Shielded.Private by design.
Zcash keeps value in pools. The transparent pool is public like bitcoin; the shielded pools — Orchard, Sapling and the old Sprout — encrypt sender, receiver and amount.
Pool sizes
Only the total in each pool is public. What is inside — who holds it, who paid whom — is not visible to anyone, including us.
Pool sizes are not measured right now: no free public source for them is configured, and we never estimate them. What is in the shielded pools stays private by design — only each pool's total is public, and only a Zcash node reports it.
No pools source is configured on this deployment.

Orchard
The newest shielded pool, introduced with Network Upgrade 5 (2022). It needs no trusted setup and is what Unified Addresses (u1…) prefer.
Sapling
The shielded pool since 2018, behind zs1… addresses. Fast enough for phones, and still widely used.
Transparent
Public t-addresses. Balances and history are visible on the chain, just like bitcoin. Moving funds into a shielded pool is called shielding.
