Rarely Privacy Policy

No trackingNo analytics, ads or crash reports
No transferYour data stays on your phone

The short version

Rarely does not collect anything. There are no accounts, no analytics, no advertising and no tracking. The app makes no network requests, and everything it knows about you stays on your phone.

The word of the day is not fetched from a server. It is worked out from the date itself, which is why Rarely works with no connection at all — on a plane, in a tunnel, or on a phone that has never been online.

What Rarely stores on your device

Four things, all held in the app's private storage area.
What	Why it is kept
Saved words	So your bookmarks are still there next time
Practice progress	Which words you have reviewed, and when each is due again
Streak	How many days in a row you have opened the app
Settings	Your reminder time, whether reminders are on, and your theme choice

None of it is transmitted anywhere. It is not shared with the developer, and there is no server that could receive it.

What Rarely collects about you

Nothing. No name, no email address, no account, no location, no contacts, no device identifiers, no advertising ID, no usage statistics and no crash reports.

What leaves your device

Nothing that Rarely itself sends. Three things are worth naming honestly, because they involve your phone's operating system rather than the app:

Device backups. If you use Android Auto Backup or iCloud Backup, your operating system may include Rarely's stored data in its normal backup of your phone. That is a transfer between you and Google or Apple, governed by their privacy policies rather than this one. You can exclude it in your device's backup settings.
Sharing a word. When you tap Share, your phone's own share sheet opens and the word and its definition go to whichever app you choose. That happens only when you tap it, and Rarely is not told what you picked.
Nothing else. No usage data, no crash reports, no identifiers of any kind.

Notifications

If you turn on the daily reminder, notifications are scheduled locally on your phone, each one already carrying its word. There is no push server and no notification token. Nothing is sent or received when a reminder arrives. Turning reminders off in Settings cancels every scheduled notification immediately.

Widgets

The home screen widgets read their word from a storage area shared between the app and the widget on your own device. That data never leaves it, and the widget makes no network requests either.

Permissions

Rarely asks you for one permission. The installed app also declares several that Android grants automatically without asking — they come from the libraries Rarely is built with, not from features it uses, and none of them carry any data.

NotificationsYou are asked

Only if you turn on the daily reminder. You can decline, and the rest of the app works normally.

Internet and network stateAutomatic

Declared by the libraries Rarely is built with. Rarely makes no network requests.

Run at startup, wake lockAutomatic

So a pending daily reminder survives a restart.

VibrateAutomatic

The reminder's alert.

Cloud messaging, install referrer, launcher badgesAutomatic

These come from libraries pulled in alongside the notification component: Firebase Messaging, the Play install-referrer client, and a badge library. Rarely uses none of them. No push token is ever requested, and the app ships with no Firebase configuration, so the messaging service never initialises or connects.

Children

Rarely is suitable for all ages. Because it collects no data at all, it collects none from children either.

Deleting your data

Uninstalling Rarely removes everything it has stored. Settings → Reset progress clears your practice history without removing the app. Because nothing is ever sent anywhere, there is no copy elsewhere to request or delete.

Changes to this policy

If this policy changes, the updated version will be published here with a new date at the top. Any change to what Rarely collects would also mean a new version of the app — and as of this one, the answer is still nothing.
