If the cost is the problem
Women staying in A2E housing have the full program free. Nobody is asked to prove anything, and there is no code to enter.
If you are not in housing and the $5 is genuinely what is stopping you, say so here. It goes to Ashes to Exodus and someone will sort it out with you. It is a real offer.
Asking about the cost needs a free account
Not a payment — an account. It exists so your place is kept when you come back on a different phone, and so this library knows which parts you have worked through.
It takes a minute, asks for an email address and nothing else, and never asks for your real name.
Stages 1 and 2 stay readable with no account at all, and always will.
Stages 1 and 2, and everything in the Resources tab, stay free and open to you regardless — with or without an account, and whatever you decide about this.
