Privacy

Last updated 8 September 2026

Clearhead is an app about drinking. That makes this page more important than most, so it is written plainly and it describes what the software actually does.

What stays on your phone

Every drink you log, the days and times you told us are hard, the patterns the app works out from them, your streaks, your notes, your reminder time, and any photograph or drawn face you choose for your profile are stored in a database on your device. They are not uploaded, not backed up to us, and not readable by us. There is no account to create and no email address required to use the app.

The calories and money the app shows are worked out on your phone from what you logged. If you gave the app your height and weight, those are stored on your phone too, and used for one thing: turning calories into minutes of walking for someone your size. The app also shows your body mass index quietly beside them. Neither is ever used to set a limit or make a judgement — no health body publishes an alcohol limit by body weight, and the app will not invent one.

The weekly guidance the app compares you against

When the app says how a week compares, the comparison is with the published low-risk drinking guidance for the country you chose, and it names the source next to the number: the U.S. Dietary Guidelines, the UK Chief Medical Officers, Australia's NHMRC (2020), Canada's Guidance on Alcohol and Health (2023), and Germany's BZgA. These are general public-health figures, not advice about you. The app is not a medical device and does not diagnose anything.

Apple Health

Two things, both optional and both off until you turn them on. In onboarding the app can read your height and weight from Apple Health once, to save you typing them. In Settings you can ask the app to write the drinks you log to Apple Health as alcoholic beverages. Nothing read from Health, and nothing written to it, ever leaves your phone or reaches our server. Health data is never used for advertising or shared with anyone.

Dictated notes

You can speak a note instead of typing it. Transcription uses Apple's on-device speech recognition and nothing else: the app asks for on-device processing and, on a device that cannot do it, the microphone button is simply not offered. The audio never leaves your phone, and we never receive the audio or the text.

Reminders and your calendar

The evening reminder to log is a local notification scheduled on your phone. If you ask for it, the app can also put a matching daily event with an alert into your own calendar, using Apple's calendar access. The app keeps the identifier of that one event so it can move or remove it when you change the time or turn the reminder off. It does not read your other events, and nothing about your calendar is sent anywhere.

What our server receives

If you turn notifications on, the app registers with our server so that a message can reach you even when the app has not been opened. That registration contains a random identifier for your installation, a push token from Apple, your time zone, your app version, and your device language.

The app then uploads the next couple of days of messages: for each one, the exact words and the minute to send it. Because the app writes those messages in your voice, their text can include your first name, the day it is about, and lines from your own plan. That is all. The reasoning that produced them ran on your phone. Our server has never received a drink, a count, a streak, or a reason — and cannot reconstruct them from what it holds.

Sent messages are deleted from our server after seven days. Nothing links your installation identifier to your name, your email, or your Apple ID.

Purchases

Clearhead Pro is a subscription sold by Apple through the App Store. To know whether a subscription is active, the app uses RevenueCat, which receives an anonymous identifier for your installation and your purchase history from Apple — never your name, email, or anything you logged. Apple handles payment, billing and refunds under its own terms.

What the App Store label says, and why

The privacy label on the App Store lists four kinds of data, all used only to make the app work and none used to track you: your name (the first name inside the messages the app uploads), other user content (the text of those messages), a device identifier (the installation identifier and push token), and purchase history (through RevenueCat). Nothing is used for advertising, and nothing is sold or shared with data brokers.

Notifications are written to be unreadable to others

The wording of every message is deliberately neutral, so that someone glancing at your lock screen learns nothing about why the app is writing to you. Check-in questions have answer buttons that say only "Yes" and "No". The app can also be locked with Face ID.

The mailing list

If you enter your email address on this website, we store that address and a confirmation token so we can email you once when the app is released. Confirmation is handled by Resend. This list is entirely separate from the app: nothing joins your email address to an installation, and signing up tells us nothing about your drinking. Every email includes a way to leave.

Analytics

There is no third-party analytics SDK in the app. No advertising identifier is collected, and nothing is sold or shared with data brokers.

Having it forgotten

Turning notifications off in Settings deletes your queued messages. Choosing to be forgotten deletes your device row and everything attached to it — a real delete, not a flag. Exporting and deleting everything the app holds are always available in Settings, subscription or not. Deleting the app removes everything held on your phone. If you would like anything else removed, write to hello@useclearhead.com.

Children

Clearhead is not intended for anyone under 18 and is rated accordingly.

Not medical care

Clearhead is a self-tracking tool. It does not diagnose, treat, or provide medical advice, and it is not a substitute for professional help. Alcohol withdrawal can be dangerous and in some cases requires medical supervision — if you are dependent on alcohol, please speak to a doctor before stopping. The app includes a list of support services and will never discourage you from using them.

Changes

If this policy changes in a way that affects what we hold, the app will say so in plain language rather than quietly updating the date on this page.
