SYLS Service Terms — syls.eu

Effective from 26 July 2026.

1. Scope and provider

  1. These Terms govern the use of syls.eu and the paid SYLS service for launching and technically maintaining an online store under a recurring subscription.
  2. The Service is provided by kowal sp. z o.o., ul. Przekopna 6/1, 38-100 Strzyżów, Poland, VAT ID PL8191670708, REGON 383765987, KRS 0000793162, registered by the District Court in Rzeszów, 12th Commercial Division of the National Court Register, share capital PLN 5,000 (“SYLS”, “we” or the “Provider”).
  3. Contact:
    • Service, complaints and illegal-content notices: hello@syls.eu;
    • postal contact: the Provider's registered address above.
  4. The Terms are made available free of charge before the contract is concluded in a format that can be saved and reproduced.

2. Definitions

  1. Customer — a natural person, legal person or organisation entering into the contract with SYLS.
  2. Consumer — a natural person acting for purposes outside their trade, business, craft or profession.
  3. Service — the managed SYLS online-store environment and the features included in the selected Plan.
  4. Store — the Customer's store instance operated through the Service.
  5. Authorised User — a person whom the Customer permits to use the Store administration or account.
  6. Plan — START, GROWTH or PRO as described in the current pricing page.
  7. Billing Period — monthly or annual, as selected during purchase.
  8. Customer Content — data, text, images, files, products, order information and other material submitted to the Store by the Customer, Authorised Users or Store end users.

3. The Service

  1. Depending on the Plan, the Service includes Store provisioning, a seller administration panel, hosting, SSL after correct domain configuration, monitoring, technical backups, platform updates and the e-commerce features listed in the pricing page and documentation.
  2. A Store may initially use a SYLS platform subdomain. Connecting a custom domain requires the Customer to configure DNS as instructed and pass verification.
  3. The applicable Plan is the one shown at checkout. Roadmap items, previews, beta features and general marketing statements are not contractual commitments unless expressly included in the Plan.
  4. SYLS is not the seller of products offered through a Store, a party to contracts between the Customer and Store buyers, the payment provider for Store purchases, or a delivery provider.
  5. Third-party integrations are also governed by their providers' terms. SYLS does not guarantee that a third-party service will remain available, but will reasonably inform Customers of material changes affecting the Service.

4. Technical requirements and accounts

  1. Use requires an internet-connected device, a current browser supporting HTTPS and JavaScript, an active email address and the ability to receive account messages.
  2. The Customer must provide accurate, complete and current information. A person registering for an organisation confirms that they are authorised to bind it.
  3. The Customer must protect credentials, use strong passwords and manage Authorised Users. Suspected compromise must be reported without undue delay.
  4. Customers must not share access with unauthorised persons, bypass safeguards, test vulnerabilities without written permission, disrupt the Service, introduce malicious code or use automated access that unreasonably burdens the systems.

5. Contract formation and launch

  1. Website and pricing information is an invitation to contract. The Customer selects a Plan and Billing Period, provides the required data, accepts the Terms and proceeds to payment.
  2. Immediately before ordering, the Customer is shown the main features, total price and applicable taxes, billing frequency, automatic renewal and cancellation method. The final order button clearly indicates an obligation to pay.
  3. The contract is concluded when Stripe confirms successful payment and SYLS accepts the order. Confirmation and the applicable Terms are sent to the Customer by email on a durable medium.
  4. Provisioning starts after payment confirmation. Any displayed launch time is an estimate unless SYLS expressly agrees a separate service level.
  5. SYLS may reject an order or pause provisioning if information is clearly false, payment is not confirmed, the proposed use is unlawful or there is a reasonable security risk. Fees for a Service not provided will be refunded.

6. Prices, recurring payments and invoices

  1. Prices on syls.eu are displayed in EUR. Consumers are shown gross prices including VAT. Customers purchasing as a business are shown net prices, with VAT added under the applicable tax rules. Before payment, checkout always displays the VAT due and the total amount payable.
  2. Stripe processes subscription payments. SYLS does not store complete card numbers. Stripe may apply its own authentication, security and fraud-prevention measures.
  3. Subscriptions renew automatically for consecutive Billing Periods until cancelled. Stripe charges the stored payment method at the price accepted at purchase or a later price introduced in accordance with section 16.
  4. The Customer must maintain a valid payment method. Following a failed payment, SYLS may retry payment and, after reasonable notice, restrict or suspend the Store unless immediate action is required for security.
  5. Invoices are issued electronically using the billing details supplied by the Customer.
  6. Fees charged by Store payment providers, carriers, registrars or optional integrations are not included unless expressly stated. SYLS does not charge its own commission on sales made through a Store.

