Privacy

Your log is yours.

No ads. No data sales. No selling your "anonymized" food history to insurance companies.

Last updated: June 15, 2026

In one sentence: we store what you log so you can see it tomorrow. That's the whole point. Anything else would break the product.

What we collect

Your account: email, name (if you give one).
Your log: meals, weights, goal settings.
Health data you choose to sync: if you turn on Apple Health or Health Connect sync — and only then — the measurements listed in the next section.
Basic device info: phone type, app version — for crash reports.

What we don't

Location.
Contacts.
Ad identifiers.
Anything we don't need to run the app.

Apple Health & Health Connect

Health sync is optional and off until you turn it on. When you do, TrueCal connects to Apple Health on iOS or Health Connect on Android, and you approve each permission in the system sheet.

What we read on iOS, with your permission: weight, body fat percentage, lean body mass, body mass index, waist circumference, steps, walking and running distance, exercise time, stand time, active energy burned, resting (basal) energy burned, workouts, heart rate, resting heart rate, heart rate variability, heart rate recovery, and sleep.

What we read on Android: weight.

What we write back: the nutrition you log — calories, protein, carbohydrates, fat, fiber, sugar, and sodium — so the rest of your health apps see your meals too.

Why we read it: your weight history feeds your weight trend, and your activity, energy, workout, sleep, and heart data feed the burn-rate (TDEE) model that keeps your calorie target honest. Synced measurements are stored with your account on our servers so we can compute that model for you.

Our commitments on health data:

Never used for advertising or marketing, ours or anyone else's.
Never sold, and never disclosed to third parties for advertising, marketing, or data mining.
Never used for any purpose other than providing TrueCal's health and fitness features.
Never stored in iCloud.

Turning it off: revoke access anytime — on iOS in the Health app under Sharing → Apps → TrueCal, on Android in Health Connect's app permissions. Revoking stops all future reads and writes. Deleting your TrueCal account deletes the health measurements we imported along with everything else. Data already written to Apple Health or Health Connect stays on your device, under your control.

How AI is involved

TrueCal estimates nutrition with AI. When you log a meal, the food description you type, the food or label photo you attach, or the voice clip you record is sent to OpenAI — our large-language-model and speech-to-text provider, operating under our API agreement — to turn it into a nutrition estimate. Estimates are estimates, not lab measurements.

OpenAI's API terms exclude our requests from model training by default, and we have not opted in to any training program.
Providers may retain inputs briefly (typically up to 30 days) for abuse and safety monitoring, then delete them.
We send what's needed to answer the request and nothing else. If you ask TrueCal's assistant to analyze your progress, that request can include relevant log data — like your weight trend or synced health metrics — used to produce that answer only, never for advertising or model training.
Food lookups also query nutrition databases (USDA, Open Food Facts, FatSecret). They receive the food terms or barcode — never your identity or health data.

How we use it

To run the app. Your food log calculates nutrition, your weight and health data feed the trend and burn-rate model, your email lets you sign in. That's the whole list.

Who sees it

You. Our infrastructure provider (Google Cloud — under standard data-processing agreements) handles storage and traffic, and OpenAI (the AI provider described above) processes meal inputs to produce estimates. No advertiser. No data broker. No insurer. Period.

Your controls

Export: Pro includes CSV food-log export. You can also email privacy@truecal.com to request a copy of your data.
Delete: Settings → Delete account. Your account is deactivated right away, personal identifiers are removed, and retained records are scheduled for deletion.
Edit: Tap any meal, fix or remove it.

Security

Encrypted in transit (TLS 1.3) and at rest. Standard hashing on credentials. We follow OWASP guidance and treat your food log like it's our own — because it is.

Children

TrueCal is for ages 13 and up. It's not directed at children under 13 and we don't knowingly collect their data — if we learn we have, we delete it. If you're 13 to 17, use TrueCal with a parent or guardian's consent.

Changes

If anything material changes, we'll email you and post the diff. No quiet rewrites.

Privacy

TrueCal Privacy Policy

TrueCal ("we", "us", "our") is committed to protecting your privacy. This policy explains what we collect, how we use it, and the choices you have.

Effective Date: June 15, 2026

What Information We Collect

We collect the information needed to provide the TrueCal service and improve your experience.

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

Information from third parties

Google provides basic profile info when you sign in
ChatGPT sends meal log data you create through the integration (we do not receive 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
