## What is Sunmaxxing?

You were not built for indoor lighting. Sunmaxxing turns getting outside
into a streak you'll actually keep — it finds your best sun window every
day, pings you when it opens, and ranks you up as you show up.

HOW IT WORKS
• Your Daily Sun Window — we crunch local UV, clouds, temperature, and
  air quality to find the smartest time for you to step outside
• The Signal — a push notification the moment your window opens
• Session timer — 5 to 20 minutes, survives app restarts, live UV on
  screen
• Streaks with Protected Days — rain all day? Unsafe UV? Your streak is
  protected. We never push you outside in bad conditions.
• Seven ranks — from Basement Dweller to Certified Sunmaxxer. Streaks
  are the only way up.

BUILT-IN SUN SAFETY
Sunmaxxing is about consistency, not UV dosage. Protection reminders at
UV 3+, personal UV limits tuned to your skin's sensitivity, and no
streak pressure when conditions aren't safe. No medical claims, no
tanning promotion — just you, outside, at the right time.

Your location is used only while you use the app — never tracked in the
background. Manual city entry works too.

Sunmaxxing Pro is an auto-renewing subscription (weekly, monthly, or
yearly; the weekly plan starts with a 3-day free trial). Payment is
charged to your Apple Account; the subscription renews unless cancelled
at least 24 hours before the period ends. Manage or cancel in Settings.
