About Numology
Free, transparent numerology calculators — built to show you the math, not just the result.
Why we built this
Most numerology websites give you a number without explaining how they got there. Numology was built to fix that. Every calculator shows the full step-by-step reduction chain, documents which system it uses (Pythagorean or Chaldean), and explains why intermediate values like master numbers and karmic debt numbers matter. You can verify every result yourself.
Numerology is a rich interpretive tradition, not a predictive science. We approach it as a tool for self-reflection — a structured way to look at the patterns in your name and birth date that many people find meaningful. We don't claim numerology predicts your future or makes decisions for you.
For the full calculation details, see the methodology page.

Data you enter into calculators
All calculations happen entirely in your browser. Your birth date, name, and any other
inputs are never transmitted to our servers. If you enable "Save my details on this
device," your profile is stored in your browser's localStorage only — no
server receives it.
Analytics
We use Google Analytics 4 to understand aggregate site usage (page views, device types, countries). GA4 only runs if you accept analytics cookies via the consent banner. We do not use advertising cookies, remarketing, or any third-party trackers beyond GA4.
Advertising
This site does not currently display advertisements. We plan to add Google AdSense in the future to support the cost of running the site. When we do, this policy will be updated and the consent banner will reflect the additional data use before any advertising is activated.
Cookies
We use one first-party cookie to store your consent choice. GA4 sets cookies only after you grant consent. You can withdraw consent at any time via the cookie banner (click "Cookie settings" in the footer) or by clearing your browser cookies.
Data retention
Saved profiles expire automatically after 30 days of inactivity (enforced in your browser). We hold no personal data on our servers. GA4 data is retained for 14 months per Google's default setting.

You can delete your locally saved profile at any time by clearing localStorage for numology.io in your browser settings. For questions about data handled by Google Analytics, refer to Google's Privacy Policy. To contact us about privacy, see the Contact section below.
