Terms of Use
SIA NextGen Technologies Private Limited · CIN U62099UP2026PTC250866 · Effective 30 September 2026 · Contact: Arya Kartikey Tiwari, +91 9140817930 · support@siavigyan.com
1. Who we are
SIA Vigyan — the Android app (com.sia.engine) and siavigyan.com — is operated by SIA NextGen Technologies Private Limited (CIN U62099UP2026PTC250866), 448/185, Nagaria, Thakurganj, Lucknow – 226003, Uttar Pradesh, India (“SIA”, “we”). These Terms, the Privacy Notice and the Refund & Cancellation Policy are the whole agreement between us. Purchases inside the Android app are also subject to Google Play’s terms.
2. Acceptance
By creating an account, paying, or using the service you accept these Terms — an electronic contract under section 10A of the Information Technology Act, 2000. We record which version you accepted and when.
3. Who may use SIA
You must be 18 or older. A person under 18 may be read only through an adult’s account, and that adult is the party to these Terms. Give accurate details, keep your sign-in safe, and answer for what is done under your account. Enter another person’s birth details only with their authority — for anyone under 18, only as their parent or lawful guardian — and never another person’s details as your own.
4. What SIA is, and is not
SIA reports what classical Jyotiṣa texts say about a birth chart and cites the verse behind each statement. Answers are phrased by a third-party AI language model from facts SIA selects; no human astrologer writes them, and the model adds no fact or verse. An answer’s wording may be inaccurate; the verse cited under each statement is the authority, and you should not rely on an answer without it. Readings are indications from the texts, not predictions: SIA guarantees no outcome, event, date or result, and every decision you take is yours. SIA is not medical, psychological, legal or financial advice; it is not a medical device and does not diagnose, treat, cure or prevent any condition. Where a text prescribes an upāya (mantra, dāna, gemstone), SIA reports what the text says; that is not treatment, and SIA sells no remedy. Never stop or delay medical treatment because of a reading. Readings depend on the birth details you enter; a birth-time estimate from Lagna Śodhana is an estimate with a stated reliability, not a certified time.
5. The free account, plans and purchases
There is no trial. A free account asks for no payment method and has no time limit. What the free account keeps, and what each plan and each one-time item gives, is stated on the plans page of the website and on the purchase screen in the app, which form part of these Terms. Allowances are monthly and do not carry over. Additional questions may be bought by any account; they are used after the account’s own questions and are kept until used. A life graph that is paid for stays open for the life of the account: a topic’s detailed assessment opens that topic’s graph, the “unlock everything” item opens every graph and every topic’s assessment of the kuṇḍalī it was bought for, and a graph made under a running plan stays open after the plan. The kuṇḍalī document, the dhan yog, a milan and a lagna śodhana open no graph. A plan that is no longer offered for sale continues, with the allowances and the price it was taken at, for an account that holds it and renews it without a break, subject to clause 8. A first correction of a chart’s birth details is free; a later change of date, time or place counts as a new cast. An unpaid one-time item expires after 7 days without charge.
6. Prices, renewal and cancellation
Prices are in Indian Rupees and include all applicable taxes; nothing is added at payment and no fee is charged for any payment method or for autopay. SIA is not registered under GST at present; if that changes, prices stay tax-inclusive. Website payments are processed by Razorpay Payments Private Limited; app purchases by Google Play, at the prices Google Play shows. Monthly plans renew automatically until you cancel; your bank or UPI app notifies you before each debit. Cancel any time — website: Settings → Plan → Cancel; app: Google Play → Payments & subscriptions → Subscriptions → SIA Vigyan → Cancel. Cancelling stops the next charge and keeps the period already paid for. A yearly website plan is a single payment with no auto-debit; a yearly app plan renews each year until cancelled in Google Play. One plan runs at a time; an upgrade takes effect at once with the unused days credited, a downgrade starts when the current period ends. A price change is announced at least 30 days before it applies to your next renewal, and you may cancel before it; a period already paid for is never repriced.
7. Refunds
The Refund & Cancellation Policy governs. In short: a period that has begun and a delivered item are not refunded on a change of mind; a charge made in error, a purchase not delivered, service that did not work as described, an item cancelled before it is built, and the unused part of a period when we close an account without cause are refunded in full to the original payment method. Nothing limits your rights under the Consumer Protection Act, 2019.
8. Changes to the service
We may change features, allowances, texts and readings. A change that reduces what a paid plan gives applies only from your next renewal, with at least 15 days’ notice, and you may cancel before it.
9. Promotions and the Founding member badge
A promotional rate states its seat limit and closing date; the seat count shown is the server’s count of confirmed payments. It applies to one account, once, on the plan and cycle it was taken, while the subscription stays continuous, and the regular price that follows is shown before you pay. The Founding member badge goes to the first 100 accounts to pay for any plan, or those paying before 1 October 2026 (IST), in order of confirmed payment; it changes no price and is never given for a complimentary or trial plan. A price shown beside a struck-through list price and without a closing date is the price in force for a new purchase, not a time-limited offer: the list price is the price that plan was last sold at, and the price in force may change for new purchases at any time and for a running subscription only as clause 6 says.
10. Acceptable use
No attempts to breach, overload, probe, scrape, crawl, bulk-download or reverse-engineer the service or derive its rules, prompts or software from its outputs; no circumvention of a technical measure; no automated or bulk querying; no resale or republication of readings, documents or the corpus; no use of SIA’s outputs to train or evaluate a machine-learning model; no abuse of our staff. Professional and Professional MAX plans include consent to use readings in your own consultations with your own clients, with attribution to SIA; no other resale is permitted without our written consent.
11. Intellectual property
The classical verses are in the public domain and SIA claims nothing in them. Everything SIA made — the software, the engine, its rule base, its glosses, the computed charts, the readings and documents, the designs, and the marks “SIA” and “SIA Vigyan” — is owned by or licensed to SIA NextGen Technologies Private Limited. You receive a personal, non-transferable licence to view, keep, print and share your readings for personal use (and client use under section 10). You keep your rights in what you enter and grant us a licence to use it to provide, secure and improve the service, as the Privacy Notice describes. If you believe content on SIA infringes your rights, write to support@siavigyan.com; disputed matter is removed on notice while we look into it.
12. Suspension and termination
You may delete your account at any time. We may suspend or close an account only for fraud or a payment reversed without cause, unlawful use, another person’s details entered without authority, a breach of section 10, abuse of our staff, or where the law requires it. If we close an account for any other reason, or withdraw a paid plan, we refund the unused part of the current paid period.
13. Liability
Nothing in these Terms excludes or limits any liability that cannot be excluded or limited under Indian law, including your rights under the Consumer Protection Act, 2019, or our liability for fraud or wilful misconduct. Subject to that, we are not liable for decisions you take or outcomes you attribute to a reading, for any indirect, consequential or special loss, or for the acts of Google Play, Razorpay, your bank, your network or your device; and our total liability for all claims is limited to the amount you paid us in the 12 months before the claim arose. The service is provided as it stands, without a promise of uninterrupted availability.
14. Your responsibility to us
You will make good any loss we suffer because you used the service unlawfully, entered another person’s data without authority, submitted content that infringes someone’s rights, or breached section 10. This does not apply to ordinary use.
15. Changes to these Terms
We may change these Terms for legal, security or product reasons, with at least 15 days’ notice of a material change in the app or by email. A change that reduces what you have already paid for applies only from your next renewal, and you may cancel before it.
