Calya ("we," "us," or "our") respects your privacy. This Privacy Policy explains how we collect, use, and protect your information when you use the app. If you do not create an account, your profile, food diary, weight history and photos stay on your device, although the food you choose to analyze is sent for analysis. Other information leaves your device so that the app can analyze your food, sync your account, manage your subscription, and help us understand and improve the app and its marketing, and this policy explains what that information is and where it goes.
We collect the following information when you use Calya. You provide some of it directly. The rest is collected automatically by the app and by software from our service providers that is built into it, such as our analytics, subscription and advertising measurement tools.
If you connect Apple Health, Calya can exchange active energy, weight and nutrition information with it. These readings stay on your device, except that imported weight may sync when you have an account. We do not use Apple Health information for advertising or marketing.
We use your information to sign you in, calculate your daily calorie, protein, carb and fat goals, analyze the food you log, sync and restore your data when you have an account, manage your subscription, and answer your support requests. We also use it to understand and improve the app and its marketing, and to find and fix problems. Usage analytics does not include the names of foods or exercises, calories, macros, age, sex, goals or your account ID. We do not sell your personal information.
Calya shows no ads, but we run advertising campaigns for the app and measure their results with Meta. For this purpose, your device and advertising identifiers, usage and purchase information, advertising data about campaigns and app installs, and your IP address may be linked to you and used for our own marketing and for third-party advertising. Apple treats this use as tracking, and its App Tracking Transparency feature gives you control over it, as explained in Your Choices.
Calya uses a third-party AI service, OpenRouter, to analyze food. When you use this feature, we send OpenRouter your food and nutrition label photos, your typed food descriptions, your corrections and barcode product details. OpenRouter may pass these requests to the AI company behind the chosen model.
You decide when this happens. Each analysis begins when you take or choose a photo, scan an item or type a food, and the scan screen tells you that AI will identify the food. Nothing is sent to OpenRouter until you start an analysis, and you agree to each analysis by starting it yourself. Please keep your photos and descriptions focused on your food.
Food photos on our servers are deleted after 180 days. Copies on your device are kept after that time. We keep your account details, profile, food diary, exercise and weight history, and support messages for as long as we need them to provide the app, or until you delete your account or ask us to delete them. We keep purchase, usage and advertising measurement information for as long as we need it for the purposes described in this policy, or until you ask us to delete it. Information stored on your device stays there until you delete it, delete your account or remove the app.
We do not store the information you send to the AI features after your result is returned. It is handled by OpenRouter according to the privacy policies linked in this policy.
We use reasonable technical and organizational measures to protect your information, including encrypted connections between the app and our services. No system is completely secure, so we cannot guarantee absolute security.
You can turn off Marketing & analytics at any time in Settings, under Other. When you do, the app stops sending usage events to PostHog. Purchase information that RevenueCat handles to manage your subscription, and information that Meta receives, may continue.
Apple's App Tracking Transparency controls whether apps may use your device's advertising identifier for tracking. You can change this permission at any time in your iPhone Settings, under Privacy & Security, Tracking. When tracking is not allowed, the advertising identifier is not available to Calya, although other device identifiers and events described in this policy may still be sent to measure advertising.
You can delete your account in Settings, using Delete Account. This removes the data linked to you on our servers and clears it from your device. It does not cancel your subscription, which you manage in your Apple account settings. Information that Apple, Google or Meta already hold is handled under their own privacy policies.
You can stop sending food to OpenRouter at any time by not starting another analysis, and you can change the app's access to your camera, photo library and Apple Health in your iPhone Settings. To withdraw consent in any other way or to make any other request about your information, contact us using the email at the end of this policy.
Calya is not intended for children under 13, and we do not knowingly collect their personal information. If you believe a child has given us personal information, please contact us using the email at the end of this policy and we will remove it.
We use your information to provide the services you ask for, with your consent where we ask for it, and for our legitimate interests in improving the app and preventing abuse.
We ask for your consent before your information is sent to OpenRouter, and you can withdraw it at any time.
You may ask us for access to your information or a copy of it, and ask us to correct or delete it. You may also object to or restrict how we use it. Withdrawing your consent does not affect processing that happened before you withdrew it. To use these rights, please contact us using the email at the end of this policy. You also have the right to complain to your local data protection authority.
Our service providers may process your information in countries other than your own, which may have different data protection laws.
Depending on your state, you may have the right to know, access, correct, and delete your personal information, and to receive a copy of it. To use these rights, please contact us using the email at the end of this policy. We will not treat you differently for using them. We do not sell your personal information.
