Privacy Policy

Last updated: August 25, 2026

This Privacy Policy explains what information PureTone collects when you use the app, why it’s collected, and how it’s handled. It applies to the PureTone mobile application (“PureTone,” the “app,” or the “service”).

What PureTone is

PureTone is a classical-listening app. You choose a mood and an amount of time, and PureTone curates a listening session from a library of classical recordings, presented at 432 Hz. PureTone curates listening sessions and does not make medical or therapeutic claims.

Information you provide

When you create an account, PureTone collects the email address and password you provide. Your password is handled entirely by our authentication provider (Supabase Authentication) — PureTone does not store your password itself.

If you sign in with Apple, Apple may share your name and email with PureTone according to the permissions you grant at sign-in, subject to Apple’s own privacy terms.

Information generated by using the app

As you use PureTone, the following information is created and associated with your account:

What PureTone does not collect

PureTone does not use advertising or behavioral-advertising technology, does not collect device advertising identifiers, does not use third-party analytics or crash-reporting SDKs, does not access your device’s location, and does not collect payment information within the app (PureTone has no in-app purchases at this time).

How this information is used

Account, favorites, and listening data are used solely to operate PureTone’s core features: signing you in, remembering what you’ve saved, generating your listening sessions, and showing you a summary of your own listening. This information is not sold, and it is not shared with advertisers or used for cross-app tracking.

Where information is stored

Account, favorites, and listening data are stored using Supabase, a hosted PostgreSQL database provider. Access to this data is restricted at the database level so that each account can only read and write its own records. Session-generation requests are handled by PureTone’s own backend service. Depending on where you and PureTone’s service providers are located, information may be processed or stored in a country other than your own; where this occurs, it is handled under the same protections described in this policy.

We take reasonable, industry-standard measures to protect the information PureTone stores, but no method of storage or transmission is completely secure, and we cannot guarantee absolute security.

Data retention and deletion

PureTone retains your account, favorites, and listening data for as long as your account is active, so that these features continue to work. If you’d like your account and associated data deleted, contact us using the details below and we will process your request. In-app self-service account deletion is not yet available as of this policy’s last-updated date above; deletion requests made by contacting us will be honored.

Children’s privacy

PureTone is not directed at children under 13, and we do not knowingly collect information from children under 13. If you believe a child has provided us with personal information, please contact us and we will take appropriate steps to remove it.

Changes to this policy

We may update this Privacy Policy from time to time as PureTone changes. When we do, we’ll update the “Last updated” date at the top of this page. Continued use of PureTone after an update means you accept the revised policy.
