Sell phones on installments — without the worry

Mavrify is software built for Pakistani mobile shopkeepers. While the customer pays the installments, the phone works normally. When an installment stops, the phone locks. No hardware, no modifications — just one app.

How does it work?

1

Register the phone at the time of sale

Create the customer record in the shop app and install the lock app on the customer's new phone. A few minutes of work.

2

Installment paid — phone works

As long as installments arrive on time, the phone stays completely normal: calls, WhatsApp, banking apps, camera — everything.

3

Installment missed — phone locks

After the grace period the phone locks, and the screen shows only your shop's contact details and a payment message. The moment the installment is received, the phone unlocks.

What does the shopkeeper get?

We are currently in a private pilot phase

The app is not yet open to everyone. We are onboarding shops in small groups so that every shop gets setup and support from our own hands. That is why we cannot reply to every request immediately. Shops that register first get their turn first — and pilot shops get the early (founding) price. The public price will be set higher.

Register your interest — it takes one minute; only your name and WhatsApp number are required, and there is no obligation if you prefer not to give other details. When your turn comes, we will contact you ourselves on WhatsApp.

Frequently asked questionsاردو
Questions shopkeepers often ask
1Can I lock and unlock the phone from my shop?
Yes. Press one button in the shop app — the phone locks or unlocks. The lock or unlock command reaches the phone as soon as it has internet. On the installment due date the lock is applied automatically; that needs neither a separate button press nor internet on the customer's phone.
2What happens if the customer's phone has no internet?
The payment schedule is saved in the phone in advance, so when an installment is missed the lock is applied even without internet. When the customer pays you, you record the amount in your shop app; if the customer's phone has internet it unlocks by itself. If it has no internet, you generate a code in your app and tell it to the customer; the customer enters the code on the phone and it unlocks without internet.
3Can the customer delete the app or reset the phone?
No. The app is installed as the phone's "device owner" — Android's own administrative level. In this mode, deleting the app, force-stopping it, factory reset from settings, safe mode and USB debugging are all disabled.
4Can anyone bypass the lock?
The honest answer: no lock software in the world is 100% unbeatable. For an ordinary customer it is practically impossible. If someone has a repair shop replace the entire Android software (flash), the phone disappears from the system — the moment that happens you get an alert, and the record stays with you. This is the limit of every lock app.
5What does the customer see when the phone is locked?
A screen appears on the phone that cannot be dismissed, showing your shop's name, contact number and the outstanding installment. Emergency calls stay open. As soon as the installment is received, the phone immediately returns to normal.
6While installments are being paid on time, is there any restriction on the phone?
No. Calls, WhatsApp, banking apps (Easypaisa, JazzCash, etc.), camera, games — everything works normally. The phone does not slow down and the battery does not drain. The customer only receives installment reminders.
7Does the customer get installment reminders automatically?
Yes. Before the due date, reminder messages go to the customer's phone automatically. You can also send your own message (for example, "Please come to the shop tomorrow and pay your installment") — the customer sees it both as a notification and inside the lock app.
8Can the phone lock at night as well?
No. No new lock is applied during night hours. The customer's sleep and emergencies are taken into account; locks are applied during the day.

Frequently asked questions (continued)
9Does the app on the customer's phone see their photos, location or messages?
Never. The app does not open the gallery, does not take location, and does not read messages or email. It has only one job: lock the phone when an installment stops. The customer's privacy stays fully protected — which is also good for your shop's reputation.
10How do the agreement and guarantors work?
At the time of sale the customer signs digitally right in the shop app — or gives a thumbprint if they cannot read. The app creates a legal agreement that can also be sent to the customer on WhatsApp. You can add two guarantors as well: name, phone number, CNIC and their own signed agreement. If the customer does not pay, the guarantor is legally responsible.
11Which phones does it work on?
Android 11 and above — Tecno, Infinix, itel, Vivo, Oppo, Realme, Xiaomi/Redmi, Samsung and others. We test every model on a real phone before adding it. No lock app can run on iPhone.
12How long does phone setup take?
Setup needs only two things: your shop phone with the shop app, and the customer's new phone. Before handing over the new phone, one app is installed on it in a few minutes — it installs automatically from the shop app. No computer is needed and nothing is difficult. The customer's phone can be new or used; both work. We teach you ourselves the first time.
13What happens when the customer pays all installments in full?
"Release" from the shop app — the app on the customer's phone removes its control completely and the phone becomes free. The phone is now fully the customer's own; nobody retains any right to control it. The customer's complete record, however, stays with you.
14What if the shop phone is lost or replaced?
All records are kept safely on our server. Log in on the new phone — everything comes back. A shop can also run more than one phone (owner, salesman, collector).
15What happens to the customer's CNIC and photo?
This data is stored encrypted (in secret code) and only your shop can see it. Once the customer has paid all installments, all CNIC data is deleted 90 days after release.
16What is the price?
During the pilot the price is kept quite low. Shops in the pilot get the early (founding) price, which will be lower than the later price. Register, and we will share the details when your turn comes.

If your question is not here, write it in the "Any questions for us?" box on the registration form — we will answer when we get in touch.

Register: just your name and WhatsApp number — one minute.
