Calmeter LLC ("us", "we", or "our") operates the Calmeter mobile application (the "App"). This Privacy Policy explains what data we collect through the App, how we use it, who we share it with, and the rights you have over your information.
For information about data collected through the Calmeter website, please see our Website Privacy Policy at calmeter.com/privacy.
Information We Collect
Account Information
When you create an account, we collect your name and email address. If you sign in with Google or Apple, we receive your name and email address from those providers in accordance with their privacy policies.
Health and Body Metrics
To generate your personalized nutrition plan, we collect:
Age
Biological sex
Height
Weight
Activity level
Weight goal and target weight
This information is stored securely and used solely to calculate and personalize your daily nutrition targets.
Nutrition and Meal Data
As you use the App, we collect:
Meals you log, including food names, portion sizes, and nutritional values
Daily calorie and macro intake (carbohydrates, protein, fat, fibre, sugar, sodium)
Water intake
Weight entries over time
Meal Photos
When you use the camera feature to log a meal, your photo is uploaded to our secure cloud storage and processed by an AI image analysis service to identify food items and estimate nutritional content. Photos are associated with your account and retained as part of your meal history.
Device and Usage Data
We collect information about how you use the App, including features accessed, events performed, and general usage patterns. We also collect device information such as device model, operating system version, and crash reports to diagnose and fix technical issues.
Push Notification Token
If you enable push notifications, we store a device token provided by Apple to deliver notifications such as meal analysis results and personalized insights.
Advertising Identifier, Attribution & Tracking
With your permission, the App accesses your device's Advertising Identifier (IDFA) and related identifiers to measure our marketing and understand how people discover Calmeter ("attribution"). When you first use the App, iOS asks whether you allow tracking. We only access these identifiers if you allow it, and you can change this anytime under Settings → Privacy & Security → Tracking. If you don't allow tracking, the App works fully — we simply measure installs in a privacy-preserving, aggregated way (Apple's SKAdNetwork).
We use AppsFlyer, a mobile measurement and attribution provider, to process this data. AppsFlyer may receive your device identifier, an app-specific user identifier, and subscription/purchase events to attribute app installs and subscriptions to marketing campaigns. This information may be used to track you across apps and websites for our advertising and marketing purposes.
How We Use Your Information

Create and manage your account
Generate and personalize your nutrition plan
Analyze meal photos using AI to identify food and estimate macros
Deliver push notifications you have opted into
Provide personalized insights and progress tracking
Process your subscription through Apple
Diagnose crashes and technical errors to improve the App
Understand how the App is used in aggregate to guide product improvements
