Privacy Policy

You sign in with Google. Google shares your name, email address and profile photo with us; we never see your Google password. We use them to identify you and show who you are in the dashboard.

When you connect Notion, MarketGain reads only the pages and databases you share with its connection and never writes back to Notion. It stores a copy of their text, split into passages with a search index of each, so the chatbot can find and cite them. Disconnecting Notion stops the chatbot at once and deletes the copies after 30 days; deleting a knowledge base or a workspace deletes them straight away.

• Questions asked to the chatbot, the answers given and the pages they cite, and “was this helpful?” votes.
• A random visitor identifier and the open conversation, kept in the visitor's browser storage only when the site's privacy setting allows it; otherwise the conversation lives only until the page is closed.
• The website address the chatbot is installed on, so you can see that the installation works. MarketGain does not track page views or browsing.
• Chatbot conversations are deleted after 400 days of inactivity.

• There are no MarketGain passwords: the only way into the dashboard is your Google sign-in.
• Your content is stored in a managed Postgres database where row-level security scopes every row to its workspace, and the browser never talks to the database directly.
• The Notion connection is read-only and scoped to the pages you chose; MarketGain cannot edit anything in Notion.
• Everything is served over HTTPS with HSTS, and the public chat endpoints are rate-limited against abuse.

• Supabase: database and sign-in.
• Cloudflare: hosting, content delivery, abuse protection, and Workers AI, which builds the search index of your pages and of each question.
• DeepSeek: generates chatbot answers. Questions, recent conversation turns and the relevant passages of your pages are sent to it to produce an answer.
• Google: sign-in. Notion: reading the pages you share.

Workspace owners can delete a workspace in Settings → General, which permanently removes its knowledge bases, synced pages, chat history and Notion connection. You can delete your account from the account menu once you no longer own a workspace.
