Privacy

Updated October 12, 2026

Mutto doesn't sell, share or ask for personal data to work. There's no account, no ads and no tracking you around the web. This page says exactly what stays on your computer, what leaves it and why.

What stays on your computer

Your settings (shortcuts, sounds, rules, integrations) stay only on your computer, in the app's data folder. The date your free trial started is also kept in the Windows registry, so the trial doesn't restart if the folder is deleted. Your license key, once you activate one, lives in the same folder.

Mutto doesn't record or listen to your audio. It only turns the microphone mute in Windows on and off, and reads whether the microphone is muted, to show you the state.

Phone, Teams and Meet: all on your own network

• Phone. With the phone option turned on in Settings, Mutto opens a page on your local network, and the phone talks straight to the PC over Wi-Fi, without any server on the internet. Only someone who scanned the QR code, which carries a secret, can get in. Turn it off in Settings and the page closes.
• Teams. The integration uses Teams' own API, on your computer, to sync mute, camera, raised hand and leave. Nothing goes to our servers.
• Google Meet. The extension for Chrome and Edge reads, in the Meet tab, only the state of the microphone and camera buttons, and presses those buttons and the leave button. It only talks to Mutto on the same PC (at the local address 127.0.0.1). It doesn't read the meeting content, the participants or the chat, and sends nothing out.

When Mutto uses the internet

• Once a day, the app downloads from this site the number of the newest version and the list of deactivated license keys. Nothing about you goes along, only the app and Windows versions, like any browser sends. Updates come from the GitHub releases.
• With a key activated, when you activate it and at most once a week, the app sends the site the key and a number that identifies the computer without revealing which one it is (a fingerprint of the Windows identifier mixed with the key). The site answers whether the key is valid and keeps only a fingerprint of the key, that number and the first and last time it saw it, to know whether a key was shared. It doesn't keep your IP, email or computer name, and deletes what hasn't shown up in 90 days.
• During the free trial, the app sends the site the date the trial started and another number that identifies the computer without revealing which one it is. The site keeps only that number and the dates, so the trial doesn't restart when the app is reinstalled, and deletes what hasn't shown up in a year.
• Without internet, everything keeps working: the app uses the last answer it got.

Usage statistics: only with your “Yes”

Mutto doesn't send usage statistics. If it ever does, it will ask first, and with no answer or a “No”, nothing is sent.

Purchases

Payment happens on Stripe's page: your card goes straight to Stripe, and we never receive or store payment details. The site keeps the email and name Stripe reports, the license key issued, the amount, the language and the Stripe purchase ID, to email you the key, find your purchase if you ask for help and deactivate the key if the purchase is refunded or disputed. If the link that brought you to checkout had a campaign (like the links in our emails), the site notes that campaign with the purchase.

Emails

If you leave your email to buy, to try Mutto or to hear about the launch, it's kept to send you a few emails about Mutto: up to two reminders if the purchase isn't finished; during the trial, a welcome, tips and notices before and after it ends; and, for buyers, the key and two messages in the first weeks. Every one has an unsubscribe link that works with one click.

Emails go out through Resend, the sending service we use. Your email also goes to our list at Kit (ConvertKit), tagged with the stage you're in (trying, unfinished purchase, customer). News and launches go only to people who asked.

Site visits

The server itself counts how many times each page is opened, with no cookie and without keeping your IP: only the page, where you clicked from (from another site, only the domain), the link's campaign and the day. The pages also load Analisa, the visit statistics service run by Mutto's own developer, with no ad or tracking companies involved, which counts visits to each page, where they come from and the link's campaign.

The site only sets a cookie if you switch the language in the footer: the idioma cookie, to remember your choice.

Downloads

When you download Mutto (with the button, PowerShell or winget) or update from inside the app, the site notes the version, the platform, the way you used, the page you clicked from (from another site, only the domain) and the link's campaign. It doesn't keep your IP or anything that identifies you.
