Privacy

Two small cookies, both set only when you change something: opm_locale remembers whether you are reading in English or Indonesian, and opm_tz remembers which time zone event times should be shown in. They hold nothing but that choice, and the site works without them — you would simply be asked again each visit.

Two things stay in your browser and are never sent anywhere: the tier lists you build in the Tier List Maker, including any presets you save, and where you had scrolled to on a page so that going back returns you to the same place. Clearing your browser data removes both, and nobody else can read them.

The site loads Google Analytics to count visits and see which pages get used. It records things like the page you are on, roughly where in the world you are, and what kind of device and browser you have. It sets its own cookies to tell one visit from another.

This is used to decide what to work on next, nothing else. No profile is built about you, and nothing is sold or shared for advertising. If you would rather not be counted, a tracker blocker or Google's own opt-out add-on will stop it, and the rest of the site carries on working normally.

The site runs on a rented virtual server, which keeps ordinary server logs — the requests made, the addresses they came from — for a short period as any web host does. Cloudflare sits in front of it and sees those same requests. Its data lives in a Turso database. Analytics is Google's, as above.

The private admin area at /backoffice sits behind a sign-in and is for the people who maintain the handbook. It uses Cloudflare Turnstile to keep automated sign-in attempts out. Visitors to the public pages never touch either.

Each game has a public chat room. What you write there is stored and shown to everyone who opens that page, together with whatever name you typed in — so pick a name you are content for strangers to see, and keep anything private out of the message itself. The name is remembered in your own browser so you do not have to type it again.

Your address is not stored. A one-way hash of it is, so the room can tell that the same person is posting again and slow down a flood, and so somebody moderating can act on a repeat. The hash cannot be turned back into an address.

Before a message appears it is checked against a word list here and by OpenAI's moderation endpoint, which means the text of that message is sent to OpenAI for the check. The assistant behind the chat button also sends your question to OpenAI to answer it. Neither sends your name or your address.

There are no visitor accounts, so there is no name, email address, password or profile attached to reading this site. Nothing is asked of you, nothing is sold, and no data is handed to advertisers.

The game codes and numbers you type into the calculators are worked out in your browser as you type. They are not sent to the server and not stored.

Clearing cookies and site data in your browser removes everything this site has put there, including saved tier lists. Blocking analytics is up to you and costs you nothing here.

Because no account exists, there is no profile of you to request or delete. A message you posted in a chat room is the one thing here that is yours: say which one and it will be taken down.

This is a game handbook, not a service that collects personal details, and it is not directed at children specifically. Nothing here asks anyone for personal information.

If what the site stores changes, this page changes with it and the date at the top moves. It is worth a glance if you are returning after a long gap.
