Cookies & similar technologies

This page lists every cookie, localStorage key and similar technology SENTINEL Trader may set on your device. We apply Quebec's Loi 25 and the EU ePrivacy Directive: nothing other than strictly necessary technologies fires before you give us consent, and refusal is exactly as easy as acceptance.

What we explicitly do NOT use

We refuse to embed: Google Analytics with default settings, Meta / Facebook Pixel, TikTok Pixel, advertising-network trackers, third-party cross-site tracking cookies, or session-replay tools that record raw input. If you ever see one in DevTools while using the trader app, write to privacy@sentinel-os.ca — it is a bug we will fix.

Withdrawing consent

Withdrawing consent is exactly as easy as giving it. Open the Cookie preferences from the footer at any time, flip the categories you no longer want, and save. Your previous choices are overwritten and any optional cookies in those categories stop firing on the next page load.
