Privacy Policy
Last updated: 6 July 2026
Seralog is private by design. Your health information — your labs, injections, check-ins and reminders — is stored on your iPhone. Seralog has no account, runs no servers of its own for your data, and its App Store privacy label is Data Not Collected.
1. Information Seralog collects
None that identifies you. Everything you enter — lab results, injections, symptom check-ins, reminders and settings — is saved locally in the app's on-device database. We do not have accounts, we do not ask for your name or email to use the app, and this information is never transmitted to us.
2. No analytics, ads, or tracking
Seralog contains no third-party analytics SDKs, no advertising, and no cross-app or cross-site tracking. We do not build a profile of you and we do not sell or share your data — because we never receive it.
3. Subscriptions (Seralog Plus)
If you purchase Seralog Plus, the transaction is handled by Apple through the App Store. We use RevenueCat to manage subscription entitlements (to know whether Plus is active). For this, Apple and RevenueCat process purchase and receipt information and an anonymous, app-generated identifier — never your health data. Their handling of that purchase data is governed by Apple's and RevenueCat's own privacy policies. Seralog itself does not receive any personal or health data in this process.
4. Where your data lives & backups
Your data lives on your device. Seralog offers an optional backup feature that creates a plain JSON file which you choose to export and store wherever you like (for example, Files or your own cloud). That file is under your control; we never see it.
5. Notifications
Reminders are delivered as local notifications scheduled on your device. They are not sent through any external push server.
6. Children
Seralog is intended for adults managing their own therapy and is rated 17+. It is not directed to children, and we do not knowingly collect information from anyone.
7. Your control
- Deleting the app removes its on-device data from your iPhone.
- You can export a backup at any time, and import it on a new device.
- You can manage or cancel a Seralog Plus subscription in your Apple ID settings.
8. Changes to this policy
If this policy changes, we will update the date above and post the revised version here.
