§ 5. Conclusion of Agreement and Account

The use of the Service requires the registration of an Account. Registration is free of charge.
To conclude the Agreement, the Customer should:
1. visit the Service's registration page;
2. complete the registration form: email address, password, optionally company name and Tax ID (NIP), if registering as an Entrepreneur or Entrepreneur with Consumer Rights;
3. mandatorily check the checkbox confirming familiarity with the Terms and Privacy Policy and acceptance of their provisions;
4. optionally check the checkbox concerning consent to receive the newsletter (consent is not a condition of registration);
5. click the "Register" button;
6. follow the activation link sent by the Service Provider to the indicated email address.
Upon clicking the activation link, a free Agreement on the supply of the Service within the Free Plan is concluded, including the issuance of a default API Key.
The Customer may at any time choose a paid Plan, in accordance with the procedure set out in § 8.
A Customer registered as an Entrepreneur who considers that the Agreement does not have a professional character for them within the meaning of the Consumer Rights Act may, no later than at the time of conclusion of the Agreement, submit to the Service Provider a declaration of the non-professional character of the Agreement. The declaration is submitted by checking the appropriate option in the registration form or by sending the declaration to the email address indicated in § 1 section 5. After submitting the declaration, the Customer is treated as an Entrepreneur with Consumer Rights.
The Customer may have only one active Account. Creating multiple Accounts to circumvent Usage Limits constitutes a breach of these Terms.
The Customer declares that they have legal capacity to the extent necessary to conclude the Agreement and that, if they are a natural person, they have reached the age of 16. Concluding the Agreement on behalf of a legal person or organizational unit requires authorization.
The Service Provider declares that it has the legal capacity to enter into a legal relationship and all rights to the Service necessary for its delivery in accordance with these Terms.

§ 6. API Keys

After Account activation, the Customer is granted access to creating API Keys in the management panel.
The Plan's Usage Limits apply at the Account level for all the Customer's active API Keys combined (a single counter per Account, not per Key). The Customer may have up to 20 active API Keys at any time.
The API Key is visible in full form only at the moment of its creation. After leaving the page, its full value is no longer accessible — the Service Provider stores only a secured hash of the Key.
The Customer is obliged to:
1. keep API Keys confidential;
2. not share API Keys with third parties beyond employees and subcontractors involved in the realization of the Customer's own product or service;
3. immediately rotate the API Key if its disclosure is suspected.
The Customer bears full responsibility for the consequences of the use of their API Keys by third parties, if such third parties came into possession of them as a result of disclosure by the Customer or insufficient security on the Customer's side.
The Customer may at any time rotate the API Key (create a new one and invalidate the old one) or revoke the API Key in the management panel.
The Service Provider may revoke the Customer's API Key in the cases set out in § 16 of these Terms.

§ 7. Plans and Usage Limits

The current Plans, along with their Usage Limits, scope of functionalities, and Subscription Fees, are described in the Pricing.
The Free Plan is provided free of charge. A Customer registered in the Free Plan may use the Service within the Usage Limit of the Free Plan.
The choice of a paid Plan (Indie, Pro, Enterprise) results in the conclusion of a paid Agreement within that Plan, in accordance with the procedure set out in § 8.
After exceeding the Plan's Usage Limit, the Service Provider responds to the Customer's requests with HTTP error code 429 (Too Many Requests) along with information about the reset time, until the end of the Usage Limit billing period.
The Customer may optionally enable the Overage mechanism. After enabling Overage, exceeding the Usage Limit does not result in a 429 error response, and additional requests are billed in accordance with the Pricing. The Customer may at any time disable Overage in the management panel.
The Customer may at any time set a Spend Cap — a total monthly limit of expenditure on the Service. The default Spend Cap is 50 USD. After reaching the Spend Cap, the Service Provider responds to requests with HTTP error code 429 until the end of the Billing Period or until the Customer raises the Spend Cap. The Customer receives an email notification upon reaching 70%, 90%, and 100% of the Spend Cap.

