Privacy Policy

NEMESIDA SMART DATA LTD (“we”, “us”, “our”) operates ad tracking and measurement services (the “Services”). Our domains are used as technical endpoints for safe redirects, ad performance analytics, fraud detection, and campaign verification. We are an ad tracking and analytics provider; we do not host media files, user-generated content, or sell products.

1. Scope of this policy

This Privacy Policy applies to data collected through our ad tracking domains, APIs, and pixels. It does not cover external websites or apps of our partners, advertisers, or publishers.

2. Data we collect

• Technical information: IP address, browser type, device type, language, referrer, operating system, and request timestamps.
• Ad event data: bid requests, clicks, conversions, redirect paths, campaign identifiers, and performance metrics.
• Geolocation: country and region inferred from IP, never precise GPS data.
• Fraud prevention data: pseudonymous identifiers, hashed values, and anti-fraud fingerprints used to detect invalid traffic (IVT).
• Cookies and local storage: in some cases, we set or read a unique cookie to maintain frequency capping or attribution IDs.

3. Purposes and legal bases for processing

We process data under the following bases defined by the GDPR:

• Legitimate interest (Art. 6(1)(f)) — measuring ad performance, preventing fraud, and ensuring security of systems.
• Legal obligation (Art. 6(1)(c)) — complying with applicable data protection and tax laws.
• Consent (Art. 6(1)(a)) — where partners obtain user consent for cookies or device identifiers, we rely on their consent strings (e.g. IAB TCF v2).

4. How we use the data

• To deliver and optimize advertising campaigns and attribution.
• To analyze campaign reach, conversion, and engagement statistics.
• To prevent invalid traffic, fraud, and abuse.
• To maintain operational logs and ensure reliability of services.
• To fulfill legal and regulatory obligations.

5. Data retention

We keep raw log data for a limited period, typically up to 13 months, for security and reporting purposes. Aggregated, non-identifiable statistical data may be stored longer for analytics or business continuity.

6. Data sharing and recipients

• Service providers (processors): cloud hosting, analytics, and data security partners under strict contractual agreements.
• Clients and partners: receive aggregated or pseudonymous reports related to their campaigns.
• Authorities: when required to comply with legal obligations or protect the rights and safety of our company or users.

7. International data transfers

We may transfer data outside the European Economic Area (EEA) under appropriate safeguards, such as Standard Contractual Clauses (SCCs), and ensure that equivalent protections apply to all transferred data.

8. Data security

We implement encryption, access controls, monitoring, and other security measures to protect personal data. Despite these efforts, no system is entirely secure, and we cannot guarantee absolute protection.

9. Your rights

Depending on your location, you may have the following rights:

• Access to your personal data;
• Rectification or erasure of data;
• Restriction or objection to processing;
• Data portability;
• Right to withdraw consent (where applicable).

To exercise your rights, contact info@nsdltd.com. We may ask for identification to verify your request.

10. Children’s privacy

We do not knowingly collect or process children’s data.

11. Updates to this policy

We may update this policy periodically to reflect legal, technical, or operational changes. Any major updates will be posted on this page with a revised “Last Updated” date.
