KeepNotes — Privacy Policy

Last updated: 26 October 2026

KeepNotes is a notes and tasks app for Android (package com.nanosolutions.keepnotes). This policy explains what data the app does and does not handle.

Your notes stay on your device

The content you create — notes, tasks, checklists, reminders, folders, tags, images, audio, local backups, and version history — is stored only in the app's private storage on your device. KeepNotes does not upload, transmit, or have any server-side access to your notes or their contents. Notes you choose to lock are additionally encrypted at rest using the Android hardware-backed Keystore and your biometrics or PIN.

Data we collect for analytics and stability

To understand how the app is used and to fix crashes, KeepNotes uses Google Firebase. This sends a limited amount of diagnostic and usage data — never your note content — to Google, which processes it on our behalf:

Firebase Analytics
Firebase Crashlytics

This data is used only to analyze usage trends, diagnose crashes, and improve the app. We do not sell it, use it for advertising, or combine it with your note content (which never leaves your device). Google processes it under Firebase's data-processing terms; see also the Google Privacy Policy.

Data sharing

The analytics and crash data above is shared with Google (Firebase) solely to provide these services. We do not share your data with any other third parties, and we never sell it.

Permissions the app uses

Data retention

Firebase retains analytics and crash data for the periods described in Google's Firebase documentation. On-device data is removed when you delete it in the app or uninstall the app.

Children

KeepNotes is a general-purpose app and is not directed at children.

Changes

If the way we handle data changes, we will update this policy and the "Last updated" date before the change takes effect.
