Your log is yours.

What Information We Collect

We collect the information described below to provide TrueCal, improve the service, and measure TrueCal ads when you allow tracking.

Information you provide

• Account info (name, email) through Google sign-in
• Waitlist signup info (email and selection) if you join the marketing waitlist
• Body measurements (height, weight, age, sex) if you choose to provide them
• Food logs, meal descriptions, food and nutrition-label photos, voice recordings used for logging, and estimated calorie and macro totals
• Health data you choose to sync from Apple Health or Health Connect (detailed in the Health Data section below)
• Optional tracking preferences you choose to save

Information collected automatically

• Usage data (screens and pages visited, features and buttons used, log timestamps) to understand how the app is used and improve it
• Diagnostics: crash reports and performance data, used to find and fix problems and keep the app stable
• Device data (browser type, operating system, device type)
• IP address used for general location and analytics
• When TikTok attribution is enabled on iPhone and you choose Allow in Apple's tracking prompt, TikTok may collect device and advertising identifiers, IP address, basic device and app details, and install, app-open, two-day return, registration, and App Store purchase events. Purchase events can include the product, price, currency, quantity, and transaction identifiers.
• The TikTok integration does not receive your TrueCal account ID, name, email, food logs, photos, voice recordings, nutrition data, body measurements, or Apple Health data.

Information from third parties

• Google provides basic profile info when you sign in
• An AI assistant sends the tool inputs you authorize through a connector. This does not give TrueCal access to your full conversations.

Health Data (Apple Health and Health Connect)

Health sync is optional and disabled by default. If you enable it, you grant each permission through the Apple Health (iOS) or Health Connect (Android) system permission sheet.

Data we read from Apple Health (iOS)

• Weight (body mass)
• Body composition: body fat percentage, lean body mass, body mass index, waist circumference
• Activity: step count, walking and running distance, exercise time, stand time
• Energy: active energy burned and resting (basal) energy burned
• Workouts
• Heart: heart rate, resting heart rate, heart rate variability, heart rate recovery
• Sleep analysis

Data we read from Health Connect (Android)

• Weight

Data we write

Nutrition from the meals you log: dietary energy (calories), protein, carbohydrates, total fat, fiber, sugar, and sodium — written to Apple Health on iOS or Health Connect on Android.

Why we use it

Weight readings power your weight trend and progress view. Activity, energy, workout, sleep, and heart data power TrueCal's energy-expenditure (TDEE / burn-rate) model, which adjusts your calorie targets. Synced measurements are stored with your account on our servers so we can compute these models. Nutrition is written back so your other health apps reflect what you logged.

Our commitments

• We never use Apple Health or Health Connect data for advertising, marketing, or similar services, or for use-based data mining
• We never sell it, and never disclose it to third parties for advertising, marketing, or data mining
• We use it only to provide TrueCal's health and fitness features, and never for any other purpose without your permission
• We never store Apple Health data in iCloud

Revoking access and deletion

You can revoke TrueCal's health permissions at any time: on iOS, open the Health app → Sharing → Apps → TrueCal; on Android, open Health Connect → App permissions → TrueCal. Revoking stops all future reads and writes immediately. Deleting your TrueCal account deletes the health measurements we imported, along with the rest of your data. Data already written to Apple Health or Health Connect remains on your device under Apple's or Google's controls, where you can delete it directly.

AI Processing

TrueCal uses artificial intelligence to estimate nutrition. When you log a meal, the inputs you provide — typed or spoken food descriptions, food photos, nutrition-label photos, and voice recordings — are sent to OpenAI (our large-language-model and speech-to-text inference provider) to process them on our behalf and produce calorie and macro estimates.

• AI nutrition estimates are estimates and may be inaccurate; they are not medical or laboratory measurements
• OpenAI's API terms exclude our requests from being used to train their models by default, and we have not opted in to any data-sharing or training program
• Providers may retain request data for a short period (typically up to 30 days) for abuse and safety monitoring before deleting it
• We send only the data needed to fulfill your request. If you ask TrueCal's assistant to analyze your progress, the request can include relevant account data such as your weight trend or synced health metrics; it is used solely to generate that response, never for advertising, marketing, or model training
• Food lookups may also query nutrition databases (USDA FoodData Central, Open Food Facts, FatSecret). These services receive food search terms, label text, or barcodes only — never your identity, account details, or health data

How We Use Your Information

We use information for the purposes below.

• Delivering the calorie tracking service
• Providing estimated totals and summaries based on your logs
• Tracking log history over time
• Sending account-related communications
• Analyzing aggregate usage to improve TrueCal
• Measuring whether TrueCal ads led to an iPhone install, registration, or App Store purchase, only when TikTok attribution is enabled and you allow tracking

We do not:

• Sell your personal information
• Use your food logs, health data, body measurements, photos, voice recordings, email, name, or TrueCal account ID for advertising
• Use Apple Health or Health Connect data for advertising, marketing, or data mining of any kind
• Store your Apple Health data in iCloud
• Use your data to train AI models
• Share your food logs with other users
• Access your full ChatGPT conversations through the connector

Information Sharing

We share information with the providers listed below for the purposes shown.

• Google Cloud Platform for hosting and data storage
• Google Analytics for anonymous usage statistics
• Firebase Crashlytics (Google) for crash and stability diagnostics in the mobile app
• Stripe or RevenueCat for payment processing (we do not store payment details)
• Mailjet for transactional email delivery (for example: waitlist confirmations and product updates)
• OpenAI (our large-language-model and speech-to-text provider) which processes meal descriptions, food and label photos, and voice recordings to produce nutrition estimates, as described in AI Processing above
• Nutrition databases (USDA FoodData Central, Open Food Facts, FatSecret) that receive food search terms and barcodes only
• TikTok for optional iPhone ad attribution and measurement after you allow tracking. TikTok receives the limited device, advertising, and purchase event data described above. It does not receive your TrueCal account ID, name, email, food logs, photos, voice recordings, nutrition data, body measurements, or Apple Health data through this integration. TikTok describes its processing and legal terms in its advertiser tools and terms overview.

We never share Apple Health or Health Connect data with any third party for advertising, marketing, or data-mining purposes.

We may disclose information if required by law.

Tracking Controls

TikTok attribution stays off unless it is enabled in the iPhone app and you choose Allow in Apple's tracking prompt. If you choose Ask App Not to Track, the TikTok SDK does not initialize. You can later stop TikTok attribution by turning off TrueCal under Tracking in iPhone Privacy and Security settings. TikTok's terms and privacy policy govern data it received while tracking was allowed.

Data Security

• Data is encrypted in transit (HTTPS) and at rest
• Infrastructure is hosted on Google Cloud with enterprise-grade security
• Access is restricted to essential personnel only
