Mindkeep Privacy Policy

Screen Time and local app data

Apple's private Family Activity Picker represents selected applications, categories, and websites with opaque tokens. Mindkeep stores those tokens but does not receive their underlying application, category, or website identities from the picker. Apple documents this privacy-preserving picker at https://developer.apple.com/documentation/familycontrols/familyactivitypicker.

Mindkeep also handles the number of opaque selections; aggregate duration and threshold events for selected activities; the daily allowance and rescue preference; Screen Time authorization and monitoring state; daily success, missed, repair, and rescue outcomes; and island progress, Keeper choice, and accessibility preferences.

Selections, settings, monitoring state, outcomes, and island progress are stored locally in the Mindkeep App Group, including a local SQLite day ledger. Aggregate usage is rendered inside Apple's report extension; it is not written to the day ledger or exported to the main app. These local records provide the allowance, shield, rescue, repair, activity report, recovery, and island progression you see. Mindkeep does not transmit opaque Screen Time selection tokens, the identities of selected apps, usage reports, or full day records to the developer, RevenueCat, PostHog, or Appstack. Limited analytics events include selection counts, choices, and action or outcome categories; they do not upload the local day ledger.

Subscriptions and RevenueCat

Apple processes in-app subscriptions. Mindkeep uses RevenueCat to check subscription status, validate purchases, restore access, prevent fraud, and understand subscription performance. The app connects to RevenueCat to load subscription options and check access, including before you make a purchase. An internet connection is needed to purchase or restore and to refresh subscription information.

RevenueCat processes purchase history and subscription status, such as product and transaction identifiers, purchase and renewal dates, expiration, and refunds. It also receives a randomly generated anonymous app user ID and technical information needed to provide its service, such as app and operating-system versions, device type, locale, and currency. Purchase information is available to the publisher through RevenueCat's subscription dashboard for app functionality and subscription analytics.

Mindkeep does not require an account or send a name, email address, phone number, or Apple's advertising identifier (IDFA) to RevenueCat. RevenueCat's anonymous app user ID is linked with Appstack and PostHog installation identifiers and acquisition information so subscription activity can be connected with product analytics and purchase attribution. These identifiers are pseudonymous and allow the services to recognize the same installation. Apple handles your payment details; Mindkeep and RevenueCat do not receive your payment card or bank account details. RevenueCat processes subscription information on the publisher's behalf.

Advertising and sharing

Mindkeep displays no in-app ads. Mindkeep uses PostHog for product analytics and Appstack for acquisition and purchase attribution. These services help us understand onboarding, subscription conversion, feature use, and whether actions succeed or fail. They receive explicitly recorded screen views and actions, predefined choices and counts, and fixed result or error categories. Examples include a chosen daily allowance, the number of selected activities, a permission result, and whether protection activation succeeded.

PostHog and Appstack also receive installation identifiers and app or device technical information, such as app and operating-system versions and device type. Appstack uses Apple Ads attribution to measure which Apple Ads campaign led to an installation. Attribution information and subscription activity can be linked using the identifiers described above. These services process this information for Mindkeep's analytics and attribution.

The app does not include Screen Time tokens, selected app names, detailed usage reports, full day records, free-text input, or raw error messages in analytics events. Session replay is disabled, and this integration does not collect IDFA. The integration is configured for product analytics and acquisition measurement, with no cross-company advertising targeting configured.

Backups, retention, and deletion

Depending on your device settings, iOS may include locally stored Mindkeep data in iCloud or computer backups. Device transfer and restore follow Apple's controls and your choices. Mindkeep does not operate a cloud sync or backup service and cannot access your backups.

Local settings, opaque tokens, day records, and island progress remain until you delete Mindkeep. Choose Delete App, not Offload App, in iOS Settings to remove local app data. Reinstalling without restoring a backup starts a new local experience. Restoring a device backup may restore Mindkeep data. To remove backup copies, use Apple's iCloud or computer-backup controls.

Deleting the app does not cancel your subscription or automatically erase purchase records held by Apple or RevenueCat, or analytics and attribution records held by PostHog or Appstack. Manage or cancel your subscription in your Apple account's subscription settings. Restore Purchases can restore eligible paid access after reinstalling; it does not restore island progress that was not backed up.

