MyoBooks End-User License Agreement (self-host)

Effective: 26 August 2026
Version: 1.1
MyoBooks LLC, an ordinary Arizona limited liability company (ACC Business ID 25111625), 175 Hohokam Drive, Sedona, AZ 86336.

These terms are between you and MyoBooks LLC ("Company"). They license the MyoBooks software you install and run. They do not sell a hosted ledger, a CPA, a filing, or tax advice. The Subscription Terms cover what you pay for. This EULA plus the Subscription Terms are the agreement for the software license.

1. Who this is for

You install MyoBooks on a machine or host you control. If you accept for an organization, you say you can bind it. Entity tags (personal, sole prop, LLC, S-Corp) are your labels, not legal formation or tax advice.

2. What Company sells vs what you host

Company sells a subscription: billing, entitlement, updates during a paid term, paid features in the then-current plan, and support as then described.

The app is self-hosted. You run it. You hold the books. Company does not host ledgers, operate multi-tenant SaaS books, or do payroll. Bank connect is optional: you put your own Plaid and/or Teller keys on your instance, same as Kraken keys. Company does not run a bank-link and does not operate a Plaid or Teller webhook. Tokens and transaction payloads stay on your instance. File drop stays. Optional Kraken for crypto uses keys that stay on your instance.

3. License grant

Company grants you a limited, non-exclusive, non-transferable license to install and run the MyoBooks software on devices and hosts you control, for your own books.

That grant has two layers:

  1. Open, read, and export. For a copy you have installed, you may open the instance, read the books, and export your data. This layer does not die when the subscription lapses. We do not brick the instance. We do not lock you out of your own files to collect a renewal.
  2. Updates and paid features. While the subscription is in good standing (or during a separately granted evaluation), you may download updates and use paid features in the then-current plan. When the subscription lapses, this layer stops.

The license is for your own use. It is not a right to resell the app, sublicense it, or run it as a public hosted-books service for other people.

4. What you own

You own your data and ledger files on your machine or host (books, imported bank files, categories, tax assumptions you set, local Kraken, Plaid, and Teller keys you configure). Company does not get a license to those books and does not receive or store ledgers, bank files, Kraken keys, or transaction data.

5. What Company owns

Company (and its licensors) own the software, brand, and docs. You get a license, not the code or the name. Open-source components, if any, stay under their own licenses.

6. Restrictions

You may not:

  1. Reverse engineer the software beyond what applicable law allows.
  2. Resell, rent, or sublicense the app.
  3. Represent MyoBooks as a filing service, a hosted ledger, a CPA, or a payroll product.
  4. Use the software to provide a competing hosted-books service to third parties.
  5. Share one subscription as a public hosted service for other people (see the Subscription Terms).
  6. Remove notices of ownership on the software.

7. Self-host risk

You are responsible for backups, who can access your instance, updates you apply, and the machine, OS, network, and host you run on.

If your disk dies, your host is misconfigured, or someone you let in reads the books, that is on you. Company is not a processor of the ledger and cannot restore books it does not hold.

8. If the subscription lapses

If the subscription lapses or you cancel:

  • the instance you already have still opens;
  • you can still read the books;
  • you can still export your data;
  • updates stop;
  • paid features stop;
  • we do not brick the instance.

We do not require an active subscription merely to open books you already keep on your machine. Section 3(1) survives lapse.

9. Tax and accounting disclaimer

Tax output is estimates only. That includes federal cash-basis estimates, pluggable state estimates, and 1040-ES-style estimates.

Estimates are not a tax filing, e-file, tax advice, legal advice, or the work of a CPA or attorney.

You can override categories and tax assumptions. You must verify numbers. You remain responsible for filings and tax. Using the app does not make Company or Ryan Nichols your CPA, attorney, or fiduciary. Selling this subscription does not make Company your law firm, CPA firm, or real-estate broker on the books.

10. Ask Myo (optional assistant)

Ask Myo is optional. You can keep books without it.

Ask Myo runs on a key you configure. If you turn it on, prompts may leave your machine and go to a model provider you choose, with your key or your endpoint. That vendor, data, and risk are yours.

Company does not proxy books. Company does not send your ledger through our servers to a model. You point Ask Myo at a provider you choose, with your own key — not a Company pipe.

Ask Myo is not tax, legal, or accounting advice. Estimates still require human review.

11. Term, lapse, and breach

This license starts when you install or first run the Software.

Lapse or cancel is section 8. Open, read, and export stay. Updates and paid features stop. We do not brick the instance.

Breach of these terms (including section 6) is different. Company may end the license, including the right to run the Software. That is for breach, not for a lapsed card.

When any license ends, you keep your local data. Company does not delete books it never held.

12. No warranty (as-is)

The software is provided as is and as available. Company does not warrant that estimates are correct, that the app is error-free, or that it will meet a filing deadline.

To the fullest extent allowed by law, Company disclaims implied warranties, including merchantability, fitness for a particular purpose, and non-infringement.

Some states do not allow certain warranty exclusions. If those rules apply to you, some of this section may not apply, and you may have rights the law does not let us take away.

13. Limitation of liability

To the fullest extent allowed by law:

  • Company is not liable for indirect, incidental, special, consequential, or punitive damages, or for lost profits, lost data, or the cost of substitute software, even if told they were possible.
  • Company's total liability for claims arising out of the software or these terms is capped at the fees you paid Company for the MyoBooks subscription in the 12 months before the claim.

This cap does not apply to liability the law does not let us limit.

Some states do not allow exclusion of incidental or consequential damages, or a cap on certain claims. If those rules apply to you, some of this section may not apply.

Company does not host your ledger. Local data loss or a wrong estimate is not a hosted-service claim.

14. Governing law and venue

These terms are governed by the laws of the State of Arizona, without regard to conflict-of-law rules.

Governing law is Arizona. Exclusive venue: the state courts in Yavapai County, Arizona.

These terms plus the Subscription Terms are the agreement for the software license. On fees, billing, or cancellation, the Subscription Terms control. On the license grant, lapse, ownership of the software, or self-host risk, this EULA controls.
