Do_not_track

 https://donottrack.sh/

by RubyGuy

5/3/2026 at 2:29:47 PM

My projects could genuinely benefit from telemetry as I have no idea about usage patterns and my community (mainly artists) is not famous for maintaining a close dialogue with software developers.

I haven't bothered because a) opt-out risks a backlash and b) opt-in affects the data so much it becomes useless (much smaller sample and probably self-selecting a certain type of user)

Skimming the comments here, it seems everybody assumes telemetry is always nefarious. I get the distrust of large corporations and other obvious bad actors - but the blanket cynicism for all telemetry here is kinda surprising. Have none of the developers here ever had a need for it themselves?

by andybak

I’m sympathetic to both the default distrust and to devs like you who want telemetry to improve their software and won’t use the data for anything else, but it is because of bad actors and enough dark ad patterns that we just can’t trust companies to play nice, and it’s too difficult to expect people to scrutinize each and every app or site individually. So I get why the default assumption is nefarious behavior.

But you’re totally right - telemetry & crash dumps & analytics are helpful & great for devs who care about the customer UX and don’t use the data for advertising or anything other than fixing & writing good software, so it’s a real kind of tragedy of the commons that we can’t have safe, trustworthy, and pro-consumer telemetry.

I went from building a web app that used Google Analytics and some other kinds of anonymous telemetry (and using that data only for identifying functional software & site issues), to building driver software that absolutely cannot send data out, and I wish for telemetry all the time. Not only is it difficult to understand what users are doing, they usually don’t even know themselves and can’t tell me what happened when things crash. The result is that turnaround times for critical issues are in months, when it could be days or hours if we had crash dumps and analytics, the lack of automated reporting hurts users.

I’m not sure there’s a way to separate the good from the bad, to designate some kinds of telemetry as safe and to be able to trust it while disallowing the stuff we don’t want. If that were somehow possible, if anyone has ideas, I would love to help figure out how to make it a reality.

Opt-in data is "useless"

That's one I have not heard before

Useless for what

Targeting a certain "type of user" perhaps

"I get the distrust of large corporations and other obvious bad actors - but the blanket cycnicism for all telemetry here is kind surprising"

There is effectively no way for a user to determine whether an actor is "bad" or "good" and that definition may vary depending on the user

The user cannot verify how the data might be used or where it might be transferred. As such, there is almost zero incentive for the data collector not to engage in malfeasance (as the user defines that term); deterrents are lacking

Perhaps there is irony in criticising "blanket" cynicism whilst arguing for "default" telemetry. Both suffer from the same "one size fits all" error

by 1vuio0pswjnm7

5/4/2026 at 4:07:03 AM

Begs the question: Why isn't opt-out "useless"

Perhaps because only way to get large sample size is to target users who are unaware of "defaults", i.e., remove choice

Perhaps when forced to make a choice ("opt-in"), users will not choose to share data (unless the developer uses dark patterns to manipulate the choice)

Why is that

Who's providing the telemetry/analytics if not one of same large corporations?

Many devs say they care about user privacy, but very few seem to care enough not to farm surveillance out to a 3rd-party they have no control over.

by deanishe

5/4/2026 at 5:55:53 AM

> Who's providing the telemetry/analytics if not one of same large corporations?

Erm. It would be me? The idea was that the app (not a web app btw) would send back data about which features were being used (to a server I control) so I could build up a picture of how often various features were being used relative to other features. Nothing remotely personally identifiable.

by andybak

5/3/2026 at 6:01:35 PM

Telemetry only tells you what users do, not why and doesn't explain their mental models. Try asking directly: open a discussion board (for example Github's Discussions) and encourage them to post about aspects of the software they found puzzling/annoying/inefficient. Take 15 minutes a week to go through the posts to see if anything attracts your attention.

by ragall

5/4/2026 at 7:04:09 AM

Normal users don't register on a discussion board to tell about what went well during a normal day.

People only bother when something has made them really angry about something and need to vent.

