A timer with no ads — no banners, no video pre-rolls, no popups, no cookie wall, no newsletter prompt, and no account. Set a duration and start. Nothing will load in late, shift the layout, flash in the corner, or ask you for an email while your session runs.
Timer searches carry enormous volume, and a visitor who leaves a tab open for 25 minutes is unusually valuable — one session generates repeated ad impressions with no additional effort. That economics is why so many timer sites are advertising businesses with a clock attached, and why the countdown is frequently the smallest element on the screen.
Polytimer avoids this by being cheap to run. It is a static site: pre-built HTML served from a CDN, with the timer running entirely in your browser. No database, no server processing your sessions, effectively no per-user cost — and no user data to monetise even if we wanted to.
A timer is not a page you read and leave. You set it precisely because you are trying to concentrate on something else, and then you leave it on screen for the whole session. Any animated banner or blinking badge sitting next to the countdown is in your peripheral vision for the entire block of work you were trying to protect. An ad-free timer is not a nicety here — it is the actual function of the tool.

Your timers never leave your device. Durations, laps, Pomodoro sessions, theme, and alarm choice are all held in your browser's local storage — there is no account to attach them to and no server storing them. Because a service worker caches the app on your first visit, the timer also runs with the network switched off entirely. Full detail is in the privacy policy.
Yes. Polytimer serves no ads at all — no banners, video pre-rolls, interstitials, affiliate blocks, or sponsored presets. Nothing to close before you start and nothing that loads late and pushes the countdown down the page mid-session.

No. No account, no email prompt, no trial, no consent wall. Theme, alarm sound, and last-used duration are stored in your own browser's local storage and stay on your device.
Press Fullscreen — navigation, tabs, page content, and browser chrome all disappear, leaving only the countdown. If you need to keep working, use Picture-in-Picture: a small always-on-top window that floats over your other applications.
Closing the tab stops the timer, but you do not need to keep it in view. A background Web Worker keeps time accurately and the alarm still fires when the tab is in the background, the window is minimised, or the screen is off.
