Privacy Policy

Effective July 15, 2026

The short version. BoomClock has no accounts and no user database. The timers you save, the ones you create, and your display settings are stored on your own device and are never sent to us. We don't run analytics. We don't sell data about you, because we don't have any. The one thing worth reading below is the advertising section, because ads involve companies that are not us.

What we store on your device

BoomClock uses your browser's local storage to remember your choices between visits. This data lives in your browser, on your device. It is not transmitted to any BoomClock server, because BoomClock does not have one: the site is a set of static files.

Specifically, we store:

You can delete all of it at any time by clearing site data for boomclock.com in your browser settings. There is no "delete my account" request to send us, because there is no account. Clearing your browser is the whole process, and it is irreversible: we hold no copy to restore from.

What we don't do

If you email us a timer suggestion using the "Suggest to BoomClock" form, that opens your own email client and sends a message to us directly. We then have whatever you chose to put in that email, including your email address. We use it to consider your suggestion and nothing else.

Fonts and other third parties

BoomClock loads its typefaces (Bangers and Roboto Mono) from Google Fonts. To deliver those fonts, your browser makes a request to Google's servers, which means Google receives your IP address and standard request information. We do not control that, and we do not receive anything from it. If this concerns you, Google's handling of Fonts requests is described in the Google Privacy Policy.

Advertising

When ads are shown on BoomClock, they are served by Google AdSense. This is what pays for the site. It also means Google and its partners are involved in your visit, and you should know how.

If you are in the European Economic Area, the United Kingdom, or Switzerland, you will be asked for consent before any personalised advertising cookies are set, and you can decline. Declining does not lock you out of anything on BoomClock: every timer works the same either way.

Your rights

Data protection law in the EEA, the UK, and some other places gives you rights to access, correct, export, and delete personal data held about you. In BoomClock's case the honest answer is that we hold none, so there is nothing for us to hand over or erase. The data that exists is in your browser and under your control.

Rights relating to data held by Google as an advertising provider must be exercised with Google, through the links in the advertising section above.

Children

BoomClock is not directed at children under 13, and we do not knowingly collect personal information from anyone. If you believe a child has sent us personal information by email, contact us and we will delete it.

Changes to this policy

If we change how any of this works, we will update this page and move the effective date at the top. Meaningful changes, such as adding analytics or a new third party, will be described here rather than quietly folded in.
