Privacy notice

Last updated: 15 October 2026

This notice explains what per­sonal data this web­site pro­cesses, why, and what rights you have.

Who is responsible

This web­site is oper­ated by Derived Logic, an Amer­ican com­pany. For any ques­tion about pri­vacy, please write to contact@derivedlogic.ai.

When you visit

To deliver the pages and pro­tect the site against abuse, our host­ing pro­vider (Microsoft Azure) and our net­work and secur­ity pro­vider (Cloud­flare) pro­cess tech­nical data such as your IP address, the date and time of the request, the page reques­ted and your browser type. We do not use these data to identify you and do not com­bine them with other sources. The legal basis is our legit­im­ate interest in oper­at­ing a secure web­site (Art­icle 6(1)(f) GDPR).

Choosing your language

When you first arrive, your browser reads its own lan­guage set­ting and time zone in order to show the most suit­able ver­sion of this site. Where avail­able, it also asks our net­work pro­vider for the approx­im­ate coun­try asso­ci­ated with your con­nec­tion. This hap­pens in your browser; we do not record the result.

Cookies and local storage

This web­site sets no cook­ies. It keeps three small set­tings in your browser’s local stor­age, solely so that the site works as you have asked: your lan­guage (dl-lang), your colour scheme (dl-theme) and your pri­vacy choice (dl-con­sent). These are strictly neces­sary and there­fore exempt from con­sent under Art­icle 5(3) of the ePri­vacy Dir­ect­ive, § 25(2) of the German TDDDG and the UK’s PECR. The site con­tains no advert­ising, no track­ing and no third-party embeds; its fonts are served from our own domain.

Optional audience measurement

We use audi­ence meas­ure­ment only with your con­sent. Should we intro­duce it, it will be pri­vacy-respect­ing and aggreg­ate, and this notice will name the pro­vider before it is enabled. You may give or with­draw con­sent at any time through ‘Pri­vacy set­tings’ at the foot of every page; with­drawal does not affect pro­cessing that took place before it.

If you write to us

If you con­tact us by email, we use your address and mes­sage to reply and to con­duct any res­ult­ing cor­res­pond­ence, and we keep them only as long as that requires (Art­icle 6(1)(b) and (f) GDPR).

International transfers

Our ser­vice pro­viders are based in the United States. Trans­fers of per­sonal data from the European Eco­nomic Area, the United King­dom and Switzer­land rely on the EU–US Data Pri­vacy Frame­work and its UK and Swiss exten­sions, or on stand­ard con­trac­tual clauses, as applic­able.

Your rights

You have the right of access, rec­ti­fic­a­tion, eras­ure, restric­tion of pro­cessing, data port­ab­il­ity and objec­tion, and the right to with­draw con­sent at any time. To exer­cise any of these rights, please write to the address above; we shall reply without undue delay and within any dead­line your law sets.

Visitors in Europe

We treat the European stand­ard as the baseline for every vis­itor. In the European Union and the wider European Eco­nomic Area (Ice­land, Liecht­en­stein and Norway), this site com­plies with the Gen­eral Data Pro­tec­tion Reg­u­la­tion and with the national rules imple­ment­ing the ePri­vacy Dir­ect­ive. In the United King­dom it com­plies with the UK GDPR, the Data Pro­tec­tion Act 2018 and PECR; in Switzer­land, with the revised Fed­eral Act on Data Pro­tec­tion; and in Guern­sey, Jersey and the Isle of Man, with their own data-pro­tec­tion laws. Vis­it­ors in Albania, Andorra, Armenia, Azerbaijan, Bosnia and Herzegov­ina, Geor­gia, Kosovo, Mol­dova, Monaco, Montenegro, North Mace­do­nia, San Marino, Serbia, Türkiye and Ukraine enjoy the rights given by their national laws, many of which follow the GDPR or the Coun­cil of Europe’s Con­ven­tion 108+. Wherever your national law grants more pro­tec­tion than this notice describes, your national law pre­vails. You may com­plain to the data-pro­tec­tion author­ity of the coun­try in which you live or work; in the United King­dom, this is the Inform­a­tion Com­mis­sioner’s Office.

Visitors beyond Europe

We hold ourselves to the same stand­ard every­where. We also recog­nise the strong pri­vacy laws of part­ners beyond Europe, includ­ing Aus­tralia’s Pri­vacy Act 1988 and the Aus­tralian Pri­vacy Prin­ciples, New Zea­l­and’s Pri­vacy Act 2020, Japan’s Act on the Pro­tec­tion of Per­sonal Inform­a­tion, the Repub­lic of Korea’s Per­sonal Inform­a­tion Pro­tec­tion Act, Taiwan’s Per­sonal Data Pro­tec­tion Act, Singa­pore’s Per­sonal Data Pro­tec­tion Act and Uruguay’s Law No. 18.331; vis­it­ors there may exer­cise the rights those laws provide. In the United States, we do not sell or share per­sonal inform­a­tion, and we honour Global Pri­vacy Con­trol sig­nals by default, because noth­ing on this site tracks you.

Changes

We shall revise this notice if our prac­tices change. The date above iden­ti­fies the cur­rent ver­sion.
