Terms of Use

These Terms apply to everyone who uses the App. By using the App, you agree to these Terms. If you subscribe to Plus, please read these Terms before purchasing.

In addition to these Terms, the terms of the store where you got the App (the App Store or Google Play) apply to downloading the App, paying for purchases, and refunds. For the App obtained from the App Store, Apple's Licensed Application End User License Agreement (Standard EULA) applies to the license of the App.

How personal information and health data are handled is described in the Privacy Policy, and the mail-order disclosure is in the Specified Commercial Transactions page.

The App shows your calorie balance, trends, and reports based on the meals, exercise, and weight you record and the values read from Apple Health or Health Connect. Recording and basic summaries are available for free. While you are on Free, ads are shown in the App.

Plus is an optional paid plan. It adds comparisons and analyses, an expanded AI allowance beyond Free, no ads, and more. The features included in Plus are shown on the purchase screen in the App.

Features of the App may be added, changed, or discontinued for improvement or operational reasons.

Plus is sold on the App Store in Japan and Google Play in Japan. Payment is made through the store, using the payment method registered to your account on the store where you purchased. The price is shown on the store's purchase screen before you confirm the purchase.

If prices change, we will notify you following the store's procedures.

Eligible users can try Plus free for 14 days. The store determines eligibility, and it is shown on the purchase screen. Users who have already had a trial, for example, are not eligible.

To avoid being charged when the trial ends, cancel at least 24 hours before the trial ends if you purchased on the App Store, or before the trial ends if you purchased on Google Play. If you do not cancel, the price of the plan you chose is charged when the trial ends, and the paid subscription begins. The date the trial ends is shown on the purchase screen.

Unless you cancel, your Plus subscription renews automatically at each billing interval, and you are charged each time it renews.

If you switch from monthly to yearly, the yearly plan starts from the next renewal date.

If payment fails, you may lose access to Plus after the period set by the store.

Cancel from the subscription management of the store where you purchased.

• Purchased on the App Store: open your Apple Account in the iPhone Settings app and cancel from Subscriptions.
• Purchased on Google Play: cancel from Subscriptions in Google Play.

After you cancel, you can keep using Plus until the end of the period you have already paid for. Your records stay as they are after you cancel.

Because Plus is paid for through the store, please request a refund from the store where you purchased. Whether a refund is granted is decided under each store's rules.

• Purchased on the App Store: request a refund from Apple
• Purchased on Google Play: request a refund from Google Play

If you have a problem, such as being unable to use Plus because of a bug, please contact us. We will check the details and tell you what we can do.

When we confirm that the subscription is no longer valid because of a refund or revocation, Plus is no longer available.

Plus can be used only on the OS of the store where you purchased it. Plus purchased on the App Store works only on iOS, and Plus purchased on Google Play works only on Android. Plus cannot be moved to or shared with the OS of another store.

On a new device or after reinstalling the App, use Restore Purchases with the same store account you purchased with. Restoring a purchase restores only your Plus subscription, not your meal, weight, or other records. Use the App's backup to transfer your records.

The App's AI features (estimating meals and activity, consultations, and more) have usage limits. Plus provides an expanded AI allowance beyond Free. Check the App for how much you can use and how much each use takes.

In the App Store version, you may be able to buy additional AI points. The conditions are shown on the purchase screen in the App. They are not sold in the Google Play version.

When you use AI features, the App asks for your consent before sending, and then sends the necessary input or summaries of your records to external AI services. See the Privacy Policy for details.

AI answers and estimates are guides only. We do not guarantee that they are accurate or fit for your purpose. Please check the content and values before saving.

The values shown depend on what you record, the values in Apple Health / Health Connect, and the state of your device and external services. The operator does not guarantee that the values are accurate or that you will get results such as a change in weight.

The App or Plus may be temporarily unavailable because of outages at the store or external services, network conditions, device failure, and similar causes. Keep a backup in case your records are lost.

If you suffer damage for reasons attributable to the operator, the operator is liable in accordance with applicable law.

The operator may change these Terms when the change serves the general interest of users, or when the change does not conflict with the purpose of these Terms and is reasonable in light of the need for the change, the appropriateness of the new content, and other circumstances.

Before a change takes effect, we will announce on this page that these Terms will change, the revised content, and the date the change takes effect. If we change the subscription conditions to your disadvantage, we will also notify you in the App or by other means.

For questions about these Terms or Plus, use the contact form in the App or email the address below.
