Cookie Policy
Last updated: October 8, 2026
This Cookie Policy explains how PromoNinja ("we", "us", "our") uses cookies and similar technologies when you visit our website at www.promoninja.com.mx (the "Site"). It complements our Privacy Policy, which describes how we process your personal data more generally.
What are cookies and similar technologies?
Cookies are small text files that a website stores on your device when you visit it. They let the website recognise your device, remember your preferences and understand how the site is used.
Local storage and session storage are areas in your browser where a website can save information, much like cookies, but with no expiry date (local storage) or until the tab is closed (session storage). We use them to keep preferences and the state of what you were doing on the page.
IndexedDB is a small database inside your browser. Some of our services (for example, login and push notifications) use it to store technical data.
In this Policy, "cookies" refers to all of these technologies unless we say otherwise.
Who sets them?
- First-party cookies are set by PromoNinja itself.
- Third-party cookies are set by partners whose services we embed on the Site, such as Google (sign-in, analytics and advertising) and Meta (advertising measurement). These partners process your data under their own privacy policies, linked below.
How we classify cookies
We group cookies into three categories. The consent banner shown on your first visit lets you accept or refuse each category except "Necessary".
| Category | Purpose | Needs your consent? |
|---|---|---|
| Necessary | Required for the Site to work: keeping you signed in, remembering your preferences, preventing abuse and attributing deal referrals to our partners. Without them core features break. | No |
| Statistics | Help us understand how visitors use the Site (pages visited, features used) so we can improve them. Data is aggregated or pseudonymous. | Yes |
| Marketing | Used to show relevant advertising, limit how often you see an ad and measure the performance of advertising campaigns. | Yes |
