Terms of Use

These Terms of Use (the Terms) govern the use of the "Saobraćaj" app — a trainer for the theory part of the driving licence exam in the Republic of Serbia, available as a mobile app (Android, iOS) and a web app at https://saobracaj.gleb.at (the App or the Service).

By using the App you accept these Terms. If you do not agree with them, do not use the App.

The Serbian version is the legally binding one. This English translation is provided for convenience; a Russian translation is also available.

1. Service provider

Gleb Klimov, independent developer and publisher of the App
Address: [address and registration details of the provider (registration number, tax ID/PIB) — to be completed by the operator before publication]
E-mail: info@gleb.at
Telegram: @GlebKl

(hereinafter we, the Provider).

The processing of your personal data is described in the Privacy Policy, which forms an integral part of these Terms.

2. What the App is

The App is for self-study for the theory exam for drivers: it contains the exam question bank, an exam simulation, statistics of your progress, the text of the Road Traffic Safety Act (Zakon o bezbednosti saobraćaja na putevima), summaries, explanations, question analytics, question lists, groups, public comments and an AI assistant.

The App is not an official means of taking the exam and is not affiliated with the Ministry of Interior, the Road Traffic Safety Agency, driving schools or any other public body. The content (summaries, explanations, analytics, AI-assistant answers) is a study aid and does not constitute legal advice; the applicable regulations and the official exam material prevail. We do not guarantee that you will pass the exam.

The App is intended for persons aged 15 and over.

3. Account

• Most content is available without an account. An account is needed for progress sync, lists, groups, comments, support, the AI assistant and the subscription.
• You can register with an e-mail address and password or with a Google/Apple account. You undertake to provide a valid e-mail address and to keep your credentials secret. You are responsible for actions performed through your account.
• One user may have one account. The account is personal and non-transferable.
• You can delete the account at any time (Settings → Profile → Delete account, or by request to info@gleb.at); instructions: https://docs.saobracaj.gleb.at/delete_account.html. The consequences of deletion are described in the Privacy Policy.

4. Rules of conduct

When using the App, and in particular public comments, groups and the support chat, it is prohibited to:

• post content that is unlawful, abusive, threatening, discriminatory, pornographic or that infringes the rights of others (including privacy and copyright);
• post personal data of other people without their consent;
• send unsolicited messages (spam), advertising, scams;
• interfere with the App: attempt unauthorised access, circumvent access or subscription restrictions, scrape content automatically, overload the server;
• use the AI assistant for purposes unrelated to studying traffic rules, or to generate prohibited content;
• impersonate another person or the Provider.

We reserve the right to remove content that violates these rules without prior notice and to restrict or terminate the account, and in case of serious violations to terminate the contract with immediate effect. Limits on use of the AI assistant (daily quotas) are part of how the Service operates.

5. Content and intellectual property

• The exam questions and the law text come from publicly available sources and remain under the terms of their publishers. Our summaries, explanations, illustrations, analytics, design and the App's source code are protected by the Provider's copyright.
• We grant you a non-exclusive, non-transferable licence to use the App and its content for personal, non-commercial exam preparation. Reproduction, distribution, public communication or commercial use of the content without our written consent is not permitted.
• You retain your rights to content you post yourself (comments, group messages, lists) and grant us a non-exclusive licence to store it, show it to other users within the feature you used and process it to provide the Service. You are responsible for that content.
• AI-assistant answers are generated by artificial intelligence and may be inaccurate or incomplete. Check them against official sources.

6. Subscription and payment

6.1. Free and paid content

Three question categories ("Basics of traffic safety", "Driver" and "Road") are fully open free of charge, including explanations, summaries, analytics and the Russian materials. Every question, the exam simulation, statistics, search, lists and discussions are free in every category. The paid Premium subscription unlocks explanations, summaries, analytics, the Russian materials and the AI assistant in the remaining categories; outside the free categories and without a subscription you see only the beginning of an explanation and, for a summary, its introduction and section titles. The exact scope of the subscription and the prices are shown on the "Tariffs" page before purchase.

6.2. Purchase and prices

• The subscription is bought in the mobile app through the App Store or Google Play by a signed-in user. The web version shows the state of the subscription and the prices for reference, and a purchased subscription works there too.
• Payment with a Russian bank card (in roubles) is available only in the web version, through the payment intermediary lava.top (section 6.8). Rouble prices are fixed and shown on the "Tariffs" page before purchase; the amount charged by lava.top is the final amount payable.
• There is one subscription — Premium — sold as access for 1, 3 or 12 months. The price in your currency, taxes included, is shown by the store at the moment of purchase; that is the final amount payable.
• Access for 3 and 12 months is paid once and ends when the period expires, with no automatic renewal or charging. We notify you before the end by e-mail (14 and 3 days before; reminders can be switched off).
• Monthly access is a subscription that renews automatically every month until you cancel it in the subscription settings of the App Store or Google Play at least 24 hours before the end of the current period. The charge for the next period is made within 24 hours before it starts.
• If you already have an active subscription, a purchased period is appended to the end of the current one. Buying 3 or 12 months does not cancel a monthly subscription — you cancel that yourself in the store.

