3. Data We Collect

3.1 Data Stored Locally on Your Device

Listido stores all user-created data locally on your device. This includes:

This data never leaves your device unless you explicitly choose to export it using the in-app export feature.

3.2 Crash and Error Reporting

We use Sentry (sentry.io) to collect anonymous crash reports and error data. This data is processed under Art. 6(1)(f) GDPR (legitimate interest in maintaining app stability). Crash reports may include:

Crash reports do not contain any of your personal habit data, mood entries, health information, or any other user-created content.

3.3 Advertising Data (Google AdMob)

The App displays advertisements via Google AdMob, including banner ads, interstitial ads, and rewarded interstitial ads. The data collected by AdMob depends on your age group and consent choices:

3.5 Data We Do NOT Collect

4. Children's Privacy and Age-Appropriate Ads

4.1 Neutral Age Screen

Listido is designed for a general audience, including children. To ensure a safe experience and compliance with COPPA and GDPR, we implement a neutral age screen upon the first launch of the App. We do not store your exact date of birth; we only use this information locally on your device to determine the appropriate privacy settings for your age group.

4.2 Users Under 13 (or Local Age of Consent)

For users identified as being under the age of 13 (or the applicable age in their jurisdiction), we take the following protective measures:

4.3 Users 13 and Older

For users above the age of consent, the App may collect pseudonymous identifiers to provide personalized features and advertisements, provided the user has given their explicit consent through our Consent Management Platform (Google UMP). Without consent, only non-personalized, contextual ads are served.

5. Consent Management

We use the Google User Messaging Platform (UMP) as our Consent Management Platform (CMP) to obtain, record, and manage your advertising consent in accordance with the IAB Transparency and Consent Framework (TCF) v2.2.

6. Data Storage and Security

All personal data (habits, completions, mood, health metrics) is stored exclusively on your device using local storage (AsyncStorage / MMKV). We have no servers that store your personal data and no ability to access it remotely.

We implement reasonable technical measures, including encrypted HTTPS connections for all network requests to third-party services (Sentry, AdMob).

7. Data Retention

8. Data Export and Import

The App provides a manual export/import feature that allows you to:

These actions are initiated entirely by you, and data is shared only through the device's native sharing capabilities.
