Answers to everything you want to know

Birth Codex is a personal cosmic reading that unites 23 Western and Eastern wisdom traditions in a single tool — Human Design, astrology, numerology, Gene Keys, Vedic astrology, the Mayan calendar and more. Every calculation is astronomically precise (Swiss Ephemeris on NASA JPL data), and the interpretations are written individually for you. No other tool combines this depth in one reading.

Those tools are each strong in one tradition: CoStar in Western astrology for mobile, Jovian Archive in Human Design, Astro.com in deep astrological calculation. Birth Codex is broader — you get all 23 cosmic systems in one reading: astrology + Human Design + numerology + Vedic + Mayan + tarot + Gene Keys + 12 more. Astronomically precise via Swiss Ephemeris (the same NASA JPL source as Astro.com), but as one connected profile instead of 23 separate tools. Plus: no ads, no subscription, no re-billing — a one-time payment instead of a monthly trap. You'll find the direct comparison on the comparison page — 7 concrete dimensions.

Sonic Blue and Yara Joy — we are the founders of the DNX movement, the first and largest community for location-independent entrepreneurs, with festivals in Berlin, Bangkok and Lisbon and coliving camps in more than 10 countries worldwide. Since 2014 we have personally explored personal development, spirituality, astrology and Human Design. You can find more details on our About page.

Over the years we did hundreds of readings across all kinds of tools — none of them united Human Design, astrology, Vedic knowledge, numerology, Mayan, Gene Keys and every other system in one personal reading. So we built it ourselves. Birth Codex is the tool we wished we'd had — back when we started exploring our own cosmic code twelve years ago.

No, Birth Codex is a pure web application — it works instantly in your browser on any device (mobile, desktop, tablet). No app install, no sign-up, no cookie consent required. You enter your birth data, and after a short wait your reading is ready.

All astronomical positions are calculated with Swiss Ephemeris — the same library used by professional astrologers, observatories and NASA. It is based on NASA's JPL ephemerides (DE431) and is accurate to the arc-second across several millennia. Numerology, the Mayan Tzolk'in, the Nakshatras and every other system follow the classic, deterministic rules of their tradition. The numbers are facts.

Swiss Ephemeris is an open-source library for calculating astronomical positions — the gold standard for astrological software since the 1990s. It was developed by Astrodienst, a Swiss company. The library uses JPL ephemerides (NASA Jet Propulsion Laboratory) as its data source — exactly the data used for spaceflight calculations and observatories.

Your first name, date of birth, the most precise birth time you have, and your place of birth. The more precise the time, the more accurate your ascendant and your Human Design profile — the profile lines sometimes change every 15 minutes. If you don't know your exact birth time, you can still create a reading, but the profile and ascendant may be less reliable.

Check your birth certificate, ask your parents, or contact the registry office of your place of birth — they almost always have the time in the birth register. If you truly can't find it: you can still use Birth Codex. Astrology, numerology, your Human Design type and authority, Gene Keys, Vedic astrology and most other systems work even without an exact time — only the ascendant, HD profile and some Moon-related values become less precise.

Yes — the JPL ephemerides cover roughly 13,000 BCE to 17,000 CE. For any birth date in the last few millennia the calculation is possible with arc-second precision. Even for birth dates in the 1920s, 1930s or earlier, Birth Codex delivers the same accuracy as for modern dates.

Your Human Design chart (type, profile, authority, strategy, complete bodygraph), your numerology (life path number, expression number, soul urge number), your astrology basics (Sun, Moon, ascendant plus element, modality and ruler), your cosmic power places on the world map and your personal soul profile as an aggregate interpretation — all with individual interpretation, not just raw data. With most tools that only starts in the paid version.

All 23 cosmic systems with a detailed individual interpretation. Beyond the free teaser: Western and Vedic astrology, Gene Keys, dharmic destiny, the Mayan calendar, Chinese astrology, the Celtic tree calendar, tarot, transit analysis, progressions, soul archetype, spirit animal, I Ching, biorhythm, Arabic Lots, the Lilith cycle and your soul profile — plus the full HD depth (incarnation cross, all variables, channels, gates).

