Terms of Service

1. Definitions

2. Acceptance of Terms

2.1 Agreement to Terms

By accessing or using any AdPriva Service, you confirm that:

• You have read, understood, and agree to be bound by these Terms
• You have the legal capacity to enter into a binding agreement
• If acting on behalf of a company or organisation, you have authority to bind that entity

2.2 Supplemental Terms

These Terms apply to all users. Additional terms may apply depending on your role:

• Publishers are also subject to the Publisher Agreement
• API users are also subject to the API Terms of Use

In the event of a conflict between these Terms and any supplemental agreement, the supplemental agreement prevails with respect to the specific subject matter.

2.3 Electronic Acceptance

Creating an account, integrating the AdPriva Tag, or otherwise using the Services constitutes electronic acceptance of these Terms with full legal effect under Portuguese and EU law.

3. Description of Services

AdPriva operates a privacy-preserving traffic validation and cryptographic proof infrastructure. AdPriva is a neutral referee: it validates traffic, scores a Verdict, and seals the result into a Merkle batch with a batch receipt, as tamper-proof evidence anyone can re-check by its ID. AdPriva does not serve ads, run the auction, or sit in the serving path. The Services include:

3.1 AdPriva Console

A login-gated web platform for publishers and clients to review traffic breakdowns, validity segments, bot-rate by source, and downloadable audit certificates, and to manage integrations and reporting.

3.2 AdPriva Tag (tag.js)

A headless JavaScript tag that publishers integrate on their websites to capture behavioural signals and submit them for validation. The Tag sets no tracking cookies, renders nothing on the page, and requires no changes to existing funnels.

3.3 Public Explorer

A public verification interface at explorer.adpriva.com where anyone can verify a single Proof by its ID and receive back the same Verdict, sealed hash, batch receipt, and timestamp (plus the anchored block for records anchored before the pause) — with no raw traffic, no IPs, and no client data exposed. It is a verification lookup, not a feed.

3.4 Verification Infrastructure

Cryptographic proof generation, Merkle-tree batch construction with batch receipts, and an archive of the evidence from earlier anchoring. Public blockchain anchoring on Horizen is paused since November 4, 2026, and zkVerify is not used for new batches since October 16, 2026.

3.5 API Access

Programmatic access to AdPriva's traffic-validation, proof generation, and reporting capabilities via REST API.

3.6 AI-Assisted Classification — Disclaimer

AdPriva uses AI-based and machine-learning systems, including behavioural models, for traffic classification and fraud detection. AdPriva does not warrant that:

• Classification of traffic is accurate or complete in all cases
• Verdicts will be free from classification errors
• Fraud detection systems will correctly classify all activity at all times

Verdicts and Validity Scores are produced by AdPriva's cryptographic measurement systems; traffic below the confidence threshold is flagged as uncertain rather than guessed. In the event of a demonstrable classification error, AdPriva's sole obligation is to use reasonable efforts to make corrections on a prospective basis. AdPriva is not liable for historical impacts arising from classification errors.

4. Eligibility

4.1 Age Requirement

You must be at least 18 years old (or the age of majority in your jurisdiction, if higher) to register for or use the Services. The Services are intended for publishers and their authorised personnel and are not directed at, and may not be used by, persons under 16.

4.2 Geographic Restrictions

AdPriva makes no representation that the Services are appropriate or available in all jurisdictions. You are responsible for compliance with local laws where you access the Services.

4.3 Prohibited Persons

You may not use the Services if you are:

• Subject to applicable sanctions lists (EU, UN, OFAC, or equivalent)
• Prohibited from receiving services under applicable law
• A competitor using the Services for competitive intelligence without prior written consent

5. Account Registration

5.1 Accuracy of Information

You agree to provide accurate, current, and complete information when registering and to maintain accuracy throughout the term of your account.

5.2 Account Security

You are responsible for: maintaining the confidentiality of your credentials; all activity that occurs under your account; and immediately notifying AdPriva at hello@adpriva.com of any unauthorised access. AdPriva will not be liable for losses resulting from unauthorised use of your account where you have failed to safeguard your credentials.

5.3 One Account Per Entity

Each legal entity may register only one account unless expressly agreed otherwise in writing.

5.4 API Keys

API keys are confidential credentials. You must not share API keys publicly, embed them in client-side code, or commit them to public repositories. You are responsible for all API usage under your keys.

