Effective 5 September 2026
Short version: Baseline does not collect your data. Your blood-sugar readings live on your device and in your own private iCloud — we never see them, and there are no ads, no analytics, and no third-party trackers.
Baseline (“the app”, “we”, “us”) is a simple, private blood-sugar log published by Erised Development Ltd. This policy explains what the app does with your information.
Nothing. We do not collect, transmit, sell, or have access to your readings or any personal information. Baseline has no analytics SDKs, no advertising, and no third-party trackers.
With your explicit permission, Baseline can read blood-glucose values from, and write the readings you log to, Apple Health. This data stays on your device and in your Apple account. You can turn this off at any time in the app or in the Health app, and revoke access in Settings → Privacy & Security → Health.
Baseline Plus subscriptions and the Lifetime purchase are handled entirely by Apple through the App Store. We never receive your name, card, or payment details — only anonymous, aggregate sales information Apple provides to all developers.
Baseline is not directed at children and does not knowingly collect information from anyone. Because we collect no data at all, none is collected from children either.
If this policy changes, we’ll update this page and revise the effective date above.
