1. Who We Are
Universalvani ("we," "us," "our") publishes digital books at universalvani.org. This policy explains how we handle personal information for visitors and customers of this site.
2. Information We Collect
We collect only what's needed to deliver your book and support you afterward:
- Checkout details: name, email address, and mobile number, entered by you at checkout.
- Payment information: processed directly by our payment partners (Razorpay and/or Cashfree) — we do not receive or store your card, UPI, or bank credentials ourselves.
- Order records: order ID, payment ID, product purchased, and timestamp, used to verify your purchase and issue your download link.
- Newsletter signups: your email address, if you choose to subscribe, stored until you unsubscribe.
- Contact form submissions: whatever you include when writing to us.
- Basic technical data: standard server logs (IP address, browser type, pages visited) collected by our hosting provider (Vercel) for security and rate-limiting purposes.
- Kasturi assistant: the chosen language, whether voice or text was used, page path and question are sent to our assistant endpoint. When local rules cannot confidently understand an eligible question, a redacted version may be processed by Google Cloud Vertex AI only to classify its meaning; the provider does not write Kasturi's visitor-facing answer. Hindi, Marathi and Tamil voice input is sent securely through Universalvani to Google Cloud Speech-to-Text to create the editable transcript; English voice input uses the browser's speech service under the browser provider's own practices. Universalvani does not retain voice audio unless a signed-in user ticks the separate, per-recording consent checkbox before speaking. When that consent is given, a copy of that one recording is kept in private storage for authorized human review to improve Kasturi's speech recognition, for no more than 90 days. The user may delete all retained recordings earlier from My Account. Safety-sensitive recordings are not retained. The matched help topic, response-routing method and a redacted version of the question and non-personalized answer may also be recorded for human quality review. If you are signed in, authorized Universalvani administrators may view your profile display name and verified account ID beside these diagnostic records so they can understand conversation context and investigate quality problems; guest turns are grouped only by a random conversation ID that expires when the browser tab closes. Secrets such as OTPs, passwords, PINs, card details and email addresses are masked before provider processing and storage. Personalized answer text is not stored in this diagnostic log. These records are reviewed to prepare and test improvements; they do not automatically train or change Kasturi.
- Optional Kasturi product research: signed-in users may voluntarily provide a self-declared gender identity and separate consent for product research. We do not infer gender from names, voices or conversations. This information is kept separately from the normal profile, can be withdrawn and cleared from the profile page at any time, does not affect access or answers, and is used only for authorized quality review and aggregated trends. Small demographic trend groups are suppressed to reduce re-identification risk.
3. How We Use Your Information
- To generate and deliver your personalized, expiring download link.
- To send a backup copy of your book to your email.
- To respond to support requests and refund claims.
- To send newsletter updates, only if you've opted in — you can unsubscribe at any time.
- To prevent abuse (e.g. rate-limiting download requests).
- To understand broad, consented patterns in Kasturi usage and improve answer quality through human review.
We do not sell your personal information to anyone, ever.
4. Third Parties We Use
- Razorpay / Cashfree — payment processing.
- Vercel — website hosting and serverless functions.
- Upstash — backend data storage (rate limiting, download tracking, newsletter list).
- Resend — transactional and support email delivery.
- Google Cloud Vertex AI — bounded meaning classification for eligible Kasturi questions that local rules cannot confidently resolve; only the redacted question, selected language and limited page context are sent.
- Google Cloud Speech-to-Text — optional Hindi, Marathi and Tamil voice transcription. Audio is processed to return the transcript. Universalvani retains a separate copy only when the signed-in user gives explicit per-recording consent as described above.
Each of these providers processes data only as needed to perform their function for us, under their own privacy and security practices.
5. Download Link Security
Your download link is personalized and time-limited (72 hours) and includes a light, traceable watermark identifying your order. This is meant to discourage casual sharing, not to track your reading activity.
6. Your Rights
You can ask us to access, correct, or delete the personal information we hold about you by emailing support@universalvani.org. We'll respond within a reasonable time, consistent with any recordkeeping we're required to retain for financial/tax purposes.
7. Data Retention
We retain order records as required for accounting, tax, and dispute-resolution purposes. Newsletter emails are retained until you unsubscribe. Contact form messages are retained as long as reasonably needed to resolve your inquiry. Redacted Kasturi diagnostic logs are retained for human review for no more than 90 days, then deleted or irreversibly anonymized. Individually consented Kasturi voice recordings are automatically deleted no later than 90 days after collection, and a signed-in user can delete all of their retained recordings earlier from My Account.
8. Children's Privacy
Our services are not directed at children under 13, and we do not knowingly collect personal information from them.
9. Changes to This Policy
We may update this policy as our practices evolve. Material changes will be reflected by updating the "Last updated" date above.
