Only you hold the key
Records are encrypted in your browser with AES-256-GCM. Your password is stretched with Argon2id and never sent to us.
End-to-end encrypted health records
SECURECORDS tracks your bloodwork and vitals over time — and encrypts every value on your device before it's saved. Our servers store data they can't read. Not us, not our hosting provider, not anyone who breaks in.


The difference
Many online services encrypt data on their own servers, which means the company holds the keys. With SECURECORDS, the key that unlocks your records never leaves your hands.
Your browser encrypts it with a key only you can unlock — before anything is sent.
Our database holds scrambled data. Without your key it's unreadable — to us and to anyone who might break in.
Sign in on any device and your password unlocks your key on that device. We never receive your password.
The honest trade-off: because we never hold your key, we can't reset your password. You get a one-time recovery key at signup — keep it safe. Read the full security details →
Why SECURECORDS
Records are encrypted in your browser with AES-256-GCM. Your password is stretched with Argon2id and never sent to us.
All 50+ built-in markers and vitals, charts, Phenotypic Age and up to 500 readings — enough for years of routine bloodwork.
Download a complete copy of your records whenever you like, on every plan — including Free. Getting your own data out is never a paid feature.
No advertising, no third-party analytics or trackers in the app. We couldn't sell your health data if we wanted to — we can't read it.
SI or US units, sex-specific reference ranges, and the option to use your own lab's ranges. Compare lab visits side by side.
Values are shown against standard reference ranges — no risk scores, no scare tactics. A tracker, not a diagnoser.
A quick tour
Every marker gets a card with its trend line, latest value and status. Pin the ones you care about, filter to what's outside range, group by category or switch to a compact list.

Open any marker for its full history: a trend chart you can hover, your average over any period, where you sit in the reference range, and plain-language background on what it measures.

Each blood draw becomes a report card. Compare it with your previous visit — or any other — to see what changed and which markers moved into or out of range.

Build a clean PDF — summary table, charts, Phenotypic Age, BMI and life events — for your own records or to bring to your doctor. It's created on your device; nothing is uploaded.

SECURECORDS works in any modern browser, laid out for small screens — log a blood-pressure reading in seconds or check a trend in the waiting room.

Correct. Your browser encrypts every record before it's sent, using a key that's locked with your password. We store only the encrypted data and never receive your password or key. We can see your email address and how many records you have — not what they contain. How it works in detail.
Use the recovery key you saved at signup to set a new password. Because we never hold your key, we can't reset it for you — if you lose both your password and your recovery key, the data can't be recovered by anyone.
No. It's a personal tracker: it shows your values against standard clinical reference ranges and published research estimates such as Phenotypic Age. Please discuss your results with a qualified health professional.
More than 50 built-in markers across metabolic & kidney, lipids, liver, CBC, thyroid, inflammation and vitamins & minerals, plus vitals such as blood pressure, BMI, resting heart rate and home glucose. Anything else can be added as a custom biomarker. See the full list.
