Anthos ("we," "our," or "the app") is committed to protecting your privacy. This Privacy Policy explains what information we collect, how we use it, and your rights regarding your data.
- Your symptom, medication, and threshold logs stay on your device — we never receive or store them.
- Apple Health is optional: data is read only if you connect it, used only to personalize your daily reading, and never used for advertising or to train AI.
- If you connect Apple Health, Anthos shares your Health-derived data with Anthropic (our AI provider) to generate your reading — only with your explicit consent, which you can withdraw at any time.
- We never sell your personal data or use it for advertising, and we do not track you across apps or websites.
- We use your location only to retrieve local pollen, air quality, and weather data.
1. Information We Collect
1.1 Information Stored on Your Device Only
The following data is stored on your iPhone using Apple's on-device database (SwiftData). We never receive or store it on our servers. It is used on-device to personalize your experience; where a premium feature sends a derived signal to a third party to generate your reading, that transmission is described in Sections 1.2 and 1.4:
- Allergen selections — the pollen types you've told Anthos to track (e.g., oak, ragweed, grass)
- Symptom logs — any symptoms you record through the daily check-in (sneezing, eye irritation, congestion, fatigue scores)
- Medication log entries — any medications you voluntarily log for personal tracking purposes
- Personal threshold data — sensitivity patterns Anthos learns from your symptom history over time
- App preferences — your notification settings, onboarding completion status, and display preferences
We cannot access, read, recover, or view this data. If you delete the app, this data is permanently deleted.
1.2 Information Transmitted to Third-Party Services
To provide you with accurate environmental data, Anthos sends limited information to the following services:
What is sent: Your approximate location (latitude and longitude coordinates)
Why: To retrieve pollen counts, air quality index, and weather conditions for your area
Retention: Google processes these requests according to their privacy policy. We do not store your location on any server.
What is sent: Environmental data for your area (pollen counts, AQI values, weather conditions), and — only if you connect Apple Health — signals derived from your Apple Health metrics (sleep, heart-rate variability, resting heart rate) and from your in-app check-ins, used to personalize your daily reading and "Decoder" insight. We do not send your name, exact location coordinates, account identifiers, or the raw logs stored on your device.
Who it goes to: Anthropic, PBC, which operates the Claude AI model that generates your reading. This is a third-party AI service.
Your consent: Environmental readings use the data above with no health information. Apple Health–derived data is sent only after you explicitly connect Apple Health and agree in the app, and only from that point forward. You can disconnect Apple Health at any time, which stops all further sharing.
Why: To generate a natural-language daily allergy reading personalized to your conditions and, for connected users, to your body's signals.
Use & protection: Anthropic processes these requests solely to generate your reading. Your data is not used for advertising or marketing, is not used to train AI models, and is not sold or shared further. Anthropic processes the request and does not retain it for these purposes.
1.3 Information We Do NOT Collect
We do not collect, store, or have access to:
- Your name, email address, or contact information
- Your Apple ID or any account credentials
- Your precise location history (coordinates are used transiently and not logged)
- Your browsing history, contacts, photos, or files
- Device identifiers, advertising IDs, or tracking tokens
- Usage analytics, crash reports, or behavioral data
- Financial information, payment details, or purchase history
1.4 Apple Health (HealthKit)
Apple Health is optional. Anthos works fully without it. If you choose to connect it, Anthos requests read-only access to exactly three data types, and only after showing you an in-app explanation of what is read, why, and where it is sent:
- Sleep analysis — to see how your rest compares to your own recent baseline
- Heart-rate variability (HRV) — a signal your body may be under strain
- Resting heart rate — read alongside the above for context
How this data is handled:
- Read-only and opt-in. Anthos never writes data back into Apple Health, and reads nothing unless you explicitly connect it.
- Sent to Anthropic only with your consent. When connected, signals derived from these three metrics are sent to Anthropic (our third-party AI provider) to personalize your daily reading, as described in Section 1.2. This happens only after you agree in the app, and only from that point forward.
- Used only for your reading. Your Apple Health data is never used for advertising or marketing, never used to train AI models, never sold or shared with data brokers, and never stored in iCloud by Anthos.
- Under your control. You can disconnect Apple Health at any time in the app or in iOS Settings > Privacy & Security > Health. Disconnecting stops all further reading and sharing immediately.
2. How We Use Information
- Environmental data requests are used solely to display current and forecasted pollen, air quality, and weather information within the app.
- AI-generated readings are created from your environmental data and, for users who connect Apple Health, signals derived from your Apple Health metrics and in-app check-ins. These signals are sent to Anthropic only to generate your reading, only with your consent, and are never used for advertising or to train AI models (see Sections 1.2 and 1.4).
- On-device data is used locally to personalize your experience, learn your sensitivity patterns, and display your history. Your raw logs are not uploaded; only the derived signals described in Sections 1.2 and 1.4 are shared, and only with your consent.
3. Data Sharing
We do not sell, rent, license, or trade your personal data, and we never share it for advertising, marketing, or use-based data mining.
The only parties we share data with are the service providers described in Section 1.2 — Google (for environmental data) and Anthropic (to generate your reading) — and only the limited data described there, solely to operate the features you use. For Apple Health–derived data, this sharing happens only after your explicit in-app consent (see Section 1.4). These providers are bound to process your data only to deliver the service and may not use it for advertising or to train AI models.
4. Data Retention
- On-device data: Retained on your device until you delete it within the app or uninstall the app. We have no ability to access or delete this data remotely.
- Apple Health data: Not stored on our servers or in iCloud. Health-derived signals are sent to Anthropic only to generate your reading and are not retained by Anthos.
- API requests: Processed in real-time by Google and Anthropic according to their respective data retention policies. We do not maintain logs of API requests.
5. Data Security
All data transmitted between Anthos and third-party APIs is encrypted using TLS 1.2 or higher. On-device data is protected by Apple's iOS security architecture, including device encryption and the iOS sandbox.
6. Children's Privacy
Anthos is not directed at children under the age of 13. We do not knowingly collect any information from children under 13. If you believe a child under 13 has used the app in a way that concerns you, please contact us.
7. Your Rights
For All Users
- You can delete all on-device data at any time by uninstalling the app
- You can modify your allergen selections and preferences at any time within the app
- You can revoke location permissions at any time through iOS Settings
- You can disconnect Apple Health at any time — in the app or in iOS Settings > Privacy & Security > Health — which immediately stops all health reading and sharing
For European Economic Area (EEA) Residents — GDPR
Under the General Data Protection Regulation, you have the right to access, rectify, erase, restrict processing, and port your personal data. Because Anthos stores data exclusively on your device and does not maintain user accounts or server-side databases, you exercise these rights directly through the app and your device settings. No request to us is necessary.
Our legal basis for processing location data is your explicit consent, which you grant through the iOS location permission dialog and can revoke at any time.
For California Residents — CCPA / CPRA
Under the California Consumer Privacy Act and California Privacy Rights Act, you have the right to know what personal information is collected, to delete it, and to opt out of its sale. Anthos does not sell personal information. We do not share personal information for cross-context behavioral advertising. All data is stored on your device and under your direct control.
8. Third-Party Links
Anthos does not contain links to third-party websites or services within the app experience, except for this Privacy Policy and our Terms of Service, which are hosted on our website.
9. Changes to This Policy
We may update this Privacy Policy from time to time. If we make material changes, we will notify you through the app or by updating the "Last Updated" date at the top of this page. Your continued use of the app after changes constitutes acceptance of the updated policy.
