Heartwood
Effective 27 August 2026 · Last updated 30 August 2026
The short version. Your habits never leave your iPhone. There are no accounts, no analytics, no advertising, and no trackers. The one thing that does go over the network is your purchase: if you buy Premium, our payments provider checks whether your subscription is active. It never sees a single habit.
This policy explains what Heartwood ("the app", "we", "us") does and does not do with information when you use it. It applies to the Heartwood iOS app and its home-screen and lock-screen widgets.
Nothing you write in the app. Heartwood contains no analytics SDK, no crash-reporting service, and no advertising identifier. Your habit names, dates, streaks, reminders, and settings are never transmitted anywhere.
The app makes network requests for exactly one purpose: verifying whether you have bought Premium. That check is handled by RevenueCat, described in section 5, and involves no information about your habits.
We do not sell, rent, or share personal information about you, and we hold no account, email address, or name that could identify you. We could not tell you who any individual Heartwood user is.
Heartwood needs to remember your habits in order to be useful. It writes that information to a private database inside the app's own storage container on your device, shared with the Heartwood widget extension so widgets can display your progress. This data never leaves your device by any action of ours.
| What is stored | Why |
|---|---|
| Habit name and colour | To label and display each habit |
| Start date and reset history | To calculate your current and longest streaks |
| Display order and hidden/private flag | To lay out your home screen the way you arranged it |
| Reminder settings (days, hour, minute) | To schedule local notifications you asked for |
| App preferences, such as whether App Lock is on | To restore your settings between launches |
You are in control of all of it. Deleting a habit removes its record; deleting Heartwood from your device removes everything the app has stored.
If you turn on a reminder, Heartwood asks iOS for permission to send notifications and then schedules them locally on your device. No push server is involved and no reminder content is transmitted. You can revoke notification permission at any time in Settings › Notifications › Heartwood.
If you enable App Lock, Heartwood asks iOS to authenticate you and receives only a yes-or-no answer. Your biometric data is held in the Secure Enclave by Apple and is never made available to Heartwood, transmitted, or stored by us. If biometric authentication is unavailable or fails, iOS falls back to your device passcode so you cannot be locked out of your own records.
Heartwood Premium is sold through Apple's In-App Purchase system. When you buy a subscription or the lifetime unlock, Apple processes the transaction. Your payment method, billing address, and Apple Account details go to Apple and are never seen by, sent to, or stored by Heartwood.
Apple's handling of that transaction is governed by the Apple Privacy Policy.
To know whether your purchase is still valid, Heartwood uses RevenueCat, a subscription-management service. When the app launches and when you buy or restore Premium, the RevenueCat SDK sends your App Store transaction record, your device's vendor identifier, and basic device and app information, such as your iOS version and country, to RevenueCat's servers. RevenueCat answers a single question — whether an active premium entitlement exists — and Heartwood unlocks features accordingly.
Heartwood does not create an account for you, and never gives RevenueCat your name, email address, or any habit you are tracking. The identifier RevenueCat holds is randomly generated and anonymous, and we make no attempt to connect it to a real person. RevenueCat's handling of this data is governed by the RevenueCat Privacy Policy.
If you back up your iPhone to iCloud or to a computer, that backup may include Heartwood's on-device data, in the same way it includes data from your other apps. Those backups are created and encrypted by Apple under your own Apple Account and are governed by Apple's terms and privacy policy, not by us. We have no access to them.
Heartwood integrates no third-party analytics, advertising, attribution, or data-broker services. Two third parties are involved in your use of the app, both only in connection with purchases: Apple, as the platform vendor and payment processor, and RevenueCat, as the subscription-management service described in section 5. Neither receives any information about the habits you track.
Heartwood is not directed at children under 13 and we do not knowingly collect personal information from anyone, of any age. We hold no accounts and no contact details, so there is nothing identifying a child for us to delete on request.
Privacy laws such as the GDPR and the CCPA give you rights to access, correct, export, and delete personal data a company holds about you. Everything you create in Heartwood lives on your device, where only you can read or change it — through the app itself, or by deleting the app. The only records held off your device are the anonymous purchase records described in section 5; write to us at the address below and we will have them deleted.
If a future version of Heartwood changes what data is stored or introduces any transmission of data, we will update this policy and change the "Last updated" date above before that version ships. Material changes will also be described in the App Store release notes.
