Terms of Service

Last updated: 28 September 2026

These terms apply to the Big Tom Dev website (bigtomdev.fyi), to Hearthvale (bigtomdev.fyi/hearthvale) , to OmniPrice (bigtomdev.fyi/omniprice), to Homebase (bigtomdev.fyi/homebase), to Cardhouse (bigtomdev.fyi/cardhouse) and to Loopline (bigtomdev.fyi/loopline), Pixelforge (bigtomdev.fyi/pixelforge) and Orbit Lab (bigtomdev.fyi/orbitlab). “We” and “us” means Big Tom Dev. By using Hearthvale (for example by logging in with Discord), or any of the other apps, you agree to these terms. Please also read the Privacy Policy.

1. About Hearthvale

Hearthvale is a free, independent hobby project that shows a Discord server as an explorable 3D world. It is not affiliated with, endorsed by or sponsored by Discord Inc. “Discord” is a trademark of Discord Inc.

2. Who can use it

• You must be at least 13, or the minimum age to use Discord where you live, if that's higher.
• You log in with your Discord account, so you must follow Discord's Terms of Service and Community Guidelines, and the rules of each server you visit.
• You're responsible for activity on your account. Log out on shared devices.

3. Acceptable use

Don't use Hearthvale to:

• harass, threaten, bully or impersonate anyone, or post hateful, sexually explicit or illegal content;
• spam, flood channels, or get around rate limits, bans, timeouts or channel permissions;
• record, stream or share other people's voices or messages without their consent;
• attack, overload, probe for weaknesses in or reverse-engineer the service, or access it with bots or scripts;
• break the law or anyone else's rights.

If you find a security problem, please tell us privately at hello@bigtomdev.fyi rather than exploiting it.

4. Your messages and voice

• Messages you send from the world are posted to real Discord channels under your name and avatar. They're public to that channel just as if you'd posted them in Discord. You're responsible for what you post. You keep any rights you have in your content, and you give us permission to transmit and display it as needed to run Hearthvale.
• Voice chat goes live to players near you. In a voice gazebo it is also relayed to the people in that Discord voice channel, and theirs to you. Speak as you would in the Discord call itself.
• Discord's moderation still applies. Server moderators can remove messages in Discord, and permissions and timeouts set in Discord are enforced in Hearthvale.

5. Server administrators

If you add the Hearthvale bot to a Discord server, you confirm you're allowed to, and you agree to tell your members that the server can be viewed as a Hearthvale world. That includes their recent public activity appearing to other members, and voice channels being relayed while a player is in a gazebo. You can remove the bot at any time. Hearthvale then stops showing that server.

6. OmniPrice

Information only: not financial advice

OmniPrice shows published prices and statistics for general information. Nothing on OmniPrice is financial, investment, tax or other professional advice, or a recommendation to buy or sell anything. Don't rely on it to make financial decisions. Check the original source, and get professional advice where appropriate.

Accuracy

Figures come from third parties and are shown as published. They can be delayed (many are monthly, some are released weeks later), revised by the publisher, incomplete or wrong. Currency rates are reference rates, not rates you can trade at. Prices shown in another currency are converted with those reference rates (the daily rate, or the average for the month or quarter), so they are approximations, and changes include exchange-rate moves. Stock prices, when available, are end-of-day closes, not live quotes.

Data sources and licences

Each chart names its source. OmniPrice uses:

• U.S. Bureau of Labor Statistics, U.S. Energy Information Administration and the Federal Reserve Board, via FRED®, Federal Reserve Bank of St. Louis. These are U.S. Government works in the public domain. FRED® is a registered trademark of the Federal Reserve Bank of St. Louis, which does not endorse OmniPrice.
• International Monetary Fund Primary Commodity Prices, via FRED®, used with attribution under the IMF's terms.
• OECD data, via FRED®, under CC BY 4.0.
• Office for National Statistics: contains public sector information licensed under the Open Government Licence v3.0.
• European Central Bank euro foreign exchange reference rates, via Frankfurter.
• CoinGecko: crypto prices, powered by CoinGecko.
• Twelve Data: stock and ETF prices, for personal, non-commercial viewing only.

ETF names such as the S&P 500®, Nasdaq-100® and Dow Jones Industrial Average are trademarks of their owners, who do not sponsor or endorse OmniPrice. OmniPrice shows ETFs that track these indices, not the indices themselves.

