Yeah, it only works if you have cookies enabled(works with js disabled). You could use containers or CookieAutoDelete if you use firefox to auto delete cookies later. Or just configure the browser to be on incognito mode always with only third-party cookies disabled.
Itunes can also sync over Wifi[1] or You can use Nextcloud[2]. You can backup your photos to your PC/Mac and then upload them to a cloud service. I use duplicati[3], it automatically encrypts and compress your files and uploads them to the cloud service of your choosing. I use Backblaze B2 for the cloud service($0.005/GB)[4].