This is why default analytics is the correct option. It gets the average people who don't care about forums and usually won't even bother to change many of the settings. The crowd who doesn't open HN first thing in the morning.

It's interesting that we're so used to be tracked at this point that no one balks at being opted-in by default. A flag called DO_NOT_TRACK sounds like a good idea, but also suggests the default is CONSENT_TO_TRACK=1, and I find that creepy.

I actually consider such a flag to be problematic. I don't want to give out any information - of course I never want to be tracked, but marking this via an ENV variable alone, already makes zero sense to me. I don't understand people who like that while claiming they do not want to be tracked; if they give that information, then this means they are marked.

Nitpicking: There is no being opted-in by default, that‘s opt-out

by croes

5/3/2026 at 5:56:42 PM

Hmm. I read a semantic difference between "opt-out" and "being opted-in by default".

The first denotes an abstract policy, the second an action that has been done to you in which you were a passive participant. And this is all about our lack of agency.

You may prefer that we speak of abstract policies. But to say "there is no" about an otherwise sensible phrase implies that you think that we have agreed to stay within some fixed set of terminology. I didn't think that we had.

by marshray

5/3/2026 at 6:14:19 PM

If you hadn’t the option to go in it is not opt-in.

If so put you in by default but you have the option to go out it’s opt-put

So this is either opt-out or not a option at all

by croes

5/3/2026 at 6:59:29 PM

The law of the excluded middle does not create semantic problems for the phrase "being opted-in by default".

Human language does not work like that.

by marshray

5/3/2026 at 11:05:10 PM

There is no excluded middle.

You have to turn it on = Opt-In

You have to turn it off = Opt-Out

Just because the option was added later on doesn’t change that.

Or tell me what’s the difference for me between Opted-In by default and Opt-Out

Do not track WHEN?

This flag is sent by my browser when I connect to SOMEONE ELSE’s SERVER.

The internet only took off because the primary business model which ran on ads and derivative information that servers do to their users.

It’s not fun. It’s not private or secure. It’s not illegal (in most jurisdictions for most industries). The flag exists as a response to the de facto and de jure state of the world, not some fairytale scenario.

No? It took off before advertising was widespread as a primary or sole funding business model? Also there's literally nothing about advertising that requires data collection about users. Sure they love to do it, and they might even believe that it helps their profits in some way. But it's not inherent, they got along just fine with billboards and newspaper classifieds. TV ads never required personal information. Not did pre roll cinema ads, or radio adverts. Nobody was bemoaning in the streets that they couldn't possibly find anything to buy

No, it's set in your command shell (e.g. bash) and tells CLI programs that support it to not connect to a server. It has nothing to do with browsers or ads. This is all very clear in the article.

I always choose to go with positive terms with variables etc, so this would then be ALLOW_TRACKING=0. It brings in some consistence and makes it easier to reason, as you get to avoid double negation.

Perhaps the "DO NOT TRACK" name is somewhat of an established term, though.

by _flux

One could also implement ALLOW_TRACKING as comma separated list for applications I choose to allow it. Say I would like to share telemetry with go and brew, but not aws and the rest ALLOW_TRACKING=go,brew

There's an inherent conflict. No one _wants_ to be tracked, there is no direct benefit to being tracked and only downsides. And advertisers want to track you. So there was no way to respect the flag other than making it obscure so only a few dedicated people turned it on.

To play devils advocate there is a direct benefit to being tracked, at least theoretically search and ads will more relevant to you. I get no one wants ads but you do see ads here and there. It would arguably be better for you if everyone of them was relevant than not. Similarly search or even LLM answers could be better if the preferences of the asker are known

No, in not making excuses for tracking and I do lots of stuff myself of avoid being tracked

I’m only responding to the false premise that there are no benefits. There are. You can just choose to believe they aren’t worth the cost. I believe they aren’t but I have friends who opt into all tracking and even register their presence with multiple apps. They believe they’ll make more positive connections

by socalgal2

5/3/2026 at 6:49:40 AM

> theoretically > they believe

Exactly. From my experience: the times I've found an ad relevant and worth clicking is about one-to-a-gazillion. Maybe relevance is higher for others but that still doesn't necessarily translate to real value. (ie. your life was improved in any way)

Also, this all presumes the targeting actually works and the current sea ads for shoes I just bought disagree with that. It's all just spam.

