Naxos

Terms of Service

Last updated November 5, 2026

These terms govern your use of Naxos, the microwave path design and line-of-sight service operated by TheseusNet AI ("we", "us"). By creating an account or using Naxos you agree to them. If you use Naxos for a company, you confirm you can bind that company to these terms.

1. What Naxos is, and what it is not

Naxos calculates path profiles, link budgets, availability, interference screens and related outputs from public terrain, lidar, land-cover and FCC licensing data, ITU-R propagation models, and the equipment information you or we supply. Its results are engineering estimates.Public data can be out of date or wrong, especially near towers, buildings and recently changed land, and generic equipment figures are typical values, not any specific product's performance.

Naxos does not replace a licensed engineer's judgment, a site survey, a structural analysis or frequency coordination. You are responsible for verifying any result before relying on it, including before climbing, installing equipment, ordering materials, or filing with the FCC. Never use Naxos as the sole basis for a decision that affects anyone's safety.

2. Accounts

Keep your login secure and don't share it; each seat is for one person. You are responsible for activity under your account. Tell us promptly if you suspect unauthorized use.

3. Plans, trials and billing

  • Trials are free and limited in time and usage. When a trial ends, your workspace becomes read-only until you choose a plan.
  • Crew tools may be offered free during an early-access period, with monthly usage limits. If we start charging for them we will tell you at least 30 days ahead, and you will not be charged unless you choose a paid plan.
  • Paid plans are billed in advance, monthly, annually or for a prepaid three-year term, through our payment processor, Stripe. Plans renew automatically for the same term unless you cancel before renewal.
  • You can cancel at any time from Billing; cancellation takes effect at the end of the period you have paid for.
  • Fees are not refunded for partial periods or unused capacity, except where the law requires it.
  • If a payment fails, you keep full access for a short grace period. After that the workspace becomes read-only until payment goes through. Your data is not deleted because of a failed payment.
  • Plan limits (seats, links, imports, checks) are shown on the Billing page. We may change prices with at least 30 days' notice; changes apply from your next renewal.
  • Prices exclude taxes, which are added where required.

4. Your data

Your designs, sites, equipment files and other content remain yours. You give us permission to store and process them only to run Naxos for you, keep it secure, and support you. We don't sell your data. You can export your designs while your account is active, including when it is read-only. How we handle personal information is described in our Privacy Policy.

You must have the right to upload anything you upload. In particular, vendor radio and antenna files are often licensed by their manufacturers; upload only files you are permitted to use this way.

5. Theseus answers and the crew community

  • Theseus is an AI assistant. Its answers are generated from our reviewed field notes and can still be wrong or incomplete. Treat them like advice from a colleague: check them, and never let them override your site safety plan, your employer's procedures or your RF engineer.
  • Community questions, answers, votes and your handle are visible to every Naxos user. Don't post customer names, site identifiers, credentials, or anything your employer treats as confidential.
  • By posting, or by sending a fix report, you let us show, edit and publish that content in Naxos, including as part of our field notes that Theseus uses, with credit to your handle. We review fix reports before publishing and may decline or edit them.
  • Don't post advice that skips safety steps, harass anyone, or try to game the points and leaderboard. We may remove posts, reset points or suspend accounts that do.
  • Points, ranks and badges are recognition within Naxos. They have no cash value and are not a certification.

6. Acceptable use

Don't:

  • access another workspace's data, or try to get around plan limits, security or authentication;
  • scrape, bulk-download or automate Naxos beyond normal use of its features, or resell access to it;
  • use it to build a competing product, or reverse-engineer it except where the law allows;
  • upload malicious files or content you have no right to use;
  • use it in violation of any law or regulation, including FCC rules.

We may suspend accounts that break these rules or put the service or other customers at risk.

7. Third-party data

Naxos relies on data from third parties, including the USGS 3D Elevation Program, OpenTopography, LANDFIRE, the FCC Universal Licensing System and Antenna Structure Registration, and map tile providers. That data is provided by its owners on their own terms, without any promise of accuracy, completeness or availability.

8. Availability and changes

We work to keep Naxos available and accurate, and we improve its models over time. Improvements can change the results of a design you have already run. We may change or retire features; if we retire something material to a paid plan, we will give reasonable notice.

9. Disclaimer

Naxos is provided "as is" and "as available". To the fullest extent the law allows, we disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose, accuracy and non-infringement. We do not warrant that any result is correct or that a path will perform as calculated.

10. Limitation of liability

To the fullest extent the law allows, we are not liable for indirect, incidental, special, consequential or punitive damages, or for lost profits, revenue, data or equipment, arising from your use of Naxos or reliance on its results. Our total liability for any claim relating to Naxos is limited to the fees you paid us for Naxos in the 12 months before the claim arose.

11. Ending your account

You can stop using Naxos at any time. We may end or suspend accounts that breach these terms. After an account ends, we may delete its data after a reasonable period; export anything you want to keep first.

12. Changes to these terms

We may update these terms. For material changes we will notify account owners in advance, and continued use after the change takes effect means you accept the new terms.
