1. Introduction

Daily Notifier (“the App,” “we,” “us,” or “our”) is published by Tech Studio Worlds. It is a reminder and personal productivity application for Android devices.

This Privacy Policy describes how Daily Notifier handles information when you use:

  • Local productivity events — used only on-device to calculate scores, streaks, charts, and dashboard summaries

2.3 Information collected by third-party services

Google AdMob (Advertising)

When advertisements are shown, Google AdMob may collect and process information under Google’s Privacy Policy, which may include:

  • Advertising ID (AAID/GAID)
  • IP address and device information
  • Ad interaction and diagnostic data
  • Approximate location derived from IP (where permitted by law)

Your productivity content is not shared with Tech Studio Worlds through AdMob.

Ad formats in this App: adaptive banner ads and interstitial ads (limited to certain navigation exits, with session frequency caps). Rewarded ads and app-open ads are disabled in the current App release.

Ads are implemented in compliance with Google Play and AdMob policies, including dedicated ad placement areas that do not overlap core action controls.

Firebase Crashlytics (Conditional)

If the App is built with Firebase configuration (google-services.json), Firebase Crashlytics may collect crash logs, stack traces, and related diagnostic data. This is used to improve stability. Crashlytics is not intended to collect your reminder text, notes, or other personal productivity content.

3. Information We Do Not Collect

Daily Notifier does not:

  • Require registration, login, or user accounts
  • Collect your name, email address, or phone number through in-app forms
  • Upload reminders, notes, habits, expenses, mood entries, or focus tasks to Tech Studio Worlds servers
  • Access contacts, SMS, call logs, photos, or precise GPS location
  • Use the device camera
  • Operate cloud backup or sync to developer servers
  • Sell your personal data

5. Local Data Storage

  2. SQLite — productivity.db (habits, tasks, notes, goals, expenses)
  3. Room database — productivity_v2.db (life scores, mood journal, focus tasks, knowledge vault metadata, analytics rollups, routines, streaks, XP, insights)
  4. App-private files — voice recordings saved as .m4a files

Automatic cleanup: Reminders older than 30 days may be removed locally by the App.

Android backup: The App has android:allowBackup="true". Depending on your device and Google account settings, Android may include App data in encrypted device backups. We do not control Google’s backup systems.

No developer cloud storage: We do not maintain servers that store your productivity or reminder content. If cloud sync is introduced in a future version, this policy will be updated and appropriate consent will be requested where required by law.

6. Reminder Features

Daily Notifier allows you to:

  • Create, edit, and delete reminders
  • Schedule exact-time alerts using Android AlarmManager
  • Receive notifications through NotificationReceiver
  • Play alert audio through AudioService (foreground media playback)
  • Automatically reschedule reminders after reboot via BootReceiver

Reminder content is displayed only on your device. We do not transmit reminder messages to Tech Studio Worlds servers.

7. Voice Recording Features

You may optionally:

  • Record a voice message using the device microphone (RECORD_AUDIO)
  • Select a music/audio file from your device (READ_MEDIA_AUDIO / READ_EXTERNAL_STORAGE on older Android versions)

Voice recordings are saved in the App’s private external files directory. File references are stored with the associated reminder. Recordings are not uploaded to our servers. Deleting a reminder removes its associated reference; you may also clear all App data through Android system settings.

8. Productivity Features

Through the Productivity Hub, the App provides on-device tools:

FeatureDescription

To-Do List
Manage tasks with priority and due dates

All productivity data remains on your device unless you choose to share content outside the App using Android’s share functionality.

A daily background task (WorkManager, every 24 hours) refreshes dashboard data on your device only.

Dates and times in Life features use locale-aware formatting per your device settings.

10. Advertising (Google AdMob)

Daily Notifier uses Google AdMob to display advertisements.

What is shown:

  • Banner ads — adaptive banners in dedicated containers on selected screens when content is present
  • Interstitial ads — shown only on limited navigation exits (e.g., leaving the productivity hub or modules, exiting the App), subject to frequency limits (maximum per session and minimum time between ads)

What is not shown (current version):

  • Rewarded ads (disabled)
  • App-open ads on splash or onboarding (disabled)
  • Ads on reminder creation/edit screens

Important:

  • Your productivity and reminder data is NOT shared with Tech Studio Worlds servers.
  • AdMob may collect advertising identifiers and related data as described in Google’s policies.
  • Ads are placed to comply with Google Play and AdMob policies, including measures to reduce accidental clicks and UI overlap with core controls.

You may limit ad personalization through your device’s Google Ads settings and Android advertising ID controls.

  • In-app legal pages (WebView) are restricted to approved HTTPS hosts
  • No Tech Studio Worlds servers receive your reminder or productivity content

No security method is perfect. You are responsible for securing your device (screen lock, OS updates, etc.).

13. International Users

  • Formats dates, times, numbers, and currency according to your device locale
  • Does not transmit locale or regional settings to Tech Studio Worlds servers

Expense amounts, dates, and times automatically adapt to regional conventions (for example, United States, United Kingdom, European Union, Japan, or other regions supported by the device).

14. GDPR & User Rights

If you are located in the European Economic Area (EEA), United Kingdom, or Switzerland, or other jurisdictions with similar laws, you may have rights including:

  • Access — request information about processing
  • Rectification — correct inaccurate data
  • Erasure — request deletion
  • Restriction — limit certain processing
  • Objection — object to certain processing
  • Data portability — receive data in a portable format (where applicable)

Locally stored App data: Because your content is stored on your device and not on our servers, you can delete it by removing individual items in the App, clearing App storage in Android Settings, or uninstalling the App.

AdMob and Crashlytics data: Managed by Google under its privacy policies and your Google/device settings.

Legal bases (EEA/UK): Local App functionality is provided at your request to perform the service you use. Advertising-related processing by Google is governed by Google’s legal frameworks and your consent or legitimate interests as applicable.

You may lodge a complaint with your local data protection authority.

15. Children's Privacy

Daily Notifier is intended for a general audience and is not directed at children under 13 (or the applicable age of digital consent in your jurisdiction).

We do not knowingly collect personal information from children through Tech Studio Worlds servers. If you believe a child has provided information through the App, contact us at techstudioworlds@gmail.com and we will assist with appropriate deletion steps (primarily clearing App data or uninstalling the App on the device).

16. Data Deletion

You may delete your data at any time:

MethodResult
Delete individual items in the App
Removes that entry from local storage
Settings → Apps → Daily Notifier → Storage → Clear data
Deletes all local databases, preferences, and recordings
Uninstall the App
Removes App data from the device (subject to Android backup settings)

We do not retain copies of your productivity or reminder content on our servers because we do not collect it centrally.

For AdMob or Crashlytics data, use Google’s privacy and account tools.
