Stellr ("we", "us", "our") is the data controller responsible for your personal information collected through this Service. We are committed to protecting your privacy and handling your data in accordance with applicable data protection laws, including the General Data Protection Regulation (GDPR) where applicable.

Contact for all data and privacy matters: contact@stellr-app.com

We collect the following categories of personal data:

• Account data: Name and email address, collected when you create an account via Google Sign-In
• Birth data: Date, time, and place of birth - the core data used to generate your astrological chart
• Usage data: Pages visited, features used, session duration, and interaction patterns
• Device & technical data: IP address, browser type, operating system, and device identifiers
• Payment data: Billing information processed by Stripe. We do not store your payment card numbers
• AI chat content: Messages you send through the AI chat feature, processed to generate astrological responses

Under the GDPR, we process your personal data on the following legal bases:

• Contract performance (Art. 6(1)(b)): Birth data and account data are necessary to provide the Service you have requested
• Legitimate interests (Art. 6(1)(f)): Usage analytics and error monitoring to operate and improve the Service, where our interests do not override your fundamental rights
• Legal obligation (Art. 6(1)(c)): Retention of financial records and compliance with applicable law
• Consent (Art. 6(1)(a)): Marketing communications, where you have explicitly opted in

Where we rely on legitimate interests, you may object to that processing at any time by contacting contact@stellr-app.com.

We use your personal data to:

• Generate and display your Vedic birth chart, planetary positions, and astrological interpretations
• Power AI-assisted readings and the astrological chat feature
• Process payments and manage your subscription
• Send transactional communications (account notifications, billing receipts)
• Respond to your support requests and enquiries
• Monitor application performance and diagnose errors
• Analyse usage patterns to improve and develop the Service
• Comply with applicable legal obligations

We do not use your birth data or astrological information for advertising and we do not sell it to third parties.

We do not sell your personal data. We share it only with the following third-party processors, each bound by data processing agreements:

• Stripe, Inc. (United States) - payment processing and subscription management. Stripe Privacy Policy
• Google LLC (United States) - account authentication via Google Sign-In and usage analytics via Google Analytics. Google Privacy Policy
• Anthropic PBC (United States) - AI language model for chart interpretations and chat. Birth data may be transmitted to generate personalised content. Anthropic Privacy Policy
• Sentry (United States) - error monitoring and diagnostics, which may include usage context. Sentry Privacy Policy
• PostHog (United States/EU, depending on project settings) - product analytics, session diagnostics, and conversion analysis used to improve the Service. PostHog Privacy Policy

We may also disclose your data if required by law, legal process, or governmental authority, or to protect the rights, property, or safety of Stellr, our users, or others.

Your personal data may be transferred to and processed in countries outside your country of residence, including the United States, where data protection standards may differ from those in your country.

Where we transfer personal data from the European Economic Area (EEA), United Kingdom, or Switzerland to countries not recognised as providing adequate protection, we ensure appropriate safeguards are in place - such as Standard Contractual Clauses (SCCs) approved by the European Commission, or equivalent mechanisms recognised under applicable law.

For more information about the safeguards applied to international transfers, contact contact@stellr-app.com.

We retain your personal data for as long as your account is active, plus a reasonable period to allow reactivation.

• Account and birth data: Retained while your account is active. Deleted within 30 days of account deletion.
• Payment records: Retained for 7 years to comply with financial and tax regulations.
• Usage and analytics data: Identifiable data retained for up to 24 months; then aggregated and anonymised.
• AI chat history: Retained for the duration of your account and deleted with it.
• Support communications: Retained for 3 years after resolution.

You may request early deletion of your personal data at any time - see Your Rights below.

We use cookies and similar tracking technologies for the following purposes:

• Essential cookies: Session management and authentication - required for the Service to function and cannot be disabled.
• Analytics cookies: Google Analytics (via Google Tag Manager) and PostHog - used to understand usage patterns and improve the Service. These may associate data with your IP address and account identifier when you are signed in.
• Error tracking: Sentry - captures diagnostic data when errors occur, which may include session context.
• Preference cookies: Language selection and user interface settings.

You can control non-essential cookies through your browser settings. Disabling analytics cookies does not affect core Service functionality; however, blocking essential cookies will prevent login and most features from working.

Depending on your location, you have the following rights regarding your personal data:

• Access: Request a copy of the personal data we hold about you
• Rectification: Request correction of inaccurate or incomplete data
• Erasure: Request deletion of your personal data (“right to be forgotten”), subject to legal retention requirements
• Restriction: Request that we limit processing of your data in certain circumstances
• Portability: Receive your data in a structured, commonly used, machine-readable format
• Object: Object to processing based on legitimate interests or for direct marketing purposes
• Withdraw consent: Where processing is based on consent, withdraw it at any time without affecting prior lawful processing
• Lodge a complaint: File a complaint with your local data protection authority (e.g., the ICO in the UK, or your national supervisory authority in the EU)

California (CCPA): California residents have the right to know what personal information we collect, to request deletion, and to opt out of the sale of personal information. We do not sell your personal information.

To exercise any of these rights, contact contact@stellr-app.com. We will respond within 30 days and may request identity verification before processing your request.

Stellr does not currently have a formally designated Data Protection Officer (DPO). Under GDPR Art. 37, a DPO is required where processing is carried out on a large scale involving special categories of data or systematic monitoring of individuals. As Stellr grows, we will review this obligation and appoint a DPO if required.

In the meantime, all data protection enquiries - including requests to exercise your rights, concerns about our processing activities, or questions about this Privacy Policy - should be directed to:

Data protection contact: contact@stellr-app.com

We will acknowledge all data protection enquiries within 5 business days.

The Service is not directed to children under the age of 13. We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has provided personal information to us without your consent, please contact contact@stellr-app.com immediately and we will delete the data as quickly as reasonably practicable.

Users between 13 and 18 should ensure a parent or guardian has reviewed and agreed to our Terms of Service before using the Service.

We may update this Privacy Policy from time to time to reflect changes in our practices, technology, or legal requirements. When we make changes, we will update the “Last updated” date at the top of this page.

For material changes that significantly affect how we handle your data, we will provide additional notice - such as an in-app notification or email to your registered address - with reasonable advance notice before the changes take effect.

Your continued use of the Service after the effective date constitutes acceptance of the updated Privacy Policy.
