# Frequently asked questions

Source: https://caltrak.app/faq

If your question isn't here, email [support@caltrak.app](mailto:support@caltrak.app). I read every message.

## Price

**Is CalTrak free?**

Yes, completely. There's no premium tier, no trial, no subscription and no ads. The only purchase is an optional one-time tip in Settings, and it doesn't change anything in the app.

**Will CalTrak start charging later?**

There are no plans for paid features. I pay to run it, and optional tips help cover the cost.

**Does CalTrak have ads?**

No. No ads and no advertising SDKs.

## Privacy and accounts

**Do I need an account to use CalTrak?**

No. There's no sign-up or sign-in. Install it and start logging.

**Where is my data stored?**

On your phone. Your food log, goals, measurements and settings stay in the app's database on your device. Search, barcode lookups, AI and meal sharing only send what that feature needs. The privacy page has the details.

**Does CalTrak sell or share my data?**

No. CalTrak doesn't sell data or use it for advertising.

**How do I delete my data?**

Delete the app and its data goes with it. Anything already written to Apple Health or Health Connect is managed in those apps. If you want feedback or a shared meal you sent removed, email support@caltrak.app.

## Logging food

**How do I log food in CalTrak?**

Scan a barcode, search, type what you ate, take a photo of your plate, menu or label, paste a recipe link, or use a custom food or saved meal.

**Where does CalTrak's nutrition data come from?**

Barcodes come from Open Food Facts. Search uses FatSecret and USDA FoodData Central. AI lookups use OpenAI or Google Gemini to estimate nutrition from what you type or photograph.

**A barcode shows the wrong calories. What do I do?**

Some products have bad data in the public databases. Tap the entry and fix the numbers. CalTrak remembers your fix for next time.

**How accurate is AI photo logging?**

It's an estimate. Nutrition labels come out the most accurate. For plates, a clear photo plus a quick note about the portion or how it was cooked helps a lot. You see every number before you save.

**Can I log restaurant meals?**

Yes. Search includes lots of restaurant items, and you can photograph a menu or describe the dish for an AI estimate. You can also share a restaurant's nutrition PDF to CalTrak and it finds what you ate. See [restaurant nutrition PDFs](https://caltrak.app/features/restaurant-nutrition-pdf).

**Can I import a recipe?**

Yes. Paste the recipe link and CalTrak works out the nutrition per serving from the ingredients.

**Does CalTrak work offline?**

Yes, for foods you've logged before, saved meals and your history. Search, barcode and AI lookups need internet.

## Goals and progress

**How does CalTrak set my calorie goal?**

The goal wizard uses the Mifflin-St Jeor equation with your age, sex, height and weight, multiplies it by your activity level, then adds a deficit or surplus for your goal. It won't go below 1,200 calories a day for women or 1,500 for men.

**Can I set my own macro targets?**

Yes. The wizard suggests protein, carbs and fat, and you can change any of them.

**What is a streak freeze?**

You earn one every 14 days you log. If you miss a single day, it gets used automatically and your streak keeps going.

## Apple Health, Android and devices

**Does CalTrak work with Apple Health and Apple Watch?**

Yes. With your permission it reads active and resting energy and your Apple Watch workouts from Apple Health, adds extra activity to your daily budget, and writes your food, weight and body measurements back.

**Is CalTrak on Android?**

Yes. It's on Google Play with the same features, and it uses Health Connect for health data.

**Does CalTrak sync between my phone and tablet?**

Not automatically. Export a backup on one device and import it on the other. That works between iPhone and Android too.

**How do I move my data to a new phone?**

Export a backup file in CalTrak, move it to the new phone and import it there. Same format on iPhone and Android.

**Can CalTrak track water?**

Yes. Turn on Hydration Tracking in the Profile tab to set a goal in fl oz, cups or ml. Coffee and other drinks count by their water value. See [water tracking](https://caltrak.app/features/water-tracking).

**Does CalTrak have widgets?**

Yes. There are 6 home screen widgets for calories left, macros and water, plus Control Center controls and Siri shortcuts. See [widgets and shortcuts](https://caltrak.app/features/widgets-and-shortcuts).

## Help

**How do I contact CalTrak support?**

Email support@caltrak.app or send feedback from the Profile tab in the app.

**Is CalTrak medical advice?**

No. The numbers are estimates to help you track. Talk to a doctor or registered dietitian before a big diet change, especially if you're pregnant, have a medical condition or have a history of disordered eating.
