Oso

This is : a light, anonymous ,amnesic, personal, safety tracking.

The aim is to have an app which :

• is battery restpectfull: the less power it need the better.
• is loginless: I do not like to have to create an account on every service I use. So this one in design to be donwload and play!
• is anynonymous: when you enable the tracking , the server give you a random ID, which will change on your new track.
• is amnesic: The tracks will be remove from the server after X (need to be define) days.
• is personal : you share the "follow me" link to the person you want.
• is privacy respectfull: No private or usage data are store or send. Just the trackpoints ( can be redirect to your own server)
• no ads no analytics stuff : light , simple and privacy respectfull we said !

What Oso is not:

• a maps apps. No maps display, there are thousand of apps which do that very well ( c.f Osmand).
• a stealth tracker.

Description :

It is composed by 3 parts:
