## What is Cairn?

Cairn is a quiet, private companion for quitting porn.

A cairn is a stack of stones left on a hard trail to show the next person the way. In Cairn, you build one. Every day you show up, every check-in, every urge you get through adds a stone. A slip adds a weathered stone: dark, worn, still part of the structure. Nothing you build is ever taken away.

NO ACCOUNT. NO EMAIL.
Cairn doesn't ask who you are. There is no sign-up, no password and no real name. Your history is tied to your install, not to an identity. You can erase everything from Settings whenever you want.

FREE, FOR REAL
• Your cairn: the heart of the app, free
• Daily check-ins for mood, energy and urge level
• Emergency Mode: grounding tools for the hard moment, always free
• Journal with a daily prompt
• Slip debriefs: log what happened without losing anything
• One small mission a day
• Progress: honest weekly summaries worked out from your own data. Nothing here is a prediction.

CAIRN PREMIUM (OPTIONAL)
• Rowan, an AI coach you can talk to at any hour. Rowan is an AI, not a person and not a therapist.
• Search across every journal entry
• Your busiest hours, from your own urge history

HONEST BY DESIGN
No invented statistics, no fake testimonials, no free-trial tricks. You see the price before you buy, and you can cancel in two taps from your Apple Account.
