Help & FAQ

No — and Sothis tells you that inside the app too. Astrology, numerology and biorhythms are unproven systems. What Sothis does is apply them consistently, then let you measure the result on your own life. The diary turns "do you believe this?" into "does it actually work for you?"

Your birth date is required; birth time, name and partner details are optional. Your birth data and diary entries stay on your phone — Sothis doesn't ask for your location, your contacts or your social accounts. Full detail in our privacy policy.

No ads on either — ever. Free Light keeps the daily verdict, your three biorhythms, a 7-day calendar and the diary, forever. Premium adds the 90-day calendar map, multiple profiles, smart notifications and PDF export. You start with the full app free for 14 days.

Subscriptions are managed by Google Play (or the App Store). Open your device's store app → your account → Subscriptions → Sothis → Cancel. Your access continues until the end of the current billing period.

That's exactly what the diary is for. Use Sothis for two or three months, log how each day actually went, and read your personal hit-rate. If it's high, the system is doing something for you. If it isn't, you'll know — and we'd rather you know.