Microsoft is too sophisticated to plead ignorance; they are responsible for that outcome and I think we can assume they knowningly chose it. (Though now Microsoft browsers are such a small portion of the market that it doesn't matter.)

The biggest failure of DNT was browser makers - including Mozilla - removing it. It has zero performance impact (1 bit?) or development cost. As long as it was out there, when there was momentum against tracking, advocates had evidence of both demand for privacy and of trackers ignoring user wishes.

by mmooss

5/3/2026 at 12:40:17 AM

> advocates had evidence of both demand for privacy and of trackers ignoring user wishes.

This evidence both still exists and is also completely useless for anything. The more important consideration, by far, is that the DNT flag was actively harmful to users in the real world because, if it was acknowledged at all, it was used maliciously to help fingerprint and track users. There is no reason for browsers to continue providing to their users a toggle that not only misleads them about what will happen with the setting enabled, but actively contributes to the opposite outcome because we live in a world where being evil is the norm.

by dylan604

5/3/2026 at 8:23:52 PM

Advertisers ignored it because MS decided to turn it into opt-in instead of opt-out, and advertisers very much hate opt-in. They'd much rather require the most permissive defaults, and put every barrier they can in front of opting out.

by LocalH

5/4/2026 at 12:14:02 AM

Users usually don't know about or change settings, so opt-out often means little. What portion of users knows about DNT? 1% 0.1%

Microsoft knows that; they rendered DNT meaningless:

I was surprised how hard it was to stop the Python transformers library from phoning home to Hugging Face. I set HF_HUB_DISABLE_TELEMETRY=1, and when I called Wav2Vec2CTCTokenizer.from_pretrained I explicitly passed local_files_only=True, but still I got got a warning about not having a valid HF_TOKEN. It wasn't until I stumbled upon HF_HUB_OFFLINE=1 that I'm somewhat confident that I'm not making outgoing connections to HF every time I load a wav2vec2 model from disk.

I wouldn't have realized this was happening at all if it weren't for the obnoxious HF_TOKEN warning.

by spudlyo

5/2/2026 at 8:51:41 PM

HF is notorious for making it difficult to work offline (or at least not waste time trying to connect when everything needed is offline) and is constantly changing how it is being handled. Previously, there was TRANSFORMERS_OFFLINE, HF_DATASETS_OFFLINE, etc.

Looks like a helpful honeypot! Any tool that will public announce support for this spec is a tool I know to avoid because it collects telemetry without explicit opt-in in the first place.

by ximm

5/2/2026 at 8:57:45 PM

DO_NOT_TRACK support doesn't mean tracking is not an explicit opt-in.

Example: the software crashes, and there is a crash handler that asks you if you want to send a crash dump. With DO_NOT_TRACK, the crash handler is disabled entirely, no question, no dump.

If it gets some adoption, that's probably how it will work. Those who have an financial interest in using tracking (ex: ads) probably won't support such an option.

Not the person you are replying to, but I had the same thought come to mind. Every library and app seems to have its own way of disabling telemetry.

Otherwise you now have DO_NOT_TRACK=1 for everyone who respects it in addition to all of the existing ways for everyone who does not respect it.

I was worried about .NET sending telemetry once I found about the existence of the DOTNET_CLI_TELEMETRY_OPTOUT env.

Thankfully, the dotnet package installed by package manager on Arch Linux disables telemetry by default. I left the env set just in case.

But my trust towards "modern" software has lowered. I default to run CLI tools, especially those built in JavaScript or .NET with network disabled:

    firejail --net=none
For ilspycmd, for example, I had to defuse its default "update checking" behavior:

    alias ilspycmd='ilspycmd --disable-updatecheck'
This is what I'd call user-hostile defaults.

by Grom_PE

This proposal is really harmed by the name.

