This Privacy Policy applies to the Lumen iOS application and the support or policy pages that link to it. "Lumen," "we," and "us" refer to the developer of Lumen. By using Lumen, you acknowledge the practices described below.
Lumen does not operate an account system or a cloud database for your journal. Your entries are stored locally on your iPhone. We do not sell health information, use advertising SDKs, or use cross-app tracking.
1. Scope and responsibility
Lumen is a self-tracking and information-organizing tool for adults. It is not a medical device, does not diagnose conditions, does not recommend medication or dosage, and does not provide emergency medical services.
The developer listed on the Lumen App Store page is responsible for this app. For privacy questions, contact newlifebirdstudio@gmail.com.
2. Information in Lumen
Lumen lets you choose to record information such as:
- headache, symptom, medication, and treatment entries;
- severity, duration, location, symptoms, notes, and perceived relief;
- daily context such as sleep, weather-related factors, cycle-related context, and activity impact; and
- medication plans, reminder preferences, appearance settings, and other app preferences.
This information can be sensitive health information. The current version stores it in Lumen's local on-device data store protected by iOS. Lumen does not automatically send journal entries, medication information, notes, location, HealthKit values, or report content to us.
Information we do not request
Lumen does not require an account, name, phone number, address, or contact list. The app does not access HealthKit or precise location in the current version.
Information we receive when you contact us
If you email support, we receive the information you choose to include, such as your email address, app version, device information, and a description of the issue. We use it only to respond to your request and improve support.
3. Apple services and sharing
In-app purchases
Lumen Plus purchases are processed by Apple through the App Store and StoreKit. We do not receive your payment card details or Apple Account password. Apple may provide purchase and entitlement information needed to confirm access to the features you bought. Apple's handling of that information is governed by Apple's own privacy policy.
Local notifications
If you enable reminders, Lumen schedules notifications on your device using Apple's local notification framework. The app does not send notification content to a Lumen server.
Exports and sharing
When you request a PDF report, JSON backup, or CSV export, Lumen creates the file on your device and presents Apple's share sheet or file picker. The destination you select, such as Files, Mail, or another app, receives the file. That destination's privacy policy then applies. Lumen does not automatically upload exported files.
Backups and device services
Lumen does not operate its own cloud sync service. If you include the app in an iOS device backup, Apple may process that backup under Apple's terms and privacy policy. Removing a file from Lumen does not remove copies you previously exported or included in a device backup.
Advertising and tracking
The current version does not include advertising SDKs, cross-app tracking, or a third-party analytics SDK. Lumen does not sell or share your health information for advertising.
4. Your choices and data controls
- Review and edit: You can view, update, or delete entries in the app.
- Delete local data: Settings includes a "Delete all data" action for records, daily context, and medication plans. Deletion removes the data from Lumen's local store on that device.
- Export a copy: You can create a Lumen backup or CSV export from Settings. You are responsible for protecting copies stored outside the app.
- Notifications: You can turn reminders off in Lumen or in iOS Settings.
- Purchases: You can restore a purchase in Lumen. Subscriptions are managed or cancelled in your Apple Account subscription settings. A lifetime purchase does not expire or renew.
Because Lumen does not maintain a remote account or cloud database of your journal, there is generally no server-held journal profile for us to retrieve or erase. If you have a privacy request or believe we have received personal information through support, email us and we will respond to the extent required by applicable law.
5. Retention and security
Your local entries remain on the device until you edit or delete them, delete all data in Lumen, or remove the app. Lumen relies on iOS security features, including app sandboxing and Data Protection. No method of storage or transmission is completely secure, so keep your device passcode private and treat exported files as sensitive.
Support emails are retained only as long as reasonably needed to answer the request, maintain support records, resolve disputes, or meet legal obligations.
6. Children's privacy
Lumen is intended for adults and is not directed to children. We do not knowingly collect personal information from children. If you believe a child has provided personal information to us through support, contact us so we can review and delete it where appropriate.
7. Changes to this policy
We may update this policy when Lumen's features, services, or legal requirements change. The "Last updated" date at the top of this page shows when the current version took effect. If a change is material, we will provide notice in the app or on this page when appropriate.
