Privacy Policy
What Stem Splitter AI collects, how your songs are processed, and when they are deleted
Introduction
This Privacy Policy explains what Stem Splitter AI ("we", "us") collects when you use stemsplitterai.top, how we use it, and how long we keep it. Stem Splitter AI is an online stem splitter: you upload a song, and we separate it into vocals, drums, bass, guitar, piano, and other stems.
Information We Collect
- Account information: your email address and name when you sign up, or the profile Google shares when you sign in with Google.
- Files you upload: the songs and videos you send to the stem splitter, and the stems we produce from them.
- Usage information: which features you use, how many minutes of audio you process, and basic technical data such as your IP address, browser, and device, used to run the service and prevent abuse.
- Payment information: when you buy minutes or a plan, our payment provider processes your card. We receive the purchase record, not your card number.
Songs You Upload
- Purpose: an uploaded file is used only to produce the stems you asked for. We do not listen to it, publish it, or use it to train models.
- Storage: uploads, previews, and finished stems are stored in Cloudflare R2 and deleted automatically 24 hours after upload.
- Processing: separation runs on cloud GPUs operated by Modal. The worker reads your file through a short-lived private link and writes the stems back the same way; it does not keep copies.
- In your browser: the browser may keep your file and editing preferences locally so a page reload does not lose your work. You can clear this with your browser's site data settings.
How We Use Information
- To run the stem splitter and deliver your stems
- To keep track of your free preview, free minute, and purchased minutes
- To send account emails, such as verification and password reset
- To answer your messages to support
- To detect and stop abuse, such as automated uploads
We do not sell your personal information.
Third-Party Services
We rely on these providers to run the service: Cloudflare (hosting, database, file storage, and email), Modal (GPU processing), Google (optional sign-in), and our payment provider (checkout and billing). If analytics is enabled, it measures page visits in aggregate. Each provider handles data under its own privacy policy.
Data Retention
Uploaded files and stems are deleted after 24 hours. Account and purchase records are kept while your account exists. You can delete your account at any time in Settings, which removes your profile and job history.
Your Rights
You can access, correct, or delete your account information in Settings, or ask us to do it for you through the contact page.
Data Security
Files are transferred over HTTPS and stored privately; download links expire. No method of transmission or storage is completely secure, but we limit access to what the service needs.
Changes to This Privacy Policy
We may update this policy as the service changes. The date at the top shows the latest version.
