Privacy & disclosures

Last updated: 7 August 2026

What this site is

Protocol Index is an independent, personal hobby project. It is a convenience index: it lists the supplements from a publicly documented longevity protocol (Bryan Johnson’s Blueprint protocol) and maps each one to a matching product listing or targeted search on Amazon’s European and US marketplaces and, in Poland, Allegro.pl, with doses, timing and short evidence notes.

What this site is not

Not affiliated. This site has no affiliation, sponsorship, partnership or endorsement relationship with Bryan Johnson, Blueprint, Amazon or Allegro (beyond the standard affiliate relationships described below), or any supplement brand or manufacturer linked from these pages.
Not a lab or a vendor. Nothing listed here has been laboratory-tested, vetted or independently verified by this site, and nothing is sold by this site. All purchases happen on Amazon or Allegro, from third-party sellers, under that marketplace’s terms.
Not medical advice. Nothing on this site is medical advice. Always confirm brand, dose, ingredients, allergens, expiry and safety with the vendor and a qualified healthcare professional before buying or consuming anything.

Affiliate disclosure

As an Amazon Associate, this site earns from qualifying purchases. Outbound Amazon links carry an affiliate identifier (the tag= parameter) for the Amazon Associates programs of Amazon.com, .co.uk, .de, .fr, .es, .it and .pl. Some outbound Allegro.pl links use an affiliate redirect as well. These identifiers do not change the price you pay. Affiliate revenue is the site’s only monetization; product selection is never paid placement.

Data this site collects

There are no accounts, sign-up forms, newsletter or comments. The site uses limited traffic and outbound-click analytics to understand which pages and marketplace links are useful.

Local preferences. Your chosen country, language, theme and “owned” checklist are stored in your browser’s localStorage only. They never leave your device and are deleted when you clear your browser data.
Hosting (Cloudflare). The site is served by Cloudflare, which processes technical data such as IP addresses in server logs to deliver and secure the site. See the Cloudflare privacy policy.
Analytics (Cloudflare Zaraz and Google Analytics). Cloudflare Zaraz loads Google Analytics and sends page-view information. When an Amazon or Allegro affiliate link is clicked, it also sends an affiliate_click event with the product, selected country, marketplace channel, link type, page type/path and destination hostname. The event does not intentionally contain a name, email address, order details or the full destination URL. Cloudflare and Google may process technical identifiers and set or read cookies according to the consent choices and their own policies. See Google’s privacy policy.
Fonts and images. Web fonts are loaded from Google Fonts and product thumbnails from Amazon’s image CDN; your browser sends those servers your IP address when fetching these files, as with any embedded third-party resource. See the Google privacy policy and the Amazon privacy notice.

When you click a marketplace link

The site records the limited outbound-click event described above. Once you follow a product link, you are on Amazon or Allegro. The marketplace may set cookies or use similar technology to attribute the visit and processes your data under its own privacy notice. This site receives only aggregate affiliate reports such as clicks, ordered items and commission — never your name, address or order details. See Amazon’s privacy notice linked above and Allegro’s privacy policy.

Your rights

Under the GDPR you have rights of access, rectification, erasure, restriction, portability and objection. Because this site itself stores no personal data about you, there is usually nothing to access or erase here — for data processed by Cloudflare, Google, Amazon or Allegro, please use the contact points in their policies linked above. For any question about this site, contact: contact@protocolindex.eu.

Changes

If the site ever starts collecting data it currently doesn’t (for example, adding an analytics tool or a newsletter), this page will be updated first and the “last updated” date changed.
