Privacy Policy

This policy explains what personal data we process when you use Seimix ("we", "the service"), why and for how long, your rights, and how to reach us. It is prepared under Turkey’s KVKK and, where applicable, the GDPR.

• Account info: the email you sign in with (email link, Google or Apple sign-in).
• Audio you upload: the stem/track files you upload for mixing/mastering and the resulting mixes.
• Technical data: IP address, browser info and request logs, for security and debugging.
• Payment data: your subscription status. Card details are never stored on our systems — payments run through LemonSqueezy.

No. Files you upload are used only to perform the mix/mastering you asked for. Without your explicit consent they are never used for AI model training or shared with third parties.

• Audio files and mixes: kept for a limited time after processing and deleted automatically on a regular basis. You can request earlier deletion anytime.
• Account info: while your account is active; removed when you delete your account.

With the infrastructure providers needed to run the service: authentication and database (Google Firebase), hosting and network (Cloudflare), payments (LemonSqueezy). They process your data only to provide the service. We never sell your data.

In addition, measurement tools run only if you accept them in the cookie banner: Google Analytics (to understand how the pages are used) and Google Ads (to measure whether an ad led to a subscription). They store cookies in your browser and share limited data with Google: the pages you view, approximate location, device and browser information, the ad click identifier, and — when you start a subscription — the transaction id, amount and currency. Your audio files, your mixes and the mix instructions you type are never sent to them. If you do not accept, these tools are never loaded. You can change your choice at any time with the “Cookie settings” link at the bottom of the page.

You have the right to:

• Learn what data of yours is processed,
• Request correction or deletion,
• Request deletion of the files you uploaded,
• Close your account entirely,
• Object to processing.

For these requests contact us at support@seimix.com.

To delete your account or uploaded files, just email support@seimix.com. We’ll handle your request as soon as possible.

Your data is encrypted in transit and at rest. API access is protected by authentication; your audio files are not reachable via a public link. That said, no transmission over the internet is 100% secure.
