PageTimer Privacy Policy

Last updated: June 18, 2026

PageTimer is a Chrome extension that tracks how much active foreground time you spend on each website. This policy explains exactly what data is collected, what is not, and how any collected data is used.

Data stored on your device

All browsing data (the list of websites you visit and the time you spend on them) is stored exclusively in chrome.storage.local on your own device. This data is never transmitted anywhere. It is retained for up to 35 days and then automatically deleted.

The following is stored locally and never leaves your device:

Per-site active time (in milliseconds), keyed by hostname only (e.g. example.com)
Time limits you configure for specific sites
The list of currently blocked sites
A randomly generated device ID (UUID), see below

Anonymous usage analytics

PageTimer collects a small number of anonymous, non-personal events to understand how the extension is used and to guide improvements. These events are sent to PostHog, a third-party analytics platform.

What IS collected

Event	Properties
`extension_installed`	none
`popup_session`	`duration_seconds`: how long the popup was open
`period_changed`	`days`: which tab (1 / 7 / 30) was selected
`limit_saved`	`action`: `notify` or `block`
`limit_removed`	none
`limit_triggered`	`action`: `notify` or `block`
`site_unblocked`	none
`feedback_submitted`	`category` and `message`: only the text you choose to type and send via the feedback form

Each event is associated with a device ID: a randomly generated UUID created when the extension is first installed. It has no connection to your Google account, identity, or any personal information. It is used solely to count unique installs versus total events.

What is NOT collected

Any website hostnames, URLs, or browsing history
IP addresses or geographic location ($geoip_disable: true is always sent)
Personal information of any kind
Browser fingerprint, screen resolution, or device specifications
Time-on-site data or any usage statistics from your local storage

Third-party services

Analytics events are sent to PostHog (US region, us.i.posthog.com). PostHog's own privacy policy is available at posthog.com/privacy. No other third-party services receive any data.

Permissions used

Permission	Why it's needed
`tabs`	To detect which tab is active and read its URL so time can be attributed to the correct hostname. URLs are never stored or transmitted.
`storage`	To persist time-tracking data, time limits, and the device ID locally on your device.
`alarms`	To flush in-progress session data to storage every 30 seconds and check time limits, even if the service worker restarts.
`notifications`	To display a desktop notification when a time limit you configured is reached (only when you choose the "notify" limit type).

Data retention and deletion

Local time-tracking data is automatically pruned to the last 35 days. You can remove all data at any time by uninstalling the extension, which clears chrome.storage.local for this extension.

Anonymous analytics events stored by PostHog are retained according to PostHog's standard data retention policy.

Children's privacy

PageTimer does not knowingly collect data from children under 13. The extension collects only anonymous, non-personal usage events and no information that could identify any individual.

Changes to this policy

If the data practices described here change materially, this page will be updated and the "Last updated" date will reflect the revision.
