How to find a habit tracker that doesn't want an account

Most habit trackers ask you to sign up before you have tracked anything. It is such a normal first screen that it barely registers as a question, but it is one, and the answer decides where your habit journal lives for as long as you keep it.

What a typical tracker collects

Not every app does all of this, and some do none of it. But the common pattern is:

  • An account: an email address, or a Google or Apple sign-in, tied to everything you record from then on.
  • Your habit data on a server, which is what makes syncing between your phone and your laptop possible.
  • Analytics, often a third-party SDK, reporting which screens you open, how often you return, and which features you use.
  • Crash reporting, which is usually benign and occasionally includes more context than you would expect.
  • An advertising identifier (IDFA) if the app monetises through ads, letting your usage be matched to your activity in other apps.

None of that is unusual, and most of it is boring in isolation. The reason to think about it here is what the data happens to be.

A habit journal is not a to-do list

Look at what people actually track. Not “answer emails”. The list tends to run:

  • Took medication
  • Days sober
  • Therapy homework
  • Meditated
  • Did not self-harm
  • Called my mother
  • Ate a proper meal
  • Went outside today

A list of habits, with dates attached, is a record of someone’s mental health, their recovery, their medical adherence and their worst months. If it includes notes, it is more explicit still. It is the kind of file that, in most jurisdictions, would be regulated as health data if a hospital held it, and a $2.99 app on your phone generally is not held to that standard.

You do not need a threat model involving hackers for this to matter. The realistic risks are duller and more likely: a company changes hands and the privacy policy changes with it; an analytics vendor gets breached; a data set gets sold as “anonymised” and turns out not to be; the app shuts down and nobody can say where the backups went.

The simplest way to not have those problems is for the data never to leave the phone.

Questions worth asking before you install

You can answer most of these from the App Store listing and the app’s privacy policy in about five minutes.

Does it work without an account? If you cannot get past the first screen without an email address, everything you record is going to be associated with it.

Where does my data live? “On device” and “synced to our servers” are very different answers. If an app syncs across devices, it necessarily has a copy. That is not a criticism, it is arithmetic.

What does the App Store privacy label say? Apple requires developers to declare what they collect and whether it is linked to you. It is self-reported, so it is not a guarantee, but a label claiming no data collection is at least a public commitment.

Is there analytics or an advertising identifier? An app that shows no ads and asks for no tracking permission is not building an advertising profile from your sobriety count.

Can I get my data out? Export matters twice over: it is how you leave, and it is how you keep your own backup if the app stores nothing for you.

What happens if the company disappears? If the data is on your device, an app that gets abandoned costs you the app. If it is on their server, it may cost you the record.

The trade-off nobody should hide from you

Local-only storage has a real cost, and any app claiming otherwise is selling you something.

No sync. If your habits only exist on your phone, they only exist on your phone. There is no laptop version, no web dashboard, and no “log in on the new device and everything is there”.

Backup is your job. With no server there is no copy to restore from. What you get instead is your device backup (iCloud or a computer) plus whatever export the app offers.

Losing the phone without a backup means losing the history. That is the honest consequence of nobody else holding your data.

If those costs are unacceptable to you, choose a syncing app with a clear privacy policy and go in knowing the trade. That is a legitimate choice. What is not legitimate is an app that takes the data and does not tell you.

Apps that keep it local

HabitKit is worth knowing about here: no account, data on the device, a free tier, and on both iOS and Android. If you are on Android today it is the local-first option that exists. We compare the two here.

Colors (our app, so weigh this accordingly) is built on the same principle:

  • No account, and no sign-up screen. There is nothing to create, so there is nothing to be logged into.
  • No analytics, no crash-reporting SDK, no advertising identifier, and therefore no App Tracking Transparency prompt, because there is nothing to ask for.
  • Everything on the device. Habits, check-ins, notes and reminders live in a database on the phone. Reminders are scheduled by iOS locally, so there is no push server and no notification is ever sent from us.
  • We hold no copy. Not as a promise about restraint, but as a fact about architecture: there is no server that could receive it.

And the trade-offs, stated plainly, because the section above applies to us too:

  • No sync between devices in version 1. One phone.
  • Your backup is your iPhone backup, iCloud or Finder, which carries the app’s data when you restore onto a new phone.
  • CSV export on Premium if you want a copy you control.
  • iPhone only today, with Android planned after launch.

There is one exception on the website, and it would be silly to write this page and not mention it: if you type your address into the waitlist form on the home page, that address is sent to a form provider so we can email you once at launch. It is described in the privacy policy. Nothing is sent by reading this page.

The short version

A habit journal is health data whether or not the app treats it that way. Ask where it lives, ask whether you can use the app without an account, and ask what you would lose if the company vanished. If the answers are “your phone”, “yes” and “nothing”, the question of who else can read it stops being a question.

The price is sync. Decide whether you want it before you decide which app to install.
