This website (worldtimes.zone, “World Times Zone”) is operated by Arbitrary Ventures Ltd (“we”, “us”), which is the controller of personal data for the purposes of the UK GDPR.

2. What data we collect
Usage and technical data
When you use the site we may collect information such as pages viewed, interactions (e.g. timezone searches/selection), approximate location (derived from IP), device and browser information, and identifiers stored in cookies or local storage.
Local storage on your device
We use your browser’s local storage to remember recent locations and your active timezones so the planner works smoothly on your device.
Messages you send us
If you email us, we will process the contents of your message and your contact details.
We do not ask you to create an account, and we do not intentionally collect special category data.
3. How we use your data (and lawful basis)
- Provide the service (e.g. saving your preferences locally, keeping the site reliable) — our legitimate interests and, where applicable, performance of a contract when you use the service.
- Improve the product (e.g. understanding feature usage and performance) — our legitimate interests.
- Analytics cookies / similar technologies — where required by UK law, we rely on your consent for non-essential cookies and similar technologies.
- Respond to enquiries — our legitimate interests and/or performance of a contract.
4. Cookies and similar technologies
We may use cookies and local storage for essential functionality and analytics. You can control cookies through your browser settings, including blocking or deleting cookies. If you block cookies, some functionality may not work as intended.
5. Sharing and processors
We use service providers (processors) to operate the site and measure usage. This includes our hosting and infrastructure providers and our analytics provider (PostHog). We share only what is needed for them to provide their services.
6. International transfers
Some of our service providers may process data outside the UK. Where this happens, we take steps to ensure appropriate safeguards are in place (such as standard contractual clauses) and that transfers comply with UK GDPR.
7. Data retention
We keep personal data only for as long as necessary for the purposes described above. Where analytics data is collected, we typically retain it for up to 24 months (unless we need it for longer to resolve issues or meet legal obligations).
8. Your rights
Under UK GDPR, you may have rights including access, rectification, erasure, restriction, objection, and data portability. You can also withdraw consent at any time where we rely on consent.
To exercise your rights, contact us at matt@mattneary.co.
9. Complaints
If you’re unhappy with how we handle your data, you can contact us first. You also have the right to complain to the UK Information Commissioner’s Office (ICO): ico.org.uk.
