Terms of Service

Effective date: August 29, 2026 · Last updated: August 29, 2026

1. Agreement to these terms

These Terms of Service are a binding agreement between you and Henry Labs LLC, a Texas limited liability company doing business as ChemLevel (“ChemLevel,” “we,” “us”), governing your use of the ChemLevel website at chemlevel.com, the ChemLevel application at app.chemlevel.com, any ChemLevel mobile application, and the demo (together, the “Service”).

By creating an account, using the demo, or otherwise accessing the Service, you agree to these terms and to our Privacy Policy. If you do not agree, do not use the Service. If a separate written agreement between your organization and ChemLevel covers the Service, that agreement controls where it conflicts with these terms.

Section 18 limits our liability and Section 21 requires most disputes to be resolved by individual arbitration and waives your right to a jury trial and to participate in a class action. Please read both carefully.

2. Eligibility and authority

You must be at least 18 years old to use the Service. ChemLevel is business software and is not offered to consumers for personal or household use.

If you accept these terms on behalf of an organization — a utility, municipality, resort, or company — you represent that you have authority to bind that organization, and “you” means both you and that organization. The organization is responsible for its members’ use of the Service.

3. What ChemLevel is

ChemLevel records the chemical inventory your team enters — tank levels, cylinder weights, usage, deliveries — and calculates from that history when each chemical is likely to run out, when an order should be placed, and roughly how much to order. It also stores Safety Data Sheets you upload, tracks spend against budgets, and drafts vendor order emails for you to send.

ChemLevel is a record-keeping and planning tool. It does not connect to your SCADA system, level sensors, dosing pumps, or any plant control equipment. It does not measure anything, control anything, or place orders on your behalf. Every reading it works from is entered by a person on your team, and every order is sent by a person on your team.

4. Accounts, roles, and device access

You are responsible for the accuracy of your account information, for keeping your password and device PIN confidential, and for all activity under your account. Tell us promptly at info@chemlevel.com if you suspect unauthorized access.

ChemLevel has two roles. Supervisors can invite and remove members, change chemical and container configuration, edit thresholds and budgets, remove Safety Data Sheets, and see everything in Reports. Operators can log readings and usage, place orders, and attach or replace a Safety Data Sheet, and can see the reports their supervisors permit. Your organization’s supervisors decide who holds which role; we do not adjudicate internal access disputes.

ChemLevel supports unlocking an account on a device with a PIN or, where available, biometrics. These are conveniences for shared plant devices, not a substitute for account security. Anyone with physical access to an unlocked device can see and change that organization’s data, and you are responsible for the devices your team uses.

5. Organizations and ownership of data

You and your organization own the operational data you enter into ChemLevel — readings, usage logs, order and delivery records, vendor and cost information, budget figures — and any documents you upload. You grant us a worldwide, non-exclusive, royalty-free license to host, copy, transmit, display, and process that data solely to provide, secure, and improve the Service, and to comply with law. That license ends when the data is deleted, except for copies in backups until they age out on their ordinary cycle.

We do not claim ownership of your operational data, do not sell it, do not disclose it to other customers, and do not use it to train machine-learning models.

You are responsible for having the right to upload what you upload and for keeping it current. ChemLevel stores and displays the documents you attach; it does not review, verify, correct, or update them.

6. Subscriptions, trials, and billing

ChemLevel is sold as a subscription. Some plans cover a single site; others are priced per site. Plan details and current pricing are shown on our pricing page, and the plan, the number of sites it covers, and the price in effect for your organization are those shown in the Service.

• Trials. We may offer a free trial. At the end of a trial, the organization must subscribe to keep using the Service; unless you subscribe, access ends and the retention period in Section 16 begins. We may change or withdraw trial offers at any time.
• Payment. Subscriptions are billed in advance through Stripe on a recurring basis until canceled. By subscribing you authorize us and Stripe to charge your payment method for the then-current fees and any applicable taxes.
• Renewal. Subscriptions renew automatically for successive terms at the then-current price unless canceled before the renewal date. We will give reasonable advance notice of a price increase affecting your renewal.
• Site count. A plan may cover a fixed number of sites, and the Service will not let you add one beyond that. Moving to a plan that covers more sites is arranged with us, and any change in fee is agreed before it takes effect. Where a plan is priced per site, the fee reflects the number of sites on the subscription. Removing a site from service — archiving it in the app — takes effect at the next renewal.
• Failed payments. If a payment fails we may retry it and will notify you. If it remains unpaid, we may restrict writing to the Service — leaving your data readable — and ultimately suspend or terminate the subscription.
• Cancellation. You may cancel at any time, effective at the end of the current billing period. You keep access for the remainder of that period.
• Refunds. Fees are non-refundable except where required by law or expressly stated in writing. We do not provide refunds or credits for partial periods, unused time, or periods when you chose not to use the Service.
• Taxes. Fees exclude sales, use, VAT, and similar taxes, which you are responsible for except for taxes on our income.

