A plain list of everything Rivetnest writes to your browser, and how to remove it.
A cookie is a small file a site saves in your browser so it can remember something between page loads. Rivetnest also uses local storage, which works the same way from your point of view but is not sent with every request. This page covers both, because the distinction matters less than what is actually being kept.
Three items are always stored once you interact with the site. The first records that you confirmed you are 19 or over, so the age gate does not reappear on every page. The second records your answer to the cookie banner, so we do not ask again. The third holds your Poseidon Era point balance and last bet size, which is what lets you close the tab and come back to the same game state. None of these are shared with anyone, and none can identify you personally.
If you choose Accept all, analytics cookies are added. They tell us how many people opened a page, which sections were read, roughly which region visitors came from and what browser they used. The data arrives grouped, not per person, and we use it to decide what to improve. Choose Necessary only and these are never set.
There are no advertising cookies on Rivetnest, no retargeting pixels, no social network trackers and no data brokers. Since there is nothing to sell you, there is nothing to advertise back at you.
Your choice can be reversed at any time by clearing site data for rivetnest.com in your browser settings. The cookie banner will appear again on your next visit and you can answer differently. Note that clearing data also removes your age confirmation and resets your point balance to the starting amount, which costs you nothing.
Every major browser lets you block or delete cookies for individual sites, and most offer a setting to refuse third-party cookies entirely. Blocking necessary storage will not break the game, but the age gate will appear on each page and your balance will restart every time. Questions about this policy can be sent to support@rivetnest.com.
Because the age confirmation and the point balance sit in browser storage, they stay on the machine rather than travelling with you. On a shared laptop the next person opens the site without the age gate appearing, and they see whatever balance was left behind. That is a limitation of storing things locally rather than a bug. If the device is not yours alone, clear site data when you finish or play in a private window, which forgets everything the moment you close it.
Local storage has no expiry date of its own, so the age confirmation, the cookie choice and the balance stay until you clear them or the browser clears space. Analytics cookies, when accepted, expire on their own within a year. Nothing here is refreshed silently to extend its life.
