ICSL · icsl.eu
For consumer transactions · Version dated 15 September 2026 · The German version is legally binding.
1.1 These GTC apply to consumer transactions within the meaning of Section 1 of the Austrian Consumer Protection Act (KSchG) exclusively for secure communications solutions as a service (aaS) and additional support commissioned in connection with them. ICSL does not offer other deliveries or services to consumers.
1.2 The contracting party is the company named in the offer: ICSL GmbH, company register no. FN 412283z, or ICSL Consulting for Information-Technology and Telecommunications GmbH, company register no. FN 201591h, each at Khunngasse 14, 1030 Vienna, Austria, hereinafter “ICSL”. Contact: office@icsl.at, +43 1 33286 80300.
1.3 Individual agreements take precedence over these GTC.
2.1 Service descriptions, price information and offers by ICSL are non-binding. By placing an order, the customer makes an offer. ICSL is not obliged to accept orders and may decline them without giving reasons. The contract is concluded only upon order confirmation or activation of access by ICSL. An automatic acknowledgement of receipt or payment confirmation does not constitute an order confirmation. Scope of services, number of accounts, prices and term follow from the confirmed offer.
2.2 aaS comprises the agreed use of the secure communications solution operated by ICSL within a closed user group, including the client software required for this. Communication with participants of another closed user group is covered only if agreed and set up by ICSL. Public telephony is not included. The customer receives a usage entitlement for the term of the contract, not an independent licence to operate the server solution.
2.3 The technical requirements follow from the offer. End devices and internet access are provided by the customer. The scope and remuneration of additional support services are agreed in the offer. Remedying warranty defects does not require a paid support order.
2.4 ICSL may engage suitable subcontractors and remains responsible for the performance of the contract.
3.1 Unless another currency is agreed, prices are in euros including applicable VAT. Additional costs are stated before conclusion of the contract and charged only if expressly agreed.
3.2 Consumers can pay fees exclusively by credit card via the payment portal provided by ICSL. A credit card reservation or charge before order confirmation does not constitute acceptance of the order. If ICSL declines the order, any charge already made will be refunded. aaS fees are paid in advance for the agreed billing period; additional support services in accordance with the offer. Statutory rights of retention remain unaffected.
3.3 Flat fees for aaS usage entitlements provided in accordance with the contract are payable irrespective of their actual use. Rights arising from defective performance and statutory rights of withdrawal remain unaffected.
3.4 Price changes and index adjustments require a separate valid agreement with the customer.
3.5 In the event of culpable default in payment, ICSL may suspend the affected service after an unsuccessful reminder with a grace period of at least 14 days and prior notice of the suspension. A justified refusal to pay does not warrant suspension.
3.6 Set-off is permitted in the event of ICSL’s insolvency as well as with counterclaims that are acknowledged, established by a court or legally connected with the payment obligation.
4.1 The statutory warranty and update obligations apply.
4.2 Liability for property damage and financial loss caused by slight negligence is excluded, except in the event of a breach of essential contractual obligations. Personal injury, intent, gross negligence and claims under the Austrian Product Liability Act are exempt from this limitation. This provision also applies in favour of the employees and vicarious agents of ICSL.
5.1 The initial term of the contract follows from the offer. The aaS contract is extended by twelve months at a time unless terminated no later than 90 days before the end of the respective term. Notice of termination may be given by e-mail at any time with effect from the end of the respective term.
5.2 ICSL separately reminds the customer by e-mail 120 days before the end of the term of the upcoming extension and states the last day for giving notice. At least 30 days must lie between receipt of the reminder and that day; otherwise, the automatic extension does not take effect. Notices of termination already given remain effective.
5.3 The right to early termination for good cause remains unaffected.
5.4 In the event of a specific security threat or improper use, ICSL may temporarily restrict the affected services to the extent and for as long as necessary to avert it. Rights arising from defective performance for which ICSL is responsible remain unaffected.
6.1 Information on statutory rights of withdrawal for distance and off-premises contracts is provided in the separate withdrawal notice including the model withdrawal form.
6.2 Austrian law applies, excluding the UN Convention on Contracts for the International Sale of Goods. The mandatory consumer protection provisions of the state in which the customer has their habitual residence remain applicable to the extent they would apply in the absence of this choice of law. The statutory places of jurisdiction apply.
For consumers in distance and off-premises contracts for aaS and additional support · Version dated 15 September 2026 · The German version is legally binding.
You have the right to withdraw from this contract within 14 days without giving any reason. The withdrawal period is 14 days from the day the contract is concluded.
To exercise your right of withdrawal, you must inform your contracting party as named in the offer – ICSL GmbH or ICSL Consulting for Information-Technology and Telecommunications GmbH, each at Khunngasse 14, 1030 Vienna, Austria, e-mail: office@icsl.at, telephone: +43 1 33286 80300 – of your decision by means of a clear statement, for example by letter or e-mail. You may use the model withdrawal form below, but this is not mandatory.
To meet the withdrawal deadline, it is sufficient that you send your notice of the exercise of the right of withdrawal before the withdrawal period has expired.
If you withdraw from this contract, we will refund all payments received from you without undue delay and no later than 14 days after receipt of your notice of withdrawal. We will use the same means of payment that you used for the original transaction, unless you have expressly agreed otherwise. You will not be charged any fees for this refund.
If you expressly requested that the services begin during the withdrawal period, you must pay us, upon withdrawal, a reasonable amount for the services provided up to the time you notified us of your withdrawal, in proportion to the full scope of the contract. This applies only if the statutory requirements, in particular the required information and your express request, are met.
For a paid service, the right of withdrawal ceases only once the service has been fully performed, provided that we began performance with your prior express consent and you acknowledged beforehand that you would lose your right of withdrawal upon full performance of the contract. The mere activation of an ongoing aaS account does not constitute full performance of the contract.
If you wish to withdraw from the contract, please complete this form and return it to us.
