PLATFORM TERMS & CONDITIONS

Preamble

Thank you for choosing Spacetime Pictures.

The purpose of these Platform Terms & Conditions is to govern the access to and use of the website https://spacetimepictures.com and the services offered thereon (the "Platform").

The Platform is operated by Spacetime, a French simplified joint-stock company (SAS), registered with the Chartres Trade and Companies Register under number 992 229 013, having its registered office at 10 rue de la Paix, 75002 Paris, France (hereinafter "Spacetime").

Spacetime operates the Platform and provides the tools and technical means allowing the upload and download of astrophotographic datasets, the publication of previews, and the creation of processed images.

When you access the Platform for the first time, you must unreservedly accept these Platform Terms & Conditions. If you do not agree, you must not use the Platform.

Definitions

For the purposes of these Platform Terms & Conditions:

• "Dataset" means calibrated and stacked astronomical data files provided in FITS format and made available on the Platform, together with associated files and technical/descriptive information.
• "Processed Image" means any full-resolution image (including but not limited to TIFF or PNG files) created by a Subscriber through the processing of a Dataset.
• "Preview" means a reduced-resolution, compressed, or otherwise adapted representation of a Processed Image displayed on the Platform for browsing, discovery, ranking, or community interaction.
• "Database" means the structured collection of Datasets organized, indexed, classified, and presented by Spacetime on the Platform.
• "User" means a natural person accessing the Platform without creating an account or subscribing.
• "Subscriber" means a natural person acting in their own name or on behalf of a legal entity, who has created an account on the Platform.
• "Premium Subscriber" means a Subscriber holding an active paid subscription (monthly or annual).

Article 1 - Services Offered by the Platform

Spacetime aims to facilitate the distribution of astrophotographic data through a structured, transparent, and fair model.

Spacetime regularly feeds the Platform with Datasets consisting of master files in FITS format, together with descriptive and technical files associated with such Datasets (the "Datasets"). The process for contributing Datasets is described in Article 4.

The content of the Database is checked, indexed, classified, and presented by Spacetime on the Platform before being made available to Subscribers.

Subscribers may download the Datasets to process them and create their own Processed Images. Previews may be published on the Platform to promote community interaction and discovery.

With Spacetime, dataset contributors may monetize their Datasets, and image processors may create and publish their own results from those Datasets.

Article 2 - Provisions on the Database

2.1 Copyright and database rights

Users and Subscribers are informed that the architecture, selection, presentation, and layout of the Database (without this list being exhaustive) are protected by copyright and/or database rights.

The Subscriber has a limited right of use of the Database for internal needs, with a view to accessing, consulting, extracting, and reusing a limited and insubstantial part of the Database within the strict limits of the License granted under Article 5.

Accordingly, the Subscriber has no right to reproduce, adapt, translate, or represent the Database outside the limits strictly defined in these Platform Terms & Conditions.

2.2 Derivative work

The Subscriber shall refrain from modifying or creating a derivative work of the Database as such without the prior written consent of Spacetime.

For the avoidance of doubt:

• Processed Images and Previews are not derivative works of the Database for the purposes of this Article 2.2.
• Any restriction in this Article 2.2 applies only to derivative works of the Database itself (e.g., reproductions or reorganizations of the Database), and does not limit the creation, ownership, publication, or commercial exploitation of Processed Images created from Datasets under Article 5.

2.3 Correcting errors

Spacetime reserves the right to correct errors that may affect the Database, without implying any commitment to provide assistance, maintenance, or services associated with the Database.

2.4 Internet network malfunctions

The Subscriber acknowledges that the Internet network, and any telecommunication network used for data transmission, may experience congestion, outages, maintenance, or events beyond Spacetime's control.

Spacetime shall not be liable in case of malfunction or interruption caused by communication networks or any event beyond Spacetime's reasonable control.

Spacetime may develop the Database according to the evolution of computer techniques and may, at its sole choice, make changes of format or language. Spacetime will inform Subscribers by any means, including a written notification on the Platform.

Spacetime grants the Subscriber a personal, non-transferable, non-exclusive license to download and process Datasets solely for the purpose of creating Processed Images (the "License").

Processed Images – ownership and commercial exploitation

The Subscriber retains all intellectual property rights attached to their Processed Images and may publish, distribute, and commercially exploit them worldwide and without limitation in time (including prints, licensing, books/magazines, exhibitions, competitions, professional portfolios), provided that the Subscriber complies with the attribution obligation below and the Dataset restrictions in Article 5.3.

Attribution obligation (mandatory for public publication)

When publishing or distributing a Processed Image (including online or in print), the Subscriber shall provide proper attribution to the source dataset and the dataset contributor, at a minimum as follows:

Previews and Spacetime's rights (Platform & promotion)

By uploading or publishing a Preview on the Platform, the Subscriber grants Spacetime a royalty-free, non-exclusive, worldwide license to host, display, reproduce, distribute, and publicly communicate such Preview solely for operating, presenting, and promoting the Platform (including on Spacetime's social media, newsletters, and marketing materials).

This license applies exclusively to Previews and does not extend to full-resolution Processed Images.
