Symply Privacy Policy
Symply is made by Cherrywig Studio LLC ("we," "us," or "our"). This policy explains what happens to your information when you use the Symply app. We've written it in plain language on purpose — you shouldn't need a law degree to understand what an app does with your health data.
The short version
- Everything you log stays on your device and, if you're signed into iCloud, in your own private iCloud account.
- We have no servers. We never receive your health data and cannot read it.
- We don't use analytics, advertising, or tracking.
- We never sell or share your health data with anyone.
- You can delete everything at any time from inside the app.
Who is responsible for your data
Cherrywig Studio LLC is the data controller for privacy law purposes (including the GDPR).
What information Symply handles
Information you enter yourself
Daily check-ins (symptom scales, flare flags, body areas, toggles, notes), your profile (optional name, conditions), medications, doses, and appointments.
Information from Apple Health (only if you allow it)
If you grant permission, Symply reads: step count, exercise minutes, sleep analysis, heart-rate variability, resting heart rate, and workouts. Symply has read-only access and never writes to Apple Health. Relevant readings may be copied onto your symptom logs when you save a check-in.
Information Symply creates on your device
Symply produces insights, correlations, and summaries about your patterns. Pattern detection is always calculated on your phone from your logs using deterministic rules — it does not depend on Apple Intelligence and is never sent anywhere.
Apple Intelligence (optional)
On iPhones that support Apple Intelligence, Symply may optionally use on-device Apple Intelligence to phrase insight headlines, weekly summaries, visit-prep text, and similar wording. This is cosmetic only: the underlying patterns come from your logs, not from the model inventing new facts.
You can turn phrasing on or off anytime under You → Apple Intelligence. When it is off, or on a device that does not support it, Symply uses template wording instead. Nothing is sent to Cherrywig Studio or any server we operate.
Where your information is stored
- On your device first.
- In your own private iCloud, if you're signed in — so data can return after reinstall or on a new device.
- We cannot access your iCloud data.
- A small summary on your device powers the home-screen widget (streak and today's status).
What we do not do
- No advertising or marketing use of health data.
- No selling or sharing with data brokers.
- No third-party analytics or tracking SDKs.
- No server that receives or stores your data.
When information leaves the app
- iCloud sync (automatic, if enabled) — to your private Apple account.
- Exports you choose — visit-prep PDF or text via the iOS share sheet, only where you direct it.
Notifications
Reminders may appear on your lock screen. Weekly insight notifications may describe patterns in words (numbers are stripped). Medication reminders do not show medication names. You can turn notifications off in iOS Settings or in Symply.
How to delete your information
- Delete All My Data in the You tab — erases logs, medications, profile, appointments, preferences, widget state, and cancels notifications. Deletions propagate to iCloud.
- Delete the app — removes on-device data. Use Delete All My Data first if you want the iCloud copy removed too.
Symply cannot delete data stored in the Apple Health app — that belongs to Apple Health.
Your privacy rights
Depending on where you live (GDPR, CCPA/CPRA, Washington MHMDA, etc.), you have rights to access, correct, delete, and export your data. Because your data lives on your device and iCloud, you can exercise these directly in the app.
Children's privacy
Symply is not directed at children under 13.
Security
Your data is protected by your device security and Apple's iCloud security. We never receive your data, so there is no central store for an attacker to target.
Medical advice
Symply is a personal tracking tool, not a medical device. It does not provide medical advice or diagnosis.
Changes to this policy
We will update the "Last updated" date and, for significant changes, provide notice in the app.
