Privacy policy

Who we are

MEW IO LLC (“Mew,” “we,” “us”) operates mew.io and develops Sixty and COUNTERCUT. We are based in San Francisco, California. For any question about this policy or about information we hold, write to justin@mew.io.

Sixty: game data

Sixty does not require an account, name, or email address to play. It stores your progress, scores, attempts, play time, and a randomly generated persistent player identifier on your device. The identifier lets us associate analytics and diagnostics from the same installation; it is not your name, but the associated records are not anonymous.

Gameplay analytics

Sixty uses Google Analytics for Firebase to record sessions, session duration, levels played, attempts, results, medals, completion times, personal bests, highest level attempted, and total play time. These events are associated with the player identifier. The SDK also collects app and device information, app-instance identifiers, usage information, and approximate location derived from network information. On iOS it uses the device vendor identifier when an advertising identifier is unavailable. The Android app removes advertising-ID permissions. We use this information to understand how people play and improve gameplay and reliability. See Google's data collection information.

Errors and performance

Sixty uses Sentry for crash and error reports, diagnostic logs, and sampled performance measurements. Reports can include error details, device and operating-system information, app version, and the same player identifier. We use them to diagnose problems and improve performance. Session replay is disabled. See Sentry's privacy policy.

Storage and your choices

Progress is saved locally. Resetting progress in the game does not delete your player identifier or records already sent to our providers. Removing the app's stored data removes local saves and identifiers; device backups may retain or restore them. Analytics and diagnostics are enabled automatically, and the current version has no in-app switch to disable them. To request access to or deletion of information we hold, contact justin@mew.io. We may need information to locate your installation's records, since Sixty has no account tied to your email address.

Analytics and diagnostic records are retained under the retention settings of our Google Analytics and Sentry projects for the purposes described above. Removing local data does not remove these records. Contact us for help with a deletion request.

COUNTERCUT: game data

COUNTERCUT, our virtual-reality rhythm game, does not collect, send, or share any personal information. It has no accounts, no sign-in, no online features, no analytics, no advertising, and no tracking. On Meta Quest it does not ask for permission to use the internet, so it cannot connect to it. We receive no information about you from playing it.

What the game uses while you play

To work at all, a virtual-reality game reads the position and movement of your headset and controllers, and the buttons you press. COUNTERCUT uses this only in your device's memory, in real time, to draw the game and judge your cuts. It is not recorded, stored, or sent anywhere. The game does not use your device's cameras, microphone, passthrough view, eye, face, or body tracking, location, or contacts.

What it keeps on your device

Your scores and progress for each level (your best, the scores of past runs, and a top-ten board that records the date of each run), your settings (such as the audio timing offset, the hand that holds the saber, seated or standing play, the STRICT and DETAILED modes, colour-blind mode, reduce flashes, and the volumes), and whether you have read the health and safety notice and been offered the tutorial. On a computer, the game engine also writes a log file for troubleshooting with the game's own messages and technical details of the computer; it holds no name or account information. All of it stays on your device and we have no access to it. Uninstalling the game, or clearing its data in your device's settings, deletes it. A backup your platform makes (such as Meta's cloud backup) is held by the platform under its own privacy policy.

The stores and platforms

You get COUNTERCUT through a store and play it on a platform: the Meta Horizon Store and Meta Horizon OS (Meta's Privacy Policy), and Steam (Valve's Privacy Policy Agreement). They handle your account, purchase, downloads, and, on some platforms, play time and crash reports, under their own policies. They may give us totals about sales and downloads and technical crash reports that do not identify you, which we use only to sell and fix the game.

Purchases in the game

COUNTERCUT may offer extra content to buy in the game, such as new albums of songs. You buy it through the store you got the game from (Steam or the Meta Horizon Store), which takes your payment and handles it under its own privacy policy. We never see your card or other payment details. The store tells the game what you own so it can unlock it, and gives us a record of each purchase (such as the item, the date, the price, an order number, and your store account ID). We use these records only to deliver what you bought, handle refunds and support requests, prevent fraud, and keep the accounts and tax records the law requires.

