Terms of Use

Effective and last updated: October 8, 2026

1. About these terms

These terms are an agreement between you and Angry Pixie Electronics LLC, a Minnesota limited liability company (“we”, “us”). They cover the Holarch website at holarch.app and the Holarch application at app.holarch.app (together, the “Service”).

By creating an account or using the Service, you agree to these terms and to the Privacy Policy. If you use the Service for a school, company or other organization, you confirm that you may accept these terms for it, and “you” includes that organization.

These terms do not cover copies of Holarch that an organization runs in its own environment. A separate agreement covers those.

2. Eligibility and accounts

You must be at least 13 years old to use the Service.
If you are under 18, you may use the Service only with the consent of a parent or guardian, or as part of a class or program run by your school.
Accounts are currently by invitation only.
Give accurate information when you create your account, and keep it up to date.
Keep your password secret. You are responsible for what happens in your account. An account is for one person; do not share it.
If you think someone else has used your account, change your password, end your other sessions on the account page, and contact us.

3. Data you must not store

The Service is not for controlled unclassified information (CUI), export-controlled information (including data controlled under ITAR or EAR), or classified information. You acknowledge this when you create your account.

Do not upload, enter or share such information in the Service, and do not send it to an AI provider through the Service.
The Service has no FedRAMP or other government authorization, and it is not designed to meet the security requirements for such information.
If a project is marked as CUI, export controlled or classified, the Service shows a warning and blocks AI features for that project. These checks are an aid only. You remain responsible for what you store.
If we learn that such information is in the Service, we may restrict access to it, remove it or suspend the account, and we may notify the account owner.

Organizations that need to work with regulated information can run Holarch in their own authorized environment. Contact us about that option.

4. Your content

“Your content” means the projects, models, documents, diagrams, files and other material you put into the Service.

You keep ownership of your content. We claim no ownership of it.
You give us a limited, worldwide, non-exclusive license to host, store, copy, process, transmit and display your content only as needed to run, secure, back up and support the Service for you. This includes showing it to people you share a project with, and sending it to an AI provider when you start an AI feature (section 6).
This license ends when your content is deleted from the Service, except for copies in backups until they expire (section 10).
You confirm that you have the rights needed to put your content in the Service, and that it does not break these terms or the law.
We do not use your content to train AI models, and we do not sell it.
If you send us suggestions or feedback, we may use them without obligation to you.

A project owner decides who can open a project and with which role (owner, editor or viewer). People you invite see the project’s content according to their role. You are responsible for whom you share with. Content that others add to a shared project remains theirs.

6. AI features

AI features use an API key you (or your organization’s administrator) add for a provider you choose: currently Anthropic, OpenAI, Google or Microsoft Azure OpenAI. We do not supply AI access.
When you start an AI feature, the content needed for that request is sent to that provider. The provider handles it under its own terms and your agreement with it. Charges for that use are between you and the provider.
We store keys encrypted and use a key only for AI requests made from the account or organization it belongs to.
AI output can be wrong or incomplete. The Service shows proposed changes for your review before they apply. You are responsible for checking and using the output.

7. Acceptable use

Do not use the Service to:

break any law, or infringe anyone’s intellectual property, privacy or other rights;
store or share the information listed in section 3;
upload malware, or content meant to attack the Service or other users;
access accounts, projects or data you are not allowed to access, or probe, scan or test the Service’s security without our written permission;
overload or disrupt the Service, get around rate limits, storage limits or other technical limits, or access it by automated means other than the features we provide;
harass, threaten or harm others, or share unlawful, hateful or sexually explicit material;
resell, rent or provide the Service to others as a hosted service without our written permission;
copy or reverse engineer the Service, except where the law allows it despite this restriction.

If you find a security problem, report it through the contact form and do not access other users’ data.

8. Academic use

Students and instructors can use the Service free for coursework and teaching. Academic accounts are not for commercial work or funded-contract work.
When a school or instructor uses the Service for a class, student work in the Service can be an education record under the U.S. Family Educational Rights and Privacy Act (FERPA). In that case we act as a service provider to the school: we use those records only to provide the Service to the school and its students, under the school’s direction, and we disclose them only as these terms and the Privacy Policy allow.
The school remains responsible for its own obligations under FERPA and other student-privacy laws, including any notices and consents.

9. Plans, fees and payment

Free and academic use. The Free plan costs nothing. AI features on the Free plan need your own AI key.
Paid plans. The Individual and Team plans are subscriptions billed monthly or yearly at the prices shown on the Pricing page when you subscribe. Team plans are billed per seat. Prices are in US dollars; taxes are added at checkout where they apply.
Merchant of Record. Our order process is conducted by our online reseller Paddle.com. Paddle.com is the Merchant of Record for all our orders. Paddle handles payment, sales tax and VAT, invoicing, billing questions and refunds, under the Paddle Checkout Buyer Terms.
Free trial. A paid plan can start with a 14-day free trial. No payment card is needed and nothing is charged during the trial. If you do not subscribe by the end of the trial, your account moves to the Free plan.
Renewal and cancellation. Subscriptions renew automatically at the end of each billing period until you cancel. You can cancel at any time in the billing portal; your plan continues until the end of the period you paid for.
Refunds. Refunds follow our Refund Policy.
Included AI usage. Paid plans include a monthly number of AI tokens, shown on the Pricing page. Tokens reset each month and do not carry over. When they are used up, AI features use your own key if you added one, or stop until the next month. We may apply additional fair-use limits to prevent abuse.
Changes to prices. We will give at least 30 days’ notice before a price change applies to your subscription. The change takes effect at your next renewal after the notice period.
Downgrades. If a paid plan ends, your projects are kept. Content above the limits of the Free plan becomes read-only until you are within the limits again; it is not deleted.

