Privacy Policy

Landmark reads your health data on your iPhone, keeps it there, and sends it nowhere.

Effective October 27, 2026Version 9

The short version

The Landmark app has no account, no server and no analytics. Every health metric it reads is read on your iPhone, stored on your iPhone, and analyzed on your iPhone. None of it is transmitted to us, because there is nowhere for it to be transmitted to.

The app asks for two other permissions. Your approximate location is used to work out when the sun rises and sets where you are. It is rounded to about 10 km, kept on your iPhone, and never sent anywhere. Notifications are composed on your device from data already on it, and are never sent through a server.

The rest of this page is the detail behind that paragraph.

Who this policy is from

This policy describes how the Landmark iOS app and this website handle your information. It is published by Smashing Labs LLC, referred to below as "we" or "us."

If you have a question about this policy, get in touch via our support page.

What Landmark reads from Apple Health

With your permission, Landmark reads health data from Apple Health so it can show progress toward the targets you set and look for relationships between your behaviors and your results. Depending on which permissions you grant, that can include:

  • Activity: steps, walking and running distance, cycling distance, swimming distance, wheelchair distance, flights climbed, active energy, resting energy, exercise minutes, stand hours, stand minutes
  • Workouts: type, duration, and energy for recorded sessions
  • Sleep: time asleep, and the time you fell asleep
  • Nutrition: dietary energy, protein, carbohydrates, fiber, sugar, total fat and its saturated, monounsaturated and polyunsaturated parts, cholesterol, water, caffeine, and the vitamins and minerals Apple Health records, which are sodium, potassium, calcium, iron, magnesium, zinc, chloride, chromium, copper, iodine, manganese, molybdenum, phosphorus, selenium, folate, niacin, pantothenic acid, riboflavin, thiamin, biotin, and vitamins A, B6, B12, C, D, E and K
  • Alcohol: the number of alcoholic drinks you log
  • Body measurements: weight, body fat percentage, lean body mass
  • Heart: heart rate, resting heart rate, heart rate variability, VO₂ max, and blood pressure, both systolic and diastolic
  • Daylight: time spent in daylight, which iPhone and Apple Watch record
  • Mindfulness: mindful minutes, recorded by a meditation app or Apple Watch's Mindfulness app
  • Date of birth: read once as a fact about you rather than as a measurement, and only to work out your age. Age is what turns a heart rate into a heart rate zone, so this is read only while a heart rate zone goal is available. It is used for that calculation and stored nowhere.

Landmark asks for one permission sheet, once, and every type on it is one a goal, a target or a correlation reads. It does not ask for data it has no feature for: blood glucose, blood oxygen, respiratory rate, body temperature, heart rhythm, hearing, walking and running mechanics, cycling power and cadence, UV exposure, and State of Mind are all absent from the request.

Landmark requests read access only. It does not write anything into Apple Health.

Permission is granted per data type, in Apple Health, and you can change or revoke it at any time in Settings → Health → Data Access & Devices → Landmark. Landmark cannot tell the difference between a data type you have denied and one that has no data in it. That is a deliberate privacy feature of Apple Health, and it applies to us like every other app.

Your approximate location

If you set a daylight goal, Landmark can show how long you have until sunset. Sunrise and sunset depend on where you are, so the app asks iOS for your location to work them out. This is the only thing in Landmark that asks about a place, and it asks for permission only when you tap Show sunset time.

Five things bound it:

  • It is approximate. The app asks for reduced accuracy, which is roughly city-level. It does not ask for your precise position and could not use it. Before keeping a place, the app rounds it to a tenth of a degree, about 10 km.
  • It is while-in-use only. There is no background location, no region monitoring and no tracking of where you go.
  • It is asked for rarely, and each request ends as soon as it answers. The app asks only while a daylight goal is on Today, when you open the app or come back to it, and only if the place it holds is more than 30 minutes old. It takes the first answer and stops. A sunset moves by about a minute a day, so nothing is gained by watching you.
  • It is kept on this iPhone. The app keeps the last place it found in its own storage, so opening it without a new answer still gives the right sun times. It also keeps one record per day in its own database, holding the place it knew that day, your time zone, and the wake and bed times it used. Those records let a past day be judged against its own sunrise and sunset.
  • It is never sent anywhere. Not to us and not to anyone else. It is not in the report Copy diagnostics puts on your clipboard. There is nowhere for it to go.

Deleting Landmark removes the kept place and every daily record, along with the rest of the app's data. If you back up your iPhone, the backup includes them like everything else the app keeps.

