There are two sides to the transaction. The lender is offering a fixed rate loan for 30 years, with no option to call for early repayment. However, the borrower does have the option to repay early at their discretion. In exchange for this massive assymetry, the borrower pays a premium of about 60 basis points over an adjustable rate with 5 year initial rate lock.
Broadly speaking, this product makes no sense. If interest rates go up, the value of the loan goes down. If interest rates go down, the value of the loan goes up ... until the borrower unilaterally refinances and pays of the loan at face value.
Indeed, no bank actually holds fixed rate loans. Instead they immediately sell it to Fannie May/Freddie Mac, which were created by the government specifically to allow for a product as absurd as the 30 year fixed rate mortgage to exist.