7. Acceptable use

You agree not to:

• use the Service unlawfully, or in a way that violates any regulation applicable to your facility;
• access an organization’s data without authorization, or attempt to defeat the role and permission controls;
• probe, scan, or test the vulnerability of the Service, or breach or circumvent its security or authentication, except under a written authorization from us;
• upload malware, or content that infringes another party’s rights or is unlawful;
• upload a document you do not have the right to store and share, or a document falsely presented as a manufacturer’s Safety Data Sheet;
• scrape, spider, or bulk-extract data from the Service by automated means, or use it to build a competing product;
• reverse engineer, decompile, or disassemble the Service except to the extent applicable law permits despite this restriction;
• resell, sublicense, or provide the Service to third parties without our written agreement;
• impose an unreasonable load on the Service or interfere with its operation or with other customers’ use of it; or
• misrepresent your identity or your authority to act for an organization.

We may investigate suspected violations and take appropriate action, including removing content, suspending access, and reporting to law enforcement where warranted.

8. Your content and uploaded documents

You are solely responsible for the content your team enters and uploads. We do not pre-screen it. We may, but are not obliged to, remove content that violates these terms or that we are legally required to remove, and we will tell the organization’s supervisors when we do so unless prevented by law.

Uploaded Safety Data Sheets are restricted to PDF format and 25 MB. Uploading a replacement permanently overwrites the previous file; no earlier version is retained, and the overwrite cannot be undone. Export or archive your own copies if you need a version history for compliance purposes.

9. Professional judgment and safety

ChemLevel is decision support. It is not a safety system, an alarm system, a monitoring system, or a substitute for the judgment of qualified operators.

Forecasts, reorder recommendations, order-by dates, order quantities, cylinder swap predictions, and usage anomaly flags are calculated estimates derived entirely from the readings your team enters. They are only as good as that input. A missed round, a mistyped weight, a swapped cylinder that was not logged, or a change in plant operating conditions will all move the numbers, and the forecast becomes meaningfully reliable only after enough history has accumulated.

You and your organization remain solely responsible for chemical handling, storage, dosing decisions, feed rates, personal protective equipment, emergency response, and compliance with every regulation applicable to your facility. Specifically:

• Verify physically before acting. Confirm an actual tank level, cylinder weight, or scale reading before ordering, changing a feed rate, or concluding that supply is adequate.
• Never rely on ChemLevel as the sole basis for a safety-critical decision, including any decision involving chlorine gas, sulfur dioxide, anhydrous ammonia, or any other compressed or acutely hazardous gas.
• Do not rely on ChemLevel as a run-out alarm. It cannot detect a leak, a failed pump, a stuck valve, a miscalibrated scale, or an empty cylinder, and it will not know about any of them until someone records a reading.
• Keep your own required records. ChemLevel is not certified as a regulatory record-keeping system for any jurisdiction, and you remain responsible for the records your primacy agency requires.

10. Safety Data Sheets

ChemLevel is a place to keep Safety Data Sheets. It is not a source of them, and we do not supply, author, verify, review, or update any sheet.

A sheet reached through the Service is whatever your organization uploaded to it. It remains your responsibility to obtain the current supplier-issued Safety Data Sheet for every product actually on your site, to replace it whenever the supplier reissues, and to make it available to your personnel and to emergency responders as the law requires. Nothing in the Service relieves you of any obligation under the OSHA Hazard Communication Standard or any equivalent regulation.

The demo includes generated example sheets that are not real Safety Data Sheets. They exist to show the feature, they are stamped as samples on every page, and they must never be used for emergency response, training, hazard assessment, or regulatory compliance.

11. Offline use, syncing, and notifications

ChemLevel works offline by keeping a copy of your organization’s data on the device and queueing changes until a connection returns. This means what you see on a given device may be out of date, and changes made on two devices while offline may need to be reconciled when they sync. Treat the device in your hand as a possibly stale copy, particularly when acting on a number.

Reorder and stale-reading notifications are generated on your own device from data already stored there. They depend on the operating system or browser delivering them, on the permission being granted, and on the device having current data. They may be delayed, suppressed by the platform, or not delivered at all, and there is no server-side push that can wake a closed application. Do not rely on ChemLevel notifications as a primary or sole alerting mechanism for anything consequential.

12. Intellectual property

ChemLevel, including its software, forecasting methods, interface, design, documentation, and branding, is owned by us and protected by intellectual property law. Subject to these terms and payment of applicable fees, we grant your organization a limited, non-exclusive, non-transferable, revocable license to access and use the Service for its own internal business purposes for the term of the subscription. All rights not expressly granted are reserved. These terms grant no right to our trademarks or branding beyond what is needed to use the Service as intended.

