# Privacy Policy > How Mix Chops handles your information: what we collect, why, where it is stored and your rights. Page: https://mixchops.com/privacy Last updated 4 November 2026 Mix Chops is an ear-training site at mixchops.com, run by Dan Murtagh (ABN 48 815 594 360), a mix engineer and audio educator in Melbourne, Australia. This policy explains what information Mix Chops handles, why, where it is kept and what you can do about it. We handle personal information under the Australian Privacy Act 1988 and the Australian Privacy Principles, and we aim to meet the GDPR for visitors in the European Economic Area and the UK. ## The short version - You can use every exercise without an account. Your progress is then saved only in your own browser. - An account is optional. If you create one, we keep your email address (and, with Google sign-in, your name and profile picture) and your training progress, so it follows you between devices. - With an account, Dan emails you ear training tips, new exercises and Mix Chops news. Every email has an unsubscribe link, and unsubscribing doesn’t touch your account. - If you give us a first name, we keep it to greet you on the home page and, if you add it on the ear test result, to put on your result card: in your browser, and on your account if you’re signed in. It’s optional, and you can change or clear it on your profile page or the ear test result. - We use Google Analytics to understand how the site is used. We don’t send it your email address or name. - When something on the site breaks, your browser sends us a short technical error report. It never includes your email address, name or account details. - If you’re signed in, Ask Dan, the AI mentor in the EQ, compression, balance and space exercises, writes replies to what you tap or type. The exercise details go to Anthropic, which runs the AI, without your name or email address. - If you subscribe to Mix Chops Pro, Stripe takes the payment. We never see your card number; we keep your plan and its dates, so Pro works on your account. - With Pro you can upload your own songs. StemConsole, another service run by Dan, splits them into parts and keeps the parts for about 90 days. - We don’t sell your information, show ads or share your data with advertisers. - You can delete your account yourself at any time from your profile page. ## 1. Information we collect ### Progress saved in your browser When you train, Mix Chops saves your progress in your browser’s local storage: level scores, XP, rank, streaks, badges, daily-session history, your accuracy on each frequency band, your recent misses in Identify (for its practice rounds), your answers in the compression and balance exercises, your last twenty answers at each level of Identify (with the band played and the one you picked), the compression drills and the balance exercises (for your plan for today on the Daily page), and your ear test results. If you’re signed in, it also keeps a monthly snapshot of your accuracy on each band (your ear print). It stays on your device and isn’t sent to us unless you sign in. Clearing your browser’s site data removes it. ### Your first name (optional) Mix Chops may ask what to call you, so the home page can say “Welcome back” with your name, and the ear test result lets you add it to your result card, so the image you share reads, for example, “Sam got 2/3 on the Mix Chops ear test”. It’s optional and only for the greeting and that card; the card is made in your browser and only goes where you share it. If you give a first name, it’s saved in your browser’s local storage, and if you’re signed in, on your account too so it follows you to other devices. With Google sign-in we use the first name Google shares (see below) unless you change it. If you gave a first name in that browser in the hour before you signed in (on the ear test result card, say) and your account doesn’t have one yet, that name is used instead and saved to your account. It isn’t sent to Google Analytics or error reports, Ask Dan doesn’t use it, and it’s never sent to Anthropic. To change or remove it, use the First name field on your [profile page](https://mixchops.com/me#account), or the name field on the [ear test](https://mixchops.com/ear-test) result (empty it, or press Clear), which works signed out too: clearing it removes the name you gave from your browser and your account and stops the greeting. With Google sign-in, the name Google shared stays with your account details until you delete the account. Signing out removes it from that browser, and deleting your account removes it from our servers. ### Your account (optional) If you sign in, we collect: - **Email sign-in:** your email address, and your first name if you choose to give one. - **Google sign-in:** the details Google shares with us, which are your name, email address, profile picture and a Google account identifier. We never see your Google password. - **Your training progress:** the same progress described above, saved to your account so it syncs across devices. - **Sign-in records:** our account provider keeps basic security logs, such as when you signed in and the IP address and browser used. - **The Pro list (only if you join):** a note on your account that you joined and when, so we can email you when Mix Chops Pro opens. Ask us to take you off it at any time, or delete your account. ### Usage analytics We use Google Analytics 4 to see how Mix Chops is used, such as which pages and exercises people open, how far they get, scores