6. Publisher Terms

6.1 Integration Requirements

Publishers integrating the AdPriva Tag agree to:

• Integrate the AdPriva Tag only on websites and applications they own or control
• Comply with all applicable laws including GDPR, ePrivacy Directive, and national implementations
• Obtain all necessary user consents for data processing on their own websites independently of AdPriva
• Not modify, decompile, reverse-engineer, or circumvent the AdPriva Tag
• Integrate the AdPriva Tag in accordance with AdPriva's integration documentation

6.2 Publisher Consent Obligations and Data Protection Liability

Publishers are solely liable for:

• All regulatory fines, penalties, and enforcement actions arising from their own failure to obtain valid user consent
• All third-party claims arising from their website's data collection and processing practices
• Any GDPR or ePrivacy enforcement action directed at their own processing operations
• Costs of defending any regulatory investigation of their own data practices

AdPriva is not jointly liable for publisher-side GDPR or ePrivacy violations. Publishers agree to indemnify and hold AdPriva harmless against any claim, fine, penalty, or regulatory action arising from the publisher's own consent failures or data protection violations.

6.3 Prohibited Publisher Content

Publishers may not use the AdPriva Tag on websites or applications that:

• Contain child sexual abuse material or content sexualising minors
• Promote, facilitate, or glorify violence, terrorism, or hate speech
• Engage in or facilitate illegal activity
• Violate third-party intellectual property rights
• Are directed primarily at children under 16 without explicit notification to AdPriva
• Use deceptive patterns or dark UX to generate artificial traffic or manipulate validation

6.4 Publisher Fees and Plans

Access to the Services is provided on a subscription or usage basis as set out in the Publisher Agreement or Console account configuration. Fees are based on validated traffic volume and the plan selected. AdPriva charges publishers for validation; it does not share revenue with, or make any payments to, publishers or website visitors.

6.5 Publisher Representations

Publishers represent and warrant that: they have full right, title, and authority to integrate the AdPriva Tag on their properties; their properties comply with all applicable laws; their properties do not infringe any third-party intellectual property rights; and they have the right to submit their traffic for validation under applicable law.

7. Website Visitors & Consent

7.1 Validation of Visitor Traffic

When you visit a Publisher's property that integrates the AdPriva Tag, your interaction may be validated to classify the traffic as human, auth_agent, abusive_bot, or uncertain. AdPriva captures behavioural signals for this integrity purpose only. AdPriva does not build cross-site profiles, does not serve you ads, and runs no consumer incentive or payment programme.

7.2 Consent Certificates

Where a Publisher captures your consent through a form, AdPriva may seal a Consent Certificate — a cryptographic record that consent was given — and group it into a Merkle batch with a receipt for independent verification (certificates anchored before the pause keep their anchor reference). The certificate records a hash of the consent statement and related metadata, not the raw personal data, and can be re-verified through the public Explorer.

7.3 Your Rights

Your personal data is processed as described in our Privacy Policy. You may exercise your data-subject rights — including access, rectification, and erasure — as set out there.

8. Intellectual Property

8.1 AdPriva Ownership

AdPriva and its licensors retain all intellectual property rights in and to the Services, including all software, code, algorithms, cryptographic systems, the AdPriva brand and trademarks, all documentation and APIs, and all data and aggregated insights generated by the platform.

8.2 Limited Licence

AdPriva grants you a limited, non-exclusive, non-transferable, revocable licence to access and use the Console for account management, integrate the AdPriva Tag on your authorised publisher properties, and access the public Explorer. This licence does not include any right to sublicense, modify, copy, or create derivative works.

8.3 Your Content

You retain ownership of content you submit to AdPriva. By submitting content, you grant AdPriva a non-exclusive, worldwide, royalty-free licence to use, process, and display that content as necessary to provide the Services.

8.4 Feedback

Any feedback, suggestions, or ideas you provide regarding the Services may be used by AdPriva without restriction or compensation to you.

9. Prohibited Conduct

You agree not to:

• Use the Services for any unlawful purpose or in violation of these Terms
• Attempt to gain unauthorised access to any part of the Services or AdPriva's systems
• Interfere with or disrupt the integrity or performance of the Services
• Attempt to reverse-engineer, decompile, or extract source code from AdPriva's software
• Use automated tools to scrape, crawl, or harvest data from the Services without permission
• Impersonate any person or entity or misrepresent your affiliation
• Use the Services to transmit malware, viruses, or harmful code
• Attempt to circumvent, spoof, or manipulate AdPriva's fraud detection or validation systems
• Re-identify or attempt to identify individuals from AdPriva's anonymised or pseudonymised data
• Use AdPriva data to build competing products without written consent
• Facilitate or encourage any third party to do any of the above

Violation of these prohibitions may result in immediate account suspension, termination, and legal action.

