FAQ
Your questions, answered
Which skin types does it support?
Soluma supports 6 skin types — from fair and sensitive to deep skin tones. During onboarding, Vitamin D synthesis and burn risk thresholds are personally calibrated to your selected skin type.
How up-to-date is the UV data?
We use hourly UV forecast data from Open-Meteo. The app fetches the latest forecast for your location each time you open it, and data refreshes automatically during an active session.
How accurate is the Vitamin D tracking?
We use scientific models that combine skin type, UV index, season, and exposed body surface area. While not as precise as a blood test, it's accurate enough to meaningfully guide your daily habits.
How do you use my location data?
Location is used solely to fetch UV data and never leaves your device. It is never stored on any server or shared with third parties.
How much battery does it use?
It does not continuously monitor location in the background. Location is accessed briefly only when you open the app or start an active session, keeping battery usage to a minimum.
Is the app free?
Yes, Soluma is free to download on the App Store. All core features — Sun Score, safe windows, Vitamin D and burn risk tracking — are available at no cost.
