Secure every Android device you sell on installments — enforce payment fairly, protect your investment, and always keep the customer safe. No more worry about recovery in your mobile-installment business.
Uninstall-proof, factory-reset-proof, tamper-resistant. Runs as Android Device Owner — the strongest control the OS allows.
Auto-locks when an installment is genuinely overdue, and auto-unlocks the moment the customer pays — zero steps for your staff.
Emergency calls always work. Wi-Fi stays on so they can pay. It restricts — it never bricks a phone.
Can't be uninstalled or force-stopped — re-asserted continuously, even on aggressive ROMs: Oppo/ColorOS, Vivo, iQOO, Xiaomi/MIUI, Infinix, Realme and more.
Developer Options, USB debugging and Factory Reset stay locked for the device's financed life — released only when fully paid.
Changing the date or time won't dodge enforcement — a clock change triggers an immediate payment re-check.
Restarting buys no free time. KW Locker re-secures instantly on boot — no gap, no loophole.
Exempts itself from doze/power-saving every cycle, so the phone can't quietly kill enforcement.
Detects SIM swaps and can report device location — invaluable for recovering a device that goes dark.
Six taps on a factory-fresh phone launches Android's QR enrollment — scan and it provisions itself as a managed device.
A portable desktop app installs the locker, sets Device Owner and applies every policy — one click, no setup folder.
Reliable counter-side enrollment, confirmed on Android 14, 15 and 16 — even where store QR flows are restricted.
A staff app enrolls phones wirelessly over ADB — pair with a short code, install, make owner. No cables.
All · Active · Defaulters · Blocked · Released — fast search and filtering across every financed device.
Balance, installments received vs pending, and quick actions — WhatsApp, SMS, locker reminder — on each card.
Full schedule per device, mark paid (cash/online), dated history, clear paid / overdue / due status.
Release a paid device with one online click, or a one-time master code when it's offline.
Super Admin, Owner, Manager, Staff — head-office oversight plus per-shop control and reporting.
Owner status, lockdown, app version, battery, boot, online/last-seen and location — one-tap ping.
Provision at the counter and link to the customer with a signed agreement.
Set the installment plan; the schedule appears in your portal.
Overdue → the device restricts itself. Paid → it unlocks automatically.
Fully paid → release with one click. All control lifts cleanly.
