Terms, Refunds & Privacy

Last updated 25 August 2026

Flagstone is a product of osOS. By using Flagstone to assess a report, you agree to the terms below. Please read them — especially the refund and “not advice” sections.

What Flagstone does

Flagstone reads an uploaded NI 43-101 mining technical report, benchmarks its disclosed figures against comparable projects, and returns a letter grade assessing how well the report’s disclosed work supports the confidence its study stage implies. It assesses the defensibility of the report — not the quality of the underlying project, and not whether the report’s conclusions are correct.

Not investment or professional advice

A Flagstone grade is an automated, informational assessment. It is not investment advice, financial advice, or a professional or legal opinion, and it is not a substitute for your own due diligence or the judgement of a qualified person. osOS is not a licensed financial adviser. You are responsible for any decisions you make. The assessment is provided “as is,” without warranty of accuracy, completeness, or fitness for a particular purpose, to the fullest extent permitted by law.

Pricing & payment

Each report assessment costs US$199, charged per upload through Stripe. We never see or store your card details. You are charged only after your file passes a processability check; if it can’t be assessed, you are not charged.

Refunds

Because a report is delivered to you immediately and is a digital good, sales are generally final. However:

Your files & privacy

Your report & access

After payment you receive a private link to your report. Keep this link — it’s how you re-open your report. Report links are unguessable but are not password-protected, so anyone you share the link with can view that report.

Acceptable use

Upload only reports you have the right to submit. Don’t attempt to disrupt, overload, or reverse-engineer the service. We may decline or remove access for misuse.

Changes

We may update these terms as the product evolves; the “last updated” date above will change accordingly. Continued use means you accept the current terms.

Contact & support

Questions, problems, or refund requests: ossawilliams@gmail.com. We aim to reply within a couple of business days.
