Privacy Policy

Operator and Contact

The service is operated via samplab.pro. We are committed to handling your audio and personal data transparently, prioritizing local processing directly on your device whenever possible. If you have questions regarding your privacy, contact support@samplab.pro.

Browser-Local Tools and Audio Privacy

Our browser tools run entirely on your device: audio to MIDI, tempo and key, chords, frequency-band splitting, MIDI to audio, lead sheet, audio cutter, WAV to MIDI, and the MIDI editor. Frequency-band splitting isolates frequency ranges and is not vocal, drum, or bass separation. Audio used in these tools stays in your browser and is never uploaded to our servers. Browser tools do not use credits, and an account is optional. A cross-page action can keep the current audio in this browser for the next tool in the same tab for up to 15 minutes.

Local 6-track stem separation also runs in your browser and does not upload audio. The first time you use local 6-track stem separation, your browser downloads model files from the site into your browser cache.

Cloud Processing and Third Parties

Using AI lyrics, AI music, or Cloud Standard stem separation requires an account. Starting one of these tasks uploads the specific input required to produce the result. Cloud Standard stem separation converts your audio into an MP3 in your browser, uploads it, and passes it to WaveSpeed, a third-party AI platform, which returns the separated tracks. AI lyrics and AI music tasks send the text prompt and lyrics you entered to WaveSpeed. Audio and text are sent solely to create the requested output, and WaveSpeed handles that data under its own terms and privacy policy. Results remain private to your account.

Payments are processed in US dollars through Waffo. We do not collect or store full payment card numbers. Transactional emails are sent via Resend, and website hosting and security are provided by Cloudflare. We do not display ads and do not sell personal information. We may share information with law enforcement or regulatory authorities only when strictly required by applicable law.

Account Data and Cookies

Creating an account stores your name, email address, authentication records, and session information. These records may include your IP address, browser information, and preferred interface language. Registering an account alone does not upload any files. You may register and sign in exclusively through your Google account.

We use session cookies to keep you signed in, remember your preferences across eleven interface languages, and protect account security. Cookies may also be used to evaluate website usage. Our usage measurement does not receive audio, MIDI contents, file names, raw error text, or account identifiers. We respect browser Do Not Track signals.

Data Retention and Library Storage

Uploaded audio files and separated tracks for a cloud task stay private for 7 days after they are created, and are then deleted automatically. The underlying task record (file name, duration, credits charged, and status) is kept until your account is deleted.

Saving a result to your private library is a separate action. Audio tools accept files up to 50 MB, ranging from 1 second to 10 minutes in duration. The private library accepts WAV and MIDI files up to 50 MB, UTF-8 lyrics text up to 64 KB, and up to 100 saved files per account. New files saved on an account without a paid membership are kept for 180 days. An active paid membership preserves saved files through the end of the paid period plus 3 calendar months. Ending a membership does not shorten retention already granted. Files are deleted automatically after their displayed expiration date; the library is not a permanent backup.

You can delete individual saved files or delete your account and its saved works in account settings. A failed account deletion stays pending until it can be retried. Deleting the account permanently removes saved works, private task files, and task records. For purchases and billing terms, review our Refund Policy.

Sheet Music Edit Assistant

The optional edit assistant in Audio to Sheet Music sends the instruction you type and the score data (notes, bars, key and tempo) to WaveSpeed, a third-party AI platform, to work out the change. It never sends audio. We store only a count of requests per account and day and the cost against a monthly allowance, not the instruction, the score or the reply. WaveSpeed handles what it receives under its own terms and privacy policy. WaveSpeed has told us that it keeps the content of these requests for up to 7 days and does not use it to train models.
