Terms of Service

Agreement#

These Terms of Service ("Terms") govern your use of the Stellara app, published by Walker Interactive LLC ("we", "us", "our"). By using Stellara, you agree to these Terms. If you do not agree, do not use the app.

Eligibility#

You must be at least 13 years old to use Stellara. If you are under 18, you may use Stellara only with the involvement and consent of a parent or guardian. Stellara shows advertising and includes live user chat, and it is not designed for children.

Acceptable use#

You agree to use Stellara only for lawful purposes. In chat and other community features, you agree not to harass, threaten, or abuse other users; post illegal, hateful, or sexually explicit content; impersonate others; or spam.

You agree not to scrape, crawl, reverse-engineer, or use automated means to extract data from the app or its backend services beyond normal use, and not to attempt to circumvent rate limits or access controls.

Advertising#

Stellara is free to use and is supported by advertising. You agree not to block, interfere with, obscure, or circumvent the delivery of ads, and not to click on ads fraudulently or automatically. Purchasing Stellara Pro removes all ads.

Purchases & refunds#

Stellara Pro unlocks ad-free use of the app. It is offered as a Monthly or Annual auto-renewing subscription, or as a one-time Lifetime purchase; exact current prices are shown to you at the point of sale before you buy, and may change over time.

The Annual subscription may include a 7-day free trial. If you do not cancel before the trial ends, it converts automatically into a paid Annual subscription and you are charged the price shown at purchase.

All purchases are billed through Google Play, under your Google account and Google Play's terms. A Monthly or Annual subscription renews automatically at the interval and price shown at purchase until you cancel it in Google Play (Play Store app → Payments & subscriptions); cancelling stops future renewals and does not retroactively refund the current period. A Lifetime purchase is one-time and does not renew or expire.

Refunds are handled by Google Play under its refund policy — we cannot issue refunds directly for Google Play purchases. If your purchase does not unlock, use "Restore purchases" in Settings, which restores any Pro entitlement attached to the same Google account. If that does not resolve it, contact us at walkerinteractivellc@gmail.com.

We may change what Stellara Pro includes or what it costs. Changes will not retroactively remove a benefit you have already paid for in a one-time purchase or in the current subscription period.

Your content#

You keep ownership of the messages, display handle, and feedback you post or send in Stellara. By posting, you grant us a non-exclusive, worldwide, royalty-free licence to store, display, and transmit that content within the app for the purpose of operating it. Chat messages are automatically deleted from our servers after 3 days.

You are responsible for what you post. We may remove content, reclaim a handle, or restrict or terminate access, at our discretion, for content or conduct that violates these Terms — including through automated filtering.

To report abusive content or a user, email walkerinteractivellc@gmail.com with enough detail to identify the message. We review reports and act on them.

Intellectual property#

Stellara's app design, code, and original content are owned by Walker Interactive LLC or its licensors and protected by intellectual property laws. You may not copy, redistribute, or create derivative works from the app itself without our permission.

Third-party content — including NASA and JPL imagery and data, NOAA space-weather data, Wikipedia excerpts, SIMBAD/CDS catalog data, Launch Library data, Celestrak orbital elements, and Solar System Scope textures — remains the property of its respective owners and is used under the licenses described in Credits & Licenses. Their use in Stellara is not an endorsement of Stellara by them.

Third-party services & links#

Stellara embeds and links to content we do not control, including YouTube webcasts and observatory and agency websites. We are not responsible for that content or for those services, and your use of them is governed by their own terms and privacy policies.

Disclaimer of warranties#

Stellara aggregates astronomical data from third-party sources and performs on-device astronomical calculations. This data and these calculations are provided "as is" for informational and entertainment purposes only, without warranty of any kind, express or implied, including accuracy, completeness, or fitness for a particular purpose.

Do not rely on Stellara for safety-critical, navigational, or scientific decision-making. Launch times, event timing, satellite passes, and celestial positions may be approximate, delayed, or incorrect. The app may be unavailable, and third-party data sources may fail or change without notice.

Limitation of liability#

To the maximum extent permitted by law, Walker Interactive LLC shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of data, arising out of or related to your use of Stellara, even if advised of the possibility of such damages. Our total liability for any claim relating to the app shall not exceed the amount you paid us, if any, in the twelve months preceding the claim.

Termination#

You may stop using Stellara at any time, and you may delete your account and its data from Settings → Account. We may suspend or terminate your access if you materially breach these Terms or use the app unlawfully. The Intellectual property, Disclaimer of warranties, Limitation of liability, and Governing law sections survive termination.

Distribution through Google Play#

Stellara is distributed through Google Play, and Google Play's terms of service also apply to your download and use of it. Google is not a party to these Terms, is not responsible for Stellara, and provides no warranty for it.

Governing law#

These Terms are governed by the laws of the State of Utah, United States, without regard to its conflict-of-law principles. You agree that any dispute arising from these Terms or from your use of Stellara will be brought exclusively in the state or federal courts located in the State of Utah, and you consent to the personal jurisdiction of those courts.

Changes to these terms#

We may update these Terms from time to time to reflect changes to the app or to applicable law. Material changes will be reflected by updating the date at the top of this document. Continued use of Stellara after changes take effect constitutes acceptance of the revised Terms.
