Privacy policy

Last updated: 3 November 2026

In short

PuzzleShelf keeps everything you enter on your own phone. There is no account, the app has no access to the internet, and nothing is sent to us or to anyone else. We cannot see your catalogue.

Who is responsible

PuzzleShelf is published by Adrian Overdijk under the name Apps With Manners. Questions about this policy can be sent to info@appswithmanners.com.

What the app keeps, and where

PuzzleShelf keeps what you enter or choose yourself:

• the details of your puzzles, such as title, brand, series, piece count, barcode, price, rating, difficulty, puzzle time and notes
• the photos you take or choose
• your settings, such as colour, light or dark and the layout of the list

All of this is kept only on your phone, in the app's own storage, which other apps cannot reach. When the app reads the text on a box, that also happens on your phone itself; the photo goes nowhere.

What the app does not do

• The app does not ask for an account, a name or an email address.
• The app has no permission to use the internet, so it cannot send data anywhere.
• The app contains no ads, no analytics and no trackers.
• The app does not share or sell data. We have no data to share.
• The app is excluded from Android's automatic backup. Your catalogue is not copied to a cloud account unless you do so yourself.

Permissions

• Camera: for photos of the box and for scanning barcodes. The app asks for it the first time you use the camera.
• Notifications: for a notification with a pause button while a puzzle timer runs. The app asks for it the first time you start a timer.
• Starting after your phone restarts: so that the notification of a running timer comes back after a restart.

Choosing a picture from your phone goes through Android's photo picker. The app only sees the pictures you choose there.

Backup, sharing and printing

• A backup is one file with all your puzzles, photos and times, which you save where you choose. The file is not protected: whoever gets hold of it can see your catalogue.
• When sharing, you choose the app that sends the photos and details of a puzzle.
• Printing your wishlist goes through Android's print function.

Once something is outside the app, for example with a cloud storage service or in another app, the terms and privacy policy of that service or app apply to it.

Deleting your data

Deleting a puzzle in the app also deletes its photos. Removing the app from your phone erases everything. Backups you saved yourself are not removed this way; you delete those where you saved them.

This website

This website uses no cookies, no analytics and no trackers, and loads nothing from other websites. The site is hosted by Cloudflare. As with any website, the host processes technical data to show the page, such as your IP address. We do not look at or keep that data ourselves.

If you send us an email, we use your email address and your message only to reply to you and, if it is feedback, to improve the app.

If this policy changes, the new version will be on this page, with a new date.
