n your bag, under your car — what if there's a tracker that isn't yours? TagGuard finds hidden Bluetooth trackers (AirTag, Galaxy SmartTag, Tile, Chipolo, Google Find My) and makes sure your family knows the moment something is wrong. ■ Hidden tracker detection • One-tap scan — results in seconds • Risk score — sightings, time together, distance traveled and distinct places are computed so you're only warned about real threats • Radar finder — the gauge climbs and vibration speeds up as you get closer; find it under the couch or inside the car • Route evidence — every shared movement is mapped, ready to reference in a police report ■ Family safety net (optional) • When tracking risk is detected, connected family members are alerted automatically — even before you notice • SOS — hold for 2 seconds to share your live location with family • SOS location texts reach family even without the app • Everything is end-to-end encrypted — even our server can't read it ■ Caring for parents • Connect with a single 6-digit code (no sign-up) • Once a parent turns on consent, you can request their location whenever you're worried • Every share posts a notification on the parent's phone — this is not covert monitoring ■ Privacy principles • Tracker detection runs 100% on your phone • Location leaves your phone only for family sharing you start yourself (end-to-end encrypted) • No ads. No account. Free to start.