There is a reason none the existing methods use the word "TRACK". Although connecting home can be used for tracking it doesn't have to be.

If a tool uses connecting home for telemetry, implementing "DO_NOT_TRACK" would suggest it does track its users without the setting, even if it may not.

Rename it this to "DO_NOT_CONNECT_HOME" and it may be a useful standard.

The only way to force companies to stop mass tracking without consent is to flood them with fake tracking data. If enough people install noise generators for all opt-out trackers, opt-in becomes the only viable model.

Many of these tools are source available or supposedly open source, so it can't be that hard to take their tracking endpoints and call them in random order.

by jeroenhd

5/3/2026 at 12:54:59 PM

If any org had any use for telemetry they'd have no incentive into to adhere to something that would make it easier for users to opt-out. In fact that thee whole reason you have to opt-out instead of opt-in in the first place.

Its an ok solution, but will never be implement and doing it actively goes against the interest of those who would have to do implement it.

I doubt any vendor would apply this. It's not in their interest. Maybe a better solution would be to have a package that's always updated and provides a list of injected env vars for each vendor. One line in zshrc or bash and you're covered (at least for those who offer a way to disable the telemetry through an env var).

I applied it to PhotoStructure more than a year ago—I think it was when I first saw this on HN?

My point is that there *is* such a thing as software that tries to respect their users. I'm not the only one.

I don't think there is any way to stop people from tracking you. Technically speaking, you can pretty much always be tracked. Even if you eliminated all third party requests you could still be tracked. Downloads, logins, queries, etc all can be tracked. Virtually all software now has the "continuously upgrade to the latest version" bullshit so you are tracked every time you open the app. Even if you turn it off, they stop the app from working until you upgrade, so they force you to be tracked.

I think the only solution is to make it law that you can't track anyone for any reason without their consent, and can't sell consensual tracking data without an additional consent agreement. It would be a huge blow to the advertising industry, so it will never be made law, but it's the only thing that would work.

Also every time you install a program Microsoft, Apple and Google knows depending on the device. For your safety of course. The tracking is so pervasive and the majority of people do not care.

It’s already a law in Europe. GDPR and ePrivacy. You have to get consent from the user. Having worked for European companies, they take it seriously.

A GLOBAL do not track on the browsers works largely cause the target is all the websites being browsed and the tracking associated with it for advertising purposes. However telemetry is altogether a different thing, blocking it by default can be one idea, however using one standard variable to express the intent for all the tools is not practically viable

The issue is that it is not enforced. My version of My IP will tell you if 'Do Not track' and 'Global Privacy Control' are set by your browser but it is up to the website to honour your requests. Check if your browser is sending them by visiting: https://fshot.org/utils/myip.php

This is just sad. Luckily I do not use any of the listed programs. I threw out Homebrew many years ago when they started this nonsense.

The only tool I have installed currently that does %/"($& like this is Deno (required for yt-dlp now). It phones happily home even if you wrap it into a wrapper script that forces the env variable (in no way I'll pollute my default environment with stuff like this):

    $ cat /usr/local/bin/deno
    #!/bin/sh
    exec env DENO_NO_UPDATE_CHECK=1 /usr/local/packages/deno/latest/bin/deno "$@"
I wish bad dreams to whoever puts such crap into their software! Thankfully I have Little Snitch to catch most of those kind of invasions of my privacy.

No, it should be a required (by law) opt-in TRACK_ME_I_DO_NOT_CARE_OR_AM_A_TEAPOT=418.

The proposed way just normalizes tracking.

by buybackoff

5/2/2026 at 11:55:33 PM

And setting that env var should require a notarized consent to track contract that has an expiration of at most 60 days and has penalties of jail time for any data related to that telemetry, anonymized or not that is shared with a third party, for any reason, including but not limited to fulfilling the service the business purports to be providing.

It should be much more difficult to collect data than to opt out of collection.

by jonhohle

Domain blocking is my preference but I would imagine that trackers probably also try to weed out data that contains racism, sexism, lewdness or some combination thereof. People can get very creative with ASCII art. AI surely does not accept such things.

