In a world where most free tools make money from your data, Chronological Age Calculator takes a completely different approach:
We do not collect your personal data. We do not store it. We do not sell it. We do not want it.
Speech therapists, school psychologists, and pediatric professionals handle sensitive information every day — children’s birth dates, assessment records, clinical data. The last thing you need is a tool that treats that information as a commodity. So we designed Chronological Age Calculator to work entirely within your browser. What you enter never leaves your device.
This is not a marketing claim. It is how the technology actually works.
What Happens When You Use the Calculator
When you enter a date of birth and test date into Chronological Age Calculator — and optionally a prematurity adjustment — that data is processed entirely within your own browser using JavaScript.
It is never transmitted to our servers. Never stored in a database. Never logged or recorded in any way. When you close the page, the data is gone permanently — because it was never ours to begin with.
Anonymous Analytics — What We Do Collect
To improve Chronological Age Calculator, we collect basic fully anonymized analytics — including general location at country or city level, device type, browser type, and pages visited.
This data is aggregated and anonymous. It tells us things like “500 professionals in Australia used the calculator today” — not who they were or what dates they entered. It helps us improve the tool. It cannot identify you personally.
Cookies
Chronological Age Calculator may use minimal non-intrusive cookies to support basic website functionality. We do not use advertising cookies, tracking pixels, remarketing tools, or behavioral profiling of any kind. You can disable cookies in your browser at any time without affecting the calculator’s functionality.
Children’s Data — Extra Care, Always
Chronological Age Calculator is used daily to calculate the age of children for ASQ screenings, Brigance assessments, Pearson evaluations, and speech therapy assessments. We take this responsibility extremely seriously.
We collect zero personal information about children. No names. No birth dates stored on servers. No identifying data of any kind. Chronological Age Calculator is fully compliant with COPPA and applicable international children’s data protection regulations including GDPR provisions for minors.
Third-Party Services
Chronological Age Calculator may use Google Analytics for anonymous traffic analysis. We are not affiliated with Pearson, ASQ, Brigance, LAUSD, Peabody, Gesell, Super Duper, or Home Speech Home. We do not share any data with any third-party assessment organization.
Policy Updates
We may update this Privacy Policy periodically. We will never make changes that reduce your privacy protections without clear notice. The date at the top always reflects the latest revision.
You deserve a tool that protects your privacy with the same care you give your patients and students. That is our promise — today, tomorrow, and always.📧 ashbalch26@gmail.com 🌐 smartagecalc.com/contact-us .Chronological Age Calculator — Private by Design. Free by Choice.
