End-to-end encryption means no one — not hackers, not government officials, not the company that owns your device — can read your message while it's being sent. It basically takes your message, jumbles it up, sends it, and unjumbles it once it reaches your recipient. So anyone who tries to intercept your message in between you and your recipient just gets a bunch of mess instead of the message itself. This is important because messages can pass through loads of hands on their way from sender to recipient, such as the service you use to send the message, the internet service providers involved, and servers that store the message data for any amount of time.

For the Poincaré half-space model in dimension 2, the metric evaluates on the coordinate tangent vectors \(\frac{\partial}{\partial x}, \frac{\partial}{\partial y} \in T_pM\) as \[g_p\!\left(\frac{\partial}{\partial x^i}\bigg|_p,\;\frac{\partial}{\partial x^j}\bigg|_p\right) = \frac{1}{y^2}\,\delta_{ij},\] i.e. the coordinate tangent vectors are orthogonal and each has length \(\frac{1}{y}\) — shrinking to zero as \(p\) approaches the boundary \(y\to 0\), which is what makes the space “infinitely large” near the boundary.
