Reefline Log

Privacy Policy

Last updated: 6 September 2026

Overview

Reefline Log is a one-time paid iPhone app for logging reef-tank water tests. We do not run ads, analytics, accounts, or tracking. We do not sell data. There is no Reefline server.

What we collect

We do not collect personal data. Test readings, tank names, custom metric definitions and readings, notes, target bands, reminders, and settings are stored on your iPhone in the app’s local database. Each reading and custom metric belongs to the tank you selected. We cannot see them.

iCloud (optional)

If you turn iCloud sync on, Apple stores that same private database in your iCloud account using CloudKit’s private database. That sync is between your devices and Apple, not us. You can turn it off in Data & About. We do not operate a backend and we cannot read your CloudKit data.

Export

CSV export is something you start. The file is written to a share sheet you control. We do not upload it.

Third parties

Reefline Log does not include advertising SDKs, analytics SDKs, crash reporters, or social logins. Optional iCloud uses Apple’s services under Apple’s privacy policy.

Notifications

Reminders are local notifications on your device. They are not push messages from a server. Titles are the ones you typed.

No account

The app does not require an account or an email address to function. If you email support, we see whatever you send in that email.

Children

The app does not collect personal information from anyone, including children under 13.

Changes

If this policy changes, we will post the update on this page with a new date.
