Scope of this resource

Publisher and purpose

This website is published by Mangowanderwagon SAS, 6 rue de la Monnaie, 35000 Rennes, France, SIREN 922 671 345. Contact: [email protected].

The material is general educational and editorial information about residential planetariums. Browsing the site, using its composer or sending an enquiry does not create an architectural, engineering, installation or advisory engagement.

No project-specific approval

Diagrams are schematic and not to scale. They do not provide construction dimensions, structural calculations, fire-safety provisions, electrical instructions or verified performance predictions. Do not use them as installation drawings or instructions for altering a building.

Seek appropriately qualified professionals for structural, electrical, acoustic, accessibility, ventilation and safety decisions. Verify current product documentation, content licences, local rules and applicable standards before relying on them in a project.

Information and references

We aim for clear and useful explanations, but technology and product availability change. Content may contain errors or omit circumstances relevant to a particular installation. We do not guarantee that every page is complete, current or suitable for an individual purpose.

References to manufacturers, institutions, standards or venues identify useful context. They do not imply sponsorship, affiliation, approval or endorsement. External websites are controlled by their respective operators, and their terms apply when you visit them.

Local composer

The contact composer only formats text in your browser. It does not send an email, reserve a service, register a project or calculate a price. Clipboard and download functions depend on browser support and permissions. Review your brief and remove sensitive details before sharing it.

You remain responsible for your local copies and any subsequent transmission. The site does not promise storage or recovery of entered text. Read the Privacy notice for the distinction between local processing and email correspondence.

Permitted use and intellectual property

You may read the site, link to its pages and make reasonable personal reference copies. Original editorial text, diagrams and presentation are protected by applicable intellectual-property law. Third-party names and assets remain subject to their owners' rights and relevant licences.

Do not republish substantial original material commercially without permission, misrepresent the publisher's statements, interfere with the website or attempt unauthorised access. Statutory quotation, accessibility and other lawful exceptions remain unaffected.

Availability and liability

Access may be interrupted for technical, maintenance or security reasons. To the extent permitted by applicable law, we are not responsible for losses resulting from reliance on general information as though it were project-specific professional advice, or for third-party services outside our control.

Nothing in these terms excludes or limits liability that cannot lawfully be excluded or limited, including applicable mandatory consumer rights. Any limitation is subject to the law governing the particular circumstances.

Applicable law and changes

These terms are governed by French law, without depriving consumers of mandatory protections available under otherwise applicable law. Any dispute must be handled by a competent court under the relevant jurisdiction rules; this statement does not impose an exclusive venue contrary to mandatory rights.

We may update these terms as the resource changes. The current version is available on this page. Questions about use or permissions can be sent to the publisher's email address.
