Otsukiai Chou / Established: August 12, 2026
These Terms define the conditions of use of the app "Otsukiai Chou" (the "App") between the user and the provider. By using the App, you are deemed to have agreed to these Terms.
The App is a tool for the user to manage records of ceremonial-occasion gifts themselves.
The amount guides, suggested return-gift deadlines, and explanations of customs shown by the App are reference values based on commonly cited information, and do not recommend or guarantee any particular etiquette. Ceremonial customs differ greatly by region, denomination, and household. Final decisions are the user's own.
Data recorded in the App is saved only inside the user's device. The provider cannot access this data and cannot restore it.
The provider is not responsible for data loss due to device loss or failure, app deletion, OS updates, or other causes. Please regularly create copies with the export feature at your own responsibility.
A passcode set with the lock feature is verified only inside the device and is not kept by the provider. If you forget the passcode, there is no way to open your records. Reissuance and unlocking on request are not possible.
To keep the App free, it may show video ads (rewarded ads) via Google AdMob. Ads are triggered by your action and do not play automatically. Ad content is determined by Google and advertisers, and the provider is not responsible for it.
Some features are offered as one-time paid features ("Pro").
1. Pro purchases and payments are handled by the App Store or Google Play.
2. Cancellations and refunds follow each store's rules; the provider cannot handle individual refunds.
3. Pro is a one-time purchase with no recurring charges.
4. To use it again after changing devices, use "Restore purchases" with the same account as at purchase.
5. The provider may change the contents of Pro features with prior notice, but will not unilaterally take away features already available to purchasers.
Storing and sharing files exported from the App (CSV, PDF, backups, etc.) is your responsibility. The provider is not responsible for handling at the sharing destination.
The password used to encrypt a backup file is not kept by the provider; if you forget it, there is no way to recover that file.
In using the App, you must not:
1. Violate laws or public order and morals
2. Decompile or reverse-engineer the App
3. Redistribute or sell copies of the App
4. Record or use others' personal information against their intent
5. Fraudulently click ads or perform automated operations that interfere with ad delivery
Except as otherwise provided by law, the provider is not liable for damages arising from use of the App.
The App assists with recording gifts and does not guarantee that return gifts are actually made. Notifications may fail to arrive depending on the device's state (power, notification settings, power-saving features, etc.).
The provider may revise these Terms as needed. Revised Terms take effect when posted on this page.
These Terms are governed by the laws of Japan. Any dispute regarding the App shall be subject to the exclusive jurisdiction of the court having jurisdiction over the provider's location as the court of first instance.
