What the Overtone extension and dashboard handle, why, and what we never touch. Last updated 18 September 2026.
Overtone is a research tool for investment analysts. It captures an earnings call the analyst is already listening to, indexes the transcript, answers questions about it with citations, and drafts a memo. The browser extension is the capture surface; the dashboard is where the resulting research lives.
Account details. Your name, email address, workspace name, and a hashed password. We need these to give you an account and keep one customer's research separate from another's. Passwords are hashed with Argon2 and are never stored or transmitted in a readable form.
Call content you choose to capture. When you press capture, the extension reads the transcript the venue already publishes on that page and, if you use the slide capture, a still frame from the video. Both are sent to our API, indexed, and stored against your workspace.
Your own work. Notes you type, questions you ask, and the answers and memos generated in response.
Operational logs. Request metadata — timestamp, endpoint, a request id, and the IP address the request came from — kept so we can diagnose faults and investigate abuse.
The extension requests access to exactly the venues where earnings calls are streamed — YouTube, and the Q4, Notified, Chorus Call and Veracast webcast hosts — plus our own API domain. It does not request tabs or access to all sites. On any other page it is inert.
Sign-in tokens are held in chrome.storage.session, which the browser keeps in memory, never writes to disk, and discards when the browser closes. They are not readable by the page the panel is injected into.
Transcripts, notes and questions are sent to the model providers that produce answers and embeddings — currently Groq and Google (Gemini) — solely to generate the response you asked for. Data is stored in Supabase (Postgres and object storage) and served from Render and Vercel. We do not sell your data, share it with data brokers, use it for advertising, or use it to train models.
Transcripts are held per customer and are never pooled across workspaces. Your workspace holds your own working copy of calls you captured.
Your research stays until you delete it. Deleting a note also deletes any captured slide image from object storage. To delete your account and everything in it, email us and we will remove it.
