Privacy Policy

Last updated: April 17, 2026 · Effective Date: April 17, 2026

SUMMARY

MedNav is designed to protect your health information. Your medications, supplements, and vitamins are stored only on your device. We do NOT collect your name, email, phone number, or any personal identifiers. When you scan a label or ask for information, we send the relevant data (the photo or text you provided) to our AI provider for processing and return the result to you. We never sell your data.

1. Who We Are

MedNav (the "App") is operated by MedNav ("we," "us," "our"). This Privacy Policy describes how we handle information in connection with the App. If you have questions, contact us at usemednav@gmail.com.

2. Information We Do NOT Collect

Your name, email, phone number, physical address, or date of birth
Device identifiers (IDFA, IDFV, advertising ID)
Your precise or approximate location
Your contacts, photos (other than those you voluntarily submit for scanning), calendar, or other device content
Account credentials (MedNav does not require an account)
Health data from Apple Health, Google Fit, or any third-party health platform

3. Information Stored On Your Device Only

The following is stored locally on your device using encrypted storage and is never transmitted to our servers:

Your list of medications, supplements, and vitamins ("your stack")
Dosages, frequencies, and personalized schedule
Theme preference (light or dark)
Notification preferences and timing overrides
Cached content (daily briefings, interaction reports)

Because this data lives only on your device, if you delete the App or clear its data, the information is permanently lost and cannot be recovered by us.

4. Information We Process Temporarily

To provide certain features, the App sends specific data to our backend, which relays it to our AI provider (OpenAI). The data sent:

Label Scanning

The photo you captured and the file type. No other device data is transmitted.

Item Identification

The name, dosage, and frequency you entered.

Daily Briefings & Interaction Checks

The names, dosages, and scheduling times of items in your stack.

Ask-MedNav Queries

The text of your question plus the names and dosages of items in your stack.

Schedule Edits

The natural-language command you entered plus your current schedule.

None of these requests are tied to your identity. We do not store them on our servers after returning a response. Our AI provider may retain data per their own policies (see OpenAI Enterprise Privacy), but it is not linked to any personal identifier of yours.

5. How We Use This Information

To identify medications and supplements you scan or type
To generate personalized briefings, schedules, and educational content
To check for potential interactions among items in your stack
To answer questions from the "Ask MedNav" feature
To improve App reliability (aggregate error logs, no personal data)

6. Third-Party Services

OpenAI

Powers identification, interaction analysis, briefings, and natural-language editing. Requests go through our backend with an app-level secret. Under OpenAI's API policies, API data is not used to train their models.

RevenueCat

Manages App Store subscriptions. Receives an anonymous user ID and subscription status. See revenuecat.com/privacy.

Apple App Store

Purchases are processed by Apple. We receive only subscription status, not payment details.

Vercel

Hosts our backend. May log request metadata (IP, timestamp) for operational purposes, not linked to you personally.

7. Permissions We Request

Camera: Only when you tap "Scan Label." Captures the image for identification; images are discarded after processing.
Photo Library: Only when you tap "Upload Photo." Reads the photo you select.
Notifications: Only if you enable them. Reminders are generated locally on your device.

You can revoke any permission at any time in your device Settings.

8. Children's Privacy

MedNav is intended for users aged 13 or older. We do not knowingly collect information from children under 13. If you believe a child has used the App, please contact us.

9. Data Retention

We do not store your personal information on our servers. Our backend retains transient operational data (timestamps, aggregate errors) for up to 30 days to diagnose technical issues, after which it is purged.

10. Your Rights

Depending on your jurisdiction (GDPR, UK GDPR, CCPA, LGPD, PIPEDA, Quebec Law 25, and others), you may have rights including access, correction, deletion, portability, and objection. Because the App does not store personal data on our servers, most of these rights are fulfilled automatically — your data is fully in your control on your device.

To exercise any right or ask a question, email usemednav@gmail.com. We respond within 30 days.

11. International Transfers

Our backend and AI providers may process requests in data centers outside your country, including the United States. By using the App, you acknowledge this. We rely on standard contractual clauses and provider-level safeguards for any such transfers.

12. Security

We use industry-standard security: encrypted storage on-device, HTTPS for all network requests, an app-level secret to authenticate API calls, and no long-term storage of personal data. No system is 100% secure; report suspected vulnerabilities to usemednav@gmail.com.

13. Changes to This Policy

We may update this Policy. Material changes will be announced in-app. Your continued use after a change constitutes acceptance.

15. Health and Safety Disclaimer

MedNav provides educational and organizational information only. It is not a medical device, does not diagnose or treat any condition, and is not a substitute for professional medical advice. Always consult a licensed healthcare professional before starting, stopping, or changing any medication, supplement, or vitamin. In case of medical emergency, contact your local emergency services immediately. Do not rely on the App for any decision that affects your health.
