## Privacy choices
A fresh install or an upgrade without a prior choice shows the privacy notice
before signaling registration. Declining leaves settings, local history and the

A launch without stored consent shows the privacy notice before signaling
registration, including after a previous refusal or withdrawal. Returning from
the background also shows it until consent is granted. Declining dismisses it
for the current visit and leaves settings, local history and the bundled
privacy policy available. Settings → Privacy → Privacy and Authorization shows consent status and can
withdraw consent to stop both the persistent identity peer and remote session. Consent is required
again before reconnecting; foregrounding or relaunching does not grant it.
The notice opens as a native large sheet with a scrolling document above a fixed
consent area. The agreement checkbox starts unchecked; **同意并继续** stays
disabled until it is selected and the bundled policy is available.
**暂不同意** dismisses the sheet for this visit. Swipe-to-dismiss is disabled
so either action is explicit.
Remote desktop previews default to off, including on upgrade. Enabling and

session indicator remains visible while saving is enabled. Previews stay local
confirming saving in Settings → Privacy applies from the next connection. Previews stay local
and are excluded from device backups. Disabling saving or withdrawing consent
clears them; clearing is serialized after pending writes to prevent resurrection.
Old previews saved without this choice are removed on upgrade.

Network status samples and caches displayed measurements once per second while
the panel is open; video-frame redraws reuse that snapshot. Traffic and connection RTT
expire after three seconds without a valid report; RTT uses the desktop's
0.25-weight smoothing. FPS counts distinct frames submitted to the native
display layer during the last second. Video delay averages calibrated capture
time through display submission over that same window; it is an estimate, not
a measurement of physical screen presentation. Missing calibration or stale
samples show **—**, and idle video reaches zero FPS. Switching displays or
backgrounding clears video samples; disconnecting clears all statistics.
Receive loss rates are fractions converted to percentages. As on desktop,
MiniRTC's total loss is the sum of the media loss rates, not a packet-weighted
overall loss rate.
For black-screen diagnosis, keep Xcode's debug console open and look for
`CrossDesk` and `VideoToolbox` messages. With VideoToolbox H.264 decoding selected, look for
`VideoToolbox decoded frame` from MiniRTC and `CrossDesk delivered latest frame`
