Privacy Policy for Hewn

Last updated: 3 August 2026

Hewn does not collect your data. There is no account, no sign-in, and no server. The app makes no network requests at all, which is a stronger statement than a promise not to misuse data — there is nowhere for it to go.

What Hewn reads, and why

Screen time. How long you spend in apps each day, and how often you open the ones you have marked as feeds. On Android this comes from the system Usage Access permission, which you grant yourself in Settings and can revoke at any time. On iPhone it comes from Apple’s Screen Time APIs, which never reveal to Hewn which apps you chose.
The list of apps that have an icon in your launcher, on Android only, so that you can mark which of them are feeds. Hewn does not read anything inside those apps, and cannot see apps without a launcher icon.
Habits you tick, the discipline you chose, and any daily limit you set yourself.
Camera, only on the “move to another device” screen, and only to read the QR code displayed by your other phone. No photograph is taken, saved or transmitted.

Time spent in Hewn itself, on your home screen, and in the system interface is excluded from your screen-time total.

Where it goes

Nowhere. All of it is stored on your own phone, in the app’s private storage, and never leaves the device. There is no backend service to send it to, so there is nothing for anyone to read, sell, lose, or be compelled to hand over.

Hewn’s home-screen widgets read that same local storage on your device. Nothing is transmitted to display them.

Moving to a new phone is done by showing a QR code on one device and reading it with the other. The information passes directly between your two phones, through the camera, and touches no network.

What Hewn does not do

No analytics, telemetry, or crash reporting.
No advertising, and no advertising identifiers.
No third-party trackers, and no SDKs that contact a server.
No selling or sharing of personal information with anyone, for any purpose.
No profiling, and no automated decision-making.
No push notifications, and no push token registered anywhere.

Notifications

Notifications are composed and scheduled by the app on your own phone. They are not push messages, nothing passes through a server, and their contents never leave the device.

Purchases

If you buy Hewn Plus, the purchase is handled entirely by Google or Apple. They tell Hewn only whether you own it. Hewn never receives your name, card details, or billing address. Those transactions are covered by their policies: Google · Apple

The app store itself

Independently of Hewn, Google Play and the App Store collect their own information about installs, updates, and crashes, under their own privacy policies linked above. That happens at the platform level for every app and is outside Hewn’s control.

Deleting your data

Uninstalling Hewn removes everything it has stored. You can also clear it without uninstalling, from Settings → Apps → Hewn → Storage → Clear storage on Android. Revoking Usage Access in system settings stops any further measurement immediately.

Because nothing is ever transmitted, there is no copy anywhere else to delete.

Children

Hewn is intended for adults and is not directed at children. It collects no data from anyone, including children.

Your rights

Under the GDPR, UK GDPR, CCPA and similar laws you have rights to access, correct, export, and delete personal data held about you by a company. Hewn holds none and transmits none, so there is no request to make and no records to produce. Your data is in your hands, on your phone.

Changes

If this policy changes, the date at the top changes with it. Should Hewn ever begin collecting anything — there is no plan to — it will be stated plainly here and asked for inside the app before it happens.
