Safety Guide

Use a strong password

Make it long. Mix words and numbers. Do not use your birthday, your UPI PIN, or the password for your email. You will type this password only inside the official app, never on this website.

Do not share codes

• Do not send the password or a one-time code to friends.
• Do not read a code aloud to a caller who claims to be support.
• Do not type either one into a form on a website that copied the Mast79 name.

The login page on this guide explains the steps. It does not collect the password.

Update from the official channel only

Install and update from the channel described on the download page. A file forwarded on a messaging app can be a fake, even when the name looks right. The official size is about 39 MB. The blog explains how to compare a suspicious file.

Lock the phone

Use a screen lock. If you ever open Mast79 on a shared phone, log out before you hand it back. Remove the app from a phone you are giving away.

If something feels wrong

Change the password inside the app, stop playing, and write through Contact Us without including the password. Tell us the phone model and what the screen said. If money left an account you did not mean to use, contact your bank or payment provider as well.
