Terms

The service

Backplane provides written lessons, diagrams, videos, quizzes and drills about system design, low-level design and core computer science. The Core CS track and the Foundations stage of every other track are free; Pro content requires a paid plan once Pro is available.

Content is for your personal learning. You may not resell, redistribute or scrape it, or remove attribution from it.

Accounts and payment

You are responsible for activity under your account. One account is for one person.

Pro is billed monthly or yearly in advance and can be cancelled at any time; access continues to the end of the paid period. Refunds within 14 days of a first purchase are granted on request.

No guarantees

We work hard to keep the material accurate, but it is provided as is. Interview outcomes depend on you; we do not promise offers, and the service is not a substitute for professional advice.

Our liability to you is limited to the amount you paid us in the twelve months before a claim.

Changes

We may update these terms. Material changes are announced in the product before they take effect.
