Who this applies to

Harmonic is used by two kinds of accounts: a teacher, who manages their own roster of students, and a student account, which represents whoever manages a pupil's side of the relationship: usually a parent or guardian, or the student themselves if they're old enough to manage their own account. There is no separate "guardian" account type; a parent/guardian and an independent student both sign in the same way.

Information we collect

From Sign in with Apple, if you sign in that way: your name, the first time you sign in only (Apple doesn't send it again on later sign-ins), and Apple's unique, anonymous identifier for your Apple ID, which becomes your account's internal ID. We don't ask Apple for your email address, so we never receive it. You can change your name at any time in Settings, under Profile.

From Sign in with Google, if you sign in that way: your name, and Google's unique identifier for your Google Account, which becomes your account's internal ID. Unlike Apple, Google sends your name on every sign-in, not only the first. We don't ask Google for your email address, so we never receive it. You can change your name at any time in Settings, under Profile.

Accounts created with Apple and with Google are separate. Signing in with a different provider than you used before creates a new, empty account rather than opening your existing one; it does not merge them, and your original account is left untouched. If that happens to you, contact us and we can put it right.

In the iOS app, a push notification token for your device, so we can deliver the notifications described below. You can turn off notifications for the app entirely in your device's Settings at any time.

Content you or your teacher enter: if you're a teacher, the names and subjects of the students on your roster, their lesson schedule and attendance records, and payment records (how many lessons a payment covered and when it was made; never an amount, a card number, or any other financial detail, because Harmonic doesn't process payments). If you're a student, which teacher(s) you're linked to, and your own display name.

In-app messages: a record of the notifications sent to you (e.g. "a lesson was rescheduled," "your balance changed"), so you have a history of what happened and when.

If you contact us: the email address you provide, and whatever you write to us, so we can reply.

We do not collect your location, contacts, photos, or browsing activity, and the app does not use any advertising or analytics tracking software. The app has no third-party SDKs of any kind beyond the cloud services listed below. (The website's home page is different: see "This website".)

How we use this information

Solely to operate the app: showing you and the people you're connected to (your linked teacher or students) the schedule, attendance, payment, and messaging features described above. We do not use your information for advertising, and we do not sell or rent it to anyone.

Who we share it with

Amazon Web Services (AWS) hosts all of Harmonic's data and backend logic, purely as our infrastructure provider. It doesn't use your data for its own purposes. Apple handles Sign in with Apple and delivers push notifications to your device, as it does for any app using those services. Google handles Sign in with Google, if you choose it, and receives only what any sign-in requires: that you signed in to Harmonic. We don't share your information with anyone else.

The web app

You can also use Harmonic in a web browser, at harmonic.net.au. You sign in with Apple or Google as in the iOS app, and it's the same account with the same information, so everything in this policy applies to it in the same way.

To keep you signed in, your browser holds a sign-in token in its session storage, which it clears when you close the tab, and a sign-in lasts at most a day. The web app also remembers two settings in your browser's local storage: light or dark appearance, and how many notifications to show on a page. It sets no cookies, has no analytics, and talks only to Harmonic's own servers.

This website

The home page of harmonic.net.au uses Google Analytics to count visits: which site or search brought people there, the country and city they visited from, and the kind of device and browser they used. Google Analytics sets cookies so that a returning visitor isn't counted twice. It gets nothing from your Harmonic account, and nothing you enter in the app. Google handles this data under its own privacy policy, at policies.google.com/privacy.

Only the home page uses it. The help centre, this privacy page and the web app don't, and the iOS app has no analytics either. If your browser sends a Global Privacy Control or Do Not Track signal, the home page doesn't load Google Analytics at all, and you can also block it with Google's opt-out browser add-on or any content blocker.

Where your data is stored

All of Harmonic's data is hosted entirely within AWS's Australian region. Nothing is stored or processed in any other country: your information does not leave Australia.

Students' privacy

Harmonic can be used two ways: a parent or guardian may manage a pupil's account on their behalf, or a student old enough to manage their own account may sign in and use it directly. Either way, we collect only what's needed for the scheduling, attendance, payment, and messaging features described above, and nothing more, regardless of who holds the account or how old they are. If you're a parent or guardian and have any concern about a student's information, use the Contact Us button in Settings and we'll address it.

How long we keep your information, and deleting your account

Your information stays until you delete it. You can permanently delete your account at any time, without needing to contact anyone: in the iOS app from Settings → Delete Account, or in the web app from Delete Account in the account menu (on a phone, in Settings). Your account is the same in both, so deleting it in one deletes it everywhere.

Teachers: your entire roster (every student, lesson, and payment record you own) is permanently deleted, along with your messages. Linked student accounts lose access to that data.

Students: your own profile and messages are deleted, and you are unlinked from every teacher. Your teachers' rosters, and any other account linked to the same student (e.g. a second parent), are not affected.

If you signed in with Apple, deleting your account also revokes Harmonic's access to your Apple ID via Apple's own Sign in with Apple system.

Security

Your data is stored and transmitted using AWS's standard encryption in transit and at rest. Access to your account data is scoped so that only you (and, for a linked teacher/student relationship, the other party in that relationship) can read it.

Changes to this policy

If this policy changes, we'll update the date at the top of this page.

Questions about this policy or your data: send us a message with Contact us, at the bottom of every page on this website, or from Contact Us in the app's Settings. Either way, you'll be asked for your email address so we can reply to you.
