Privacy policy
Lock In is a Chrome extension that tracks how long you spend on websites and locks sites when you hit the daily limits you set. Your browsing history stays on your device. Lock In has no servers, no accounts and no analytics, and it never sends your data to the developer or anyone else.
What Lock In records
-
Website names and time spent. The hostname of each site you use (for example
youtube.com), how long you were actively on it, and when. Lock In does not record full addresses, page titles, page content, search terms or anything you type. - How long tabs were open on each site, as a daily total.
- Your settings: your daily limits, weekdays-only choices, preferences, and your lock-in password. The password itself is never stored, only a salted PBKDF2-SHA256 hash of it.
- Lock state for the day: whether a site is locked, extended or unlocked with your password.
In Incognito windows (only if you allow the extension there), Lock In records time only on sites you have put a limit on, so limits can't be dodged. Nothing else from Incognito is saved.
Where it is stored
Everything is stored in your browser's local extension storage (chrome.storage.local) on your
device. It is not uploaded anywhere.
Optional sync. If you turn on "Sync limits and settings" in Lock In's settings, your settings (limits,
weekdays-only choices, preferences, the password hash and any pending password reset) are copied to
chrome.storage.sync. Chrome sync then carries them to other computers signed in to your Chrome
profile, under
Google's privacy policy. Your browsing history is never
synced. Sync is off until you turn it on, and you can turn it off at any time.
What Lock In does not do
- It does not send any data to the developer or to any third party.
- It does not sell, share or transfer your data, and does not use it for advertising.
- It does not use analytics, tracking pixels, cookies or remote code.
- It does not use your data for anything except showing you your own usage and enforcing your own limits.
Why it needs its permissions
| Permission | Used for |
|---|---|
| Access to websites (http/https) | Showing the lock screen on a site you've limited, and knowing which site the active tab is on. |
| Tabs | Knowing which tab is in front, so only time you actually spend on a site counts. |
| Idle | Pausing the clock when you step away from the computer. |
| Storage, unlimited storage | Keeping your history and settings on your device. |
| Alarms | Saving time every 30 seconds and locking a site the moment its limit is reached. |
| Notifications | Warning you 5 minutes before a limit and when a site locks. |
| Scripting | Adding the lock screen to tabs that were already open when you installed Lock In. |
| Favicon | Showing site icons on the dashboard, read from Chrome's own local icon cache. |
Your control over your data
- See everything Lock In has recorded on its dashboard.
- Export it any time as CSV or JSON from Settings.
- Delete all tracking data from Settings.
- Set how long minute-by-minute detail is kept; older days are reduced to hourly totals.
- Uninstalling Lock In removes all of its local data from your browser.
Children
Lock In is a general-audience productivity tool. It does not knowingly collect information from anyone, including children, because it collects nothing off your device.
Changes
If this policy changes, the new version will be posted on this page with a new "last updated" date. If a future version ever needed to send data off your device, it would ask you first.
