Fair questions. Straight answers.

No. SpeedGuardian Pro contains no radar or laser detection and no police-location features. It shows you the posted speed limit — public road-sign information — and previews the speed zones ahead on your route. The goal is a clean record, not evasion.

Professional map data from HERE Technologies — the same class of data many built-in car navigation systems use — with OpenStreetMap as a fallback on rural roads. When no data exists for a road, the app shows '--' and stays quiet rather than guessing.

Strong on highways and in metro areas; honest about gaps on rural roads and in school zones with time-of-day limits. Construction zones and temporary limits are a hard no — see the next question. When the app and a posted sign disagree, the posted sign is always right — the app tells you this too.

No — and it won't. SpeedGuardian Pro reads the permanent posted speed limit from map data. Temporary limits — construction zones, work-zone reductions, incident and event signage, anything on an orange or portable sign — are not in that data, so the app cannot see them and will not warn you about them. During construction the app keeps showing the road's normal permanent limit. When you see orange, the signs on the road are the law and they override the app completely — slow down, and remember work-zone fines are typically doubled. This is a limitation of every map-data speed app; we'd rather say it plainly than let you find out in a work zone.

It stays on your phone. Limit lookups send coordinates to the map provider for the lookup only — no identity attached, nothing stored by us. Driving events for your weekly report live on the device and are deleted when you delete the app. No account, no ads, no third-party analytics.

Structurally, not just by promise. Google Maps and Waze tie every drive to your Google account — your location history is logged, profiled, and monetized; that's why they're free. SpeedGuardian Pro has no accounts at all, runs no servers that store user data, and ships zero ad or analytics SDKs — our App Store privacy label shows location only, anonymous and never linked to your identity, with no tracking section at all. There is no database of your drives to breach, subpoena, or sell, because it was never built.

The subscription. You pay for the product, so you aren't the product. Free navigation apps are advertising businesses that need to know who you are and where you go; we're a driver-protection tool that deliberately can't. That trade — a few dollars a month for a navigator with no memory of you — is the whole point.

Yes. SpeedGuardian Pro runs in the background: alerts fire with the screen off, the phone locked, or any other app in front — Google Maps, Waze, Spotify, whatever. Voice alerts duck your music for a moment and never interrupt phone calls, and they play through your car's speakers over Bluetooth or CarPlay audio.

Yes — right now, on 1.0. Plug into CarPlay (wired is more stable than wireless) and the head unit shows a live guard panel: the current posted limit, your speed (red the moment you're over), the next speed-zone change, and the next turn. Voice alerts play through your car audio the whole drive. Apple granted the CarPlay navigation entitlement in August 2026, and 1.1 brings the full-screen map with turn-by-turn arrows and ETA to the car screen — that update is in Apple review.

No — the app looks up posted speed-limit data over the internet, so when you lose cellular or Wi-Fi (remote highways, canyons, tunnels, dead zones), the current-limit display goes to ‘--’ and alerts pause for zones we can’t look up. On a locked route the app prefetches the whole corridor’s limits at the start of the drive, so brief dead zones along a planned route usually don’t interrupt guarding. We can’t be held responsible for missed alerts caused by coverage gaps, so plan accordingly on remote drives. Road-trip fix: a Starlink Mini in the car keeps the whole drive online — get a free month of Starlink here.

iPhone gotcha we hit in the wild: if your phone remembers the Starlink SSID, it'll auto-join the router the moment you're in range — even if the dish is unplugged or stowed. From the phone's perspective it has Wi-Fi, so it won't fall back to cellular, and every app that needs the internet (SpeedGuardian Pro, Google Maps rerouting, everything) silently breaks. Fix: on the iPhone go to Settings → Wi-Fi → tap the (i) next to your Starlink network → turn Auto-Join OFF, or Forget Network when you're not actively using the dish. Same trap applies to any parked-vehicle or trailer Wi-Fi you don't want the phone reaching for.

Wireless CarPlay is finicky, especially when Bluetooth is trying to pair the same phone in parallel — you end up with call audio on Bluetooth and app audio on CarPlay at the same time. Two-part fix that worked for us: (1) in your car's Bluetooth menu, Forget Device for the iPhone entry — CarPlay handles call audio on its own; (2) plug in via USB (wired CarPlay) instead of relying on wireless. Wired is more stable and connects instantly the moment you're in the car. Turning on Wi-Fi Calling on the iPhone helps calls route cleanly in low-signal spots too.

Yes — worldwide from day one. We verified live posted-limit coverage in the UK, Germany, France, Canada, Australia, Japan, and Mexico, alongside deep US coverage including rural highways. The app follows your device's units automatically (km/h in metric countries, mph in the US) and you can override either way in Settings.

Completely. Set your over-limit threshold (0, 5, 10, or 15 over), toggle spoken limits on or off, or set zone announcements to 'drops only' — so it stays quiet through routine changes and only speaks up for sudden drops of 10, 15, or 20+ mph, the small-town-ambush case. Voice-only mode flips it the other way: all voice, no screen.

Yes — Family Sharing covers up to six family members on one subscription. Set the alert threshold together as a family agreement, and use the weekly report as a coaching tool. The teen sees the same data you do; it's a shared standard, not surveillance.

It uses the same navigation-grade location mode as maps apps. Expect battery usage comparable to running turn-by-turn navigation. A car charger or mount with power is recommended for long drives, same as any nav app.

Not yet. SpeedGuardian Pro is iPhone-first (iOS 18 and later). Android is on the roadmap after CarPlay ships.

Through Apple, in about ten seconds: Settings → your Apple ID → Subscriptions → SpeedGuardian Pro → Cancel. If you cancel during the 7-day trial at least 24 hours before it ends, you pay nothing.
