## What is Petalline?

No account. No cloud. No ads. No subscription. Your journal never leaves your iPhone — and we built it so it literally can't.

Petalline is a calm, private space to check in with yourself each day: how you feel, your energy, how you slept, a few tags, and a line or two. Everything is encrypted on your device with a key only you hold.

A GENTLE DAILY CHECK-IN
• Log mood, energy, sleep and tags in seconds.
• A quiet streak keeps the habit alive — no guilt, no nagging.
• Missed a day? Backfill any date from the calendar.

SEE YOUR MOODS TAKE SHAPE
• A month-at-a-glance heatmap colors each day by how you felt.
• Mood-over-time charts and tag correlations show what lifts you — and what weighs on you.

PATTERNS, FOUND ON YOUR DEVICE
• On-device AI writes warm, private reflections on your week. No cloud, no API, nothing uploaded.
• Every statistic is computed locally. We never see a single word.

PRIVATE BY DESIGN
• End-to-end encrypted with AES-256. The disk only ever holds ciphertext.
• No account, no tracking, no analytics, no third-party SDKs.
• Export a passphrase-protected backup — or a readable Markdown copy — anytime.
• Optional Face ID / passcode lock, and a Home Screen widget that shows only your streak, never your words.

ONE PAYMENT. YOURS FOREVER.
Unlock insights, on-device reflections and encrypted export with a single purchase. No subscription, ever — and every future update is included.

Made for anyone who wants to understand themselves a little better, without handing their inner life to a company.
