Appearance preference
The dtsoft-appearance local-storage key remembers a light or dark appearance when you choose it. Without a saved preference, the site follows your system. This preference remains until you change it or clear site data. It is not an advertising identifier and is not sent to us by this feature.
Other services
The current site code does not set advertising or analytics cookies. Hosting security may use technical mechanisms to deliver and protect requests. Following email, WhatsApp, GitHub or LinkedIn links takes you to services with their own cookie and storage policies.
Managing browser data
You can clear website data and control cookies in your browser. This can reset preferences, sign you out or permanently remove records stored only on this device. Export anything you want to keep first. Browser storage controls are separate from deleting data already held on a server or in an exported file.
