This Privacy Policy explains how ODISEI MUSIC S.L. ("we," "us," or "our") collects, uses, stores, protects, and shares your personal information when you use the Odisei Play web or mobile application and related services (collectively, the "App").
ODISEI MUSIC S.L. is a Spanish company with CIF/NIF B67566026, located at DOCTOR MURILLO, 10, SANT CUGAT DEL VALLÉS (BARCELONA), 08172, SPAIN.
For any questions about this Privacy Policy or your personal information, please contact us at: support@odiseimusic.com
Your microphone audio stays on your device.
Odisei Play listens to your instrument to read pitch and timing, and it does that analysis on the device itself. We never upload, transmit, or store that audio. It does not leave your device, and no one at Odisei Music can listen to it.
1. Information We Collect
We collect information to provide and improve the Odisei Play App and your music learning experience. The types of information we collect include:
• Account Information: When you register for an account, you voluntarily provide your name, email address, username, and optionally, password. We also create a user ID for your account, which we use to link your data across the App and our providers.
• Music Learning & Practice Activity Data: We collect data related to your practice sessions and music learning progress, including MIDI information about notes played, notes missed, and related performance metrics. This data is collected to provide you with a personalized experience, usage statistics and to track your progress.
• Usage Data (App Interactions): We collect information about how you interact with the App, including the features you use, the buttons and screens you open, the amount of time you spend in the App, and your progress through lessons and exercises. This helps us better understand global user behavior and improve the App for everyone.
• Photos: If you choose to set a profile picture, or to upload an image while using our content tools, we collect the image you pick and store it with your account. We only read the photos you select. We never browse your photo library.
• Device Information and Device Identifiers: We collect information about the device you use to access the App, such as the device type, operating system, app version, and unique device identifiers. If you allow notifications, we also collect a push token, which identifies your device so we can send you a notification through our provider OneSignal.
• IP Address and Approximate Location: We collect your IP address, which is a numerical label assigned to your device by your internet service provider. Our analytics provider, PostHog, derives an approximate location from it, at country and city level. We do not collect GPS or precise location. On older versions of Android, the system may ask for location permission before it lets the App scan for Bluetooth instruments. We use that only to find your instrument, never to work out where you are.
• Crash Logs and Diagnostics: When the App hits an error or crashes, we collect a crash report: the error, the stack trace, the app version, and basic device and performance information. We use these reports to fix the App.
• Audio Input Data: When you use the App's learning and practice features, the App processes audio from your device's microphone to analyze your performance (for example pitch, rhythm, and dynamics) and give you real-time feedback and scoring. This analysis runs on your device. The audio is never uploaded, transmitted, or stored, and we never receive it. We keep the result of the analysis, such as the notes you played and missed, as practice activity data.
• Payment and Transaction Information (Purchase History): When you subscribe to Paid Content or purchase in-app coins, we collect information necessary to process your transactions and manage your access to features, via our third-party provider, RevenueCat. This includes details of your subscription plan, purchase history, and the type of content unlocked. We do not collect or store your payment card details. On mobile, Google Play or Apple collects and processes them; on the web, our payment processor Stripe does. Your purchase history is linked to your user account so we can give you what you paid for.
2. How We Collect Your Information
We collect information in the following ways:
• Directly from You: We collect personal data like your name, username, and email address when you voluntarily register for an account.
• Automatically: We automatically collect music learning & practice activity data, usage data, device information, device identifiers, crash logs, diagnostics and IP address as you use the App.
• From Your Device, With Your Permission: The App asks your permission before it uses the microphone, opens your photo library, or sends you notifications. You can refuse, and you can change your mind later in your device settings. Refusing the microphone or notifications turns off the features that need them; the rest of the App keeps working.
3. How We Use Your Information
We use the information we collect for the following purposes:
• To personalize your music learning experience and provide tailored content.
• To track your progress and provide you with statistics and insights into your practice regularity and musical development.
