Pick the most recent .ibt — named with car, track, and date.
Out-lap or formation-lap files are too short (<500 KB). If you see “session too short”, pick a longer session file.

Your telemetry stays yours. We store only consolidated lap statistics - never raw session data, never sold, never shared with third parties. Your email is used solely to deliver reports and track your credit balance — never shown on any card, never used for advertising. Spotter is free because real reports help us show what PitDelta does: your Quick Debrief card may occasionally appear as an anonymous product example, with track and car names removed. Your name and email are never displayed. Yellow and Purple reports are always private and never used in marketing.
