A private quit smoking app with no account, checked rather than promised

"No account" and "no data leaves the device" get treated as one claim. They are two different claims, and both are things you can check yourself before you install anything.

Written by Lee H. Last reviewed 5 August 2026.

Here is the conflict of interest, stated plainly instead of buried: I am building The Long View, a quit smoking app of my own, and this website exists to support it. A page about which app is the most private is exactly the kind of thing a competing developer has an incentive to slant, so check the sources below yourself rather than taking my word for any of it. The Long View does not ship yet, on any platform, so it is not being compared against apps you can actually download today. It gets its own section near the end, marked clearly as a design intent and not a finished product.

If you searched for this, what you probably want is simple: you don't want a record of your smoking, how much, how often, how long you've been trying to quit, sitting on somebody's server with your email address attached to it. That's not a paranoid thing to want. Smoking history is health information, quitting is something plenty of people would rather keep to themselves, and "an app on my phone knows this" feels very different from "a company's cloud knows this." The rest of this page is about how to actually get the first one, rather than how to feel reassured about it.

What "private" has to break down into

"Private" by itself is just a word a listing puts in its subtitle. It only becomes useful once you turn it into questions you can answer with a yes or no, for any app, not just the ones named here:

• Does it require an account to use the core features: an email address, a phone number, or a mandatory sign-in with Apple or Google?
• Does any data leave the device, for any reason, including an optional backup, not only a mandatory account?
• Is there advertising or a third-party analytics kit bundled in, whether or not you ever see an account prompt?
• What does the app's own store listing disclose, in the App Store's Privacy section or Google Play's Data Safety section, the places a developer is required to state this rather than just imply it in marketing copy?

The next few sections go through each of those, using two real listings I checked while writing this as worked examples. Neither is accused of anything here. The point is to show what each check actually looks like, so you can run it yourself on an app this page never mentions.

No account is not the same as no data leaving the device

These get conflated constantly, and they are answers to different questions. "No account" means nobody made you type in an email address or a phone number to start using the app. "No data leaves the device" means the bytes never go anywhere else, by any route, ever. An app can clear the first bar and still fail the second, because backup, crash reporting and analytics can all move data off a phone without ever asking who you are.

This is a clean, honest example of the distinction, not a criticism of the app. Its own Play Store description leads with local-first storage and calls out the optional Google Drive backup by name, so nothing here is hidden. No account is required to use it, and data can still leave the device the moment that backup is switched on, because a copy sitting in your Google Drive is data that has left the device, even though nobody ever collected your email address to put it there. Google Play's own Data Safety section for this app, which I read directly rather than trusting the marketing copy, states that it collects app activity, approximate location, device identifiers and diagnostic data, declared for analytics rather than for advertising or for sale to a third party, and states that it does not offer a way to request deletion of that data. None of that contradicts "no account." It just means "no account" was never a promise that nothing leaves the device, and the two need checking separately.

Reading the App Store's own privacy label

Every iOS app has a Privacy section on its own product page, below the description, listing categories the developer has declared under Apple's required nutrition-label format: Data Not Collected, Data Linked to You, Data Not Linked to You, and Data Used to Track You (the category tied to the App Tracking Transparency prompt, the one that asks permission to track you across other companies' apps and websites). It is self-reported by the developer, not independently audited by Apple, but a developer who misstates it is violating the App Store's own guidelines, so it carries more weight than a tagline and it takes about ten seconds to check on any app before you install it.

This is a different app from the Android one above, from an unrelated developer, that happens to share the same name; more on that below. Its own App Store description leads with almost exactly the pitch this page is about: your journal and data stay on your device, no account, no sign-up, start instantly, and, in its own words, "anonymous analytics only, nothing sold." That last line is already more candid than most listings bother to be. Checking the App Store's own Privacy section for this same listing shows Purchases, an Identifier described as a User ID, and Usage Data described as Product Interaction, all listed under Data Linked to You for an Analytics purpose. That is consistent with what the description says, an identifier tied to anonymous usage analytics rather than a login, but it is a more precise statement than "anonymous analytics" on its own, since the label is explicit that an identifier is linked to your data even though no account exists. That precision is exactly why the label is worth reading even when a developer is already being upfront in its own description.

