Privacy Policy

Effective date: July 25, 2026

ZaynClock is designed to work without an account. This policy explains what is stored in your browser, what may be sent to third-party services, and what choices you have.

Information stored on your device

ZaynClock uses browser local storage to remember settings and data you choose to create, including clock preferences, time zone, theme, alarms, calendar events, todo items, pinned world clocks, study-session history and an optional custom alert sound. This information remains in your browser unless you clear site data or your browser removes it. It is not synchronized to a ZaynClock account.

Location and weather

The weather feature can use your browser's geolocation permission. ZaynClock requests location only after you choose to use your location. When you approve, your coordinates are sent directly from your browser to Open-Meteo services to retrieve weather, air-quality and place-name results. Open-Meteo and your network provider may receive technical information such as your IP address. ZaynClock does not store your precise coordinates on its own servers.

Browser notifications

Alarm, timer, Pomodoro and study tools may ask for notification permission after you interact with them. Notification permission is controlled by your browser or operating system and can be revoked in browser settings.

Advertising and cookies

If Google AdSense is enabled, Google and its partners may use cookies, device identifiers or similar technologies to deliver, measure and limit advertisements. Where required, a consent message should appear before personalized advertising technologies are used. You can review or change advertising choices through the consent message when available and through Google's advertising controls.

ZaynClock does not currently load a separate analytics service in this codebase. If analytics is added later, this policy will be updated before that service is enabled.

Server and security logs

Our hosting and security providers may automatically process basic request information, such as IP address, browser type, requested URL, timestamps and error or security events. These logs are used to operate, protect and troubleshoot the website and are retained according to the provider's operational policies.

Children's privacy

ZaynClock is a general-audience utility and is not designed to collect personal information from children. We do not knowingly provide account registration or ask children to submit personal profiles.

Your choices

You can clear ZaynClock's locally stored information through your browser's site-data controls, deny or revoke location and notification permissions, and use advertising or consent controls where shown. Blocking optional features may prevent weather, alerts or personalized advertising from working.

External services and links

Third-party services operate under their own privacy policies. ZaynClock is not responsible for the privacy practices of external websites reached through links or third-party requests.

Changes to this policy

We may update this policy when features or service providers change. The effective date at the top will be revised when a material update is published.
