Privacy Policy — TaskFlow Sync

Effective date: 2026-06-14 · Last updated: 2026-06-14

TaskFlow Sync ("the app") is an offline-first Android task manager. This policy explains what data the app accesses, how it is used, and how to revoke access.

1. Data the app stores on your device

Your tasks (title, note, due date, completion state, snooze time) are saved locally on your device using Android's SharedPreferences store as a single JSON value. The app has no backend; we do not operate any server that stores your tasks.

2. Google account & Google Calendar (optional)

If you choose to sign in with your Google Account, the app requests the OAuth scope https://www.googleapis.com/auth/calendar.events. This scope is used solely to create, update, and delete calendar events that correspond to tasks you have explicitly chosen to sync.

• The app does not read calendar events it did not create.
• The app does not access other Google services (Drive, Gmail, Contacts, etc.).
• Your OAuth refresh and access tokens are stored only on your device, in the platform secure storage provided by Google Sign-In.

3. What we do NOT do

• We do not sell your data.
• We do not share your data with third parties for advertising or analytics.
• We do not transmit your tasks to any server we operate.
• We do not use your Google user data to develop, improve, or train generalized/non-personalized AI or machine-learning models.

4. Permissions on Android

• POST_NOTIFICATIONS — to show task reminders.
• SCHEDULE_EXACT_ALARM — to fire reminders at the exact time you set.
• RECEIVE_BOOT_COMPLETED — to restore reminders after the device reboots.
• RECORD_AUDIO (optional, only if you use voice capture).
• INTERNET (only when you opt into Google Calendar sync).

5. Revoking access & deleting your data

• To revoke the app's access to your Google Account, visit https://myaccount.google.com/permissions and remove "TaskFlow Sync".
• To delete all local task data, uninstall the app or use the "Clear data" option in Android Settings → Apps → TaskFlow Sync → Storage.

6. Children

TaskFlow Sync is not directed to children under 13 and does not knowingly collect data from them.

7. Changes to this policy

If we change this policy, the new version will be posted at this URL with a new "Last updated" date.
