Terms of use

This website

The content of rosadebias.com is provided for general information. It is not legal advice, and no statement on this site is a certification of compliance with any law or standard. Validation figures are published with their sources and scope; read them with their guardrails.

The free trial

The Rosa free trial is provided as-is, without warranty, during the trial phase. The shared instance applies fair-use limits (dataset sampling and caps, a monthly job quota, one job at a time). The free trial runs for up to three months per workspace; we may extend it on request, and we give notice before a trial ends. Do not submit data you are not entitled to process. We may suspend access that degrades the service for others. Free tiers may be amended or withdrawn with reasonable notice.

Outputs (debiased datasets, reports, manifests) are yours. The Rosa software, models, and methods remain ours. Dedicated proof-of-concept engagements are governed by their own written terms.

Rosa keeps an immutable Run Manifest for every job indefinitely as its permanent evidence record. The manifest records:

• Per-column statistics - for categorical columns the distinct values and their counts; for numeric columns the minimum, maximum, and standard deviation.
• Bias-detection results - the discriminator's accuracy at recovering the protected attribute and the resulting bias score, plus the post-debiasing residual on training jobs.
• The per-feature debiasing adjustment (diagnose jobs) - indicative of how much each column will be adjusted to remove the protected signal.
• Each feature's association with the protected attribute - its measured univariate association, and on training jobs that association recomputed on the debiased output.
• Job metadata and content hashes - including the SHA-256 input hash, so anyone holding the original file can verify exactly what was processed.

It never holds the row-level data you submitted, the debiased output, or the trained model. By using the service you agree to this retention; keep direct identifiers (names, emails, customer IDs) out of the analysis as ignored columns so they are never recorded.

Liability

To the maximum extent permitted by law, Rosa's liability arising from use of this website or the free trial is excluded. Nothing in these terms limits liability that cannot lawfully be limited. These terms are governed by the law of England and Wales.
