Privacy
Documents never leave your device.
Paperwise is a read-only document viewer. It renders every document on your phone.
Last updated 13 November 2026
What the app keeps
There is no account, no cloud library and no upload of a document, its name or its contents. Opening a document copies it into the app's private cache so it can be reopened quickly, and records its name, size, source and reading position in a list of recent documents. Both live inside the app's private storage and are removed by Clear cache in Settings. One copy is kept while a document is open.
When something can leave
A link you tap is document content. It leaves the app inside an Intent only when you confirm
it, and only after an alert shows the full destination. The receiving app contacts that host
and may attribute the visit to Paperwise. A mailto: target may be uploaded as a
synced draft by your mail app, and a tel: target may dial. Copying a selection is a
local transfer you start. No document content leaves through any other route.
Settings and these pages
Privacy policy, Terms and Support in Settings open the corresponding page on this site in
your browser. That hand-off carries the fixed address only: no document, its name, its
contents or any identifier is added. The browser also receives the launching package as an
android-app:// referrer and can attribute the visit to Paperwise. Opening a page is
an ordinary web request, so this site's hosting provider receives the request data any web
visit sends, such as your IP address and browser user agent. This site itself sets no cookies
and loads no advertising or third-party scripts.
App analytics and crash reports
Paperwise uses Firebase Analytics for anonymous usage events and Firebase Crashlytics for crash reports. Analytics receives an app instance identifier, app and device information, and automatic event names. Crash reports contain a stack trace and device state. Neither receives a document name, address, contents, MIME type, size, search term or account ID.
Both are on by default. The “Share anonymous usage and crash reports” switch in Settings turns both off immediately, deletes unsent crash reports and is remembered after a restart. Turning it back on resumes both.
Ads
Home can show ads through Google AdMob. An ad request sends Google your IP address, advertising ID, device and app information and ad interaction data. It does not include a document name, address, contents, MIME type, size or reading position. Ads are on by default. In the EEA and UK, Google’s consent form runs first and no ad is requested without consent; Settings there offers “Manage ad consent”, which reopens that form. Elsewhere ads stay on and no ad control is offered.
Screen and accessibility
This policy covers data leaving the device. It does not cover what is visible on screen: screenshots, the task switcher and accessibility services are controlled by Android and by you.
Questions
Write to support@spendwise.download or see Support. Never send the document itself: the app cannot upload it and does not need it to answer a question.
