Terms of Service
Last updated: September 5, 2026
1. Who we are and what this agreement covers
InfraDrill ("we", "us", the "Service") is an interview preparation platform for Senior/Principal-level Go, Kubernetes, and AWS engineering roles: a documentation-cited question bank, timed quizzes, spaced-repetition flashcards, progress tracking, and a study plan checklist. These Terms govern your use of the Service at our website and any account you create.
These Terms are a binding agreement between you and Piotr Konopka, a natural person based in Poland. The activity is conducted as działalność nierejestrowana (unregistered activity under Polish law), where the statutory conditions for that form of activity are met. It is not entered in CEIDG, so there is no company registration number to provide. Any tax identifier required by applicable law will be given where required. Consumer-protection laws applicable to traders apply to consumer contracts entered into through the Service. If the activity is registered in the future, these pages will be updated with the applicable registration details.
Operator: Piotr Konopka, Wiosenna 20, 55-100 Trzebnica, Poland.

Purchases are sold by Paddle acting as Merchant of Record; InfraDrill provides the Service itself. When you buy a pass, Paddle is the seller on that transaction and issues your receipt; we supply the Service itself. Paddle's buyer terms apply to the payment, and these Terms apply to your use of the Service.
2. Accounts
You must provide a valid email address and a password of at least 8 characters to register. We do not ask for your name, and there is no field for one. You're responsible for keeping your credentials confidential and for all activity under your account. Tell us promptly if you believe your account has been compromised.
You must be at least 18 years old to create an account. InfraDrill prepares people for Senior and Principal engineering interviews, so it is aimed at those already in professional work. We do not knowingly offer accounts to anyone under 18.
3. What is free, and what a pass unlocks
The way to try InfraDrill without paying is /demo, and it needs no account: a sample of questions with their explanations and sources, a practice quiz that runs in your browser, and two of the coding exercises. Nothing is sent to us and nothing is stored beyond your own browser.
An account does not provide the paid practice features. Creating one is a step in buying a pass — it is how we confirm the address is yours before you pay, and how your pass and your history stay attached to you. An account without an active pass, whether because you have not bought yet or because a pass has run out, can see the catalogue of packs and exercises and read back its own history, and cannot practise: the question bank, quizzes, packs, flashcards, exercises and the study plan checklist all need a pass.
A paid pass (see current pricing at /pricing) is what unlocks the practice itself: browsing the question bank — text, options, explanations and sources — starting and submitting timed quizzes and packs, the spaced-repetition flashcards, the remaining coding exercises with their worked solutions, and ticking off study plan steps.
Paid access is sold as a one-time pass — 30 days, 3 months, or 6 months — not as a subscription. Nothing renews automatically and nothing is charged again when the period ends. There is no recurring payment to cancel: when a pass expires, your account stays and keeps all of your history — your past quizzes, answers and progress stay readable, and what stops is starting anything new.
Prices are shown at /pricing and the final price, including any applicable taxes, is shown by Paddle before you complete the purchase. Paddle collects and remits those taxes as Merchant of Record. We may change prices at any time; a change never affects a pass you have already bought.
Access begins as soon as payment completes. Refunds and statutory withdrawal requests are handled under our Refund Policy, which forms part of these Terms.
3a. Your right to withdraw
If you are a consumer in the EU, you have 14 days from the day you buy a pass to withdraw from the contract without giving a reason, under the Consumer Rights Directive as implemented in Polish law. Consumers elsewhere, including the UK, have whatever equivalent right their own law gives them — we do not attempt to summarise it here, and Paddle applies it as the seller.
A pass gives you a digital service supplied over the period it covers — an account that keeps your quizzes, your progress and your place — and, as part of it, digital content: the questions, their explanations and the coding exercises. Which statutory rules apply to a particular part of it follows from what that part is and from the law, and we do not try to settle that here.
What we do state, because it is the part that matters to you: a 30-day, 3-month or 12-month pass is plainly not fully performed on the day it starts, so asking us to start immediately does not take your withdrawal right away.
We do ask you at checkout to request that we begin straight away, because otherwise we would have to make you wait 14 days for access you have paid for. We ask for it explicitly and never infer it from the act of purchasing. If you then withdraw within the 14 days, the law entitles us to a proportionate amount for the service supplied up to the moment you withdraw — measured against the access you were provided for that part of the period, not against how much of it you happened to use — and the rest comes back to you.
