1. Overview & Core Philosophy

At Aievio, we believe your personal milestones, celebrations, and life events are deeply private. DayMarker is built from the ground up as a Local-First, Zero-Surveillance application.

  • We do not sell, rent, monetize, or broker your personal data.
  • We do not use third-party analytics trackers, advertising SDKs, or behavioral profiling tools.
  • All countdown records, dates, titles, and journal entries are stored encrypted locally on your physical device.

2. Google API Services User Data Policy Compliance (Limited Use Disclosure)

DayMarker offers an optional cloud backup and synchronization feature utilizing the Google Drive Application Data Folder (https://www.googleapis.com/auth/drive.appdata).

Strict Scope Limitation

  • Isolated Sandbox: DayMarker only requests access to its own private, isolated configuration and backup directory (drive.appdata).
  • Zero Access to Personal Files: DayMarker cannot read, view, modify, list, or delete any of your personal Google Drive documents, spreadsheets, photos, or files.
  • No External Servers: Backups travel directly between your device and Google's servers over TLS encryption. No intermediary servers, proxies, or analytics pipelines ever touch your backup payload.

Google Limited Use Affirmation

DayMarker's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements:

  1. We only use Google user data to provide user-facing features (specifically: cross-device backup and restoration of your milestone countdowns).
  2. We do not transfer Google user data to third parties.
  3. We do not use Google user data to serve advertisements, train machine learning models, or conduct behavioral targeting.
  4. Human access to Google user data is strictly prohibited.

3. Data We Collect and Store

A. Data Stored Locally on Your Device

  • Event Metadata: Event titles, countdown target dates, recurring intervals, categories, and custom color tags.
  • Celebration Memories: Personal reflection notes and milestone completion logs.
  • User Preferences: Theme selection (Light, Dark, High-Contrast), notification times, and widget layout preferences.

This data is stored inside a local SQLite database on your device and is never transmitted to our servers.

B. Device Permissions

DayMarker may request the following platform permissions strictly to provide core features:

  • Notifications (POST_NOTIFICATIONS): Used solely to alert you when an upcoming countdown or milestone anniversary arrives.
  • Calendar (READ_CALENDAR / WRITE_CALENDAR): Optional. Used exclusively when you choose to import events from or export events to your device calendar.
  • Storage / Photos (READ_MEDIA_IMAGES): Optional. Used solely to let you pick a background photo from your gallery for custom event cards.

4. Third-Party Services & Zero Analytics

DayMarker does not include:

  • Google Analytics for Firebase
  • Meta / Facebook Graph SDK
  • AppsFlyer, Adjust, or Kochava
  • AdMob or third-party ad networks

5. Data Retention, Portability & Deletion

  • Local Deletion: You can delete individual events or purge all data at any time via DayMarker's in-app settings.
  • Backup Deletion: If you enabled Google Drive sync, you can delete your backup at any time from within DayMarker or by visiting Google Drive → Settings → Manage Apps → DayMarker → Delete hidden app data.
  • Universal Export: You can export your complete milestone history to a clean JSON or CSV file at any time.

6. Children's Privacy

DayMarker does not knowingly collect or solicit personal information from children under the age of 13. The application is completely safe for all audiences.
