Privacy Policy

Last updated: August 2026

Introduction

KetoLuna ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you use our mobile application and website.

Information We Collect

We collect information you provide directly, including your name and email when you create an account, and the food, weight, glucose, and activity data you choose to log. Photos you upload are processed to identify food items and estimate nutritional content.

How We Use Your Information

We use your information to provide and improve our services, including analyzing food photos with AI to estimate macros, storing your meal history, and sending you updates about the app (if you've opted in).

Apple Health (HealthKit)

On iPhone, KetoLuna can connect to Apple Health. The connection is off until you turn it on, and you choose which categories are shared.

What we write to Health. Only what you already logged in KetoLuna: the nutrition of your meals (energy, carbohydrates, fiber, fat, protein, sugar, sodium, potassium and magnesium), the calories of activities you recorded, your weight, and your blood glucose readings. You can turn any of these off, and disconnecting deletes from Health everything KetoLuna wrote.

What we read from Health. Only the active energy of the current day, measured by your Apple Watch or other apps, and only if you enable it. It is used to show your exercise and, if you ask for it, to raise that day's calorie goal.

Where it stays. Data read from Apple Health is used on your device and is never transmitted to our servers, and never stored by us. We do not use HealthKit data for advertising or marketing, we do not sell it, and we do not share it with third parties or data brokers. Your sharing preferences for this integration are stored on the device itself, not on your account.

You can review or revoke these permissions at any time in the Health app, under Sharing → Apps → KetoLuna, or disconnect the integration from KetoLuna's settings.

Telegram

If you link your account to our Telegram bot, the messages and photos you send to it are processed exactly like entries made in the app, and are subject to this policy. Telegram's own handling of your messages is governed by Telegram's privacy policy. You can unlink your account at any time from KetoLuna's settings, which stops the bot from accessing your account.

Data Retention

We retain your personal information for as long as your account is active or as needed to provide you our services. Meal history and nutritional data are kept while your account exists so you can access your tracking history. If you stop using the app, we will retain your data for up to 12 months after your last activity, after which it will be automatically deleted. You can delete your account at any time from Settings or by emailing us.

Data Deletion

You have the right to request deletion of your personal data at any time. To delete your data, you can:

• Use the "Delete Account" option in the app settings to permanently remove your account and all associated data.
• Send a deletion request to hello@ketoluna.com and we will process your request within 30 days.

Once your data is deleted, it cannot be recovered. We may retain certain information as required by law or for legitimate business purposes, such as fraud prevention.

Data Security

We implement appropriate security measures to protect your personal information. Your data is encrypted in transit and at rest.
