Prompt Bridge processes the following data on your local device only:
- AI conversation text — read from the DOM of supported sites (ChatGPT, Claude, Gemini, Grok, DeepSeek) when you click Capture. Never collected passively.
- API keys — for AI providers you choose to configure (OpenAI, Anthropic, Google, DeepSeek, xAI). Stored encrypted at rest.
- User preferences and settings — theme choice, default provider, selected model.
Where Data Is Stored
| Data | Storage Location | Encryption |
|---|---|---|
| Conversation threads | Browser IndexedDB (local device only) | None (your device) |
| API keys | chrome.storage.local |
AES-256-GCM, key generated locally on first install |
| Settings / preferences | chrome.storage.local |
None (not sensitive) |
No data is transmitted to the publisher’s servers. The publisher operates no server.
When Data Leaves Your Device
Data is sent to third-party AI providers only when you explicitly trigger a summarisation action. It is sent only to the provider you have configured. The endpoints contacted are:
| Provider | Endpoint |
|---|---|
| OpenAI | https://api.openai.com |
| Anthropic | https://api.anthropic.com |
| Google Gemini | https://generativelanguage.googleapis.com |
| DeepSeek | https://api.deepseek.com |
| xAI / Grok | https://api.x.ai |
Use of these APIs is governed by the respective provider’s own privacy policy and terms of service.
Data Retention
All data persists locally until you explicitly delete it:
- Delete individual threads from the Threads tab.
- Delete all data via Settings → Clear All Data.
- Uninstalling the extension removes all stored data.
What We Do NOT Do
- We do not collect telemetry, analytics, or crash reports.
- We do not send conversation content to any developer-controlled server.
- We do not share any data with third parties except the AI provider you explicitly configure and invoke.
- We do not use cookies or tracking pixels.

Limited Use of Data
Prompt Bridge adheres to the Chrome Web Store User Data Policy, including the Limited Use requirements. Specifically:
- Use of information received from Google APIs will adhere to the Chrome Web Store User Data Policy, including the Limited Use requirements.
- User data is used only to provide and improve the user-facing features of the extension (capturing AI conversation context, summarising it on request, and injecting it into another supported AI chat).
- We do not transfer user data to third parties except as required to perform the user-initiated action (e.g., sending text to a configured AI provider for summarisation), for legal reasons, or as part of a merger / acquisition / sale of assets with explicit notice to the user.
- We do not use user data to serve advertisements, including personalised, retargeted, or interest-based ads.
- We do not allow humans to read user data unless we have the user’s explicit consent for specific data, it is necessary for security purposes, to comply with applicable law, or the data has been aggregated and anonymised.
Children
This extension is not directed at children under 13 and does not knowingly collect data from children.
Changes to This Policy
Material changes will be reflected by updating the effective date above and noted in the extension’s release notes on the Chrome Web Store.
