Welcome to CrystalLab (available at crystal-lab.org, hereinafter referred to as "this Website"). This Website is a non-profit educational platform for crystal chemistry enthusiasts, dedicated to providing learning resources on crystal growing, chemical experiments and related scientific knowledge. Before using this Website, please read this Disclaimer carefully. Any access to or use of this Website constitutes your full acknowledgment that you have read, understood and accepted all of the following terms.

1. Accuracy of Content

All crystal growing guides, experimental methods, chemical information, coordination compound synthesis tutorials and related materials provided on this Website are for reference and educational exchange purposes only. Although we strive for accuracy, timeliness and completeness, given the professional complexity of chemistry and the continuous evolution of knowledge, this Website cannot guarantee that all information is absolutely accurate, complete or applicable at all times.

Users should independently assess the applicability of the information and consult authoritative literature or qualified professionals before conducting any experiments. This Website assumes no responsibility for any direct or indirect consequences arising from reliance on its content.

2. Safety Responsibility

Crystal growing experiments involve the purchase, preparation and handling of chemicals, some of which are corrosive, toxic or otherwise hazardous. Before conducting any experiment, users must possess the necessary fundamental knowledge of chemical experimentation, fully understand the Safety Data Sheets (SDS/MSDS) of all chemicals used, and take appropriate personal protective measures (such as goggles, protective gloves and ventilation).

Users must independently ensure that their experimental operations comply with all applicable local laws and regulations concerning chemical management, laboratory safety and environmental protection. All legal consequences arising from violations of local regulations shall be borne solely by the user.

3. Intellectual Property

The copyright and other intellectual property rights in all original content of this Website (including but not limited to written tutorials, images, diagrams, website design, code and videos) belong to CrystalLab or the respective content contributors. No individual or organization may copy, republish, adapt or use such content for commercial purposes in any form without explicit written authorisation.

All third-party literature, images or data quoted on this Website are attributed to their sources. If you have any copyright concerns, please contact us using the contact information at the end of this page, and we will verify and handle the matter promptly.

By submitting content to this Website, users are deemed to have granted this Website a non-exclusive, worldwide, royalty-free licence to use the content within reasonable limits, including display, editing, archiving and distribution; this does not affect the contributors' copyright in their original works. Where a contributor exercises the right of erasure under the Privacy Policy, the licence terminates accordingly (see the User Submissions clause of the Terms of Service).

Attribution must accurately reflect ownership: where both the crystal and the photograph were produced by the submitter, attribution may be given as "Author / Grower"; where the crystal was purchased or grown by another person and only the photograph was taken by the submitter, the submitter holds rights only in the photograph, must be attributed as "Photographer" with the crystal source noted, and the submission will be verified and processed separately by this Website. Any ownership disputes, claims or litigation arising from a submitter's failure to truthfully declare the source, misappropriation of another's growing results, or use of unauthorized materials shall be borne entirely by the submitter, who shall bear all legal responsibility and costs. This Website assumes no joint or vicarious liability and reserves the right to recover from the submitter any losses suffered by this Website as a result.

4. External Links

This Website may contain links to third-party websites (such as references, purchasing channel recommendations and community platforms).

These services are operated independently by their respective providers, are subject to their own terms of service and privacy policies, and this Website assumes no responsibility for their service quality, data processing practices or availability.

6. AI Assistant

This Website provides an AI assistant ("Steward") service powered by the Dify platform, designed to help users quickly access crystal chemistry knowledge. Please note the following important matters:

• AI assistant responses are generated based on training data and may contain errors, omissions or outdated information; they do not constitute professional chemical advice.
• Please do not enter personal sensitive information (such as your name, contact details or home address) into the AI assistant.
• AI assistant conversation data is processed by the Dify platform, subject to its privacy policy; this Website cannot control how that platform processes the data.
• Any experimental procedures or chemical quantity suggestions provided by the AI assistant must be independently verified by the user before being used as a reference; this Website assumes no responsibility for any consequences of relying on AI-generated suggestions.

7. Advertising Services

This Website displays third-party advertisements through Google AdSense to sustain its normal operations. Ad content is automatically served by Google based on users' browsing behaviour and interest preferences, and this Website assumes no responsibility for the accuracy, legality or quality of the products or services promoted in the advertisements.
