Who is responsible
Data controller: Jean-Benoit Buisson, sole trader, 47 rue Vivienne, 75002 Paris, France. Email: [email protected]
Legal basis
Each page load processes an IP address and an approximate country, on the basis of legitimate interest under Article 6(1)(f) GDPR: without the IP address no page reaches you at all, and without the country a "Check price" button cannot be pointed at the Amazon store that actually sells the kit or the bag of bases on the page. Nothing beyond those two is pursued.
Who serves these pages, and what that sends abroad
The hosting is Railway Corporation (548 Market Street, PMB 68956, San Francisco, CA 94104, United States); the delivery is Cloudflare, Inc. (101 Townsend Street, San Francisco, CA 94107, United States). Both are established in the United States, which means every page you open here involves a transfer to that country. We keep no access logs of our own and analyse none; where either provider retains logs for technical reasons, its own privacy policy is what governs them.
What we collect
Nothing that directly identifies you: no advertising cookie, no account to create, no comment field, no newsletter.
Site analytics. Only if you accept in the banner, this site uses Google Analytics 4, from Google, to count visits, page views and clicks to Amazon. Cookies (_ga, _ga_*) are then set for up to 13 months, and Google receives a technical identifier, the page viewed and information about your device; your IP address is not stored. This data is kept for 14 months and may be transferred to the United States under the Data Privacy Framework and standard contractual clauses. The legal basis is your consent (GDPR Art. 6(1)(a)). Without your consent, no Google script loads. Your choice is kept for 6 months in your browser, and you can change it at any time with the “Manage cookies” link at the foot of the page.
What the server is sent
Two things on this site are assembled for each request instead of being served as ready-made files: the affiliate redirect and the live price lookup. Each of them reads your approximate country — from a header the CDN supplies, or otherwise from the language your browser announces — so that a button opens the right Amazon store in the right currency. The country is used to build the response and stored nowhere.
No web server can answer a request without receiving an IP address, and this one is no different. That address is never written to a database, never used to assemble a profile, and never handed to anybody.
The moment you leave this site for Amazon
Pressing a "Check price" button leaves this site, and from that moment Amazon's own privacy policy governs. Amazon sets a cookie so that any resulting purchase is credited here. Your identity, which kit or bag of bases you ordered and what you paid for it are never sent to us — only an aggregate count of orders, weeks later.
Third parties
Every font is served from this site's own domain, so your browser requests nothing from anyone else — except Google Analytics, and only once you have accepted it in the banner. A live price is retrieved by the server from a price-history service rather than by your browser, and that is why the service in question never sees you.
Your rights
Your IP address is personal data, even though we record it in no database of ours. You therefore hold the rights of access, rectification, erasure, restriction and objection set out in Articles 15 to 21 of the GDPR. In practice we keep no identifier that would let us trace your requests: under Article 11 of the GDPR we are not required to collect additional information for the sole purpose of identifying you. Write to us if you believe we hold something about you, and we will look into it.
The right to lodge a complaint with a supervisory authority applies regardless (Article 77 GDPR). Since the publisher is established in France, that authority is the CNIL — Commission nationale de l’informatique et des libertés, 3 place de Fontenoy, TSA 80715, 75334 Paris Cedex 07, France. A reader resident in another member state may equally approach the authority of their own country.
