Privacy Policy

Evenstone is a private, on-device logbook for carbohydrates, medications, health readings and mood.

Evenstone does not collect your data. There is no account, no sign-in, and no cloud service. The app makes no network connections of any kind. It behaves identically in aeroplane mode, because there is nothing for it to connect to. No information about you or your use of the app is ever transmitted to the developer or to anyone else.

This policy explains what that means in practice.

What Evenstone stores, and where

On your iPhone, in the app's own storage: your food log, the foods you create, your Quick-pick tiles and saved meals, your medications and their schedules, your record of doses taken, skipped or missed, a note of when you started or stopped a medication or changed your carb ceiling, any daily reflections you write, your mood entries if you turn mood tracking on, and your settings.

In Apple Health: your clinical readings: blood glucose, blood pressure, weight, waist measurement and insulin. Evenstone writes these to Apple Health and reads them back to show you your own trends. It does not keep a separate copy of them. Apple Health is part of iOS and is governed by Apple's privacy policy, not this one.

Evenstone also reads your step count from Apple Health, to show it on the Today screen. It never writes step data. Your mood entries are never written to Apple Health.

Nothing is stored anywhere else. There is no server.

Health data (HealthKit)

Evenstone asks for permission to read and write a specific, limited set of health data. You can grant or refuse any part of it, and change your mind at any time in Settings → Health → Data Access & Devices → Evenstone.

• Health data is used only to show your own information back to you.
• It is never used for advertising or marketing.
• It is never sold, shared with third parties, or used for data mining.
• It is never transmitted off your device by Evenstone.
• It is not used to make any diagnosis, recommendation, or dosing decision.

If you refuse Health access, Evenstone still works. Your food and medication log is kept in the app either way, and any reading that cannot be saved to Apple Health is held safely on your device and saved the next time access is available.

The only two things that can leave your device

Both require you to tap something. Neither happens automatically, and neither goes to the developer.

1. A backup file you export. In Settings, "Export my data" gathers your food log, custom foods, Quick-pick tiles, saved meals, medications, dose history, reflections, mood entries, medication and ceiling change notes, and settings into a single file, and hands it to iOS's standard share sheet. Where it goes is your choice: Files, AirDrop or email.

Two things to know about that file:

• It is not encrypted or password-protected. Anyone who can open it can read it. Keep it somewhere you trust.
• Your Apple Health readings are not in it. They stay in Apple Health, which has its own backup.

2. A summary page you share. The Trends screen can produce a one-page PDF of your last 90 days to give to a clinician. It is created on your device and handed to the share sheet, and Evenstone deletes its own copy as soon as the share finishes. Where it goes next is your choice. The summary does not include your mood entries or reflections.

Once you have sent either of these, what happens to it is outside Evenstone's control, the same as any other file you send from your phone.

What Evenstone never does

• No account, no sign-in, no profile
• No analytics, telemetry, crash reporting or usage tracking
• No advertising, and no advertising identifier (IDFA). Evenstone does not ask for App Tracking Transparency permission because it does not track you
• No third-party SDKs of any kind
• No access to your microphone, camera, photos, location, contacts, calendar or Bluetooth
• No selling or sharing of any information, because none is collected

Notifications

Medication reminders and optional nudges are scheduled locally on your device. There is no push server. A medication reminder never shows the medicine's name, on the Lock Screen or in the notification list, so a glance at your phone reveals only that you have a routine.

Deleting your data

Deleting the Evenstone app removes everything it stores on your device.

Your Apple Health readings are not removed, because they belong to Apple Health rather than to Evenstone. To remove those, use the Health app.

If you have exported a backup file or shared a summary PDF, those copies are wherever you sent them, and only you can delete them.

Children

Evenstone is not directed at children and does not knowingly collect information from anyone. It collects no information from any user of any age.

Food data

Nutrient information in Evenstone comes from AUSNUT 2023, © Food Standards Australia New Zealand, licensed under CC BY-SA 3.0 AU. It is bundled with the app and read from your device; no lookup is sent anywhere.

Changes to this policy

If this policy changes, the "last updated" date above will change with it. Because Evenstone collects nothing, any change is likely to be a clarification rather than a change to what happens to your data.
