Czech version (binding)

1. Data controller

The controller of personal data is the sole trader operating the SmlouvaHned.cz platform (the “Controller”):

ControllerKarel Zdeněk, sole trader
Company ID (IČO)23660295
Place of businessPlzeňská 189, 345 61 Staňkov, Czech Republic
Contact e-mailinfo@smlouvahned.cz
Websitesmlouvahned.cz

The Controller processes personal data in accordance with Regulation (EU) 2016/679 of the European Parliament and of the Council (GDPR) and Act No. 110/2019 Coll., on personal data processing.

2. What personal data we process and why

Data entered into the contract form

Names, addresses, dates of birth, ID-card numbers and company IDs of the contracting parties, which you enter into the form yourself.

Purpose: Generating a standardised contract document from the data you enter.
Legal basis: Performance of a contract (Art. 6(1)(b) GDPR).
Retention: For the free experiment at most 24 hours from creation; no e-mail is required for that flow. For a paid document 7–30 days from payment depending on the variant purchased, or 90 days with the archiving add-on. The data is then deleted automatically from the temporary storage.
E-mail address

The delivery e-mail is entered by the customer before proceeding to payment.

Purpose: Sending the download link, the order confirmation and secure access to the customer zone.
Legal basis: Performance of a contract and legitimate interest (Art. 6(1)(b) and (f) GDPR).
Retention: 7–30 days from the order depending on the document purchased, or 90 days with the archiving add-on, then deleted automatically.
Contact form

The name, e-mail, subject and content of the message you send from the Contact page.

Purpose: Handling a query, a complaint or a customer request.
Legal basis: Pre-contractual negotiation, performance of a contract or legitimate interest in customer support (Art. 6(1)(b) and (f) GDPR).
Retention: For as long as the request is being handled, at most 12 months from the last communication; longer only where required by law or to protect legal claims.
Newsletter (tips and news)

Only if you explicitly subscribe in the site footer, tick the consent box and then confirm the subscription through the link sent to the address given (double opt-in).

Purpose: Sending practical tips about documents and information about the SmlouvaHned service.
Legal basis: Consent (Art. 6(1)(a) GDPR).
Retention: Until consent is withdrawn or the subscription is cancelled (link in every e-mail).
Moje zakázka (continuing a job)

Only if, after paying for a work contract, you choose “Continue as a job”. The job holds your e-mail from the order, the job name, your role (client/contractor), the deadline, the price and pricing mode from the contract, the phase, tasks, notes, history and the details you add to follow-up documents (for example party names, a description of defects). Neither the content of the contract nor the counterparty’s contact details are copied into the job.

Purpose: Tracking the progress of the job, sending return links and functional deadline reminders (only if you switch them on), and creating follow-up documents.
Legal basis: Performance of a contract (Art. 6(1)(b) GDPR); the reminders are functional notifications about your job, not commercial communications.
Retention: 12 months from the last change to the job; a job marked as closed 6 months from closing (a fixed date that further edits do not extend); an unpaid draft follow-up document 30 days from creation — after that it is no longer displayed and is removed by the automatic daily clean-up no later than the following day. Neither the content of the contract nor the payment identifier is stored in the job; from follow-up documents only what you write into them is kept. You can export the job (JSON) or delete it at any time from your overview; return links (valid 30 days) can be invalidated at any time.
Request for a follow-up service (commercial intent)

Only if you explicitly ask to be contacted by a specific partner: the service category, a short description, urgency, price range, region and the contact details you choose to share. A record of consent is stored with the request (partner, purpose, shared fields, text version, time of granting and of withdrawal).

Purpose: Passing your request to the partner you selected. Without an onboarded partner the request stays stored and is not passed anywhere.
Legal basis: Consent (Art. 6(1)(a) GDPR) granted specifically for that partner; it can be withdrawn at any time.
Retention: 6 months from creation, then automatic erasure. After consent is withdrawn the contact details are removed from the request immediately.
Free tools (checklists, guides)

The state of a checklist is stored only in your browser (localStorage). No content is sent to the server — only an anonymous “tool started / completed” event, and only with your consent to product analytics.

Payment details

Card numbers and bank details are processed exclusively by the Stripe payment gateway (Stripe, Inc., USA). The Controller has no access to them. More about Stripe and the GDPR: stripe.com/privacy.

