# Security & Privacy

We take a lot of steps to secure your data. We'll explain how we store and secure your data below. <br>

**Note:** Some of the methods we use to protect your data are not included below as they would lose some of their effectiveness if we publicly disclosed them.

***

## Data Storage and Encryption

<figure><img src="/files/lw6tuipLQvrUur9wbjaL" alt=""><figcaption><p>This is an example for illustration purposes.</p></figcaption></figure>

TradeStream downloads your trading data from exchanges and we store in in our servers in order to display your trading analytics. \
\
All of your trading data is encrypted in our databases using symmetric AES256 encryption multiple times. So even if someone manages to get access to TradeStream's databases they still will not be able to read your personal data.

***

### Rotating encryption keys

The encryption keys used to encrypt your data are changed on an undisclosed schedule. This is so that even if someone figures out our encryption key, by the time they've figured it out we will already be using a new set of encryption keys to secure your data. Which would mean your data stays safe.

### API Key Security and Encryption

### Backups

We take frequent backups of your data so that in case of some catastrophic technical failure we should be able to continue services as normal with at most the past few hours of data lost.
