§ 1 Scope

These Terms of Service govern the use of the website and services of track-finder.com, operated by Traffic netWorks, Speditionstraße 8, 40221 Düsseldorf, Germany (hereinafter "Provider"). By using the website, you agree to these Terms.

§ 2 Description of Service

track-finder.com is a harmonic-mixing database and DJ tool for electronic music. The service offers, in the current version, the following features:

• A searchable database of track metadata (title, artist, label, Camelot key, BPM, energy, genre).
• Personal accounts for saving favorites, building playlists, and recording listening history.
• An audio-slicing tool that analyzes a user-supplied audio file and cuts it into beat-perfect 8-bar loops with detected key + BPM metadata, plus optional stem extraction (vocals / drums / bass / synth) via the Demucs model.
• A web-based loop player and DJ mixer for layering and previewing those loops.
• Optional public sharing of recorded DJ mixes with comments by other users.

Some features (including audio slicing, mix recording, and mix sharing) require a user account. Core track browsing is available without registration.

§ 3 Usage Requirements

• Use of the service is permitted for users aged 16 and over. Users under 18 must have parental consent.
• You need a modern web browser with an internet connection. iOS Safari and Chromium-based browsers are best supported.
• Some features require a user account, which can be created with an email address and password or via "Sign in with Google" (see § 11).
• You are responsible for keeping your account credentials secure and for any activity that occurs under your account.

§ 4 User Content & Audio Uploads

The slicing and DJ tools let you upload audio files (MP3, FLAC, WAV and similar) from your own device for personal use. These rules apply to anything you upload:

• Rights. You may only upload audio for which you hold the necessary rights — that is, music you created yourself, public-domain material, properly licensed material, or content you are otherwise legally entitled to process. You bear sole responsibility for any infringement of third-party copyright, neighbouring rights, or other rights arising from your uploads.
• Limited license to the Provider. You grant the Provider a non-exclusive, worldwide, royalty-free, time-limited license to store, decode, analyze, transcode, slice and stream your uploaded audio strictly for the purpose of providing the service to you. This license ends when you delete the file or your account.
• No public distribution by default. Uploaded source audio is private to your account. Loops and stems derived from your uploads remain private unless you explicitly publish a mix that uses them via the public mix feature.
• Storage. Your uploads and derived files are stored on Cloudflare R2 infrastructure in user-namespaced paths. The Provider may delete files older than 90 days that are no longer referenced by any active job, mix, or playlist.
• Prohibited content. Audio containing illegal content, hate speech, threats, sexual content involving minors, or material that violates the rights of third parties is strictly prohibited. The Provider reserves the right to remove such content without notice and to suspend the responsible account.

§ 5 Public Mixes & Comments

If you publish a mix to the public mix section, you grant other users the right to listen to and comment on the mix within the service. You may delete a published mix at any time, which removes public visibility going forward.

Comments are moderated automatically (rule-based and AI-assisted) and may be removed by the Provider without prior notice if they violate these Terms — in particular, comments containing hate speech, slurs, harassment, threats, sexual content, doxxing, advertising/spam, or content unrelated to the mix in a clearly disruptive way. Repeated violations may lead to account suspension.

§ 6 Acceptable Use

You agree not to:

• Upload, share, or publish content that infringes third-party rights or applicable law.
• Use the service to redistribute commercial music tracks you have no rights to.
• Use automated means (scrapers, bots, headless browsers) to mass-harvest track metadata or evade access controls.
• Reverse-engineer, decompile, or otherwise extract the source code of the service except as permitted by mandatory law.
• Use the service to deliver malware, conduct denial-of-service attacks, or otherwise interfere with availability for other users.

§ 7 Availability

The Provider strives for high availability of the website and its dependent services (database, slicer, R2 storage, third-party login). The Provider makes no guarantee of uninterrupted availability. Maintenance work, technical faults, dependency outages (Supabase, Cloudflare R2, Apify, Demucs hosting, Google Sign-In) or force majeure may cause temporary interruptions. There is no entitlement to availability or to retention of free-tier feature levels.

