The AI Chat Navigator browser extension adds a configurable mini-map scrollbar, prompt autocomplete and other productivity tools to ChatGPT, DeepSeek, Google AI Studio and similar chat pages. It can optionally connect to the developers’ hosted service to fetch community trends and recommendations. This policy describes the data the extension may handle, how it is stored, why it is used and the choices you have.
The extension saves a small amount of information in your browser’s chrome.storage.sync. This storage is synced by Google between your signed-in Chrome profiles and is encrypted in transit and at rest.
| Data | Where | Purpose | Sent off-device? |
|---|---|---|---|
| UI preferences (scrollbar colour, size, opacity, location, auto-hide toggle, button size/opacity, etc.) | chrome.storage.sync | Restore your preferred look and feel across your own machines | No |
| Prompt settings (whether the mini-map and prompt tools are enabled, whether to send prompts to the server, whether to show/improve prompts automatically) | chrome.storage.sync | Persist your feature configuration between sessions | No |
| Custom autocomplete prompts you save | chrome.storage.sync | Make your personal snippets available in the autocomplete dropdown across your devices | No |
| User token (random string issued by our API) | chrome.storage.sync | Authenticate anonymous requests to the AI Chat Navigator backend (e.g., to check “pro” status, fetch trending prompts or submit feedback) | No – the token itself is stored locally and only its value is sent as an HTTP header when contacting our API |
| Last used prompts cache (optional) | chrome.storage.sync | Improve prompt recommendations and avoid repeating suggestions | No |
We do not access, collect or store full chat histories, page titles, browsing history, cookies or any other personal identifiers on your device.
The extension only communicates with our servers when you enable specific features in the settings. All communication uses HTTPS. Data transmitted is minimal and pseudonymous.
When you toggle “Send prompts to server” in the settings, the extension may send parts of your prompt text to our backend to request recommendations or contribute to community-generated suggestions(https://aichatnavigator.online/prompts_feed):
/api/recommend on our server to receive rewritten suggestions and trending autocomplete options. The prompt text is not linked to your identity; it is used only to generate and return improved versions./api/community_prompts?q= with a search term. These requests include only the text you type and the pseudonymous user token to prevent abuse. Full chat contents are never sent./api/prompts, /api/task_prompts and /api/task_results. The server returns popular prompts in aggregate form; no user identifiers are attached.If you vote on a community prompt, the extension sends a POST to /api/vote containing the prompt’s ID and the vote direction (“up” or “down”). The vote is associated with your user token to prevent duplicate votes; we do not collect any personal details.
When you use the feedback form in the popup, your feedback text and user token are POSTed to /api/extension/feedback. We use this information to improve the extension. Your feedback is not published, sold or combined with other data.
On first use of server features, the extension requests a pseudonymous user token from /api/generate-token and stores it in chrome.storage.sync. This token allows the API to manage rate limits, check subscription status or return aggregated data. It is not tied to your Google account or any personal identifier. You may delete the token by resetting the extension’s settings (see Section 6).
We never sell or transfer user data to advertisers or third parties, use it for unrelated purposes, or use it to determine creditworthiness or for lending decisions. The Chrome Web Store listing also reflects these commitments.
chrome.storage.sync for syncing settings. Google encrypts this data in transit and at rest. Apart from Google and our own servers, no other service processes your data.We use industry-standard HTTPS to transmit data to and from our servers. The data stored in chrome.storage.sync is encrypted by Google. The user token is a random string, not tied to your identity. While we take reasonable steps to protect your data, no system can guarantee absolute security.
We may update this policy when features change or to comply with new legal requirements. The latest version is included in the extension package and posted on our GitHub project page. Significant changes will be highlighted in the changelog. Continued use of the extension after an update constitutes acceptance of the revised policy.
