Nalu is a private mood and symptom journal that learns your personal "low tide" — the hard days before your period — and warns you ahead of time.
Email nikitachirkun@gmail.com — we usually reply within two working days.
Where is my data? On your iPhone, and in your encrypted iCloud backup if you use one. There is no account and no Nalu server. Use Settings → Your data → Export to save a copy.
I don't have periods (IUD, implant, continuous pill). Can I use Nalu? Yes. Choose "No periods" and mark when your hard days start; Nalu learns the rhythm from those marks.
Do I have to track my cycle? No. Nalu also finds patterns from sleep and the things you tag, with or without a cycle.
How do I cancel my subscription? iPhone Settings → your name → Subscriptions → Nalu Pro.
Is Nalu medical advice? No. It's a self-reflection tool and can't be used for contraception or diagnosis.
