BrainShift Privacy Policy

Effective date: July 24, 2026 · Last updated: October 26, 2026

Overview

This Privacy Policy explains how Chipmunk Studio (“we,” “us,” or “our”) handles information when you use BrainShift.

This policy applies only to BrainShift. Other Chipmunk Studio apps, including Engage, have separate privacy policies.

BrainShift keeps your Screen Time and Health information, detailed activity history, user-authored Plans, Journal content, settings, and earned-time balances in local storage. Optional Apple system features and sharing are described below. BrainShift sends the limited product analytics described below and uses service providers for purchases and attribution. We do not operate accounts or a cloud database for BrainShift.

Information stored on your device

BrainShift may process and store the following information locally:

  • Screen Time activity and app, category, or website selections
  • Detailed focus-session history and earned screen-time balances
  • Settings, preferences, schedules, and challenge progress
  • User-authored Plans, Journal entries and titles, journal names, and journal preferences
  • A broad age band used for age-appropriate sleep guidance
  • Apple Health information you allow BrainShift to read, such as workouts, mindful sessions, steps, walking distance, and sleep

Screen Time reports are processed on your device; temporary report copies may be kept locally for up to 15 minutes. Screen Time data is never uploaded, used for advertising profiles, or included in analytics or support diagnostics.

Your Screen Time and Health information is processed on your device. Chipmunk Studio does not receive, store, or have access to this information.

If you enter your age during onboarding, BrainShift converts it into a broad age band. Your exact age and date of birth are not retained.

BrainShift only requests read access to Apple Health. It does not write information to Apple Health or use Health information for advertising.

You can manage Screen Time, Health, notification, microphone, and speech-recognition permissions through your device settings.

Journal, dictation, and Apple system features

Journal content is stored locally and is never included in product analytics or sent to a BrainShift server. Copy places an entry on this device’s clipboard, without Universal Clipboard sharing. Share passes the selected entry to the destination you choose, whose privacy practices apply.

The optional Speak feature uses your microphone for on-device dictation in Journal, habits, and to-dos. Audio is neither saved nor sent to a server. Keyboard languages are used only on your device to suggest dictation languages. System keyboard dictation follows your Apple settings.

Journal Writing Tools uses Apple’s system interface and processing settings; processing may occur on your device or through Apple’s services. Translate uses Apple’s system translation interface and may send selected text to Apple unless translation is performed offline. See Apple’s Apple Intelligence privacy information and Translation privacy information.

BrainShift makes relevant Plan and to-do information available to Siri and Shortcuts and indexes to-do metadata on your device for discovery. Apple’s settings and privacy practices apply.

Product analytics

We use Mixpanel to understand app usage and purchase flows and improve BrainShift.

Mixpanel may process:

  • A random identifier for your BrainShift installation, not linked to your name, an account, or an advertising identifier
  • Limited usage events, such as setup and permission choices, feature use, and purchase or subscription outcomes
  • Basic event details, such as feature type, outcome, subscription tier, session duration, difficulty, and reward amount
  • Technical information, such as app and operating-system versions, device model, and analytics software configuration

Analytics excludes your name, email address, account or advertising identifiers, Screen Time and Health data, Brain Health scores, and Productive Apps history. It also excludes content you create, including Plan and Journal text and names, dictation audio, keyboard languages, and support messages, as well as prices, transaction or product identifiers, and purchase error messages.

We limit analytics to selected app events, without personal profiles, session recordings, IP-based location, or cross-app tracking. Analytics is processed by Mixpanel’s EU-hosted service. Read Mixpanel’s Privacy Policy for more information.

Starting with BrainShift 1.0.8, when Share Product Analytics is enabled, we share a random app identifier with RevenueCat, our purchase service. This helps us connect app usage with our advertising and purchase results. We don’t share your name, email, Health data, selected apps or content you create for this purpose.

You can turn analytics off or on under Settings > Data Controls > Share Product Analytics. Turning it off stops new product analytics, clears local analytics tracking data, and requests removal of this link. Previously collected records aren’t automatically deleted. Purchases, restores and Plus access continue to work. Turning it back on resumes collection and records that choice.

