This policy explains what personal data Engineer Booklet processes, why, on what legal basis, and what rights you have over it — including the specific rights granted under the EU General Data Protection Regulation (GDPR), the UK GDPR, the Privacy and Electronic Communications Regulations (PECR), and Switzerland's Federal Act on Data Protection (FADP).
Engineer Booklet ("we," "us," "this site") operates engineer-booklet.com and the associated YouTube channel. It's run independently, without a separate registered business entity. For the purposes of GDPR and UK GDPR, Engineer Booklet is the data controller for the processing described in this policy. Every privacy matter — questions, corrections, removal requests, or anything else in this policy — goes to a single address: info@engineer-booklet.com.
The site itself has no accounts, no forms, and no server-side database — it's a static site, and it doesn't ask you for anything. Two things happen in the background regardless:
Beyond that, the only other data processing happens through third parties you interact with directly — playing a YouTube embed, or (once live) seeing an ad — each covered in its own section below.
Under GDPR Article 6, every purpose we (or a processor on our behalf) process data for needs a lawful basis. Here is ours, purpose by purpose:
| Purpose | Data involved | Legal basis |
|---|---|---|
| Remembering your theme choice | Local storage, browser-only | Strictly necessary for the feature you asked for — no consent required (ePrivacy Art. 5(3) exemption; GDPR Art. 6(1)(b)/(f)) |
| Remembering your cookie-consent choice | A cookie set by Google's consent message | Strictly necessary to respect and record your choice — no consent required (ePrivacy Art. 5(3) exemption; GDPR Art. 6(1)(c), Art. 7(1)) |
| Keeping the site secure and running | Server access logs | Legitimate interests (GDPR Art. 6(1)(f)) — securing infrastructure against abuse |
| Showing personalized/measured ads | Advertising cookies, set by Google | Your consent (GDPR Art. 6(1)(a); ePrivacy Art. 5(3) / PECR reg. 6) — asked for before any such cookie is set |
| Playing an embedded video | YouTube cookies, set by Google once you press play | Your consent, given by the act of pressing play on third-party content after the consent message, where shown, has been answered |
If you're in the EEA, UK, or Switzerland, a consent message from Google (a Google-certified consent management platform, run through AdSense) appears on your first visit, before any advertising cookie is set. Your choice is stored in a cookie set by that message, and you can change or withdraw it at any time with the Cookie settings link at the bottom of every page — see Exercising your rights.
| Name / storage key | Set by | Purpose | Category |
|---|---|---|---|
eb-theme | Us (local storage) | Remembers light/dark mode | Strictly necessary |
Consent cookies (e.g. FCCDCF, FCNEC) | Google's consent message | Remembers your cookie-consent choice | Strictly necessary |
Advertising cookies (e.g. via doubleclick.net) | Google AdSense | Ad personalization & measurement | Advertising — requires consent |
YouTube cookies (e.g. YSC, VISITOR_INFO1_LIVE, PREF) | YouTube / Google | Video playback & preferences | Functional — set once you play an embed |
The exact cookies Google sets can change on their end without notice; this table reflects what's typical for these services. Google's own disclosures are authoritative — see the links in the sections below.
Video pages embed YouTube via youtube-nocookie.com, which limits cookies until you actually press play. Once you play a video, YouTube (Google) may set cookies and collect data under its own privacy policy. We don't receive or see any of that data ourselves.
This site uses Google AdSense to show ads. Google and its advertising partners use cookies to serve ads based on your prior visits to this and other sites. You can review or opt out of personalized advertising at Google Ads Settings, and read more at How Google uses information from sites that use its services.
Visitors in the EEA, UK, and Switzerland see Google's consent message before any ad-related cookie is set, and can change or withdraw their choice at any time with the Cookie settings link at the bottom of every page. If you decline, Google shows non-personalized or limited ads instead.
We don't sell personal data, and we don't have any of our own to share beyond what a third party collects directly through your own interaction with their embed. The processors and recipients involved are:
Google LLC is based in the United States. Where Google processes data described in this policy outside the EEA/UK/Switzerland, it does so under recognized safeguards — Google is a certified participant in the EU-U.S. Data Privacy Framework and its UK and Swiss extensions, which the European Commission, the UK, and Switzerland recognize as providing an adequate level of protection. See Google's own privacy policy for their current certification and safeguards.
We don't retain personal data ourselves — there's no database on our end to retain it in. Your theme preference stays in your browser's local storage until you clear your browser data. Your consent choice stays in the consent cookie until it expires or you clear it. Server access logs are retained by Hostinger under its own retention schedule; see Hostinger's privacy policy for specifics. Data held by Google (YouTube/AdSense) is retained under Google's own policies, which you can review or manage at Google's Data & Privacy controls.
If GDPR, UK GDPR, or the Swiss FADP applies to you, you have the following rights over your personal data. Because we hold so little of it ourselves, most requests will point you to the relevant third party (Google) — but we'll always help you figure out where to go.
Every request — removal, access, correction, objection, or anything else above — goes to the same place: email info@engineer-booklet.com and describe what you'd like. We'll respond within one month, as GDPR Article 12 requires (extendable by two further months for complex requests, in which case we'll tell you why). To change or withdraw cookie consent specifically, use the Cookie settings link at the bottom of any page on the site, which reopens the consent message, or clear your browser's site data for engineer-booklet.com. To control what Google does with data it holds, use Google's own privacy controls directly, since we can't act on Google's data on your behalf.
We'd rather you raised a concern with us directly first, at info@engineer-booklet.com, so we can try to put it right. You're also entitled to lodge a complaint with a supervisory authority:
This site is not directed at children, and we do not knowingly collect personal data from children under 16 — or the age of digital consent set by your own country's law, which under GDPR Article 8 may be as low as 13. If you believe a child has provided us data, contact us and we'll delete it.
Browser "Do Not Track" signals were never standardized around a common meaning, so this site doesn't respond to them. We do honor the Global Privacy Control (GPC) signal where your browser sends one: if detected, we ask Google to show you non-personalized ads only, meaning ads that are not based on your past browsing. Google may still use cookies for things like frequency capping, aggregated reporting and fraud prevention. In the EEA, UK and Switzerland, the consent message still asks for your choice, because the law there requires it.
If what this site collects or how it uses ads changes materially, we'll update this page and change the "last updated" date above. We won't reduce your rights under this policy retroactively without your consent.
Questions, removal requests, and any other enquiry covered by this policy all go to one address:
