Your chart is not a prediction.It's a decision lens.

The birth-chart engine names its authorities. Brihat Parashara Hora Shastra supplies the Yoga Karakas for each of the twelve rising signs and the five Panchamahapurusha Yogas. Kalyana Varma's Saravali supplies the Lunar and Solar Yogas, the Nabhasa chart-shape yogas and the Planetary Rays score. Bhrigu Sutras sits behind the planet-in-house table. Jyotisha-Siddhanta-Sara gives the Navamsa method and all twenty-seven Janma Nakshatra temperaments. S. Kannan's Fundamentals of Hindu Astrology gives Shad Bala, the dignity and friendship tables, the Bhinnashtakavarga contribution tables and the Gochara transits read from your natal Moon.

The numerology engines are kept separate by book rather than merged into one score. Advanced Vedic Numerology by Pankaj Chauhan supplies the Vedic Grid combinations and a numerology dasha timing layer. Dr. Oliver Tan's Power of Numbers contributes its own inverted-triangle chart and Root Number, a different construction from Mulank or the Lo Shu grid. Sepharial's grid and the Chaldean name numbers come from Rrachita Gupta's Life With Number Magick. The Chaldean letter table sits in its own file, because the name table used elsewhere is Pythagorean, not Chaldean.

Naming a source also means recording what was not taken from it. Of Daivajna Vallabha's fifteen chapters the Prashna feature implements six; the warfare, death-prediction and rainfall chapters are excluded by decision, not oversight. Saravali names thirty-two Nabhasa Yogas and all are built; where Saravali and BPHS word a shape differently, the engine follows BPHS and records Saravali's reading beside the code. Bhrigu Sutras' own disease predictions and death-timing passages were dropped on the way into the planet-in-house table, and the code records that beside it.

The Vimshottari timeline is keyed to a single number: your Moon's sidereal longitude at birth. Which of the 27 nakshatras it falls in picks the first of nine planetary lords, and the fraction of that nakshatra already crossed is subtracted from that lord's period - so the first Mahadasha is partial, and every later date shifts with it. The nine fixed lengths total 120 years, so the sequence runs from birth to roughly 120. With no birth time on file, noon is assumed, and the chart is recomputed at both ends of the birth day to see whether both ends give the same running Mahadasha.

Below the Mahadasha the same arithmetic runs twice more. A parent period is split between the nine lords in the ratio of their own year-lengths, starting from the parent's own lord - one function applied at both levels, not two implementations to keep in step. The middle level is still wide: an Antardasha inside the nineteen-year Saturn Mahadasha runs a little over three years. The Pratyantardasha below it is weeks to months, which is the scale a real decision sits on. All nine Mahadashas are published with their Antardashas nested.

Transits are the second layer, and they move no dasha date. Gochara reads where all nine grahas are today, counted from your natal Moon's sign rather than the ascendant. Saturn's own positions are named separately: the twelfth, first and second from the Moon are Sade Sati's rising, peak and setting phases; the fourth is Ardha Ashtama Sani, the eighth Ashtama Sani.

Two calculations run over the same birth record and never touch each other. The astrology side reads the Vimshottari Mahadasha derived from your Moon's position at birth; the numerology side reads your Personal Year, derived from your birth day and month against the calendar year. A tone rule that already existed for each side sorts a period into a tone, and those tones are renamed, not recalculated, onto one three-word axis: expand, build, hold. Because both halves land on the same three words, agreement becomes a literal equality check between two separately computed values rather than a claim you have to take on faith.

The axis is ordered, so the gap between the two stances is a distance: nought, one or two. Nought is reported as agreement. A gap of one is reported as a partial split, naming which side read what, and the more cautious of the two stances is the one put forward to act on. A gap of two is reported as a contradiction, in those words, with the suggestion that the year be treated as one to test small in rather than commit large. Neither reading is averaged into a middle answer; both stay on the page with their own stance.

No confidence percentage is attached to the verdict. What the page reports instead is how far the answer leans on information you did not give: with no birth time, the chart is recomputed at 00:00 and at 23:59 and the page states whether the ruling Mahadasha actually changes across that day, naming both candidate rulers when it does and saying so plainly when it does not. The separate track-record engine keeps to the same rule: three feedback measures held apart, never averaged into one score, with nothing quoted until at least five entries sit behind it.

The public calculators and the Convergence page run on unauthenticated routes, and their handlers persist nothing - no document is created and no counter on any model is incremented, so an anonymous visitor leaves no trace in the database. You can type a birth date, read the whole result rather than a teaser, and close the tab. The birth-place field is the one exception, and it is not a single request. From the second character you type, and until you pick a suggestion, that text goes to our own server to look up matching places; unless the bundled city list alone fills the suggestions, our server forwards it to Open-Meteo. A wrong latitude would quietly corrupt the ascendant and every house built on it, which is why the lookup exists.

An account stores more, and the privacy policy inventories it field by field rather than by category: sixteen fields you give us, thirteen derived values, and eight things collected automatically. The account record itself holds your name, email, your language and your goal, and a birth record - the date and time exactly as you typed them, whether a time was given at all, the place label, latitude, longitude, timezone offset, and the UTC instant derived from those.

Deletion is a real route, not an email address. Settings, under Data & privacy, asks you to confirm and then calls DELETE /auth/account. That handler walks one declared list of ten collections - profiles, chat, life events, practice logs, Prashna questions, share links, composed messages, delivery settings, WhatsApp consent and insight reactions - and removes the account row last, so a failure part-way through leaves an account that can retry rather than rows nobody can find. The list is declared rather than hand-written because three collections were once missed; an API test writes a real row into each of those three and fails if any of them is still there afterwards.

The clearest fit is someone with a specific decision in front of them - a launch, a resignation, a proposal - who wants a second read before committing. Ask, and you get YES, WAIT or NO with a confidence figure built from exactly two terms: how your current Mahadasha reads for that kind of decision, worth up to sixty points, and the Shad Bala strength of the planet ruling the relevant house, worth up to forty. Both terms are named on screen. You can log the verdict, then record later what actually happened.

It also suits the reader who would rather check the work than take it. Chapter references are printed beside the readings and deliberately left in English in all three languages, because a translated book title finds no passage - "BPHS Ch.68, Sloka 1-6" is meant to be looked up.

It is a poor fit for three people. Anyone wanting a guaranteed outcome: asked to compare two options of the same kind, it refuses, because the same category means the same house, the same lord and the same figures, and a winner picked between them would be a coin toss with a chart drawn on it. Anyone wanting a remedy to buy: the gemstone and deity fields that once shipped were removed. Anyone wanting a diagnosis or an investment call: the body section names no condition, and money timing states in its own words that it is timing quality, not financial advice.