§ 8. Fees and Settlements

Prices in the Pricing are expressed in US dollars (USD) and are net amounts. The Payment Operator may add VAT (or other applicable sales tax) to the Subscription Fee based on the Customer's location and the applicable law.
To conclude a paid Agreement, the Customer should select the Plan in the management panel, choose the Billing Period (monthly or annual), complete the invoice data, and make the payment via the payment operator Stripe or its subsidiary, including Link, LLC (hereinafter jointly: "Payment Operator"). The Payment Operator acts as a settlement intermediary (merchant of record) — it calculates and collects consumption taxes (VAT/GST/sales tax) according to the Customer's location and the applicable law, and issues electronic invoices / payment receipts.
Upon the booking of the Subscription Fee, the Customer is granted access to the chosen Plan's functionalities, including its higher Usage Limits. The Payment Operator sends the Customer an electronic invoice to the indicated email address and makes it available in the billing panel (Stripe Billing Portal). The invoice contains the seller's information (Service Provider, business name "QuizBase"), the details of the entity issuing the invoice (Payment Operator), a description of the purchased Plan, and optionally the Customer's Tax ID (e.g. VAT ID/NIP) if the Customer added one in the billing panel.
The Subscription Fee is collected automatically and cyclically in advance, in the rhythm of the chosen Billing Period (monthly or annual), until the Agreement is terminated in accordance with these Terms.
Failure to pay the Subscription Fee by its due date results in the Account being downgraded to the Free Plan, with the corresponding reduction of Usage Limits, until the arrears are settled. In the event of arrears exceeding 14 days, the Service Provider may terminate the Agreement in accordance with § 16.
The Customer may manage the Plan, billing data (including Tax ID / VAT number), invoices, and termination of the Agreement through the Payment Operator's billing panel (Stripe Billing Portal), accessible from the Account.
A change of Pricing does not affect the amount of Subscription Fees set in Agreements concluded before the change of Pricing, until the end of the current Billing Period and its renewals on the existing terms. In the event of renewal of the Agreement for a new Billing Period, the Pricing in force at the time of renewal applies, of which the Customer is informed in advance.

§ 8a. VAT for B2B Customers from the European Union

For B2B Customers from the European Union with a valid VAT identification number (VAT ID / Tax ID), supplied in the Payment Operator's billing panel, the reverse charge mechanism applies in accordance with Article 196 of Council Directive 2006/112/EC. The Payment Operator issues an invoice with a 0% VAT rate, and the Customer accounts for the tax independently in their EU VAT return in their own country.
For B2C Customers (individuals) and B2B Customers without a supplied VAT ID, the Payment Operator calculates and collects VAT at the rate applicable in the Customer's country.
To benefit from the reverse charge mechanism, the Customer should after their first payment go to the Payment Operator's billing panel and add their VAT ID. The VAT ID will appear on all subsequent invoices. A change or removal of the VAT ID does not affect invoices already issued.

§ 9. Content and Licenses

The Content made available through the Service (Questions) comes from various sources and is available under various Content Licenses. Each Question contains, in the API response, a license field with the identifier of the Content License according to the SPDX standard. The current list of sources and Content Licenses is available at https://quizbase.runriva.com/data.
The Customer is obliged to comply with the terms of the Content License of each Question, in particular:
1. for Creative Commons attribution licenses (e.g. CC-BY-4.0, CC-BY-SA-4.0) — to indicate the author or source of the original in the manner required by the license, regardless of the chosen Plan;
2. for Creative Commons share-alike licenses (e.g. CC-BY-SA-4.0, CC-BY-SA-3.0) — to make derivative works available under the same license;
3. for the MIT license or the Service Provider's own license (proprietary-quizbase) — in accordance with their terms set out at the address indicated in section 1.
Holding a paid Plan (Indie, Pro, Enterprise) releases the Customer from the obligation to attribute the Service Provider ("Powered by QuizBase") in the end product. It does not release the Customer from the obligation to comply with Content Licenses of original authors — the Service Provider is not entitled to grant such a release, because the obligation of attribution arises directly from the original author's license, not from the Agreement with the Service Provider.
The Customer bears full responsibility for compliance of Content use with the Content Licenses and for the legal consequences of any infringement of the rights of original authors or third parties.
The Data Dump is made available free of charge at https://quizbase.runriva.com/data in fulfillment of the requirements of the Content Licenses of sources for which such a requirement applies. The Data Dump does not contain enrichments or metadata to which the Service Provider holds exclusive rights.

