Privacy Policy

Last updated: 2 August 2026 · Notice version 2026-08-v1

This Privacy Policy explains how Frazer Music Limited (“we”, “us”, “our”) collects, uses, and protects your personal data when you join our waitlist or use Frazer at frazermusic.com (the “Service”). We are based in the United Kingdom and process data in accordance with the UK General Data Protection Regulation (UK GDPR) and the Data Protection Act 2018.

Frazer is in beta. Recording and feedback features are being switched on during the beta period; this policy describes them from the point they reach you, and we will tell you when a material change is made.

1. Data Controller

The data controller is Frazer Music Limited. You can contact us at hello@frazermusic.com.

2. What Data We Collect

Waitlist information

When you join the waitlist we collect your first name and email address, and the two preferences you tell us: roughly where you are on guitar, and whether you mostly play acoustic or electric. We may also record standard campaign attribution (such as the site that referred you). We use this to email you about the launch and to shape what we build first. You can unsubscribe at any time.

Account information

When you create an account we collect your email address and, optionally, your name and profile picture. Authentication is handled by Clerk (see Third Parties below). If you sign in with a social provider (Google, GitHub, etc.) we receive only the data that provider shares with Clerk.

Your age

We ask which age range you are in. We use it to decide whether your recordings may be used to train our coaching models — recordings from players under 18 are excluded from training. Everything else in the app works the same either way.

Practice recordings

When you use a recording feature, we record what you play — a “take”. We store the audio along with what you were playing at the time (the song, the step, the chords, the expected timing) and the conditions it was captured in (your microphone settings, whether you were on headphones, measured input latency, background noise level, device and browser).

Sound Check, including your room

Before your first recording we run a short Sound Check. It plays a calibration click and records it back to measure your audio latency, and it captures two short reference takes. The calibration click captures a short recording of your room, which we use to adapt the coach to your space. We are measuring acoustics, not listening to your surroundings.

Bug reports

If you send us feedback from inside the app, we receive your message, the screen you were on, and — if you record one — a short voice note and screen capture.

Usage and practice data

We store your in-app progress, practice history, XP and streaks so your data persists across devices. This data is associated with your account.

Product analytics

Inside the app we record which features you use — which songs and steps you open, how far you get through the Sound Check, whether a recording uploaded successfully — using PostHog, hosted on its European instance. These events are keyed to your account identifier, not your email address, and we do not run session recording, heatmaps or any advertising tracking. You can switch it off in the app’s privacy page. This marketing site itself runs no analytics.

Technical data

We may collect standard web server logs including IP address, browser type, and referring URL. Error reports may be captured via Sentry.

3. How We Use Your Data, and Our Legal Basis

To operate the waitlist and email you about the launch where you have consented (lawful basis: consent).
To provide and operate the Service, including giving you feedback on what you play (lawful basis: performance of our contract with you).
To save and sync your practice progress across devices (lawful basis: contract).
To train and evaluate our coaching models using your practice recordings, unless you opt out (lawful basis: legitimate interests — building a coach that hears playing accurately). This is never a condition of using Frazer, and turning it off costs you nothing in the app.
To understand how the product is used, so we can improve it (lawful basis: legitimate interests).
To diagnose technical errors (lawful basis: legitimate interests).
To send you transactional emails, such as account and waitlist confirmations (lawful basis: contract).
To send optional product update emails where you have consented (lawful basis: consent).

We do not use recordings to identify you, and we do not sell or share your data for anyone else’s purposes.

4. Human Review of Recordings

Recordings may be reviewed by professional guitarists engaged by us, under contract and confidentiality, through a controlled tool with no downloads. They listen so the coach learns to hear playing the way a teacher does — and sometimes so one of them can record you an answer.

If you opt out of helping improve the coach, your recordings are not put in front of a reviewer.

5. Third-Party Services

Clerk — identity and authentication. Processes your email address and social-login tokens. clerk.com/privacy
PostHog — product analytics in the app, on its EU instance. Receives feature-usage events keyed to your account identifier. posthog.com/privacy
Resend — email delivery. Processes your name and email address to send waitlist and transactional emails. resend.com/legal/privacy-policy
Cloudflare — CDN, DDoS protection, bot verification (Turnstile) on our forms, and R2 object storage where recordings are held. cloudflare.com/privacypolicy
Railway — cloud hosting provider where our backend and database run. railway.app/legal/privacy
Sentry — error monitoring. May receive stack traces that include anonymised request context. sentry.io/privacy
Stripe — subscription billing, if and when you subscribe to a paid plan. We never see or store your card details. stripe.com/privacy

Where any of these services are located outside the UK/EEA, transfers are covered by Standard Contractual Clauses or an equivalent adequacy mechanism.

6. Data Retention

Raw practice recordings: 12 months from the date they were recorded, then deleted.
De-identified training data: kept indefinitely. A recording is separated from your identity when it is stored, and once it has been combined into our training data it can no longer be traced back to you or pulled back out.
Bug-report voice notes and screen captures: 30 days.
Account and practice data: retained for the life of your account, plus up to 30 days after deletion to allow recovery.
Waitlist data: retained while you remain subscribed to launch updates, and removed when you unsubscribe or ask us to delete it.
Server logs: retained for up to 90 days.
Billing records: retained for 7 years to comply with UK financial regulations.

7. Your Choices and Your Rights

Turning off model training. There is a Help improve the coach switch in Settings. Turning it off stops your recordings being used for training from that moment. Recordings already combined into our training data cannot be pulled back out, but they are no longer linked to you. Nothing in the app stops working, and you keep your place in the beta.

Deleting your data. Ask us and we will delete your account, your recordings, your practice history, your analytics profile and your email contact record. Email hello@frazermusic.com with the subject “Delete my data” and we will complete it and confirm within 30 days.

You also have the right to:

Access — request a copy of the personal data we hold about you.
Rectification — ask us to correct inaccurate data.
Erasure — as described above.
Portability — receive your data in a structured, machine-readable format.
Restriction — ask us to pause processing in certain circumstances.
Objection — object to processing based on legitimate interests, including model training and product analytics.
Withdraw consent — at any time where processing is based on consent (e.g. marketing emails).

To exercise any of these rights, email us at hello@frazermusic.com. We will respond within 30 days. You also have the right to lodge a complaint with the UK Information Commissioner’s Office (ICO).

8. Cookies and Local Storage

We use a minimal set of cookies. We do not use advertising or tracking cookies.

Bot-verification cookie (set by Cloudflare Turnstile) — strictly necessary to protect our forms from automated abuse.
Authentication session cookie (set by Clerk) — strictly necessary to keep you logged in. Cannot be disabled without breaking the login flow.
Stripe cookie — set by Stripe’s checkout widget during payment. Strictly necessary for fraud prevention.

In the app we also use your browser’s local storage to keep your progress, your settings, and an analytics identifier. Our analytics sets no cookie, and you can switch it off in the app.

We do not use Google Analytics, Facebook Pixel, or any advertising tracking scripts.

9. Younger Players

Frazer is for guitarists, and plenty of guitarists are teenagers. The Service is not for children under 13, and we do not knowingly collect data from them. If you are 13 or over you can use Frazer normally — we simply exclude recordings from players under 18 from model training and from human review.

If you believe a child under 13 has provided us with personal data, contact us and we will delete it promptly.

10. Changes to This Policy

We may update this policy from time to time. When we make material changes we will update the “Last updated” date and the notice version above and, where appropriate, notify you by email. Every recording we hold is stamped with the notice version that was in force when it was made.
