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
- Your health logs stay on your device and, if you're signed into iCloud, in your own private iCloud account. We never receive your health content and cannot read it.
- There is no Symply login. Optional sync uses your Apple ID / private iCloud only.
- We do not collect usage analytics today. If we add any, it will be opt-in — off unless you turn on "Share usage data" — and limited to how the app is used and whether it crashes, never your symptom values, notes, medications, or Apple Health readings.
- No advertising networks and no selling of health data.
- You can delete your on-device / iCloud health data anytime 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 (health content)
Daily check-ins (symptom scales, flare flags, body areas, toggles, notes), your profile (optional name, conditions), medications, doses, and appointments. This stays on your device and optional private iCloud.
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, workouts, and menstruation dates. Menstruation is used only for cycle-aware insights and visit prep — Symply does not request fertility samples such as cervical mucus, ovulation tests, or sexual activity. Symply has read-only access and never writes to Apple Health. Activity and recovery readings may be copied onto your symptom logs when you save a check-in; menstruation dates are read on demand and are not entered as symptom logs. HealthKit readings are not sent to our analytics or crash tools.
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. Insight content is not uploaded to Cherrywig.
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. Health content is not sent to Cherrywig Studio for phrasing.
Product health metrics (opt-in)
Symply does not send us usage analytics today. Apple provides every developer with aggregate App Store reports (downloads, crash counts, and similar) that we cannot tie back to you.
If we add in-app usage measurement, it will be opt-in under You → Privacy → Share usage data and stays off until you turn it on. It would be limited to information such as:
- App opens, rough progress steps (onboarding finished, first check-in saved, insights unlocked), and which screens were opened
- Crash logs, hang/performance diagnostics, device model, and OS version
- App Store purchase and subscription status (once paid features ship)
These events are designed not to include symptom scale values, free-text notes, medication names, condition lists, body-map locations, HealthKit quantities, or insight copy. Any vendor we use for analytics or crash reporting would process this on our behalf under agreements limiting use to providing those services. We do not use this data for advertising or sell it.
Where your information is stored
- Health content: on your device first; in your own private iCloud if you're signed in. We cannot access your iCloud health data.
- Product health metrics: none held by us today. If you opt in later, they would sit with our analytics and crash-reporting providers (and Apple for App Store purchases) only as long as needed to operate, secure, and improve the app.
- A small summary on your device powers the home-screen widget (streak, today's status, and optionally a short insight snippet). That summary is not encrypted separately from your device.
What we do not do
- No advertising or marketing use of health data.
- No selling or sharing health data with data brokers.
- No ad networks or cross-app tracking for ads.
- No Cherrywig server that stores your symptom logs or HealthKit readings.
When information leaves the app
- iCloud sync (automatic, if enabled) — health content to your private Apple account.
- Exports you choose — visit-prep PDF or text via the iOS share sheet, only where you direct it.
- Product health metrics — only if you opt in; usage and crash events to our service providers as described above.
Notifications
Reminders may appear on your lock screen. Weekly insight notifications use a generic prompt to open Symply — pattern details stay in the app (and may appear on the home-screen widget). Daily check-in reminders may include a general medication prompt without 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.
- Product metrics: turning off "Share usage data" (or deleting the app) stops any collection. For access or deletion requests about analytics associated with your use of Symply, contact us at the email below.
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. Health content lives on your device and iCloud, so you can exercise those rights directly in the app. For product health metrics held by us or our processors, contact symply@cherrywigstudio.com.
Children's privacy
Symply is not directed at children under 13.
Security
Your health data is protected by your device security (such as your passcode, Face ID, or Touch ID) and Apple's iCloud security. You can also turn on App Lock under You → Security so Symply asks for Face ID, Touch ID, or your device passcode again after you leave — useful on a shared phone. Because we do not hold a central store of your health logs, that content is not exposed in a Cherrywig database. Any product metrics you opt into are protected with industry-standard controls at our providers. Keeping your device and Apple ID secure remains essential.
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.
