What happens if I don't like the result?

Every credit comes with our Result Guarantee. If you're not satisfied, we refund your credit instantly — no questions asked.

Do I need experience with image processing software?

Not at all. Cosmos Darkroom was built for everyone — from complete beginners to seasoned imagers. The automated pipeline handles the complex processing.

Does it work with my telescope?

Yes — Cosmos Darkroom works with any telescope: smart telescopes (Seestar, Dwarf, Vespera, Unistellar, Celestron), Newton reflectors, refractors, and any optical setup.

How long does processing take?

Most images are ready in 30 seconds to 2 minutes, depending on file size. Pro subscribers get priority processing.

Do I need a powerful computer?

No. Everything runs on our GPU-accelerated cloud. All you need is a web browser — works on any device.

1. General Principles

Cosmos Darkroom is a SaaS (Software as a Service) platform for AI-powered astrophotography image processing. This policy describes the rules applicable to subscription and processing credit refunds.

2. Right of Withdrawal (EU/FR Consumers)

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.

If you have not used any credits and are within the 14-day legal period following your subscription, you may exercise your right of withdrawal by contacting us via email.

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.

4. Result Guarantee — Credit Refund

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
The request must be made within a reasonable time after processing

5. 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, without compensation or refund.

6. Service Unavailability

Cosmos Darkroom is hosted on private infrastructure (see our Terms of Service and Legal Notice). In case of temporary Service unavailability, no compensation, refund, or subscription extension shall be due.

7. Exceptional Requests

Any refund request not covered by the cases described above will be reviewed on a case-by-case basis, at the Publisher's sole discretion. For any request, contact us at: sebastien.voerman@gmail.com

8. Payment Processor

All payments are processed by Stripe. Cosmos Darkroom does not store any banking information. Any approved refunds will be processed via Stripe to the original payment method, within 5 to 10 business days.
