Terms of Service

Last updated 27 August 2026

The short version. Harmoniq analyses your music in your own browser and keeps the results in your account. Free covers the whole toolkit and your first 200 analyses; Pro removes that cap for $3 a month or $20 a year. You can cancel whenever you like and your library stays yours. Don't upload other people's tracks as your own, and don't attack the service. That is the whole deal — the sections below just say it precisely.

1. Who you are agreeing with

Harmoniq DJ ("Harmoniq", "we") is an independent product, built and run from Türkiye by a working DJ. It is not a company with a support department — it is one person, and you reach that person directly at hello@harmoniqdj.com. Using the service at harmoniqdj.com means you accept these terms. If you don't, don't use it.

Payments are handled separately by Polar Software, Inc., who act as the seller of record for every purchase. Their buyer terms cover the payment itself; these terms cover the service. See section 6.

2. What the service does

Harmoniq detects musical key, BPM and energy in audio files, scores its own confidence in each result, and gives you tools built on those results — a Camelot wheel, a compatibility matrix, a set builder, folders, saved sets, export to DJ software, and a community feed.

Analysis runs on your device. Your audio files are read by your own browser and are not uploaded to any server for analysis. What syncs to your account is the result: key, BPM, energy, confidence, and the file name.

There is one exception, and it is one you choose: if you attach a track to a community post or a direct message, that file is uploaded so it can be delivered. Nothing else uploads audio.

3. Your account

4. What you can and cannot do

Analyse whatever you legally have. Promos, unreleased edits, bootlegs you made, a friend's WAV — none of that is our business, and none of it reaches our servers.

What is not allowed:

We can remove content that breaks these rules and, for repeated or serious cases, close the account. Where it is reasonable to do so, you will hear from us before that happens.

5. Your content stays yours

Your music, your analysis results, your sets and your posts belong to you. We claim no ownership of them.

To run the service we need a limited licence to store and display what you post: showing your set on the feed, your avatar on your profile, your track in a message thread. That licence covers operating Harmoniq and nothing else — we do not sell your content, license it on, or train models on your audio. It ends when you delete the content or your account.

6. Pro, billing and cancellation

Free gives you the full toolkit and 200 track analyses. Pro removes the cap on analysis and changes nothing else. Prices are $3 per month or $20 per year, in US dollars.

Polar Software, Inc. is the merchant of record. They are the legal seller for your purchase: they take the payment, charge and remit any applicable tax, issue the invoice, and handle refunds and card disputes. Their buyer terms apply to the transaction.

Subscriptions renew automatically until you cancel. You can cancel at any time from the billing portal — the "Manage subscription" button on the Plans screen inside the app takes you there. Cancelling stops the next charge; you keep Pro until the end of the period you have already paid for, then drop back to Free. Nothing in your library is deleted when that happens.

Refunds are covered on our Refunds and Cancellation page.

If we ever change the price, existing subscribers are told by email before it affects them, and it never applies to a period already paid for.

7. Availability, and the honest part about accuracy

Harmoniq is run by one person. It will occasionally be down, and features will change. We do not promise uninterrupted service.

Key detection is a judgement, not a measurement. That is exactly why every result carries a confidence score: a low score means the engine is telling you it is unsure, and you should trust your ears over the number. Harmoniq is a tool for your decisions, not a replacement for them. We are not responsible for how a set goes.

The service is provided "as is". To the extent the law allows, we exclude implied warranties, and our total liability to you for any claim is capped at what you paid us in the twelve months before it arose. Nothing here limits liability that cannot legally be limited — including for fraud, or death or personal injury caused by negligence.

8. Ending it

You can delete your account whenever you want; write to hello@harmoniqdj.com and it is done. Deletion removes your profile, library, folders, sets, posts and messages. It cannot be undone, so export anything you want to keep first.

We can suspend or close an account that breaks section 4, or if we are legally required to. If we close a paid account for a reason that is not your fault, we refund the unused part of the period.

If Harmoniq ever shuts down, you get at least 30 days' notice by email and a way to export your data, and any prepaid time is refunded.

9. Changes to these terms

When these terms change materially, the date at the top changes and registered users are told by email at least 14 days before it takes effect. Carrying on using the service after that means you accept the new version. If you don't, cancel — and if you were mid-period on Pro, we refund the rest of it.

10. Law and disputes

These terms are governed by Turkish law, and the courts and consumer arbitration committees of Türkiye have jurisdiction. If you are a consumer elsewhere, this does not take away the protections of the mandatory consumer law where you live.

Before anything formal: write to us. Almost everything is fixable by email, usually the same day.

11. Contact

hello@harmoniqdj.com

Billing questions can also go to Polar, the merchant of record, at support@polar.sh. Anything about the service itself — your account, the engine, a bug — comes to us.

If the Turkish and English versions of this text conflict, the Turkish version prevails. This does not remove the protections of the mandatory consumer law where you live.
