1. Scope
This Privacy Policy explains how Anchor (“Anchor,” “we,” “us,” or “our”) processes information when you use the Anchor iPhone or iPad app, App Clip, widgets, website, NFC fallback pages, support channels, and related features.
Some Anchor features are provided by Apple, including App Store purchases, iCloud, CloudKit, Apple Health, Family Controls, Managed Settings, notifications, alarms, App Clips, and Universal Links. Apple processes information under its own terms and privacy policies.
2. Information stored on your device
Anchor stores detailed routine information locally on your device using Apple platform storage, including SwiftData and UserDefaults. Depending on how you use the app, this may include:
- habit names, types, goals, units, schedules, reminder settings, and start dates;
- NFC object names, random tag identifiers, pairings, roles, and recent verification information;
- habit logs, progress, streaks, completion sources, and consistency calculations;
- focus-mode state, alarm configuration, wake-verification state, and app preferences;
- widget snapshots and limited shared app-group data needed to display widgets or coordinate extensions; and
- diagnostic state used by Anchor’s in-app System Health tools.
Older local Anchor data may be imported once during a storage migration. Anchor may let you export certain data using features available in the app. Local information generally remains on your device until you edit it, delete it, remove app data, or uninstall the app, subject to device backups and Apple platform behavior.
3. NFC tag information
When you pair a compatible tag, Anchor writes a Universal Link containing a random UUID. The public tag does not contain your habit name, progress, alarm name, health information, selected applications, Circle membership, or profile information.
A person who scans a tag without your Anchor setup may see a generic Anchor fallback page or App Clip experience. The public website does not use the tag identifier to reveal whether a tag is registered, who owns it, or which action it represents.
Tag URLs should still be treated as functional identifiers. Do not intentionally publish them, place tags where they can be tampered with, or use tags for sensitive access control.
4. Apple Health
Apple Health access is optional. If you select Apple Health as the source for a walking habit, Anchor may request read-only step access and use step totals to calculate progress for that habit.
Anchor does not write raw Health samples to NFC tags, show raw Health samples to Momentum Circle members, or use Health information for advertising. If a walking habit contributes to a Momentum Circle, its progress may affect your weekly percentage, but the raw step count and the habit’s identity are not shared with Circle members.
You can review or revoke Anchor’s Health access in Apple Health or iOS Settings. Revoking access may prevent Health-based walking progress from updating.
5. Screen Time and Family Controls
Screen Time features are optional. When you use Apple’s Family Activity Picker, Apple returns opaque tokens representing the apps, categories, or websites you selected. Anchor can apply your chosen restrictions without receiving ordinary human-readable app-selection names.
These opaque selections and related focus configuration are used to provide the feature you requested. They are not written to NFC tags or shared with Momentum Circle members.
6. Notifications and alarms
If you grant permission, Anchor uses notification and alarm frameworks to provide reminders, timers, wake-up alerts, retries, and related user-configured experiences. The app processes the schedules, sound choices, tag requirements, and status information needed to provide those features.
Apple controls final notification and alarm delivery. Your device settings, Focus state, power state, iOS version, and permissions may affect behavior.
7. Momentum Circles and iCloud
Momentum Circles are optional and use Apple CloudKit with your iCloud account. A Circle may store:
- the Circle name;
- your chosen display name;
- your current and previous weekly momentum percentages;
- timestamps and records needed to synchronize membership; and
- CloudKit sharing records and identifiers required by Apple.
Invited Circle members can see the Circle name, member display names, and shared weekly momentum percentages. They cannot see your habit names, individual completion events, tag links, alarms, selected apps, or raw Health data through the Circle.
Circle invitations are not publicly discoverable through Anchor. Recipients need Anchor and an eligible iCloud account. Apple processes CloudKit data under Apple’s terms, account settings, infrastructure, and retention practices.
8. Purchases and RevenueCat
Apple processes Anchor+ payments through StoreKit and the App Store. Anchor uses RevenueCat to validate purchases, manage subscription and lifetime access, restore purchases, and understand purchase and paywall performance.
RevenueCat processes a randomly generated anonymous app customer identifier, purchase history, transaction and subscription status, entitlement information, and app, device, and store metadata such as app version, operating system, locale, and currency. Anchor does not supply a name, email address, or Circle identity as the RevenueCat customer identifier.
Anchor does not send habit names, detailed habit progress, Health data, Circle identity, selected blocked apps, or advertising identifiers to RevenueCat. Purchase information is used for app functionality and purchase analytics, not cross-app advertising tracking.
Apple handles payment information; Anchor and RevenueCat do not receive your full payment-card details through in-app purchases. Manage or restore access in Anchor’s Settings, and manage subscriptions and refunds through Apple. For more information, see RevenueCat’s Privacy Policy →.
