1. Summary
The kereszteszsolt.hu website is a static personal website for professional presentation, public projects, digital products, content links, and public profile links.
The website does not require an account or login. It does not use advertising cookies, marketing pixels, ad profiling, or marketing tracking.
The website itself does not set first-party cookies. It may use localStorage to remember privacy choices and, if separately enabled, convenience preferences such as language and appearance mode.
The website may use Cloudflare or a similar infrastructure provider for hosting, DNS, CDN, security, bot protection, traffic management, and technical delivery.
Cloudflare Web Analytics / Real User Monitoring (RUM) is optional on this website and is loaded only when analytics is enabled in the privacy settings.
2. Scope
This Privacy Policy applies to the kereszteszsolt.hu website, including public pages, legal pages, project pages, product links, support pages, content pages, and public profile links.
It does not apply to third-party websites, browser stores, installed browser extensions, GitHub, YouTube, TikTok, LinkedIn, Instagram, Facebook, X, Linktree, Buy Me a Coffee, Cloudflare pages outside this website, or other external services opened from links on the website.
3. Local browser storage and choices
The website itself does not set first-party cookies. It does not use IndexedDB.
The website may use localStorage in the visitor's browser for the following purposes:
| localStorage key | Purpose |
|---|---|
kereszteszsolt.privacyConsent | Remember the privacy choice, consent version, update date, saved time, convenience-preference decision, and analytics decision |
kereszteszsolt.locale | Save the selected language when convenience preferences are enabled |
kereszteszsolt.theme | Save the selected light, dark, or system appearance mode when convenience preferences are enabled |
The localStorage entries are not used for marketing tracking, advertising, or creating a central user profile.
If the visitor chooses essential-only operation or erases all choices, optional convenience preferences are removed and the optional analytics script is not loaded.
If the URL contains a language prefix, that URL selects the language. Entry routes without a language prefix may use an allowed saved language preference or the browser language signal to redirect to a supported language.
4. Essential technologies
The website may use essential technologies for secure and stable operation and to remember privacy choices. These may include localStorage, beacons, Cloudflare security cookies, Cloudflare challenge scripts, bot-protection scripts, email-protection scripts, or other technical delivery scripts.
These technologies are part of essential operation where needed and are not used for advertising or marketing tracking.
Cloudflare security cookies and technical scripts do not necessarily appear during every visit. They may appear only if the relevant Cloudflare security, challenge, bot-protection, load-balancing, rate-limiting, email-protection, or traffic-management feature is active and needed.
Examples may include:
| Technology or feature | When may it appear? | Purpose |
|---|---|---|
Cloudflare security cookies, for example __cf_bm | If bot protection, Bot Fight Mode, Bot Management, or challenge-related protection is active and needed | Detect bot traffic, handle automated or suspicious requests, and protect the website |
Cloudflare challenge cookie, for example cf_clearance | After a Cloudflare Challenge, Managed Challenge, Under Attack Mode check, or similar security check | Remember that the visitor completed the security check |
Cloudflare load balancing or traffic management cookies, for example __cflb or _cfuvid | If the relevant Cloudflare feature is active and needed | Support stable delivery, load balancing, rate limiting, or traffic management |
| Cloudflare technical scripts | If Cloudflare runs a security check, email protection, bot protection, or technical delivery feature | Provide security, availability, email address protection, or technical delivery |
More information about Cloudflare cookies is available in the Cloudflare Cookies documentation (opens in a new tab).
5. Optional Cloudflare Web Analytics / RUM
Cloudflare Web Analytics / RUM is optional on this website. It is loaded from static.cloudflareinsights.com only after analytics is enabled in the privacy settings.
This measurement is used for aggregate traffic and performance understanding, not for marketing tracking, advertising, or creating individual visitor profiles.
The following categories and metrics may be involved in aggregate measurement:
| Category or metric | Meaning |

| Browser | Type of browser used by the visitor |

| Country | Country-level aggregate view of visits |
| Affected page element | Page part or element related to a performance metric |
| LCP | Largest Contentful Paint, a loading performance metric |
| INP | Interaction to Next Paint, a responsiveness metric |

According to Cloudflare, Cloudflare Web Analytics does not use client-side state such as cookies or localStorage to collect usage metrics and does not fingerprint individuals for analytics display.