The reason browser's DNT header failed is that they don't want to user to turn off tracking by default

The reason they will not adopt common env is that because they do not want it to be easy to turn off

by PunchyHamster

5/3/2026 at 9:37:18 AM

The reason the DNT header failed is because there is no way to enforce it. The browser can set the flag, but there's no way to ensure it's actually respected. There are no protocol police.

You can also use network namespaces to simply block internet access for certain processes. It can even be finetuned with whitelists or blacklists.

by amelius

5/2/2026 at 9:06:10 PM

Could you provide more details? Many applications use multiple processes, and use some intermittently. It seems like quite a bit of work to enumerate every process used and then to keep the white/blacklist updated as usage and software changes - every new application or command you use, every update, every OS change that affects networking or system calls etc ...

by mmooss

5/2/2026 at 9:42:46 PM

Yes, with security comes inconvenience, this is inevitable.

I'm not a daily user of network namespaces, and would probably write a script to do the configuration within a shell (it works a bit like containers). The configuration is inherited by child processes, so you only have to do it once. Basically whitelist the urls you typically use, and maybe let the script popup a dialog asking you to allow access when the firewall catches a domain that is not in the whitelist yet.

I'd be interested in, 1. a SOME-TRUST model: a list of opt-outs for the known software that collect telemetry; so that I can just paste that into an env file and be done with it. 2. a ZERO-TRUST model [preferable]: where I control if an application can send any telemetry data; instead of depending on a flag that the distributor may or may not respect.

Default opt-in tracking should be illegal and enforced with such fines and prison sentences, that companies wouldn't even dare to have anything remotely capable of tracking in the runtime.

Unfortunately big corporations can always find away to make regulators see no problem.

I’m morally opposed to the notion of optimizing the opt-out mechanism. I want a standardized opt-in mechanism, like:

  export ALLOW_TRACKING=telemetry,crash_dumps
and the absence of such a setting means “fuck off, don’t spy on me”. It’s not my responsibility to turn off apps wanting to track me. It’s their responsibility to get me to authorize their specific flavor of tracking.

by kstrauser

5/2/2026 at 8:30:35 PM

And they do by burying it in the user agreement you probably agreed to.

by msla

5/3/2026 at 6:20:11 AM

I have some issue with how some of these are represented. For example, syncthing has an explicit opt-in request for telemetry / analytics. The suggested setting change is something entirely different - a call to ask what the latest version is. Granted, that server could log your IP address but that's no different to how it uses the relay and discovery servers that are also run by the same people - those could log the same way.

.. which is entirely different to the telemetry system where usage stats are reported. You can see that on data.syncthing.net. But again, thats a separate opt-in. The suggested env variable on the site won't turn that off.

by darkhelmet

5/2/2026 at 11:17:12 PM

I'm sure this will be about as effective as putting yourself on the do not call list for domestic phone telemarketers, which has absolutely no effect whatsoever on overseas scam call centers.

by walrus01

5/2/2026 at 11:06:43 PM

This does not make sense to support. Businesses that have proper privacy controls and security do not want to be lumped together with random shady apps and want users to explicitly opt out. Another issue with this header is that users could set it and then accidentally opt out of other sharing that they don't realize since this header is being set somewhere random. Standardizing on a per app basis way to revoke consent, along with showing privacy polices and measures the apps have put in place for guarding security would be a more sensible alternative that could gain traction.

by pseudalopex

Honest question, what's the problem with crash dumps that include no personal info? They just help make the software less buggy. I also don't see an issue with anonymized usage patterns (this feature was used X times this month, this one Y times, etc).

Can someone expound on what they see as a problem?

by stavros

5/2/2026 at 8:15:49 PM

> Honest question, what's the problem with crash dumps that include no personal info?

In addition to the other response: crash dumps are difficult to anonymize, both because useful crash dumps include something like a minidump (or some other small alternative to a core file), and because even without that, any random information from a backtrace may be sensitive (e.g. a URL).

