Privacy-first & offline-first

Privacy Policy for Thought Stack

Effective Date: August 5, 2026

1. Introduction

Thought Stack ("we," "our," or "us") respects your privacy. This Privacy Policy explains how Thought Stack handles information when you use our Android mobile application.

Thought Stack is built with a privacy-first, offline-first philosophy. We do not collect, transmit, sell, or store your personal data on external servers.

2. Information Handled On-Device

A. Thought Content & Text Input

• What it is: Any text, notes, or thoughts you enter into the application.
• How it is processed: Stored strictly locally on your Android device using an encrypted local SQLite database (Room).
• Server Access: We do not operate external databases or backend servers for this app. Your thoughts never leave your device.

B. Audio & Voice Data

• What it is: Voice input recorded when using the speech-to-text feature.
• How it is processed: Voice audio is processed locally using the standard Android SpeechRecognizer service to transcribe speech into text.
• Server Access: Audio files are not recorded, stored, or transmitted by Thought Stack to any external servers.

3. Permissions Requested

Thought Stack requests only the minimum Android permissions necessary to provide core features:

1. RECORD_AUDIO: Required solely to enable the optional voice-to-text capture feature.
2. POST_NOTIFICATIONS: Required solely to display the persistent notification banner showing your current active thought in your device drawer.

You can revoke these permissions at any time through your Android System Settings.

4. Third-Party Services

Thought Stack does not integrate third-party analytics, advertisement networks, or user tracking SDKs.

5. Data Retention & Control

You have total control over your data:

• You can edit or delete any thought directly inside the app.
• You can clear all completed thoughts or reset application data at any time in the app settings.
• Uninstalling Thought Stack permanently removes all locally stored thoughts from your device.

6. Children's Privacy

Thought Stack does not knowingly collect any personal information from children under the age of 13. The app functions entirely locally without personal data collection.

7. Changes to This Privacy Policy

We may update this Privacy Policy periodically. Any changes will be posted within the application repository or documentation with an updated effective date.
