We couldn’t find a service as convenient as Google Form. It is not ideal, but it works well. The form is open so that you don’t have to log into Google to answer it, and almost all of the questions are optional, so you can share as little as you please :)

If you do have a phone number to use, you can download one of the clients, register an account and join the group: @OpenStreetMapOrg

I am afraid you must provide a phone number to join Telegram, though Telegram is considered a safe service and is partly built for privacy. You can completely turn of sharing your phone number with Telegram contacts in the Telegram settings.

This is not an official form and will therefore not be shared on all platforms used by OSM users. The weekly graphs will initially not be posted on anything else than Telegram, but the final data will be shared here and will of course include the previously published data, so you won’t miss anything by not joining the Telegram group. :)
