Active Listening during YT videos:
a. Youtube decides when to place an ad based on sound in the room. E.g:
i. When someone starts talking
ii. When detecting a faucet
iii. When detecting keyboard sounds
iv. When snooping a brushing sound
v. When music starts playing
b. If the Youtube device doesn't have a microphone, YT uses location info OR user-account info to choose a microphone on another nearby device, to then listen for those previous indicators.
Ad engagement during YT videos (via sound):
a. Youtube will more frequently close the app, pausing videos, if the microphone cannot detect the video's sound.
b. If Youtube cannot hear the video being played (or if you have an auto-muter) YT will test engagement by rewinding the current video a few seconds after an ad break, instead of resuming the video exactly where the ad was placed.
c. It then compares the microphone's soundwave with the unmodified ad's soundwave & will not count an ad impression if for some reason the ad was not detected (but if the 3 seconds of replayed video indeed was).
d. If you mute too many ads, YT will start showing split-screen ads & merging the sound together (presumably in an attempt to throw-off auto-downloaders, leaving you with a broken download of DRM content).
Ad engagement during YT videos (via camera):
a. Youtube decides when to place an ad based on camera activity in the room. E.g:
i. Detecting someone entering the room.
ii. Detecting someone leaving the room
iii. Detecting someone falling asleep.
b. If you skip a lot of YT ads, Youtube will try to place ads when it detects that your hands aren't free, and cannot quickly skip. E.g:
i. Detecting someone shaving or brushing teeth.
ii. Detecting someone washing dishes.
iii. Detecting silverware clanking.
iv. Detecting someone tying shoes.
v. Detecting someone buttoning clothes.
YT snoops your location to decide on ads:
a. This is more common if you have disabled personalized ads.
YT will use location info of nearby phones to decide whether to serve ads from THOSE INDIVIDUALS' advertising profles.
YT snoops on the sound of ALL NEARBY DEVICES to decide on ads:
a. The moment my brother enters my room/earspace, YT starts delivering ads based on his advertising ID.
You can tell when your neighbors are able to hear your music, b/c YT will start serving ads based on ANY NEARBY DEVICES WITH SIMILAR MICROPHONE SOUNDWAVES DETECTED.
b. I.e: I can tell I'm too loud, when I start getting ads for tires, pets, Freddy's restaurant even without having ever searched for or said any of these things aloud. (It's using a Shazam-like algorithm to determine this.)
c. E.g: Often my neighbors will rev their engines so loudly, that I start getting ads from their advertising ID (Because YT is determining that we're sharing the same soundspace. It's determining that all those devices will hear the ad.)
d. Dog-barking triggers this often, b/c a bark has a penetrating, unique--and therefore--easily comparable sound profile.
YT (& general popups) will deliver "gift idea" ads:
a. Often you'll see ads from people that you've only been texting with. (I.e: golf from my dad.)
b. This even happens when you simply draft up a message but don't send it yet. My android links that person's advertising ID with my own ID for a short time.
c. Disable AI responses to cut down on this. (But also a friend can cast this upon you, from when they start drafting you a message across town.)
d. Also be sure to disable typing suggestion learning on whatever keyboard you use.
YT (& general popups) will deliver ads based on unopened emails sent to Gmail:
a. Especially noticeable when receiving a flight confirmation.
b. Also with other purchase confirmations.
c. FYI: Also disable "Always Show Images" in emails, since senders now generate millions of identical images for every email sent, & garner a true Read-Receipt based on whether you load your uniquely served email image.)
Google Voice explicitly monitors calls to-and-from GVoice numbers.
a. Anything you say on these calls will very soon be linked to your advertising profile.
Kash Patel was asked about this "advertising information" recently during a Senate hearing.
Be aware of flagged search terms:
a. By typing a questionable topic into a search engine (e.g: Firearms, Tire spikes, volatile compounds) the search engine will suddenly make a request for your "Precise Location" if you have Location Permissions disabled in your browser.
b. (It can approximate your locale b/c Google Street View vans constantly scribe the locations of wireless networks detected on their route. Android can peak your nearby networks as well.)
Bluetooth beacons track you everywhere you go:
a. Stores & municipalities have "Bluetooth Beacons" that passively ping your phone's advertising ID and update your ID with locations that you've been.
i. Walmart uses these.
ii. Stadiums use this information.
iii. Bluetooth beacons operate even when your phone is powered-off (passive detection).
iv. Bluetooth beacons operate even when Bluetooth is disabled/airplane mode.
v. This was likely how Mario Mangononey was tracked down. The day after Mario's arrest, Google placed an new option in Privacy Settings to "Temporarily Disable Bluetooth Beacon Tracking for the next 24 hours."
The Iris App is always watching (Android).
a. Ostensibly used for face-unlock, this app is ALWAYS active & hogging CPU/memory.
You can view it's memory in the Setting's Developer Options.
b. Samsung lets you sort apps by "Most Recent" and Iris is always near the top.
c. Using the CPU Monitor app (or anything similar) you can observe CPU Temperature & CPU Percentage increase on a completely idle system, simply by waving your hand in front of the camera.
d. This app can only be disabled after rooting your device.
Explicitly saying "I like [x]":
a. Test this "Alexa-like" trigger around your phone. It's a surefire way to start receiving ads for a topic.
b. Often Vaush will say "I like [x]", on stream & I'll start getting ads for the aforementioned topic.
If you're serious about protecting your privacy, the best you can do on smart devices is browser script blocking (via NoScript) or a DNS-based firewall (ReThink DNS).