9. Website information
When you visit the Anchor website, the browser and hosting provider may process standard technical information such as IP address, browser type, device type, requested URL, referring page, approximate region, request date and time, and security or delivery logs.
The website does not use advertising trackers or cross-site behavioral profiling. If privacy-friendly performance analytics are added in the future, this policy will be updated before that collection begins.
Individual NFC fallback pages are intended to explain the product and open Anchor. They should not expose raw tag identifiers in page content or analytics events.
10. Support communications
When you contact support, we receive the email address, message, attachments, and other information you voluntarily provide. We use this information to respond, investigate problems, prevent abuse, improve support materials, and maintain records where reasonably necessary.
Do not send sensitive health details, passwords, full payment information, or unrelated private content. Anchor support may ask for your device model, iOS version, app version, and the steps that led to a problem.
11. Information Anchor does not sell
Anchor does not sell personal information. Anchor does not share personal information for cross-context behavioral advertising and does not use your habit data, Health information, or NFC activity to build advertising profiles.
12. Why information is processed
Anchor processes information as needed to:
- provide the app, App Clip, widgets, website, and support;
- connect NFC identifiers to actions configured on your device;
- calculate and display progress, streaks, patterns, and insights;
- provide user-configured reminders, focus sessions, and alarms;
- provide optional Apple Health, Screen Time, and Momentum Circle features;
- display, process, verify, and restore purchases, and understand purchase and paywall performance;
- diagnose failures, maintain reliability, prevent abuse, and protect security; and
- comply with applicable legal obligations.
13. Legal bases
Where applicable law requires a legal basis, processing may rely on performance of our agreement with you, your consent, legitimate interests in operating and securing Anchor, and compliance with legal obligations. When processing depends on consent, you may withdraw it through the relevant Apple permission controls or by discontinuing the optional feature. Withdrawal does not affect processing that was lawful before withdrawal.
15. Data retention
- Local app data generally remains until you change or delete it, remove app data, or uninstall Anchor, subject to backups and platform behavior.
- CloudKit Circle information remains while associated Circle, sharing, or member records exist, subject to Apple’s systems and deletion behavior.
- Purchase records and the related RevenueCat customer identifier may remain after uninstalling Anchor so access can be verified or restored and for fraud prevention and applicable recordkeeping obligations. Contact support for purchase-data privacy requests; Apple’s billing records remain subject to Apple’s controls.
- Support correspondence is retained only as reasonably necessary for support, safety, legal, and recordkeeping needs.
- Website security and delivery logs are retained according to the hosting provider’s operational schedule.
We do not state exact retention periods where they depend on user choices, Apple or RevenueCat systems, hosting providers, or the nature of a support or legal matter.
16. Security
Anchor uses reasonable technical and organizational safeguards appropriate to the information and product architecture. These include keeping detailed routines on the device, separating NFC identifiers from public habit details, relying on Apple security controls for sensitive permissions, and limiting optional Circle sharing.
No device, network, transmission, or storage system can be guaranteed perfectly secure. Keep your device protected, install trusted operating-system updates, and avoid placing NFC tags where others can replace or misuse them.
17. Your choices and controls
You can:
- complete ordinary habits without NFC;
- decline or disable notifications and alarms;
- decline or revoke Apple Health access;
- decline or revoke Screen Time authorization;
- avoid creating or joining Momentum Circles, leave a Circle, or manage iCloud access;
- manage or cancel subscriptions through your Apple Account;
- edit or delete local habits, tags, alarms, and progress using available app controls;
- remove local app data by deleting it through available controls or removing the app; and
- contact support with privacy questions.
18. Children’s privacy
Anchor is not directed to children under 13 or the minimum digital-consent age required in their region. We do not knowingly collect personal information from children in violation of applicable law. A parent or guardian who believes a child provided personal information through support or the website may contact us.
19. International processing
Apple, RevenueCat, hosting providers, and other service providers may process information in countries other than the country where you live. Where required, transfers are handled using protections recognized by applicable law. Apple’s and RevenueCat’s processing locations and transfer mechanisms are governed by their respective policies and agreements.
20. Regional privacy rights
Depending on where you live, you may have rights to request access, correction, deletion, restriction, objection, portability, withdrawal of consent, information about processing, or an appeal. You may also have the right to contact a local data-protection authority.
Much of Anchor’s detailed data is stored only on your device or within your personal iCloud context and may not be accessible to us. In those cases, we may provide instructions for using device, app, or Apple account controls instead of directly retrieving or deleting the information.
21. Changes to this policy
We may update this Privacy Policy as Anchor changes. The “Last updated” date will show when revisions were made. If a change materially affects how information is handled, we may provide additional notice through the app or website where appropriate.
