Privacy
City lists and display preferences are stored locally in your browser (localStorage). Share links encode cities in the URL query string so recipients see the same view.
We do not require an account for core features and do not sell personal data. Avoid putting sensitive personal information in shared URLs.
We use Google Analytics (gtag.js) to understand aggregate traffic and improve the product. Google may process usage data according to its own policies.
How to use
Practical steps to stay in control of what you store and share.
Step 1
Use local preferences knowingly
When you reorder cities or change 12h/24h settings, those choices stay in your browser storage on this device.
Step 2
Review before sharing a link
Open Link to this view and confirm the URL only contains city IDs, home, date, and format — not names or private notes.
Step 3
Clear local data if needed
Remove site data for www.vclock.ink in your browser settings to reset saved cities and display toggles.
Step 4
Prefer generic city lists
For public posts, share common city combinations rather than links that might reveal a precise personal routine.
Use cases
When these privacy practices matter most.
Public social posts
Sharing a converter link in a public channel is fine for city grids; avoid embedding private meeting titles in the URL.
Shared work devices
On a borrowed laptop, clear site data after scheduling so the next user does not inherit your city list.
Client confidentiality
If a city list itself is sensitive, share times as copied text instead of a persistent bookmark URL.
Personal travel planning
Family city lists stored locally are convenient; treat share links like any other URL you would paste into chat.
Examples
What is stored where.
Browser localStorage example
A typical save includes city IDs, home city id, hour format, and display toggles such as abbreviations — not your email or calendar.
Share URL example
A link may look like www.vclock.ink/?cities=…&home=…&date=…&fmt=12h. Recipients only see the converter state encoded there.
Copied meeting text example
Copy from Meeting window produces city names, local times, and www.vclock.ink — useful for email without exposing other browser data.
