Quick Note – Privacy Policy

Developer: Paul Studio

Effective date: October 27, 2026 · App: Quick Note (package com.paulstudio007.quicknote) · 


In short: Quick Note works offline. It has no account, no ads, no analytics and no internet permission. Your notes stay on your device. We do not collect, receive, sell or share your personal data.


1. Who we are

Quick Note is published by Paul Studio. You can contact us at dev.paulstudio@gmail.com.


2. Data we collect

None. The app does not send any data to us or to any third party, and it does not contain advertising, analytics or tracking tools. The app does not request the internet permission, so it cannot upload your notes by itself.


3. Data stored on your device

Your notes (titles, text, checklists, labels, colors, reminder times and settings) are stored only in the app's private storage on your phone. Other apps cannot read them. When you uninstall the app, this data is deleted by Android.


4. Locked notes

If you lock a note, its content is encrypted on your device using a key kept in the Android Keystore, and you must unlock it with your fingerprint, face or screen lock. The app uses Android's system dialog for this; it never sees or stores your biometric data. The title of a locked note remains visible in the note list.


5. Permissions

Notifications: used only to show the reminders you set. You can decline this permission; the app still works.

Biometric / screen lock: used only through Android's system prompt to open locked notes.

The app does not use your location, contacts, microphone, camera, or storage permissions. Files you back up, import or export are chosen by you with Android's system file picker.


6. Backups, imports and exports

You can save a backup file, export notes as text or Markdown, or import notes (for example from a Google Keep export). These files are created on your device in the location you choose. We have no access to them. Please note that a manual backup file contains locked notes as plain text, so keep backup files somewhere private. If you share a note with another app, that app's own privacy policy applies to the shared content.


The note database is excluded from Google's cloud backup of app data.


7. Feedback emails

If you use "Send feedback" in Settings, the app opens your email app with a draft addressed to us. The draft contains the app version, your Android version, your phone model and language, and whatever you write. You can edit or delete any of this before you send it. Nothing is sent unless you press send. We use the message only to answer you and to improve the app, and we do not share it.


8. Google Play

The app is distributed through Google Play. Google may provide us with aggregated, anonymous statistics (for example install counts and crash reports from users who chose to share diagnostics with Google). This is handled by Google under Google's Privacy Policy; the app itself does not send us this information.


9. Third parties

Quick Note contains no third-party advertising, analytics or tracking services, and we do not share data with anyone.


10. Children

The app is not directed at children under 13 and we do not knowingly collect any information from anyone, including children.


11. Retention and deleting your data

Your data stays on your device until you delete it. You can delete a single note (move it to the trash and delete it forever, or empty the trash), or delete everything by uninstalling the app or by clearing its storage in Android Settings. Notes in the trash are removed automatically after 30 days. Because we hold no copy of your data, we cannot recover it for you; keep your own backup if you need one.


12. Your rights

Because we do not collect or hold your personal data, there is nothing for us to access, correct, export or erase on our side. If you are in the EU/EEA, the UK, California or elsewhere with privacy rights, you may still contact us at the address above with any question and we will answer it.


13. Security

Your notes never leave your device unless you choose to back up, export or share them. Locked notes are additionally encrypted as described in section 4. No method of storage is perfectly secure, so please protect your phone with a screen lock.


14. Changes to this policy

If a future version of the app handles data differently (for example, an optional feature that you set up to sync files), we will update this page and the effective date above before that version is released.
