The data controller is Sigvanta LLC, Wyoming, USA. For privacy matters contact info@sigastra.com.

What we collect

Birth data you enter — date, time and place of birth — used solely to compute your astrological chart. This is the core of the service.

Account data — your email address, and (if you sign in with Google) your Google account identifier and basic profile.

Payment data — handled by Stripe; we store only a Stripe customer/subscription identifier and purchase records. We never see or store your full card number.

Usage data — basic logs needed to run and secure the service, and, only with your consent, privacy-friendly analytics.

How we use it

To calculate your chart from astronomical data and generate your readings (see AI processing below).

To create and secure your account, send transactional email (verification, password reset) and process payments.

To understand and improve the product in aggregate, where you have consented to analytics.

AI processing

Your readings are generated by large language models operated by Anthropic. We send the computed, non-identifying chart data (planetary positions, not your name or email) to Anthropic to produce the text. We do not send your email or payment details to the model.

Processors we use

Anthropic (AI text generation), Stripe (payments), Google (optional sign-in), Postmark (transactional email), Microsoft Clarity (analytics), Cloudflare (DNS), and our hosting provider. Each processes data only on our instructions and under its own security and privacy commitments.

Your rights (GDPR & similar)

If you are in the EEA/UK you have the right to access, rectify, erase, restrict and port your data, and to object to processing. You may withdraw consent at any time. To exercise any right, email info@sigastra.com. You also have the right to lodge a complaint with your local supervisory authority.

Retention

We keep your chart and account data while your account is active. If you delete your account or ask us to erase your data, we remove it (subject to limited legal/accounting retention for payment records).

Delete account

You can delete your Sigastra account and its data yourself, at any time, in the Sigastra app (Android) or on the website.

In the app: open the Profile tab, scroll to the "Delete account" card at the bottom, type DELETE and tap "Delete account". On the website: sign in, open sigastra.com/account, scroll to "Delete account", type DELETE and confirm.

If you cannot sign in, email info@sigastra.com from the address on your account and ask us to delete it; we do so within 30 days. You can also ask us to delete only part of your data (for example your birth data or chat history) without closing the account.

Deleted immediately and permanently: your account and email, your birth data and natal chart, all readings and forecasts, tarot draws, chat history with the AI astrologer, push-notification subscriptions and your marketing profile (also removed from our email provider).

Kept: payment records (amount, date, product) are retained only for as long as tax and accounting law requires, detached from your account. Aggregated, anonymous usage statistics are not deleted because they no longer identify you. An active Google Play or Stripe subscription is not cancelled by deleting the account; cancel it in Google Play or in your Stripe receipt first.
