Privacy

Who is responsible

Controller of the data: Jean-Benoit Buisson, sole trader, 47 rue Vivienne, 75002 Paris, France. Email: [email protected]

Legal basis

Your IP address and your approximate country are processed as each page loads, and the basis for that is our legitimate interest under Article 6(1)(f) GDPR: a page cannot reach you at all without an IP address, and without the country we cannot point a "Check price" button at the Amazon store that actually sells the printer or the filament you are reading about. No interest beyond those two is pursued.

Who serves these pages, and what that sends abroad

Railway Corporation (548 Market Street, PMB 68956, San Francisco, CA 94104, United States) runs the servers; Cloudflare, Inc. (101 Townsend Street, San Francisco, CA 94107, United States) does the delivery. Both are established in the United States, so 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 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 parts of this site are built per request rather than served ready-made: the affiliate redirect and the live price lookup. Each reads your approximate country — from a header the CDN supplies, or otherwise from the language your browser announces — so 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 answers a request without first being handed an IP address, and this one is the same. It is never recorded in a database, never used to assemble a profile, never given to a third party.

What changes the moment you leave for Amazon

A "Check price" button takes you off this site, and from that point Amazon's own privacy policy is the one that applies. Amazon sets a cookie so that a resulting purchase is credited to us. Who you are, which laser or spool you ordered and what you paid for it never reach us — only a count of orders, in aggregate, weeks afterwards.

Third parties

Every font is served from this site's own domain, so nothing is requested from anyone else. The live price is retrieved by the server from a price-history service instead of by your browser — which is why that service never sees you at all.

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 in every case (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 turn to the authority of their own country.
