QuantLogix offers Chromium browser extensions, including the official AI Stock Signals toolbar extension and the QL Everywhere cashtag hover extension. These extensions may request local storage for settings and permission to contact quantlogix.ai to retrieve scores, quotes, or account-linked watchlist data you choose to connect.
QL Everywhere detects explicit $TICKER cashtags on pages you visit and sends only those ticker symbols to QuantLogix for scoring. It does not upload page HTML, form fields, passwords, or your full browsing history. You can disable Everywhere per site from the extension popup. Optional account pairing for the official toolbar extension uses a short-lived code you initiate from QuantLogix.
When you connect an AI client (for example Claude, Cursor, or Claude Code) to the QuantLogix MCP server at https://quantlogix.ai/api/mcp, QuantLogix processes an OAuth 2.1 authorization so the client can call tools on your behalf within your subscription tier. You can revoke the session. API keys (ql_…) are an alternative credential for headless use. Tool calls may include tickers and prompts you supply through the client; see also the API documentation at /api-docs and /mcp-docs.
QuantLogix's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.
Connecting a Google account is optional and never happens by default. If you connect one from your profile, QuantLogix can access your Google Calendar, Google Drive, Gmail and Google Meet data, limited to the permissions you grant on Google's consent screen, so that your QuantLogix assistant can act on your requests: summarizing your agenda and inbox, finding and reading documents, drafting email, scheduling meetings, and editing documents you ask it to edit. We only use this data to provide those features to you.
We do not sell Google user data. We do not use it for advertising, and we do not transfer it to third parties except as necessary to provide the features you requested, to comply with applicable law, or as part of a merger, acquisition or sale of assets with notice to you. No QuantLogix employee reads your Google data unless you explicitly ask us to for a specific item, or it is necessary for security purposes, such as investigating abuse, or to comply with applicable law.
We do not use Google user data to develop, improve or train generalized artificial intelligence or machine learning models. When your assistant needs to read Google content to answer you, that content is processed at the time of your request to generate your answer. Google content is kept only where a feature you use keeps it: a document you choose to import into QuantLogix, your own conversation history, or facts your assistant remembers for you, which you can review and delete from your profile. All of it is deleted when you delete your account.
Your Google access and refresh tokens are encrypted before storage. Our AI assistant cannot send email on its own; any email is sent only when you confirm a specific draft yourself. You can disconnect a Google account at any time from your profile, which revokes our access with Google and deletes the stored credentials, and you can also revoke access from your Google Account permissions page. Deleting your QuantLogix account disconnects every linked Google account the same way.