• To provide, operate, maintain, and improve the Odisei Play App and its features.
• To communicate with you about your account, updates, and support inquiries.
• To provide technical support and troubleshoot issues.
• To detect, diagnose and fix crashes and errors, using crash logs and diagnostics.
• To send you the notifications you asked for, such as practice reminders, if you allowed them.
• For analytics and research to understand user engagement, identify trends, and improve the App's functionality and content.
• To ensure the security and integrity of the App.
4. Cookies, Analytics, Session Replay and Error Tracking
We use PostHog, an analytics platform, to see how the App is used and where to improve it. PostHog receives your app interactions and other actions you take in the App, your device identifiers, your crash logs and diagnostics, and your IP address, from which it derives an approximate location at country and city level. Before you sign in, this data is tied to a device identifier. Once you sign in, we identify you in PostHog by your user ID, so the data is linked to your account. We do not use it for advertising, and we do not track you across other apps or websites.
Session replay. PostHog also records your session: your taps, your navigation, and the content of the screens you see. We watch these recordings to reproduce bugs and to find the screens that confuse people.
What a recording does and does not contain: text you type into a field is masked, and passwords are always masked. In the mobile app, images are masked too. Text that the App displays on screen is recorded as it appears, so personal information shown on a screen can appear in a recording, for example your email address on your account screen or the name of your device. Only our team and PostHog, acting as our processor, can watch these recordings, and we use them to fix and improve the App.
Error tracking. PostHog captures uncaught exceptions and unhandled rejections, together with the stack trace, the app version, and basic device information. We use these crash reports to fix the App. We do not send the contents of the App's console logs.
Our user data, including account information and practice data, is stored securely in a PostgreSQL database hosted by our third-party provider, Supabase.
5. How We Share Your Information
We value your privacy and do not sell your personal information in any ways. We only share your information to providers that allow us to serve the App's experience to you:
• Third-Party Service Providers:
We share information with third-party service providers who perform services on our behalf to support the operation of the App. This includes:
• PostHog for analytics, session replay and error tracking. We share your app interactions and other in-app actions, your device identifiers, your user ID, your crash logs and diagnostics, and your IP address, from which PostHog derives an approximate location. PostHog acts as our data processor and may not use this data for its own purposes.
• Supabase for database hosting and authentication (account information including your email address and user ID, usage data, practice data, and any profile picture you upload). Supabase acts as our data processor. Data stored with Supabase is used only for internal app operations and technical support by our team.
• OneSignal for push notifications, and only if you grant the notification permission. We share a push token and the matching device identifier, so OneSignal can deliver a notification to your device. If you never allow notifications, or if you turn them off, we share nothing with OneSignal.
• Netlify for web server hosting (relevant data for serving the web portion of the service, if applicable).
• RevenueCat for subscription management: When you make a purchase or subscribe, your purchase history and transaction details (excluding payment card data, which Google Play, Apple or Stripe handles directly) are shared with RevenueCat, and with the store that took the payment (Google Play on Android, Apple on iOS). This sharing is primarily for App Functionality (e.g., validating receipts, managing your subscriptions, and enabling access to purchased in-app content) and for Analytics (to understand purchase trends and improve our service through RevenueCat's dashboard features). This purchase history data is linked to your user account for the purposes of providing and improving the service. We do not use or share this data for tracking you across other apps or websites for advertising purposes
• Stripe payment processing: When you make purchases for Paid Content within the App on the Web, we utilize Stripe as our third-party payment processor. While we collect information required for billing, we do not directly collect or store your sensitive payment card details. Instead, this information is securely transmitted directly to Stripe for processing. Stripe acts as our data processor and is contractually bound to protect your information and use it solely for the purpose of facilitating your payments. We receive transaction-related data from Stripe to confirm and validate your purchases.
These providers are contractually obligated to protect your information and use it only for the purposes for which we provide it.
• Internal Use: Your data, including practice statistics, is used internally by our team to improve the App and provide technical support. Some data is shared back to you within the App to show your progress and statistics.
