Privacy Policy

Tile 01 / GDPR

This Privacy Policy explains how CrystalQueryNest ("we", "us") collects, uses, and protects personal data when you visit our website, send us a project brief, or otherwise work with us. It applies in accordance with Regulation (EU) 2016/679 (General Data Protection Regulation — GDPR).

Data Controller

CrystalQueryNest — Kárász utca 11, 6720, Szeged, Hungary

Email: [email protected]

1.1 — Data We Collect

Brief data: the name, work email, company, phone number, budget range, service interest, and project description you type into the contact form. Correspondence data: the contents of emails, call notes, and attachments you send to [email protected]. Technical data: anonymized IP address, browser type, and pages viewed, collected only if you consent to analytics cookies as described in our Cookie Policy. Contract data: billing details, invoices, and payment status for clients who engage our services.

1.2 — Purposes & Legal Bases

We process brief and correspondence data to answer your enquiry and prepare a proposal (Art. 6(1)(b) GDPR — steps prior to a contract) or, where you have asked us to, to perform a signed statement of work (Art. 6(1)(b)). We process contract and billing data to deliver services and meet Hungarian tax and accounting obligations (Art. 6(1)(c)). We use technical data for security, abuse prevention, and — only with your consent — website improvement (Art. 6(1)(a) and Art. 6(1)(f), our legitimate interest in a secure, usable site). We never use your data for automated decision-making or profiling, and we never sell personal data.

1.3 — Processors & International Transfers

We share data only with processors who help us run the business: our EU-hosted email and infrastructure providers, our payment provider Stripe (for invoices you choose to pay online), and — where a project requires it — the cloud vendors named in your statement of work. Each processor acts under a written data-processing agreement. Should a processor outside the European Economic Area be involved, transfers are safeguarded by the European Commission's Standard Contractual Clauses.

1.4 — Retention

Project briefs and pre-contract correspondence are kept for 24 months after our last exchange, then deleted. Client contracts, invoices, and accounting records are retained for 8 years as required by Hungarian tax law. Newsletter or marketing consents (if given) last until you withdraw them. When a retention period ends, data is irreversibly deleted or anonymized.

1.5 — Your Rights

You have the right to access, rectify, erase, restrict, and port your personal data; to object to processing based on legitimate interests; and to withdraw consent at any time without affecting prior lawful processing. To exercise any right, email [email protected] — we respond within one month. You may also lodge a complaint with the Hungarian supervisory authority, NAIH (Nemzeti Adatvédelmi és Információszabadság Hatóság), naih.hu.

Terms of Service

Tile 02 / Engagement

These Terms govern every engagement between CrystalQueryNest (Kárász utca 11, 6720, Szeged, Hungary) and the client named in the applicable statement of work ("SOW"). By signing an SOW or paying an invoice, you accept these Terms.

2.1 — Services & Scope

We deliver data engineering services — pipeline architecture, warehouse builds, transformation modeling, streaming infrastructure, dashboards, audits, and retainers — as described on our service pinboard and fixed in each SOW. Anything outside the agreed scope is handled as a change request with its own price and timeline. Published prices are indicative until confirmed in an SOW.

2.2 — Client Responsibilities

You will provide timely access to systems, credentials, documentation, and a named decision-maker, and you warrant that you have the rights to share any data you hand over for processing. Delays in access or feedback extend delivery timelines day for day. You remain the controller of the data you store in your platforms; we act as your processor where the SOW says so.

2.3 — Fees & Payment

Fixed-scope fees are invoiced according to the SOW milestone schedule, payable within 14 calendar days of the invoice date unless stated otherwise. Retainers are billed monthly in advance. Overdue amounts accrue 4% interest per annum plus reasonable recovery costs. Online payments are processed by Stripe via the Pay link on this site; we never see or store your full card details.

2.4 — Intellectual Property

Upon receipt of full payment, all intellectual property rights in the client-specific deliverables — pipeline code, dbt models, dashboards, and documentation written for your project — transfer to you outright. We retain ownership of our pre-existing frameworks, libraries, and internal tooling, and grant you a perpetual, non-exclusive license to any such components embedded in your deliverables.

2.5 — Confidentiality

Both parties will keep each other's confidential information secret for five years after the engagement ends, except where disclosure is required by law. We may name you as a client in our portfolio only with written permission.

2.6 — Warranty & Liability

Deliverables are warranted to materially conform to the SOW for 30 days after handover; we will correct reported defects within that window. Except as expressly stated, services are provided "as is" without other warranties. To the fullest extent permitted by law, each party's total liability is capped at the fees paid or payable under the relevant SOW in the preceding 12 months, and neither party is liable for indirect or consequential losses. Nothing here limits liability that cannot be limited by law, including for gross negligence or personal injury.

