Information we collect

Luna asks for a few kinds of information so it can calculate your nutrition targets and keep track of your progress:

Profile details you enter

• Name, date of birth, and gender
• Height, current weight, and goal weight
• Activity level, dietary preferences, and allergies
• Daily water and sleep targets
• Your primary health goal (e.g. lose weight, build muscle)

Meal and activity data

• Meals you log, including any nutrition estimates generated for them
• Your daily logging streak
• Photos you choose to attach to a meal, if you grant photo library access

Account and purchase information

• Your email address, if you sign in with Apple or provide one
• Subscription status and purchase history for Luna Pro, handled by our payment provider (see below)

Technical information

• Basic device and crash diagnostics, used only to fix bugs

How we use it

We use the information above to:

• Calculate your BMI, BMR, daily calorie target, and macro breakdown
• Estimate the nutrition content of meals you log
• Show your streak and nutrition trends over time
• Recommend recipes that fit your diet and goals
• Manage your Luna Pro subscription and restore purchases
• Diagnose and fix crashes or bugs

We don't use your health information for advertising, and we don't sell it.

Where your data lives

Your profile, meal logs, and streak are stored locally on your device using standard on-device storage, not in a cloud account tied to your identity. That means:

• Uninstalling the app, or using "Clear local cache" or "Delete Account" in Settings, permanently removes this data from your device.
• Data isn't automatically synced across devices unless a future version of the app explicitly adds that and tells you.

Some information — like your subscription status and any nutrition estimates generated by our AI provider — necessarily passes through servers to be processed, described next.

Third-party services

Luna relies on a small number of outside services to work. Each only receives the information it needs to do its job:

• Apple (Sign in with Apple, App Store payments) — handles authentication and in-app purchases if you use these features. Apple's own privacy policy governs data handled on their side.
• RevenueCat — manages Luna Pro subscription status and purchase validation.
• Our nutrition-estimate provider — receives the food name you enter so it can return an estimated calorie/macro breakdown. It does not receive your profile or identity.
• Crash and error reporting — receives technical diagnostics (device type, OS version, and the error itself) to help us fix bugs. This is not linked to your name or health data.

Sharing and disclosure

We don't sell your personal information. We only share it with the service providers above, as needed to run the app, or if required by law — for example, in response to a valid legal request.

Security

We use reasonable technical and organizational measures to protect your information. No method of storage or transmission is 100% secure, so we can't guarantee absolute security, but we work to keep your data safe and minimize what leaves your device in the first place.

Children's privacy

Luna is not directed at children and is not intended for use by anyone under 16. We don't knowingly collect personal information from children. If you believe a child has provided us with personal information, contact us and we'll remove it.

Your choices

Changes to this policy

If we make material changes to this policy, we'll update the "Last updated" date above and, where appropriate, notify you in the app. Continuing to use Luna after changes take effect means you accept the updated policy.

The service

Luna lets you log meals, track nutrition, estimate calorie and macro targets, follow a logging streak, and get recipe suggestions based on your profile and goals. We may add, change, or remove features over time.

Eligibility

You must be at least 16 years old to use Luna. By using the app, you confirm that you meet this requirement.

Your account and data

Your profile and meal data are stored locally on your device, as described in the Privacy Policy above. You're responsible for the accuracy of the information you enter — Luna's calculations (BMI, BMR, calorie targets, nutrition estimates) are only as good as the data you provide, and are estimates, not exact measurements.

Deleting the app, or using "Delete Account" in Settings, removes your local data permanently. We can't recover it for you afterward.

Subscriptions and payment

Luna Pro is an optional subscription that unlocks additional features. A few things to know:

• Payment is processed by the Apple App Store or Google Play, depending on your device, and is subject to their respective terms.
• Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel your subscription from your device's App Store or Play Store account settings — we can't cancel it for you directly.
• If you reinstall the app or switch devices, use "Restore Purchase" in Settings to reconnect an existing subscription.
• Prices, trial terms, and promotional offers are set at the time of purchase and shown before you subscribe.

Health disclaimer

Acceptable use

Don't use Luna to:

• Attempt to reverse-engineer, disrupt, or gain unauthorized access to the app or its backend services

Intellectual property

Luna's design, branding, and code are owned by us or our licensors. Content you create in the app — like your own meal notes — remains yours. You grant us the limited right to store and process that content solely to provide the app's features to you.

Third-party services

Luna uses third-party services to operate, including Apple (Sign in with Apple and App Store payments), RevenueCat (subscription management), and a nutrition-estimate provider. Your use of features backed by these services is also subject to their own terms.

Disclaimer of warranties

Luna is provided "as is" and "as available," without warranties of any kind, whether express or implied, including warranties of merchantability, fitness for a particular purpose, or non-infringement. We don't guarantee the app will be uninterrupted, error-free, or that its nutrition estimates will be fully accurate.

Limitation of liability

To the fullest extent permitted by law, we are not liable for any indirect, incidental, special, or consequential damages arising from your use of Luna, including reliance on any nutrition estimate or recommendation it provides.

Termination

You can stop using Luna at any time by deleting the app or your account. We may suspend or terminate access to the app if you violate these terms.

Changes to these terms

We may update these terms from time to time. If we make material changes, we'll update the "Last updated" date above and, where appropriate, notify you in the app. Continuing to use Luna after changes take effect means you accept the updated terms.
