Privacy Policy

StarSol is operated by Salzventure Technologies LLC. StarSol provides astronomy media, constellation learning, sky guidance, and subscription features for TV and web. This policy explains what we collect, why we collect it, how we use and share it, and how to contact us.

Information We Collect

• Account information such as email address, display name, authentication provider, and subscription plan.
• Device and pairing information needed to connect a TV app to your account.
• Approximate observing location if you grant location access or save a location, used for sky conditions, ISS pass planning, and aurora context.
• Precise latitude and longitude only if you grant browser or device location access. You can instead use a default or manually saved location.
• Usage information such as app screens, playback state, feature interactions, and error logs used to operate and improve the service.
• Limited billing metadata from Stripe for web purchases and Google Play subscription status for Google TV purchases. We do not receive or store raw payment-card numbers.
• Communications you send to us, including support requests, privacy requests, and subscription questions.

How We Use Information

• To provide account access, subscriptions, restore purchases, and TV pairing.
• To show location-aware astronomy guidance when you enable those features.
• To maintain security, debug failures, prevent abuse, and improve product quality.
• To send transactional messages such as account, password, billing, and service notices.
• To comply with legal, tax, accounting, payment-platform, and app-store obligations.

Location Data

Location is used only for astronomy features such as sky context, ISS pass planning, weather/cloud context, and aurora watch status. If you grant location access, your device or browser may provide precise latitude and longitude. We use that location to request astronomy, weather, and map context and to save your chosen observing location if you ask us to. You can deny or revoke location permission in your browser or device settings; StarSol will use a default or saved location until you change it.

Payments

Web payments are processed by Stripe. Google TV subscriptions are processed by Google Play Billing. Each payment provider handles payment data under its own terms and privacy policy. StarSol receives only the information needed to verify entitlement, manage access, troubleshoot billing, and maintain required records. Deleting your StarSol account does not automatically cancel a subscription managed by Google Play or another app store; you must cancel those subscriptions through the store account where you purchased them.

Sharing

We do not sell personal information or share it for cross-context behavioral advertising. We share information with service providers that help operate StarSol, including hosting, email, authentication, analytics, billing, and astronomy/weather data services. We may disclose information if required by law or to protect users, StarSol, or the public.

Current service providers and data flows include hosting and database providers for account operation, Google and Apple for optional sign-in, Cloudflare Turnstile for signup abuse prevention, Stripe for web payments, Google Play Billing for Google TV purchases, Resend for transactional email, Open-Meteo for weather context, OpenStreetMap/Nominatim for optional reverse geocoding, WhereTheISS.at for ISS position context, and NASA/ESA/STScI/ESO/NOIRLab media sources or CDNs for astronomy imagery and video. Some third-party media, font, or data requests may receive your IP address and user-agent as part of normal internet delivery.

Retention

We keep account and subscription records while your account is active and for as long afterward as reasonably needed for legal, security, accounting, tax, dispute, and operational purposes. Billing and transaction records may be retained for up to seven years where needed for accounting, tax, or payment-platform compliance. Diagnostic, security, and server logs are generally retained for a limited period, commonly 30 to 90 days, unless needed longer to investigate abuse, fraud, payment issues, or security events.

Your Choices

• You can cancel subscriptions through the platform where you subscribed. Google Play subscriptions must be cancelled through Google Play.
• You can disable location permission in your device or browser settings.
• You can request account deletion, data access, correction, or export through available in-app tools or by emailing hello@starsol.app.
• Depending on where you live, you may have additional rights to know, access, correct, delete, portability, restriction, objection, or appeal. We will honor legally required requests after verifying your identity.

Security

We use reasonable administrative, technical, and organizational safeguards designed to protect personal information. No internet service is completely secure, and we cannot guarantee that unauthorized access, loss, misuse, or interruption will never occur.

International Use

StarSol is operated from the United States. If you use the Service from outside the United States, your information may be processed in the United States or other countries where our service providers operate, subject to applicable law.

Children

StarSol is not directed to children under 13. We do not knowingly collect personal information from children under 13.

Service Providers and Sub-Processors

We share data with the following third-party service providers to operate StarSol. Each provider receives only the data necessary to perform their services and is bound by appropriate data protection obligations.

None of these providers receive your data for their own advertising purposes.
