Can I switch tiers any time?

Yes. Upgrades take effect immediately and are prorated; downgrades take effect at the next billing cycle so you keep your current quota until then.

Is GST charged on top of these prices?

Yes — Indian customers pay GST per state. CGST + SGST for Maharashtra-billed accounts; IGST for inter-state. International customers see USD prices without GST.

What if I exceed my quota?

At 80% you'll see a banner in the dashboard. At 100% calls return 429 until you upgrade or the next billing cycle starts. No surprise overage charges.

Do you offer annual discounts?

Not yet — annual billing is on the roadmap. Pro and Custom contracts can be negotiated annually via /contact.

Within 14 days of purchase, refundable in full if usage is below 10% of the plan's monthly quota. See /refund-policy for the full terms.

Questions

Things people ask before they integrate.

How accurate are the planetary positions?+

Sub-arcminute. We use Swiss Ephemeris with the Lahiri ayanamsa as default, and our published charts match AstroSage and DrikPanchang within ±0.05° on every reference fixture. Determinism is guaranteed: same input + engine version = byte-identical output.

What ayanamsa and house system do you use?+

Lahiri ayanamsa and whole-sign houses by default — the most-cited Vedic convention in India. KP-Newcomb + Placidus support is on the roadmap (Phase 11). The output meta block always names the convention used so consumers can disambiguate.

Where is birth data stored?+

It isn't. By default we don't persist birth inputs beyond the request lifecycle — only request hashes for debugging. Reports the user explicitly saves are stored for 30 days, then purged. DPDP-aligned and GDPR-aligned.

Can I run this on-prem / self-host?+

Not yet. The engine is a workspace package today; we may publish it as a standalone binary in the future. Talk to us on the Custom plan if your compliance posture requires on-prem.

Do you support refunds?+

Yes — see the refund policy. Short version: pro-rata refund within 14 days of paid subscription if you haven't exceeded the free-tier quota.

Why "BPHS canonical" — and what does that mean for compatibility?+

Brihat Parashara Hora Shastra is the source text most modern Vedic software pins to. Our compatibility scoring follows BPHS verses 5–7 for the Ashtakoot tables and applies the canonical half-marks cancellation rule. Every koot exposes both the raw initial_score and the post-cancellation score so callers can render either.
