Cookie Policy
Last updated: 28 September 2026
In short: no tracking, advertising or analytics cookies. The Big Tom Dev website and every app apart from Hearthvale set no cookies at all. Hearthvale sets two cookies that are strictly necessary for logging in, so there's no cookie banner to click through.
What cookies are
Cookies are small files a website stores in your browser. Under the UK Privacy and Electronic Communications Regulations (PECR), sites need your consent for cookies, except those strictly necessary to provide a service you've asked for. Everything we use falls into that exception.
The Big Tom Dev website
The home page, The Big 7 and the legal pages set no cookies and use no local storage.
OmniPrice
OmniPrice sets no cookies. What you compare is kept only in the page address.
| Name | Purpose | Duration | Type |
|---|---|---|---|
omniprice.currency | Remembers the currency you chose under “Prices in”. Only set if you choose one. | Until you choose “Original currencies” or clear your browser data | Local storage · strictly necessary for a feature you asked for · never used for tracking |
Homebase
Homebase sets no cookies. Because it's a start page that works without an account, it keeps your setup in your browser's own storage. That's strictly necessary for the page to remember what you set up, and nothing in it is sent to us.
| Name | Purpose | Duration | Type |
|---|---|---|---|
homebase.v1 | Your theme, layout, widgets and their contents (notes, to-dos, links) | Until you reset Homebase or clear your browser data | Local storage · strictly necessary |
homebase.wx.* | A copy of the latest weather forecast, so new tabs don't refetch it | Replaced after 20 minutes | Local storage · strictly necessary |
homebase database | Photos you add as a background or in a photo widget | Until you remove them or reset Homebase | IndexedDB · strictly necessary |
Cardhouse
Cardhouse sets no cookies. It keeps one item in your browser's session storage so you can get back to your seat if the page reloads. That's strictly necessary for the game you joined.
| Name | Purpose | Duration | Type |
|---|---|---|---|
cardhouse:seat | Your table code and a random seat token, so you can rejoin your seat | Until you leave the table or close the tab | Session storage · strictly necessary |
Loopline, Pixelforge and Orbit Lab
None of these set cookies. Loopline and Pixelforge keep your work in your browser's local storage so it's still there when you come back. That's strictly necessary for the tool you're using, and nothing in it is sent to us. Orbit Lab stores nothing.
| Name | Purpose | Duration | Type |
|---|---|---|---|
loopline.v1 | Your latest beat | Until you clear your browser data | Local storage · strictly necessary |
pixelforge.v1 | Your current drawing and its frames | Until you clear your browser data | Local storage · strictly necessary |
Hearthvale
| Name | Purpose | Duration | Type |
|---|---|---|---|
hv_session | Keeps you logged in. It holds a random identifier; the server stores only a one-way hash of it. | 14 days, or until you log out | Strictly necessary · first-party · HttpOnly, Secure, SameSite=Lax |
hv_oauth_state | Protects the “Log in with Discord” step against forged login attempts (CSRF) | 10 minutes, deleted after login | Strictly necessary · first-party · HttpOnly, Secure, SameSite=Lax |
Hearthvale doesn't use local storage or any similar browser storage. Your character and settings are saved on our server, linked to your account. If you allow microphone access, your browser remembers that choice itself. You can change it in your browser's site settings.
Discord
When you click “Log in with Discord”, you go to discord.com, which sets its own cookies under Discord's policies. We don't control those.
Managing cookies
You can delete or block cookies in your browser settings. If you block Hearthvale's cookies, you won't be able to log in. Logging out removes hv_session.
