Your sleep data never leaves your phone. Building Bed Debt reads what your watch or ring has already recorded, works out your personal sleep need on the device, and sends none of it anywhere. There is no account and no server.
Made by Winning Beans, based in the United Kingdom.
Nothing. As of 1 October 2026 the app makes no network requests. No analytics, no crash reporting, no advertising, no account.
With your permission Building Bed Debt reads sleep data from Apple Health, which may include data your Garmin device wrote there. We ask for this for one reason: to estimate how much sleep you personally need, and to show you that estimate changing as it learns.
Sleep data is health data and is a special category under UK law. Three commitments about it, all of which we can keep because there is no server:
| Commitment | How it is kept |
|---|---|
| It is never used for advertising | There is no advertising in the app, and Apple forbids it for HealthKit data regardless |
| It is never sold or shared | It never leaves the device, so there is nobody to sell it to |
| You can withdraw permission at any time | iOS Settings → Privacy & Security → Health → Building Bed Debt. The app keeps working on whatever it has already read, and you can delete that by deleting the app. |
We only ever ask to read sleep data. We do not write anything back into Apple Health.
The sleep records it has read, its running estimate of your sleep need, how many recent nights that estimate is based on, and anything you have told it about a particular night.
There is no account, no sign-in and no email address.
Building Bed Debt is not a medical device and does not diagnose anything. Persistent poor sleep has causes an app cannot see — if it is affecting your life, please speak to a doctor.
Where we hold no personal data about you, most of these rights have nothing to act on — but they exist and we will honour them.
You have the right to ask what we hold about you, to have it corrected, to have it deleted, to restrict or object to how it is used, and to receive it in a portable form. To exercise any of them, email support@winningbeans.co.uk. We will reply within one month.
If you are unhappy with our answer you can complain to the Information Commissioner’s Office at ico.org.uk.
Delete the app. Because everything is stored on your device, removing the app removes the data with it. There is no account to close and nothing of yours left on any server of ours, because there is no server of ours.
This app is not directed at children under 13 and we do not knowingly collect anything from them. We could not identify a child if we tried, because we collect nothing that identifies anyone.
If what the app does with data changes, this page changes first and the date at the top moves. We will not quietly widen what is collected and leave this page describing the old behaviour.
