Put a private proxy on your own Cloudflare account. From this phone, in about a minute. Nothing is stored here and no account of ours is involved.
Create one at dash.cloudflare.com using the Edit Cloudflare Workers template.

gone the moment you close the tab.
Paste either one into v2rayNG, NekoBox, Hiddify, sing-box or any
VLESS client. The subscription URL keeps working if you add more endpoints later.