13. Feedback

We welcome suggestions, and we frequently build them. If you send us feedback, ideas, or feature requests, you grant us an unrestricted, perpetual, irrevocable, royalty-free right to use and implement them in any way, without obligation or compensation to you. You are not required to send us feedback, and nothing you send is treated as your confidential information unless we agree otherwise in writing.

14. Third-party services

The Service depends on third parties — hosting, database and file storage, payment processing, and email delivery — and links to sites we do not control. When you choose to email an order, ChemLevel composes a message and hands it to your own email client; you send it, to a vendor you chose, and we are not a party to that communication or to any resulting purchase, contract, delivery, or dispute with your supplier. We are not responsible for third-party services or content, and your use of them is governed by their terms.

15. Availability and changes to the service

We aim to keep the Service available and to give notice of planned maintenance where practical, but we do not guarantee uninterrupted or error-free operation, and no service level agreement applies unless we have signed one with your organization. We may add, change, or remove features, and we may modify or discontinue the Service. If we discontinue the Service or materially reduce functionality your organization depends on, we will give reasonable advance notice and a reasonable opportunity to export your data.

16. Suspension, termination, and your data

You may stop using the Service at any time. Leaving an organization, deleting your own login, and closing the organization are all available in the app under Settings › Leaving ChemLevel; deleting a login can also be done at chemlevel.com/delete-account without installing anything. We may suspend or terminate access for a material breach of these terms, for non-payment, to protect the Service or its users, or if required by law. Where practical and lawful, we will give notice and an opportunity to cure first.

When a trial expires or a subscription is canceled or terminated, the organization’s data is retained for 30 days so it can be recovered if you resubscribe, and is then deleted automatically, including any uploaded Safety Data Sheets. We email the organization’s supervisors and account administrators before that deadline. Export anything you need before it passes. After deletion we cannot recover your data, except for copies in backups until those age out on their ordinary cycle. Sections that by their nature should survive termination — ownership, disclaimers, limitation of liability, indemnification, dispute resolution, and governing law — do survive it.

17. Disclaimer of warranties

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE.” TO THE FULLEST EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT, AND ANY WARRANTIES ARISING FROM COURSE OF DEALING OR USAGE OF TRADE.

WITHOUT LIMITING THAT, WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, SECURE, OR ERROR-FREE; THAT ANY FORECAST, REORDER RECOMMENDATION, ORDER QUANTITY, SWAP PREDICTION, OR ANOMALY FLAG WILL BE ACCURATE OR WILL PREVENT A CHEMICAL FROM RUNNING OUT; THAT NOTIFICATIONS WILL BE DELIVERED; OR THAT ANY DOCUMENT STORED IN THE SERVICE IS CURRENT, ACCURATE, OR COMPLETE. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF CERTAIN WARRANTIES, SO SOME OF THESE EXCLUSIONS MAY NOT APPLY TO YOU.

18. Limitation of liability

TO THE FULLEST EXTENT PERMITTED BY LAW, NEITHER CHEMLEVEL NOR ITS OFFICERS, EMPLOYEES, OR SUPPLIERS WILL BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, LOST REVENUE, LOST OR CORRUPTED DATA, BUSINESS INTERRUPTION, REGULATORY PENALTIES, REMEDIATION COSTS, OR PROCUREMENT OF SUBSTITUTE SERVICES, ARISING OUT OF OR RELATING TO THE SERVICE, WHETHER IN CONTRACT, TORT, OR ANY OTHER THEORY, AND EVEN IF ADVISED OF THE POSSIBILITY.

OUR TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE FEES YOUR ORGANIZATION PAID US IN THE TWELVE MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR (B) ONE HUNDRED US DOLLARS.

THESE LIMITS APPLY EVEN IF A REMEDY FAILS OF ITS ESSENTIAL PURPOSE. THEY DO NOT APPLY TO LIABILITY THAT CANNOT BE LIMITED BY LAW, INCLUDING LIABILITY FOR DEATH OR PERSONAL INJURY CAUSED BY OUR NEGLIGENCE, FOR FRAUD, OR FOR WILLFUL MISCONDUCT. SOME JURISDICTIONS DO NOT ALLOW CERTAIN LIMITATIONS, SO SOME OF THESE MAY NOT APPLY TO YOU.

You acknowledge that the fees for the Service reflect this allocation of risk, that ChemLevel is not priced as a safety system, and that you retain responsibility for the physical verification and independent safeguards described in Section 9.

