Privacy Policy
This Privacy Policy explains how Missroot (“we”, “us”, “our”) handles information when you play I Only Moved My Mouse (the “Game”) on Steam. The short version is that we do not handle any. The Game plays entirely offline, keeps your progress in one file on your own machine, has no account, no sign-in, and no way of sending anything to us. The rest of this page spells that out.
1. Summary
- The Game never connects to us. It has no network code of its own and no account to sign in to.
- Everything it remembers lives in one save file on your machine (section 2). We cannot see it.
- No analytics, no advertising, no crash reporting, no tracking, and nothing to sell or share — we hold no personal information about you at all.
- The only companies that touch anything are Valve, which runs Steam, and Cloudflare, which serves this website (section 4).
2. What stays on your device
The Game writes one file to your own machine, and we do not see any of it:
- The save record (
save.json) — your shard bank, the sword’s tier, forge levels, embers and ascension count, best wave, run and kill counts, the best shards-per-second pace you ever reached (what offline earnings are paid from), and the time the Game last saw you. - Settings — music and sound volume, screen shake, and auto-cut. These are kept in the same file.
The “last seen” time is a clock reading taken from your own machine when the Game saves. It exists only so the next launch can work out how long the blade kept cutting while you were away. It is compared on your machine and never leaves it.
If you enable Steam Cloud, Valve may copy save.json between
your machines. That copy is between you and Steam under
Valve’s Privacy Policy;
it does not pass through us.
3. What we never collect
- No analytics, telemetry, crash reporting, or advertising SDKs in the Game.
- No account, email address, name, Steam ID, or IP address — the Game has nowhere to send them.
- No advertising identifiers and no cross-app or cross-site tracking.
- No location, contacts, photos, microphone, or camera.
- No payment details — the purchase is handled by Steam, and we never see your card.
- We do not sell personal information, and we do not “share” it for cross-context behavioural advertising as those terms are used in California law. We have none to sell or share.
4. Who else is involved
We are based in South Korea. Because the Game sends us nothing, no data about you is transferred to us or stored on our behalf anywhere. The companies that do handle something, and nobody else:
- Valve Corporation — runs Steam on its own account: selling and installing the Game and, if you enable it, Steam Cloud. What it collects is governed by the Steam Privacy Policy.
- Cloudflare, Inc. — serves this website. Reading this page leaves the ordinary web-server traces of a request with it, under the Cloudflare Privacy Policy. This website itself sets no cookies and runs no analytics.
5. Your rights
Depending on where you live, you may have the right to access, correct, port, or delete personal information a company holds about you, and — in California — to know what is collected and to not be discriminated against for asking. We hold nothing, so every such request has the same answer: there is no record to return, correct, or erase. If you write to us anyway (section 9), the email you send is the only personal information we will ever have from you, and we keep it only as long as it takes to reply. If you are in the EEA or the UK you may also complain to your local data protection authority; in Korea, to the Personal Information Protection Commission.
6. Deleting your data
There is nothing on our side to delete. On your machine, delete the Game’s save folder (or uninstall the Game) to remove local progress — the paths are listed on the support page. If Steam Cloud is on for the Game, turn it off first, or Steam may put the file back.
7. Children
The Game is for a general audience and is not directed at children under 13, or under the higher age your own country sets — as much as 16 in parts of the EEA. It is sold only through Steam, whose Subscriber Agreement requires account holders to be at least 13. Since the Game collects no personal information from anyone, it collects none from children either.
8. Changes to this policy
If a future version adds anything that touches your data — cloud saves of our own, leaderboards, purchases, analytics, or Steam features that identify you — we will update this page with a new effective date before that version ships, and say so in the patch notes.
