Terms of use

By using Sidellia you accept these terms. If you do not accept them, do not use the service.

Sidellia is a free natal-chart computation service powered by Swiss Ephemeris plus editorial astrological interpretation. The service is provided as is, without uptime guarantees.

We reserve the right to change, suspend, or close features without prior notice.

You may use Sidellia for personal, educational, or outreach purposes. You may share your chart and the AI prompt freely.

You may not: (a) automate mass requests that degrade performance; (b) attempt to access other users' data; (c) resell the service without authorization; (d) use the content to deceive or impersonate.

The code, design, copy, and computation engine are the property of the Sidellia team. The natal chart you generate is your personal data and yours to use as you like.

Editorial interpretations (catalog, profiles, glossary, celebrity readings) are protected by copyright; you may cite them with attribution but you may not copy them wholesale without permission.

Astrology is not a substitute for medical, legal, financial, or psychological advice. Sidellia is educational entertainment, not professional counsel. Do not make important decisions based solely on your chart.

We do our best to keep computations accurate (we use Swiss Ephemeris, the professional reference), but we do not warrant absolute accuracy and we accept no liability for decisions you make based on site content.

These terms are governed by Spanish and EU law (GDPR). For any dispute arising from use of the service, the parties submit to the courts of the consumer's domicile, in accordance with applicable consumer-protection law.
