Terms of Use

Effective date: 2026-08-21 · Version 1 · Contact: support@jobrig.app

By downloading, installing, or using JobRig, or by using the jobrig.app website, 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, 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 section 10) 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 with JobRig, and the images or PDFs you export from it, may be freely used and shared for your own work, including with clients. The responsibility and disclaimer sections (sections 4 to 8) apply to those results exactly as they do in-app, and the rule below against presenting output as certified or code-approved applies to them too, shared files included.

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 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 section 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 section 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, or project delays) arising from the use of, or inability to use, the app, the website, or their results.

Whatever the claim is, and however it arises, our total liability to you for all claims taken together is limited to the greater of the amount you paid for the app in the twelve months before the claim, or fifty US dollars. This limit applies to direct loss as well, not only to the kinds of loss listed above, and it applies whether the claim is in contract, in tort, or on any other basis.

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.
• EU/EEA product liability: nothing in these terms affects the rights you have under the EU product-liability rules, which cover software and cannot be signed away by agreement.
• Australia: our goods and services come with guarantees that cannot be excluded under the Australian Consumer Law.
• Everywhere else: the exclusions and limitations in this section apply to the fullest extent that law permits.

9. 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.

10. 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, with reasonable notice where that is practical, and without liability to you. Ending support deletes nothing from your phone, and no further updates or support would follow; store or operating-system changes beyond our control may eventually break an installed copy as well.
• We may require that you run a supported version. The app checks which versions are still supported, as described under Checking for a required update in the privacy policy. Where a version gives wrong results, or breaks a legal or app-store requirement, or where the app has not been able to confirm for a long period which version is installed, we may stop that version from opening. Before we do, the app shows a screen you can dismiss and keep working past for a further period, except where a version is producing wrong measurements, in which case it may take effect at once. Section 3's license is revocable on these grounds as well as for breach.
• We may revoke your license if you materially breach these terms.

11. 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. If anything in these terms conflicts with the Apple EULA, the Apple EULA governs to the extent of that conflict, and only in respect of the matters the Apple EULA actually covers: your license to use the app, and the Apple-specific provisions listed below. Everything else in these terms continues to apply as written, including the limitation of liability in section 8 and the governing law and forum in section 15.

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.

12. 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.

13. 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). The full list, with each component's license, its copyright notice and the complete text of every license involved, is published at https://jobrig.app/licenses. Those components remain under their own licenses; nothing in these terms modifies them.

14. Events outside our control (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.

15. 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.

16. 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 section 17.
• No third-party beneficiaries. Except for Apple and its subsidiaries as described in section 11, 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 section 11), 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 section 3's restrictions and reservation of rights, sections 4 to 9, the Apple and export provisions of section 11, and sections 12 to 16) survive it.

17. Changes to these terms

These terms and the app may change. A material change is one that affects what data is handled, why, or by whom, or that adds a charge, a right or a restriction. When one is made, the published page at jobrig.app/terms carries a new effective date before the change takes effect, and that date is the notice; where a change is significant enough to need saying out loud, the app also shows you a notice the next time you open it after the update that carries it. Non-material fixes (clarity, typos) may be made at any time. Continued use after a change takes effect is acceptance of it.
