Privacy Policy

Drift

This policy describes how the mobile application Drift ("the App," "we," "us") handles information when you use it. Drift is a sleep and relaxation aid that plays calm word-based audio from files included in the app.

Summary

  • The App is designed to work without sign-in and without sending your usage or personal content to our servers for core functionality.
  • Word sequences are generated on your device with randomness; we do not receive lists of words you heard or session choices.
  • Audio you hear is played from assets bundled inside the app, not streamed from our backend during normal use.
  • If you choose to enter your name, it is used only for personalization. It stays on your device; we do not upload it to our servers and we never share it with third parties.
  • The App does not use the microphone for recording.

Who This Applies To

This policy applies to anyone who downloads and uses Drift on iOS or Android (and any other platform build we may offer).

Information the App Processes on Your Device

Session experience (local only)

  • Timer choice (e.g. 15 / 30 / 45 minutes or unlimited): used only in memory to end or fade a session; not uploaded by our code.
  • Shuffle / word order: computed locally from built-in word lists and random selection.
  • Mute and playback state: handled locally by the audio engine.
  • Optional display name: stored only on your device, used solely to customize your experience. We do not transmit this name to our servers, and we do not share it with advertisers, data brokers, or other third parties.

We do not operate in-app analytics, advertising SDKs, or account systems, and we do not intentionally transmit the above to our servers.

Audio

Playback uses pre-recorded files shipped with the App. The App does not call ElevenLabs or similar APIs at runtime.

Diagnostics

Standard operating system and store mechanisms (crash reports if you opt in on the device, Play/App Store processing) may apply according to Google and Apple policies.

Permissions and Device Capabilities

Audio playback

Play bundled voice clips and optional background playback so audio can continue when the screen is off.

Audio session / routing

Adjust how audio behaves with silent mode and other apps.

Android foreground service

Lets playback continue reliably when background playback is enabled; may show a media-style notification.

Keep screen awake

Reduces the chance the display sleeps mid-session; does not read personal data.

Haptics

Light vibration on supported devices when you interact with controls; no personal content.

Microphone

Not used for recording. We do not use the microphone to listen to you for any app features.

Data Sharing and Third Parties

  • We do not sell your personal information.
  • Apple and Google process data according to their roles as platform and store providers.
  • Expo / EAS may be used to build the App; that is a development and distribution pipeline, not ongoing collection of your in-app behavior by default.
  • If we add features that send data off-device, we will update this policy and ask for consent.

Retention and Security

Information that stays only on your device is removed when you uninstall the App or clear app data, subject to OS behavior.

We use reasonable practices when building and distributing the App; no method of storage or transmission is 100% secure.

Children

The App is intended for general audiences. If you are a parent and believe we have inadvertently collected personal information from a child in a way that violates law, contact us at hey@cognitiveshuffle.app and we will work to address it.

Your Rights

Depending on where you live, you may have rights to access, correct, delete, or restrict certain processing of personal data, or to lodge a complaint with a supervisory authority. Because the App currently minimizes data sent to us, many requests may be limited to what stores or OS vendors hold. Contact us and we will respond as required by law.

International Users

If you use the App outside the country where the publisher is based, your information may be processed in countries where we or our processors operate, including through app stores and cloud infrastructure they use.

Changes to This Policy

We may update this policy when the App or legal requirements change. The "Last updated" date at the top will change when we do.