6.3. Conclusion of the contract and start of the period

The subscription contract is concluded when the store confirms the purchase and we activate the subscription on your account; we notify you by e-mail. If access does not open right after the purchase, use "Restore purchases" in the app or contact info@gleb.at quoting the transaction identifier from the store.

6.4. Right of withdrawal and refunds

Payments are taken and refunds are made by the store (Apple or Google) under its own rules; a refund request is filed with the store. As a consumer you have the right to withdraw from the contract without giving a reason within 14 days from the day of purchase (Art. 27 of the Serbian Consumer Protection Act); file the request with the store, or, if the store does not allow it, send it to info@gleb.at with the transaction identifier and we will arrange the refund. The subscription ends at the moment of withdrawal.

6.5. Complaints

If paid content is unavailable or the Service does not work as described, you have the right to file a complaint. Send it to info@gleb.at or through the developer chat in the app, with a description of the problem and the transaction identifier. We respond to a complaint within 8 days of receipt at the latest and resolve it (fix the problem, extend the subscription period or refund a proportionate part) within 15 days of receipt, in accordance with the Consumer Protection Act.

6.6. Extension if you did not pass the exam

If you did not pass the theory exam while your subscription was active, on your request we extend the access by one month free of charge. The request is made through the developer chat in the app (the "I failed the exam" button in the "Subscription" section) no later than 14 days after the subscription ends, stating the exam date; one extension is granted per purchase. This is a gesture of goodwill, not a guarantee of passing and not a ground for a refund.

6.7. Changes to prices and tariffs

We may change prices and the scope of the subscription. Changes do not affect periods already paid for. If a period length is discontinued, running periods continue until they expire; a monthly subscription renews at the price in force at the time of renewal, of which the store notifies you.

6.8. Payment through lava.top (Russian bank card)

• Payment with a Russian bank card in roubles is made in the web version through the payment intermediary lava.top (Lava Top, https://lava.top). The payment takes place on the lava.top page; we neither receive nor store your card details.
• Access for 3 and 12 months is paid once and ends when the period expires, with no automatic renewal or charges.
• Monthly access is a subscription with automatic renewal: lava.top charges the same amount every month on the same day until you cancel the subscription. We notify you of every charge by e-mail.
• You cancel the subscription in the App at any time ("Subscription" section → "Manage subscription" → "Cancel subscription"). The cancellation takes effect immediately: there are no further charges, and access remains until the end of the period already paid for; no proportionate refund is made for the current period, except in the cases of sections 6.4 and 6.5.
• While a lava.top subscription is running — including one that has been cancelled but has not yet expired — a new subscription or pass cannot be bought; a new purchase becomes possible once the paid period ends.
• Sections 6.3–6.6 apply to lava.top payments, with lava.top in the role of the store: send a refund request or a complaint to us at info@gleb.at (or through the developer chat) with the payment identifier, and the refund is made through lava.top in accordance with its rules (https://lava.top) and the Consumer Protection Act.

7. Availability of the Service and liability

• We strive to keep the Service continuously available but do not guarantee uninterrupted, error-free operation. Interruptions may occur due to maintenance, failures on our side or at our suppliers, or force majeure. We will announce planned longer interruptions when possible.
• The App is provided "as is" to the extent permitted by law. We are not liable for damage arising from misinterpretation of the content, reliance on AI-assistant answers, failing the exam, loss of local data on the device (not synced to an account), nor for indirect damage or lost profit.
• Our total liability to you under the contract is limited to the amount you paid for the Service in the last 12 months, except where the law does not allow liability to be limited (e.g. intent, gross negligence, consumer rights that cannot be limited).

8. Changes to the Terms and the Service

• We develop the App continuously: features may be added, changed or discontinued. Material changes that reduce the scope of a paid subscription do not apply to the current paid period.
• We may change these Terms. The current version is always published at https://docs.saobracaj.gleb.at/terms_of_use.html, and the complete change history — with the date and content of every change — is publicly available in the repository history: https://github.com/Saobracaj/public_documents/commits/main/terms_of_use.md. We will notify you of material changes in the App or by e-mail at least 15 days in advance; continued use after the changes take effect constitutes acceptance. If you disagree, you may stop using the App and delete your account; for a running paid period you retain the right to a proportionate refund if the change materially worsens your position.

9. Termination

You may stop using the App and delete your account at any time. We may terminate your account in case of a breach of these Terms (section 4) or if we discontinue the Service — in the latter case we will refund a proportionate part of the payment for the unused paid period.

10. Governing law and disputes

• These Terms are governed by the law of the Republic of Serbia; consumers retain the protection afforded to them by the mandatory rules of their state of residence.
• We aim to resolve disputes amicably — contact info@gleb.at. A consumer is entitled to out-of-court resolution of a consumer dispute before a body entered in the List of bodies for out-of-court resolution of consumer disputes kept by the ministry responsible for consumer protection (https://mtt.gov.rs); the Provider takes part in such proceedings as required by law. Court disputes are heard by the competent court in the Republic of Serbia and, for consumers, also by the court of their residence in accordance with the law.
