Acceptable Use Policy

Last updated: June 12, 2026

This Acceptable Use Policy describes what you can and cannot do with the Service. It's part of our Terms of Service. Violations can result in content removal, account suspension, or termination.

The point of this policy: to keep the Service useful, legal, and safe for everyone. It is not exhaustive — we use reasonable judgment for cases not covered here.

1. You're responsible for what you upload

You may upload audio that:

✅ You created yourself (your own recording, performance, or composition)
✅ You purchased or licensed and are processing for personal, non-public use
✅ Is in the public domain
✅ You have explicit written permission from the rights holder to process

You may not upload audio that:

❌ You don't have rights to (this includes most commercially-released music — even music you "own" on Spotify or Apple Music is licensed for streaming, not for processing)
❌ Was obtained through ripping a streaming service
❌ Contains personal data of others without their consent (private recordings, voicemails, etc.)
❌ Is illegal in your jurisdiction or in the United States or Brazil

If you're not sure whether you have rights to a piece of audio, the safest answer is: don't upload it.

2. The processed output is yours, but it's still derivative

When you process audio through our Service, the result is a derivative work of the original. Your rights to the output match (or are narrower than) your rights to the input.

If you uploaded audio you don't have rights to:

The output is also subject to the original copyright
You can't release it publicly, sell it, or distribute it commercially
We are not responsible for what you do with it after download

If you uploaded audio you own or have licensed:

The output is yours to use within the scope of your license

3. Prohibited uses

You may not use the Service to:

3.1 Process copyrighted material without rights

This is the big one. The Service is built so that processing is fast, but processing alone doesn't make it legal. Don't use us to make derivatives of someone else's recordings unless you have permission.

3.2 Bypass content protection

Don't upload material you obtained by circumventing DRM, ripping a streaming service, or otherwise breaking digital protection.

3.3 Distribute or resell the output as a commercial product

You may not take a stem separation or pitch-shifted version of a copyrighted song and:

Upload it to streaming platforms
Sell it on Bandcamp, Beatport, or anywhere else
Use it in a commercial podcast, YouTube monetized video, ad, or film without the appropriate licenses
Claim authorship of someone else's recording

3.4 Harass, abuse, or threaten others

No uploading audio designed to harass, defame, or impersonate someone
No using shared library features (when available) to send abusive content

3.5 Compromise the Service

No reverse-engineering, decompiling, or scraping
No attempting to bypass authentication, billing, or rate limits
No automated abuse of free tools (we rate-limit; don't try to circumvent)
No DDoS, exploitation, or vulnerability probing without coordinated disclosure
No uploading malware, viruses, or executable payloads disguised as audio

3.6 Violate any law

Using the Service to do anything illegal in your jurisdiction is prohibited. This includes but isn't limited to copyright infringement, defamation, hate speech, child exploitation, fraud, identity theft, and unauthorized data collection.

3.7 Resell the Service

You may not white-label or resell the Service to your own customers without a written reseller agreement.

4. Use of free tools (no account)

The free tools (vocal remover, key changer, song slowdown) are subject to the same content rules as the main Service.

Additional rules for free tools:

One file per request. No batching scripts.
Reasonable rate of use. Hammering the endpoint to process hundreds of files counts as abuse.
No commercial pipelines. Don't build a downstream commercial product whose backend is our free tool.

We rate-limit by IP and may block abusive sources.

5. Reporting violations

If you see content or behavior that violates this policy, email guilhermebilton@gmail.com with the subject line “Abuse report” and:

A description of what you're reporting
The URL or username (if available)
Why you think it violates the policy
Your contact information (so we can follow up if needed)

6. Enforcement

We respond to violations on a case-by-case basis. Our response may include:

A warning email
Removing the offending content
Suspending features (e.g., disabling free-tool access from your account)
Suspending your account temporarily
Terminating your account permanently
Reporting to law enforcement (for clearly illegal activity)
Banning future signups from your IP/email

For repeated copyright infringement, we terminate accounts under our DMCA repeat-infringer policy. We may also report repeat infringers to rights-holders' enforcement organizations.

7. Appeals

If you believe enforcement against you was a mistake:

Email guilhermebilton@gmail.com with the subject line “Appeal” within 30 days
Include your account email and a description of why the action was wrong
We respond within 14 days

For DMCA-related removals, the formal counter-notice process is described in our Terms of Service section 11.

8. Updates to this policy

We may update this AUP. Material changes will be announced via email at least 14 days before they take effect.

9. Common questions

"I bought the song on iTunes / Bandcamp. Can I process it?"

For personal, non-public use (practice, karaoke at home), most jurisdictions consider this fair use. For anything beyond that — releasing the result, distributing, using commercially — you'd need additional rights from the publisher and the recording's owner. When in doubt, treat it as a personal-use derivative and don't share or distribute.

"I'm in a cover band. Can I use this for our gigs?"

You can use the processed track for your own performance preparation. Performing covers in a venue typically requires the venue to have a public-performance license (ASCAP/BMI in the US, ECAD in Brazil) — that's their responsibility, not yours. Selling a recording of a cover requires additional licenses.

"Can I upload my band's own recordings?"

Yes. If your band owns the recording, you can do anything you want with it.

"I have a Spotify download. Can I process that?"

No. Spotify downloads are encrypted and the license terms specifically forbid processing or extraction. Same for Apple Music, YouTube Music, etc.

"Can I use the result in my YouTube video?"

If the original is copyrighted and you don't have a sync license, no — YouTube's Content ID will likely flag it. If the original is yours, public domain, or you have a sync license, you're fine.

"What if I'm a teacher using this for educational purposes?"

Educational use can fall under fair use in many jurisdictions, but it's not universal. Use within a private classroom (not redistributed) is generally safer than uploading to a public platform.
