REZONE PRIVACY POLICY
Draft for publication — complete the operator and contact details before publishing.
Last updated: 4 November 2026
WHO WE ARE AND WHAT THIS POLICY COVERS
ReZone is a heart-rate-zone and workout app for iPhone and Apple Watch. This policy explains how the native ReZone apps handle information when you track workouts, review training, change settings, or use optional connected features.
The operator responsible for ReZone is:
Legal name: [INSERT LEGAL NAME OF APP OPERATOR]
Address: [INSERT BUSINESS OR CONTACT ADDRESS]
Privacy contact: [INSERT PRIVACY EMAIL ADDRESS]
App information and support: https://daedalx.com/apps/rezone
In this policy, “we” means that operator. Apple’s services and any websites you visit have their own privacy terms. This policy covers the native app, rather than making claims about website cookies or hosting logs.
OUR APPROACH
ReZone does not require a ReZone account. The native app does not contain advertising, cross-app tracking, or third-party analytics SDKs. It does not upload your workout or health information to a developer-operated server. We do not sell or rent your personal information, use health information for advertising, or use it to create marketing profiles.
Processing information on your devices is different from sending it to us. ReZone needs to access and process health information locally to provide its features, but we do not receive that information through normal use of the app.
INFORMATION REZONE PROCESSES
Apple Health information
With your permission, the iPhone app can read workout history, workout dates and types, heart-rate samples, workout pauses, resting heart rate, VO₂ max, body mass, and running or cycling power where available. ReZone uses this information to calculate training-zone time, show progress and training summaries, and provide relevant training guidance. Availability depends on your devices, data sources, and permissions.
Workout recording on Apple Watch
With your permission, the Watch app can read and record workout information, including heart rate, active energy, walking/running distance, running speed, workout duration, and workout events. Completed workouts and associated measurements may be saved to Apple Health. Live readings are sent to your paired iPhone to display and control the workout. ReZone does not implement GPS route recording or upload location histories to us.
Information you enter
ReZone stores your heart-rate settings and zone boundaries, training goals, custom workouts, effort ratings, and preferences such as sound, haptics, calendar, and workout appearance. It also maintains workout identifiers and session state needed to manage recording and avoid duplicate or stale sessions.
Local workout cache
ReZone keeps a local copy of imported workout information and derived training results so it can display and update your training efficiently. This cache can include heart-rate samples and workout identifiers. Revoking Health access does not, by itself, erase previously imported information.
Support correspondence
If you contact us, we receive the contact details and information you choose to send. Please avoid sending raw health records or other sensitive information unless necessary for your request. We use support correspondence to respond, troubleshoot, and handle privacy requests.
IPHONE, WATCH, AND LOCK SCREEN
ReZone uses Apple’s device connectivity services to exchange workout plans, settings, session controls, and live workout measurements between your iPhone and paired Apple Watch.
Live Activities and Dynamic Island can display workout details, such as heart rate, elapsed time, and workout status. Depending on your device settings, other people may see this information on your Lock Screen. You can manage Lock Screen visibility and Live Activities through your Apple device settings.
OPTIONAL LOCAL SHARING WITH RESTRAIN
If the shared ReStrain integration is enabled, ReZone and ReStrain exchange limited summaries through a shared container on the device. ReZone can share weekly zone minutes, goals, workout count, VO₂ max, and a summary timestamp. It can receive sleep minutes, recovery score, energy, maximum heart rate, and a timestamp from ReStrain.
This exchange does not include account tokens, identity details, location histories, or raw heart-rate histories. It is a local exchange between the apps, not a developer-server upload. Disabling the integration stops the exchange and removes the shared summaries; it does not delete either app’s independent records or Apple Health records. ReStrain’s handling of information after it receives it is also covered by ReStrain’s privacy policy.
ON-DEVICE COACHING
Where available, ReZone uses Apple’s on-device Foundation Models framework to generate training guidance from your question and a limited training summary. ReZone does not send this prompt or your training information to an external AI provider. When the on-device model is unavailable, the app uses local training rules.
