# What data is shared with SBT
When you send us a [device data bundle (DDB)](/software/file-formats/device-data-bundle-ddb.md), you may wonder exactly what we can see. This page explains it in plain terms.
## What is inside the data
A DDB collects system logs together with your measurement data. All of that measurement data lives in one place on your BactoBox®: the **program executions database (PEDB)**. The DDB includes a copy of it.
The PEDB holds two kinds of things:
* The **measurement results** your BactoBox® computed for each program execution. For example, the electrical measurement metrics and derived values such as *Cells/mL*.
* Whatever **metadata and labels you entered yourself**. For example, the *Label*, *Dilution*, *Sampled at*, *CFU/mL*, *Measurement group*, and notes.
So the data is your measurement results plus the text you chose to type in.
## What SBT can actually see
As the manufacturer, we can in principle access the data on your device. In practice, though, we can only interpret what your labels reveal.
The labels are free text that *you* write. If you label a measurement *E. coli*, then we can read *E. coli*. If you label it with an internal code name such as *Strain A7* or *Project Falcon*, then the label reveals nothing to us. We see the code name and nothing more.
{% hint style="info" %}
### Use code names if you prefer
If your work is sensitive, use internal code names in your labels. The raw measurement stays just as useful to you, while the label keeps your context private.
{% endhint %}
## Electrical signatures stay anonymous
For each measurement, the PEDB records an electrical signature, not a biological identity. The signature describes how particles in your sample respond to an electric field. It is not a sequence, a species name, or anything that can be traced back to a specific organism.
We cannot reverse-engineer an electrical signature into a biological identity. Without your labels, a measurement is just a set of electrical numbers.
## How SBT protects your data
We treat your data as confidential. We only look at a DDB when you share it with us to get help, and we use it to support you. We protect the data and we do not repurpose it behind your back.
{% hint style="success" %}
### Short version
A DDB contains a copy of your PEDB: your measurement results plus the labels you typed. We can read your labels, but we cannot turn an electrical signature into a biological identity. Use code names if you want extra privacy, and we keep everything you share confidential.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.
## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://help.sbtinstruments.com/software/miscellaneous/what-data-is-shared-with-sbt.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
