Protected lessons, fair for everyone
Mr. Salah’s lessons are made for the students who join the class. Here’s how they stay that way.
-
Official app only.
Lessons are encrypted and play only in the Salah Bahzad app. There’s no file to pass around.
-
Your name on the video.
Your name and student ID move across every lesson you watch.
-
No screenshots, no screen recordings.
They come out black. In the app, on supported devices.
-
A set number of views.
Each video shows how many views you have left, and a view only counts once the video actually starts.
-
One device on the portal.
Your account stays yours: one device at a time, and you can switch devices yourself from your profile.

For parents: what you should know
Real, approved students only. Every registration needs a parent’s phone number and an ID photo, and Mr. Salah’s team reviews it before the student can sign in.
You’re the contact on file. The team has your number and can contact you about your child’s enrolment, attendance or results.
A clear weekly routine. Your child always sees what to study next: videos, then the assignment, then the quiz. Ask them to show you their progress and scores; it’s all on their screen.
No online payments, nothing that renews. Sessions are unlocked with prepaid code cards bought from [TBD: where]. The price is shown before a code is used, and no card details are ever entered.
Private by design. ID photos are never public; only staff who need them can open them, and every view is logged. Your child can delete the account at any time.

Got questions?
Getting started
Is signing up free?
Yes. Creating an account is free. You only pay when you redeem a code to unlock a session.
Why do you need a parent’s phone number and an ID photo?
So Mr. Salah’s team can check every student is real and reach a parent if needed. Your ID photo is private and only seen by the staff who need it.
How long does approval take?
[TBD]. A person reviews every account. Sign in to check your status; if something’s missing you’ll see why, and you can fix it and resubmit.
Codes & access
Where do I get a code, and how much is it?
[TBD: outlets and prices]. Each session shows its price before you redeem. A code works for any session priced at or below its value; no change is given.
What happens when my access ends?
The videos and quiz lock, but your assignment and notes stay open. Redeem another code to extend your access.
The app & devices
Can I watch lessons in my browser?
No. Lessons only play in the Salah Bahzad app, so they stay protected. Sign-up, codes, assignments and quizzes all work in any browser.
Which devices can I watch on?
Today: Windows 10 (version 2004 or newer) and Windows 11. Android, iPhone, iPad and Mac are coming soon. You’ll need an internet connection.
Why only one device on the portal?
To keep each account for one student. You can switch devices yourself from your profile, up to [5] times a year; after that, call the team.
How many times can I watch each video?
Each video has a set number of views, shown next to it. A view only counts when the video actually starts in the app.
Can I download lessons to watch offline?
No. Lessons stream over the internet and can’t be downloaded; that’s part of keeping them protected.
Studying & account
How do the quizzes work?
Some sessions start with a timed quiz on the session before. Do it in one sitting: leaving uses up the attempt. Your best score counts, and you can review your answers afterwards.
Is the platform in Arabic?
Lessons are taught in [TBD: language]. The portal and app screens are in English for now.
How do I delete my account?
From your profile, choose Delete account, or follow the steps at app.mrsalahbahzad.com/account-deletion. Deleting is permanent.
How do I contact you?
Call +20 112 311 6565 [TBD: hours]. [TBD: WhatsApp]
