Privacy

Updated August 19, 2026

This page describes what Dayglass Audio does with your data, in the order you are likely to meet it: first the analyzer, then a purchase, then advertising.

Who runs this service

The operator's legal name and business address go here before launch. For a privacy request, write to support@dayglassaudio.com.

What stays in your browser

Single-moment analysis runs on your device. When you select ANALYZE FOCUS, the audio is decoded and measured in the browser, and nothing about it leaves your machine.

What stem separation uploads

When you select AI SEPARATE SONG, more happens, because separation needs a GPU:

1. Your browser decodes the track to WAV and uploads it directly to a private storage bucket on Cloudflare R2. The upload link is signed for that one file and expires in ten minutes.
2. Modal, a GPU compute provider, reads that file, separates it into stems, writes the stems back to the same private bucket, and deletes your upload.
3. Your browser fetches the stems through Dayglass Audio, which checks that the request holds the one-time token issued for your separation.

Nobody else can reach those files. The storage bucket is private, the stems are not public, and the token that authorizes them is held in your browser's memory for that session alone.

How long it is kept

Your upload is deleted as soon as the stems exist. The stems are deleted 90 minutes after the last time you fetched one, when you cancel the job, or when you load a different file, whichever comes first. A storage rule deletes anything still present after one day as a backstop, in case the usual cleanup fails.

Upload only audio you have permission to process.

Limiting abuse

Separation costs real GPU time, so it is rate-limited. Before an upload, Cloudflare Turnstile checks that you are a person; that check happens only when you request a separation, and the script that runs it is not loaded before then. To count separations per day, Dayglass Audio stores a one-way hash of your Internet Protocol (IP) address combined with the date and a rotating secret. Your address itself is never stored, and yesterday's hash cannot be matched to today's.

Purchases

Checkout runs on Stripe. With Stripe Managed Payments, Stripe is the merchant of record: it takes the payment, calculates the tax, and sends your receipt. Your card details go to Stripe and never touch Dayglass Audio.

After a payment settles, Stripe notifies Dayglass Audio, which records your email address, the Stripe references for the order, the amount, the currency, and the payment and delivery status. That record exists so support can find your purchase, reissue a download link, and handle a refund or a dispute, and so the operator can meet its tax and accounting obligations. It is kept for as long as those obligations require.

Your download link is emailed through Resend, which processes your email address and the contents of that one message in order to deliver it.

Advertising

The analyzer is free, and ads are one way it pays for itself. No ad script loads until two things are true: the account has a Google-certified consent platform configured, and you have selected ALLOW ADS. Until both hold, no request goes to Google at all.

When ads are on, Dayglass Audio requests non-personalized ads. Google can still use the page context, your approximate location, fraud-prevention signals, and limited browser storage to deliver and measure them. Ads appear only inside the free analyzer. There are none on checkout, on the download page, or on this page.

To change your choice at any time, select Ad choices in the footer. The analyzer works the same either way.

Browser storage

Dayglass Trace stores your advertising choice, your interface preferences, and your mini-game high score in your browser's local storage. During a download, a short-lived cookie holds your download authorization for ten minutes. To remove the stored values, clear this site's browser data.

Service logs

Cloudflare records standard request information: your IP address, browser type, the path you requested, the response status, and the time. These logs exist for security and reliability. Authorization headers, upload links, download tokens, and payment signatures are kept out of them.

Processors

Dayglass Audio uses these services, each for one job:

• Cloudflare — hosting, the Turnstile check, the database, and the private storage your audio passes through.
• Modal — the GPU that separates your track. Its access is limited to the audio bucket.
• Stripe — checkout, payment, tax, and receipts, as merchant of record.
• Resend — the delivery email.
• Google AdSense — advertising, and only once you allow it.

Your choices

To keep your audio off the network entirely, use single-moment analysis instead of stem separation. To use the analyzer without ads, select CONTINUE WITHOUT ADS. To have your order record removed, write to support; what can be deleted depends on how long tax and accounting rules require it to be kept.

The data rights that apply to you, and the governing law, go here before launch, once the operator's jurisdiction is confirmed.