Reading Google Play's Data Safety section yourself

Android's equivalent lives in a Data Safety section on the app's own Play Store listing, also filled in by the developer rather than verified by Google. It states plainly whether any data is shared with other companies, then lists what is collected, broken into categories such as location, personal info, app activity, device or other IDs, and app diagnostics, each tagged with why it is collected (app functionality, analytics, advertising, and so on), and finally a short list of security practices: whether data is encrypted in transit, whether you can ask for it to be deleted, and similar. The Smoke Tracker (Android) example above is what that section looks like in practice: no third-party sharing declared, several categories collected for analytics, and no deletion mechanism offered. Reading it takes less time than reading a full privacy policy, and it is the same format on every app in the store, so it is worth the habit regardless of which app you end up choosing.

Advertising and third-party analytics

A quit smoking app can clear "no account" and still run on ad revenue, which usually means a third-party advertising kit is bundled in alongside whatever the app tracks about your quitting. EasyQuit, discussed on the best quit smoking apps guide as a free, ad-supported, no-account option, is a good example to check rather than a bad app to single out: its own App Store Privacy section lists Identifiers and Usage Data under Data Used to Track You, the App Tracking Transparency category, and lists Third-Party Advertising, specifically a device ID and advertising data, under Data Not Linked to You. That is the label version of "supported by ads," and it is worth knowing that a no-account app and an ad-funded app are not opposites. They are two separate questions with two separate answers, again both printed on the same page.

Where Smoke Tracker fits, and a naming coincidence worth knowing about

Of everything I checked for this page, Smoke Tracker markets the no-account, on-device position harder and more specifically than anything else in the category, and its own published description backs that up on both platforms: local storage, no account, no sign-up, described plainly rather than hinted at. Worth knowing before you search for it: it is two unrelated apps, one on each store, from two different developers, that happen to share a name and a nearly identical pitch. That is either a coincidence or evidence that "no account, local-first" is a real market position more than one developer has decided is worth building for, not a slogan invented by one company. Either way, if you are choosing between a phone and a tablet running different platforms, check the developer's name in the listing, not just the app's title, since a store search will happily return an unrelated app that shares a name with the one you meant.

What The Long View is built for, and why that is not the same as a product

Here is the design intent for The Long View, disclosed as exactly that: an intent for an app that has not shipped, not a claim about a product you can install today. It is designed to ask for no account, no email address and no payment details inside the app itself. Your entries and your photo are meant to stay on your device. Where sync exists on Apple platforms, iPhone, iPad, Apple Watch and Mac, it is designed to run through your own private iCloud container, which belongs to your Apple ID and which the developer cannot read. On Android, the plan is Auto Backup to your own Google account, which backs your data up and restores it on a new device or after a reinstall; that is backup and restore, not live sync between two devices in use at the same time, and it is a different mechanism from iCloud for that reason. Full detail is on the privacy page. None of this can be checked the way the App Store and Play Store labels above can be checked, because there is no listing yet, and a promise is not a product. Read it as a stated intention, hold it to the same standard once it ships, and do not take it on faith in the meantime.

What you can already check today

Whatever the app eventually does, the calculators on this website run entirely in your own browser right now, and send nothing anywhere. That is not a promise about the future, it is how the page works today, and you do not have to trust me on it: open your browser's network inspector while using the quit smoking calculator and you will see it make no requests to any server at all. The privacy page covers what that means for this site as a whole, kept separate from what the app itself is designed to do.

Nothing on this page diagnoses, treats or prevents any condition, and none of it is medical advice. Talk to a doctor or a quitline about stopping smoking. In the US, that is 1-800-QUIT-NOW.
