Privacy Policy

Your data stays
on your iPhone.

The short version

Who we are

Abonné is an iPhone app for keeping track of your subscriptions, published by Fiston Niyonkuru. In this policy, "Abonné", "we" and "us" mean the app and its publisher. For questions, contact fiston.n@proton.me.

Your subscription information

Abonné stores the subscriptions you enter on your device. This includes service names, prices, currencies, billing dates and cycles, categories, notes, links, icons, and whether a subscription is paused or in a free trial. It also saves your preferences, such as your main currency and reminder time.

Accounts, advertising and tracking

Abonné doesn't require an account or a bank connection. It contains no advertising, analytics or third-party tracking SDKs, and it doesn't ask for access to your contacts, photos, location, microphone or advertising identifier. We don't sell, rent or share personal information, and we don't track you across other apps or websites.

Currency conversion

To convert prices into your main currency, Abonné downloads a general table of exchange rates against the US dollar from ExchangeRate-API (open.er-api.com). ExchangeRate-API publishes rates daily, and the app checks for updates up to twice a day, or when you tap Refresh rates in Settings.

Your subscription names, prices, notes and billing schedules are not included in that request. Like any internet request, it gives the provider network information such as your IP address, which it handles under its own terms and privacy policy. Cached and built-in rates let currency estimates work even when a refresh doesn't succeed.

Widgets and notifications

Abonné shares a snapshot of your active subscriptions with its widgets through an Apple App Group on your iPhone; it stays on your device. Home Screen and Lock Screen widgets can show subscription names, amounts and billing dates to anyone who can see your screen.

Payment reminders are optional. They're scheduled and delivered by iOS on your iPhone after you grant notification permission — no notification server is involved. You can control notification previews and permissions in the iOS Settings app.

Backups

You can export your subscriptions to a file from Settings and import a backup later. Exported files contain the subscription information described above. Where they're stored and who can see them depends on where you save them, such as in Files or with a cloud storage provider. We never receive these files.

Deleting your data

Because we don't hold your data, we can't access, correct or delete it on your behalf — you control it directly on your device.

Opening a service's website or the exchange-rate provider's website takes you outside Abonné, where those services' own privacy policies apply.

If you email us for support, we receive your email address and whatever you choose to include, and we use it only to respond to you. Please don't send backup files or sensitive financial information unless your request needs it.

Information from Apple

Apple handles App Store downloads under its own privacy policy. If you've chosen to share analytics with app developers on your iPhone, Apple may provide us with crash reports and anonymous usage statistics, which we use only to fix problems and improve the app. You can change this in Settings › Privacy & Security › Analytics & Improvements.

Children

Abonné isn't directed to children under 13, and it doesn't collect personal information from anyone.

Changes to this policy

This policy may be updated when the app's data practices change. We'll update this page and the date at the top, and mention significant changes in the app's release notes.
