COOKIES, PLAINLY

Cookie policy

Effective September 10, 2026. ChessReign is operated by Nyza Creations LLC. This page explains what chessreign.com stores on your device and what choices you have; it supplements our privacy policy.

Strictly necessary

These keep the service working and are exempt from consent:

• cr_session — set by ChessReign; keeps you signed in, for guests as well as members. Cleared when you sign out.
• __cf_bm — set by Cloudflare, our edge network, to tell people from bots. Expires within 30 minutes of inactivity.
• chessreign.preferences, chessreign.practice, chessreign.training (local storage) — your board preferences, practice positions and training progress on this device.
• chessreign:cookie-consent (local storage) — remembers whether you accepted or rejected analytics, so we do not ask on every visit. 12 months.

Analytics — off until you accept

We use Google Analytics 4 to see, in aggregate, which lessons and puzzles get used and where people drop off. It is the only optional category we use, it never feeds advertising, and it is opt-in everywhere, not only where the law requires it: the Google tag is not loaded until you choose "Accept analytics" in the banner, and Google Consent Mode v2 stays denied for every storage type until then. There are no pre-ticked boxes, and "Reject" is exactly as prominent as "Accept". A decision is remembered for 12 months, after which we ask again.

• _ga, _ga_<stream-id> — set by Google Analytics 4 only after you accept; distinguish visitors and sessions for aggregate statistics. Two years.

What we do not do

• No advertising cookies (no Google Ads, Meta/Facebook Pixel, TikTok Pixel or equivalents).
• No cross-site behavioural tracking and no device fingerprinting.
• No selling or sharing of personal information through cookies.

How to change your mind

The button below, or Cookie preferences in the menu, opens the same panel and takes effect immediately. Withdrawing analytics also deletes the Google Analytics cookies already on your device.

Manage cookie preferences

You can also block or delete cookies in your browser settings. Blocking the strictly necessary cookie signs you out.

Global Privacy Control

If your browser sends a Global Privacy Control signal we treat it as a binding opt-out: we do not show the banner, analytics stays off, any Google Analytics cookies already on your device are deleted, and we tell you on screen that the signal was honoured.

Changes and contact

When this policy changes we update the date at the top. Questions: [email protected].
