I tried the menu choice to start sharing my data and made a few selections to see how it works. However, after starting to share my data I was not able to find the user interface to make any modifications in the selections I made - or to stop sharing my data altogether.
Do I just have a bad eyesight or does the user interface really disappear after one starts sharing his/her data?
No, it’s not a disappearing UI. Just click on “Edit Location” on the action menu of your dashboard. Then there is a 2nd tab called sharing:
Then:
Ahh… there it is!
I enabled the data sharing using the “main menu” element (in the left panel) and that UI element seems to have disappeared after enabling data sharing. Now I understand that it seemed to be only a shortcut to this Data Sharing Tab.
Thank you for your quick reply!
Looking for that as well. I only see the tabs “General” and “Monitor Settings”, no sharing.
I’m happily sharing data from my outdoor monitor, but I somehow managed to also enable sharing for an indoor monitor - now two devices appear on the public map, and my indoor data is not really useful for other people, so I’d like to withdraw that.
By default, you can only share outdoor monitors. Can you please contact our support with the serial number of your monitor and ask the ticket to get assigned to Nick.
While I understand the historical and business reasons behind such a choice, having anything share user’s personal data without consent as a default is illegal in the EU under the GDPR…
Would be wise to re-think that default before someone in the EU (i promise it won’t be me ;)) ) files in a complaint, as the company would inevitably been fined for this.
Hi @gabu, we appreciate your concern.
We take it seriously when it comes to users’ personal data protection. AirGradient monitors, by default, won’t share their air quality data (your data will never automatically show up on the AirGradient Map, unless you opt in). You need to explicitly enable the public data sharing option to make it public, and you can opt out easily at anytime you would like.
More details about this: Data Ownership & Sharing
Thanks for the clarification, i will look at this into great details.
Note that it is not the sharing to the public that is illegal without explicit consent, but also the sharing with a company.
I see that the airgradient one by default sends its data to the aigradient cloud. If this contains anything personal like an IP address and/or location data, it is already too much.
(i am actually in the process of making sure that when I first connect the device to my wifi network, it doesnt start uploading data to your company without my consent! that’s a journey…)
It seems to me that
{"postDataToAirGradient": true}
is the default in the config?
Just a quick note. When you use the WiFi provisioning to setup your initial connection to your router there is a checkbox “never send data to AirGradient” (or similar). I think this is what you as looking for.
Sorry for the brief reply, I am just traveling with only my phone.
Yes I did that first thing when I associated it. I didnt actually try to intercept traffic to see if anything was transfered at all, as I decided to rather trust you 
Yet after i clicked “never send data…” I noticed that the {"postDataToAirGradient": true} was still present in the config, when polling it through the http interface!
Hi @gabu, let me do some checks with my monitors, and I’ll get back here real quick when I find something.
@gabu I’ve just tested it by connecting my AirGradient ONE to my PC Wi-Fi hotspot (which has an internet feed through the PC’s ethernet port), then capturing packets via Wireshark on the PC Wi-Fi hotspot network.
It’s a relief that in case of “Prevent Connection to AirGradient Server” was checked during the Wi-Fi set up process, I saw no connection from the AirGradient ONE to the AirGradient Server (which is good and expected). So when this is checked, no data is passed to the AirGradient Server, no cloud configuration is fetched to the AirGradient ONE, and no OTA firmware update. Everything is kept local.
This is the configuration when I check via the local API of the ONE:
{
"country": "TH",
"mqttBrokerUrl": "",
"httpDomain": "",
"configurationControl": "both",
"pmStandard": "ugm3",
"temperatureUnit": "c",
"disableCloudConnection": true,
"postDataToAirGradient": true,
"ledBarBrightness": 100,
"displayBrightness": 100,
"ledBarMode": "co2",
"tvocLearningOffset": 12,
"noxLearningOffset": 12,
"abcDays": 8,
"model": "",
"offlineMode": false,
"monitorDisplayCompensatedValues": false,
"extendedPmMeasures": false
}
Even it shows "postDataToAirGradient": true , there’ no data posted to the server (this could create confusion anyway).
Checking the box during the Wi-Fi setup is the only and absolute way to cut off all connections to the internet (or you can optionally block the WAN access of the AirGradient monitor on your Wi-Fi router, so it will be imprisoned in the local area network only and will never see the internet).
If the box is checked and you connect the monitor to your Wi-Fi, you’ll see it shows [16:03:26]Running monitor without connection to AirGradient server on the USB log.
By default (When no check on the “Prevent Connection to AirGradient Server” during the Wi-Fi set up process + "postDataToAirGradient": true + "disableCloudConnection": false ), when the monitor is running, you’ll see it communicates with the AirGradient server (which the IP address is 91.98.9.143)
To conclude that, if you would like to cut off the internet connection, have it worked only on you LAN, the easiest way is to reset your AirGradient monitor by pushing and holding the reset button for 10 seconds, the Wi-Fi setup portal will initialize and let you check the “Prevent Connection to AirGradient Server” box before connecting to your Wi-Fi.
Thanks for that thorough investigation and careful answer!
That great to hear, but it now means that in case “prevent connection…” has been checked, the presence of
"postDataToAirGradient": true,
in the configuration of the device is confusing and misleading… something to be addressed for the sake of clarity only
Good to see that passionate people at Air Gradient take this matter seriously! 
@gabu I’m glad that my findings are helpful for you!
And yes, I agree, the presence of "postDataToAirGradient": true is confusing (even though it is actually overridden by “Prevent Connection to AirGradient Server”).
Let me ask @Samuel_AirGradient (our firmware engineer) if we can improve this.
Thank you so much again @gabu! Let me know if you have any questions or something else to share.
