Privacy Policy

Last updated: 19 April 2026

This policy explains what information we collect, why we collect it, and what rights you have over your data. It applies to numerastra.com and all associated services.

The short version

• Free calculations happen on your device — your name and DOB never leave your browser.
• For paid accounts, we store the bare minimum: mobile number, email (if provided), subscription status.
• We never sell your data or share it with advertisers.
• We use Razorpay and Stripe for payments — we never see or store your card details.
• You can delete your account and all associated data at any time.

What we collect

For free users

Nothing leaves your device. Numerology calculations happen entirely in your browser using JavaScript. We use Plausible Analytics for privacy-respecting site statistics — it does not use cookies, does not collect personal data, and does not track you across other websites. It only counts pageviews and approximate country (derived from IP, then discarded). This does not include your name, date of birth, or any input you make.

For registered users

• Mobile number — required for OTP login.
• Email address — optional, for receipts and support.
• Subscription status and billing history — required for access control.
• Saved profiles — the names and DOBs you add to your account (Pro tier). These are stored encrypted and never shared.
• AI conversation history — the questions you ask our AI and the responses, for quality and safety. We retain these for 90 days, then delete.

Payment data

All payment processing happens at Razorpay (India) or Stripe (international). We receive only the transaction ID and subscription status. We never see, store, or handle your card or UPI details.

How we use your data

• To authenticate you (OTP delivery).
• To provide the features you signed up for (reports, AI, saved profiles).
• To process payments and manage subscriptions.
• To send transactional emails (receipts, subscription renewals). You can opt out of marketing emails — we don't send any without your explicit permission.
• To improve our services through anonymised, aggregated analytics.

Data sharing

We do not sell your data. We do not share it with advertisers. We do share data with the following service providers strictly as needed to run the service:

• MSG91 / Twilio — to deliver OTP messages to your mobile number.
• Razorpay / Stripe — to process payments.
• Supabase — our database provider (Singapore datacenter).
• Anthropic (Claude API) — to power our AI numerology assistant. Only the questions you explicitly ask the AI are sent; your personal numerology data is never sent to third-party AI providers.
• Plausible Analytics — for privacy-respecting traffic statistics. No cookies, no cross-site tracking, no personal data.

All providers operate under strict data processing agreements and are GDPR and India DPDP Act 2023 compliant.

Your rights

You have the right to:

• Request a copy of all data we hold about you.
• Correct any inaccurate data.
• Delete your account and all associated data.
• Export your data in a machine-readable format.
• Withdraw consent for marketing communications at any time.

Email support@numerastra.com to exercise any of these rights. We respond within 30 days.

Data retention

We keep your data only as long as needed:

• Account data: until you delete your account or three years after your last login, whichever comes first.
• Payment records: seven years, as required by Indian tax law.
• AI conversation history: 90 days.
• Anonymised analytics: 24 months.

Security

Data is encrypted in transit (TLS 1.3) and at rest. Passwords are not used (we use OTP). Access to production systems requires two-factor authentication. We run regular security audits and follow OWASP Top 10 best practices.

Children

Numerastra is not intended for users under 13. We do not knowingly collect data from children. If you believe a child has given us information, email support@numerastra.com and we will delete it immediately.

Updates to this policy

We may update this policy to reflect changes in our practices or for legal, operational, or regulatory reasons. Significant changes will be announced via email to registered users at least 30 days before taking effect.
