Google Account is also recommended.
10. Disclaimer
Annual Diary is provided on an “as is” and “as available” basis to the extent permitted by law.
The developer does not warrant that the application will always be uninterrupted, error-free, secure, or compatible with every device or operating system.
You should maintain backups of important diary data and should not rely on Annual Diary as the only copy of important information.
11. Limitation of Liability
To the maximum extent permitted by applicable law, the developer will not be liable for indirect, incidental, special, consequential, or loss-of-data damages arising from or related to your use of Annual Diary.
Nothing in these Terms excludes or limits liability that cannot legally be excluded or limited.
12. Changes to These Terms
The developer may update these Terms when the application, services, laws, or business practices change.
The updated Terms will be published on this page with a revised effective date. Continued use of Annual Diary after the updated Terms take effect means that you accept the updated Terms.
