A Truly Private Symptom Tracker: No Account or Health-Data Servers
No account. Private. No personal information is ever requested. Your health data stays on your iPhone by default. A backup option to your private iCloud is available. Trace Health never collects or sells your health data.
What “private” means in Trace Health, concretely
- No account required. Open the app and start logging. No email, no phone number, no sign-in. Ever.
- Local-only storage. Your symptom and lifestyle logs live in your iPhone's storage, protected by your device passcode or Face ID and iOS encryption.
- No servers. Trace Health has no backend that stores health data. There is nothing to hack, subpoena or sell.
- No health-data analytics. We never see what you log. Your symptoms are yours alone.
- Your export, your choice. PDF doctor reports and Apple Health sync happen only when you explicitly tap them.
- You control backup. The only optional backup is to your own personal Apple iCloud account, off by default, controlled by you, and never visible to us.
Why privacy matters for symptom data
A symptom diary is among the most sensitive data you can create. It can reveal a chronic illness, a mental-health condition, a reproductive-health situation or a disability, things you may not have shared with your employer, your insurer or even your family.
Most health apps upload this data to company-controlled servers. Even with good intentions, server-side health data can be breached, acquired in a company sale, requested by third parties, or used for analytics. Trace Health keeps health data on your iPhone by default, with optional private iCloud sync.
Private doesn't mean limited
Trace Health processes health data on-device and still does the full job of a modern symptom tracker:
- Log any of 60+ symptoms in one tap, with severity levels (mild, moderate, severe).
- See how each symptom evolves over days, weeks, months and the last year with interactive charts.
- Track daily lifestyle factors, food, sleep, stress, exercise, medications, and discover what triggers or relieves your symptoms.
- Generate doctor-ready PDF reports for appointments.
- Write symptoms into Apple Health as real Health entries (opt-in).
- Track a family member with multiple profiles.
- Use it in 9 languages.

| Apple Health integration | Writes symptoms into Health as real entries, alongside sleep and cycle | Varies; commonly read-only, or unavailable |
| Ads and health-data selling | No ads; Trace Health never sells health data | Varies by app; check its privacy policy and App Store privacy label |

Frequently asked questions
Is Trace Health really anonymous?
Yes, by architecture. Trace Health never asks who you are: no account, no email, no sign-in. Health entries stay on your device by default, with optional private iCloud sync. There is no Trace Health server-side record of you or your symptoms.
Does Trace Health require an account or email to use?
No. You download it, open it, and start logging. There is no sign-up screen anywhere in the app.
Can I use Trace Health completely offline?
Yes. Because all data is stored locally, every feature, logging, charts, insights, PDF reports, works without an internet connection.
What happens to my data if I delete the app?
It is deleted with the app. There is no copy on any server. If you enabled the optional backup to your own Apple iCloud account, that copy remains under your control in iCloud until you remove it.
If nothing is uploaded, how do I share my history with my doctor?
You generate a PDF report inside the app, a clear summary of frequency, severity and patterns, and hand it over or send it yourself. Sharing is always an explicit action you take, never something that happens in the background.
Track your symptoms privately. Download Trace Health and start logging in one tap: no account, no health-data servers, no compromise.
