Block
documentation.

The product's scope in brief: what the word irreversible covers and how the product reaches the market.

What "irreversible" means

The word is strong and is worth explaining what it covers.

No unblock in the app

Neither the user, nor the buying company, nor support can undo the block from inside the program.
Resistance, not impossibility

The product creates real resistance. The full conditions are in the Terms of use.
Refund separate from the block

Getting your money back is a right. Undoing the block is not part of the refund.
Warning and confirmation

A warning screen before activation and a typed confirmation are part of the product, not just the interface.

The terms that appear on the page and in support.

Project terms