and which features they use. Google Analytics uses cookies and collects information like your approximate location (country or city), device, browser and the page that referred you. We don’t send it your email address, name or account details. See [how Google uses information from sites that use its services](https://policies.google.com/technologies/partner-sites). To measure new account sign-ups, we also keep the time and method of a sign-in attempt in your browser. It contains no email address or account identifier, is ignored after one hour, and is removed when you return from sign-in. We report a completed new sign-up and its method to Google Analytics. ### Error reports When something on Mix Chops goes wrong, such as a sound that won’t start, a track that won’t load or a sign-in link that has expired, your browser sends a short technical report: what failed, on which page and exercise, the site version, and your browser and country. A one-line summary goes to Google Analytics with the usage data, and the full report is stored with Cloudflare for 30 days so we can fix the problem. Reports never include your email address, name or account details (we strip anything that looks like one before storing it), we don’t store your IP address with them, and they don’t use cookies. They come to our own server, so blocking Google Analytics doesn’t stop them. ### Ask Dan, the AI mentor (only when you’re signed in) In the EQ, compression, balance and space exercises, Ask Dan is an AI mentor built on Dan’s teaching. When you’re signed in, it writes replies to what you tap or type. To write one, we send the exercise details to Anthropic, which runs the AI model: the exercise and level, what was played (the part or the song’s parts, its style, and the EQ, compressor, fader, pan, width, delay or reverb settings), your answer and what you tapped, how you’ve done in that exercise so far (and, from the ears panel on your profile and home page, how you hear each band across the EQ exercises), the conversation about the current question, and anything you type to Dan. We don’t send your name, email address or account details. To find the right part of Dan’s teaching, a short description of the moment (or your typed question) is also searched for in Dan’s Ask Dan knowledge base, which uses OpenAI to run the search. We keep a count of how many replies each account has had each day, so we can apply the daily limit, and a record of each reply: what Dan said, which moment it was for, which AI model wrote it and what it cost. Both are filed under a code that stands for your account, not your email address, name or account id. We don’t store what you type to Dan, though his reply may mention it. If you mark a reply not helpful (the thumbs-down beside it), we note that against the reply so we can improve it. Signed out, the drills show written coaching instead and nothing is sent. ### Mix Chops Pro billing (only if you subscribe) Pro is paid for through Stripe, which processes the payment for us. Your card details go straight to Stripe and are never sent to or stored by Mix Chops. Stripe keeps what it needs to bill you and to meet its legal obligations: your email address, payment method, billing details, invoices and payment history (see [Stripe’s privacy policy](https://stripe.com/privacy)). On your account we keep a billing record: the Stripe customer and subscription it belongs to, your plan (monthly or yearly), its status and dates (when your trial or paid period ends, and whether it’s set to cancel), and whether you’ve had the free trial. So that each card gets one free trial, we also keep the card’s fingerprint, a code from Stripe that tells two cards apart without revealing the card number, with the account that used it for a trial. ### Your own songs (Pro, only if you upload) With Pro you can upload a song to train on. The file is sent to StemConsole (stemconsole.ai), an audio service also run by Dan Murtagh, which splits it into parts (vocals, drums, bass and so on) and stores the song and its parts for about 90 days, then deletes them. Mix Chops keeps your list of songs: each song’s title, when you added it, its length and its bar lines, and that you confirmed you have the right to use it, filed under a code that stands for your account, not your email address, name or account id. Your songs are private to your account. ### Emails When you make an account, or sign up for emails such as the EQ cheat sheet, your email address (and first name, if you gave one) is added to Dan Murtagh’s mailing system (the same one used for danmurtagh.com), which sends ear training tips, new exercises and Mix Chops news through Resend. Every email has an unsubscribe link. Unsubscribing stops the emails and leaves your account as it is. ### What we don’t collect No card numbers (Stripe handles payment), no microphone or recordings (Mix Chops never asks for your microphone; the music streams from our site and is processed in your browser), no precise location, no contacts and no advertising identifiers. ## 2. How we use it - To run your account and sync your progress between devices. - To send you sign-in emails, and emails with ear training tips, new exercises and Mix Chops news (unsubscribe anytime). - To understand how Mix Chops is used and improve the exercises. - To write Ask Dan’s replies when you’re signed in, apply the daily limit on them, and check their quality and cost. - If you subscribe to Pro: to bill it, give your account Pro, allow one free trial per account