By downloading or using RackWatt, you agree to these terms.
RackWatt is a reference and planning aid for qualified data center professionals. It is not a substitute for the site approved procedures, the manufacturer manuals, NFPA 70E, the site arc flash study, or the engineer of record. Where RackWatt and any of those disagree, they govern, not the app.
Critical systems are frequently energized by design, and available fault currents can be very high. Work on energized equipment and any safety critical condition must be performed by qualified persons under an approved procedure and the applicable safety program, working from the site arc flash study. Never break redundancy without an approved procedure, awareness of the current redundancy state, and a known back out plan. RackWatt never authorizes anyone to perform work they are not qualified and authorized to do.
Calculator outputs and reference entries are planning estimates and curated summaries provided in good faith without warranty of accuracy or completeness. A qualified person must verify all results against the governing documents before acting on them. You assume all risk arising from use of the app.
RackWatt Pro is offered as a monthly subscription or an annual subscription, billed through your Apple account. There is no lifetime option. Subscriptions renew automatically until cancelled in your Apple account settings at least 24 hours before the period ends. Refunds are handled by Apple under their standard policies.
Procedures, records, forms, photos, signatures, and PDFs you create belong to you and stay on your device. You are responsible for their contents and for where you choose to send them.
To the maximum extent permitted by law, ThrasherApps and Chris Thrasher are not liable for any indirect, incidental, consequential, or special damages, or for injury, equipment damage, downtime, or code violations arising from use of or reliance on the app.
These terms may be updated; the date above reflects the current version. Continued use after changes means acceptance.
