Privacy, by design.
You can calculate without a name, email or account. The baby-age tool processes entered dates in your browser.
Your dates belong with you.
- No baby’s name needed
- No account to create
- No date uploads
Calculator dates are not submitted
Birth, comparison and due dates, as well as gestational age, are used by local date functions. Calculating does not send these values to an API, add them to a URL or create a cloud record. The tool does not emit analytics events containing these inputs.
The page itself must still be requested from the hosting service. Its basic request information can include an IP address, URL, device headers and request timing. That is separate from the calculator’s date inputs.
Saving is optional and device-local
Dates are not saved by the calculator by default. Choosing Save on this device stores the calculator inputs in this browser’s localStorage. Choosing Clear saved dates removes that saved record. Reset clears the visible form; use the separate saved-data control to remove storage too.
Other people using the same browser profile can access saved values. Private browsing or browser cleanup may remove them. There is no account sync or cloud backup.
Copying and printing are your choice
Copy result puts the displayed result and its dates on your device clipboard. Printing opens your browser’s print dialog; a printer, operating system or saved PDF may keep a copy. Check what is included before sharing either output.
No date-filled sharing link is generated by this version of the tool. If you manually send a screenshot or printed result, its recipient can read any dates visible in it.
External resources and feedback
Following an external reference leaves this site. The destination has its own privacy practices and may receive normal browser request information. We do not attach calculator dates to those links.
The contact page prepares feedback locally and does not submit it. Avoid adding personal data to that note. This tool is for general information and does not assess a child’s health.
Does clearing saved dates undo copying or printing?
No. Clear saved dates removes the calculator record in this browser’s localStorage. It does not remove text already copied to a clipboard, a screenshot, a printed page or a PDF saved elsewhere. Reset only clears the current inputs.
Review any output before you give it to someone else. Anyone who receives a copied or printed result can read the dates included in that result.
