COOKIE POLICY
Last updated: July 3, 2026. This policy explains what cookies are and how we use them.
1. What Are Cookies?
Cookies are small text files that are placed on your device (computer, tablet, or mobile) when you visit a website. They are widely used to make websites work efficiently, to remember your preferences, and to provide information to website owners about how visitors use their site.
Cookies are not programs and cannot execute code on your device. They cannot carry viruses or install malware. Each cookie is unique to your browser and contains anonymous information such as a unique identifier, the website domain, and some digits and numbers.
2. Why We Use Cookies
Devception uses cookies for the following purposes:
- Essential functionality: To keep you logged in and maintain your session securely
- Security: To prevent cross-site request forgery (CSRF) attacks
- Advertising: To serve relevant advertisements through Google AdSense
3. Types of Cookies We Use
3.1 Essential Cookies
These cookies are strictly necessary for the website to function. Without them, you cannot log in or use the game. You cannot opt out of essential cookies.

3.2 Analytics Cookies
We do not currently use any analytics cookies. Devception does not run Google Analytics or any similar analytics service today — usage information comes only from anonymised server logs. If we adopt an analytics service in the future, we will list its cookies here and update the date at the top of this policy before it goes live.
3.3 Advertising Cookies (Google AdSense)
We use Google AdSense to display advertisements. AdSense uses cookies and similar technologies to serve ads based on your prior visits to our site and other sites across the internet. These cookies help make advertising more relevant to you.
You may opt out of personalised advertising by visiting Google Ads Settings or aboutads.info opt-out. Opting out means you will still see advertisements, but they will not be personalised to your interests.

4. How to Manage Cookies
You can control and manage cookies in various ways. Most web browsers automatically accept cookies, but you can modify your browser settings to decline cookies if you prefer.
