I will, once I've gotten my Time Steel And I of course need to find some time (no pun intended) to work on it. But at least for notifications I've did some more investigations past weekend.


I think I've read some comments from Smokku that at least some kind of investigation happened for MeeRun, or there at least was some interest. As he said these apps require some background app running on the Pebble but it was unclear how to do so.


From what I've read it's, at least for public data, quite safe to use. Take the example of some sports app (reporting scores).
Using the Pebble app (on the phone) you'll have to subscribe to a topic on the service. This subscription is then automatically registered by Pebble (probably based on your Pebble account, the id of the watchapp/service, and the subscribed topics). So no data is send to the service provider. The service provider then sends the pins to Pebble (company/website), but the only data it knows are: its own watchapp/service id, and the topic(s) the pin is associated with. Pebble then combines this data to send the pin to the users who subscribed to these topics. The Pebble app on your phone will then periodically query the Pebble servers to get the latest updated pins.

So while Pebble knows which services and topics you are subscribed to, the service itself won't know anything about you. They just push pins to Pebble, and Pebble does all the work to distribute it to the users who subscribed to those topics. So there will never be any direct communication between your Pebble (or app on phone) and the 3th party service.

There are however ways for Pebble (watch)apps to get some unique token, which they can use to create personal pins. But you of course aren't required to use those.

And besides it's not like the timeline won't work without the external services. But then you will need native apps which push the pins to the Pebble watch (using the phone app). And I don't think that's very likely to happen for Sailfish. Although it might well be possible that some developers will put some effort into it. But there will then maybe be like 10 or 20 native apps which can fill the timeline, while there might be hundreds, or thousands of external services which can fill the timeline.
