Privacy Policy

Last updated: 15 August 2026

Who we are

Recharge4Me is published by LumiTek Exchange (Private) Limited, a company registered in Zimbabwe, of 5162 Mkoba 15, Gweru, Zimbabwe. Questions about this policy go to privacy@lumitekexchange.co.zw.

What the app collects

Nothing. Recharge4Me has no servers. It does not create an account for you, does not ask for your name, number or email, and sends no information to us at any point. We have no way of knowing who uses the app or how often.

What stays on your phone

Some information is kept locally so the app can work. It is stored in the app's private storage on your device, and it is never transmitted.

• Camera images. When you scan a card, the photo is analysed on the device to read the digits. It is not uploaded, and it is not kept in your photo library.
• Recharge history. For each recharge the app records the network, the date and time, whether it succeeded, the last four digits of the PIN, and a one-way fingerprint of the full PIN. The full PIN is never written to storage. The fingerprint exists only so the app can warn you when you scan a card you have already used; it cannot be turned back into a PIN.
• Your settings. Whether vibration is on, your default network, and whether you have seen the introduction.

You can erase all of it at any time from Settings → Clear recharge history, or by uninstalling the app.

Permissions, and why

• Camera — to read the numbers on the card. Used only while the scan screen is open.
• Phone (Android) — sending a recharge code is technically a phone call, so Android requires this permission for the app to send it. Decline it and the app opens your dialer instead.
• Phone state (Android) — to list the SIMs in a dual-SIM phone so you can choose which line to credit. It reads only SIM names and slots.

Where your recharge code goes

When you recharge, the code is sent to your own mobile network over the normal telephone network, exactly as it would be if you typed it into your dialer. It does not pass through us. What your network does with it is governed by that operator's own privacy policy and terms.

Text recognition

Reading the digits uses Google ML Kit's on-device text recognition. The model runs entirely on your phone and card images are not sent to Google or to anyone else.

Mailing list

If you enter your email address on our website to hear about updates, we hold that address so we can write to you. This is the only personal information we ever hold, and only if you gave it to us deliberately.

• We confirm the address first. You are not added until you click the link in the confirmation email, so nobody can subscribe you.
• We use it to send occasional updates about Recharge4Me. Nothing else.
• Every email has an unsubscribe link, and it works immediately.
• We do not sell, rent or share the list with anyone.
• The list is held by our mailing provider on our behalf, under their own security and privacy terms.
• Ask us to delete your address and we will, and it will not be kept.

The app does not collect your email address and never asks for it. Subscribing is entirely separate from using Recharge4Me.

Children

Recharge4Me is a general-purpose utility and is not directed at children. We do not knowingly collect information from anyone, of any age.

Your rights

Data protection law, including Zimbabwe's Data Protection Act, gives you rights to access, correct and delete personal information held about you. Because we hold none, there is nothing for us to produce or erase. The information on your own device is under your control and can be deleted from within the app.

Changes

If this policy changes we will update this page and the date above. If a future version of the app ever collected anything, we would say so here and in the app before it did.
