Privacy & Data

1. Overview

TiHC (the “Extension”) is a Chrome browser extension for TiDB users. It provides an AI-powered side panel assistant with streaming responses, local chat history, code copy, and Markdown rendering to help users troubleshoot TiDB issues efficiently.

We take privacy seriously. This policy explains what data TiHC processes and how we protect it.

2. Data we process

TiHC does not collect personally identifiable information (PII).

Depending on usage, the Extension may process:

2.1 User input

Content you type into the chat (questions/messages)
Used only to generate AI responses

2.2 Local chat history

Up to the most recent 20 messages
Stored locally in your browser
Not automatically uploaded, synced, or shared

2.3 Non-personal technical information

Minimal technical data required for the Extension to run (e.g., runtime status)
No cookies, trackers, or fingerprinting

3. How we use data

Data is processed only to provide core features, including:

Generating AI Q&A responses
Streaming the response output
Rendering Markdown
Supporting one-click code copy

We do not:

Sell, rent, or trade user data
Use data for advertising or behavioral analytics
Track users across websites

4. Storage and retention

Chat history is stored only on your local device.
Up to 20 messages are kept; older entries are overwritten.
You can delete all local data by clearing browser data or uninstalling the Extension.

TiHC itself does not perform long-term server-side storage of your data.

TiHC does not proactively share user data with third parties.

To generate AI responses, user input may be sent to an AI service API for real-time processing:

Limited to the current request context
Does not include user identity information
Not used for model training or profiling by default

6. Permissions

TiHC requests only the minimum permissions required for functionality, including:

storage: to save local chat history
Side panel / active tab access: to display the assistant UI

TiHC does not:

Read browsing history
Monitor webpage content
Access account credentials

Unless you take an explicit action, the Extension does not collect page data.

7. Security

We take reasonable technical measures to protect data, including:

Keeping chat history local
Avoiding third-party tracking/analytics SDKs
Limiting permissions to the minimum necessary

8. Children’s privacy

TiHC is not intended for children under 13, and we do not knowingly collect data from children.

9. Policy changes

If this policy changes, we will publish updates via the Extension page or related documentation. Updates take effect upon publication.
