Privacy Policy

Tenshanichi

This Privacy Policy explains how Tenshanichi handles information in connection with the app and related support services.

Contents

Effective date: March 27, 2026  |  Last updated: March 27, 2026

Tenshanichi is a calendar reference app that displays auspicious days, caution days, and Rokuyo information based on traditional Japanese calendar interpretation.

1. Information we collect

The app is designed to work without account registration and does not collect personal information from ordinary in-app use. The current version reads bundled calendar data on the device to render the calendar reference content.

The app may store a language preference locally on your device so it can reopen in your selected language. In ordinary use, that preference remains on your device and is not transmitted to us through the app.

If you visit our policy or contact pages on the website, our hosting or infrastructure providers may process standard technical request data such as IP address, user agent, referrer, and request timestamps as part of normal web delivery, logging, and security operations.

If you contact us directly for support, privacy, or legal requests, we may receive the information you choose to include in your message, such as your email address and the contents of your request.

2. How we use information

We use limited information, if any, to deliver the website pages related to the app, respond to inquiries, maintain security and availability, and comply with legal obligations.

Any language preference stored by the app is used only to remember your selected app language on your device.

3. Sharing and service providers

We do not sell personal information. We do not provide app-user personal data to advertising or analytics partners for ordinary use of the app.

We may rely on service providers that host the website or process email and related communications. Those providers may process the limited data needed to deliver pages, secure infrastructure, or transmit messages on our behalf.

We may also disclose limited information when reasonably necessary to comply with law, protect rights, investigate misuse, or address security issues.

4. Retention

Because ordinary app use does not involve server-side account data or in-app personal data collection, we do not maintain app-user personal information on our servers for standard use of the app.

A language preference saved by the app remains on your device until you change it, clear app data, or remove the app.

Website technical logs and support communications may be retained for as long as reasonably necessary for security, operations, responding to the request, protecting our rights, and complying with applicable law.

5. Your choices and rights

Depending on applicable law, you may have rights to request access to, correction of, or deletion of personal information we hold about you, or to object to or limit certain processing.

To make a privacy-related request, please contact us using the contact information below. We may ask for reasonable information to verify the request before responding.

6. Children's privacy

We do not intend to knowingly collect personal information from children in violation of applicable law. If you believe personal information from a child has been provided to us improperly, please contact us so that we can review the issue.

7. Changes to this policy

We may update this Privacy Policy from time to time. Any updated version will be posted on this page with a revised effective date.
