Privacy Policy

Your data stays yours. TabMod is designed for privacy by default.

Last updated: October 8, 2026

Introduction

TabMod ("we", "our", or "us") is a Chrome extension that helps you manage, organize, and sync your browser tabs. We are committed to protecting your privacy. This policy explains what data we handle, how we handle it, and your rights over that data.

Our core principle: all data stays on your device by default. TabMod is designed to work fully offline without any data leaving your computer. Cloud sync is an optional feature that you must explicitly enable.

Privacy by design: we collect the absolute minimum needed for the extension to function. No tracking scripts, no analytics cookies, no third-party data sharing.

1. Data We Collect

1.1 Local data (always stored, never transmitted)

When you use TabMod, the following data is stored exclusively on your device using Chrome's built-in chrome.storage.local API:

Data	Purpose	Storage
Tab URLs and page titles	To display your saved tabs in organized lists	Local only
Workspace and folder names	To organize tabs into named groups	Local only
Extension settings (theme, language, etc.)	To remember your preferences	Local only
Anonymous usage counters	To show you stats (tabs saved, memory saved)	Local only

We never have access to this data. It never leaves your computer unless you explicitly enable cloud sync.

1.2 Cloud sync data (optional)

If you choose to enable cloud sync, the following data is transmitted to our cloud provider (Supabase, hosted in the United States) and stored encrypted:

Data	Purpose
Tab URLs and page titles	Synced across your devices
Workspace/folder names and structure	Synced across your devices
Account email address	To identify your account
Sync metadata (timestamps, device identifiers)	To resolve conflicts between devices

1.3 Payment data

A paid Pro tier is in development and is not currently on sale. When it launches, subscriptions will be processed by Lemon Squeezy as merchant of record. We will not see, store, or process your payment details — card numbers, billing addresses, and payment information are handled entirely by Lemon Squeezy under their own privacy policy.

2. Data We Never Collect

Never collected under any circumstances: your browsing history · cookies, session tokens or authentication credentials · passwords or form data · the content of web pages you visit (beyond page title and URL of tabs you explicitly save) · personal identity information (name, address, phone number) · location data · health, financial, or other sensitive category data.

3. How We Handle Your Data

3.1 Encryption

In transit: all communication with our servers uses HTTPS/TLS encryption.
At rest (cloud): cloud-synced data is stored in encrypted databases.
At rest (local): local data uses Chrome's built-in sandboxed storage, protected by the operating system's own encryption.

3.2 Data retention

Local data: retained until you uninstall the extension or clear it in settings. Uninstalling TabMod removes all locally stored data.
Cloud data: retained while your account is active. You can delete all cloud data at any time from within the extension settings. Deleted data is purged from our servers within 30 days.

3.3 Third-party services

Service	Purpose	Data shared
Supabase	Cloud database for optional sync	Tab URLs, titles, account email
Lemon Squeezy	Payment processing for Pro subscriptions (when launched)	Payment details — handled by Lemon Squeezy, not us

We do not use Google Analytics, Facebook Pixel, or any advertising or tracking SDKs.

4. Your Rights (GDPR & CCPA)

If you are located in the European Economic Area (EEA), the United Kingdom, or California, you have the following rights:

Right	How to exercise it
Access	Export your data from extension settings (JSON format)
Deletion	Use "Delete all cloud data" in extension settings, or email us
Data portability	Use the export function in settings to download your data
Object	Do not enable cloud sync — all data stays local by default
Rectification	Edit workspace and folder names directly in the extension

To exercise any of these rights, contact us at jdongxiao@gmail.com or open an issue on our GitHub repository. We respond within 30 days.

5. Data Security

Cloud data encrypted in transit and at rest
Supabase Row-Level Security ensures you can only access your own data
No tracking scripts, analytics cookies, or third-party embeds
Minimal permission model — the extension only requests permissions essential to its function (tabs, storage, alarms, contextMenus)
No background network requests at all unless you enable cloud sync

6. Children's Privacy

TabMod is not directed at children under 13 (or under 16 in the EEA). We do not knowingly collect data from children. If you believe a child has provided us with data, contact us and we will delete it.

7. Changes to This Policy

We will notify users of material changes via an in-extension notification on the next launch after the update, by updating the "Last updated" date on this page, and via a notice on our Chrome Web Store listing. We encourage you to review this policy periodically.
