Lugna is a quiet, private place to write. It's for the days when your mind is full and you need somewhere to put it all down. Lugna helps you begin with gentle, guided questions, or simply lets you write freely. Over time it shows you how you've been feeling, so you can notice patterns, be kinder to yourself, and see how far you've come. And because your journal is yours, Lugna keeps it that way. Your entries are end-to-end encrypted. They're locked with a key that only you hold, not us and not anyone else. You can write honestly, knowing that what you put down stays with you. WHAT YOU CAN DO • WRITE THE WAY THAT FEELS RIGHT Follow guided CBT-inspired prompts when you'd like some direction, or open a blank page and let it pour out. Prefer to talk? Use dictation and speak your mind. • NEVER LOSE A THOUGHT Your draft is saved as you write, even if you switch apps, get interrupted, or your phone rings. Come back and your words are still there. • SEE HOW YOU'VE BEEN Weekly and monthly views show your mood over time, along with your journaling streak, so you can notice what lifts you and what weighs on you. • KEEP IT PRIVATE Protect Lugna with Face ID, Touch ID, or a PIN, and let it lock itself when you look away. Your journal stays behind that lock. • A GENTLE REMINDER Choose a time that suits you, and let Lugna remind you to slow down, check in, and write. • TAKE IT WITH YOU Save your entries whenever you like. Keep them somewhere safe, or share them with someone you trust, like your therapist or caregiver. You also hold a 12-word recovery phrase, like a spare key to your own journal, that only you have. Your mind deserves a safe place to rest. Lugna is that place.
