Questions
Is this creepy?
Not if you tell her. Lunatwin is made for care, not control, and works best when she is in on it.
How accurate is it?
It is based on averages and learns from every period you log. She is always the authority: if she feels different, she is right.
Is it contraception?
No. Lunatwin is not contraception and not medical advice.
What happens to the data?
It is stored in your account, never sold and never used for ads. You can delete everything at any time.
General information, not medical advice. Every body and every cycle is different, and she is always the authority on how she feels. Lunatwin is not contraception and can’t be used to prevent or plan a pregnancy.