• Legal Requirements: We may disclose your information if required to do so by law or in response to valid requests by public authorities (e.g., a court order or a request from law enforcement).
• Business Transfers: In the event of a merger, acquisition, or sale of all or a portion of our assets, your information may be transferred to the acquiring entity.
Important Notes:
We explicitly state that we do NOT share your data with Tency Music. Our collaboration with Tency Music is solely based on licensing their content for use within the App, as described in our Terms of Use.
We do NOT share your data for marketing or advertising purposes with any third parties.
We do NOT share audio from your microphone with anyone. It never leaves your device.
6. Data Security
We take reasonable measures to protect your personal information from unauthorized access, use, alteration, and disclosure. Every connection the App makes, to us and to the providers named above, uses HTTPS, so your data is encrypted in transit. We use secure authentication provided by Supabase and store data in their secure cloud infrastructure. However, no method of transmission over the internet or electronic storage is 100% secure, and we cannot guarantee absolute security.
7. Data Retention
We retain your personal information for as long as necessary to provide you with the App's services and fulfill the purposes outlined in this Privacy Policy. We may also retain data for a longer period if required by law or for legitimate business purposes. The data will be deleted after 30 days of the user deleting its account. Section 8 explains how to delete your account.
8. Deleting Your Account and Your Data
You can delete your account and the personal data attached to it in two ways:
• In the App: open your profile, then Edit Profile, and use Delete Account. You have to type DELETE to confirm. This deletes your account straight away.
• On the web: go to
https://play.odiseimusic.com/delete-account and fill in the form. You do not need to be signed in to reach that page or to send the request. This files a request with us, and we handle it by hand.
Deleting your account deletes your account information, your profile picture, and everything attached to your account: your practice history, your progress, your goals, your awards, and your purchases. We remove this from our systems, including backups, within 30 days. We keep only what the law requires us to keep. There is no way to recover a deleted account.
Deleting your account does not cancel an active subscription. The store you bought it from manages that subscription, so cancel it there: use Manage Subscription in the App, or cancel from Google Play on Android or the App Store on iOS. Cancel before you delete your account, otherwise the store keeps charging you. If you need help, write to support@odiseimusic.com.
9. Your Data Rights
Depending on your location and applicable data protection laws (such as GDPR in Europe), you may have the following rights regarding your personal information:
• Right to Access: Request a copy of the personal information we hold about you.
• Right to Rectification: Request that we correct or update inaccurate or incomplete personal information.
• Right to Erasure ("Right to be Forgotten"): Request the deletion of your personal information, subject to certain exceptions (e.g., legal obligations). We will delete all your personal data from our systems, including backups within 30 days, unless there is a legitimate business interest to keep the data, such as to comply with legal obligations, to enforce agreements or to resolve disputes.
• Right to Restrict Processing: Request that we limit the ways in which we process your personal information.
• Right to Object to Processing: Request that we object to the processing of your personal information in certain circumstances.
• Right to Data Portability: Receive your personal information in a structured, commonly used, and machine-readable format and have the right to transmit that data to another controller.
• Right to Withdraw Consent: If we rely on your consent to process your information, you have the right to withdraw that consent at any time.
10. Exercising Your Rights
To exercise any of your data rights, please contact us by email at support@odiseimusic.com. We will respond to your request in accordance with applicable law.
11. Age Limitation
The Odisei Play App is only intended for individuals who are 18 years of age or older. We do not knowingly collect personal information from children under the age of 18. If you are under 18, please do not use the App or provide any information to us. If we become aware that we have collected personal information from a child under 18 without appropriate legal consent, we will take steps to delete that information as soon as possible.
12. Changes to this Privacy Policy
We may update this Privacy Policy from time to time. If we make material changes, we will notify you by email or through a prominent notice within the App when you next open it, detailing the changes. Your continued use of the App after being notified of the changes will constitute your acceptance of the revised Privacy Policy.
