Privacy Policy

Effective date: June 17, 2026 · Last updated: June 17, 2026

Privacy-first by design. All your entries — including photos — stay on your device. We do not collect, transmit, store on our servers, sync, share, or sell your information. There is no analytics, no advertising, and no third-party tracking.

Who we are

Fibrolog (“the app”, “we”) is provided by Softgrove, an independent developer based in Japan. Contact: softgrove@duck.com.

What data the app handles

You may record flares (pain severity, fatigue, brain fog, sleep quality, affected body areas), suspected triggers (overexertion, poor sleep, weather, stress, food), daily factors, free-text notes, and optional photos you choose to attach to a flare entry as a personal visual reference (“your entries”). Your entries and photos are stored only locally on your device using Apple’s on-device database and the app’s protected file container. We never receive this data.

We do not collect: name, email, account credentials (the app has no account), location, contacts, advertising identifiers, or usage analytics.

Photos

Photo attachment is optional and used only as a personal visual reference alongside your written flare entry. Any photos you attach are saved only in the app’s on-device container with file protection. They are never uploaded, synced, shared, or analyzed by us, and the app performs no automated diagnosis on them. You can delete any photo or all data at any time from Settings.

Health information

Your entries may relate to your health. Because this information never leaves your device through us, we are not in a position to use it for any purpose. For Washington State residents (My Health My Data Act): we do not collect, process, share, or sell “consumer health data.” Your entries are stored solely on your device.

Export, import, and deletion

Subscriptions and payments

Premium subscriptions are sold and processed by Apple through the App Store. We do not receive or store your payment information.

Notifications

If you enable reminders, the app schedules local notifications on your device. No notification data is sent to us or any third party.

Children

Fibrolog is not directed to children under 13 (or the minimum age in your region) and collects no information from anyone.

Third parties

The app uses only Apple system frameworks. There are no third-party SDKs, analytics, advertising networks, or external servers.

Changes

We may update this policy. Material changes will be reflected here with a new “Last updated” date.
