Terms

Last updated: November 14, 2026

These terms cover Part 107 Test Practice at part-107.osidius.ai (“the product”). The product is sold and run by Havelaar US, LLC, a Delaware limited liability company (“we”, “us”, “our”). By buying or using the product you agree to these terms. If you do not agree, please do not use it.

What we sell

90 days of access to one bank of original practice questions for the FAA's remote pilot knowledge test (Unmanned Aircraft General – Small, the test for a remote pilot certificate under 14 CFR Part 107), with an explanation for every choice and a quote from the regulation or FAA publication it rests on for every answer. It is education for exam preparation, not legal advice and not flight instruction, and it is not affiliated with or endorsed by the Federal Aviation Administration or by PSI.

Access starts as soon as your payment goes through: we email you a link to the full bank, and the page after checkout shows the same link. The link is your key: anyone who has it can open the bank, so keep it to yourself. Access ends 90 days after your payment, or when the payment is refunded. Nothing renews.

Who can buy

We sell only to customers in the United States. Our checkout does not start for a visitor whose connection comes from elsewhere. If the billing address given at checkout is elsewhere, we refund the payment in full at once, cancel any subscription it started, and do not deliver the product. You must be at least 18 years old, or the age of majority where you live if that is higher, to buy. Our products are not meant for children under 13.

Prices, taxes and renewal

• Part 107 remote pilot knowledge test practice bank, 90 days: USD 69.00, paid once.

Prices are in US dollars. Where sales tax is due, it is added at checkout. Before you pay, the checkout shows the full amount, and what renews and when.

Payments are handled by Stripe. We never see or store your full card number.

Refunds

If you ask within 30 days of a payment, a first purchase or a renewal, we refund that payment in full, without asking why. Our refund policy says how.

AI agents

Havelaar US, LLC runs Part 107 Test Practice largely with AI agents. Replies to your messages are written by an AI agent of Havelaar US, LLC, and say so. Parts of the product are written by an AI agent of Havelaar US, LLC: the practice questions and their explanations. AI can make mistakes. Check what matters to you, and tell us when something is wrong.

What you put in, and what is ours

What you put into the product stays yours. You allow us to store and process it only to provide the product to you, as our privacy policy describes.

The product itself, including its software, text, design and name, belongs to Havelaar US, LLC. Buying it gives you the right to use it as described under “What we sell”, for as long as it says, not ownership of it.

Using it fairly

Use the product only lawfully. Do not:

• overload, disable or damage it or the systems it runs on, or get around its limits;
• try to get into parts of it, accounts or data that are not yours;
• copy it, extract its data in bulk, or resell it as your own without our written consent.

If you break these terms, we may suspend or end your access.

If we change or stop the product

We may change the product as we improve it. If we stop offering it, we stop all future charges, tell you by email, and either keep it working until the end of the period you paid for or refund the part of your payment that covers the time left. What you have already downloaded or received stays yours to use under these terms.

No warranties

The product is provided “as is” and “as available”, without warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose and non-infringement. We do not promise that it will be uninterrupted or free of errors.

Limitation of liability

To the fullest extent the law allows, Havelaar US, LLC is not liable for any indirect, incidental, special, consequential or punitive damages arising from your use of the product, and our total liability for any claim is limited to the amount you paid us for the product concerned in the 12 months before the claim. Nothing in these terms limits a right that the law where you live does not allow to be limited.

Governing law

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

Changes to these terms

We may change these terms. We post the new version on this page and update the date above. Changes apply from the date shown; continuing to use the product after that date means you accept them.
