# Questions

> Short answers to common questions about the Splot app.

## Does Splot estimate calories from a photo?

No. Splot has no AI of its own. Send a photo to a connected assistant such as ChatGPT or Claude: the assistant estimates the meal and saves it to your journal, marked as an estimate.

## Which phones does Splot work on?

iPhone and Android. Your journal is kept in your account, so it is the same on every device and in every connected assistant.

## Is there a web or computer version?

The journal is in the iPhone and Android apps. On a computer, use a connected assistant on its website, or the [Splot API](https://splot.health/docs/api).

## Does Splot work offline?

Splot needs an internet connection to save. Without one it says **No internet connection**, and **Retry** saves the change once you're back online.

## Which units does Splot use?

Metric, US or UK, chosen in **You → Units**, or **Automatic** to follow your phone. Targets are always in kilocalories and grams.

## Can I set targets for just one day?

Yes. In **Daily targets**, set the range to **Only this day**, or **Until a date…** for a stretch of days.

## Do planned meals count towards my totals?

No, only meals you ate. Mark a plan as eaten when you have it.

## Does Splot save my diet, allergies or preferences?

No. Splot keeps meals, your foods and recipes, your targets and your body details. Tell your assistant about your diet and allergies in the conversation.

## Where does the food data come from?

Common foods come from national food composition tables, packaged products from the Splot database and Open Food Facts, and your own foods from you.

## Can I export my journal?

Yes, whenever you like. Your journal is yours: create a read-only key in **You → Account → API Keys**, and the [Splot API](https://splot.health/docs/api) gives you every meal, food and recipe you saved, as JSON. A connected assistant can read your journal too.

## How do I delete my account?

Open **You**, tap your email, then **Delete account**. See [Delete your account](https://splot.health/docs/app/delete-account).

## How do I contact support?

Open **You** and tap **Contact support**, or email support@splot.health.
