# Data flow in meinGPT chats

## How is your chat data processed?

A transparent overview of how your chat data is processed in the meinGPT platform.

**Storage in the EU**: chat history and uploads sit in EU data centres. Where a
*prompt is processed* depends on the model you choose — see step 3.

## The data flow at a glance

### Step 1: your input

- 🔐 TLS-encrypted transfer to the meinGPT platform
- 🛡️ Temporary storage in EU data centres
- 📋 Supported formats: text, PDF, image upload (jpeg, png, webp, gif), Word, PowerPoint, Excel, CSV, text file (txt), URLs
- 📦 Other formats (ZIP and other archives, audio, video, .msg/.eml) can be uploaded - the upload succeeds without an error. Whether the assistant can read the contents depends on whether the code sandbox is enabled in your workspace: with the sandbox, the file is placed in the assistant's workspace and can be unpacked and processed with code; without it, the contents are never read. Skill packages are separate - you upload those in the assistant editor under "Skills", where ZIP archives are always unpacked automatically.

### Step 2: PII filter when US models are used (if enabled)

- 🔍 Identifying personal data with EU-hosted models
- 🔄 Anonymising that data or blocking the prompt (depending on the setting)

### Step 3: forwarding to the AI model

- 🇪🇺 Depending on the model chosen: processing in the EU or the USA
- ℹ️ The model provider and the place of processing are visible at any time in the model overview
- 🔐 Encrypted transfer of your message

### Step 4: processing & response

- 🧠 Text-to-text processing in the language model
- 🔄 Stateless processing (the prompt is not stored)
- 📝 A structured response is sent back to meinGPT
- 🗑️ Immediate deletion of the temporary data at the AI provider
- ⚙️ Further processing by meinGPT where necessary

### Step 5: storing the chat history

- 💾 Encrypted storage of the chat history
- 🔐 Only you have access to your data
- 📍 Storage location: EU data centres (Germany)

### Step 6: your control

- 👀 Access to every chat history
- 🗑️ Individual chats can be deleted at any time

## Providers used

| Service   | Provider             | Location            | Data storage             |
| --------- | -------------------- | ------------------- | ------------------------ |
| Platform  | meinGPT              | 🇪🇺 EU (Germany)     | Until you delete it      |
| AI models | depends on selection | 🇪🇺 EU or 🇺🇸 USA   | None (stateless)         |

## Data protection & security

- 🚫 No permanent storage of prompts at the model providers - 🔐 TLS-encrypted
transfers, encrypted storage of the history - 🗑️ Individual chats deletable
immediately, complete deletion including backups within 7 days

- 📋 GDPR-compliant data processing agreements with every provider
- 🔒 Provider selection by data protection level (EU only, EU hosting, worldwide)

## Deletion & your rights

**Your options**:

- 🗑️ Delete individual chats: immediately, through the interface
- 🧹 Complete deletion: from every system including backups (7 days)

**Your rights under the GDPR**:

- 📋 Information about the data stored
- ✏️ Rectification of chat content
- 🗑️ Deletion of individual chats
- 📤 Data portability (export functions)

**EU processing**: when you choose EU models, your chat data does not leave the
EU. If you choose a US model, the prompt is processed there — the PII filter
can anonymise or block personal data before that happens.
