Privacy Policy
Last updated: October 9, 2026
This policy explains what information Kalman Music Lessons ("we", "us") collects and how we use it — both on this website and in our mobile app Read Between the Lines (the "App"). We've tried to write it in plain English rather than legalese.
The short version
- You can use the App as a guest — no name, no email, no sign-up.
- If you turn on the microphone, audio is analysed on your device to hear which note you played. It is never recorded, stored, or sent to us.
- We never sell your personal information.
- You can delete your account and data at any time.
What we collect
Account information
When you first open the App we create an anonymous guest account — a random identifier with no personal information attached. If you choose to create a full account so your progress follows you between devices, we also store your email address.
Learning progress
Levels completed, stars, XP, streaks, practice days, and which notes you tend to get right or wrong. We use this to run the App, sync your progress across your devices, and pick what to drill next.
Microphone
The App can listen while you play in order to check your pitch. This analysis happens entirely on your device, in real time. No audio is recorded, saved, or transmitted to us or anyone else. You can decline microphone access and still use the App.
Purchases
If you subscribe, the purchase is processed by Apple or Google — we never see or store your payment card details. We receive your subscription status (active / expired) via RevenueCat so the App knows to unlock premium features.
Advertising (free plan only)
Free users may see ads served by Google AdMob, which may use advertising identifiers. On iOS we ask your permission before any tracking; if you decline, you'll see non-personalised ads instead. Subscribers see no ads at all.
Usage & diagnostics
Basic, aggregated information about how the App is used and whether it's working correctly, so we can fix bugs and improve lessons.
Website
If you join our early-access list we store the email address you give us. Our website uses standard analytics and, where you consent, advertising measurement tags.
Group class questions and measurement
When you ask about a group class, we collect your name, email, optional phone, selected class, question and permission to reply. We use these details to answer your question and follow up about that class. Asking a question does not book a place or subscribe you to marketing. Our inquiry inbox uses Formspree; class inquiries may also be handled in our scheduling and program-management system. Campaign information and the originating page can accompany your inquiry.
We measure class-page visits, class choices, scheduler-link clicks, form progress and whether an inquiry was received. These events do not include the name, email, phone or question you enter. Campaign identifiers can be kept in this browser tab and passed to our scheduler so we can understand where class interest comes from. Where optional class advertising measurement is enabled, the class footer lets you allow or decline it. Google Ads, Meta and Reddit may then receive page and inquiry events with a random inquiry reference, rather than your written question. This class preference applies to those optional class advertising events.
For practice-room early access, you can join with just your email. If you choose to complete the optional questionnaire, we also collect your answers, including instruments, room needs, schedule, budget, membership interest, and any optional name, neighborhood, or written feedback you provide. We use these to plan the rooms, equipment, and availability, and send the opening updates and early-access offers you request. Draft answers are kept in your browser tab during completion and cleared after a confirmed submission; you can also clear them using the form. After a successful signup, this browser tab keeps your email and a signup reference so you can add optional answers without signing up twice. We record signup activity, selected preference categories and questionnaire progress in analytics, without sending your name, email, or written answers in those events. Campaign information and the page that brought you to the site may accompany your response.
Who we share it with
We use a small number of service providers, and only for the purposes above:
- Supabase — hosts our database and accounts.
- RevenueCat, with Apple / Google — subscription processing and status.
- Google AdMob — advertising for free users.
- Formspree — receives website class inquiries, practice-room email signups and optional questionnaire answers.
- Google Analytics — website engagement measurement; Google Ads, Meta and Reddit — optional class advertising measurement when enabled and allowed.
We do not sell your personal information, and we don't share it with anyone else except where required by law.
Your choices and rights
- Play anonymously — you're never required to give us an email.
- Delete your account — you can delete your account and its data from within the App, or by emailing us.
- Tracking — decline the iOS tracking prompt (or change it in iOS Settings) for non-personalised ads.
- Remove ads — subscribe to Premium.
- Access / correction / deletion — email us and we'll help; depending on where you live (e.g. the EU/UK or California) you may have additional statutory rights.
Children
The App is intended for a general audience and is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has given us personal information, contact us and we'll delete it. Younger students are welcome to learn with the App under the supervision of a parent, guardian, or teacher.
Keeping it safe & how long we keep it
Data is transmitted over encrypted connections and access is restricted to your own account. We keep your progress for as long as your account exists; when you delete your account, we delete the data associated with it.
Changes
If we make meaningful changes to this policy we'll update the date at the top and, where appropriate, tell you in the App.
