Author: Cosmos Darkroom

Last updated: February 17, 2026

1. Purpose

These Terms of Service ("Terms") govern the access and use of the Cosmos Darkroom platform (hereinafter "the Service"), published by Sébastien Voerman (hereinafter "the Publisher"). The Service is a SaaS (Software as a Service) platform for AI-powered astrophotography image processing, accessible via web browser.

The Service's technical infrastructure is operated by the Publisher on infrastructure located in France. The Service does not offer any professional-grade availability guarantee (SLA). The User is hereby informed and expressly accepts this by using the Service.

2. Acceptance of Terms

By creating an account, subscribing to a plan, or using the Service in any way, you ("the User") declare that you have read, understood, and accepted these Terms in their entirety. If you do not accept these Terms, you must not use the Service.

Use of the Service constitutes full and unconditional acceptance of the Terms in effect at the time of use.

3. Service Description

Cosmos Darkroom offers an automated astrophotography image processing service including:

16-step AI processing pipeline
Deep learning noise reduction
Light pollution and gradient removal
Smart star control
Real-time image editor with 15+ adjustments
Export in various formats (JPEG, PNG, 16-bit TIFF)
Night sky observation planner ("Tonight")
Community gallery (Cosmos Feed / Cosmos Gallery)
3D parallax animation video generation from processed images

The Service is an image processing and editing tool. It is in no way a data hosting service.

The sole purpose of the Service is to allow the User to submit astrophotography images for automated processing, in exchange for processing credits.The Publisher does not provide any hosting, persistent storage, backup, continuous file availability, or any service other than image processing.

4. Nature of SaaS Service — Availability

Important: Cosmos Darkroom is an online service (SaaS) that depends on complex technical infrastructure including servers, internet connections, GPUs, and third-party services (NextAuth for authentication, Stripe for payment).

The Service relies on technical infrastructure that may be subject to interruptions. The User acknowledges and accepts that the Service offers no availability guarantee (SLA).

By subscribing, you acquire a defined number of monthly processing credits and access to the features associated with your plan. You do not acquire a right to continuous, uninterrupted access to the Service 24 hours a day, 7 days a week.

Consequently:

The Service may be temporarily unavailable for maintenance, updates, or technical issues, without prior notice
We do not guarantee any specific availability rate (SLA)
Interruptions may occur due to network failures, server outages, power cuts, or any other force majeure event
The Service requires a stable internet connection on your end to function
In case of temporary Service unavailability, no compensation, refund, or subscription extension shall be due

We commit to making our best efforts to keep the Service accessible, but we cannot be held liable for any interruption, regardless of its cause or duration.

5. Subscriptions, Credits, and Billing

Subscriptions are offered as monthly plans (Free, Hobby, Pro). Each plan includes a defined number of image processing credits per month. Payments are processed securely by Stripe.

5.1 Subscription Scope

Your subscription entitles you to a monthly quota of image processing credits and access to your plan's features. A subscription is not a guarantee of permanent and uninterrupted access to the Service (see Section 4).

5.2 Right of Withdrawal

Pursuant to Article L. 221-28 of the French Consumer Code (and Directive 2011/83/EU Art. 16(m)), the right of withdrawal does not apply to contracts for the supply of digital content not supplied on a tangible medium where performance has begun with the consumer's prior express consent and acknowledgment of loss of right of withdrawal. By using your processing credits, you acknowledge that performance of the service has begun and expressly waive your right of withdrawal for consumed credits.

5.3 No Subscription Refunds

All subscriptions are final. No refund, even partial, shall be granted for a current subscription period, for any reason whatsoever (dissatisfaction, unused credits, temporary Service unavailability, change of mind, etc.).

You may cancel your subscription at any time from your account settings or via the Stripe portal. Cancellation takes effect at the end of the current billing period: you retain access to the Service and your remaining credits until that date. No pro-rata refund will be issued.

5.4 Non-Cumulative Credits

Processing credits are allocated monthly and do not roll over from one month to the next. Unused credits at the end of the billing period are forfeited.

5.5 Exclusive Scope of Subscription

The subscription grants only the right to use image processing credits during the current billing period. It does not grant any right of access to the infrastructure, algorithms, AI models, source code, or any other technical component of the Service. The subscription does not constitute a contract for IT services, consulting, maintenance, or technical support.

6. Credit Refund Policy (Result Guarantee)

In the interest of transparency, Cosmos Darkroom offers a Result Guarantee on individual image processing: if you are not satisfied with the result of a specific processing, you may request a refund of the credit used for that specific processing.

This guarantee applies exclusively to the processing credit, not to the subscription itself.It does not result in any monetary refund; the credit is simply re-credited to your account.

7. Image Storage — No Hosting Guarantee

Cosmos Darkroom is not a data hosting service. We do not operate as a hosting provider under applicable law.

Images you upload and processing results are stored temporarily on our servers solely to allow you to access and download them. This storage is a complementary service provided free of charge and without any obligation of result.

Accordingly:

We do not guarantee the preservation, permanence, or integrity of your images on our servers
Your images may be deleted at any time, without notice, for technical, maintenance, storage capacity, or any other reason
You are solely responsible for backing up your original files and processing results
We disclaim all liability for loss, corruption, or deletion of images stored on our servers
It is your responsibility to download your processing results as soon as they are available
The Publisher reserves the right to automatically purge images and processing results after a period at its sole discretion, without prior notification. No minimum retention period is guaranteed

⚠️ Critical recommendation: Always keep a copy of your original files on your own storage devices. Never rely on Cosmos Darkroom as the sole storage location for your images.

8. Processing Quality — User Responsibility

Cosmos Darkroom is an automated AI-powered image processing service. We do not guarantee any specific result, any particular quality level, or any adequacy of the result to your subjective expectations.

The quality of processing results depends on many factors, including:

Source image quality (resolution, signal-to-noise ratio, shooting conditions)
Uploaded file format
Parameters chosen by the user during upload (image type: linear/stretched, Newton mode, star size, stretch intensity, etc.)
Editor adjustments applied (brightness, contrast, curves, levels, etc.)

You are solely responsible for the parameters and adjustments applied to your images.Incorrect settings may lead to unsatisfactory results. We cannot be held liable for results you find disappointing if they stem from inappropriate parameter choices or insufficient source image quality.

This is precisely why we offer the Result Guarantee (Section 6): if a result does not satisfy you, your credit is refunded. This guarantee constitutes your sole remedy.

9. Community Content (Cosmos Feed / Cosmos Gallery)

The Service includes a community gallery allowing users to publish their processed images, comment on, and rate other users' publications.

You are solely responsible for the content you publish on the community gallery
You warrant that you hold the rights to the images you publish
By publishing content on the gallery, you grant the Publisher a non-exclusive, royalty-free, worldwide, sublicensable license to display, reproduce, and distribute such content for the purpose of operating the Service (gallery display, thumbnails, sharing). This license terminates upon deletion of the content or account

Content published on the gallery is publicly visible to all Service users
We do not guarantee the preservation of community content
