Hello! At Calistant, we believe that understanding your meals shouldn't feel like solving a math problem. We're here to help you build healthier habits by making meal tracking easy, smart, and even a little fun. We are not a medical or dietary service. Since this is a personal journey, we do collect some information to make your experience as helpful and personalized as possible.

This Privacy Policy ("Policy") outlines how Calistant handles your personal information during your use of the app. It explains what kind of data is collected, how it's used, and how your privacy is safeguarded. You'll also find information about your rights and the choices you have regarding your data. This Policy is closely linked to our Terms of Use, where additional details and definitions are available if you're curious to explore further.

Calistant is designed for individuals who are 18 years of age or older. If you are under 18, please do not create an account or use Calistant. Our systems are designed to restrict access for individuals below this age. If we discover that a user under the age of 18 has submitted personal information, we will promptly delete the data and close the account to protect their privacy.

Personal Information We Collect

We may collect your personal information through three primary sources: directly from you, automatically as you interact with our Services, and from authorized third parties.

Personal Information We Collect Directly from You

Account and Profile Information

When you sign up for Calistant, you may provide details such as your name, email address, general location (such as country), profile image (if you choose to upload one), username, password, date of birth, and gender.

• Eating and nutrition habits

• Foods, beverages, and medications you consume (including those logged via voice input, text, or barcode scanning), and in the future, possibly groceries purchased via third-party integrations

• Calorie intake and nutrient breakdown

• Dietary preferences or restrictions

• Fitness activity, exercise routines, and related goals (e.g., "increase daily protein intake")

• Lifestyle habits such as sleep data

• Body-related metrics like height, weight, and BMI

Some of this data may be considered sensitive personal information if it directly or indirectly indicates a medical or health condition.

Communications with Calistant

When you contact our team—for example, through customer support channels, feedback forms, or in-app messaging—we may collect your name, email address, and the content of those messages, including any responses you receive from us or from automated support features such as our chatbot.

Payment Information

If you purchase a Pro Subscription or any paid feature via Calistant's platform, your payment details (such as credit card number, billing address) may be processed by a third-party payment processor. Calistant itself does not store or access your full payment credentials but may retain transaction-related metadata (e.g., subscription tier, status, renewal dates) for account management and billing purposes.

Automatically Collected Personal Information: Usage, Device Data & Cookies

Calistant may automatically collect certain information related to your device and how you interact with the Services. This includes technical details such as your browser type, operating system, device model, unique identifiers (e.g., IP address, mobile advertising ID, cookie ID), internet service provider, and mobile network operator. We may also collect general location data inferred from your IP address, as well as data on your in-app behavior—such as actions taken, time spent using different features, frequency of use, navigation paths, and clicks on specific links or elements within the app or website.

What Are Cookies?

Cookies are small data files stored on your device by your browser when you visit a website or use a web-based app. Like many digital platforms, Calistant and its authorized third-party partners may use various tracking technologies—including cookies, pixels, web beacons, SDKs, log files, and local storage mechanisms—to collect information for operational and analytical purposes.

Managing Your Cookie Preferences

Your ability to manage cookies may vary depending on your location and applicable regulations. Most browsers allow you to modify your settings to accept all cookies, reject all cookies, or notify you each time a cookie is being placed on your device. Note that if you disable or reject cookies, certain features of Calistant's Services may no longer function as intended.

Personal Information We Receive From Third Parties

Calistant may receive personal data about you from various external sources, including third-party health integrations, service providers, research collaborators, marketing and advertising partners, and social media platforms. This information is used to enhance the Services and offer a more personalized and secure experience.

Service Providers

Authorized service providers may share information with Calistant as part of their role in supporting the functionality of the Services. For example, usage behavior and interaction patterns may be provided by analytics services to improve user experience, identify performance issues, or ensure system security.

Connected Health Devices

If Calistant is integrated with compatible connected devices—such as activity trackers, smart scales, heart rate monitors, glucose monitors, or other wearables—it may receive activity and biometric data with your explicit permission. This may include steps, heart rate, sleep data, weight, and workout sessions.

How We Use Your Personal Information

Calistant may use the personal information we collect for the purposes outlined below, or as otherwise clearly communicated at the time the data is collected. Please note that any activity-based data (such as logged meals, calories, or fitness routines) is used solely for delivering the core functionality of the Calistant platform and is never sold or disclosed to third parties outside of these service-related purposes.

Research and Product Development

We may use collected information in support of product improvement, usability research, and service development. As part of this process, user data may be transformed into aggregated or anonymized forms—ensuring that no individual can be identified.

• Meet legal obligations or respond to valid governmental or regulatory requests

• Protect the rights, safety, and property of users, Calistant personnel, or the general public

How We Share Personal Information

Calistant may share personal data with specific categories of third parties, always in alignment with the purposes described in this Privacy Policy and applicable legal requirements.

Service Providers and Vendors

We rely on trusted third-party vendors to support day-to-day operations and to help deliver Calistant's functionality. These service providers may include providers of hosting and cloud infrastructure, payment processors, customer service platforms, data analytics providers, and IT consultants. These entities only access your data for purposes directly tied to their services and are contractually bound to protect your information.

Legal and Regulatory Requirements

Calistant may disclose personal information where required to comply with applicable laws, court orders, or legitimate requests from governmental and law enforcement authorities. This may also include disclosures for tax, audit, compliance, or public safety reasons.

Business Transitions

In the event of a potential merger, acquisition, financing, asset transfer, reorganization, or bankruptcy, personal data may be disclosed or transferred as part of due diligence or completion of the transaction.

How Calistant Retains Your Information

Calistant retains your personal information for as long as it is needed to support the purposes described in this Privacy Policy, including to comply with legal, regulatory, or reporting obligations. In some cases, applicable laws may require us to store certain data for a longer period, or allow us to retain it for archiving or business continuity purposes.

When determining how long to retain specific types of personal data, we consider several factors, including: the volume and sensitivity of the information, the potential risks associated with unauthorized access or disclosure, the reason the information was collected, whether the intended purpose can still be met, and any legal obligations or industry standards that apply.

How Calistant Protects Your Information

Calistant implements a combination of technical, organizational, and administrative measures to help safeguard your personal information from loss, misuse, unauthorized access, disclosure, alteration, or destruction. These safeguards are designed in accordance with industry best practices and are regularly reviewed to ensure ongoing data protection.

However, it is important to note that no system or method of electronic data storage or transmission over the internet can be guaranteed to be fully secure. While Calistant takes reasonable steps to protect your information, absolute security cannot be assured.

Depending on your place of residence, you may have specific legal rights regarding how your personal information is collected, used, stored, and shared. Calistant respects these rights and is committed to supporting individuals in exercising them in accordance with applicable laws.

Right to Access and Data Portability

You may have the right to request confirmation about whether Calistant processes your personal information and to access or receive a copy of your data in a commonly used, portable format, when technically feasible.

Right to Deletion

You may request that we delete your personal data, subject to certain limitations permitted or required by law (such as compliance with legal obligations or security purposes).

Right to Correction

If any personal information we hold is inaccurate or incomplete, you have the right to request that it be corrected, taking into account the nature of the data and the purposes for which it is processed.