Unlike pure HD generators that show only type and profile, with Birth Codex you get the full HD depth: type, profile, authority, strategy and the complete bodygraph with all active channels and gates. Plus your incarnation cross, all defined centers with an individual explanation of what that energy means for you, your 4 variables (digestion, environment, perspective, motivation) with their respective color meanings, plus your signature and your not-self theme. That's HD depth you'd otherwise only find in paid 1:1 sessions.

Completely individual. Your reading is written for you in real time the moment you click 'Create reading', based on your exact calculation data. No copy-paste from a database, no pre-made paragraphs. Even if two people are born on the same day, their readings differ — because the time and place of birth shift the astrological houses, the ascendant and the HD profile.

After you click 'Create reading' it typically takes 15 to 25 seconds for your free teaser to appear. While you wait you'll see a loading screen with rotating explanations of what's happening. The calculations themselves (Swiss Ephemeris, numerology, etc.) finish in milliseconds — the time goes into the individual interpretation that Birth Codex writes for you live.

A one-time payment after your free teaser — no subscription, no hidden costs, no automatic renewal. You'll see the exact price right after the teaser on the reading page, where you can also redeem any promo codes.

Payment runs through Stripe — we accept credit cards (Visa, Mastercard, American Express), Apple Pay, Google Pay, Klarna and SEPA direct debit. Which methods are shown depends on your location — Stripe automatically selects the ones available to you.

No. Birth Codex is a pure one-time payment. There is no subscription, no automatic renewal, no hidden follow-up costs. What you buy once is yours permanently.

For digital products, the following applies under German law (§356(5) BGB): if you expressly agree at checkout that the reading is delivered immediately, you waive the 14-day right of withdrawal. We mark this clearly at checkout with a separate checkbox. Without that consent we cannot deliver the reading immediately, because it is created before the withdrawal period ends.

Yes. Right after payment, Stripe automatically sends you an invoice to your email address. The invoice contains all legally required details (buyer data, seller GML, VAT note where relevant) and can be used directly for accounting or tax purposes.

Permanently. After purchase you receive an email with a permanent link to your reading. This link works indefinitely — you can reopen your reading in a year, in ten years, or any time in between.

Yes. Open your reading in the browser and print it with the browser's print function (Ctrl+P or Cmd+P). The layout is print-friendly — reading sections break cleanly, with no ads and no navigation. If you want a PDF, choose 'Save as PDF' in the print dialog.

Technically yes — you can pass on your permanent reading link. However, your reading is very personal (birth data, an individual interpretation of your cosmic profile), so we recommend caution when sharing. Anyone with the link can see the reading.

Your birth data is processed to create your reading and kept internally for anonymized statistics (no full name, no full IP address, no email link in the statistics database). Full details are in our privacy policy.

Yes. We host in the EU (Vercel + Cloudflare EU regions), use GDPR-compliant providers (Stripe, Brevo) and have a complete privacy policy with a legal basis for every processing activity. You have the right to access, correct and delete your data at any time.

No. We do not sell data and do not pass any data to third parties for marketing purposes. The only external providers are: Stripe (payment processing), Brevo (transactional emails), Vercel (hosting), Cloudflare (DNS + CDN), Upstash (database) — all GDPR-compliant and only for technical operation.

A short email to [email protected] requesting deletion is enough. We delete your entry in our internal statistics database, your Telegram history and any other records linked to you without delay (typically within 24–48 hours).

Most tools only show you a table of raw data for free — and hide the personal interpretation behind a paywall. With Birth Codex you get an individually written reading with real insights for free, not just numbers. Every single reading is calculated and written for you in real time. The full reading unites 23 Western and Eastern traditions at a depth you won't find anywhere else.

The calculations are mathematically unambiguous. Swiss Ephemeris is the same library used by professional astronomers and NASA — planetary positions accurate to the arc-second. Numerology, the Mayan Tzolk'in, the Nakshatras and all 23 cosmic systems also follow clear, deterministic rules. The numbers are facts. What you take from them for your life is your interpretation. Birth Codex doesn't give you generic fortune-cookie lines, but a reading tailored individually to your moment of birth.

The calculations are mathematically unambiguous — that's verifiable astronomy and numerology. What isn't scientifically provable: the causal effect of these constellations on your life. Spiritual systems like astrology, Human Design or numerology are systems of symbol and meaning — they don't act causally like laws of nature, but as psychological resonance spaces that can help you understand yourself and your life better. Birth Codex delivers the exact data — what you make of it is up to you.
