TrackSensei ("we", "us", "our") operates the website tracksensei.com and the TrackSensei web application. This Privacy Policy explains how we collect, use, and protect your information when you use our service.
Account information: When you register, we collect your email address and a display name (optional). Your password is stored as a one-way cryptographic hash — we never store or see your actual password.
Uploaded files: When you use TrackSensei to analyze a track, you upload audio files (WAV, MP3, FLAC, AIFF, OGG) and/or Ableton Live project files (.als). These files are processed by our analysis engine and stored temporarily on our servers for the duration of the analysis.
Chat conversations: Messages you exchange with the AI feedback assistant are stored so you can revisit your conversation history.
Usage data: We track how many analyses and chat messages you use each month to enforce tier limits. We also collect standard server logs (IP address, browser type, timestamps) for security and debugging purposes.
Payment information: Payments are processed by Stripe. We do not store your credit card number or bank details on our servers. Stripe handles all payment data under their own Privacy Policy.
We use your information to provide and improve TrackSensei, specifically to: process your audio analyses, deliver AI-powered production feedback, manage your account and subscription, enforce usage limits per tier, send essential service emails (account verification, password resets), and detect and prevent abuse or fraud.
Your uploaded audio data and project files are processed by our analysis engine on our servers. Analysis results (not your raw audio) are sent to Anthropic's Claude API to generate production feedback. Anthropic processes this data under their Privacy Policy and does not use your data to train their models when accessed via their API.
We do not sell, rent, or share your personal data with third parties for marketing purposes. We share data only with:
Uploaded audio and project files are deleted immediately after your analysis completes successfully. In case of a failed analysis, files are retained for up to 24 hours to allow a retry and then automatically deleted. Analysis results (reports, scores, chat messages) are retained for 30 days, after which they are permanently deleted. Your account data is retained as long as your account is active. If you delete your account, all associated data is permanently removed within 30 days.
We take security seriously. Measures include: bcrypt password hashing, JWT-based authentication, rate limiting and brute-force protection, encrypted connections (HTTPS/TLS), input validation and sanitization on all endpoints, and regular security reviews.
If you are located in the EU, you have rights under the General Data Protection Regulation (GDPR). You have the right to: access the personal data we hold about you, request correction of inaccurate data, request deletion of your account and data (the "right to be forgotten"), data portability (receive your data in a portable format), object to processing of your data, and withdraw consent at any time.
To exercise these rights, email us at hello@tracksensei.com.
We use essential cookies only — specifically a JWT authentication token stored in your browser. We do not use tracking cookies, analytics cookies, or advertising cookies.
TrackSensei is not intended for users under 16 years of age. We do not knowingly collect data from minors.
We may update this Privacy Policy from time to time. We will notify registered users of significant changes via email. Continued use of the service after changes constitutes acceptance of the updated policy.
