Privacy policy

Privacy for Habit Lab.

Effective date: March 3, 2026. This policy explains how the Habit Lab iOS app and this static marketing site handle user data in the current version of the product.

1. Scope

This policy covers the Habit Lab iOS app and this static marketing site in its English, Polish, Spanish, German, and French versions. It includes local experiment data, iOS notifications, user-initiated sharing actions, and support contact through email.

2. What data may be processed

The app stores data required for product functionality, including selected experiments, setup preferences, intensity, reminder time, day completion state, notes, mood, experiment history, and internal events used to display progress, achievements, and momentum.

3. How the data is used

The data is used to run the app experience: active experiments, reminders, records, history, next-step recommendations, achievements, and sharing screens. In the current codebase, there is no visible external backend that uploads this experiment data away from the device.

4. Where the data is stored

The current implementation stores app state locally on the user's device. That means a local-first model: no visible user account layer, no login, and no visible cloud sync in the current code. Deleting the app from the device will generally remove the local app data from that device.

5. Permissions and external actions

If the user enables reminders, the app may request iOS notification permission. Actions such as copying text, opening a share sheet, or preparing material for a story are only performed after a user chooses to do so. In those cases, data may be passed to the selected third-party app or service under that service's own policy.

6. Marketing site and support form

This site is static. It does not include third-party analytics scripts, advertising scripts, or tracking pixels. The support form does not submit data to a site backend. Instead, it opens the user's local mail client with a prepared email addressed to jan.krzaczkowski@gmail.com.

7. Sharing with third parties

Based on the current code, there is no visible ad SDK, third-party product analytics SDK, or automatic behavioral profiling layer. Data may leave the device only when the user explicitly chooses to share content or send an email.

8. Contact and future changes

For privacy or support matters, contact jan.krzaczkowski@gmail.com or use the support page form. If the product architecture changes in the future, for example by adding a backend, accounts, or analytics services, this policy should be updated to reflect that change.
