The Sky Veil
What it is. The veil — a privacy curtain that covers the launcher — is drawn over the sky — your home screen — when the screen wakes. It hides your layout behind a plain sheet until you unlock it.
What it is not. The veil is a seal on the launcher, not device security. Your phone's own lock screen still guards the phone. The veil only keeps your sky private, and it cannot be lifted with the back button.
Turning it on
Turn on "veil when the screen sleeps" at Settings › system › sky veil. After that, the veil appears on its own each time the screen wakes.
Once it is on, the page shows "a curtain over the launcher, not device security — keep your system lock." and how to get through: "TO UNSEAL — draw your sigil, or rest one still finger for 4 seconds". With no talisman inscribed yet, it offers "inscribe a sigil now →".
Seal it on demand. Bind the "seal the sky" action to a gesture or a talisman, and it covers the sky the moment you use it — whether or not "veil when the screen sleeps" is on.
Getting through the veil
There are two ways in, and one always works.
Draw your sigil. Draw the talisman — a gesture shortcut you draw as a shape — you've set as the unseal sign. A clear match lifts the veil; a miss shows "the sky does not know that sign". You choose the sign in the "unseal sigil" picker at Settings › system › sky veil — either "any talisman" or one you name. The picker shows only while the veil switch is on. If you delete the talisman you chose, the picker goes back to "any talisman", so your other talismans still open the veil.
Rest a finger. Hold one still finger on the veil. A ring fills over about four seconds and the veil opens the moment it fills. This always works, even with no sigil set and every label hidden, so the way out is never lost.
What shows on the veil
The veil shows a large clock and a hint line. When a talisman can unseal it, the line reads "draw your sigil to unseal · or rest a finger". When none can — for example, when you have no talisman inscribed — it reads "rest a finger to unseal". The real night sky can show behind it, following your My Sky setting.
The Settings › system › sky veil page holds "veil when the screen sleeps" and, while it is on, the "unseal sigil" picker. There is no switch for the clock or the hint line.
