Terms of Service

These Terms of Service (the "Terms") govern access to and use of Alkali Engineering, Inc.'s software and services, including the Alkali web application and PDF annotation and estimation tools (collectively, the "Service"). If you are using the Service on behalf of a company or other entity, you represent that you have authority to bind that entity, and "Customer" refers to that entity.

1. Accounts and access

You are responsible for safeguarding your credentials and for all activity under your account.
You must provide accurate account information and keep it current.
You may not share accounts except as permitted by your subscription plan.

2. Customer Content (including annotations)

"Customer Content" means files, drawings, PDFs, project data, and any markups/notes/annotations that you or your users upload, submit, or create in the Service.

Ownership: Customer retains all right, title, and interest in Customer Content.
License to operate the Service: Customer grants Alkali a non-exclusive, worldwide license to host, store, reproduce, process, transmit, and display Customer Content solely to provide, secure, and maintain the Service and to perform support and troubleshooting.
Product improvement (designed to be non-scary): Customer also grants Alkali permission to use Customer Content-derived signals (including annotations and metadata) to improve the Service, but only in aggregated and/or de-identified form. We do not publish or sell your Customer Content, and we do not use your confidential drawings as marketing examples without your explicit permission.
Opt-out: If you want to opt out of product-improvement use, contact us at founders@alkali-eng.com. Opt-out does not affect our ability to process Customer Content to provide the Service.

3. Confidentiality

We treat Customer Content as confidential and will not disclose it to third parties except (a) to subprocessors that help us run the Service (e.g., hosting, databases, analytics, support tools) under appropriate confidentiality obligations, (b) as directed by Customer (e.g., sharing features you use), or (c) as required by law.

4. Acceptable use

You agree not to:

Use the Service for unlawful activities.
Attempt to access accounts, data, or systems you are not authorized to access.
Interfere with or disrupt the Service, including by introducing malware.
Reverse engineer the Service except where prohibited by law.

5. Fees and subscriptions

Fees, billing cadence, seat counts, and any trial terms are as stated in your order form, invoice, checkout flow, or subscription page. Unless otherwise stated, subscriptions renew automatically until cancelled.

6. Intellectual property

Alkali retains all rights in the Service, including software, models, and documentation, excluding Customer Content. If you provide suggestions or feedback, you grant Alkali a right to use it without restriction or compensation.

7. Disclaimers

The Service is provided "as is" and "as available." Estimates, measurements, AI detections, and outputs are intended to assist workflows and may require review. Customer is responsible for verifying outputs for their use case.

8. Limitation of liability

To the maximum extent permitted by law, Alkali will not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, revenue, data, or goodwill. Alkali's total liability for all claims relating to the Service will not exceed the amounts paid by Customer to Alkali for the Service in the 12 months preceding the event giving rise to the claim.

9. Termination

You may stop using the Service at any time. We may suspend or terminate access if you materially breach these Terms. Upon termination, your right to use the Service ends. Data retention/deletion is described in the Privacy Policy.

10. Changes

We may update these Terms from time to time. If changes are material, we will provide notice via the Service or email. Continued use after the effective date of an updated Terms constitutes acceptance.
