Privacy Policy

Effective date: July 22, 2026

App: Frequency (“the App”)

Provider: Transforma (“we”, “us”)

Summary

Frequency is a sound-therapy app. The App has no user accounts and asks for no name, email, or login. We do not sell your personal data, we show no ads, and we do not track you across other apps or websites. To understand and improve the App we collect a small set of anonymous, install-scoped usage analytics (described below), plus the minimum required to process a purchase (handled by Apple and our subscription provider). The optional mindful minutes you choose to write to Apple Health never leave your device.

What stays on your device (never sent to us)

The following is stored locally on your device (via iOS UserDefaults) and its content is never uploaded to our servers:

  • Favorites, recently played sessions, and listening time
  • Mood check-ins and mood history
  • Multi-day program progress
  • Playback queue, sleep-timer, and visualization preferences
  • Onboarding answers

Deleting the App removes this data. A reset option is also available in Settings.

Apple Health (optional)

If — and only if — you grant permission, the App writes mindful minutes to Apple Health when you complete a session. This data is written to your Health store on your device (and iCloud Health if you enable it), under Apple’s control. We do not read your Health data and it is never sent to us. You can revoke this permission at any time in iOS Settings → Health, or Settings → Privacy & Security → Health.

Purchases and subscriptions

When you buy a subscription or the lifetime unlock:

  • Apple processes the payment. We never see or store your payment details.
  • We use RevenueCat to validate and manage subscription status. RevenueCat receives an anonymous, app-generated user identifier and the transaction receipt/history needed to tell the App whether your “premium” entitlement is active. It does not receive your name or payment information from us. See RevenueCat’s privacy policy: https://www.revenuecat.com/privacy/

Anonymous usage analytics

To understand whether the App works well and to improve it, the App sends a small set of usage events to our own backend (no third-party analytics service is involved):

  • A random install identifier — a UUID generated on first launch and stored in UserDefaults. It identifies the installation, not you: it is not derived from your device hardware, your Apple ID, or any personal detail. Deleting the App deletes it; a reinstall starts with a fresh identifier.
  • Basic device context sent with that identifier: device model, OS version, app version/build, language (locale), and timezone.
  • Usage events: onboarding started/completed, paywall viewed, purchase started/completed/failed, restore, and audio session started/completed (including session duration). Events carry no free-text content, no mood data, no Health data, and no location.
  • The anonymous subscription identifier from RevenueCat, so purchase events can be reconciled with subscription status.

This data is stored on our servers and used only for analytics and product decisions. We do not sell it, do not share it with advertisers or data brokers, and do not use it to track you across apps or websites. To request deletion of the analytics data associated with your installation, contact info@transforma.pe.

What we do NOT do

  • No third-party analytics SDKs. The usage analytics described above go only to our own backend; no Google, Meta, Firebase, or similar analytics SDK is embedded in the App.
  • No advertising and no tracking. We do not use the Advertising Identifier (IDFA) and do not track you across apps or websites, so the App does not present an App Tracking Transparency prompt.
  • No microphone access. The audio visualizer reacts to the App’s own synthesized output; the App does not record or listen to you.

Children

The App is intended for a general audience and is not directed at children under 13. We do not knowingly collect personal data from children.

Your choices and rights

  • Stop all data collection (local and analytics) by deleting the App; local data can also be cleared with Settings → Reset.
  • Request deletion of the anonymous analytics data described above by writing to info@transforma.pe.
  • Manage or cancel subscriptions in iOS Settings → your name → Subscriptions.
  • For questions about subscription data held by our provider, contact us at info@transforma.pe.

Changes

We may update this policy; the “Effective date” above will change and the current version will always be available at the URL where you found it.