The COUNTERCUT website

The game's website, countercutgame.com, counts visits with Vercel Web Analytics and Google Analytics. Both record the pages viewed, the referring site, and the country, browser, operating system, and device type. Vercel Web Analytics sets no cookies. Google Analytics sets cookies that recognise a returning browser, except in the European Economic Area, the United Kingdom, and Switzerland, where it sets none and sends Google only measurements without cookies. Google's advertising features are off for the site, and we do not use either tool to identify you or follow you across other sites. Google processes this data under Google's Privacy Policy, and you can opt out of Google Analytics with Google's browser add-on or by blocking its cookies. The site itself keeps one setting in your browser's session storage for the length of your visit, so its opening animation plays only once; it holds nothing about you, is never sent anywhere, and is gone when you close the tab. Vercel also keeps ordinary request logs for security and reliability, as described below for this site.

COUNTERCUT is made for players aged 13 and over. To ask us anything about it, or to delete an email you sent us, use the contact form (“App support (COUNTERCUT)”) or email justin@mew.io.

What the website collects

There are only two ways information reaches us through this site.

Information you send us

If you fill in the contact form, we receive your name, email address, and message, plus your company name and the subject you selected if you provided them. We also use a hidden spam-trap field to reject automated submissions.

Ordinary technical information

Like every website, ours sits behind a hosting provider that records basic request information — IP address, browser and device type, the page requested, and the time — for security, abuse prevention, and reliability. These logs are generated automatically by our infrastructure provider, are kept for a short period, and are not used to identify or profile visitors.

What we do not do

• We do not sell, rent, or trade your information. Not to anyone, for any price.
• We do not run advertising, ad pixels, or cross-site tracking on this site.
• We do not set analytics or advertising cookies. This site sets no cookies at all.
• We do not add you to a mailing list because you contacted us. If we ever start a newsletter, you will have to ask for it.
• We do not use your message to train machine learning models.

How we use what you send

To answer you, to have the conversation that follows, and to keep a record of our correspondence the way any business keeps its email. If a conversation turns into an engagement, the information becomes part of our ordinary client records. That is the extent of it.

Who else touches it

We keep the list of service providers short, and each one processes information to provide its service:

• Cloudflare — hosts and delivers this website, and handles the request logging described above.
• SendGrid (Twilio) — carries contact form submissions to our inbox as email.
• Google Workspace — where our email lives once it arrives.
• Google Analytics for Firebase — processes Sixty gameplay analytics.
• Google Analytics — counts visits to countercutgame.com.
• Sentry — processes Sixty error reports, logs, and performance data.
• Vercel — hosts countercutgame.com and provides its cookieless Web Analytics.

Beyond those, we share information only when we genuinely have to: to comply with the law, to respond to a valid legal request, or to protect our rights or someone's safety. If MEW IO LLC were ever acquired or merged, information would transfer with the business, and this policy would continue to apply until you were told otherwise.

How long we keep website information

Contact messages stay in our email for as long as they are useful — typically a few years, because a conversation from two years ago often becomes relevant again. Server logs are short-lived and expire on our provider's schedule. You can shorten any of this by asking us to delete your information.

Your choices

Whatever privacy law applies where you live, our answer is the same and we are not going to make you prove your jurisdiction first. Email justin@mew.io and ask us to:

• tell you what we hold about you,
• send you a copy of it,
• correct anything that is wrong, or
• delete it.

We will respond within 30 days. We may need to confirm your identity and locate the relevant records before fulfilling a request. If we must retain information to meet a legal obligation, we will explain that. You will never be treated differently for asking.

Cookies

This site does not set cookies and does not use local storage or similar tracking technologies, and neither does countercutgame.com. There is no cookie banner because there is nothing to consent to.

Security

Sixty sends analytics and diagnostic data to Google and Sentry over encrypted HTTPS connections. Local game data remains in the app's device storage.

The site is served over HTTPS, and form submissions are encrypted in transit. We keep access to our inbox limited to the people who need it. No system is perfect, and we will not pretend otherwise, but we do not hold the kind of sensitive data that makes us an interesting target — and we would rather keep it that way, so please do not send passwords, payment details, or confidential documents through the contact form.

Children

This site is aimed at businesses and is not directed at children under 13. We do not knowingly collect information from them. If you believe a child has sent us something, email us and we will delete it.

People outside the United States

We are a US company and our providers process information in the United States. If you contact us from elsewhere, your information will be handled here. Our app service providers may also process information in other countries where they operate.

Changes

We update this policy on this page whenever this site or our games change what they collect or how they use it, for example when a game gains a feature that needs a new permission or a new kind of purchase. The date at the top shows when it last changed, and the version on this page is the one that applies. We do not send separate notice of changes, so please check this page from time to time. Where a new feature needs a permission on your device, your device or the store asks you for it before the feature can use it.
