Is Crystal of the Day free to use?

Yes, Crystal of the Day is completely free to use with no account, subscription, or hidden fees required. Astralium is committed to making spiritual tools accessible to everyone. You can use Crystal of the Day as many times as you like, any day of the week. The only thing you need is a modern browser. All 255+ tools on Astralium follow the same principle: free, private, and always available.

How does Crystal of the Day work?

Crystal of the Day runs entirely in your browser using algorithms built on established spiritual traditions — including the Rider-Waite-Smith tarot system, Pythagorean numerology, and Western tropical astrology. When you interact with the tool, a seeded random process combines the current moment with your input to generate a result. No data is sent to any server and nothing is stored. All calculations happen locally on your device, so your readings remain completely private. You can refresh or repeat a session at any time without losing your privacy.

Can I use Crystal of the Day on my phone?

Yes, Crystal of the Day works on smartphones, tablets, and desktop computers. The interface is fully responsive and adapts to any screen size. On mobile, touch gestures are supported for an intuitive experience. You can also install Astralium as a Progressive Web App (PWA) on your home screen for quick access to Crystal of the Day and all other tools — no app store required. The PWA works offline for many features, so you can consult Crystal of the Day even without an internet connection.

How accurate is Crystal of the Day?

Crystal of the Day draws on centuries of accumulated wisdom from spiritual traditions — not on scientific prediction algorithms. The Rider-Waite-Smith tarot tradition, Pythagorean numerology, and Western astrology are symbolic frameworks designed to support self-reflection, not to forecast external events with certainty. Results from Crystal of the Day are best understood as mirrors for your own inner state, inviting you to explore patterns, possibilities, and meanings that resonate with your current situation. Many users find them valuable for clarity and perspective, while maintaining personal discernment about any guidance they receive.

Is my data private when I use Crystal of the Day?

Absolutely. Crystal of the Day processes everything in your browser. No personal data — not your birth date, your questions, or your results — is ever sent to a server. There is no account system, no tracking of individual readings, and no way for anyone (including Astralium) to see what you do with Crystal of the Day. Your spiritual practice remains yours alone.
