MineralCalc is a static website with no user accounts and no login. We collect personal information in only one situation:
MineralCalc uses your browser's local storage for two things, both of which stay on your device and are never transmitted to us:
To operate the site, we rely on a few third parties, each governed by its own privacy policy:
A waitlist email address is used only to contact you about the Lease Analyzer feature, including launch notice and early-access details. We do not sell, rent, or trade your email address. You may ask us to delete it at any time by emailing alexogerardi@gmail.com.
The Lease Analyzer reads a lease PDF entirely within your browser and screens it for common terms and clauses. Because the parsing happens on your device, there is no upload step and no server copy of your lease — we never see the document, its contents, or the results.
The analyzer matches known lease language patterns. It is a screening aid, not a substitute for legal review: it can miss non-standard drafting, riders, and exhibits, and clauses it does not flag may still be present. Where a document is a scan, the text is recovered by automated recognition and may contain misread characters; the analyzer tells you when it relied on recognition, and shows the text behind every finding. Have a licensed landman or oil and gas attorney review any lease before signing.
The well lookup uses a periodically refreshed snapshot of public records published by the Oklahoma Corporation Commission (completion and intent-to-drill filings). The snapshot is served as static files from this site; the date it was built is shown in the lookup. Initial test rates are operator-reported and describe a well's early performance, not its average or current production. Verify current well status with the OCC directly.
MineralCalc is intended for adults making decisions about mineral and royalty interests. It is not directed at children under 13, and we do not knowingly collect information from them.
We may update this policy as the site evolves — particularly when the Lease Analyzer launches. Material changes will be reflected in the "Last updated" date above.
Royalty income depends on many real-world variables this tool cannot fully capture — actual well performance and decline behavior, volatile commodity prices, specific lease language (including post-production deduction and shut-in clauses), title and ownership complexity, regulatory action, and operator decisions. Results may differ materially from actual outcomes. Severance tax rates, market benchmarks, well records, and other reference figures are provided for convenience and may not reflect current law, current production, or current conditions; verify them with the relevant authority.
The Lease Analyzer's findings are automated pattern matches and may be incomplete or wrong for your document. The Oklahoma well data is a third-party public snapshot that may be outdated or contain errors originating with the filings themselves. Do not rely on either as the sole basis for a decision.
The site is provided "as is" and "as available," without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the site will be uninterrupted, error-free, or that calculations are accurate or complete.
To the fullest extent permitted by law, MineralCalc and its creator are not liable for any direct, indirect, incidental, consequential, or special damages — including lost income, lost profits, or lost opportunities — arising from your use of, or reliance on, this site or its outputs. You use the tool and act on its results at your own risk.
You agree not to misuse the site, including attempting to disrupt its operation, scrape it at abusive volumes, or use it for any unlawful purpose.
