Clock and timer information
Clock84 reads your device's local time and uses your browser to calculate countdowns, stopwatch times and world-city time displays. There is no login for these tools.
Clock84 is primarily a browser-based utility. We aim to make its data use understandable, without requiring an account for the time tools.
Clock84 reads your device's local time and uses your browser to calculate countdowns, stopwatch times and world-city time displays. There is no login for these tools.
Some preferences, selected world cities and alarms are stored locally in your browser using localStorage. You can remove this data through your browser's site-data controls.
Alarm sounds and desktop notifications require the browser and device to allow them. Clock84 does not promise alerts when the tab is closed or the device is sleeping.
If you submit the contact form, your name, email address and message are transmitted to the website server and forwarded to the configured Arcana Synthetica mailbox for handling your inquiry. Do not include sensitive information you do not want sent by email.
As with other websites, your hosting provider may keep technical server access and security logs, such as IP addresses and request timestamps. Server-side retention depends on hosting configuration.
NotaDirect, Babyphone.online, DropToPhone and Arcana Profile are separate websites, each with its own features and privacy information. Their privacy practices are not automatically the same as Clock84's.