and per card, and handle cancellations and refunds. - If you upload your own songs: to split them and let you train on them, and to apply the monthly limit. - To keep the service secure and prevent abuse. - To meet our legal obligations. For visitors covered by the GDPR, we rely on the performance of our service to you (your account and progress, a Pro subscription and your songs), our legal obligations (billing and tax records), your consent (emails you signed up for), our legitimate interest in telling account holders about Mix Chops (emails to accounts, which you can unsubscribe from at any time) and our legitimate interest in understanding and securing the site (analytics and security logs). ## 3. Who handles it for us We use these service providers to run Mix Chops. They process information on our behalf and not for their own marketing. | Provider | What for | Where | | --- | --- | --- | | Supabase | Accounts and saved progress | Sydney, Australia | | Google | Google sign-in (if you use it), Google Analytics, web fonts | United States and elsewhere | | Cloudflare | Hosting, security, delivering the site, storing error reports and your list of uploaded songs | Global network | | Stripe | Taking payment for Pro: checkout, subscriptions, invoices and the billing portal (subscribers only) | United States and elsewhere | | StemConsole | Splitting songs you upload into parts, and storing them for about 90 days (Pro, only if you upload). Run by Dan Murtagh | Global network (Cloudflare) | | Anthropic | Writing Ask Dan’s replies in the exercises (signed in only) | United States | | Supabase (Ask Dan) | Dan’s Ask Dan knowledge base, searched for an Ask Dan moment or question (signed in only) | Tokyo, Japan | | OpenAI | Turning that moment or question into the knowledge-base search (signed in only) | United States | | Resend | Sending emails | United States | | jsDelivr | Delivering the sign-in software to your browser when you sign in | Global network | Some of these providers operate outside Australia, so information may be processed overseas. We choose established providers with published security and privacy commitments. We don’t sell or rent your personal information, and we don’t share it with advertisers or data brokers. We may disclose information if the law requires it. ## 4. How long we keep it - **Your account and progress:** until you delete your account. It’s then removed straight away, apart from database backups, which roll over within 7 days. - **Analytics:** kept by Google Analytics for up to 14 months. - **Error reports:** 30 days (the summary in Google Analytics, up to 14 months). - **Ask Dan:** each reply’s record is deleted after about 30 days, the daily reply counts after about 7. They’re filed under a code rather than your account, so deleting your account doesn’t remove them sooner. - **Pro billing:** your billing record until you delete your account. Stripe keeps payment and invoice records as long as tax and financial law requires. A card’s trial fingerprint is kept after an account is deleted, without the account, so deleting and signing up again doesn’t bring the free trial back. - **Your own songs:** the song and its parts for about 90 days at StemConsole; the list of your songs until you ask us to delete it. - **Emails:** until you unsubscribe. Deleting your account doesn’t unsubscribe you: use the link in any email, or ask at dan@mixchops.com. - **Your first name:** until you clear it on your profile page or the ear test result, sign out of that browser, or delete your account. - **Progress in your browser:** until you clear it. ## 5. Your choices and rights - **Change or remove your first name** on your [profile page](https://mixchops.com/me#account) or the [ear test](https://mixchops.com/ear-test) result. - **Delete your account** from your [profile page](https://mixchops.com/me#account). It removes your account and saved progress from our servers. - **Stop analytics** by blocking cookies for mixchops.com or using a browser or extension that blocks Google Analytics. The exercises still work. - **Access or correct** the personal information we hold about you, or ask any privacy question, by emailing [dan@mixchops.com](mailto:dan@mixchops.com). We reply within 30 days. If you’re in the EEA or UK you may also ask us to restrict or stop processing, request a copy of your data in a portable format, or withdraw consent at any time. You can complain to your local data protection authority. ## 6. Security Information is encrypted in transit and at rest. Account data is protected by database rules that let each person read and change only their own progress. No system is perfectly secure, so we can’t guarantee it. If a breach is likely to cause you serious harm, we’ll notify you and the Office of the Australian Information Commissioner as the Notifiable Data Breaches scheme requires. ## 7. Children Mix Chops isn’t directed at children under 13, and children under 13 shouldn’t create an account. If you believe a child under 13 has given us personal information, email us and we’ll delete it. ## 8. Changes If we change this policy we’ll update the date at the top, and for significant changes we’ll let signed-in users know on the site. ## 9. Contact and complaints Dan Murtagh, Melbourne, Australia. Email [dan@mixchops.com](mailto:dan@mixchops.com). If you’re not satisfied with our response to a privacy concern, you can complain to the [Office of the Australian Information Commissioner](https://www.oaic.gov.au) (1300 363 992).
