Privacy Policy

Last updated: 2026-09-21

1. What stays on your device

Everything you record — blood pressure, pulse, notes, tags, names you choose to type, weight and other optional records, reminders and settings — is stored on your device by the App. It is not transmitted to us and we cannot read it.

2. Camera

The App asks for camera access only so it can read the numbers shown on the display of your blood pressure monitor. The image is processed on your device using the operating system's built-in text recognition. Photographs are not saved by the App and never leave your device. If you prefer, you can type every reading by hand and never grant camera access.

Bluetooth (Japan only). In the Japanese App Store, Premium can receive readings from a Bluetooth blood pressure monitor. Bluetooth is used only to talk to the monitor you register; the readings are shown to you first and are saved on your device only when you choose to save them. Nothing is sent to us or to any other server.

3. Microphone

The App does not use the microphone and does not ask for microphone access. If you dictate a note, that is your keyboard's dictation feature, handled by the operating system.

4. Health app

If you turn it on, the App can write the readings you enter to Apple Health, and read blood pressure and related data from Apple Health, so that your records are in one place. This exchange happens on your device between the two apps. We never receive Health data, and Health data is never used for advertising or shared with third parties. You can withdraw this permission at any time in the Health app.

5. iCloud sync (optional, Premium)

If you turn on iCloud sync, your records are stored in the private database of your own iCloud account, so they can appear on your other devices. That storage belongs to you and is governed by Apple's privacy policy. We have no access to it and operate no server of our own. Turning sync off keeps the records on the device.

6. Backups you make

When you save a backup file or export a CSV or PDF, the file goes where you choose to put it — the Files app, iCloud Drive, AirDrop, a message, a printer. The App does not upload it anywhere.

7. Purchases

Subscriptions are processed by Apple. We receive no card number, no billing address and no name — only the anonymous confirmation from the App Store that a subscription is active, which is checked on your device.

8. If you write to us

The support form on this site sends your message, and the email address you choose to provide, to our support mailbox so that we can reply. We use it only to answer you, we do not add it to any mailing list, and we delete correspondence once it is no longer needed. Leaving the email field blank is fine if you do not need a reply. The form also records the time, your browser's user-agent string and, for a short period, a hashed form of your IP address, solely to stop automated spam.

9. No third-party tracking

The App contains no advertising SDK, no analytics SDK, no crash-reporting service that identifies you, no social login and no tracking identifiers. We do not collect an advertising identifier and we do not track you across apps or websites. This website sets no cookies.

10. Children

The App is not directed at children and we do not knowingly collect information from anyone. As nothing is collected, nothing about a child is held by us.

11. Your rights

Data protection law gives you rights to access, correct, export and delete personal data held about you. We hold none, so there is nothing for us to return or erase. The data in the App is under your direct control: you can read, edit, export and delete it in the App at any time, and deleting the App removes it from the device. If you have written to us, you may ask us to delete that correspondence through the support form.

12. Changes

If this policy changes, the new version will appear on this page with a new date above.

13. Contact

Privacy questions can be sent through the support form. The data controller is Ask White, Japan.