§ 8 Intellectual Property

All content on track-finder.com created by the Provider (the website, design, code, brand assets, the harmonic-mixing UI, documentation, the curated parts of the track-metadata database) is the property of Traffic netWorks and is protected by copyright. Reproduction, distribution, public display, or systematic data extraction without express written permission is prohibited.

Track metadata (artist, title, BPM, key, etc.) is provided for personal, non-commercial reference within the service. Some metadata is sourced from third-party providers; their rights apply in addition to ours.

Audio files you upload remain your property. The license you grant the Provider under § 4 is solely for service delivery.

§ 9 Limitation of Liability

The Provider is not liable for:

• Damages arising from improper use of the service or of files you upload.
• Data loss due to technical faults, dependency outages, or account deletion.
• Damages caused by third parties, third-party services (Supabase, Cloudflare, Apify, Google, payment providers), or content linked from external sources.
• Indirect damages, loss of profit, or consequential damages.
• Inaccuracies in detected BPM / key / beat-grid output — these are generated by audio-analysis models (madmom, Demucs) and are inherently approximate. The Provider exposes a manual override so you can correct any detection mistake; relying on auto-detected metadata for time-critical performance is at your own risk.
• Any consequences of using the service in a live-performance context, including but not limited to audio glitches, sync drift, or unexpected playback behavior.

Liability for damages resulting from injury to life, body, or health, as well as for intent and gross negligence, remains unaffected.

§ 10 Account Termination & Deletion

You may delete your account at any time via the account-settings page or by writing to support@track-finder.com. Account deletion removes your profile data, playlists, mix recordings, comments, and the personal audio files you have uploaded. Public comments you authored under a deleted account are anonymized rather than removed, so that the conversation context for other users remains intact.

The Provider may suspend or terminate accounts that materially violate these Terms (in particular § 4 prohibited content or § 6 acceptable use), with notice where feasible. In urgent cases (active abuse, legal threat, service-wide impact) suspension may be immediate.

§ 11 Third-Party Login (Google Sign-In)

track-finder.com offers the option to register and log in using "Sign in with Google", provided by Google Ireland Limited (Gordon House, Barrow Street, Dublin 4, Ireland; for users outside the EEA: Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA).

Additional third-party terms: when using Google Sign-In, the Google Terms of Service and Google Privacy Policy additionally apply. These are concluded directly between you and Google; the Provider is not a party to them and has no influence over them.

Responsibility for your Google account: you are solely responsible for managing your Google account securely (strong password, two-factor authentication, recovery options). Loss, suspension, or compromise of your Google account may also affect access to your track-finder.com account.

Availability: the Provider has no control over the availability or functionality of Google Sign-In. If Google discontinues, modifies, or temporarily interrupts the service, login via Google may not be possible at times. You can fall back to email/password login or contact the Provider at support@track-finder.com.

Account linking and unlinking: when you first sign in with Google, the Provider links your Google account ID ("sub" claim) to your track-finder.com account. You can revoke third-party access at myaccount.google.com/permissions. After unlinking, you can continue to sign in with your email address and a password you set.

Data collected: which data is transmitted from Google to the Provider (Google account ID, email address, first/last name, profile picture URL, email verification status) is described in the Privacy Policy.

Limited Use: the Provider uses information received from Google APIs exclusively to provide the track-finder.com login and personal-account features, in compliance with the Google API Services User Data Policy (Limited Use). No data received via Google APIs is shared with third parties for advertising purposes.

No liability for third-party services: the Provider is not liable for damages caused by outages, security incidents, data loss, or changes by Google, to the extent permitted by law. The limitations of liability in § 9 apply accordingly.

Termination of third-party feature: the Provider reserves the right to discontinue Google Sign-In at any time without separate notice, or to replace it with other third-party login services. Existing accounts remain accessible via email/password.

§ 12 Amendments to Terms

The Provider reserves the right to amend these Terms at any time. Amended Terms will be published on the website. Material changes will be announced via in-app notification or to the email address associated with your account at least 14 days before they take effect. Continued use after an amendment constitutes acceptance of the amended Terms.

§ 13 Governing Law

The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods. Mandatory consumer-protection provisions of the user's country of residence remain unaffected for consumers within the EU.
