A collector profile needs a clear public boundary

Void Cards remains an idea I am considering, including whether Telegram would be its entry point. A public collection could be part of its appeal. That makes privacy an early design question: which parts of a person's participation would another visitor see?

I would separate the account used to access the service from the identity shown beside a card. A public label such as "Collector #7E21" could identify a collection without displaying the person's Telegram username. An optional alias could replace that label. Neither choice would mean the operator knows nothing about the account, so I would avoid calling the arrangement anonymous without explaining that distinction.

The useful check is to preview the public page as a visitor. Does it reveal a profile link, an avatar, an imported biography, or a timestamp that the collector did not expect to share? An alias offers little protection if the surrounding interface quietly publishes identifying details. I would limit the default public fields and ask separately before adding more.

Personalized cards would need another decision. A face, nickname or biography can identify somebody even when the owner label is generic. If photo-based cards become part of the design, I would want a preview and a separate choice about public display before accepting a request. I would also need a clear policy for retaining and deleting submitted material.

My review question would be: can someone explain what visitors see, what the operator retains and what they can change later? Those are three separate answers that a single privacy toggle cannot provide.
