Curfew privacy policy

Effective date: 16 October 2026

In short: Curfew keeps your settings, your session and a small weekly report in your browser, on your device. It has no server, no account, no analytics and no ads, and it sends no data to us. Its only network requests go to YouTube. The one exception is Settings sync, which is off until you turn it on: Chrome then keeps your settings in your Google account.

Who this covers

This policy covers the Curfew browser extension for Google Chrome and Microsoft Edge (“Curfew”), published by Mhase Technologies LLP (“we”). Curfew works only on youtube.com. It asks for a mode and a time before YouTube opens, ends the session when the time is up, and hides the parts of YouTube you choose.

What Curfew stores

Curfew saves the following in the browser’s local extension storage (chrome.storage.local). This storage stays in this browser profile on this device, and websites, YouTube included, can’t read it. It is not synced unless you turn on Settings sync (see “What Curfew sends”).

Settings

Your choices: what to hide in each mode and when no session is running, whether Shorts are hidden, whether the start screen appears, a pause end time, strictness, your three time choices and the last custom time you typed, which shortcuts the study page shows, whether the note field appears, whether Settings sync is on, the Strict cooldown you last picked, whether you have seen the note about Strict’s new rules, whether you have seen the welcome page, and two on/off marks for the one-line “what’s new” and rating notes (so each is shown once).

Kept until you change them, clear them, or remove Curfew.

Your weekly report

For each day in the last eight weeks: how many sessions you ran, the minutes you planned and the minutes you used, how many times you added time, how much of that was Study and how much Relax, and how many of the day’s sessions ended on time and how many ran past your plan. It holds no videos, no searches, no links, no notes and no times of day. It is shown in settings so you can see your week.

Days older than eight weeks are deleted as new ones are added. Kept until you use “Clear saved data” in settings or remove Curfew.

Notes in the popup

A few small numbers and yes/no values that decide when Curfew shows a one-line note in its popup: the day Curfew was first seen, how many sessions you have finished, whether the last one ended on time, whether you have answered or put off the request to rate Curfew (and how many sessions had finished when you put it off), which version’s “what’s new” note you have seen, and whether the short first-time line on the start screen is over. The rating request appears only in the popup, never on YouTube, and a small dot on the toolbar icon may show that it is waiting. These values hold nothing about what you watch, are never sent anywhere and are never synced.

Kept until you remove Curfew. “Clear saved data” leaves them, so a request you have answered is not asked again.

Your latest session

The mode you picked, the time you chose, when the session started and when it ends or ended, the minutes you added, how many times you added time or switched mode, the strictness the session started with, the cooldown you picked if it was Strict, and an internal counter that orders updates. If you take extra time to finish a video when time is up, it also keeps the number Chrome gives that browser tab and when the extra time started, its limit and when it ended. It never stores which video it was: Curfew remembers that only while the page is open. This lets every YouTube tab share one clock, lets the clock survive a browser restart, and keeps the short break or cooldown before your next session.

Kept until your next session replaces it, until you use “Clear saved data” in settings, or until you remove Curfew.

Your note (optional)

A short note you can type when you start a session, up to 80 characters. It appears on the clock.

Deleted when you end the session or start a new one. If the time runs out and you don’t end the session, the note is not deleted at a set time: it stays until Curfew next handles an action, such as starting a session, adding time or changing a setting, at least 30 minutes after the time ran out.

Curfew keeps no record of what you watch or which pages you visit. It does not store your searches, your YouTube account details or any password.

What Curfew sends

No data to us. Curfew has no server. It has no account or sign-in, and no analytics, tracking, advertising or crash reporting. It does not sell or share your data. Its only network requests are the ones to YouTube below, and Settings sync if you turn it on.
Settings sync, only if you turn it on. It is off by default. If you switch it on in settings, Chrome saves your settings (what to hide, strictness, your time choices, shortcuts and the note field) in your Google account and shares them with the other Chrome browsers you are signed in to. Curfew does not run this storage; Chrome and Google do, under Google’s own terms. Your sessions, your note, your weekly report and your pause are never synced. A change made on another browser that would give YouTube more room, such as turning sessions off, waits in settings until you apply it. To stop, switch sync off in settings. To remove the copy already in your Google account, use Chrome’s sync controls or reset your Chrome sync data.
Links, only when you click them. Settings and the popup have links to a feature-request form and a problem-report form, a link to Curfew’s reviews on the Chrome Web Store, and after you remove Curfew, Chrome may open a one-question survey page. They are pages run by Tally (tally.so), not by Curfew, and open in a new tab only when you click or after removal. Curfew adds its version number (for example 1.2.0) to the form links and nothing else about you. What you type into a form goes to Tally and to us, and we use it only to answer you and to improve Curfew.
One request to YouTube, when you ask for it. When you open “Your playlists” on the study page, Curfew asks youtube.com for your playlists page, from your browser and with your own YouTube sign-in, the same request YouTube makes when you open that page yourself. The list is shown on the page, never stored, and never sent anywhere else. If YouTube answers with a redirect, for example to a Google sign-in or consent page, Curfew does not follow it and shows a link to YouTube instead of a list. The playlist thumbnails load from YouTube’s image server (ytimg.com), as they do on YouTube, without telling it which page they appear on.
Your searches go to YouTube as usual. The search box on the study page opens YouTube’s own search results, exactly as YouTube’s search box does.

Why Curfew needs access to YouTube pages

Curfew asks for two permissions: storage, to save the items above (and, if you turn on Settings sync, to use Chrome’s sync storage), and access to www.youtube.com pages. It uses page access to show its start screen and clock, to pause the video when your time is up, and to hide the parts of YouTube you chose. It reads the page on your device to do this and copies nothing off your device. It keeps no page details.

How to see or delete your data

Open Curfew’s settings and use Clear saved data. This ends and deletes any session with its note, deletes your weekly report, turns Settings sync off and puts your settings back to their defaults. A few things stay: Strict, if you chose it (so clearing can’t be used to loosen it), your last cooldown choice, a mark that the welcome page is done, and the popup-note values above. During a session with Balanced or Strict, its short break or a Strict cooldown, clearing waits until that ends. Clearing does not remove a copy already saved in your Google account by Settings sync. Curfew also keeps one bare number that puts its saves in order; it says nothing about you or what you watched.
To delete everything, remove Curfew from your browser (in Chrome: chrome://extensions). The browser then deletes everything Curfew stored.

Limited Use

Curfew’s use of information it handles, including your playlist list, complies with the Chrome Web Store User Data Policy, including the Limited Use requirements. That information is used only to provide Curfew’s features on your device.

YouTube and Google

Your use of YouTube is covered by YouTube’s and Google’s own terms and privacy policies, not by this one. YouTube is a trademark of Google LLC. Use of this trademark is subject to Google Permissions. Curfew is not affiliated with or endorsed by Google.

Children

Curfew sends no personal information to us from anyone, including children. Anything typed into the optional note stays on the device. Curfew is a self-control tool for your own viewing, not parental control.

These web pages

The Curfew pages on gtoreflex.com load no scripts, fonts, cookies, analytics or third-party content. They are hosted by Vercel, which receives the ordinary request your browser makes to show a page, including your IP address.

Changes to this policy

If Curfew ever changes what it stores or sends, we will update this page before that version is released and change the effective date above.
