This Cookie Policy explains what cookies are, which ones Signal Engine uses, and how you can control them. By using signalengine.solutions, you consent to our use of cookies as described in this policy.
01What are cookies?
Cookies are small text files placed on your device when you visit a website. They are widely used to make websites work efficiently, remember your preferences, and provide information to site owners about how visitors use their platform.
Cookies can be "session cookies" (deleted when you close your browser) or "persistent cookies" (which remain on your device for a set period or until you delete them). They can also be "first-party cookies" (set by Signal Engine directly) or "third-party cookies" (set by our service providers).
Similar technologies — such as local storage, pixels, and tracking scripts — function in comparable ways and are covered under this policy.
02Cookies we use
Signal Engine uses three categories of cookies: essential cookies required for the platform to function, analytics cookies that help us understand how visitors use our site, and marketing cookies that support our advertising efforts.
We do not sell cookie data to third parties. All data collected via cookies is used solely to operate, improve, and market Signal Engine in accordance with our Privacy Policy.
