What this covers

This policy covers our websites, sungtech.io and livestreamautomixer.com, and it covers LiveStream AutoMixer ("LAM"), our Mac app. It is part of our Terms of Service, and it carries a version identifier and a permanent address for the same reason the terms do: so you can always read the version that applied to you.

SungTech LLC builds software and training for creators and communicators.

What we collect

When you email us. We receive your email address and whatever you choose to share, so that we can respond.

When you join the waitlist. We collect the email address you give us, and your name and organization if you provide them, so we can email you about the launch and about LAM. Every one of those emails has an unsubscribe link, and we stop when you use it.

When you buy a license. Purchases are handled by Link, a Stripe service, acting as merchant of record. Link collects the payment and billing details needed to complete the sale under its own privacy policy. We receive your name, organization, and email so we can issue your license and support you, along with a record that you accepted our terms and when. We never see your card number.

When you accept our terms. We keep a record of each acceptance — when it happened and which version of the terms was in force at that moment — because we're required to be able to show it, and because you're entitled to know what you agreed to. When you accept in LAM, it sends us a record of it: your license ID; which version you accepted, and when; details that show exactly what you were shown; when LAM first showed you the update; the version you'd accepted before; whether a deadline to accept had passed; your LAM version; whether you accepted when setting LAM up or after an update; and your name, if you typed one. If you're offline, it sends the record later.

Basic server logs. Like most websites, our hosting provider records standard technical information such as IP address and browser type, to keep the sites secure and running. We don't use it to identify you.

If you turn on LAM's crash reports. We receive the reports described below, along with the name, organization and email on your license.

That's it. We don't run advertising trackers, and we don't build profiles on visitors.

LiveStream AutoMixer

LAM runs entirely on your own Mac. This is the part people ask about most, so here it is plainly:

Your audio never leaves your computer. All mixing and processing happens locally. We do not receive, record, store, or have any access to your audio — not during a service, not afterward, not ever.

Logs and diagnostic files stay on your disk unless you choose to send them. LAM writes health logs, and can optionally record diagnostic data to help track down a problem. These are saved in your own home folder. If you want our help with an issue, you choose whether to send them to us. If you turn on crash reports, each report includes the most recent part of the health log, as described below.

No analytics, no tracking. LAM does not report how you use it, what you mix, or when you run it. The one exception is crash reports, if you turn them on: each one shows what LAM was doing shortly before the problem (see below).

License checks. To confirm your subscription is active, and to check for updates, LAM periodically contacts our licensing provider. It sends your license key and an identifier for the computer it's installed on, plus the Mac's model when LAM is first set up on it. That's all it sends our licensing provider. It sends no audio, no file names, and no personal content. LAM also checks sungtech.io for the current version of our terms, and sends us a record when someone accepts them. LAM keeps a signed offline license so it continues to work when the internet doesn't.

Crash reports, only if you say yes

LAM asks you once whether it may send us a report if part of it crashes or stops unexpectedly. Your audio keeps running while LAM asks, and LAM sends nothing unless you say yes. You can change your answer any time with Help → Send Crash Reports to SungTech.

What a report contains. What went wrong, such as an error message or the kind of crash, and how often and when. Your LAM version, and your Mac's model, processor, memory and macOS version. The most recent part of LAM's health log, which records what LAM was doing: for example, when output started and stopped, and each channel's type and levels. For a crash, the crash details your Mac records automatically.

Reports aren't anonymous. Each report carries an ID that links it to your license (not your license key). When a report arrives, we look up the name, organization and email on that license and keep them with the report, so we know whose it is and can contact you about it.

What we keep out of a report. A report never includes audio, and LAM's log doesn't record channel, profile or file names. Before a report leaves your Mac, LAM is built to take out your audio devices' names and ID numbers (such as serial numbers), your Mac's name and the IDs macOS gives it, your account name and your own name, email addresses, license keys, and your home folder's name. If we find anything like that in a report, we delete it.

When reports are sent. LAM sends reports in the background while your audio keeps running, and it never sends more than ten a day. Any report LAM can't send within 30 days is deleted from your Mac the next time LAM runs.

What we do with them. When a report arrives, we get an email (at most one a day for each license) with the name, organization and email on the license, what failed, and your LAM version and Mac details. We read reports, sometimes with the help of an AI assistant, only to find and fix problems in LAM. We keep reports for 90 days and delete our working copies once the problem is fixed. We never sell them.

How we use it

Only to reply to you, to issue and support your license, to email you about the product if you asked us to, to find and fix problems in LAM from crash reports you've turned on, to keep the sites working and secure, and to understand at a high level how the sites are doing.

We never sell or rent your information. We don't share it either, except with the service providers that help us run the business — our hosting and email providers, Link and Stripe for payments, our licensing provider, and the AI assistant we use in our work, including to help read crash reports — or where the law requires it.

How long we keep it

Records of your acceptance of our terms, and of your purchase, we keep for at least three years, because the law requires us to be able to produce them. Waitlist addresses we keep until you unsubscribe. Support emails we keep as long as they're useful for supporting you. Crash reports we keep for 90 days from when we receive them, and we delete our working copies once the problem is fixed. The email that tells us a report has arrived is kept with our support emails. Server logs are kept briefly by our hosting provider on their normal schedule.

Your choices

You can email us any time to ask what we hold about you, to correct it, or to have it deleted, and we'll do our best to honor reasonable requests promptly. You can unsubscribe from our emails using the link in any of them. You can turn LAM's crash reports on or off any time with Help → Send Crash Reports to SungTech. Turning them off deletes any reports LAM hasn't sent yet; to have us delete ones we've already received, email us.

If you ask Link to delete your data, Link will do so on its side, which may also cancel a subscription bought through it.

Changes

We'll give each update a new version identifier and change the "last updated" date above. The version we're replacing stays available at its own permanent address. If a change is material, we'll email current subscribers before it takes effect.
