Hi JP.
First off: Thank you for everything you do for/within the TTN-community. Open projects live from user contribution. TTNMapper has always been a valuable tool for me and it would be very sad if the service would go down.
Regarding the latent data privacy issues: aren’t those persons mostly lora mapping drivers? I think they wanted their tracks/data to be public. One way to mitigate this might be to truncate the data, to e.g. 5 or 3 years of retention. You already offered data removal to anybody in the FAQs. I’m interested: did anybody ever complain you did not remove their data when they actually requested it?
Cheers from Germany
