Privacy Policy

Last updated: 14 August 2026

sgstocksbrief.com is an independent personal project, operated as a sole proprietorship by Loo Pin Mok 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.

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.
• Google AdSense — serves the advertisements shown on this site, and sets cookies in your browser to do so. See Advertising and cookies below.
• 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 Google or to any advertiser. The site does carry advertising, which is described in full 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

This site carries advertising supplied by Google AdSense. Advertising helps cover the cost of running the site. It does not influence which companies, events or filings are covered here, and no content on this site is paid placement.

• Google, as a third-party vendor, uses cookies to serve ads on this site. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the internet.
• Other third-party vendors may also serve advertisements here and set their own cookies. We do not control those cookies and cannot read what they store.
• Advertisers receive no personal data from us. We do not pass your email address, account details, uploaded documents or generated summaries to Google or to any advertiser, and we do not use them to target advertising.

Turning personalised advertising off

• Opt out of personalised Google advertising at Google Ads Settings.
• Opt out of many other vendors at aboutads.info, or youronlinechoices.eu in Europe.
• Block or delete cookies in your browser settings. Every part of this site that does not require a sign-in remains fully usable with advertising cookies blocked.

Further detail on how Google uses information from sites that use its services is at Google's partner-sites policy.

If you are in the European Economic Area, the United Kingdom or Switzerland, you will be asked for your consent before any personalised advertising cookie is set, and you can change or withdraw that choice at any time from the link in the consent notice.

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 loopinmok@gmail.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.
