A clearer health story,
with you in control.

The point of this is simple: you get a heads-up about trends in your own health before they slip past you. Here is how that happens.

Valeska compares your entries across days and weeks. It looks for things that are hard to hold in your head: a jump in how often a symptom shows up, a slow creep in severity, an "afternoons are worse" cluster, a brand-new symptom, a dip in keeping up with your Medications, or a win worth celebrating. Every finding shows the dates and numbers behind it, so you can see why it appeared.

Every pattern also carries how solid it is, said in plain words. A strong one is called out as standing out. A softer one says it is worth a look. One that could easily be luck says that too, along with how many comparisons it ran to get there. Only the days you actually logged count toward a pattern, so a week you skipped is never treated as a quiet week.

Once a pattern is found, supported devices can turn it into a sentence you can read at a glance, "Fatigue is up 48% this week, mostly in the afternoons" instead of raw figures. The summary is prepared on your device. Your notes, food names, and voice transcripts never leave it for an outside company to read.

The text appears sentence by sentence, so you are not left watching a blank screen while the summary is prepared. Valeska uses a few different formats for home cards, Symptoms detail, Visit Prep, and a day-at-a-glance summary, so each one fits the screen where it appears.

These limits exist so you can trust what you read: Valeska shows you what is happening, and the medical calls stay with you and your doctor.

It observes, you and your doctor decide. Valeska starts with patterns found in your own logs, puts those observations into plain language, and leaves every medical decision to the people in the room.

It never prescribes. Plain-language summaries are written not to suggest treatments, name causes, or tell you what to do. Every line is an observation. Valeska removes advice-like wording before you see it.

Each summary is checked before it reaches you. Advice phrasing is removed, web links are taken out, and the length is capped. So even if a stray link slips into a Symptoms note, it can never reach you as something clickable.

The writing is checked against your own numbers.Every on-device summary is labeled, so you always know what you are reading. Before it reaches you, the sentence is checked back against the dates and numbers in your logs. If the two do not line up, the wording is dropped and you get the plain summary of the numbers instead.

It asks you to agree first. Before plain-language summaries turn on, you accept a short note that says it straight: Valeska helps you organize your own health info; it is not a substitute for medical advice. The same note rides along on your Visit Prep export.

It works even on older devices. If your iPhone or iPad cannot prepare the richer summary on the device, Valeska uses simpler, ready-made wording. You still see the same dates, numbers, and useful changes. No one is locked out for having last year’s device.

The payoff here is peace of mind: your health history lives with you, not on someone else's server, and you hold the keys. Here is what that looks like in practice.

Kept on your device by default. Everything you log, Symptoms, Medications and doses, Nutrition, Water, Mood, Documents, and vitals, is saved in a private, locked store on your device. Syncing to the cloud is a separate feature you turn on yourself; it is off until you ask for it.

Locked when your device is locked. The store on your device is encrypted with a key held in your device's secure hardware and guarded by your passcode. Lose the device and the data can't be read. Delete the app and the key is destroyed with it.

Sharing stays scoped. If you invite a caregiver, the limits you set are enforced behind the scenes, not just by hiding buttons. A caregiver can't reach anything you didn't grant them, and when you turn off access it ends right away. If their app was closed at the time, their device clears what you took back as soon as it opens.

No health info in error reports. When something crashes, the report tells us what went wrong in the app. It deliberately leaves out the contents of your records, screenshots, and on-screen text. We can fix bugs without your private info ever tagging along.

Take it or delete it, anytime. Every part of the app can be exported, and Visit Prep makes a doctor-ready PDF on demand. Deleting your account wipes the copy on your device, the cloud copy if sync was ever on, and every stored key, one tap, no support ticket.

If you import lab results from Apple Health, they stay on your phone only. They are never uploaded to our servers, never included in pattern summaries, and never shown to a caregiver you share with. You can include them in your own Visit Prep and your own export, and nowhere else.

Results are shown exactly as reported by your lab. Talk with your care team about what they mean.

Medications you import from your providers behave just like the ones you add yourself. You review each one before it is added, imports never create duplicates, and a med that was stopped comes in as history with no new reminders. Because they are regular meds after that, they sync when you turn on cloud sync, and a caregiver you share medications with can see them.

Importing is free, and it is available in the United States.

Sync is here for when one device isn't enough, so your health info can keep up with how you actually live. It covers two situations: you have two devices (say an iPhone and an iPad) and want the same info on both, or a caregiver uses their own device to view or help with a shared profile. It is not there to mine your data. It is off by default and is part of the Pro plan.

A dose is kept as one record, not one per device. Mark it on your phone and it reads the same way on your iPad, and a dose you delete stays deleted.

If you drop back to the free plan, sync simply stops. Reinstalling without sync gives you a fresh start, with nothing pulled back from a server. Any info already in the cloud stays in your account until you choose to delete it, which you can do from Settings. You only ever see rows that are yours or that were shared with you.

We are not a hospital or insurer, and we don't pretend to be. HIPAA, the U.S. health-privacy law, may not bind a personal app like ours. But we built Valeska the way those rules would expect if it did: encrypted storage, access limited to what was granted, a record of sensitive changes, collecting only what's needed, and a delete button that truly deletes. People living with a chronic condition deserve that standard whether or not the law requires it.

What we do:

We lock all stored health info with a key unique to your device. We protect anything in transit between server and device. The sharing limits you set hold behind the scenes, not just in the app. We keep a log of every change a caregiver makes. We strip health info out of crash and performance reports. And we give you one-tap account deletion that clears your device, the cloud, and every stored key.

What we don't do:

We never sell, rent, or share your data, with anyone. We never send your health info to an outside processing or analytics service. We do not embed ad trackers. We do not replace your doctor’s advice. And we will not hold your data hostage if you stop paying.

Valeska is a tool. A doctor is a doctor. The app helps you see what you've been logging and bring a tidy summary to your next visit. It is not a diagnosis tool, not a clinical decision system, and not a replacement for professional care. Everything Valeska shows is an observation only; it never recommends, prescribes, or advises.

You accept this note before plain-language summaries turn on. The export PDFs carry it in the footer, and the Visit Prep header tells your doctor what they are looking at.

For emergencies, call 911 or your local emergency number. Don't open an app first.
