Cookie policy

Cookies are small pieces of data that a website asks a browser to retain. Similar functions can use local storage, session storage, or other device identifiers. On this site they may keep a preference, support a running tool, maintain security, remember a consent choice, measure aggregate traffic, or help diagnose an error. Some storage disappears when the browser closes; other items remain until expiry or deletion.

Strictly necessary storage supports functions that cannot sensibly operate without it, including security, load distribution, consent records, and requested settings. Preference storage can remember choices such as presentation or a recently selected option. Measurement storage can show which pages are used and whether errors occur. Any third-party feature may set or read its own storage under that provider's terms.

A timer, alarm, stopwatch, or selected date may use browser state. Do not treat that state as a durable record. Private browsing, storage limits, browser updates, power loss, automatic cleanup, or manual deletion can remove it. Keep the relevant tab open and use an independent cue where losing a countdown could affect cooking, medication, safety, work, school pickup, or a connection.

Visitors can control cookies through the consent choices offered on the site and through browser settings. A browser may block all cookies, block third-party cookies, delete selected site data, or clear information on exit. These choices can reset preferences, sign out an active session if one exists, reduce diagnostic information, or prevent part of a tool from behaving as expected.

Browser signals and extensions do not all operate in the same way, and a setting on one device does not automatically carry to another. Review controls on each browser used. Clearing data while a stopwatch or countdown is active may discard its state. Audio permissions, notifications, and power-saving controls are separate from cookies and need their own checks.

Technical records may use Coordinated Universal Time while the visible local clock moves between UTC+12 and UTC+13. Consequently, an entry made around midnight, the September or April clock change, or an overseas interaction may carry a different date in a log. This is a timekeeping difference rather than necessarily evidence of a misplaced cookie.

Storage durations depend on purpose. Session items are generally shorter lived; preference, consent, security, and measurement records may remain longer. Data can be retained for a reasonable period to investigate abuse, maintain records, or meet legal duties even after browser storage is cleared. The privacy notice explains wider information handling and contact options. Read the visible labels and retain a copy of any consequential input and result. Check the current page and device settings before relying on an output. Where the law provides non-excludable protections, those protections continue to apply.
