RTBCookie Policy
Last updated: October 20, 2026
This Cookie Policy explains how NEMESIDA SMART DATA LTD (HE 465547), operator of RTBNest ("we", "us"), uses cookies and similar technologies on rtbnest.com and when delivering ads through our exchange. It should be read together with our Privacy Policy.
1. What are cookies?
Cookies are small text files stored on your device by your browser. Similar technologies include pixels (web beacons), local storage and device identifiers. They allow a service to recognise a device, remember settings and measure activity.
2. Cookies on rtbnest.com
Our corporate website does not use advertising or analytics cookies. We may set only strictly necessary cookies if needed for security or to load the site correctly. These do not require consent.
3. Cookies used in ad serving
When ads or Smart Links are delivered through our exchange on partner websites, we and our partners may use cookies and similar technologies for the following purposes:
| Category | Purpose | Typical lifetime |
|---|---|---|
| Strictly necessary | Routing requests, load balancing, security and preventing duplicate or fraudulent clicks | Session to 24 hours |
| Frequency capping | Limiting how often the same ad or Popunder is shown to a device | Up to 30 days |
| Measurement | Counting impressions and clicks, attributing conversions and reporting to partners | Up to 30 days |
| Advertising | Selecting relevant ads and offers based on device, location and previous interactions, where consent is given | Up to 90 days |
Demand partners that win an auction may set their own cookies or pixels when their ad is displayed. Their use is governed by their own privacy and cookie policies.
4. Consent
Where the law requires consent (for example in the EEA and the UK), the publisher of the website you visit is responsible for collecting it through its consent management platform. We read standard signals such as IAB TCF and GPP strings and adjust processing accordingly, for example by not setting non-essential cookies when consent is absent.
5. How to manage cookies
- Use the consent settings on the website you are visiting to accept or reject cookies;
- Block or delete cookies in your browser settings. Most browsers let you block third-party cookies;
- Enable Global Privacy Control (GPC) in your browser;
- On mobile devices, reset or limit your advertising ID in the device's privacy settings.
Blocking cookies does not stop ads from being shown, but the ads may be less relevant and frequency capping may not work.
6. Changes
We may update this Cookie Policy from time to time. The "Last updated" date shows the latest revision.
