Terms of service.

How we work together on websites, automation, custom systems and other services.

1. Introduction

These terms govern the cooperation between me, Thanh Tam Vu, business ID 08982350, registered at Petržílkova 2267/12, 158 00 Praha 5, Czech Republic (“I” or “the supplier”), and you as the client (“you” or “the client”) for the services offered on tommyvu.cz: websites and apps, automation, custom systems, analysis and project management, IT consulting, graphic design and 3D visualisation.

Different arrangements agreed in an offer or contract take precedence over these terms.

2. The contract

An enquiry sent through the website or by email is not a binding order. Based on your enquiry, I prepare an offer with the scope, price and expected timeline. The contract is concluded when you confirm the offer, usually by email, or sign a separate contract.

3. Price and payment

The price follows the confirmed offer. It may be a fixed amount, an hourly rate or a combination. For larger projects I may ask for an advance payment, stated in the offer. Work beyond the confirmed scope is done only with your approval and charged as agreed.

Payment is made against an invoice with the due date stated on it. If payment is late, I may pause work until the amount is settled.

4. Cooperation, timing and delivery

To finish on time, I need the materials, access and feedback listed in the offer or requested during the work. If they arrive late, the deadline moves accordingly.

I deliver the result for you to try. Please send any comments within 14 days of delivery; small adjustments within the agreed scope are included. If no comments arrive within that period, or you start using the result normally, the work is considered accepted.

5. Copyright and licence

After full payment, I grant you a non-exclusive licence, unlimited in time and territory, to use the delivered work for the purpose agreed in the offer. An exclusive licence or handover of source files is agreed explicitly. General methods, tools and code I also use in other projects remain mine.

Unless agreed otherwise, I may show the work or an example of it in my portfolio. I do not include confidential data in such examples.

You are responsible for the materials you provide (texts, photos, logos, data), including the right to use them.

6. Third-party services

Solutions may rely on third-party services such as hosting, domains, email, payment gateways, APIs or AI tools. You pay their fees unless the offer states otherwise, and their use is governed by the provider’s terms. I am not liable for their outages or changes, but I will help resolve them.

7. Defects and liability

Please report defects without undue delay by email, with a description and steps to reproduce them. I fix defects I caused within a reasonable time. A defect caused by third-party intervention, a change in a third-party service or use contrary to the agreed purpose is not covered.

Outputs of automations and AI tools may contain errors. I therefore build in review and correction options and recommend checking important outputs. Towards businesses, my liability for damage is limited to the price of the relevant project where the law allows. Consumer rights are not affected by this clause.

8. Consumers

If you are a consumer and we conclude the contract at a distance, for example by email, you may withdraw within 14 days of concluding it without giving a reason. Just write to thanhtamvu1297@outlook.com. If you expressly ask me to start before this period ends and then withdraw, you pay a proportionate part of the price for the work already done. Once the service has been fully provided with your prior express consent, the right to withdraw ends.

Consumers have statutory rights for defective performance under the Czech Civil Code. Out-of-court dispute resolution is provided by the Czech Trade Inspection Authority, adr.coi.cz.

9. Final provisions

Personal data protection is described in the privacy notice. Matters not covered by these terms are governed by Czech law, in particular the Civil Code. I may reasonably amend these terms; contracts already concluded follow the version in force when they were concluded. These terms are also available in Czech and Vietnamese; in case of any discrepancy, the Czech version prevails.
