A complete deterrent system — built privacy-first, designed to feel like a native iPhone app, and ready to protect a whole family.
A secret 4–6 digit PIN stored as a one-way hash — never in plain text. Completely separate from the real iPhone passcode, so a thief can't tell the two apart. Entering it silently triggers the wipe simulation and alerts.
A pixel-accurate replica of the iOS lock screen — time, date and PIN pad. The thief sees a normal locked iPhone; the emergency PIN launches the deterrent sequence instead of unlocking anything.
A staged ~20-second erase with percentage counter, spinner and authentic system-style messages, ending on “Reset Complete.” Convinces the thief the phone is bricked — no real data is ever touched.
The moment the emergency PIN fires, every trusted contact receives an immediate email — device label, owner name and timestamp. Contacts are stored per-user and fully manageable.
Optionally capture exact GPS coordinates at the instant the PIN is entered, embedded as a live Google Maps link in the alert — giving contacts or law enforcement the thief's last known location.
Send a test notification to all trusted contacts at any time — without triggering the wipe simulation — to confirm the alert pipeline works before a real emergency.
A step-by-step in-app guide uses iOS Guided Access to lock the device to the SENTINEL screen — so a thief meets the decoy, not the real iOS lock screen.
Prevents Auto-Lock from engaging while active, keeping the decoy live for a user-set 1–120 minutes so the screen never goes dark and reveals iOS underneath.
A hidden gesture — 3–10 rapid taps in the top-right corner — exits the simulator. The time window scales with tap count, making accidental discovery virtually impossible.
Swipe-up exit works only on the post-wipe screen; it's disabled on live screens. The “Exit Simulator” button is rendered black-on-black — invisible unless you know it's there.
Create a named security group and invite members by email invite code. Everyone in the group shares the same protection model — ideal for families and small teams.
Group admins see every member device, its PIN-configuration status, and a live feed of recent wipe events across the group — centralized oversight at a glance.
Two roles — Admin (full visibility, event logs, member management) and Member (personal PIN and contacts). Enforced at the database level via row-level security.
Emergency PINs are one-way hashed before saving — never held in plain text, even by the app.
All entity data is isolated by row-level security; users can only ever access their own records.
Location is captured only at trigger time, and only if the user opts in — never passively tracked.
Deleting an account wipes everything — device profile, trusted contacts and event history.
Each device gets a custom label used in every alert — multi-device families stay easy to manage.
Full theme support with persistent preference — dark for the decoy aesthetic, light for everyday settings.
Native-feeling pull-to-refresh on dashboard and log screens keeps status and event history current.
Respects safe-area insets, disables overscroll bounce and tap highlights — behaves like a first-party app.
Choose a single licence, a 3-account pack, or a family pack of 5 — and set up your decoy in minutes.