10. Export, deletion and backups

Export: you can export any project you can open as a project file (JSON) at any time.
Delete a project: a deleted project goes to the Trash. The owner can restore it for 30 days. After that it is deleted permanently.
Delete your account: you can delete your account on the account page. Projects that only you belong to are deleted at once, without going to the Trash. For a shared project you own, transfer ownership or remove the other members first.
Files: uploaded files that no project uses any more are deleted 30 days after their last use.
Backups: deleted data can remain in backups until they expire, within 30 days. We restore from backups only to recover the Service from a failure.
Logs: kept as described in the Privacy Policy.

Export anything you want to keep before you delete it. Deleted data cannot be recovered after these periods.

11. Suspension and termination

You can stop using the Service and delete your account at any time.
We may suspend or close your account, or remove content, if you break these terms, if your use puts the Service, other users or us at risk, or if the law requires it. Where it is practical and lawful, we will tell you first and give you a chance to fix the problem or export your content. If an administrator closes an account, it is kept for 30 days and can be restored during that time; after that it and the projects it owns alone are deleted.
We may change or stop offering parts of the Service. If we stop offering the hosted Service as a whole, we will give at least 30 days’ notice so you can export your content.
Sections 4, 10 and 14 to 20 continue to apply after your account ends.

12. Security and incident notification

We protect the Service with the measures described on the Security page. No online service is completely secure, and we cannot guarantee that your content will never be accessed without permission.

If we learn of a security incident in which your account data or content was accessed, disclosed or changed without permission, we will notify affected users by email without undue delay, and within any deadline the law sets. The notice will say what happened, which data was involved, what we are doing about it, and what you can do.

13. Copyright complaints

We respond to notices of claimed copyright infringement under the U.S. Digital Millennium Copyright Act (DMCA). To report content in the Service that you believe infringes your copyright, send a notice through the contact form (topic “Other”) or to our designated agent: Paul Warmuth, Angry Pixie Electronics LLC, PO Box 309, Deerwood, MN 56444. The notice must include:

your physical or electronic signature;
a description of the copyrighted work;
a description of the content you claim infringes it, with enough detail for us to find it;
your name, address, telephone number and email address;
a statement that you believe in good faith that the use is not authorized by the copyright owner, its agent or the law; and
a statement, under penalty of perjury, that the information in the notice is accurate and that you are the copyright owner or authorized to act for the owner.

If we remove content because of a notice, we will tell the user who posted it. That user may send a counter-notice with the information required by 17 U.S.C. § 512(g). In appropriate circumstances, we close the accounts of repeat infringers.

14. Disclaimer

The Service is provided “as is” and “as available”. To the extent the law allows, we disclaim all warranties, express or implied, including warranties of merchantability, fitness for a particular purpose, title and non-infringement. We do not promise that the Service will be uninterrupted, error-free or free of data loss, or that results from the Service, including analyses, simulations and AI output, are correct. Keep your own exports of important work.

15. Limitation of liability

To the extent the law allows:

we are not liable for indirect, incidental, special, consequential or punitive damages, or for lost profits, revenue, data or goodwill, arising from or related to the Service or these terms, even if we were told they were possible; and
our total liability for all claims arising from or related to the Service or these terms is limited to the greater of the amount you paid us for the Service in the 12 months before the claim, or US$100.

Some places do not allow some of these limits. There, they apply only as far as the law allows.

16. Indemnity

To the extent the law allows, you will defend and indemnify us against claims, damages and costs (including reasonable legal fees) arising from your content, your use of the Service in breach of these terms, or your breach of the law or of anyone else’s rights.

17. Export and sanctions laws

Comply with U.S. and other applicable export-control and sanctions laws when you use the Service. Do not use the Service if you are located in, or ordinarily resident in, a country or region subject to comprehensive U.S. sanctions, or if you are on a U.S. government list of restricted parties.

18. Changes to these terms

We may update these terms. For material changes, we will notify you by email or in the app at least 30 days before they take effect. Other changes take effect when posted here with a new “Last updated” date. If you keep using the Service after a change takes effect, you accept the updated terms. If you do not agree, stop using the Service and delete your account.

19. Governing law and disputes

These terms are governed by the laws of the State of Minnesota and applicable U.S. federal law, without regard to conflict-of-laws rules. Disputes will be resolved in the state or federal courts located in Crow Wing County, Minnesota, and both parties consent to their jurisdiction. This does not take away rights you have under the mandatory consumer-protection laws of the place where you live.

20. General

These terms and the Privacy Policy are the whole agreement between you and us about the Service.
If part of these terms cannot be enforced, the rest stays in effect.
If we do not enforce a part of these terms, we keep the right to enforce it later.
You may not transfer these terms without our consent. We may transfer them to a successor in a merger, acquisition or sale of the Service.
We are not responsible for delays or failures caused by events outside our reasonable control.
