Terms of Use
By downloading, installing, or using JobRig, you agree to these terms. If you do not agree, please do not use the app.
1. What JobRig is (and what these terms cover)
JobRig is a set of calculation tools for tradespeople. It computes geometry and quantities from the numbers you enter. It is a working aid, not a substitute for professional judgment, measurement verification, or compliance with laws and building codes.
These terms are an agreement between you and the developer, Raz Sharabi (Israel): "we", "us". They cover the JobRig app and the jobrig.app website; the website is informational and provided as-is, and the warranty, liability, and dispute sections below apply to it too.
2. Who may use JobRig
You need the legal capacity to agree to these terms. JobRig has no accounts and collects nothing about you beyond what the privacy policy describes (anonymous crash reports and, only if you opt in, anonymous usage events), so there is no hard age gate; if you are a minor where you live, use JobRig only with a parent's or guardian's consent; and note that the responsibility sections below apply with full force: building work is adult work.
3. Your license to use JobRig
We grant you a limited, personal, non-exclusive, non-transferable, revocable (as set out in §11) license to install and use JobRig on devices you own or control, for your own work (including your own commercial trade work; that is what it is for), subject to these terms and the usage rules of the app store you got it from.
Your outputs are yours to use. Results you compute, and the images or PDFs you export from JobRig, may be freely used and shared for your own work, including with clients. The responsibility and disclaimer sections (§§4 to 8) apply to exported results exactly as they do in-app, and the rule below against presenting output as certified or code-approved applies to shared files too.
What the license does not allow. Don't:
- copy, modify, translate, or create derivative works of the app;
- distribute, sell, resell, rent, lease, lend, or sublicense it;
- reverse-engineer, decompile, or disassemble it, except to the extent the law expressly permits it despite this term;
- remove or alter any proprietary or attribution notices;
- misrepresent the app or its results (for example, presenting its output as certified, code-approved, or professionally endorsed);
- use it in violation of any law, or use the JobRig name or brand to imply endorsement.
The app, its design, and its content are the developer's intellectual property. All rights not expressly granted are reserved.
4. Your responsibility for results
- Verify before you build. You are responsible for checking every measurement, calculation result, and cut before acting on it. Materials, tools, and job sites vary; a calculator cannot see your site.
- Building codes are yours to check. Where a JobRig tool offers reference values (for example, maximum gaps, riser ranges, or similar reference numbers), they ship as editable, common-practice reference defaults. They are not building-code requirements and JobRig makes no representation that any value complies with any code, standard, or regulation in your location. Always confirm the requirement that applies to your work against the building code as adopted and amended in your jurisdiction: codes differ by country, region, municipality, and project type, and local amendments routinely change the base numbers.
- Professional advice. JobRig does not provide engineering, architectural, or construction advice, and using it creates no engineer-client, architect-client, or any other professional relationship between you and the developer. For load-bearing, structural, safety-critical, or regulated work, consult a qualified professional.
- Garbage in, garbage out. Results are computed from the numbers you enter. A mistyped digit, a misread tape, or the wrong unit produces a wrong answer delivered with full confidence. Checking your inputs is part of using the tool.
5. Measurement, units, and precision: know the limits
JobRig's math is careful, but every calculator has edges. Know them:
- It is not a measuring instrument. JobRig measures nothing itself; it only computes from numbers you type. It is not certified for legal metrology or trade use (such as buying or selling by measure) in any jurisdiction.
- Unit conversion and rounding. Converting between metric and imperial, between degrees, percent, and pitch, or between decimals and tape fractions involves rounding. Imperial tape fractions round to the tape fineness you select in Settings. Displayed values, including pitch rise, are rounded to a practical precision, and over long runs or chained calculations small rounding differences can compound. Where exactness matters, work in one unit system and verify the final figure independently.
- Near-vertical readings. Slope (percent and pitch) has no finite value at vertical; at or extremely close to vertical, the app displays ∞ rather than a misleadingly huge number. That display is a signal, not a measurement.
- Display fit. Long values may be shortened or truncated to fit the screen, and the drawn triangle is an illustration: never measure off the screen.
