I Built a Symptom Tracker That Respects Your Privacy

INTRO

You finally book a doctor's appointment after weeks of feeling off.

The doctor asks: "When did this start?"

And your mind goes blank.

That moment is exactly why I built Symply — a private, no-account

symptom tracker that turns your daily health logs into a clean

doctor-ready PDF report.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

THE PROBLEM

Most people have no record of how they felt last Tuesday. Or the

Tuesday before that. We remember the dramatic moments — but the

subtle patterns? The fatigue that builds slowly, the headaches

that spike every afternoon, the nausea that comes and goes?

Those patterns are exactly what doctors need. And we have no way

to show them.

Existing health apps are either too complex, require an account,

or store sensitive data on a cloud server you don't control.

I wanted something simpler. Something that respects your privacy

from day one.

INTRODUCING SYMPLY

Symply is a micro-app built around one belief:

Your health data belongs to you — and only you.

No signup. No account. No data leaving your device.

Everything lives in your browser's local storage.

THREE THINGS SYMPLY DOES REALLY WELL

01 — Log a symptom in 15 seconds

Type the name, tap the severity, hit save. No categories,

no mandatory fields, no friction. Just log and go.

02 — See your patterns clearly

A visual timeline shows every entry in order. A frequency

chart highlights which symptoms keep coming back. Summary

cards show your average severity at a glance.

03 — Export a PDF your doctor will love

Before any appointment, tap Export. Symply generates a clean,

formatted "Patient Symptom Report" entirely in your browser —

no upload, no server, just a ready-to-share PDF.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

WHY PRIVACY-FIRST?

Health data is the most sensitive kind of personal data there is.

The moment an app stores your symptoms on a server, questions

arise. Who has access? Can it be breached? Is it sold?

Symply avoids all of that by design. There is no server. There

is no database. Your symptoms never leave your phone or browser.

That's not a workaround — it's the whole point.