There's nothing wrong with saving a crash dump and giving the user control of whether to submit a bug report.

by JoshTriplett

5/2/2026 at 8:17:47 PM

I'm more thinking Python crashes, where you just get the lines that executed, and ~zero identifiable data.

by stavros

5/3/2026 at 8:10:25 AM

Anyone on the path potentially learns something about your system and your software use.

Your IP during connection exposes your rough location.

Crash logs rarely are completely anonymized so both together can additionally serve as a way to re-identify the user.

The only way to properly transmit telemetry data would be Tor. And no, even then I don’t want my tools to report back my use. It’s simply not required, and data minimization is part of my set of ethics, and I’m happy that EU/GDPR sees it the same way. Not all data that you think is worth something to you is morally right to collect. You send data somewhere, even just to check for updates - ask me first. I do not want my hammer to report back how many nails I hammered in. I don’t want my software to reach out to the world without my consent.

by 47282847

5/2/2026 at 7:50:46 PM

I would suggest that the default to enrolling people in supplying such information is the issue. In a world driven by surveillance capitalism, even "anonymous" data can be used for much broader purposes (think, for example, of when and where people are using tools geographically and at what times: you can start to track the behaviour of people in this way).

Users should never be opted in through usage alone of free or paid-for tooling to supply information that isn't part of the function of the tool. Where that is required for a service or product, you should opt-in explicitly, not implicitly.

They expose to the developer that someone was using their software behind that IP address at that time. It also can frequently include private information. The events that occur on my computer are mine and do not belong to the developer of the software.

Hi. I’m the one who made consoledonottrack.com (now expired and squatted) and originally specified and promoted this.

https://web.archive.org/web/20200613155957/https://consoledo...

I abandoned the project. Opting out of telemetry tells developers that opting us in automatically without consent is OK. It’s not.

Spyware is spyware even if it has an off switch.

Patch it out. Fork it. Don’t use spyware. Name and shame developers that accept pay checks to build spyware for corporations. Make it an economically bad choice to accept such jobs by poisoning the google results for the names of people who do this. Make them ashamed.

The one thing you DON’T want to do is validate their unethical model by opting out when you never opted in.

Consent must be explicit, informed and can be revoked at any time.

Tech people could learn a lot from the BDSM community.

Tech companies regularly violate all 3 principles.

1) Opt-out instead of opt-in is an abusive practice, only you're not getting fucked by a strap-on without realizing it, you're getting profiled and manipulated for monetary and political gain.

2) You have no way to find out how your information is used. Ironic in an age where so many decisions affecting you are made by automated systems where the output can be traced back to individual inputs deterministically.

3) Even if you do your research (=spend your limited time alive by playing zero-sum games with no benefit for you) and opt-out, you can't take back what's already circulating out there.

And the solution is not that crazy - change laws so people own all data about them and all results of using said data, except specific well-defined cases.

Then if a company uses your data without your consent, it doesn't pay a probabilistic tax called fines, it is forced to give you a part of its income and a part of its own ownership.

by martin-t

I personally do not use this. The reason is quite simple: I do not want to give out ANY information to external sites. Meaning, they could want to group me into "wants to be tracked" and "does not want to be tracked". I expect a general content blocker, which ublock origin is, to protect me from any malicious external actor, including horrible UI, such as nowadays google search has. I mean, just make a regular google search and then ask yourself why google places so many ads. Yes, ALL links to videos on youtube are also google ads - they self-promote themselves here.

We kind of need ublock origin on the operating system level - even more so as the new laws mandate age sniffing of everyone, tied to usage and access to the www (see the concomitant fight against VPN; that is the long road here, the "but but but the children!" is the lie, the cake, the carrot on the stick).

Ultimately one could ask "but the do not track thing is harmless" - the issue still is that I don't agree that my browser should betray me. Naturally since Google controls most browsers, can we trust Google? But, even aside from Google, can we trust other browsers? We need more diversity here again, but also more quality on every level. I consider the do_not_track as actually a you_will_be_marked and thus tracked.
