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
Dayglass Audio is operated by Simon Nardia, a sole proprietor based in Oklahoma, United States.
Purchases are sold by Stripe as merchant of record. For anything at all, including a postal address if you need one for a formal notice, write to support@dayglassaudio.com.
For a privacy request, write to support@dayglassaudio.com.
What stays in your browser
Loading a file decodes and measures it in your browser, and nothing about that leaves your machine. The same is true of RECORD INPUT, and of stems you separated yourself and loaded with MY OWN STEMS.
What stem separation uploads
When you select AI SEPARATE SONG, more happens, because separation needs a GPU:
- 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.
- 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.
- 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, separate it on your own machine and load the stems. 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.
Your rights over this data
Whatever country you are in, you can ask what is held about you, ask for it to be corrected, and ask for it to be deleted. Write to support@dayglassaudio.com and you will get an answer within 30 days.
Some of it cannot be deleted on request. An order record is needed to meet tax and accounting obligations, and those set how long it is kept rather than this policy. Everything else, including your account and its history, can be removed.
If you are in the United Kingdom or the European Economic Area, the UK GDPR and the GDPR give you further rights, including access, correction, erasure, restriction, objection, and data portability, and a right to complain to your national supervisory authority. Dayglass Audio relies on performing your contract for order data, on legitimate interests for security and abuse prevention, and on your consent for advertising.
If you are in California, you can ask what categories of personal information are collected and request deletion. Dayglass Audio does not sell or share personal information as those terms are defined by the CCPA.
