The short version

What Health Connect does

Health Connect is Android's system for sharing health and fitness data between apps with your permission. For example, a watch or fitness app can add a step count, and another app can read that total after you approve access. Google explains that Health Connect stores this data on your Android device and lets you control which apps can access each type in its Health Connect overview.

Health Connect is built into Android 14 and later. On Android 13 and earlier, it is a separate app available through Google Play. Dosette works with Health Connect rather than asking every wearable or fitness service for a separate connection.

What Dosette reads

Dosette can read eight supported daily indicators: sleep duration, resting heart rate, heart rate variability, steps, active energy, weight, blood oxygen and respiratory rate. Nothing is connected automatically. You select an indicator in Dosette and Android shows the relevant permission request.

The purpose is to place measurements you already collect beside your supplement history. That can reduce manual entry and make it easier to compare longer periods. It does not prove that a supplement caused a change. Wearables, routines, illness, travel and many other factors can affect the same measurements.

For steps, active energy, resting heart rate and weight, Dosette uses Health Connect's daily aggregate where available. This matters when more than one source records the same activity. Health Connect can combine compatible sources according to the priorities you set instead of Dosette blindly adding overlapping records.

What Dosette does not write

Dosette does not write data to Health Connect. Your supplements, prescribed medicines, dose history, reminders, wellbeing check-ins and experiment plans remain Dosette records on your device. They do not become entries that other Health Connect apps can read.

Read-only access also means Dosette cannot edit or delete the measurements created by your watch, phone or another connected app.

Why it may ask for history access

By default, Health Connect limits a newly connected app to roughly 30 days of earlier data. Android offers a separate permission for older history. Its developer documentation explains both the default limit and the additional history permission.

Dosette asks for history access because its evidence view compares longer stretches of time. A few recent days may be enough to populate today's indicators, but not enough to compare meaningful on and off periods. If you do not grant history access, Dosette stays inside the normal recent-data window rather than treating missing older readings as zero.

Where your readings go

When you connect an indicator, Dosette reads the permitted values and stores the resulting daily readings in its local database on your phone. There is no Dosette account and no cloud sync for these core records.

Dosette's optional AI features are separate and user initiated. If you ask for an AI insight, only the data needed for that request is sent to answer it, and it is not stored by Dosette. Simply connecting Health Connect or using the core evidence view does not send your Health Connect readings to a Dosette server.

If you create a Dosette backup, the app gives you a file to save or share through a location you choose. That exported copy is then subject to the storage provider and sharing choices you make.

How to review or revoke access

Open Health Connect, choose App permissions, then select Dosette. You can turn individual data types off or remove all access. Google's current steps are in Manage connected apps in Health Connect.

Removing a permission stops future reads. It does not automatically remove readings already copied into Dosette, just as removing another app's access does not delete copies that app already made. To remove Dosette's local copy, delete the relevant indicator data in Dosette or delete the app and its local data.

What if Health Connect shows no data?

First check that another app or device is actually writing that data type to Health Connect. Then confirm that Dosette has read permission for the same type. If you are looking for records older than the recent-data window, check whether history access was granted.

A missing day is treated as missing, not zero. No step record might mean your watch was charging or a source did not sync. It should not be turned into a claim that you took zero steps.

Common questions

Does Dosette write supplement or medicine data to Health Connect?

No. Dosette uses read access for the health indicators you select. It does not write your supplement list, medicines, doses, check-ins or other records to Health Connect.

Which Health Connect data can Dosette read?

Dosette supports sleep duration, resting heart rate, heart rate variability, steps, active energy, weight, blood oxygen and respiratory rate. You choose which supported indicators to connect.

Why does Dosette ask to read older Health Connect data?

Health Connect normally limits a newly connected app to recent history. Dosette can ask for separate history access because comparing longer stretches is more useful than seeing only a few recent days. You can decline it, but older comparisons may then be unavailable.

Can I use Dosette without Health Connect?

Yes. Health Connect is optional. You can track doses and use manual indicators such as energy, sleep quality, focus or pain without connecting it.

Limits of personal health data

Health Connect can make a record more complete, but it does not turn a personal comparison into a clinical trial. Dosette reports patterns in your own data and deliberately limits its confidence. It does not diagnose, recommend a dose, or advise you to start, stop or change a medicine.

Private supplement tracking on Android

Dosette is free to download on Android. Track supplements and medicines, choose the outcomes that matter to you, and optionally bring in selected Health Connect indicators.