None of this is a defect; it is the nature of digital calculation. It is listed here so you can work around it, and so it is clear that you accept these characteristics when you use the app.
6. Safety-critical work: assumption of risk
Some things built with these numbers can hurt someone if they are wrong: stairs, railings, guards, ramps, and anything load-bearing or fall-protective. For that work:
- treat every JobRig figure as a starting point that requires independent verification;
- confirm compliance with the building code as adopted and amended where the work is located;
- involve a qualified professional wherever the work is structural, safety-critical, or regulated.
To the extent permitted by the law where you live, you assume the risk of relying on calculated values for safety-critical structures without independent verification. Nothing in this section excuses us from liability that the law does not allow us to exclude (see §8).
7. No warranty
JobRig is provided "as is" and "as available." To the maximum extent permitted by applicable law, we disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose, accuracy, and non-infringement. We do not warrant that the app is error-free, that it will be uninterrupted, maintained, or updated, or that results are accurate or suitable for your specific situation. No advice or information, oral or written, obtained from us creates any warranty not stated in these terms. Where the law implies warranties that cannot be disclaimed, they apply to the minimum extent required (see the carve-outs in §8).
8. Limitation of liability
To the maximum extent permitted by applicable law, we shall not be liable for any indirect, incidental, special, consequential, or exemplary damages (including lost profits, wasted materials, project delays, property damage, or personal injury) arising from the use of, or inability to use, the app, the website, or their results. Where liability cannot be excluded, it is limited to the amount you paid for the app in the twelve months before the claim.
What this section never takes away. Some places do not allow parts of the paragraph above, and there we do not apply them:
- Everywhere: nothing in these terms excludes or limits liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for our intentional misconduct or gross negligence, wherever the law does not allow that liability to be excluded.
- Nothing in these terms limits rights that consumer-protection law grants you and that cannot be waived.
- United Kingdom: nothing excludes or limits liability for death or personal injury caused by negligence, or for fraud or fraudulent misrepresentation.
- EU/EEA consumers: you keep every non-waivable right under the mandatory consumer law of your country of residence.
- Australia: our services come with guarantees that cannot be excluded under the Australian Consumer Law; where that law permits, our liability is limited to resupplying the service or paying the cost of resupply.
- Everywhere else: where a law does not allow an exclusion or limitation in this section, our liability is limited to the minimum extent that law permits.
9. Your indemnity to us
If someone brings a claim against the developer because of (a) your use or misuse of the app or its results, (b) something you built, installed, or specified in reliance on the app, or (c) your breach of these terms or of applicable law, you agree to indemnify the developer: that is, to cover the resulting damages, losses, and reasonable costs, including legal fees. This obligation does not apply where, and to the extent, the mandatory consumer law of your country of residence does not permit it. It also does not apply where, and to the extent, a claim results from our own breach of these terms, our negligence, or a defect in the app itself.
10. Privacy
The privacy policy at jobrig.app/privacy describes what the app and the website do and don't collect. It is part of these terms.
11. Termination and discontinuation
- You can end this agreement at any time by deleting the app.
- We may modify, suspend, or discontinue the app, the website, or any feature at any time, without liability to you. Because JobRig runs entirely on your device, discontinuation does not reach into your phone: discontinuing the app does not by itself disable a copy already installed on your device, though store or operating-system changes beyond our control may eventually break it, and no further updates or support would follow.
- We may revoke your license if you materially breach these terms.
12. App-store terms (Apple and Google)
These terms sit alongside the terms of the store you got the app from. On Google Play, Google's terms of service govern the download and delivery of the app; these terms govern your use of it. On Apple platforms, Apple's standard Licensed Application End User License Agreement (the Apple EULA) governs your license to the app, and these terms apply as supplemental end-user terms alongside it.
For users on Apple platforms, the following provisions apply:
- These terms are concluded between you and the developer only, not Apple. The developer, not Apple, is solely responsible for the app and its content, and Apple has no obligation whatsoever to furnish any maintenance or support for it.
- In the event of any failure of the app to conform to any applicable warranty, you may notify Apple, and Apple will refund any purchase price you paid (for a free app: nothing to refund); to the maximum extent permitted by law, Apple has no other warranty obligation whatsoever with respect to the app.
