YOUR INFORMATION

Privacy policy

Starbuck Note Taker is an offline-first Android app. Your notes live on your device. Optional connected features have specific data flows, explained here.

Effective 4 November 2026 · Published by Nick Price

1. Notes and device storage

The app stores notes and attachments in Android app storage. Notes use encrypted local storage with a key derived from your PIN. Protected-note and archive features let you protect selected content. When you use biometric unlock, Android handles authentication; the app does not receive fingerprint or face templates.

The app may also store settings, reminder information, link previews, downloaded AI model files and cached public research results on the device. Android backup and device transfer depend on your device and backup settings. Exported archives and files shared with another application are controlled by you and the destination application.

2. Google Calendar access

Google Calendar sync is optional. When you choose Link Google Calendar, Google handles account selection and authorisation. The app does not receive or store your Google password.

The app requests permission to access Calendar events and an OpenID permission to identify the authorised Google account. The account identifier is used to prevent synchronisation changes from crossing into a different linked account.

Information accessed and why

The app reads event identifiers, titles, descriptions, start and end dates/times, all-day status, time zones, locations and recurrence-related metadata returned by Google Calendar. It uses this information to display local calendar events, create local event notes, support reminders, and synchronise changes that you choose.

Google's event permission can cover all your calendars. The current synchronisation implementation targets your primary calendar and provides these directions:

Sync is requested after local event additions, edits and deletions, when you unlock the app, and when you choose Sync now. Offline changes may remain pending until a later sync.

Storage and protection

Downloaded events are stored with the app's local notes. The linked account identifier, synchronisation settings, event/deletion identifiers and pending deletions are stored in encrypted preferences. Access tokens are held in memory; Google Play services manages authorisation grants and token renewal.

Protected events are excluded from uploads and remote overwrites. Protecting an event that was previously uploaded does not delete its existing Google copy. Calendar sync does not upload attachments.

Google data use and sharing

Google Calendar data is used for the app's visible calendar, note, reminder and synchronisation features. Imported event text becomes local note content and may be included in on-device AI assistance when you use those features. It is not used to train a generalised AI model. Connected research and sharing actions can transmit the specific queries, links or content described below.

The app does not sell Google user data or use it for advertising, data brokerage, credit decisions or unrelated profiling. It does not provide developers with routine access to the contents of your local notes or calendar.

Starbuck Note Taker's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including its Limited Use requirements.

3. Other network features

Google and other providers process information they receive under their own applicable privacy policies. Opening a website, sharing a note or exporting a file can disclose the information you select to its destination.

4. Retention, deletion and disconnecting

Local notes, downloaded event copies and synchronisation metadata remain until you delete them or clear the app's storage. The app may keep public research results in a bounded, temporary cache. Exported archives, other applications, Android backups and Google Calendar hold separate copies that you manage separately.

Deleting a local event can delete the Google event when your sync direction permits uploads. An offline deletion can be applied to Google on a later sync. Google's retention of information in its services is governed by Google's policies.

Disconnect Google Calendar stops subsequent sync requests. It does not delete existing local copies or Google events, and does not itself revoke Google's grant. To revoke access, use your Google Account's third-party connections settings. You can remove local data with the app's deletion features or Android app-storage controls.

For questions or requests about information under the publisher's control, including hosting logs, use the contact below. Do not send private note contents, credentials or calendar exports unless they are necessary for a request you choose to make.

5. Changes to this policy

This page identifies its effective date. Material changes to the use of Google data require appropriate disclosure and consent before the changed use begins.
