Revision: 1.2

Revision History

1. Introduction

This Privacy Policy describes how Sia Makerlab ("we," "us," or "our") collects, uses, and shares information in connection with your use of the Quick Notes mobile application (the "App").

By downloading, installing, or using the App, you agree to the collection and use of information in accordance with this Privacy Policy. If you do not agree with this Privacy Policy, please do not use the App.

2. Information We Collect

2.1 Information You Provide

The App is designed to function without requiring you to create an account or provide personal information. We do not collect:

• Names or email addresses
• Phone numbers
• Physical addresses
• Payment information (processed entirely by Google Play)

2.2 Information Collected Automatically

2.2.1 Local Device Storage

The App stores the following data locally on your device only:

This data is stored exclusively on your device using Android DataStore and/or the Room database. We do not have access to this data, and it is never transmitted to our servers.

2.2.2 Quick Access Entry Points (Local Only, Opt-In)

The App provides six system-wide entry points that let you create or search notes from outside the App. Each entry is off by default and is enabled individually from Settings → Quick Access. None of these entries require any permission beyond the App's existing permissions; they use standard Android system APIs.

Toggling any of these entries on or off only updates a local DataStore flag and, for the OS-level entries, calls PackageManager.setComponentEnabledSetting on the relevant component. No telemetry is sent.

2.2.3 Call State Information (Local Only, Opt-In)

If — and only if — you explicitly enable the call-memo feature and grant the required runtime permissions, the App observes the call state of your device (idle / active / ended) and the direction of the call (incoming / outgoing) in order to display the floating composer at the appropriate moment.

• The call state is read in-memory via Android's TelephonyCallback (API 31+) or PhoneStateListener (API 24–30) and is never persisted, logged, or transmitted.
• The App does not access the phone number of the remote party, call duration, call logs, contacts, microphone audio, or any other call content.
• Note text you choose to save through the overlay is stored in the same local Room database as your other notes.
• The call-memo master switch defaults to OFF. The feature is inactive until you turn it on.
• On Android 14+, the call-memo foreground service is declared with the specialUse foreground service type. The subtype is declared via PROPERTY_SPECIAL_USE_FGS_SUBTYPE ("phone_call_memo"); no additional data is collected as a result of this declaration.

2.2.4 Home-Screen Widget

The App provides a Glance home-screen widget that displays a read-only view of your most recent notes plus a "+ New note" entry button that opens the App's editor. The widget reads data from the same local Room database; no additional data is collected or transmitted.

2.2.5 Advertising Data (Third-Party)

The App displays advertisements through Google AdMob. Our advertising partner may collect:

• Advertising ID (Android Advertising ID)
• Device information (device type, operating system version)
• IP address
• General location data (country/region level)
• Ad interaction data

The App displays the following types of ads:

• Adaptive Banner Ads — displayed at the bottom of the screen
• App Open Ads — full-screen ads displayed when the App is launched or returns from the background, subject to internal frequency capping

This data collection is governed by Google's Privacy Policy: https://policies.google.com/privacy

2.2.6 EU Consent (Google UMP)

For users in the European Economic Area, the United Kingdom, and Switzerland, the App integrates the Google User Messaging Platform (UMP) to obtain and manage your consent for personalized advertising. Your consent choices are stored on your device by the UMP SDK and can be revisited at any time from Settings > Privacy & Data > Manage Privacy Settings.

2.2.7 In-App Purchase Data (Third-Party)

If you make an in-app purchase to remove advertisements, the transaction is processed entirely by Google Play. We receive only:

• Confirmation of purchase status
• Transaction ID for verification purposes

We do not receive or store any payment card information, billing addresses, or other financial data.

2.2.8 In-App Review (Third-Party)

The App may invite you to rate it through the native Google Play in-app review flow. The review experience is rendered and submitted by the Play Store; we do not collect or process the review content.

2.3 Information We Do NOT Collect

We explicitly do not collect:

• Note content transmitted to servers (stored locally only)
• Text passed in through the share sheet, the App Actions voice intent, or the text-selection menu (stored locally only)
• The phone number, identity, or audio of any party to a call
• Call logs, contacts, or messages
• Personal information
• Precise location data
• Camera or microphone data (Google Assistant's microphone use for voice dictation is governed by Google's privacy policy, not ours)
• Browsing history

3. Permissions

The App declares the following permissions. The five OS-level Quick Access entries (App Shortcuts, Quick Tile, Share sheet, App Actions, Process Text) require no additional permissions. Permissions related to the call-memo feature are runtime-prompted and the feature is off by default.

You can revoke any of these permissions at any time from Android system settings.

4. How We Use Information

4.1 Local Data Usage

4.2 Third-Party Data Usage

Data collected by third-party services (Google AdMob, Google Play, UMP, Google Assistant) is used to:
