This notice explains how Supplement Signal collects, uses, and shares personal information when you visit the site, read reviews, click affiliate links, or subscribe to the newsletter.
Supplement Signal is operated by Nuno Formiga. For privacy questions, contact privacy@supplementsignal.com.
Most of the personal information we process comes directly from you, for example when you submit the signup form. Some technical information is collected automatically by the website, hosting infrastructure, DNS/CDN providers, and other service providers used to run the site.
If UK or EEA data protection law applies to you, we generally rely on the following lawful bases:
Supplement Signal may include affiliate links. If you click an affiliate link and make a purchase, we may earn a commission at no extra cost to you. This does not change the price you pay. Rankings and recommendations are intended to be editorially independent, and no brand pays for placement in the rankings.
Affiliate disclosures should also appear on the relevant review or article pages themselves, not only in this notice.
The site may use cookies or similar technologies for basic functionality, security, traffic measurement, and marketing or advertising features if those tools are enabled. If you use non-essential cookies or tracking technologies, you should provide any consent or notice required by applicable law and update this policy accordingly.
We do not sell your personal information. We may share information with service providers that help us run the site and newsletter, including:
Some service providers may process personal information outside your country. If UK or EEA data protection law applies and personal information is transferred internationally, we aim to rely on an appropriate transfer mechanism where required, such as adequacy regulations or standard contractual clauses.
We keep subscriber information for as long as needed to operate the newsletter, maintain unsubscribe and suppression records, resolve disputes, prevent abuse, and comply with legal obligations. Technical logs are generally kept only as long as reasonably necessary for security, operational, and diagnostic purposes.
Depending on where you live, you may have rights to request access to your personal information, ask for correction or deletion, object to certain processing, request restriction, withdraw consent, or ask for a copy of the information you provided to us. The easiest way to stop newsletter emails is to use the unsubscribe link in any message.
If you have concerns about how your information is handled, please contact us first at privacy@supplementsignal.com. If UK or EEA law applies to you, you may also have the right to complain to your local data protection authority.
We may update this privacy notice from time to time. When we do, we will update the “Last updated” date above and, where appropriate, take additional steps to notify subscribers of material changes.