3. Recipients of personal data

Personal data may be passed to the following processors:

  • Stripe, Inc. — payment processing. A processor under Art. 28 GDPR, PCI DSS Level 1 certified.
  • Upstash (Redis) — temporary storage of form data while the document is generated and downloaded (7–30 days depending on the document purchased, or 90 days with the archiving add-on).
  • Resend — transactional e-mails, delivery of the document link, forwarding of contact-form messages and sending the newsletter to confirmed subscribers.
  • Upstash (Redis) — temporary record of an unconfirmed newsletter subscription for 24 hours and a record of confirmed consent for the duration of the subscription.
  • Upstash (Redis) — job data (Moje zakázka) for 12 months from the last change (a closed job 6 months), hashes of return tokens and the reminder schedule; requests for follow-up services for 6 months.
  • Stripe, Inc. — also payment for a follow-up job document; Stripe receives your e-mail and the document name, not its content.
  • Vercel — hosting of the platform. Data is processed within the EEA or under corresponding safeguards.

A follow-up partner does not automatically receive the content of the contract or your contact details. The offer is selected from minimised categories. Only by a deliberate click does the user move to a specific provider’s website; any transfer of contact details requires separate, specific consent for that partner.

The Controller does not sell personal data to third parties. Marketing e-mails (the newsletter) are sent solely on the basis of voluntary consent, which you can withdraw at any time.

4. Transfers outside the EEA

Stripe, Inc. and Resend are based in the USA. Transfers are safeguarded by standard contractual clauses (SCC) approved by the European Commission together with supplementary technical measures. Upstash and Vercel allow an EU region to be selected (which applies to our deployment).

5. Your rights

  • Right of access — you may ask what data we process about you.
  • Right to rectification — you may ask us to correct inaccurate data.
  • Right to erasure — you may ask for your data to be deleted.
  • Right to restriction of processing — you may ask us to restrict processing.
  • Right to data portability — you may receive your data in a machine-readable format.
  • Right to object — you may object to processing based on legitimate interest.

Exercise your rights at info@smlouvahned.cz. We will respond to your request within 30 days.

6. Cookies and analytics

SmlouvaHned uses no third-party marketing or profiling cookies. Technically necessary session cookies may be used for the basic functioning of the application. No behavioural advertising platform (Facebook Pixel, Google Ads remarketing and the like) is deployed on the website.

For anonymised traffic statistics we use Vercel Web Analytics (aggregated page views, without identifying a specific person). Our own product events (for example entering a form or clicking through to checkout) are sent only after your optional consent and without any link to a payment card; completed payments are recorded by the server only after Stripe confirms them.

Regardless of that choice, the server may record the necessary aggregated security and operational signals about rejected or invalid requests, so that checkout can be protected and an outage detected. These signals contain neither form content nor contact details and do not count as revenue or completion.

Only after that consent do we store, in first-party session storage and for the purpose of evaluating the path to the product, the category of the first source, the public page path and possibly an article slug. We actively delete the record after 30 minutes; an older record is additionally rejected and deleted on every read. The attribution itself contains no user UUID, form content, VIN, name, e-mail, telephone number or address. If you subsequently create a document, however, the server attaches a copy of this minimised attribution to the secure document record, so for that period it may be linkable to the order data: 24 hours for the free flow, 7–30 days for a paid document, or 90 days with the archiving add-on. The raw reporting buffer holds at most 5,000 events and the dashboard works with the last 30 days. We pass neither the attribution nor the order data to any affiliate partner.

Withdrawing consent stops further browser product events and new attributions and immediately deletes the attribution from the current browser tab. It does not retroactively remove server events already received or the attribution attached to a document created earlier; a server-side completion or download of such a previously attributed document may therefore be recorded for as long as it remains available. You can exercise your rights over these records as described in section 5.

Analytics consent can be changed at any time on the Czech version of this page, where the settings panel is available.

7. Data security

All communication is encrypted with TLS (HTTPS). Form data is stored in encrypted temporary storage with automatic erasure after 7–30 days depending on the document purchased, or after 90 days with the archiving add-on. Access to the data is limited to technically necessary persons. Payment details never pass through our servers.

8. Right to lodge a complaint

You have the right to lodge a complaint with the supervisory authority — the Office for Personal Data Protection (Úřad pro ochranu osobních údajů, ÚOOÚ), Pplk. Sochora 27, 170 00 Prague 7, Czech Republic, www.uoou.cz.