Subscription records are retained as needed to provide and restore access, handle support, prevent fraud, and meet applicable legal obligations. Analytics and attribution records are retained under the retention settings for Mindkeep's PostHog and Appstack accounts. You may request access, correction, or deletion of subscription, analytics, or attribution information held on the publisher's behalf by emailing support@usemindkeep.com. We may need limited purchase or installation information to locate the linked records and verify the request. Do not send payment-card details, passwords, or Screen Time reports. Some records may need to be retained for legal obligations or disputes; Apple controls its own purchase records.

Screen Time authorization

Authorization is requested for the individual using the device. You can withdraw it in Settings > Screen Time > Apps with Screen Time Access > Mindkeep, or in Mindkeep's per-app settings by turning off Screen Time Restrictions. Withdrawing authorization stops Mindkeep's Screen Time protection and the system lifts its restrictions. The app checks authorization again when it becomes active.

Mindkeep also provides Stop protection on the subscription screen and in Settings without requiring an active subscription. This stops Mindkeep's monitoring, clears its restrictions, and withdraws its Screen Time authorization without erasing your saved island progress.

Children and availability

Mindkeep uses individual authorization for a device owner. It is not a parent-monitoring service or a Kids Category app. It does not knowingly collect children's personal information. Apple and local storefront requirements control availability and subscription eligibility. If you believe a child has provided personal information, contact support@usemindkeep.com.

This support website

The support website is separate from the app and is hosted with Vercel. Visiting it sends ordinary browser and network requests to the hosting service so the pages can load. No Screen Time selections, usage reports, or day records are sent to this website by the app.

The website has no contact form, advertising, or added analytics. Opening an email link uses your email application; Mindkeep does not automatically attach or send app data.

Email support and privacy requests

If you email Luke McKnight, your email address, message, and attachments are received in the support inbox hosted by Namecheap Private Email and used to answer your request. This is separate from data stored locally by the app. Please do not include private Screen Time selections or usage reports.

Support correspondence is kept as needed to handle your request and retain a record of its resolution. To request deletion of support correspondence, email support@usemindkeep.com. Depending on where you live, you may have rights to access, correct, delete, or restrict processing of personal information. Contact the same address to exercise those rights.

Texting Luke and in-app surveys

Mindkeep may show a short card from Luke McKnight on Home at a few moments, such as your first morning, your third earned day, your first missed day, or when you stop protection. Your device decides whether to show a card from your island progress and day outcomes; that information is not sent anywhere to make the decision. Each founder card appears at most once. A survey question may reappear on a later day until you answer or dismiss it, and Mindkeep shows at most one card a day.

If you tap Text me, Mindkeep opens Apple's Messages app with a text to Luke's Google Voice number already filled in. The filled-in text is a short greeting that may name the moment that showed the card, for example "hi Luke, about my first night with Mindkeep:". It never includes Screen Time or app usage data. You can change or delete it, and nothing is sent unless you send it yourself. Mindkeep does not read, store, or receive what you write. Mindkeep records only whether a card or survey was shown, dismissed, or tapped, as one of the product events described above.

Texts you send go to a Google Voice number and are read by Luke McKnight. He receives your phone number, your messages, and any attachments, and uses them to reply to you and to improve Mindkeep. If you agree to a phone call, your number and the call log are handled by Google Voice in the same way. Calls are not recorded. If you leave a voicemail, Google Voice records and stores it so Luke can listen to it, and it is handled like a text. Google provides Google Voice under its own privacy policy: https://policies.google.com/privacy. Your mobile carrier handles the text as it would any other. Please do not send private Screen Time selections, usage reports, or payment details.

Luke may keep short notes on what you said to guide product decisions. Your words will not be quoted publicly or used in marketing without your permission. Texts, call logs and voicemails are deleted within 12 months; notes are kept without your phone number. To have your texts and notes deleted sooner, reply "delete" or email support@usemindkeep.com. If Luke sends you an App Store offer code as thanks, Apple handles its redemption.

Mindkeep may also ask an occasional one-tap question, for example whether your island crossed your mind when you wanted to open a blocked app. Surveys are optional, can be dismissed, and have multiple-choice answers only, with no free-text field. If you answer, Mindkeep sends a product event named survey_answered that contains the survey's identifier and the identifier of the answer you chose. It is sent with the installation identifier described above, through the same PostHog and Appstack product-event pipeline as the other product events described above, and kept under the same retention settings.

Changes

This policy was updated October 13, 2026 to describe texting Luke from in-app cards and one-tap surveys. The October 9, 2026 update described PostHog analytics, Appstack attribution, linked installation and subscription identifiers, and the current support email address and provider. If Mindkeep's data practices change, this policy and its App Store privacy disclosures will be updated before the changed behavior is released.
