As an overview, your data will
- Not be shared with third parties
- Won't be used to train AI mode
- Won't be sold to data brokers
- Not be shared with adverters
- Not be shared with insurers


## MVP
Create an android mobile app that can store the weight, blood pressure and how the person is feeling over time. 

I'm not sure how to record how a person is feeling, but it should be simple and concise. Maybe a set of emojies representing overall feelings such as sad, mad, tired, stressed, happy, excited, great, enerjetic etc. The user may be able to select more than one option if that makes sense? e.g. a person could be tired but happy, but probably not tired and enerjectic.

the app should show simple graphs of the data over time.

## Future interations
A future improvement to the app will additionally allow it to trck diet. More details to follow, but the idea would be to help the user identify any types of foods that either make them feel good, or make them feel bad.

## Privacy
By default, no user profile shall be required. The app will only support a single user, so it could not be used to track the data of more than one person. All data would remain on locally on the device.

## Data Store
How should the users data be stored? maybe use sqlite. Could the sqlite data be encrypted and synced remoteley if the user allowed this? this feature would protect the user from data loss, but it should require explicit consent from the user first. If the data is encrypted and the user installs the app on a new device, how will they be able to download, decrypt and restore that data?

could the user be responsible for their own data backup similar to how Obsidian allows you to save the data to a Google drive location for example? 

## monitisation
charge for "pro" features such as the encrypted backup and restore of data. The pro version or subscription would also provide more interactive graphs and insights into the data - but we must respect the privacy first stance before all other features.
