Privacy Policy

Last updated: 13 October 2026

sgstocksbrief.com is an independent website operated by SG Stocks Brief (UEN 53525143B), a sole proprietorship of Loo Pin Mok registered in Singapore, and is not affiliated with SGX or any issuer. This policy explains what personal data we collect, why we collect it, and how it is handled, following Singapore's Personal Data Protection Act (PDPA).

What we collect

• Email address — when you sign up, so we can authenticate you with one-time sign-in codes. No passwords are stored.
• Document text — when you use the AI summariser, the extracted text of your uploaded PDF, or of the public SEC filing and selected exhibits you requested, is sent to DeepSeek to generate a summary. Uploaded PDFs are deleted immediately after text extraction; fetched SEC documents are not retained.
• Summary metadata — filename or SEC filing URL, document type, page or source-document count, timestamp, and a credit-usage counter. These are stored against your account.
• Server logs — IP address, browser type, and requested URL, retained for up to 30 days for security and abuse prevention.
• Page-usage events — our own small script records which page was viewed, the page you came from, and roughly how long the page was actively in use, under a random session ID held in your browser's session storage (cleared when you close the tab; no cookie is set). These go into the same server logs, are used only to see which pages are read, and are never linked to your account or email.

Why we collect it

• To authenticate you and let you sign in without a password.
• To generate AI summaries on your request.
• To enforce free-tier limits (1 summary per account) and prevent abuse.
• To understand which documents are most summarised — only in aggregate, never tied to your email in any externally-shared form.

Third parties we use

• An email-delivery service — used to send sign-in codes and verification emails. It sees only the recipient email address.
• DeepSeek — receives the extracted text of any PDF or public SEC filing you submit to the summariser, and generates the summary. Subject to their own privacy policy; we do not send your email address, IP, or any other identifying information alongside the text. Processing takes place outside Singapore, so submitting a document to the summariser involves a transfer of that document's text overseas. Do not submit documents you are not free to share.
• A VPS hosting provider — hosts our server and database in Singapore.
• Cloudflare Web Analytics — counts page views without cookies and without tracking individuals across sites.

We do not sell your data, and we do not share the personal data described above with any party other than those listed here. In particular, your email address, your account, your uploaded documents and your generated summaries are never given to any advertiser. How advertising works on this site is described below.

Retention

• Your email and account are kept until you ask us to delete the account.
• Generated summaries are kept until you delete them, or until your account is deleted.
• Uploaded PDFs are not stored at all — they exist only in a temporary file during text extraction and are removed before the summary returns.
• Server logs are kept up to 30 days, then rotated out.

Advertising and cookies

The site is funded by advertising. Advertising does not influence which companies, events or filings are covered here, and every advertisement or sponsored placement is labelled as such.

• No third-party advertising network currently serves ads on this site, and no advertising or tracking cookies are set. The only cookies the site sets are the essential ones: keeping you signed in, protecting forms against forgery, and carrying a one-off on-screen notice (such as “signed in”) to the next page.
• Directly sold placements are served from our own server, like any other part of the page. They set no cookies and tell the advertiser nothing about you; if a placement links to an advertiser's site, what happens after you click is governed by that site's own policy.
• Advertisers receive no personal data from us. We do not pass your email address, account details, uploaded documents or generated summaries to any advertiser, and we do not use them to target advertising.
• Before any advertising network is added, this section will be updated to name it, describe the cookies it sets and explain how to opt out, and, where the law requires it, you will be asked for consent first.

Your rights under PDPA

You may at any time:

• Request a copy of the personal data we hold about you.
• Ask us to correct or update any inaccurate information.
• Withdraw consent and request account deletion.
• Lodge a complaint with the Personal Data Protection Commission of Singapore.

Send any of the above requests to support@sgstocksbrief.com. We will respond within 30 days.

Changes to this policy

We may update this policy as the service evolves (for example, when we add paid subscriptions or new third-party providers). Material changes will be notified by email to registered users.
