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.
RACKWATT IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION ANY IMPLIED WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR ACCURACY. No guarantee is made that the app, its calculations, or its reference content are accurate, current or complete.
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.
To the maximum extent permitted by law, total aggregate liability arising from or relating to the app shall not exceed the greater of the amount you paid for the app and its in app purchases in the twelve months preceding the claim, or fifty United States dollars. Some jurisdictions do not allow certain exclusions or limitations, so parts of this section may not apply to you. Nothing here limits liability that cannot lawfully be limited.
You agree to indemnify and hold harmless the developer from any claim, liability, damage, loss or expense, including reasonable legal fees, arising from your use of the app, your reliance on its output, or your breach of these terms.
These terms are governed by the laws of the State of Georgia, United States, without regard to its conflict of law rules. Any dispute shall be brought exclusively in the state or federal courts located in Georgia, and you consent to that jurisdiction.
These terms are presented in the app as a user agreement that must be accepted before use. They are in addition to Apple’s Standard Licensed Application End User License Agreement, which also applies. Apple is not a party to these terms.
These terms may be updated; the date above reflects the current version. Continued use after changes means acceptance.
