Your choice comes first
Optional external media and Google sign-in are off until you allow them. Accept all optional features, reject them, or choose categories in . Rejecting optional features does not prevent you from browsing or sending an inquiry. No advertising category is offered because none is configured on this website, and no third-party analytics service is used either. This website does keep a simple internal count of how many times each article is read, so we know what to write about next; it does not use a cookie of its own (it reuses the essential session cookie below), stores no personal data or IP address, is never shown publicly, and is not shared with any third party.
Cookies and similar storage used here
| Name / provider | Purpose and category | Duration |
|---|---|---|
| PHPSESSID / this website | Essential security session for contact forms, article interactions and the content editor. Also used, only while active, to avoid counting the same reader's visit to an article twice in the internal read count; not advertising. | Session cookie by default. When “Keep me signed in” is selected on the editor login, the editor cookie lasts 30 days and authorization expires after 30 days of inactivity or 90 days from sign-in. Otherwise editor authorization expires after 30 minutes of inactivity or eight hours from sign-in. |
| erg-consent-v1 / local storage | Essential record of category choices, notice version and choice date. | Six months, then choices are requested again. |
| erg-theme / local storage | Functional preference saved only when you change the color theme. | Until you clear site storage. |
| Google sign-in / Google | Optional sign-in resources may use Google-controlled cookies or similar storage to authenticate you. The website holds the returned credential in page memory while you use it. | Google controls its cookie lifetimes; page-memory credentials disappear on reload or sign-out. |
| YouTube and Vimeo / embedded media | Optional players may use provider-controlled storage and receive your IP address and device information. YouTube uses its privacy-enhanced embed domain; Vimeo is requested with do-not-track enabled. These settings are not a guarantee of no processing. | Provider-dependent; consult their privacy policies. |
Managing or withdrawing permission
Use Cookie preferences on any page to change your choices. Saving a withdrawal reloads the page so previously loaded optional scripts stop running and embedded players are removed. It does not undo information already sent, sign you out of Google elsewhere, or delete cookies belonging to another provider. Manage those through the provider or your browser settings. Reject all optional features to withdraw both categories.
If browser storage is unavailable, optional choices apply only to the current page. Without JavaScript, optional integrations remain blocked and policy information remains available. Contact forms still work.
Other services and changes
Google Fonts has been removed from the page’s network requests; the design uses available system fonts. Ordinary external links load another service only when followed. Hosting infrastructure may set additional essential security cookies; their configuration should be reviewed whenever the host changes. Read the Privacy Policy for personal-data practices.
