## What is ColdKeeper?

ColdKeeper is the simple, beautiful timer for cold therapy. Whether you're starting your first cold shower or running structured Wim Hof sessions, ColdKeeper turns every plunge into measurable progress.

Designed for hands you can barely feel. Big tap targets. Strong haptics. Audio cues that get through closed eyes and a hood. No fiddling, no menus, no distractions when you're under the cold.

— FOUR SESSION TYPES —
• Ice Bath
• Cold Shower
• Open Water Swim
• Contrast Therapy

Pick a type, log the temperature (optional), tap the giant START button, and ColdKeeper handles the rest.

— GUIDED PROTOCOLS —
• Beginner Ramp — 30s → 60s → 2min over four weeks. The proven on-ramp.
• Wim Hof — guided breath rounds plus immersion. Follow along, no YouTube.
• Contrast Therapy — automatic hot/cold alternation, athlete-style recovery.
• Custom (Pro) — design your own intervals.

— DEEP HISTORY & STATS —
Every session is saved with date, type, duration and water temperature. See your streak, total time under the cold, longest plunge, and weekly trend at a glance. Free tier keeps the last 7 days. Pro keeps everything, forever.

— APPLE HEALTH —
Sessions write to the Health app as "Cold Water Immersion" workouts (Pro). Your data stays on-device — ColdKeeper never sees it.

— COLDKEEPER PRO — ONE-TIME UNLOCK
For €7.99 / $7.99 (one-time, never expires) you unlock:
• Unlimited history
• All advanced protocols + custom protocol builder
• Apple Health integration
• iCloud sync across all your Apple devices
• Home Screen widgets (streak + last session)
• Detailed weekly and monthly stats

— PRIVACY BY DESIGN —
No analytics. No ads. No tracking SDKs. No accounts. Your sessions live on your iPhone (and your private iCloud, if you opt in). The developer cannot see them. Read the full privacy policy at maximesaltet.com/coldkeeper/privacy.

— BUILT NATIVELY FOR iOS —
SwiftUI. SwiftData with CloudKit. StoreKit 2. Core Haptics. HealthKit. Localized in English and French. Light + dark mode. Dynamic Type ready. Built and maintained by an indie developer who actually answers your emails.

— DISCLAIMER —
ColdKeeper is a wellness and lifestyle app, not a medical device. Cold exposure can be dangerous. Consult a physician before starting, especially if you have cardiovascular conditions. Never plunge in open water alone. The app does not diagnose, treat, or prevent any condition.

Stay frosty.
