Symptio — Privacy Policy

Our commitment: Symptio is designed with privacy at its core. Your health data stays on your device and in your personal iCloud account. We don't collect, sell, or share your personal information. We don't run ads. We don't have servers. The only information that leaves your device for us is an optional, anonymous daily count of which features were used — never any health data (see Anonymous Usage Statistics).

What Data Does Symptio Store?

Symptio stores the following information locally on your device:

Symptom records — symptom name, severity level, date and time
Triggers — optional trigger tags you associate with symptoms
Notes — optional free-text notes for each record
Photos — optional photos attached to symptom records (e.g. skin conditions)
Medications — medication names and dosage information you enter
Family profiles — names and profiles for family members you track
App preferences — notification settings, display preferences

All of this data is created by you and stored on your device.

On-Device Analysis

Symptio's Smart Insights feature analyzes your symptom patterns entirely on your device. No data is sent to any external server or AI service for processing.

Family Profiles

Family profile data is created and managed solely by the primary user. Family members are not required to create accounts or provide consent through the app.

HealthKit Integration

Symptio can optionally read data from Apple HealthKit to help you correlate symptoms with health metrics. This access is:

Read-only — Symptio never writes data to HealthKit
On-device only — HealthKit data is processed entirely on your device and is never transmitted anywhere
Never used for analytics — HealthKit data is never included in the anonymous usage statistics described below, and is never used for analytics or advertising of any kind
Optional — you can use Symptio without granting HealthKit access
Controlled by you — you choose exactly which health categories to share via iOS Health permissions

Specifically, Symptio may read: heart rate, sleep analysis, step count, and active energy burned.

For details on how Apple handles HealthKit data, see Apple's Health Privacy Overview.

iCloud Sync

If you enable iCloud sync, your symptom data is synced through Apple's iCloud (CloudKit). This means:

Data is stored in your personal iCloud account, protected by your Apple ID
Data is encrypted in transit and at rest by Apple
We (Smart Kiitös) have zero access to your iCloud data
If you stop using iCloud sync, your data remains on your device

For details on how Apple handles iCloud data, see Apple's iCloud Privacy Overview.

Anonymous Usage Statistics

To understand which features are actually used, so we can improve the app, Symptio counts a few in-app events on your device. After a day is over, it uploads one summary record for that day to Apple's iCloud (CloudKit) servers, into a public CloudKit database belonging to Smart Kiitös. This is completely separate from your health records, which stay in your own private iCloud database as described above. No third-party analytics service is involved, and we run no servers of our own.

What the record contains

Which app it comes from, and the date
The app version
Your device's region setting (the country chosen in system settings — not your location)
Whether you have Pro or not
A coarse “days since install” bucket: 0, 1–6, 7–29, 30+, or “existing user”
Counts of in-app events: which screens were opened, which features were used, which multi-step flows were started or completed, which errors were shown, when the paywall was shown or closed, and purchases

What it never contains

No health information of any kind: no symptom names, severities, notes or photos, no cycle, bathroom or weight data, and no family profile names
Nothing from Apple Health (HealthKit) — Apple prohibits this, and we don't do it
No name, email address, Apple ID, device identifier or advertising identifier

Apple's servers attach an opaque random identifier to each record. We do not read it, and we cannot link records to a person or across days.

These statistics are not linked to your identity, not used for tracking, not used for advertising, and never shared with or sold to anyone. In the App Store privacy label they are declared as Usage Data › Product Interaction, used for Analytics, not linked to you, and not used for tracking.

                You can turn this off in Symptio's Settings. It is on by default; turning it off stops uploads and deletes any counts not yet sent.
            

What We Don't Collect

                We never collect your health data or anything that identifies you. Apart from the optional, anonymous usage counts described above, Symptio sends us nothing, and we have no way to access your health data.
            

No email addresses or phone numbers
No account registration required
No location data
No browsing history, and no usage analytics linked to you — the anonymous daily counts above are the only usage information, and they cannot be tied to a person
No device identifiers or advertising identifiers
No third-party tracking SDKs
No health data is ever sent to our servers (we don't have servers)

PDF/CSV Export

Symptio allows you to export your symptom data as PDF or CSV reports. These reports are generated entirely on your device. The exported files are shared using the iOS share sheet — where you send them is your choice.

Notifications

Symptio uses local notifications (on your device) to remind you to log symptoms. These notifications are processed entirely on your device and are never sent to any server.

Subscriptions & Payments

Purchases are handled entirely by Apple through the App Store. We do not receive or store any payment information (credit card numbers, billing addresses, etc.). Apple processes all transactions according to their privacy policy.

Third-Party Services

                Symptio uses no third-party services. There are no third-party analytics, crash reporting, advertising, or social media SDKs in the app.
            

The only external services used are Apple's CloudKit (iCloud) for optional sync and for the anonymous usage counts, and Apple's HealthKit for optional health data correlation, both governed by Apple's privacy policy.

Data Retention & Deletion

All your data is stored on your device and/or your iCloud account
Deleting the app removes all local data
To remove iCloud data, you can delete it from your iCloud storage in iOS Settings
We have no servers and retain no copies of your health data
Anonymous usage counts are kept as aggregate statistics and cannot be tied to a person

Children's Privacy

Symptio does not knowingly collect information from children under 13. The app does not require any personal information to function. Family profiles are stored locally and are never transmitted to us.

Changes to This Policy

We may update this privacy policy from time to time. Changes will be posted on this page with an updated date. Continued use of the app after changes constitutes acceptance of the updated policy.
