Founder portrait

Students work hard, but still forget what they studied.

The system rewards short-term cramming and leaves us alone when it matters.

I refuse to accept that.

Custom Backup exists to help students remember for life.

Still 17. Still building.

Trusted where it matters.

Custom Backup is a revision support tool created by a Year 13 student. Feel free to scan the QR code and check the resources out.
