This is proposed publication text. The effective date will be stated in the publication notice. Before publication, the publication page should identify the provider by its legal name and include other legally required disclosures. The contact email throughout is gaoxiangsoft@163.com.
1 Scope and acceptance
These Terms of Service apply to your acquisition and use of the SkyScapeKit macOS app, its updates, related documentation, and developer support. “We” and “us” mean the developer and provider of SkyScapeKit. Our contact email is gaoxiangsoft@163.com.
Read these terms and the Privacy Policy before use. By downloading, installing, or using the app, you accept the terms applicable to that version to the extent recognized by applicable law. Matters requiring separate express agreement require valid agreement separately. If you disagree, stop using the app and handle any existing purchase under applicable store rules and law.
The app mainly provides local panorama stitching, stacking, and RGB + Hα alignment. Features, formats, and system requirements depend on the actual information for your version. These terms do not promise features that have not been provided.
2 Eligibility and equipment
You must have the legal capacity needed to enter into and perform these terms. Minors must have guardian guidance or consent where required by applicable law. If using the app for an organization, you must have authority to do so.
You need to own or lawfully control a compatible Mac, an appropriate software environment, and sufficient storage, and comply with Apple’s device and usage rules. Processing speed, capacity, and results may vary with hardware, system, file formats, and source materials.
3 Software license
Subject to applicable terms and lawful acquisition of the app, we grant you a limited, nonexclusive license to install and use it on devices permitted by Apple’s applicable usage rules. You may not resell, rent, or transfer the license without authorization, except as permitted by applicable rules, Family Sharing, or law. Copyright and rights not expressly granted remain with the relevant rights holders.
You may process materials you have the right to process and use photography and results you lawfully own for personal or commercial creative work. These terms grant no additional rights in third-party software, data, trademarks, materials, or databases. Their independent licenses and restrictions remain applicable, and these terms do not represent that any unconfirmed third-party permission has been obtained.
To the extent restrictions are lawful, you may not copy or redistribute the app without authorization, circumvent effective technical protection measures, or reverse engineer, decompile, or disassemble proprietary portions. These terms do not improperly restrict interoperability, security research, or other activities allowed by applicable law, or activities expressly permitted by third-party open-source licenses.
4 Your content and rights
You retain your intellectual property and other rights in originals, projects, and lawfully created results. Using the app does not give us ownership of your photos, and we do not require a copyright transfer or license for public display, marketing, or model training. Whether results are protectable and who owns them remain subject to applicable law and rights in source materials.
You authorize the app to perform local reading, computation, copying, generation of intermediate files, saving, and export necessary for the functions you request. This does not authorize uploading content to us. If you voluntarily send support materials, you grant us only the permission needed to respond to your request and diagnose and resolve that issue.
You must have the right to process, store, export, or send the relevant materials, and respect others’ copyright, image rights, privacy, and other lawful rights. Remove unrelated personal information and trade secrets before sending support materials.
5 Lawful use
You must not use the app for unlawful acts, infringement of others’ rights, distribution of malicious software, or malicious disruption of the app or other systems. Do not remove third-party copyright, license, or attribution notices that must be retained, or impersonate the developer or a rights holder to claim authorization or endorsement.
These requirements do not restrict lawful creative photography, fair use or other statutory exceptions, independent research, or rights granted under open-source licenses. If unsure whether you may process particular materials, first check with the relevant rights holder or an appropriate professional.
6 Third-party software and data
The app may include open-source software, image processing components, star catalogs, lens calibration data, and other third-party resources. Copyright notices, attributions, licenses, and applicable conditions can be found through About and the third-party license and data attribution notices supplied with the app.
Each resource is provided under its own license. If that license conflicts with these terms concerning that resource, it prevails within its scope. These terms do not remove rights you have under open-source licenses. Observe applicable requirements, including retaining attribution, supplying license texts, or other conditions.
Software licenses and data licenses are separate matters. Attribution alone is not permission for commercial use or redistribution. These terms do not expand third-party rights or relieve us of the responsibility to obtain permissions legally required to distribute the app. Naming third parties or data sources does not imply their endorsement.
7 File access and project safety
The app processes local content through files or folders you select and may retain macOS security-scoped bookmarks for the access you grant. Select the scope of access you need. Revoked permissions, moved files, disconnected external drives, or changed synchronization status may prevent a project from reading dependencies or continuing processing.
Keep separate backups of originals and important projects. Do not keep the only copy in temporary folders or on a single storage medium. Saving a project does not necessarily copy all dependencies inside the project file. Before cleaning working storage, migrating devices, or uninstalling, check references to originals and processing results and verify that backups reopen.
For exports, check the destination, filename, overwrite prompts, available space, and resulting file. We do not operate a cloud photo backup or disaster recovery service. These precautions do not reduce any product or data protection responsibilities we have by law.
8 Results and intended use
Stitching, registration, stacking, resampling, lens correction, exposure adjustment, or blending may change images or create new ones. Automated processing may cause misalignment, seams, cropping, color or brightness differences, metadata changes, failures, or other unexpected results. Not every input or device combination will process successfully.
Before overwriting originals, delivering to clients, printing, publishing, or relying on results for decisions, inspect previews, details, export completeness, and necessary metadata. For commercial delivery, arrange quality checks appropriate to the project.
Unless expressly agreed in writing and appropriately validated, the app is not designed for navigation, safety-critical tasks, medical decisions, or scientific measurement requiring certified accuracy. Do not use results that have not been independently verified as the sole basis for such purposes. These statements do not exclude software quality guarantees required by applicable law.
