Privacy Policy for LearnToSpeakDrum

Last Updated: March 1, 2026

This Privacy Policy explains how LearnToSpeakDrum ("we", "us", "our") collects, uses, and stores information when you use https://learntospeakdrum.com and related services.

1. Information We Collect

1.1 Account and Authentication Data
- Email address (required for sign-in and account access)
- Name and profile image (if provided by your sign-in provider, such as Google)
- Authentication/account identifiers used by our auth system

1.2 Practice and Product Data
- Practice Hub items and scheduling data (for example: titles, groove content, due dates, review history, ratings, intervals, and repetition metrics)
- GrooveLab and Playground progress/session data (for example: levels, attempts, ratings, duration, and progression state)
- App settings you choose (for example: practice item limits and groove preferences)

Important note about anonymity:
Practice data is not fully anonymous in our production app because it is linked to your account/user ID so your progress can be saved and restored. We may create aggregated or de-identified statistics for product improvement.

1.3 Billing and Transaction Data
- Subscription/payment status and related customer identifiers
- We do not store full payment card numbers on our servers

1.4 Technical Data
- Basic request/device data and cookies/session data needed for security, login, and app functionality

2. Services and Processors We Use

We use third-party services to run the product:
- Auth.js / NextAuth for authentication flows and session handling
- Google (OAuth) when you choose Google sign-in
- Resend (email infrastructure) for email-based sign-in links and transactional email delivery
- MongoDB (database) to store account, practice, and progress data
- Stripe for payments, subscriptions, customer billing, and portal/checkout flows

These providers process data on our behalf or as independent controllers depending on the service. Your use of their services may also be subject to their own privacy terms.

3. Why We Use Your Data

We process data to:
- Authenticate users and secure accounts

- Process payments/subscriptions and provide purchase access
- Provide support, service updates, and important account notices
- Monitor reliability, prevent abuse, and improve the product

4. Legal Bases (where applicable)

Depending on your location, we rely on one or more legal bases:
- Performance of a contract (providing the service you requested)
- Legitimate interests (security, fraud prevention, product improvement)
- Consent (where required, such as certain cookies/emails)
- Legal obligations (tax, accounting, compliance)

5. Data Sharing

We do not sell your personal data. We share data only as needed with:
- Infrastructure and service providers listed above
- Professional advisors or authorities when legally required
- Successor entities in a merger, acquisition, or asset transfer (with safeguards)

6. Data Retention

We keep data for as long as needed to provide the service, comply with legal obligations, resolve disputes, and enforce agreements. Retention periods can vary by data type (account, billing, practice history, logs).

Depending on your location, you may have rights to:
- Access your data
- Correct inaccurate data
- Delete your data
- Object to or restrict certain processing
- Data portability

To request these, contact: support@learntospeakdrum.com

8. Security

We use reasonable technical and organizational safeguards to protect your data. No method of transmission or storage is 100% secure, so we cannot guarantee absolute security.

9. Children

LearnToSpeakDrum is not directed to children under 13, and we do not knowingly collect personal data from children under 13.

10. International Transfers

Your data may be processed in countries other than your own, depending on where our providers operate. We use appropriate safeguards where required by law.
