Appearance preference
Automatic appearance uses the time zone reported by your browser: light from 07:00 to 18:59 and dark outside those hours. We do not request your location. You can choose Automatic, Light, Dark or Colour-friendly. The selected mode is stored under arvellan-theme in local storage and remembered on later visits; it is not used for advertising or cross-site tracking. Select Automatic or clear your browser’s website data to reset a manual choice.
Cookies & hosting
Arvellan does not add advertising cookies or optional analytics in this version. The ChatGPT Sites platform and infrastructure providers may use essential authentication, routing, abuse-prevention and security mechanisms as appropriate to access and delivery of the hosted service. A private preview may require ChatGPT sign-in. These platform functions are separate from any optional marketing service.
Maps, fonts & images
The maps are drawn within this website from locally served geographic data. They do not automatically load Google Maps or another map provider. Fonts use your device’s system font stack. Image and icon assets are served with the website rather than through a third-party tracking embed. Selecting View location opens Google Maps and is then subject to Google’s terms and privacy practices.
Retailers & social networks
Links to Amazon, Kobo, Google Play, Gumroad, Türkiye Kitabevi, Montcael and social networks take you to external sites. Visiting this page does not itself load their embedded widgets or send a form submission to them. When you follow a link, the destination controls its own storage and processing. External links are marked where they appear as text; social links have accessible names.
If optional services are introduced
Any future non-essential analytics, advertising or embedded content requiring consent must remain disabled until a valid choice is made. Consent must be as easy to refuse or withdraw as to give. We will update this page to describe the actual provider, purpose and storage duration before introducing such services.
