Terms of Use

Effective April 4, 2025 · Papertrail B.V. · Amsterdam, Netherlands

Who may use Bitfrost

Bitfrost is available to individuals and organisations aged 18 or older. By using the service you confirm you have the authority to bind yourself or your organisation to these terms.

What the service does

Bitfrost embeds a cryptographic watermark into JPEG images at the moment of capture and provides a public verification endpoint to check whether a given image retains that watermark unmodified.

The watermark is a signal of authenticity, not an absolute legal guarantee. Bitfrost does not certify the content of an image — only that it has not been modified since it was signed by this service.

Acceptable use

You may use Bitfrost for any lawful purpose. You may not:

Your content

You retain ownership of all images you process through Bitfrost. We store a hash-based record of each operation for verification purposes, but we do not retain copies of your images beyond the duration of the request.

API and rate limits

Usage is subject to the limits of your plan. We reserve the right to throttle or suspend access if usage materially exceeds your plan or poses a risk to service stability.

Disclaimer of warranties

The service is provided "as is" without warranties of any kind, express or implied. We do not warrant that the service will be error-free, uninterrupted, or that the watermark will be accepted as evidence in any legal or administrative proceeding.

Limitation of liability

To the maximum extent permitted by Dutch law, Bitfrost's aggregate liability for any claim arising out of these terms is limited to the amount you paid us in the three months preceding the claim. We are not liable for indirect, incidental, or consequential damages.

Termination

You may stop using the service at any time. We may suspend or terminate accounts that violate these terms, with reasonable notice where feasible.

Governing law

These terms are governed by Dutch law. Disputes are subject to the exclusive jurisdiction of the courts of Amsterdam, the Netherlands, unless mandatory consumer protection law in your country provides otherwise.

Changes

We will provide at least 14 days' notice of material changes by email. Continued use after the effective date constitutes acceptance.
