Privacy

This version has no accounts, payment collection or contact forms. It shows ads from Google AdSense and counts visits with Cloudflare Web Analytics. Your timers and settings stay in your browser; the app does not send them to us or to Google.

Local preferences

Sound choice, volume, light or dark theme and custom Pomodoro lengths are stored in localStorage when your browser allows it. These preferences can be shared between tabs and future visits. If you enter a date on the birthday countdown, that date is saved in localStorage (ot-birthday-v1) on your device only, so the countdown is still there next time. It is never sent to us. Change or delete it on the page, or clear the site data in your browser.

Your active timer

Each page uses this tab’s sessionStorage to save the chosen duration, end time, paused time, completion state and any classroom label or progress-ring choice. This supports recovery after reloading. Tabs do not write to each other’s active timers. A duplicated tab may initially receive a copy from the browser, but a fresh page navigation starts with its page default.

If storage is blocked, timing still works for the current visit. Reload recovery and preference saving may be unavailable.

Offline files

A service worker caches the site’s pages, scripts, styles and icons on your device. Remove these files and saved preferences through your browser’s site-data settings. An installed app is not an alarm service while closed.

Advertising (Google AdSense)

Online Timer is free and paid for by ads served by Google AdSense. Google and its partners may use cookies and similar technology to show ads, limit how often you see them, measure how they perform and prevent fraud. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites.

Personalised ads are shown only with your consent where the law requires it. Visitors in the European Economic Area, the UK and Switzerland see a consent message from Google, a Google-certified consent management platform, where you can accept, refuse or manage your choices, and change them later. Without consent, Google may still show non-personalised or limited ads, which can use cookies or similar technology for frequency capping, aggregated reporting and fraud prevention.

Read How Google uses information from sites or apps that use our services. You can turn off personalised ads from Google in Ads Settings.

You can also opt out of personalised advertising from many other third-party vendors at www.aboutads.info/choices or, in Europe, at www.youronlinechoices.eu. Turning off personalised ads does not remove all ads; you will still see ads, but they will not be based on your earlier activity.

Ads are never placed inside the timer card or on its buttons. The teacher page is kept free of ads. The embeddable timer at /embed/ loads no analytics and no third-party scripts from Online Timer.

Visitor statistics

We use Cloudflare Web Analytics, which counts visits in aggregate. It shows us totals such as page views, popular pages, referring sites, browsers, countries and page-load speed. It is not loaded in the embeddable timer at /embed/.

Hosting

The site is hosted on Cloudflare Pages, and network requests pass through Cloudflare. Cloudflare may also run automated security checks, including a small script, to protect the site against bots and abuse. Information such as IP addresses and browser request details may be processed to serve and protect the site. Timer settings are not intentionally sent by this app to a server.

Your choices and rights

You can change or withdraw your ad consent at any time through the Google consent message (where shown), turn off personalised ads in Google’s Ads Settings, and delete locally stored settings and offline files through your browser’s site-data settings. If you are in the EU/EEA or the UK, you have the right to request access to, correction or deletion of personal data we hold about you, and to object to processing. We do not collect accounts or contact forms, so we usually hold no personal data about visitors other than emails you send us. Personalised ads and advertising cookies are based on your consent; hosting, security and visitor counts on our legitimate interest in a working, secure site. You can also complain to a data protection authority; in Sweden this is the Swedish Authority for Privacy Protection (IMY).

Who is Online Timer for, and what about children?

Online Timer is a general-audience site for anyone who needs a timer, at home, at work or in class. It is not directed at children under 13. Pupils may see it on a classroom screen, but there are no accounts and no forms, so we do not ask anyone for a name, email address or other details, and we do not knowingly collect personal information from children. If you think a child has sent us personal information, for example by email, write to info@onlinetimer.app and we will delete it.

Frequently asked questions

Does Online Timer use cookies?

Yes, through Google AdSense on pages with ads. In the EEA, the UK and Switzerland you are asked first. The timer itself does not need cookies; it uses your browser's storage for settings and the running timer.

Can I use the timer without personalised ads?

Yes. Refuse personalised ads in the consent message, or turn them off in Google Ads Settings. You will still see ads on some pages, but they will not be based on your earlier activity.
