WhatsApp groups leak people. Locksee groups stay sealed

People together with phones, identities kept private

In many phone-number groups you can browse profiles. Group calls can show numbers. Locksee does neither.

Think about the last big WhatsApp group you were added to. Housing. School. A wedding. You can often tap a name and see a photo, a number, a way out to their chat. The group was a room. It also became a directory.

The quiet leak in group calls

Add someone to a WhatsApp-style group call and the room can pick up a number they never meant to publish there. You invited a voice. The app invited a SIM.

That is how a private call becomes a contact-harvesting event. Nobody has to be malicious. The design does the work.

What sealed means on Locksee

Adding someone to a Locksee group or group call does not hand the room their number, profile, or QR. Members are not a browseable list. You invited a person — not a public card.

That pairs with QR identity. There is no phone book to leak because the phone book was never the product.

When a group still makes sense

Project teams. Family trips. A circle that should stay small. Use groups when the point is the conversation, not the address book. If someone should not be able to add you, per-chat group permission can close that too.