- The developer, not Apple, is responsible for addressing any claims by you or any third party relating to the app, including product-liability claims, claims that the app fails to conform to any legal or regulatory requirement, and claims under consumer-protection, privacy, or similar laws.
- In the event of any third-party claim that the app infringes intellectual-property rights, the developer, not Apple, is responsible for the investigation, defense, settlement, and discharge of that claim.
- You represent and warrant that (i) you are not located in a country subject to a U.S. Government embargo or designated by the U.S. Government as a "terrorist supporting" country, and (ii) you are not listed on any U.S. Government list of prohibited or restricted parties.
- Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them against you.
- You must comply with applicable third-party terms of agreement when using the app (for example, your wireless data agreement).
Export compliance (all platforms): you agree to comply with all applicable export and re-export control laws and regulations in your use of the app.
13. Feedback
If you send us ideas, suggestions, or feedback, you grant us a royalty-free, perpetual, irrevocable, worldwide, transferable, sublicensable license to use them, without restriction, obligation, or compensation.
14. Third-party components
JobRig includes permissively licensed open-source components, including the Hugeicons icon set (MIT license), Lucide icons (ISC license), the Ionicons and Material Design Icons sets bundled via Expo (MIT and Apache-2.0 licenses), the Instrument Sans typeface (SIL Open Font License), and the React Native / Expo framework libraries and SDKs (MIT and similar licenses). Attribution for the bundled icon sets is maintained in the app's source code, per the project's LICENSES.md. Those components remain under their own licenses; nothing in these terms modifies them.
15. Force majeure
We are not liable for any failure or delay caused by events beyond our reasonable control, including natural disasters, war, terrorism, labor disputes, internet or infrastructure failures, acts of government, and app-store or operating-system platform changes.
16. Governing law and disputes
- Talk to us first. Before starting any formal proceeding, email us (the contact address is at the top of these terms) with a description of the issue, and give us 30 days to resolve it informally. Most things turn out to be a bug report, not a lawsuit. This step does not limit any right you have to go directly to a court or authority, to seek urgent or interim relief, or to act within a legal deadline.
- Governing law and venue. These terms are governed by the laws of the State of Israel, without regard to conflict-of-law rules, and any dispute not resolved informally shall be brought in the competent courts of Israel.
- Consumer savings. If you use JobRig as a consumer, nothing above takes away mandatory protections of the law of your country of residence, including, where that law provides it, the right to bring or defend proceedings in your home courts.
17. General
- Severability. If any term is held unenforceable, the rest of these terms stay in full effect. Where the law of your country allows a term to be reduced so that it becomes valid, it applies as so reduced; where that law does not, the term simply does not apply and the rest stand.
- Waiver. Our not enforcing a term is not a waiver of it.
- Assignment. You may not assign or transfer these terms. We may assign them to a successor of the JobRig product (for example, a company formed to carry it), with notice under §18.
- No third-party beneficiaries. Except for Apple and its subsidiaries as described in §12, these terms create no rights enforceable by anyone other than you and us.
- Entire agreement. These terms, together with the privacy policy (and, on Apple platforms, the applicable Apple EULA provisions referenced in §12), are the entire agreement between you and us about the app and the website.
- Survival. Sections that by their nature should survive the end of this agreement (including §§4 to 9, the Apple and export provisions of §12, and §§13 to 17) survive it.
18. Changes to these terms
These terms and the app may change. Material changes get reasonable advance notice (a note in the app, on the store listing, or at jobrig.app) and a new effective date before they take effect; we will not rely on continued use alone as acceptance of a material change without having given that notice. Non-material fixes (clarity, typos) may be made at any time. Continued use after a change takes effect is acceptance of it.
Appendix: the in-app reference-defaults note
When a tool with editable reference defaults opens, the app shows this notice:
Defaults are references, not rules. Values like the max gap are common-practice starting points, not building-code compliance. Codes vary by location; check yours. Every default is editable.
Section 4 sets out the full legal position behind it; the note's own wording lives here.
