Hello Tella Community!

We're thrilled to share that Tella Android 2.10.0 is now live 🚀!

Introducing Privacy-Preserving Analytics (opt-in)

One of the features included this release is our new privacy-preserving analytics system. Users now can choose to share anonymous usage data to help us improve Tella. We understand how important privacy is to our users, so we chose Divvi Up, a privacy-respecting telemetry service by the Internet Security Research Group (ISRG), the nonprofit organization behind Let's Encrypt. We were the first implementer of Divvi Up in Shira (another of our products) and we are very happy with how it is working, so now we added it also to Tella.

Here are some key details about the implementation:

  • All data is anonymous and aggregated: the Divvi Up library splits the data into two anonymized and encrypted shares and uploads each share to different data share processors (one hosted by ISRG and one hosted by us) that do not share data with each other. This way, only partial information about the original data is revealed to either processor.
  • Even if we wanted to, we wouldn't be able to get the whole data: It's not possible to construct the whole data with only one share. Each processor aggregates its data shares into a partial sum. The partial sums can then be combined into a final aggregation, permitting useful statistics over the whole body of data while revealing minimal information about individual participants. Extensive technical documentation about how Divvi Up works can be found here.
  • We collect as little data as possible: Even though all data is anonymized, we always minimize the amount of data we collect. All metrics collected are listed here.

In addition to our new analytics system, Tella 2.10.0 also includes:

Uwazi Relationships property support: We’ve added support for the relationship property type in the Uwazi connection.

Vietnamese language support: Vietnamese language support has been added, along with updates to existing translations, like always, thanks volunteers coordinated by our friends Lokalization Lab (and you can contribute too!).

Bug fixes and UI improvements: We’ve addressed various bugs and made small improvements across the app. Notable fixes include resolving issues with the "Contact Us" button, improving the functionality of the "Cancel" buttons, and fixing crashes related to audio recording and ODK geolocation.

As always, we’d love to hear your feedback, so please don’t hesitate to reach out with any comments or suggestions.

Thank you for being a part of the Tella community!
