Privacy Policy
Effective date and last updated: October 28, 2026
This policy explains what personal information Signal Lab collects, why, who handles it and what choices you have.
Who we are
Signal Lab (https://signal-lab-jet.vercel.app) is operated by Quantum Data Technologies Ltd. (“QDT”, “Signal Lab”, “we”, “us”), 3200-650 West Georgia Street, Vancouver, BC V6B 4P7, Canada. Signal Lab is an index of free and free-to-start financial data sources.
This policy covers the Signal Lab website, the Signal Lab weekly email and messages sent to signal-lab@qdt.ai or to any other contact address shown on the site. It does not cover QDT's enterprise platform, which has its own privacy policy at qdt.ai.
Our approach: data minimization
We collect as little personal information as we can. We do not sell, rent or trade personal information, and we do not use it to build advertising profiles. Signal Lab does not ask you to create an account.
Privacy contact
Quantum Data Technologies Ltd., 3200-650 West Georgia Street, Vancouver, BC V6B 4P7, Canada. Email: signal-lab@qdt.ai. Send access, correction, deletion, withdrawal-of-consent and complaint requests here.
What we collect and why
- Weekly email signup. Your email address, so we can send you the Signal Lab weekly email. We ask for your consent next to the signup button, and we do not ask for your name. When you sign up we also log which part of the site the signup came from (for example the browse page), without your email address.
- Messages you send us (email to signal-lab@qdt.ai or to any other contact address shown on the site, feedback, corrections, sponsorship enquiries). Your email address and what you write, so we can reply and improve the site.
- Website analytics. We use Vercel Web Analytics. It does not use cookies and does not follow you across sites. It records the page address, referrer, approximate location (country, region and city), browser, device and operating system, and counts visitors with a hash that resets every 24 hours. We use it to see which pages are useful. Our hosting provider also keeps standard server logs, which can include your IP address and browser details.
- Your browser's local storage. If you close the countdown banner, your browser remembers that for 7 days. It holds no personal information. We do not set cookies ourselves.
How we use it
To send the weekly email, answer messages, run and improve the site, keep a dated note of unsubscribe and deletion requests, and protect the site from abuse.
Who handles it for us
Vercel Inc. (website hosting and analytics); Resend (stores the email signup list); Google (Gmail, used to send the weekly email and to receive your messages); and the providers of the AI tools that run Signal Lab, which process the messages and signup list data those tools handle. We only share what each provider needs. We also disclose information where a valid, legally binding order requires it.
These providers are located in, or process information in, the United States and possibly other countries, so your information may be processed outside Canada and may be accessible to foreign courts and authorities under their laws.
Automated tools
Signal Lab is run by automated AI agents. They operate our mailbox and manage the signup list: they read the messages you send us and reply to them, they export the signup list to send each weekly email, and they write the email. We do not use automated systems to make decisions about you that have legal or similarly significant effects.
How long we keep it
Signup email address: until you unsubscribe or ask us to delete it. If you do, we remove your address from the mailing list and keep a dated note of the request. Messages: we keep them in our mailbox for as long as we need them to reply and for our records. Analytics: kept in aggregated form by Vercel under its own settings.
Your choices and rights
You can unsubscribe at any time by replying “unsubscribe” to any weekly email or by emailing signal-lab@qdt.ai. We act on it within 10 business days, and we aim to do it sooner.
You can ask to see the personal information we hold about you, ask us to correct or delete it, or withdraw your consent, subject to legal limits. We respond within 30 days.
If you are not satisfied, you can complain to the Office of the Privacy Commissioner of Canada (priv.gc.ca) or, if you live in Quebec, Alberta or British Columbia, to your provincial privacy regulator: the Commission d'accès à l'information du Québec, or the Office of the Information and Privacy Commissioner of Alberta or of British Columbia.
Security and breaches
We use reputable hosting and email providers and keep the amount of personal information we hold small. If a breach creates a real risk of significant harm to you, we will notify you and the Privacy Commissioner as the law requires.
Children
Signal Lab is for developers and traders and is not directed to children.
Other sites
Links to data providers and to social media sites go to sites we do not control. Their own privacy policies apply once you leave Signal Lab.
Changes
We will post changes to this policy here with a new date. See also our Terms & Disclaimer.
