Privacy Policy
Last updated: 2026-04-13
This privacy policy describes how DoneDay Habit Tracker ("doneday", "the app"), developed by teraken-dev ("we", "us"), collects, uses, and shares information. This policy applies to the app distributed through the Apple App Store and Google Play Store.
1. Overview
doneday is a habit tracking app that lets you create habits, mark them as completed, and review streaks and recent progress. The app is designed to work fully offline with no user account required.
2. Data Stored Locally on Your Device
The following data is stored locally on your device using AsyncStorage and is never sent to our servers:
- Habit names, icons, and colors
- Completion logs and dates
- Streak and statistics data
- App preferences and settings
This data stays on your device and is deleted when you uninstall the app.
3. Data Collected by Third-Party SDKs
The app integrates third-party SDKs that may automatically collect certain data. We do not control the data collection practices of these SDKs.
3.1 Google AdMob (Google Mobile Ads SDK)
The app displays advertisements through Google AdMob. The AdMob SDK may collect:
- Device identifiers: Advertising ID (Android), IDFA (iOS)
- Device information: Device model, OS version, screen size, language
- IP address (used for approximate location and fraud prevention)
- App interaction data: Ad impressions, clicks, and engagement
- Diagnostic data: Crash logs, performance metrics
The app requests non-personalized ads only (requestNonPersonalizedAdsOnly: true).
However, the AdMob SDK may still collect device identifiers and diagnostic data as described above.
For more information, see the Google Privacy Policy and Google AdMob & Data.
3.2 RevenueCat
The app uses RevenueCat to manage in-app purchases. RevenueCat may collect:
- Purchase history: Transaction data, product identifiers, purchase dates
- Device identifiers: Anonymous app user ID, vendor ID
- App interaction data: Subscription status, entitlement checks
For more information, see the RevenueCat Privacy Policy.
4. Purpose of Data Collection
| Data Type | Purpose | Collected By |
|---|---|---|
| Device identifiers | Third-party advertising, analytics | Google AdMob |
| App interaction data | Ad delivery, analytics | Google AdMob |
| Diagnostic data | App stability, performance monitoring | Google AdMob |
| Purchase history | App functionality (ad-free entitlement) | RevenueCat |
5. Data Sharing with Third Parties
We do not sell your personal data. Data collected by third-party SDKs may be shared with their respective services as follows:
- Google AdMob shares ad interaction data with Google's advertising network for ad delivery and measurement.
- RevenueCat shares purchase data with Apple App Store / Google Play for transaction validation.
6. In-App Purchases
The app offers a one-time purchase to remove advertisements. Purchase processing is handled by the Apple App Store or Google Play Store. Purchase status is managed through RevenueCat. We do not have access to your payment information (credit card number, billing address, etc.).
7. Tracking
The app does not implement Apple's App Tracking Transparency (ATT) framework and does not track users across other apps or websites. The app requests non-personalized ads only.
8. Data Retention and Deletion
All habit data is stored locally on your device. Uninstalling the app permanently deletes all local data. The app does not have user accounts, so no server-side account deletion is required.
Data collected by third-party SDKs (Google AdMob, RevenueCat) is retained according to their respective privacy policies and retention schedules.
9. User Rights
For users in the European Union (GDPR)
You have the right to access, correct, delete, and port your personal data, and to object to processing.
For users in California (CCPA)
You have the right to know what data is collected, to request deletion, and to opt out of the sale or sharing of personal information. We do not sell personal information.
To exercise any of these rights, contact us at the email address below.
10. Children's Privacy
The app is not directed to children under the age of 13 (or the applicable age in your jurisdiction). We do not knowingly collect personal information from children. The app's target audience is ages 18 and above.
11. Notifications
The current version of the app does not actively provide push notification features.
12. Changes to This Policy
We may update this privacy policy from time to time. Changes will be posted on this page with an updated "Last updated" date. Continued use of the app after changes constitutes acceptance of the revised policy.