§ 10. Acceptable Use Policy (AUP)

The Customer undertakes to use the Service in accordance with these Terms, Content Licenses, the law, good practice, and the purpose of the Service.
The Customer may not:
1. introduce into the Service content of an unlawful nature, including content infringing the rights of third parties, copyright, personal rights, the right to image, or criminal law;
2. use the Service for purposes contrary to the law, including for fraud, extortion, propagating hatred, discrimination, disinformation requiring special protection, or other activities prohibited by law;

5. create products competitive with the Service based on retrieved data, the operation of the Service, or its documentation;
6. scrape the dashboard, documentation, or other interfaces of the Service Provider in an automated manner, contrary to the documented API;
7. use the Content to train artificial intelligence models without the express, prior, written consent of the Service Provider;
8. carry out attacks on the Service or its infrastructure providers, including DoS, DDoS, production fuzzing, brute-force attacks, or attempts to obtain unauthorized access;
9. use the Service to distribute malicious software, spam, phishing, or other harmful activities;
10. use the Service in a manner that may mislead end users as to the origin of Content, its author, or its Content License.
The Customer bears full responsibility for the compliance of their use of the Service with these Terms and the law.
In the event of suspected breach of the AUP, the Service Provider may temporarily suspend the Customer's Account in order to clarify the matter, informing the Customer electronically.

§ 11. Use of Artificial Intelligence in Content

The Service Provider informs, and the Customer acknowledges, that part of the Content made available through the Service has been generated or translated with the involvement of language models (Large Language Models). At the time of entry into force of these Terms, the primary AI tool used for this purpose is Google Gemini.
Results generated or translated with the involvement of AI may contain factual errors, linguistic inaccuracies, outdated data, or other irregularities. The Service Provider does not guarantee full factual correctness of the Content.
The Customer undertakes to verify, at their own discretion, the suitability and correctness of specific Content before using it in the end product, especially in educational, professional, or recruitment contexts.
The Customer may report factual errors in the Content via the mechanism described at https://quizbase.runriva.com/legal/report. Reports are processed within the time and procedure of complaints provided for the relevant type of Customer (§ 12).
The Service Provider does not use data entered by the Customer into the Service (Account content, billing data, communication with the Service Provider) to train artificial intelligence models.
Use of the Service does not constitute making an artificial intelligence model or AI-as-a-Service available to the Customer. The Customer does not invoke AI models directly through the API.

§ 12. Complaints

The Customer has the right to submit a complaint regarding the Service, in particular in the event of disclosed Non-Conformity (Consumer or Entrepreneur with Consumer Rights) or other irregularity in the operation of the Service.

A Consumer and an Entrepreneur with Consumer Rights have the right to withdraw from the Agreement without giving any reason within 14 (fourteen) days of its conclusion, on the terms set out in Article 27 et seq. of the Consumer Rights Act.
The Service Provider extends the right to withdraw from the Agreement without giving any reason within 14 days also to Entrepreneurs who are not Entrepreneurs with Consumer Rights. The provisions of this paragraph apply mutatis mutandis to Entrepreneurs.
The right of withdrawal referred to in sections 1-2 does not apply to the Customer if the following conditions are met cumulatively, in accordance with Article 38 point 13 of the Consumer Rights Act:

Exercise of the right of withdrawal takes place by submitting to the Service Provider a declaration of withdrawal from the Agreement. The declaration may be submitted in any form, in particular on the form constituting Annex 2 to the Consumer Rights Act, via email to the address indicated in § 1 section 5. To meet the deadline, it is sufficient to send the declaration before the deadline expires.
In the event of effective withdrawal from the Agreement, the Service Provider returns the Subscription Fees received within 14 days of receipt of the declaration, via the same channel by which the Customer made the payment.
Effective withdrawal from the Agreement results in retroactive termination of the Agreement and blocking of the Account and API Keys. The Customer retains access to public Service resources (Data Dump, documentation).

§ 14. Liability and Service Level

The Service Provider undertakes to provide the Service with due diligence.
The Service Provider does not grant a guarantee of a specific level of Service availability (uptime).
