My (Social) Data Space

My (Social) Data Space is a private journal for the things you measure — coffee brews, workouts, meals, plants, readings. It keeps everything on your phone and shares an entry only when you choose.

WRITE IT DOWN YOUR WAY

Type your usual notes, like "18 g in, 40 g out in 27 s", and the app fills in the fields for you, even offline. Make a topic for what you track and choose its fields once; every entry after that has the same shape, so numbers stay numbers. Add a photo if you like, then tap it or tap View data to see the numbers behind it.

LOOK BACK AND COMPARE

The data library searches, filters and sorts every entry and shows them as cards, a table or a timeline. Data helpers turn saved readings into a number, a trend or an alert. Bring in older records from a spreadsheet file, or read values from a screenshot on the phone instead of typing them again.

YOUR DATA STAYS ON YOUR PHONE

There is no account on a server. Your private account is a key created on this phone, with no email and no password. Nothing is uploaded in the background. There are no ads, no analytics and no advertising identifier, and everything works offline.

YOU CHOOSE WHO SEES EACH ENTRY

Every entry is Only me or Public. Only me stays on this phone. Public goes to the people you picked, in one of two ways:

• Nearby: straight to another phone on the same Wi-Fi, over an encrypted connection.

• Community: a group runs its own small service. Join with an invitation link or QR code from its organiser. The app shows you the service first and connects only when you tap Use this service.

The app comes with no community built in. Until you join one, your Feed shows your own entries and what people nearby share with you.

THINGS YOU CAN DO

• Record structured entries and follow them as trends

• Try an example post before you create anything

• Send private messages and share entries with a person nearby

• Join topics, reply and compare with a community you joined

• Set alerts for readings where finding out late matters

• Answer a data request from someone in your community who needs a measurement you have

• Confirm exports and deletions with your fingerprint, face or PIN

• Save a readable copy of your entries, topics and the messages you wrote, and restore it on a new phone

• Delete your account and erase this phone's data completely

WHAT THIS APP DOES NOT DO

It does not diagnose, treat or give medical advice. It is not a substitute for a device or an alarm you rely on for safety. It does not sell your data, because it never collects it centrally in the first place.

ABOUT THE DATA YOU SHARE

If you join a community, photos and videos inside what you publish are stored where anyone holding the link can fetch them. Deleting your account erases everything on this phone, and cannot reach copies other people or that service already hold. The About screen inside the app says all of this too.
