Woodturning Ultra Smooth 3D

Privacy Policy

Last updated: 14 October 2026 (version 1.2.0)
Applies to the Android app Woodturning Ultra Smooth 3D (com.canalgrid.WoodUltraSmooth3D)

1. Who we are

Woodturning Ultra Smooth 3D is developed and published by Canal Grid ("we", "us"). This policy explains what the app does with data, and what it deliberately does not do.

2. What is stored on your device

The game saves the following in its own app storage on your device. None of it is sent to us, and we cannot read it.

• Your stars and best score for each level, and which levels are unlocked
• Your Collection: the shape and colours of your best piece for each level
• My Works: pieces you made in Free Turn, and the names you gave them
• Coins, gems and wood, and the tools, axes, woods, paints and patterns you have unlocked
• Your chisel grip set-up, and the dates of daily gifts you have claimed
• Settings: sound, vibration, graphics options, and the carving outline and reference picture
• Whether Remove Ads has been bought, and whether notification permission has been asked

Deleting it is simple: uninstalling the app removes all of it permanently. We keep no copy on any server. See Delete your data.

3. What we do not collect

• No account, login or registration of any kind
• No name, email address, phone number or contacts
• No access to your camera, microphone, photo library or location
• No analytics or crash-reporting service of our own
• No sale of personal information to anyone, ever

4. Advertising (Google AdMob)

The free version shows ads served by Google AdMob: a banner on some menu screens, an occasional full-screen ad between levels or when you return to the app, and rewarded videos that you choose to watch for a bonus (for example coins in the shop). Watching a rewarded video is always optional.

To show and measure ads, and to prevent ad fraud, Google AdMob may collect and process:

• your device's advertising ID
• your IP address, and the approximate location derived from it
• device and app information, such as model, Android version, language and app version
• how you interact with the ads (views and taps)

This processing is done by Google, not by us, and we never receive this data. It is governed by Google's own policies:

• Google Privacy Policy
• How Google uses information from apps that use its services
• How Google uses advertising data

Consent and your ad choices

• EEA, UK and Switzerland: the first time you open the game, Google's consent form asks whether ads may be personalised. You can change your answer at any time with Settings → Privacy Options inside the game.
• Everywhere: you can reset or delete your advertising ID in your Android settings under Privacy → Ads (wording varies by device). Without it, ads are not personalised.
• Remove Ads: buying Remove Ads in the game stops ads from being requested at all.

5. Purchases (Google Play)

The only purchase is Remove Ads, a one-time product sold through Google Play Billing. We never see your card number, billing address or any other payment detail. The app only learns that Remove Ads was bought, and checks this with Google Play each time it starts so the purchase keeps working. If it does not show up, tap Restore Purchase in the game's Settings. Refunds and purchase history are handled by Google under the Google Privacy Policy.

6. Sharing your pieces

When you tap Share in the Collection, the game draws a picture of your piece on your device and opens Android's share sheet. The picture only goes where you send it, to the app and people you choose. It is not uploaded to us. A temporary copy sits in the app's cache folder, which Android clears and which is removed when you uninstall.

7. Reminder notifications

If you own Remove Ads, the game can remind you once a day that your free wood is ready. The reminder is scheduled on your device; nothing is sent from a server. On Android 13 and later you are asked for notification permission once. Declining costs you nothing, and you can turn it off at any time in your Android notification settings.

8. Children

Woodturning Ultra Smooth 3D is a relaxing craft game for a general audience. We do not knowingly collect personal information from anyone, including children. Ads are subject to Google AdMob's policies on ad content. If you believe a child has provided personal information through the app, please contact us.
