Privacy policy: Plainweeks (working name): Pregnancy Weeks

Status: this app is in development and has not been released yet. This policy describes what the app is designed to do, as written in its specification; it will be reviewed again before release.

In short

The app shows the week of your pregnancy and keeps what a midwife visit needs. Everything stays on this phone. It has no account, no advertising, no analytics and no tracking, and it contains no network code. The app records and calculates from what you enter; it is not a medical device and does not diagnose, treat, cure or prevent any medical condition.

What is stored on your phone

In a local database inside the app, encrypted on the phone and kept out of the operating system's backups. It is all entered by you:

• Your due date and how it was worked out, scan dates, and appointments with your questions.
• Movement and contraction sessions, weight and blood pressure numbers, symptoms and journal entries, checklists, and, if you add them, bump photos. Photos are re-saved without photo metadata such as location and are kept inside the encrypted database.
• Your settings, such as lock options, reminders, language and theme.
• The database key and a hash of your PIN are kept in the phone's secure storage, not in the database.
• Notifications are neutral in wording and never contain measurements.

Permissions

• Notifications: asked only when you switch on your first reminder.
• Face ID or fingerprint: used if you turn on the optional app lock.
• Photos are chosen through the system picker and need no permission. The app blocks camera, microphone, location, Bluetooth, contacts and Health Connect access, and has no internet permission in Android release builds. There is no HealthKit use.
• Android also uses boot-completed so reminders return after a restart, vibrate, and keep-awake on the timer screens.

Backup and export

Backups are always encrypted with your password and go only where you put them, as a file you share or a folder you choose for automatic backup. You can export a PDF summary for your midwife, CSV files and a calendar (ICS) file of your appointments. The only ways data leaves the phone are a file you share, a backup you put somewhere, and a link you tap.

What the app does not do

No advertising, no analytics, no accounts, no cloud, no network use, no rating prompt. A pregnancy that has ended can be archived without comment, with no countdown and no notifications.
