Privacy Policy

Bumpline · Last updated 11 September 2026

Bumpline is a pregnancy diary. This policy explains what the app does with your information — which is, almost entirely, nothing. It is written to be read, not skimmed past; the whole of it fits on one screen because there is little to say.

The short version

• Bumpline has no account and no server of its own. There is nothing to sign up for.

• Everything you enter — dates, photos, notes, every record — stays on your iPhone, and, if you have iCloud turned on, in your own private iCloud storage, which we cannot read. None of it is ever sent to us.

• The app sends anonymous usage events to an analytics service (Amplitude): which screens and buttons are used, and whether a subscription was started, restored or cancelled. These are never linked to your name, your Apple ID or your diary, and they contain none of its contents. See "Usage analytics".

• The app makes one other network request, for a static list of baby names. It carries nothing about you.

• Payments are handled by Apple. We never see your card, your name or your address.

• Our App Store privacy label reads "Product Interaction — not linked to you", and this document is the longer form of that line.

Who we are

Bumpline is the operator of the app "Bumpline". If you have questions about this Privacy Policy, contact us at bumpline.support@gmail.com. We are the "data controller" for the purposes of data-protection law, although as you will see, there is very little data under our control.

What the app stores, and where

Bumpline keeps the following on your device:

• Your dating — the method you chose (last period or ultrasound) and the dates behind it. Everything else about your term is calculated from this each time, and never stored.

• Your photos — a reference to each weekly photo in your Photos library, a small thumbnail of it, the date it was taken and any note you wrote.

• Your tools — anything you enter into the checklists, appointments, weight log, name list, movement counter and contraction timer.

• Your settings — units, reminder day and time, and similar preferences.

None of this is sent to us. We have no way of seeing it.

iCloud

If iCloud is turned on for Bumpline in your iPhone's settings, the same information is stored in your private iCloud database, so it follows you to a new phone. This is Apple's CloudKit service, using your Apple Account. The data lives in a part of iCloud that only your devices can open; we have no access to it, and Apple handles it under its own privacy policy.

To keep sync working, Apple may send the app silent, invisible notifications when something changes on another of your devices. These are not messages to you and carry no content.

You can turn iCloud off for Bumpline at any time in Settings › [your name] › iCloud › Apps Using iCloud. The app then keeps working with the copy on the device alone.

Permissions the app asks for

Each is optional, asked for at the moment it is needed, and explained on screen at that moment.

• Camera — to take your weekly photo, with last week's shot showing through so you can line it up. Photos you take are saved into an album called Bumpline in your own Photos library.

• Photos — to let you pick existing photos for a week, and to save new ones. The app reads only the photos you select. It never deletes anything from your library: removing a photo in Bumpline removes it from the diary only.

• Calendar (write only) — to add an appointment to your calendar when you ask. The app can add events; it cannot read what else is in your calendar.

• Notifications — for one weekly reminder to take your photo, on the day and at the time you chose. There are no other notifications: nothing daily, nothing about your due date, nothing to bring you back.

The one network request

The name browser ships with a list of names inside the app. Once a week, when you open it, the app checks a content delivery network for a newer copy of that same list. This is a plain request for a static file: it carries no account, no identifier and nothing about you. Like any web request, it exposes your device's IP address to the network provider for the duration of the request; we do not receive or store it. If the request fails, or you are offline, the app quietly keeps the list it has.

Usage analytics

To see which parts of the app are used and which are not, Bumpline sends anonymous usage events to Amplitude, Inc. (United States). An event is the name of an action — "photo kept", "weighing added", "paywall shown", "subscription cancelled" — together with neutral details such as which tool, which plan, or a coarse count bucket, plus the app version, the device model and iOS version, and a random identifier that Amplitude assigns to the installation.

What is never sent: your name, e-mail or Apple ID; the advertising identifier (the app never asks for tracking permission); any date, weight, count, name, note or photograph you have written down; screen recordings or screen contents. The events cannot be used to identify you and are not shared with anyone else or used for advertising. Amplitude processes them on our behalf under its own privacy terms; they are kept for the period Amplitude retains analytics data and can be deleted on request to us.

Beyond this and the name list, Bumpline makes no other connection. There is no crash reporter and no advertising SDK in the app.

Purchases

Bumpline Full is a subscription sold through the App Store. Apple processes the payment and holds your payment details; we receive none of them. The app only asks Apple whether the subscription is active. Refunds and cancellation are handled by Apple — see Terms of Use for how.

Sharing

We do not share, sell or transfer your information to anyone, because we do not have it. The export feature exists so that you can hand your diary to whoever you choose — a PDF and your full-size photos, readable without Bumpline — and it works whether or not you subscribe.

Your rights

Under data-protection laws such as the GDPR you have the right to access, correct, export and delete your personal data. Because it is all on your device:

• Access and correction — open the app.

• Export — Settings › Export everything.

• Deletion — delete the app, which removes everything stored on the device. To remove the iCloud copy as well, delete Bumpline's data in Settings › [your name] › iCloud › Manage Storage.

There is nothing we would need to do on our side, and nothing we could do, since we hold no copy.

Children

Bumpline is intended for adults. We do not knowingly collect information from anyone under 16 — or, in practice, from anyone at all.

Medical information

Bumpline is not a medical device and does not give medical advice. The figures you enter — weight, movements, contractions — are shown back to you exactly as you entered them and are never interpreted. What they mean is for your midwife or doctor to say.

Changes to this policy

If the app ever starts doing something new with your data, this document will change first and the app will tell you inside itself. The date at the top is the date of the latest revision.