Purchases and subscriptions

BrainShift offers purchases through Apple’s App Store. Apple processes your payment and billing information. Chipmunk Studio does not receive your payment-card or banking details.

We use RevenueCat to manage purchases and premium access. RevenueCat may process:

  • An automatically generated anonymous identifier
  • Purchase and subscription history
  • Product and entitlement information
  • App, device, and operating-system information needed to provide the service

We do not provide RevenueCat with your name, email address, Screen Time activity, Health information, focus history, or selected app lists.

RevenueCat helps us validate purchases, restore access, prevent fraud, and understand purchase performance. Read RevenueCat’s Privacy Policy for more information.

Apple Ads attribution

BrainShift may use Apple’s standard advertising attribution service with RevenueCat to determine whether an installation or purchase resulted from one of our Apple Ads campaigns.

We use this information only to measure the performance of Chipmunk Studio’s own App Store advertising. We do not use it to track you across third-party apps or websites, display third-party advertising, or build an advertising profile.

Support communications

If you contact us, we may receive your email address, the contents of your message, and any attachments or technical information you choose to provide. Before you send a support email, BrainShift may include editable device and app diagnostics; you can review and remove this information before sending.

We use this information only to respond to your request, investigate problems, and provide support. Support communications are normally deleted within 24 months after the request is resolved, unless we need to retain them longer for security, legal compliance, or dispute resolution.

Please do not send passwords, payment-card information, Health records, or Screen Time reports when contacting us.

How we share information

We may share limited information:

  • With Mixpanel to provide product analytics
  • With RevenueCat to manage purchases and Apple Ads attribution
  • With Apple for App Store purchases and platform services
  • When required by law or necessary to protect our users and legal rights

Service providers that process information for BrainShift, including Mixpanel and RevenueCat, are required to provide the same or equivalent protection described in this policy, use the information only to provide their services to us, and comply with applicable privacy law.

We do not sell your personal information. We do not share it for targeted advertising or track you across third-party apps and websites.

Apple separately handles information associated with the App Store, Apple Health, Screen Time, device permissions, and optional diagnostic sharing according to your Apple settings and Apple’s Privacy Policy.

Retention and deletion

BrainShift’s local information remains on your device until you remove it through the app or system settings, or uninstall BrainShift.

Deleting a Journal entry removes its content but keeps a daily reward record without that content to prevent duplicate rewards. Deleting a journal keeps its entries in All Entries. Device backups follow your system settings; deleting app data does not remove existing backups or shared copies.

Uninstalling BrainShift removes information stored in the app’s local storage according to iOS behavior. It does not delete information independently maintained by Apple, such as Apple Health records or App Store purchase history.

Mixpanel product analytics are retained for up to 12 months. Turning product analytics off or uninstalling BrainShift stops future transmission to Mixpanel but does not automatically delete analytics already sent.

Purchase information processed by Apple and RevenueCat is retained as necessary to validate and restore purchases, prevent fraud, comply with legal obligations, and resolve disputes.

You may contact us to request deletion of eligible information held by Chipmunk Studio, Mixpanel, or RevenueCat on our behalf.

Your rights and choices

Depending on where you live, you may have rights to access, correct, delete, restrict, or object to the processing of your personal information.

Chipmunk Studio cannot access or provide a copy of your locally stored Screen Time and Health information, detailed activity history, user-authored Plans, or Journal content. You can manage this information through BrainShift, your device settings, or by uninstalling the app.

You can stop future product analytics at any time under Settings > Data Controls > Share Product Analytics.

Mixpanel analytics are associated with a random installation identifier rather than your name or a BrainShift account. As a result, we may not be able to locate analytics records from your email address alone.

To submit a privacy request, email support@chipmunkstudio.com with the subject “BrainShift Privacy Request.”

Children’s privacy

If an age is entered during onboarding, BrainShift processes it on the device to select an appropriate age band. The exact age is discarded and is not transmitted to Chipmunk Studio.

We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe that a child under 13 has provided personal information to us, please contact us so we can review and delete it where appropriate.

Changes to this policy

We may update this policy when BrainShift’s features, service providers, or legal obligations change.

We will publish the updated policy on this page and revise the “Last updated” date. If a change materially affects how information is handled, we will provide additional notice where appropriate.
