Terms of Service

TechBench by NEXASPHERE

Effective Date: May 18, 2026 · Operator: NEXASPHERE INC. (Delaware, USA) · Contact: [email protected]

1. The service

TechBench (“the App”) is an iOS field-operations application for solo HVAC and plumbing contractors. The App provides on-device AI quote drafting, branded PDF quote generation, an EPA Section 608 refrigerant cylinder ledger and charge log, customer signature capture, and Section 608 audit export. Version 1 supports a single technician on a single iPhone. All processing happens on your iPhone. NEXASPHERE INC. (“we”, “us”) publishes the App via the Apple App Store. By installing or using the App you (“you”) agree to these Terms.

2. Subscriptions, lifetime purchase, and billing

TechBench offers a monthly auto-renewing subscription at $49 per month with a 7-day free trial, an annual auto-renewing subscription at $469 per year, and a one-time lifetime purchase at $499 covering all v1 updates. An abandon-flow offer of $29.99 for the first month may be presented one time per install at the discretion of the App. After the first month, the abandon-offer subscription renews at the standard monthly rate.

All billing is handled by Apple via StoreKit. You manage your subscription in iOS Settings under your name, Subscriptions, TechBench. Cancel anytime there. Cancellation takes effect at the end of the current billing period. Refunds are handled by Apple under Apple's refund policy at reportaproblem.apple.com. We do not process payments and cannot issue refunds directly.

Prices may change. If we change a subscription price, Apple will notify you and request your consent before the change takes effect.

3. License

Subject to these Terms, we grant you a personal, non-transferable, revocable, non-exclusive license to install and use the App on iOS devices you own or control, for your own professional use as a licensed HVAC or plumbing contractor.

4. Acceptable use

You agree not to:

  • Reverse engineer, decompile, or attempt to extract the source code of the App
  • Use the App in violation of applicable law, including EPA Section 608, state plumbing and HVAC licensing rules, sales-tax law, and consumer-protection law
  • Misrepresent your EPA Section 608 certification number or expiration date in the refrigerant log
  • Use the App to harass, defame, or violate the privacy of any third party
  • Share, sublicense, or resell the App or your subscription
  • Use the App in any way that could harm Apple, NEXASPHERE INC., or other users

5. AI quote drafts are starting points, not professional advice

The on-device AI quote drafter and the deterministic rule-engine fallback both produce a draft line-item list as a starting point for your own review and pricing judgment. The output is not professional engineering, code-compliance, sales-tax, or legal advice. You are solely responsible for reviewing every quote before sending it to a customer, including pricing accuracy, applicable taxes, manufacturer warranty terms, code compliance, and your own licensing obligations. NEXASPHERE INC. is not liable for AI-suggested line items, prices, or terms.

6. EPA Section 608 records are your responsibility

TechBench provides an electronic refrigerant cylinder ledger and charge log, GPS-tagged and SHA-256 hash-signed for audit defensibility. You remain solely responsible for the accuracy of every entry, the validity of your EPA Section 608 certification, compliance with 40 CFR Part 82 and any state-level refrigerant-handling rules, and any record-keeping obligations imposed by your local Air Pollution Control District or equivalent regulator. The App does not constitute a substitute for an authorized recovery-equipment maintenance program, a leak-inspection program, or an EPA-certified records retention policy.

7. Customer signatures and PDFs

When a customer signs a quote, the App stores the signature strokes, timestamp, optional GPS coordinates, and a SHA-256 integrity hash. The App can render a branded PDF for emailing or printing. You are responsible for the accuracy of the quote, for ensuring the customer has authority to sign, and for complying with state-level e-signature laws and consumer-protection requirements (cooling-off rights, etc.).

8. Your content

All shop data, customer records, equipment history, quotes, refrigerant log entries, signatures, and PDFs produced by the App are your content. They are stored exclusively on your device. You retain all rights to your content. We do not access, view, or claim any rights to your content. See our Privacy Policy at /products/iphone/techbench/privacy.

9. Our intellectual property

The App itself, including its code, design, brand, on-device AI prompts, deterministic rule engine, PDF layout, and documentation, is owned by NEXASPHERE INC. and protected by copyright, trademark, and other intellectual-property laws. These Terms do not grant you any rights to our trademarks or brand.

10. No warranty

THE APP IS PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS OR IMPLIED, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE APP WILL BE ERROR-FREE OR UNINTERRUPTED, OR THAT DEFECTS WILL BE CORRECTED.

11. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, NEXASPHERE INC. AND ITS OFFICERS, DIRECTORS, EMPLOYEES, AND AGENTS SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUE, DATA, OR GOODWILL, ARISING OUT OF OR RELATED TO YOUR USE OF THE APP, INCLUDING ANY EPA, STATE, OR LOCAL REGULATORY ACTION ARISING FROM YOUR REFRIGERANT-HANDLING RECORDS. OUR TOTAL CUMULATIVE LIABILITY ARISING OUT OF OR RELATED TO THE APP AND THESE TERMS SHALL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US FOR THE APP IN THE 12 MONTHS PRECEDING THE EVENT GIVING RISE TO THE LIABILITY, OR (B) $100 USD.

12. Indemnification

You agree to indemnify and hold harmless NEXASPHERE INC. from any claims, damages, or expenses arising out of your violation of these Terms, your misuse of the App, your violation of any law (including EPA Section 608, state HVAC and plumbing licensing rules, and consumer protection law), or your violation of any third-party right.

13. Termination

You may stop using the App and cancel your subscription at any time via iOS Settings. We may suspend or terminate your access to the App if you violate these Terms. Provisions that by their nature survive termination (including sections 9, 10, 11, 12, 14, and 15) will survive.

14. Apple-specific terms

You acknowledge that these Terms are between you and NEXASPHERE INC., not Apple. Apple is not responsible for the App or its content. To the extent these Terms conflict with Apple standard end-user license agreement for App Store apps, the relevant provisions of Apple EULA apply. Apple is a third-party beneficiary of these Terms with the right to enforce them against you.

15. Governing law

These Terms are governed by the laws of the State of Delaware, USA, without regard to conflict-of-law principles. Any dispute arising out of or related to these Terms shall be resolved exclusively in the state and federal courts located in Delaware.

16. Changes to these Terms

We may update these Terms from time to time. If we make material changes, we will update the Effective Date above and may also notify you in the App. Your continued use of the App after the changes take effect constitutes your acceptance of the updated Terms.
