A private symptom tracker, by design.
Your health is nobody's business but yours. Valeska keeps what you log on your iPhone, runs its pattern spotting right on your device, and never sells your data. It is free to start, and you do not need an account to begin.
Your logs stay on your phone
Everything you track is saved in a locked store on your iPhone. Nothing is sent anywhere unless you turn on sync yourself.
The AI runs on your device
Valeska spots patterns using Apple's on-device models. Your notes, food names, and voice never go to an outside service to be read.
We never sell your data
No ad trackers, no selling, no renting, no sharing. We do not hand your health info to outside AI or analytics. Not now, not later.
Take it or delete it, anytime
Export your data whenever you like, or delete all of it, your phone, the cloud copy if you ever synced, and the keys, in one tap.
Why we built it this way.
Most health apps work the other way around. Your symptoms, periods, and moods go up to a company's servers, where they can be studied, shared, or sold. Mozilla's Privacy Not Included guide has reviewed a long list of health and period apps and found that a lot of them collect and share more than people expect. We did not want to be one of them.
So Valeska keeps your data with you by default. The app does its thinking on your phone, not in someone else's data center. You can read the full details, down to how the store is encrypted and locked, on thehow it works and your privacy page.

If you ever want to sync.
Want your info on an iPhone and an iPad, or to let a caregiver help? You can turn on sync. It is off until you ask, it is part of the Pro plan, and it is built so only you and the people you choose can see your rows. Drop back to the free plan and sync simply stops.
When you invite a caregiver, you pick exactly what they see, and the limits you set are enforced down at the data layer, not just in the buttons. Turn off their access and it ends right away.
Private, whatever you live with.
Valeska keeps your logs private the same way for every condition, from MS and migraine to lupus, IBS, and ones the textbooks barely name.
