This Privacy Policy explains how LUMEN ("LUMEN", "we", "us") handles information when you use the LUMEN mobile application (the "App"). We've written it to be readable, not just legally complete. By using the App, you agree to the practices described here.
1. Information We Collect
a. Information stored on your device
By default, the content you create in LUMEN is stored locally on your device, including: your ritual steps and schedules; your product "shelf" (names, brands, costs, opened dates, notes); daily logs, streaks and XP; and any progress photos you capture. This information is not transmitted to us unless a feature you use requires it (see below).
b. Account information (optional)
You can use LUMEN without an account. If you choose to create one using Sign in with Apple or Google, we receive and store the account identifier, and the email address, name and profile picture you authorize the provider to share. Authentication tokens are stored securely in the device Keychain. An account lets us back up and sync your data across your devices.
c. Product scanning & AI features
When you scan a product by photo or use the AI Advisor, the relevant content — such as the product image or barcode and your question, along with relevant shelf context — is sent to our AI processing provider to generate a response (for example, to identify a product, its brand and typical shelf life, or to answer a self-care question). When you scan a barcode, the barcode number may also be sent to third-party product databases (such as Open Beauty Facts and Open Food Facts) to look up product details.
d. Camera & photo library
With your permission, LUMEN accesses your camera (as a live mirror during rituals and to scan or photograph products) and your photo library (to add product or progress photos). Photos are used only for the features you invoke and are stored on your device unless you use an AI scanning feature, which transmits the image for identification as described above.
e. Notifications
If you enable reminders, we schedule local notifications on your device at the times you choose. No notification content is sent to our servers.
f. Purchases
LUMEN Gold subscriptions are processed by Apple through the App Store. We do not receive or store your payment card details. We may receive a non-identifying signal that confirms whether you hold an active subscription.
g. Diagnostic information
We may collect limited, aggregated technical information (such as crash logs and basic usage events) to keep the App stable and improve it. This data is not used to identify you personally.
2. How We Use Information
- To provide the App's core features — your rituals, shelf, progress and reminders.
- To enable optional account backup and cross-device sync.
- To power AI product identification and the AI Advisor.
- To process and validate subscriptions.
- To diagnose problems, prevent abuse, and improve the App.
3. Data Sharing
We do not sell your personal information. We share data only with service providers who help us operate the App, and only as needed:
| Provider | Purpose | Data involved |
|---|---|---|
| AI processing provider | Product identification & AI Advisor responses | Product images/barcodes, questions, relevant shelf context |
| Open product databases (e.g. Open Beauty Facts) | Barcode product lookup | Barcode number |
| Authentication provider | Apple/Google sign-in | Account identifier, email, name |
| Apple | Subscriptions & payments | Handled entirely by Apple |
We may also disclose information if required by law or to protect the rights, safety and security of our users and the App.
4. Data Retention & Deletion
On-device data persists until you delete it or remove the App. If you created an account, you can delete your account and all associated server-side data directly within the App (Profile → Account → Delete Account), or by emailing us at the address below. Deletion is permanent.
5. Security
We use reasonable technical and organizational measures to protect your information, including secure transmission (HTTPS) and Keychain storage for credentials. No method of transmission or storage is 100% secure, but we work to protect your data.
6. Children's Privacy
LUMEN is not directed to children under 13 (or the minimum age of digital consent in your region), and we do not knowingly collect personal information from them. If you believe a child has provided us information, contact us and we will delete it.
7. Your Rights
Depending on where you live (for example, under GDPR or the CCPA), you may have the right to access, correct, export or delete your personal information, and to object to or restrict certain processing. To exercise these rights, use the in-app controls or contact us. We will not discriminate against you for exercising your rights.
8. International Users
Your information may be processed in countries other than your own, including the United States, where data-protection laws may differ. Where required, we put appropriate safeguards in place.
9. Changes to This Policy
We may update this Policy from time to time. We'll revise the "Last updated" date above and, for material changes, provide a more prominent notice in the App.
