How Dosette uses Apple Health without uploading your data

The short version

• Apple Health access is optional.
• You choose which supported categories Dosette may read.
• Dosette asks for read access, not permission to write to your health record.
• Selected readings are processed and stored on your device.
• They are not uploaded to a Dosette server or used for advertising.
• You can review or revoke access in the Health app.

Why connect Apple Health at all?

Dosette lets you compare supplement routines with outcomes you care about. You can rate subjective indicators such as energy, focus or sleep quality yourself. Apple Health can add measurements that are already being recorded by your iPhone, Apple Watch or another connected source.

The supported categories are sleep duration, resting heart rate, heart rate variability, steps, active energy, weight, blood oxygen and respiratory rate. You can select only the ones that are useful to you.

These numbers add context, but they do not prove that a supplement caused a change. Dosette still treats the result as a pattern in one person's records and keeps its confidence deliberately limited. The Dosette methodology explains that distinction in more detail.

Read-only means read-only

Dosette requests permission to read the categories you select. It does not request write access and cannot add, edit or delete measurements in Apple Health.

This matters because the Health app may combine information from several sources. Dosette uses the readings available to it for your private comparison, but it does not become another source writing values back into your health record.

Where the readings go

Apple Health readings used by Dosette are handled on your iPhone. Like your supplement list, medicine schedule, dose history and daily check-ins, they are stored locally for the app to use. There is no Dosette account and no health-data server receiving a copy.

If you export a backup, the app creates a file for you to save or share through a service you choose. At that point the exported file is under your control and is subject to the storage or sharing provider you select.

What “Data Not Collected” means

The Dosette App Store listing currently shows “Data Not Collected”. Apple defines collection for its privacy label as transmitting data off the device in a way that lets the developer or a third party access it beyond the time needed to service a request. Dosette does not transmit your supplement records or selected Apple Health readings to Dosette servers.

The label is a developer-provided summary, not a substitute for checking the full privacy policy and the permissions an app requests. Apple’s App privacy details guide explains what developers must disclose and notes that developers are responsible for keeping those answers accurate.

A five-minute privacy check for any supplement tracker

Before putting a health routine into an app, check the product rather than relying on a broad “privacy-first” promise:

1. Read the App Privacy section. Look for data linked to you, data used to track you and the purposes the developer lists.
2. Open the full privacy policy. Check whether health entries, identifiers, analytics or crash reports leave the device, and which third parties receive them.
3. Inspect Apple Health permissions. A tracker should explain each category it wants. Decide whether it needs read access, write access or both for the job you expect it to do.
4. Check account and sync requirements. An account or cloud backup can be useful, but it changes where your records exist and who may be able to access them.
5. Plan for export and deletion. Know how to move your records, what deleting the app removes, and where any exported backup will be stored.

For Dosette, the answers are: no account, optional read-only Apple Health access, local storage for core records and a backup file that leaves the app only when you choose where to save or share it.

You remain in control of access

Apple lets you review Health-compatible apps and turn individual health categories on or off. On iPhone, open Health, tap your profile picture, then under Privacy tap Apps and choose Dosette. Apple's current instructions are available in Manage Health data on your iPhone.

If a category is turned off, Dosette cannot read it. You can also use Dosette without connecting Apple Health and record manual indicators instead.

Why “no data yet” can be ambiguous

iOS protects the privacy of read permissions. An app cannot reliably distinguish between a category you declined to share and a category that simply has no readings. That is why Dosette does not claim to know that permission was granted. If nothing is returned, it says there is no data yet.

This may feel less specific, but it avoids turning the permission system itself into a clue about private health information.

What Dosette does not do

Dosette does not use Apple Health data to diagnose a condition, recommend a dose or advise you to start, stop or change a medicine. Apple Health measurements can support a personal comparison, but they are not automatically more meaningful than how you actually feel.
