Sage Prism — Privacy Policy
Last updated: 10 November 2026
Sage Prism publishes research on public company filings with the U.S. Securities and Exchange Commission (SEC): written posts on Substack and short videos on YouTube, TikTok and Instagram. This policy explains what information Sage Prism handles and why.
Who we are
Sage Prism is operated by an individual publisher. Contact: team.sageprism@gmail.com.
What we publish, and from where
Everything we publish is built from public SEC filings (10-K and 10-Q reports) and public market data. We do not collect, buy or use personal information to make our content.
Readers and viewers
- Substack. If you subscribe to the newsletter, Substack collects and processes your email address and any payment details under its own privacy policy (https://substack.com/privacy). We see what Substack shows publication owners: your email address, subscription status and aggregate reading statistics. We use them only to send the newsletter and understand which posts are useful. We never sell or share them.
- YouTube, TikTok and Instagram. When you watch, like or comment on our videos, those platforms process your data under their own policies. We see only the aggregate statistics and public comments each platform shows a channel owner.
Our use of platform APIs
Sage Prism uses each platform's official API only to upload videos to Sage Prism's own accounts and to read those accounts' own information. It does not access anyone else's account.
- YouTube. Sage Prism uses YouTube API Services. By watching our
videos you are also subject to the YouTube Terms of Service
(https://www.youtube.com/t/terms) and the Google Privacy Policy
(https://policies.google.com/privacy). We request permission to upload
videos and to read our channel's basic information
(
youtube.upload,youtube.readonly). - TikTok (Content Posting API) and Instagram (Instagram Graph API): used in the same way, to publish to Sage Prism's own accounts only.
The access tokens these APIs issue are stored on servers we control, are used only by our publishing software, and are never shared. We keep them until we revoke them or stop publishing to that platform.
You can see and revoke any third-party access to a Google account at https://myaccount.google.com/permissions; TikTok and Instagram offer the same in their account security settings.
Cookies
Our own software sets no cookies on your devices. Substack, YouTube, TikTok and Instagram may, under their own policies.
Not financial advice
Sage Prism describes what changed in public filings. It is not investment advice and is not a recommendation to buy or sell any security.
