The short version: Mind Frame reads data from Apple Health on your device. That data never leaves your device. Mind Frame has no server, no account system, and no way to see anything about you. Everything stays on your phone.
1. Who makes Mind Frame
Mind Frame is made by Delaybox Ltd, a company registered in England and Wales.
If you have any questions about your privacy, email us at: privacy@delaybox.com
2. What Mind Frame does
Mind Frame reads your Apple Health data — specifically your State of Mind entries — and shows you how they relate to other signals like sleep, steps, heart rate, and daylight. The aim is to help you notice patterns you might not otherwise see.
All of this happens on your phone. Mind Frame does not use a server. It does not send your data anywhere. It does not know who you are.
3. What data Mind Frame reads
Your Apple Health data
Mind Frame asks for permission to read certain types of data from Apple Health. It only reads what you specifically allow through the standard Apple Health permission screen.
The types of data it may read, if you have it and allow access, are:
- Activity — steps, active calories, exercise time, stand time, move time, wheelchair distance and push count
- Sleep — sleep duration and analysis
- Heart and breathing — resting heart rate, heart rate variability, respiratory rate, blood oxygen
- Daylight — time spent in daylight
- State of mind and mindfulness — your State of Mind entries (requires iOS 18 or later) and mindful session time
- Cycle tracking — menstrual flow, ovulation tests, and related data
- Medications — dose records and medication types, if you use medication logging in Apple Health (iOS 26 or later only)
You are in control of all of this. You can allow access to some categories and not others. You can change your mind at any time in: iPhone Settings > Privacy and Security > Health > Mind Frame.
Mind Frame is read-only. It can never add to, change, or delete anything in your Apple Health data.
A temporary local copy on your device (on-device cache)
To avoid repeatedly asking Apple Health for the same data, Mind Frame stores a short-lived local copy — called a cache — in a private folder on your phone. This is standard practice in iOS apps to avoid unnecessary battery and processing drain.
- The cache exists only on your device, stored in a sandboxed app container that iOS strictly isolates from all other apps.
- Delaybox cannot access this cache. Nobody can — not us, not Apple, not any other app. Only the locally running instance of Mind Frame on your phone can read it.
- It contains the same data already present in Apple Health — nothing additional is created or inferred and stored here.
- It refreshes automatically every 6 hours, at which point any stale data is replaced.
- It is permanently and irreversibly deleted when you delete Mind Frame from your phone.
- Mind Frame does not instruct iOS to back this folder up to iCloud. It stays local.
Your in-app settings
Mind Frame remembers your preferences — such as which health categories you've turned on and which display options you've chosen. These are stored on your device using iOS standard storage. They never leave your phone.
4. What Mind Frame does not do
This is not a general list of reassurances — it reflects how the app is actually built:
- Mind Frame makes no connection to the internet. It contains no code that sends or receives data from any server.
- Mind Frame does not know who you are. There is no account, no login, no name, no email address.
- Mind Frame does not track how you use it. There is no usage analytics, no behavioural logging, no session recording.
- Mind Frame does not send crash reports to us or anyone else.
- Mind Frame does not use any third-party software components that could access your data. It is built entirely using Apple's own frameworks.
- Mind Frame does not access your location, camera, microphone, contacts or calendar.
- Mind Frame does not sync anything to iCloud.
5. Health data and the law
Health data — including information about your physical health, mental wellbeing, cycle, and medications — is given special protection under UK data protection law. It's treated more carefully than ordinary personal data.
Because Mind Frame never transmits your health data off your device, Delaybox never receives or processes it. The analysis runs entirely on your phone, using Apple's Health framework.
If you'd prefer to limit which types of health data Mind Frame can see — cycle tracking or medication data, for example — you can do that by category in: iPhone Settings > Privacy and Security > Health > Mind Frame. Turning off one category does not affect the others.
6. Payments and subscriptions
The Relationships and Patterns features in Mind Frame require a subscription. Subscriptions are purchased and managed through Apple's own billing system. Delaybox never sees your payment details.
To manage or cancel your subscription: iPhone Settings > Your Name > Subscriptions.
If you've previously subscribed and need to restore access, you can do this from within the app.
7. Trying the app before connecting your health data
Mind Frame includes a demo mode with five sample profiles. These use entirely made-up data — none of it comes from Apple Health or from you. Demo mode is there so you can explore the app before deciding whether to connect your real data.
8. Your rights
Under UK data protection law, you have certain rights over personal data held about you. Because Mind Frame holds none of your data on our systems, most of these rights apply to Apple — as the keeper of your Health data — rather than to Delaybox.
Apple's privacy policy and data request process can be found at apple.com/uk/privacy.
If you've contacted Delaybox directly — for support, for example — and want to know what we hold about you, or want to correct or delete it, email us at: privacy@delaybox.com
You can also complain to the Information Commissioner's Office at ico.org.uk if you feel your data hasn't been handled properly.
9. Security
Because your data never leaves your device, the most important security measures are the ones already built into your iPhone — your passcode, Face ID, and keeping iOS up to date. We recommend keeping these active.
The temporary copy Mind Frame stores on your device is kept in a private app folder that other apps cannot access.
10. Children
Mind Frame requires Apple Health, which Apple limits to users aged 13 and over. We do not target children specifically, and we do not collect personal data from any user regardless of age — there is no account, no registration, and no data sent to us. The app's age floor is effectively set by Apple, not by us.
11. If we change how Mind Frame works
If a future version of Mind Frame introduces anything new that affects your privacy — for example, optional cloud backup, an account system, or analytics — we will update this policy and publish the new version before that update is released. We will not make changes that affect your privacy without telling you first.
