Last updated: May 13, 2026

Focusly is a Chrome extension that helps you stay focused by blocking distracting websites, tracking browsing time, and running focus rituals (Pomodoro-style timers). This policy explains exactly what data we collect, how we use it, where it is stored, and who we share it with.

1. Data We Collect

1.1 Account Data (optional – only if you sign in)

If you create a Focusly account or sign in with Google, we collect:

You can use Focusly without an account. Account creation is optional and only required for cross-device sync or premium features.

1.2 Block List and Settings Data

The extension stores the configuration you create, including:

This data is stored locally in your browser (chrome.storage.local and chrome.storage.sync) and, if you are signed in, synced to our cloud database (Firebase Firestore) so your settings are available across devices.

1.3 Usage Statistics

The extension tracks how much time you spend on blocked or monitored sites. Specifically:

Usage data is stored locally in your browser. If you are signed in, aggregated daily usage totals (seconds per domain, date) are also synced to Firestore to allow cross-device consistency. We do not collect, transmit, or store the specific URLs or page titles of websites you visit — only the domain names of sites that are in your block list.

1.4 YouTube Creator Search Data

When you use the "Block YouTube Creator" feature and search for a channel handle (e.g. @channelname), the extension makes a network request to YouTube's public website (https://www.youtube.com/) to retrieve the channel's public name and profile thumbnail. This request:

We do not store YouTube search queries on our servers. YouTube's own privacy policy governs YouTube's handling of this request.

1.5 Payment Data

Premium subscriptions are processed by Stripe via our Firebase Cloud Functions backend. When you upgrade:

1.6 Technical and Diagnostic Data

The extension does not automatically collect crash reports, telemetry, or analytics. We do not use any third-party analytics SDK (e.g. Google Analytics) inside the extension. Console logs are written locally to your browser's developer tools only.

2. How We Use Your Data

Data Purpose
Email address, UID Account authentication; sending password reset emails; associating your data with your account in Firestore.
Block list and settings Enforcing website blocks; displaying your configuration in the dashboard; syncing across devices (if signed in).
Daily usage statistics Enforcing daily time limits; displaying usage charts in the analytics dashboard; syncing across devices (if signed in).
YouTube creator handle / thumbnail Identifying the correct YouTube channel to block; displaying the channel avatar in the block list UI.
Subscription status Unlocking premium features; verifying your plan in the extension UI.
Language preference, locale Displaying the extension in your preferred language (English, Polish, Spanish).

3. Data Storage

3.1 Local Storage (in your browser)

The majority of Focusly's data lives entirely on your device in Chrome's built-in storage APIs:

Data in chrome.storage.local stays on your device and is never transmitted to our servers unless you are signed into a Focusly account (see Section 3.2).

3.2 Cloud Storage (Firebase Firestore) – signed-in users only

If you create a Focusly account and sign in, the following data is stored in Google Firebase Firestore under your unique user ID:

Firestore data is stored on Google's servers in the us-central1 region (United States). Google's data processing terms apply: firebase.google.com/support/privacy.

Data is retained for as long as your account is active. If you delete your account, all associated Firestore documents are deleted.

3.3 Data Retention

4. Data Sharing

We do not sell, rent, or trade your personal data. We share data only with the following service providers, and only to the extent necessary to operate the extension:

Third Party Data Shared Purpose Privacy Policy

YouTube (Google) HTTP request for public channel pages (no personal data sent) Fetching public creator name and thumbnail when you add a YouTube Creator block policies.google.com/privacy