9 Privacy and independent services
The Privacy Policy describes information handling. The current version has no account registration, embedded advertising, or behavioral analytics service, and does not proactively upload photos, capture metadata, projects, or processing results to us. Support materials you voluntarily send are handled under the Privacy Policy.
Apple purchases, downloads, updates, TestFlight, and optional diagnostics, and email, cloud storage, and synchronization services, are subject to the relevant providers’ rules. Saving content in synchronized folders may cause those services to synchronize files. Review the terms and data practices of external services you use.
10 Pricing payment and refunds
Charges, prices, taxes, availability, and purchased content depend on information actually displayed at purchase in the App Store or another distribution channel officially designated by us. Apple processes payments and refund requests made through it under its procedures and applicable law. We will provide reasonable assistance within our responsibilities.
These terms do not indicate that the current version has a subscription or automatic renewal. Subscription conditions apply only if such products are actually offered and the product, billing period, renewal rules, and cancellation method are clearly displayed. These terms alone must not create a new subscription or charge without express agreement.
Refund, price adjustment, and cancellation rules do not limit statutory consumer rights. These terms must not be read as a blanket “no refunds” policy.
11 Test versions
TestFlight and other clearly identified test versions may contain incomplete features, more errors, compatibility issues, or data format changes, and may expire under Apple’s rules or the test information. Back up important files and do not rely on a test version alone to retain the only usable copy of a project.
Test eligibility, duration, feedback, and diagnostics are subject to the relevant testing channel’s rules. Participation does not guarantee a final release, any specific feature, or a free license, and does not mean particular accuracy or compatibility has been accepted as verified.
12 Updates changes and ending use
We may provide updates to fix errors or improve compatibility, security, or features. Their availability and timing depend on development, technical conditions, and distribution platform rules. These terms do not promise indefinite support for a system or file format. Material feature restrictions or the end of support will be communicated, as appropriate, through release notes, app notices, or other reasonable means.
We will not rely solely on a general change clause to arbitrarily remove core features paid for and legally promised, or ongoing services required by law. For material adverse changes, we will meet applicable notice, remedy, termination, or refund requirements.
You may stop use at any time. The license ends if you no longer lawfully hold it, materially breach these terms in circumstances where termination is lawful, or another lawful termination ground applies. Where appropriate and practical, we will explain the reason and allow a reasonable opportunity to remedy it. Termination does not authorize us to delete your originals or projects remotely or invalidate third-party rights that must survive.
13 Intellectual property and general feedback
Rights in proprietary app code, interfaces, documentation, and similar materials belong to us or the relevant rights holders. Apple and third-party software and data providers retain their own rights. Using the app does not transfer ownership of these rights beyond what is needed to lawfully process your own work.
We may use general feature suggestions you voluntarily provide to improve the app if they do not contain personal materials, confidential information, or restricted third-party content. You retain any legal rights in the feedback itself. This does not broaden our use of photos, projects, or personal information you submit. Support materials remain subject to the limitations above and the Privacy Policy.
14 Support and Apple terms
For questions or issue reports, contact gaoxiangsoft@163.com with necessary app version, system information, and reproduction steps. We will handle requests within reasonable capabilities. Unless otherwise agreed or legally required, we do not promise a fixed response time or resolution of every issue.
For Apple distribution, Apple’s store and TestFlight rules, and its applicable Standard End User License Agreement or a legally effective custom license agreement, continue to apply within their respective scope. Merely supplying these Terms of Service does not make them an Apple-accepted custom EULA or replace platform rules that cannot be replaced.
The app’s provider is responsible for its development, maintenance, and support as applicable. Apple’s responsibilities are governed by its applicable terms and law. If the applicable Apple license requires third-party beneficiary or other provisions, that requirement prevails within its scope.
15 Warranties and liability
We will meet product quality, contractual, and consumer protection duties imposed by applicable law. Beyond legal requirements and express commitments we make, we do not additionally guarantee uninterrupted or error-free operation, suitability for every particular purpose, or successful processing of every file.
To the extent permitted by applicable law, we are not responsible for losses caused by matters for which we are not legally responsible, or indirect losses beyond reasonable foreseeability. Responsibility depends on breach, causation, actual loss, and applicable law; a data loss event alone does not mean you bear all responsibility.
These terms do not exclude or limit liability that cannot lawfully be excluded, including liability for intentional misconduct or gross negligence where limitation is prohibited, personal injury, and statutory consumer remedies. Third-party license disclaimers apply only to the extent legally valid.
16 Applicable law and disputes
The formation, validity, performance, and resolution of disputes concerning these terms are determined under the law that legally applies. No choice or interpretation of law removes consumers’ protections under applicable mandatory law.
You may first contact us by email about a dispute. This is not a precondition for court proceedings, complaints, or statutory remedies, and does not pause legal time limits. An unresolved dispute may be brought before a court or other authority with lawful jurisdiction. These terms do not impose mandatory arbitration or require waiver of collective remedies available by law.
17 Changes and other provisions
We may change these terms for changes in features, distribution, or law and reasonably communicate the version and effective arrangements. Material changes affecting rights or obligations will be clearly notified in advance as legally required. Where express agreement is required, continued use alone does not replace it. Changes do not retrospectively remove statutory rights from completed transactions.
If a provision is invalid or unenforceable, the remainder continues to the extent permitted by law. Not immediately exercising a right does not permanently waive it. Read these terms and the Privacy Policy together within their respective scope; personal information processing must still satisfy applicable law.
Chinese and English versions are intended to convey the same content. Differences should be interpreted in context and under applicable law without reducing mandatory rights. For questions about these terms, contact gaoxiangsoft@163.com.
