Calluna Today screen — dose streak ring and the day's medications

Private by design

Nothing leaves your phone unless you carry it out yourself.

No servers to trust, because there aren't any. Calluna runs entirely on your device.

No account, ever

No sign-up, no analytics, no cloud. Just you and your data, on your phone.

Lock-screen safe

Reminders say only “Evening check-in” — never the medication. Discreet by default.

Encrypted backups

Passphrase-protected files you control. There’s no recovery — it’s yours alone.

Meds & doses

Doses, on your schedule.

Two-tap logging, streaks that keep you going, and supply that warns you before you run out — not after.

Daily, every-N-days, or weekly schedules
Supply rings that count down your refills
Med search with autocomplete, fully offline

Calluna medication list with supply rings

Lab work

Labs, tracked toward your targets.

Log estradiol, testosterone, and more against your own reference bands. Each analyte becomes a trend over time — Calluna shows you the shape of your levels and never judges a single number.

Your own reference low and high, per analyte
Every result charted as a trend line
Information, never a verdict

Discreet reminders

A nudge only you can read.

Every reminder is deliberately vague on the lock screen. It says “Evening check-in” and nothing else — your medication is never named where someone could glance at it.

Mood & energy

How you feel, in ten seconds.

An axolotl that wears your mood. Tap a face from Low to Great, set your energy, flag what’s notable — good sleep, bloating, energized — and leave a note for future you. Ten seconds, and like everything in Calluna, it never leaves the device.

Five expressive axolotl moods, Low to Great

An optional private note, just for you

Calluna mood check-in — an axolotl wearing your mood, with energy and symptom tags

Body measurements

Watch yourself change, at your own pace.

A body map you actually tap — pick your waist, chest, hips, and Calluna shows you exactly where to measure. Every number becomes a gentle trend over time. No goals, no comparisons, no “ideal” — just your own change, kept on your device.

Every measurement charted as a trend over time
No targets, no judgment — your pace, your numbers

Trends, not scores

Everything you log becomes a pattern you can see.

Calluna never grades you. It shows you the shape of your own change over time — and quietly surfaces what tends to move it.

Why this exists

Your transition is nobody's business but yours.

Right now hundreds of bills are moving through statehouses aimed at trans healthcare, IDs, and the right to exist on a form — with federal directives pushing the same from the top. The count changes weekly; the trackers below keep the running tally. When your hormones, your labs, your name change sit on some company's server, they're one breach, one subpoena, one policy shift away from people who'd use them against you.

Calluna doesn't have a server. No account to leak, no cloud to raid, nothing to hand over — because there's no “we” holding your data. It lives encrypted on your phone and stays there. Not a feature on the side. The whole point.

Made by us, for us — because we're the ones tired of trusting our most sensitive records to companies that were never built to protect us. No investors, no growth metrics. A tool that does its job and shuts up.