Guidance is advisory. It does not make decisions determining your access to employment, insurance, credit, healthcare, or similar services, and it is not a medical diagnosis.
PERMISSIONS AND YOUR CHOICES
You choose whether to grant Apple Health access and which supported categories ReZone may read or write. You can change these permissions in the Health app or your device’s Health privacy settings. Denying or withdrawing permission can limit features that need the affected information.
You can change training settings, edit or remove saved workouts where supported, disable optional ReStrain sharing, and manage Live Activity visibility. Withdrawing permission does not invalidate earlier processing and does not automatically erase existing local copies or saved Apple Health records.
STORAGE, RETENTION, AND DELETION
App settings, saved plans, effort ratings, and cached workout data are stored locally and retained until changed, removed through available controls, or deleted with the app’s local data.
To remove local ReZone data, use Delete App rather than Offload App on iPhone, and remove ReZone from your Watch if you also want to remove its local data. Shared ReStrain summaries should be cleared by disabling the integration before removing the apps. Shared data can remain available to another installed app that uses the same shared container.
Workouts saved in Apple Health remain there after ReZone is deleted. Manage or delete those records separately in Apple Health. Apple Health synchronization, device backups, restored backups, and any copies made by other apps you authorize are governed by the relevant Apple settings and those apps’ policies. ReZone does not provide a developer-operated cloud health-data storage service.
We cannot remotely retrieve, export, change, or erase health records held only on your devices. If you contact us for support or to exercise privacy rights, we retain the correspondence only as long as necessary to handle the request, resolve related issues, and meet applicable legal obligations.
DISCLOSURES AND APPLE SERVICES
Information is handled by Apple’s operating-system services as needed for permissions, Health storage, paired-device communication, and system features you enable. Other apps can access Apple Health information only in accordance with the permissions you give them. Apple may separately process App Store information or diagnostics under its own policies and your settings; ReZone does not embed a separate analytics service.
We do not send your locally processed health data to advertising networks, data brokers, or external AI services. If we hold support correspondence, it may be handled through the communication service used to answer you or disclosed where legally required. We do not use a privacy request as a reason to ask you for unnecessary health information.
LEGAL BASES AND PRIVACY RIGHTS
Where the GDPR or similar laws apply and we act as a controller, processing necessary to provide the features you request is based on providing the service; optional processing is based on consent where required. Health-data processing relies on your explicit consent where required by applicable law. Permission choices allow you to enable or withdraw the relevant access.
We use support correspondence for our legitimate interest in responding to requests and maintaining the app, or to fulfill a legal obligation when handling applicable privacy rights. We do not rely on legitimate interests to use health information for advertising.
Depending on the law that applies, you may have rights to access, correct, erase, or obtain a portable copy of personal information; restrict or object to processing; and withdraw consent. These rights are subject to applicable conditions. For information held only on your devices, use the relevant ReZone and Apple controls. For information we hold, contact the privacy email above. You may also complain to your local data-protection authority.
The app does not transfer your health information to our servers inside or outside the European Economic Area. Apple’s independent international processing is described in Apple’s privacy policy. If support correspondence requires an international transfer subject to data-protection law, applicable transfer safeguards must be used.
SECURITY
ReZone uses Apple’s application sandbox, HealthKit permission system, and device connectivity mechanisms. Your device passcode, account settings, software updates, and Lock Screen choices also affect the protection of your information. No system can guarantee absolute security.
CHILDREN
ReZone is a general fitness app and is not specifically directed at children. We do not knowingly request children’s personal information through an account or advertising service. Where a child uses the app, any consent required by local law must be provided by a parent or guardian. Contact us if you believe a child has sent us personal information that should be removed.
CHANGES AND CONTACT
We may update this policy to reflect changes to the app or applicable requirements. The updated date identifies the current version. Material changes will be communicated as appropriate, and additional consent will be requested where required.