7. The Customer as merchant

  1. The Customer is solely responsible for the business operated through the Store, including:
    • legality of products, services and Customer Content;
    • prices, taxes, invoicing and sales records;
    • Store terms, privacy and cookie information, and consent mechanisms;
    • consumer information, complaints, returns and withdrawal rights;
    • fulfilment, Store payment methods and deliveries;
    • rights to names, trade marks, images, descriptions and other content;
    • compliance with the laws of every country to which sales are directed.
  2. The Customer is the controller of personal data of its Store buyers, staff and business contacts. SYLS processes that data on the Customer's behalf under the Data Processing Addendum below.
  3. Templates and compliance features supplied by SYLS are general tools and do not constitute individual legal, tax or accounting advice.

8. Content and intellectual property

  1. The Customer retains its rights in Customer Content and grants SYLS a non-exclusive, royalty-free licence, limited to the term and purpose of the Service, to host, reproduce, technically adapt, back up, transmit and display Customer Content through the Store.
  2. The Customer confirms it has all rights and lawful grounds required to use and instruct SYLS to process Customer Content.
  3. SYLS software, templates, documentation, branding and materials remain the property of SYLS or its licensors. The Customer receives a non-exclusive, non-transferable right to use them during the contract.
  4. Feedback may be used to improve the Service without transferring the Customer's rights in Customer Content.

9. Prohibited use and Digital Services Act notices

  1. The Service must not be used for unlawful activity or content that infringes the law, third-party rights, system security or these Terms. This includes fraud, malware, phishing, unlawful incitement to violence or hatred, child sexual abuse material, intellectual-property infringement and unlawful trade.
  2. A notice of allegedly illegal content may be sent to hello@syls.eu with the subject “DSA content notice”. It should include:
    • the exact URL or other precise location;
    • a reasoned explanation of illegality;
    • the notifier's name and email, except where the law permits omission;
    • a good-faith statement that the information is accurate.
  3. SYLS will acknowledge the notice and decide in a timely, diligent, objective and proportionate manner. It may leave content available, restrict visibility, remove it, restrict a feature or suspend an account.
  4. When restricting Customer Content or an account, SYLS will provide a statement of reasons and information on available redress, unless prohibited by law or an urgent risk makes this inappropriate.
  5. The Customer may challenge the decision by email within six months. This does not limit a right to complain to the competent Digital Services Coordinator or to seek judicial redress.

10. Operations, security and backups

  1. SYLS applies technical and organisational safeguards and performs monitoring, updates and technical backups within the applicable Plan.
  2. The Service may be temporarily unavailable for maintenance, updates, incidents, infrastructure-provider failures or events beyond SYLS's reasonable control. Planned work causing material downtime will be announced where reasonably possible.
  3. Technical backups support disaster recovery and do not replace the Customer's own business exports. Recovery of an individual item or Customer-deleted data is not guaranteed unless expressly included in the Plan.
  4. Customers must implement security recommendations and updates that require their action.

11. Support and complaints

  1. Support requests and complaints may be submitted through the account or to hello@syls.eu. They should identify the account, describe the issue and time, and state the requested remedy.
  2. Consumer complaints will be answered within 14 days where Polish law applies or within any shorter mandatory period under the Consumer's local law. Business support is handled within a reasonable period based on severity and Plan unless a separate SLA applies.
  3. SYLS may request information needed to reproduce an issue. Customers must not send passwords, full payment-card data or unrelated personal data.

12. Consumer digital-service rights

  1. SYLS will supply the digital Service in conformity with the contract, including its description, functionality, continuity, security, support and updates as required by applicable law.
  2. If the Service is not in conformity, a Consumer may require it to be brought into conformity. Where that is impossible, disproportionate, unsuccessful or the lack of conformity is sufficiently serious, the Consumer may be entitled to a price reduction or termination under applicable consumer law.
  3. Nothing in these Terms excludes statutory remedies or guarantees that cannot lawfully be excluded.

13. Consumer right of withdrawal

  1. An EU Consumer entering a distance contract generally has 14 days from conclusion to withdraw without giving a reason, subject to mandatory national rules.
  2. Notice may be sent to the registered address or hello@syls.eu. Sending it before the deadline is sufficient; SYLS will acknowledge electronic withdrawal.
  3. If the Consumer expressly requests performance to begin during the withdrawal period and then withdraws, the Consumer may have to pay a proportionate amount for the Service supplied up to withdrawal, provided the required information was given.
  4. The right may be lost after full performance of a paid service only where performance began with the Consumer's prior express consent, the Consumer acknowledged the loss of the right, and all statutory conditions were met. Launching a continuing subscription does not by itself mean that the entire contract has been fully performed.
  5. Any required refund will be made without undue delay and no later than 14 days after valid withdrawal, using the original payment method unless otherwise agreed.

Model statement:

I, [name], withdraw from the SYLS Service contract concluded on [date] for [account email / Store identifier]. Date and signature (only for a paper notice).

