Educational courses app (videos)

We're looking to create an app for education courses (videos) for students, the access to the content of the app will be through entering a serial number password which we see in the forme of Scratch off Cards for subscriptions raging from 1-12 months.

Summary:
-Sign up / sign in
-App content is locked with the option to enter a serial number to unlock the features
-Only content that's not locked is a video promotion of the courses
- After unlock, you will see categories for the courses
- Each course contains around 20-30 educational videos

Content :
- Videos will be up on Viméo (can be changed) and embedded
- When video is playing, you have information (text) below the video.
- below the video will be a section -Exercise- which has a question and click to see -Answer-
- Admin can add categories/courses/videos and can remove them
- Admin can remove access/block a user


Unlocking the content:
- App can be unlocked with serial number (SN)
- We can add and delete SN in the database (we already have a system that gives us SN
- There are SN for 1/3/6/12 month subscription
- After subscription ends app is locked again
- If user attempts to enter a wrong SN 20 times in 24 hours his account is blocked (email blocked)


Live videos:
- There is a Category for live content
- Live videos will be up on Viméo (we accept to change platform if there's an issue)
- When clicking on live category, there is a schedule for live content
Example:
02/07/2023 17:00 Live / Course name
