Privacy Policy

Last updated 27 August 2026

The short version. Your audio files are never uploaded for analysis — the engine runs in your browser and only the results reach us. We keep your email, your profile, your analysis results and whatever you post. We do not sell any of it, there are no advertising trackers, and you can have all of it back or deleted with one email.

1. Who is responsible

The data controller is the operator of Harmoniq DJ, an independent product run from Türkiye. Contact: hello@harmoniqdj.com. If you need the operator's registered details for a formal request — a data subject request, a regulator's enquiry, a legal notice — write to that address and they are provided.

This policy is written to meet Türkiye's KVKK (Law No. 6698) and the EU/UK GDPR. If you are in another country, the rights below are offered to you anyway.

2. What never leaves your device

This is the part most people ask about, so it goes first.

Your audio files are not uploaded for analysis. Key, BPM, energy and confidence are all computed by your own browser, on your own machine. No file is sent to a server, queued, or processed remotely. Unreleased promos stay where they are.

There is exactly one case where an audio file leaves your device, and you trigger it deliberately: attaching a track to a community post or a direct message. That file is uploaded so it can be delivered to the people you are sending it to. Nothing else uploads audio.

3. What we do store

DataWhyKept for
Email addressSigning in, password reset, service noticesUntil you delete the account
Username, display name, avatar, cover, bio, location, genres, SoundCloud linkYour public profileUntil you delete it or the account
PasswordSigning in — stored only as a salted hash by Supabase Auth, never in readable formUntil you delete the account
Analysis results: file name, key, BPM, energy, confidence, and a fingerprint of the fileYour library, and counting the free analysis cap. The fingerprint is what stops the same track being counted twice.Until you delete the track or the account
Folders, saved sets, set historyThe features themselvesUntil you delete them or the account
Posts, comments, likes, follows, blocksThe community feedUntil you delete them or the account
Direct messages and anything attached to themDelivering the messageUntil you or the other person deletes it, or the account goes
Usage events: which screens are opened, which features are used, a random session ID, referrer, and whether the device is phone/tablet/desktopKnowing which parts of the tool actually get used, and finding what is brokenRolling 12 months
Subscription status and renewal dateKnowing whether Pro is onUntil you delete the account
Payment event records from Polar — the subscription's status, dates and the email Polar holds for the purchaseTurning Pro on and off automatically, and having a record if a payment ever fails to reach your accountDeleted with the account, except what Polar must keep for tax

The file name is stored; the file is not. If your file names contain something you would rather we did not hold, rename before you analyse.

4. What we never do

5. Legal basis

PurposeBasis
Running your account and the features you usePerformance of the contract between us
Taking payment for ProPerformance of the contract
Usage events, keeping the service secure and workingLegitimate interest — kept minimal and never used to profile you
Service emails you cannot opt out of, such as a password resetPerformance of the contract
Anything genuinely optionalYour consent, which you can take back

6. Who processes data for us

ProviderWhat they handleWhere
SupabaseDatabase, sign-in, file storage for avatars and posted audioEU region
VercelServing the site; their access logs include IP addressesGlobal edge network
Polar Software, Inc.Payments as merchant of record — they receive your email and billing details; we never see your cardUnited States
Google Fonts, unpkg, jsDelivrFonts and icon files loaded by your browser; these hosts see your IP address as part of that requestGlobal
SoundCloudOnly when a page shows an embedded SoundCloud playerGlobal

Some of these are outside Türkiye and the EEA. Transfers rely on the providers' standard contractual clauses and, for KVKK purposes, on the conditions in Article 9.

7. Cookies and browser storage

Harmoniq sets no advertising cookies and no third-party tracking cookies, so there is no consent banner to click through.

What it does use is your browser's own storage, and only for things the app cannot work without:

8. Your rights

Under KVKK and the GDPR you can ask us to:

Write to hello@harmoniqdj.com from the address on your account. We answer within 30 days, and normally within a couple of days — it is one person reading that inbox, not a ticket queue.

If you are unhappy with how we handled it, you can complain to the Turkish Personal Data Protection Authority (KVKK Kurumu) or, in the EU/UK, your local data protection authority.

9. Deleting your account

Ask, and everything goes: profile, library, folders, sets, posts, comments, messages and usage events. It is not reversible, so export anything you want to keep first.

Two things survive, and only because the law requires it: records Polar must keep for tax and accounting on a purchase you actually made, and anything we are under a legal obligation to retain. Neither is used for anything else.

10. Security

Traffic is encrypted in transit. Passwords are stored as salted hashes and are never readable, by us or anyone else. Database access is restricted row by row, so one account cannot read another's data. Sign-in tokens expire and refresh. Changing your password signs out every other session.

No system is perfect. If there is a breach affecting your data, you will be told, and the authorities notified within the legal deadline.

11. Children

Harmoniq is not for under-16s. We do not knowingly collect their data; if we learn we have, the account is deleted.

12. Changes

Material changes move the date at the top and are emailed to registered users before they take effect.

13. Contact

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.