14. Cancellation, suspension and termination

  1. The Customer may turn off renewal through the Stripe Customer Portal or by contacting SYLS before the next Billing Period.
  2. Subject to mandatory Consumer rights, cancellation takes effect at the end of the paid Billing Period and does not refund a period already started.
  3. SYLS may suspend the Service for overdue payment, security risks, unlawful use or material breach. Where reasonably possible and safe, the Customer will first be asked to cure the breach.
  4. SYLS may terminate immediately for a serious or repeated breach, a binding authority order or a material threat. Otherwise, SYLS will give at least 30 days' notice.
  5. For 30 days after termination, the Customer may request an export of Customer Content in a reasonable, technically available format. Production data is then deleted unless retention is legally required. Backups are removed through rotation within no more than 90 days.
  6. Billing records, evidence of acceptance and logs may be retained where required by law or necessary for legal claims.

15. Liability

  1. SYLS is liable under applicable law for failure to perform the contract. Nothing limits liability or remedies that cannot lawfully be limited for Consumers.
  2. The Customer is responsible for Store operations, Customer Content, relationships with Store buyers and Authorised Users.
  3. For Customers acting in business:
    • SYLS is not liable for indirect loss, lost profit, loss of goodwill or loss of opportunity, except for wilful misconduct;
    • aggregate liability relating to a Store is limited to net fees paid for that Store during the 12 months preceding the event;
    • these limits do not apply to wilful misconduct, confidentiality or data-protection breaches, or where limitation is prohibited by law.

16. Changes to the Service, price and Terms

  1. SYLS may develop the Service without materially reducing the paid Plan. Security and legally required changes may be implemented immediately.
  2. SYLS will give at least 30 days' notice on a durable medium of a new renewal price or a material change to these Terms. The Customer may cancel without an additional fee before the change takes effect.
  3. A change does not affect accrued rights, a period already paid for or claims arising earlier.

17. Governing law and disputes

  1. Polish law governs the contract. This choice does not deprive a Consumer of protection under mandatory provisions of the country of their habitual residence.
  2. A Consumer may use available out-of-court redress, including a competent national ADR body listed by the European Commission. SYLS does not commit to a particular ADR procedure unless required by law or separately agreed.
  3. The former EU Online Dispute Resolution platform was discontinued in 2025 and these Terms do not link to it.
  4. Business disputes are subject to the courts competent for the Provider's registered office, unless mandatory law requires otherwise.
  5. These Terms are provided in English for syls.eu. A translation may be provided for convenience; for Consumers, mandatory language and transparency requirements of the targeted country remain applicable.

Data Processing Addendum

A. Roles, subject matter and duration

  1. For personal data of Store buyers, recipients, staff and other persons entered into the Store, the Customer is controller and SYLS is processor.
  2. Processing lasts for the Service term and covers hosting, recording, organising, retrieval on Customer instruction, transmission, backup, support, security and deletion for the purpose of providing the Service.
  3. Data subjects may include buyers and prospective buyers, shipment recipients, business contacts, employees and Authorised Users.
  4. Data may include identifiers, contact, address, billing and shipping data, account data, order history, communications, device identifiers and logs. Special-category data and criminal-offence data must not be submitted without prior agreement on suitable safeguards.

B. Instructions and processor duties

  1. SYLS processes data only on documented Customer instructions arising from the contract, configuration and lawful use of the administration tools, unless Union or Member State law requires otherwise.
  2. SYLS ensures confidentiality of authorised personnel, appropriate security, and reasonable assistance with data-subject rights, data protection impact assessments, consultations and breach obligations.
  3. SYLS will notify the Customer of a personal data breach concerning entrusted data without undue delay after becoming aware of it and provide available information required for the Customer's compliance.
  4. The Customer is responsible for lawful instructions, transparency information, legal bases, access configuration and responses to data subjects.

C. Security measures

SYLS applies measures appropriate to risk, including access control, encryption in transit, tenant separation, patching, administrative event logs, monitoring, backups, recovery procedures and periodic security testing. Further details may be provided subject to security and confidentiality.

D. Subprocessors and international transfers

  1. The Customer gives general authorisation for subprocessors necessary to provide the Service. SYLS must publish a current list at a stable address before these Terms go live.
  2. The infrastructure uses Hetzner Online GmbH in the EU. Monitoring and backups operate within that infrastructure, and SYLS email is maintained by the Provider at mx.kowal.co. Any additional external provider must be added to the public list before use.
  3. SYLS will give advance notice of a planned change, allowing a reasoned data-protection objection. If no reasonable solution is available, the Customer may terminate the affected Service.
  4. SYLS imposes no less protective data obligations on subprocessors and remains responsible for their performance under Article 28 GDPR.
  5. Processing occurs in the EEA unless the Customer is informed of a lawful transfer mechanism, such as an adequacy decision or Standard Contractual Clauses.

E. Return, deletion and audit

  1. At the end of the Service, SYLS will return or delete entrusted data at the Customer's choice and subject to section 14, unless retention is required by law.
  2. SYLS provides information necessary to demonstrate compliance and permits an audit no more than once per year on reasonable notice, during business hours and without compromising other Customers. Reports, certifications and remote review are used first; an on-site audit requires justification and agreed confidentiality, security and cost arrangements.