2.7 — Termination & Governing Law

Either party may terminate an SOW for material breach that remains uncured 15 days after written notice; you may also cancel a fixed-scope project at any time under the Refund Policy. These Terms are governed by the laws of Hungary, and the courts of Szeged have exclusive jurisdiction, without prejudice to mandatory consumer protections in your country of residence.

Cookie Policy

Tile 03 / Tracking

This Cookie Policy describes how CrystalQueryNest uses cookies and similar technologies (such as localStorage) on this website, in line with the Hungarian act on electronic communications and the ePrivacy Directive.

3.1 — What Cookies Are

Cookies are small text files placed on your device by a website. Similar technologies, like localStorage, keep data in your browser without sending it over the network on every request. Some are strictly necessary; others measure how the site is used and are set only with your consent.

3.2 — Cookies & Storage We Use

Consent record (essential): the key cookie_accepted in your browser's localStorage remembers your cookie choice so this banner does not reappear on every visit. It is strictly necessary, lasts until you clear your browser data, and requires no consent. Session state (essential): transient server or CDN cookies needed to deliver pages securely. Analytics (optional): if you accept non-essential cookies, we use privacy-friendly, aggregated analytics to learn which service cards and pages are useful. These are set only after you press "Accept & Pin".

3.3 — Third-Party Services

Our contact page embeds a Google Map (maps.google.com), and Google may set cookies when that iframe loads — you can avoid this by not opening the contact page map, or by adjusting your Google settings. Payment links open Stripe's checkout (stripe.com), where Stripe sets its own essential and fraud-prevention cookies under its privacy policy. Google Fonts and the Tailwind CDN are served over HTTPS without setting cookies of their own under normal browser behaviour.

3.4 — Managing & Withdrawing Consent

You can reject optional cookies by choosing "Essential Only" on the banner, or clear your choice at any time by deleting site data for this domain in your browser settings — the banner will then appear again on your next visit. All major browsers also let you block or delete cookies entirely; blocking essential items may affect basic site functions such as remembering this very choice.

3.5 — Contact

Questions about cookies or this policy? Write to [email protected] or send postal mail to CrystalQueryNest, Kárász utca 11, 6720, Szeged, Hungary.

Refund & Cancellation Policy

Tile 04 / Money Back

We keep this simple: you pay for work delivered, and you can walk away from work that has not started. This Refund & Cancellation Policy applies to all services purchased from CrystalQueryNest, including one-off engagements paid through our Stripe payment link.

4.1 — Cancellation Before Kickoff

Cancel any fixed-scope project before the kickoff date and you receive a full refund of prepaid fees. If you cancel after kickoff but before substantial work has begun, we refund the prepaid amount minus the value of work actually completed, calculated at the hourly rate stated in the SOW, and return any unused balance within 10 business days.

4.2 — EU Cooling-Off Right

If you are a consumer located in the European Union, you have a 14-day right of withdrawal from distance contracts. Because project work can begin immediately on your explicit request, you agree that any work performed during those 14 days may be deducted from your refund; the withdrawal right otherwise applies in full and can be exercised by emailing [email protected] within the 14-day window.

4.3 — Milestones & Defects

Milestone payments cover milestones already accepted; if we miss an agreed delivery date for reasons within our control and the delay exceeds 14 days, you may cancel the remaining scope and receive a refund of fees for undelivered milestones. Reported defects in delivered work are fixed free of charge during the 30-day warranty in the Terms of Service — if we cannot fix a material defect within a reasonable window, that milestone is refunded in full.

4.4 — Retainers

The Pipeline Ops Retainer renews monthly and can be cancelled any time before the next billing date; the current month remains payable and is not pro-rated. If we cancel the retainer, unused prepaid days of the current month are refunded.

4.5 — Delivered Work

Completed audits, delivered reports, and finished sprints that meet the agreed scope are not refundable once accepted. Payments already settled through Stripe are returned to the original payment method; bank fees, if any, are borne by us unless a chargeback is filed in bad faith.

4.6 — How to Request a Refund

Email [email protected] from the address used on your brief, with your invoice number and a one-line reason. We acknowledge requests within 1 business day, decide within 5 business days, and issue approved refunds within 10 business days of approval. Prefer to talk it through first? Call +36 30 678 9012 during desk hours (Mon–Fri, 09:00–18:00 CET).
