+"""Anonymous analytics for Frame Control, sent to PostHog. Python stdlib only.
+
+Three levels, each chosen in the page's Privacy panel (docs/privacy.md lists
+every event and property):
+
+- usage (on by default, after the first-run notice has been shown): installs of
+ Frame Control, daily opens, updates, which tabs are used, and whether installs
+ on the Frame worked, with an error category from a fixed list. Never file
+ names, paths, hostnames, IP addresses, window titles or account data.
+- compat (opt-in): Android compatibility reports, the same fields the Report
+ dialog shows, so they reach the shared database (frame_compat_db.py). The
+ maintainer's sync (python3 ui/frame_compat_db.py sync) moves them there.
+- diagnostics (opt-in): error messages and Python tracebacks, scrubbed of
+ home folders, user names, addresses and keys.
+
+The first-run notice offers compat and diagnostics together, and the page's
+Report a problem dialog (frame_report.py) sends bug reports privately to the
+same project whatever is chosen here.
+
+Events are identified by a random id made on first run, not by the person or
+computer, and sent without person profiles or GeoIP. Nothing is sent without a
+project key (ui/telemetry.json or $FRAME_CONTROL_POSTHOG_KEY), from a source
+checkout unless $FRAME_CONTROL_TELEMETRY=1, or when $DO_NOT_TRACK=1 or
+$FRAME_CONTROL_TELEMETRY=0.
+
+Events wait in an outbox file and are sent in batches from a background thread,
+so going offline loses nothing. The last SENT_KEEP sent events are kept on this
+computer so the page can show exactly what left it.
