Terms of Service

Last updated: 6 November 2026

These terms apply to the Lunaya app (the "app") on iPhone, iPad, Apple Watch and Android. By installing or using the app you agree to them. How your data is handled is described in the Privacy Policy, which is part of these terms.

What the app is

Lunaya is a Vietnamese lunar calendar with a daily sheet, events, tasks, reminders, reference tools, a family tree and appearance themes. Most features work on your device without an account.

Your account

Signing in with Google or Apple is optional and only used to back up and sync your data. You are responsible for what you enter and for keeping your sign-in secure. You can delete your account and the data on our server at any time: Settings → Account, or the page Delete your account.

Your content

The events, tasks, notes, prayers, family tree and other items you enter belong to you. You grant us only the permission needed to store them for your backup and sync, and to send the text of an item to the AI service when you tap an AI button.

Calendar information

Dates, lunar calendar data, auspicious days and similar content are reference information, provided in good faith. Do not rely on them alone for decisions about health, money, law or safety. AI suggestions can be wrong; check them before you use them.

Support the developer

Settings → Support the developer offers a one-time purchase handled by the App Store or Google Play under their own terms, including refunds. Supporting unlocks nothing: every feature is free for everyone.

Acceptable use

Do not misuse the app: do not try to break or overload our server, bypass its limits, extract the app's data in bulk, or use the AI features to produce unlawful or harmful content.

No warranty and limit of liability

The app is provided "as is", without warranty of any kind. To the extent the law allows, we are not liable for indirect or consequential loss, or for loss of data you did not back up. Nothing in these terms limits rights that the law gives you as a consumer and that cannot be limited.

Changes

If these terms change, the date at the top changes with it. Significant changes will be announced in the app. Using the app after a change means you accept the new terms.