10. Privacy and Data Processing

10.1 Privacy Policy

AdPriva's collection and use of personal data is governed by our Privacy Policy, which is incorporated into these Terms by reference.

10.2 Data Processing Agreement

For publishers who process personal data using AdPriva's Services, a Data Processing Agreement (DPA) is available on request at hello@adpriva.com and may be required under GDPR Article 28.

10.3 Data Protection Liability Allocation

Each party is independently responsible for its own compliance with applicable data protection law. In particular:

• Publishers are solely responsible for GDPR and ePrivacy compliance in respect of their own websites and data collection practices
• AdPriva is responsible for its own data processing as described in the Privacy Policy

No provision of these Terms transfers or allocates data protection regulatory liability from one party to another beyond what is required by mandatory applicable law.

11. Blockchain Anchoring (Paused)

11.1 Immutability

You acknowledge that blockchain transactions — including proof anchoring — are irreversible once confirmed. AdPriva cannot reverse, cancel, or modify on-chain transactions.

11.2 Anchoring Contract Risk

AdPriva's anchoring contract followed an event-only design: it recorded sealed Proof hashes on-chain and held no user funds. No smart contract can be guaranteed entirely free of bugs or vulnerabilities. AdPriva is not liable for losses arising from anchoring-contract vulnerabilities not present in the audited version of the contract.

11.3 Network Fees

Anchoring transactions incurred network fees (gas). AdPriva's backend paid the gas for proof anchoring; publishers and visitors incurred no on-chain fees, and none are due now because no new anchors are written.

11.4 No Control Over Blockchain

AdPriva does not control the Horizen blockchain or any other public blockchain network. Network outages, forks, or changes to the blockchain protocol are outside AdPriva's control and may affect the Services.

12. Fees and Payment

12.1 Publisher Fees

Access to the Services is charged on a subscription or usage basis as set out in the Publisher Agreement or Console configuration. AdPriva does not share revenue with publishers or make payments to website visitors.

12.2 Payment Terms

• Invoices are issued monthly unless otherwise agreed
• Payment is due within 10 days of invoice date
• Late payments accrue interest at the statutory rate under Portuguese commercial law
• AdPriva reserves the right to suspend services for non-payment after 15 days' notice

12.3 Disputed Invoices

Disputes must be raised in writing within 30 days of the invoice date. Undisputed portions remain due and payable. AdPriva will investigate disputes in good faith and respond within 15 business days.

12.4 Taxes

All fees are exclusive of VAT and applicable taxes. You are responsible for all taxes applicable to your use of the Services in your jurisdiction.

13. Term and Termination

13.1 Term

These Terms commence on the date you first access or use the Services and continue until terminated.

13.2 Termination by You

You may terminate your account at any time by using the account deletion function in the Console, or by contacting hello@adpriva.com with a written termination request.

13.3 Termination by AdPriva

AdPriva may suspend or terminate your account immediately and without notice if: you breach these Terms or any supplemental agreement; your account is used for fraudulent or illegal activity; you fail to pay amounts due after notice; or we are required to do so by law or court order. AdPriva may also terminate the Services generally with 30 days' written notice.

13.4 Effect of Termination

Upon termination: your licence to use the Services ends immediately; publishers must remove the AdPriva Tag from all properties within 7 days; Proofs and Consent Certificates already anchored on-chain remain publicly verifiable through the Explorer; and provisions that by their nature survive termination shall continue.

14. Disclaimers and Warranties

14.1 As-Is Basis

14.2 No Guarantee of Specific Verdicts

AdPriva does not guarantee any particular Verdict outcome, detection rate, or that every bot or fraudulent interaction will be identified. Traffic below the confidence threshold is flagged as uncertain rather than guessed. Verdicts depend on the signals available, model accuracy, and evolving fraud techniques.

14.3 Beta Features

Certain features may be designated as "beta" or "preview". These are provided without warranty and may be modified or discontinued at any time without notice.

15. Limitation of Liability

• Notify registered users via in-app notification or email at least 30 days before changes take effect