Using the data

You may view OmniPrice and share links and screenshots for personal, non-commercial purposes, keeping the source credits. Don't scrape, bulk-download or automate requests to OmniPrice or its API, or republish its data in bulk. If you want the data, go to the original providers, whose own licences apply.

7. Homebase

• Your data is yours, and it's on your device. Homebase stores everything in your browser. We can't see it, back it up or recover it. If you clear your browser data or reset Homebase, it's gone unless you downloaded a backup.
• Links, search and other sites. Quick links and searches take you to other websites, which have their own terms. We're not responsible for their content.
• Weather comes from Open-Meteo (CC BY 4.0). It's a forecast, so don't rely on it for safety-critical decisions. Currency and market widgets use OmniPrice data, and section 6 applies to them (it isn't financial advice).
• Photos you add must be ones you're allowed to use. They never leave your device.
• Browser guides describe other companies' browsers, whose menus change over time. Extensions they mention are made by third parties, so install them at your own discretion.
• Quotations shown in the quote widget are from works in the public domain.

8. Cardhouse

• Play money only. No real-money gambling. Cardhouse chips are free and have no monetary or other value. They can't be bought, sold, traded, transferred, cashed out or exchanged for prizes, and there is no way to pay us for them. Any attempt to buy, sell or trade chips or seats, including outside Cardhouse, breaks these terms.
• Age. You must be at least 13 to play.
• Fair play. Don't collude with other players, share your cards with another player at your table, use bots or scripts to play, or try to see cards or game data you aren't meant to. We may remove players or close tables that do.
• Nicknames must not be offensive, impersonate someone else, or include personal information.
• Tables are temporary. Chips and tables exist only while a table runs, and end if our server restarts. Chip counts aren't saved or restored.
• The rules used by each game are described in the game. Rules may be simplified compared with casino or tournament play, and the “nine-card poker” rules may change. If the software makes a mistake, results shown are final, as nothing of value is at stake.
• If you're worried about gambling, including with real money elsewhere, free and confidential support is available from GamCare (0808 8020 133).

9. Loopline, Pixelforge and Orbit Lab

• What you make is yours. Beats you make in Loopline and art you make in Pixelforge belong to you. We claim no rights in them, and you can use your exports however you like, including commercially.
• Your work lives on your device. We don't store or back up anything you make. Clearing your browser data deletes it, so export anything you want to keep.
• Sharing. You're responsible for what you share. Don't use these tools to make or share anything unlawful, or anything that infringes someone else's rights.
• Orbit Lab is a toy. Its physics is a simplified simulation for fun and learning, not a scientific model.
• Palette names such as PICO-8 and Game Boy describe the colours only. Those products belong to their owners, who don't sponsor or endorse Pixelforge.

10. Ownership

The code, art and design of the website and of every Big 7 app belong to Big Tom Dev, except what you make with them (section 9). You may use them for personal, non-commercial purposes under these terms. Discord names, avatars and server content belong to their respective owners. Data shown in OmniPrice belongs to, or is licensed by, the providers listed in section 6.

11. Availability and changes

Hearthvale is provided free, as a hobby project. It may be unavailable at times, change, or stop altogether, and features such as the voice bridge depend on Discord's services and could stop working if Discord changes them. We'll try to give notice of major changes. We may update these terms. If we do, we'll change the date above, and continuing to use Hearthvale means you accept the new terms.

12. Liability

The website and every app are provided “as is”, without any promise that it will be error-free or always available. We're not responsible for content posted by other users, for Discord's own services, or for any loss from decisions made using figures shown in OmniPrice.

Nothing in these terms limits liability that can't legally be limited, such as for death or personal injury caused by negligence, or for fraud. If you're a consumer, your statutory rights are not affected. Otherwise, as Hearthvale is free, our total liability to you is limited to £50.

13. Ending your use

You can stop at any time. Settings → Account → Delete my data erases your Hearthvale data and revokes its access to your Discord account. We may suspend or block access for anyone who breaks these terms or puts others or the service at risk.

14. Law and contact

These terms are governed by the law of England and Wales, and its courts have jurisdiction. If you live elsewhere in the UK, you may also bring proceedings in your local courts. Questions? Email hello@bigtomdev.fyi.