19. Indemnification

You will defend, indemnify, and hold harmless ChemLevel and its officers, employees, and agents from any third-party claim, and any resulting loss, liability, damage, cost, or reasonable attorneys’ fees, arising out of or relating to: your operational data or uploaded documents, including any claim that they infringe a third party’s rights; your use of the Service in breach of these terms or applicable law; a chemical handling, dosing, storage, procurement, or safety decision made by you or your organization; or your failure to hold or provide a current supplier-issued Safety Data Sheet. We will notify you of any such claim, give you control of the defense (subject to our right to participate with our own counsel), and cooperate reasonably at your expense. You may not settle a claim in a way that imposes an obligation on us without our written consent.

20. Force majeure

Neither party is liable for a failure or delay in performance caused by circumstances beyond its reasonable control, including acts of God, natural disaster, fire, flood, epidemic, war, terrorism, civil unrest, labor dispute, government action, failure of the public internet or of a utility, or the failure or unavailability of a third-party hosting, storage, payment, or email provider. This does not excuse an obligation to pay amounts already due.

21. Dispute resolution and arbitration

Please read this section carefully. It affects how disputes between us are resolved.

Informal resolution first. Before starting a formal proceeding, you agree to contact us at info@chemlevel.com with a description of the dispute and the relief sought, and to give us 30 days to resolve it. Most problems are solved this way.

Binding arbitration. If we cannot resolve a dispute informally, you and ChemLevel agree that any dispute arising out of or relating to these terms or the Service will be resolved by final and binding arbitration administered by [ARBITRATION PROVIDER, e.g. the American Arbitration Association] under its then-current commercial arbitration rules, before a single arbitrator, seated in Houston, Texas. The arbitrator may award the same individual relief a court could, and judgment on the award may be entered in any court of competent jurisdiction.

Exceptions. Either party may bring an individual claim in small claims court, and either party may seek injunctive or equitable relief in court to protect its intellectual property or confidential information.

Class action waiver. DISPUTES WILL BE ARBITRATED ONLY ON AN INDIVIDUAL BASIS. YOU AND CHEMLEVEL WAIVE ANY RIGHT TO BRING OR PARTICIPATE IN A CLASS, COLLECTIVE, CONSOLIDATED, OR REPRESENTATIVE ACTION, AND THE ARBITRATOR MAY NOT CONSOLIDATE CLAIMS OR PRESIDE OVER ANY FORM OF REPRESENTATIVE PROCEEDING. If this waiver is found unenforceable as to a particular claim, that claim will proceed in court and the remainder of this section will still apply.

Jury trial waiver. To the extent any dispute proceeds in court rather than arbitration, you and ChemLevel each waive any right to a jury trial.

Opting out. You may opt out of this arbitration and class waiver section by emailing info@chemlevel.com with your name, organization, and a statement that you opt out, within 30 days of first accepting these terms. Opting out does not affect any other part of these terms.

This section does not apply to the extent applicable law prohibits it, including where a party is a public entity that cannot agree to arbitrate.

22. Governing law and venue

These terms are governed by the laws of the State of Texas, United States, without regard to conflict of law rules, and by the Federal Arbitration Act as to Section 21. Where a dispute proceeds in court under Section 21, you and ChemLevel consent to the exclusive jurisdiction and venue of the state and federal courts located in Harris County, Texas. The United Nations Convention on Contracts for the International Sale of Goods does not apply. If you are a public entity, nothing here waives any right or immunity you cannot waive by law.

23. Changes to these terms

We may update these terms as the Service or the law changes. We will revise the “Last updated” date above, and for material changes we will give active customers reasonable advance notice by email or in the application before they take effect. Continuing to use the Service after a change takes effect means you accept the updated terms. If you do not accept them, stop using the Service and contact us to close your account; Section 16 governs what happens to your data.

24. General

• Entire agreement. These terms and the Privacy Policy are the entire agreement between you and ChemLevel about the Service, superseding prior discussions, unless a signed agreement with your organization says otherwise.
• Severability. If a provision is held unenforceable, it is modified to the minimum extent necessary or severed, and the rest remains in effect.
• No waiver. Not enforcing a provision is not a waiver of the right to enforce it later.
• Assignment. You may not assign these terms without our written consent, except to a successor to your business. We may assign them in connection with a merger, acquisition, or sale of assets.
• No third-party beneficiaries. These terms create no rights for anyone other than you and ChemLevel.
• Notices. We may give notice by email to the address on your account or through the Service. Notices to us go to info@chemlevel.com.
• Relationship. Nothing here creates a partnership, joint venture, employment, or agency relationship.
• Export and sanctions. You represent that you are not subject to sanctions or located in an embargoed jurisdiction, and you agree to comply with applicable export control laws.
• Government use. If you are a US government entity, the Service is “commercial computer software” and any use, duplication, or disclosure is subject to the restrictions in these terms.