Turning Location off for Landmark stops any new request. It does not yet erase the place already kept: that place stays, and each new day's record still carries it, until you delete the app.

If you decline, nothing re-asks and nothing nags. The daylight goal simply shows no countdown. You can change the answer at any time in Settings → Privacy & Security → Location Services → Landmark.

Notifications

Landmark can send you reminders. They are local notifications, which means iOS schedules and delivers them on your device. There is no push server, no device token, and nothing about you leaves the phone when one is scheduled or when one arrives.

Reminders are off by default. The app requests notification permission only when you turn one on, never at launch.

What a reminder says is composed on your device from data already on it: the name of a goal, how much of it is left, and the time. Some reminders are timed from your own recorded history, such as the hour of day you usually finish a habit. That calculation runs on your device against your local database, the same as every other calculation Landmark performs. We never see the content of a notification or the fact that one was sent.

You can turn reminders off inside Landmark, or revoke the permission entirely in Settings → Notifications → Landmark.

What Landmark stores, and where

Everything Landmark records is stored in the app's own database on your device: the inputs you configure, the goals you set, the results it computes, and the one record per day described under your approximate location. That database is covered by your iPhone's own encryption.

We do not operate a server that receives your health data. There is no Landmark account to create and no credential to give us.

Landmark does not use iCloud. It has no CloudKit container and syncs nothing to your iCloud account, so no health data is stored there by the app.

The one exception is your own device backup: if you back up your iPhone to iCloud or to a computer, the app's database and its kept place are included in that backup like every other app's data, and are then governed by the terms of whichever backup you chose. That backup is between you and Apple; we have no access to it.

What we do not do

  • We do not sell your data.
  • We do not share your health data with advertisers, data brokers, or any third party.
  • We do not use your health data for advertising or profiling.
  • We do not embed third-party analytics or tracking SDKs in the app.
  • We do not use your data to train machine-learning models.

Insights are computed on your phone

Landmark's insights come from correlating your own history. That is the analysis that produces lines like "when you sleep at least eight hours, your active calories the following day are higher." It runs on your device against your local database. Your data is not uploaded for processing.

Information Apple gives us

If you choose, in your own iOS settings, to share analytics and crash reports with app developers, Apple may give us aggregated crash logs and App Store usage statistics. This is Apple's mechanism, not ours: it is controlled in Settings → Privacy & Security → Analytics & Improvements, it contains no health data, and it does not identify you.

Apple also gives us aggregated App Store download figures. They contain no health data and do not identify anyone.

This website

This site is a set of static files. It asks you for nothing, and it never sees your health data. Our hosting provider, Netlify, keeps standard server logs of requests, which can include IP addresses, for a limited period for security and operational purposes. See Netlify's own privacy policy for how it handles that data.

The site uses Google Analytics to count visits, see which pages people read, and count taps on the App Store link. It sets cookies in your browser, and it sends Google your IP address, the pages you open, and basic details about your device and where you came from. See Google's own privacy policy for how it handles that data. You can block it with a content blocker or your browser's own settings, and the site works the same either way.

The app shows these policies inside itself, by loading them from this site. That is what keeps the wording you read current. Those pages are served without the analytics tag, so reading a policy in the app is not measured. The request carries no health data, and it reaches Netlify's logs the same way a visit from a browser does.

If you email support, we will have your email address and whatever you put in the message, and we will keep it only as long as needed to answer you.

Deleting your data

Deleting the Landmark app from your iPhone deletes its database and everything in it, including the place it keeps. Because that data was never sent anywhere, there is nothing left on our side to delete.

Revoking Landmark's Apple Health permissions stops any further reading immediately. Data Landmark has already read remains in its local database until you delete the app.

Children

Landmark is not directed at children under 13, and we do not knowingly collect information from them. Given that we collect nothing, this is a statement of intent rather than a data-handling practice.

Your rights

Depending on where you live, you may have rights to access, correct, export, or delete personal information a company holds about you, under the GDPR, the CCPA, or a comparable law.

We hold no health data about you, so there is nothing for us to hand over or erase. Everything the app reads is Apple Health's data on your iPhone: the Health app is where you see, correct, export, or delete it. Deleting the Landmark app removes its own copy. For anything else, such as an email you sent support, get in touch via our support page and we will act on it.

Changes to this policy

If this policy changes, we will update the version and effective date at the top of this page. Substantive changes will be surfaced in the app.
