Terms of use

Last updated: 31 October 2026

These terms govern the use of the e-Statistika website, user accounts and the knowledge tests subscription. Please read them carefully. By creating an account you confirm that you have read and accept them; if you do not agree with them, please do not use the website's services.

Service provider

The service is provided by MIODRAG ŠLJUKIĆ PREDUZETNIK AGENCIJA ZA SOFTVERSKI INŽENJERING E-STATISTIKA SOFT SOMBOR, Valjevska 8a, 25000 Sombor, Serbia, registration number 64883283, tax ID 110508813 (hereinafter: e-Statistika). You can contact us through the Contact page.

Website content

Articles, the glossary and other public content are available to everyone free of charge, except to persons and IP addresses banned for abuse. The authors are not liable for the consequences of decisions made on the basis of the published content: understanding it correctly requires some knowledge of statistics, so before an important decision you should consult a qualified person and other sources.

Copyright

Copyright in all content of the website, including articles, the glossary, knowledge test questions and solutions and graphic elements, belongs to e-Statistika. You may read, download, print and quote the content solely for non-commercial purposes, with attribution of the source. Knowledge test questions and solutions may not be copied or published elsewhere.

If you believe that any content on the website infringes your copyright, please let us know through the Contact page.

Account

• An account is personal: it may be used only by the person who created it and may not be shared with others.
• Provide accurate information when registering and keep your password safe; you are responsible for actions taken through your account.
• You can also create an account with a Google or Facebook account; in that case the rules of that network apply as well.
• If you are under 15, you may create an account only with the consent of a parent or guardian.
• We may suspend or close an account that is used contrary to these terms (account sharing, automated downloading of content, disrupting the website).

Knowledge tests and subscription

• The knowledge tests are available with a subscription. Plans, their duration and prices are listed on the Subscription page.
• A subscription becomes valid when the payment is confirmed and lasts for the number of days stated for the chosen plan.
• If you buy a new subscription while the current one is still valid, the new one starts when the current one expires, so you do not lose a single day.
• A subscription does not renew automatically and you are not charged again without a new purchase.
• A subscription is tied to the account and cannot be transferred to another account.

Prices and payment

• Prices are shown in Serbian dinars for customers from Serbia and in euros for customers from other countries and are the final amount you pay.
• Payment methods are shown on the payment page. Card and IPS payments are made on the bank's secure page; customers outside Serbia pay through Lemon Squeezy, which acts as the seller in that purchase, so its terms apply as well.
• After payment you receive an activation confirmation and a fiscal receipt at your account's email address.
• Bank transfers are confirmed on working days; the subscription is activated once the payment is confirmed.

Right of withdrawal

The subscription is digital content that becomes available immediately after payment. Before paying, you expressly agree that access begins immediately after payment and acknowledge that you thereby lose the right to withdraw from a distance contract, in accordance with the Consumer Protection Law of the Republic of Serbia.

Complaints and refunds

You can submit a complaint through the Contact page. We confirm receipt immediately, reply within 8 days at the latest and resolve the complaint within 15 days of receipt at the latest.

We refund the payment if you paid for the same subscription twice or if the subscription was not activated after the payment was confirmed, using the same method of payment, within 15 days of accepting the complaint at the latest.

Links to other websites

The website contains links to other websites and advertisements. We do not control the content of those websites and are not responsible for it.

Technical limitations

We do our best to keep the website running without interruption, but we cannot guarantee it, especially where operation depends on the hosting provider, the bank or other services. Some parts of the website require a recent version of a web browser. If, due to a fault on our side, the website is continuously unavailable for more than 24 hours, we will extend all active subscriptions by the number of started days of the outage. Shorter outages are not added together.

Dispute resolution

These terms are governed by the law of the Republic of Serbia. We will try to resolve any dispute amicably. As a consumer, you may also initiate out-of-court resolution of a consumer dispute before a body on the list kept by the ministry responsible for trade of the Republic of Serbia; the procedure is free of charge for the consumer, and e-Statistika is obliged to take part in it. If the dispute is not resolved, the court in Sombor has jurisdiction, unless consumer law provides for another court.

Changes to these terms

The date of the last update is shown at the top of this page. We notify registered users of significant changes by email before they take effect. Changes do not affect a subscription paid for before they take effect.
