Privacy Policy

MythicSim collects as little as it can, uses it to run your sims and keep your account working, and shares it only with the services that make the site run. We do not sell your data and we do not share it with anyone for marketing.

This policy covers the MythicSim website (mythicsim.com and its Chinese language mirrors), the MythicSim Discord bot, and the MythicSim in-game addon (together, the "Service"). MythicSim is operated by an individual developer based in Victoria, Australia.

You can use most of the site without signing in. When you submit a sim we store the /simc string you pasted and the results SimulationCraft produces. A /simc string contains your character name, realm, region, and the gear, talents and profession data the addon exported. It does not contain your Battle.net login or any payment details.

Every sim result has a URL. Anyone who has that URL can open it. Do not share a result link if you do not want the character on it to be seen.

We keep sim inputs and results so result links keep working. We may delete old sims at any time to free space, and we do not currently promise a fixed retention window.

You can sign in with Discord, Battle.net, or Google. We never see your password for any of these. What we store depends on the provider:

• ›Discord: your Discord user id and username. This is what links Discord bot commands to your account.
• ›Battle.net: your Battle.net account id and BattleTag. During sign-in we also read the list of World of Warcraft characters on your account (name, realm, class, level, and for max-level characters the active spec, item level and last login) so the sim form can offer them as one-click targets. We do not keep the Battle.net access token after sign-in finishes.
• ›Google: your Google account id and email address. The email is used to identify you when you report a problem and for nothing else. We do not send marketing email.

Sims you run while signed in are attached to your account so they show up on your history page. A session cookie keeps you signed in for 30 days of inactivity.

When a server invites the MythicSim bot, the bot only reads the slash commands sent to it. It does not read or store other chat messages.

Guild features (roster sims, loot ranking, enchant checks, group sessions) store the character names, realms and regions that a server member adds, the Discord id of whoever added them, and the sim results for those characters. Character gear and talents for these features are read from Blizzard's public Armory API.

The addon runs on your machine and only sends data when you paste its output into the site or link it to your account. When you link it, we store a hashed pairing token and a character label so your account page can show which addon is connected. We never store the token itself.

We use two analytics tools to understand how the site is used and which features are worth building:

• ›Google Analytics 4 sets cookies (for example _ga) to count visits and pages viewed. Google processes this data under its own privacy policy.
• ›PostHog records page views and clicks so we can see where people get stuck. Session replay is disabled. Anonymous visitors are not profiled; once you sign in, events are tied to your account id so we can debug problems you report.

Beyond these, the site sets a cookie to remember your language choice and a session cookie when you sign in. Preferences such as your last used fight style are kept in your browser's local storage and never leave your device unless you run a sim.

You can block analytics cookies with your browser or an extension. The site keeps working without them.

Some content pages (rankings, guides and tier lists) may show ads served through Grow by Mediavine and its partners. Ad partners may set their own cookies and use your IP address and browsing activity on the page to choose which ads to show. Where the law requires it, a consent banner lets you refuse this before any ad cookies are set.

Ads are never shown on sim submission or result pages, and ad partners do not receive your /simc string or sim results.

Mediavine's privacy policy is at https://www.mediavine.com/privacy-policy/. You can opt out of interest-based ads through your browser settings or at https://optout.aboutads.info/.

Our hosting providers (Vercel and Cloudflare) log the IP address, browser and requested page for every request. We use the IP address to rate limit sim submissions and problem reports, and to block abuse. We do not use it to identify you. Logs are kept for a short period by those providers and then discarded.

Pages such as the top players rankings show character names and performance figures that are already public on Warcraft Logs and Blizzard's Armory. This is game data about characters, not data about MythicSim users. If a character you control appears there and you want it removed, contact us and we will exclude it.

We share data only with services that run the Service on our behalf:

• ›Vercel (website hosting) and Cloudflare (network, DNS and tunnelling).
• ›Neon (database) and self-hosted storage for sim inputs and results.
• ›Discord, Blizzard Entertainment and Google as sign-in providers.
• ›Google Analytics and PostHog for analytics.
• ›Grow by Mediavine and its partners for advertising on content pages.
• ›Stripe for payments, once paid tiers are live. Card details go to Stripe directly and never touch our servers.

Sim workers run in Australia. Hosted services listed above run in the United States and elsewhere, so your data may be transferred outside the country you live in. Where GDPR applies, those transfers rely on the provider's standard contractual clauses or on the transfer being necessary to provide the Service you asked for.

We may disclose data if the law requires it, or transfer it as part of a sale or handover of the Service. We will note any such change here.

• ›Account data: for as long as you have an account.
• ›Sims and results: until we prune them. There is no fixed window today.
• ›Guild rosters and sessions: until the server that created them removes them or the bot is removed from the server.
• ›Analytics: per the retention settings of Google Analytics and PostHog, then aggregated or discarded.
• ›Access logs: a short period set by the hosting provider.

You can ask us to show you the data we hold on you, correct it, or delete your account and everything attached to it. Use the Report a problem link in the footer, or message us on Discord, and say which sign-in provider you used. We aim to respond within 30 days. Deleted data may persist in backups for up to 90 days.

If you live in the European Union, the United Kingdom or another region with a general data protection law, you also have the right to object to or restrict processing, to data portability, and to complain to your local data protection authority. We rely on our legitimate interest in running and improving the Service for analytics and abuse prevention, on your consent for advertising cookies, and on the need to provide the Service you requested for everything else.

All traffic to the site uses HTTPS. Sign-in goes through the provider's own OAuth flow so we never handle passwords. Addon pairing tokens are stored hashed. No system is perfectly secure; if you believe your data has been exposed, contact us and we will investigate.

The Service is not directed at children under 13 and we do not knowingly collect their data. If you believe a child under 13 has an account, contact us and we will remove it.

Use the Report a problem link at the bottom of any page, or join the MythicSim Discord server linked in the header. Either reaches the developer directly.