Paddle applies this right as the seller on your purchase, so you do not need our agreement to use it. Full detail is in our Refund Policy.
To withdraw, contact Paddle — the seller on your purchase — at paddle.net or through the support link on your receipt, using any clear statement to that effect. Paddle refunds to the original payment method. You are welcome to tell us as well at support@infradrill.dev, but a statutory withdrawal is Paddle's to process, because Paddle took the payment and Paddle returns it.
4. Content, accuracy, and what the Service is not
Every question is meant to cite a real, checkable source (official documentation, a book, or another relevant technical reference) and is labeled Verified or Pending review in the product — pending-review questions have been generated and cross-checked but not yet manually confirmed by a person. We work to keep the bank accurate, but interview questions, technology documentation, and best practices change, and we don't guarantee completeness, currentness, or fitness for any specific interview, employer, or hiring process. The Service is a practice tool, not professional, career, or certification advice, and using it is not a guarantee of interview or job-search success.
4a. Digital-service conformity and complaints
InfraDrill is a digital service, and we owe you a service that matches what these pages describe — in what it does, how it behaves, and that it keeps working for the period you paid for. The disclaimers in section 4 are about the accuracy of interview content and the outcomes you might hope for; they do not, and cannot, remove your statutory rights when the Service itself fails to conform to this contract.
If something is wrong — the Service is unavailable, a feature does not work, or it simply is not what we described — write to support@infradrill.dev and tell us what happened and, if you can, when. You do not need a particular form of words and you do not need to cite a statute.
We reply within 14 days, on a durable medium — normally by email. Polish law gives a trader that long to answer a consumer complaint and treats one left unanswered within it as accepted, so the period is named here rather than left to "as the law requires". Where a complaint is well founded, the remedies available to you are those provided by consumer law for the non-conformity of a digital service, and nothing here asks you to give them up or to come to us first.
5. Intellectual property
The platform, its design, and the compiled/curated question bank are owned by us or our licensors. Question content is original material — written and organized by us, citing external sources rather than copying them verbatim (we specifically avoid reproducing exam-dump content word-for-word). You may use the Service for your own personal interview preparation. You may not scrape, bulk-export, republish, resell, or otherwise redistribute the question bank or platform content, or attempt to circumvent any access or entitlement controls.
6. Acceptable use
- No automated scraping, bulk downloading, or reverse-engineering the question bank.
- No sharing a single account across multiple people, or reselling access.
- No attempting to bypass rate limits, authentication, or entitlement checks.
- No uploading unlawful, infringing, or abusive content anywhere the product accepts input.
We may suspend or terminate accounts that violate these terms.
7. Termination
You may stop using the Service and ask us to delete your account at any time (see our Privacy Policy for how). We may suspend or terminate accounts for violation of these terms, non-payment once paid plans exist, or to comply with legal obligations.
8. Disclaimers and limitation of liability
The Service is provided "as is" without warranties of any kind, to the fullest extent permitted by law. We are not liable for indirect, incidental, or consequential damages arising from your use of the Service, including any interview or employment outcome, to the fullest extent permitted by applicable law. Nothing in these Terms limits liability that cannot be excluded under mandatory Polish or EU consumer-protection law.
9. Changes to these Terms
We publish the current version of these Terms here, with the date it last changed. Where the law requires us to notify you of a material change, or gives you a right to end your agreement because of one, we will give that notice on a durable medium — normally by email to the address on your account.
Changes to the Service itself, while your pass is running. We may change the Service where that is reasonably necessary for a justified reason: keeping it secure, keeping it lawful, maintaining compatibility with the platforms it runs on, fixing defects, and maintaining or improving the functionality it already provides. If a change would significantly and negatively affect your access to the Service or your use of it, we will tell you in advance on a durable medium and tell you what you may do about it, including any right to end the agreement that the law gives you in that situation. A change will never cost you more during a pass you have already bought, and never reduces rights the law gives you.
The question bank and the exercises change over time: we add material, correct it, replace it and retire it. That is ordinary maintenance of the Service and is what the paragraph above permits. Removing a substantial part of what your pass was described as covering is not, and we do not treat it as such.
10. Governing law
These Terms are governed by Polish law. Nothing here limits any mandatory consumer protections you're entitled to under the law of your country of residence if you're an EU consumer.
