Privacy Policy

Last Updated: October 18, 2025

This Privacy Policy explains how Tonic Sense collects, uses, and protects your information when you use the web application.

What Tonic Sense Does

Storage

Tonic Sense uses Supabase as a database to store:

  • Profile information required for login: your name, email address, and the date you joined
  • Lesson activity visible on your My Learning page:
    • What lessons you have practiced
    • When you last practiced a lesson
    • How many times you have practiced a lesson
    • What key signatures you have used for practicing piano lessons

Authentication

Tonic Sense uses Google and Apple for authentication so you can sign into the app through their platforms. Your name and email address in the Tonic Sense database are automatically updated if you have updated them in Google or Apple.

When you sign in with Google, Tonic Sense only accesses your basic profile information (name and email address). We do not access any other Google services or data from your Google account.

Tonic Sense's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

Hosting

Tonic Sense uses Vercel to host the website. Vercel collects website activity logs which include your user agent information. This helps troubleshoot bugs. No other information about you is visible through Vercel logs.

Email Communications

Tonic Sense uses the tonicsense.info@gmail.com email account to receive and reply to your emailed requests for beta access codes.

Data Security

Tonic Sense takes the security of your personal information seriously:

  • Secure Connections: All data transmitted between your browser and our servers is encrypted using industry-standard HTTPS/TLS protocols
  • Secure Database: Your data is stored in Supabase, a secure database platform that uses encryption and access controls to protect your information
  • Access Restrictions: User data is protected so that you can only access your own information. Other users cannot view your profile or lesson activity
  • Authentication Security: Account access is managed through Google and Apple's secure authentication systems

Data Retention

Your personal data (profile information and lesson activity) is retained for as long as your account is active. If you request deletion of your account, all of your data will be permanently removed from our systems and cannot be recovered.
