Privacy Policy

Last updated 19 September 2026

Plumb is a puzzle game made by Sam Wessley. This policy explains what the app collects, why, and how to stop it. The short version: there are no accounts, nothing you do in the game is tied to your name, and everything the app sends can be switched off in Settings.

What the app does not collect

• No account, sign-up, email address or password.
• No name, address, phone number or contacts.
• No photos, microphone or camera access.
• No location. The app never asks for it.
• No payment details. Purchases are handled entirely by Apple, and the app never sees your card.

What the app does collect

Anonymous usage data (TelemetryDeck)

To learn which levels are too hard or too dull, the app records events such as: a level being started, finished or left unfinished, the level number, how many moves and hints it took, which puzzle mechanics that board contained, the store being opened, and a purchase completing. Each event carries the device model, operating system version and app version, plus an identifier that is hashed on your device so the same install can be counted twice without being identified.

This data is processed by TelemetryDeck, a German analytics service chosen because it is built for anonymity and does not profile users or serve advertising. You can turn it off in Settings ▸ Privacy ▸ Share anonymous usage data.

Crash reports (Sentry)

When the app crashes or freezes, a report is sent containing the technical details of the failure: what the code was doing, the device model, operating system version and app version. No personal data, screenshots or game content is included. The same Settings switch turns this off.

Advertising (Google AdMob)

The game is free, and short advertisements appear between levels after level 30. Google AdMob serves them and may collect device and usage information, including your device's advertising identifier, to choose and measure ads.

• In the European Economic Area and the UK, a consent screen appears before any ad loads, and your choice is respected. You can change it at any time from that screen when it is shown.
• On iOS, Apple asks separately whether the app may track you across other companies' apps and websites. If you decline, ads still appear but are not personalised.
• Buying Remove Ads stops all advertisements permanently, and the advertising code is not used again.

Google's handling of this data is described in How Google uses information from sites or apps that use our services.

Purchases

Remove Ads and hint packs are sold through Apple's In-App Purchase system. Apple processes the payment and tells the app only whether a purchase succeeded. Hints bought with stars involve no money and no data leaving your device.

Game Center and iCloud

If you are signed in to Game Center, achievements are reported to Apple's service under your Game Center identity, which is governed by Apple's privacy policy. Your progress is also saved to your own iCloud account so a new device picks it up. That copy belongs to you: it sits in your iCloud storage, and the developer cannot read it.

On your device

Your progress, stars, themes and settings are stored on the device itself. Deleting the app deletes them.

How to stop it

• Analytics and crash reports: Settings ▸ Privacy ▸ Share anonymous usage data.
• Personalised ads: decline Apple's tracking prompt, or change it in the iOS Settings app under Privacy & Security ▸ Tracking. In the EU and UK, use the consent screen.
• All ads: buy Remove Ads.
• Everything: delete the app.

Data sharing and retention

Nothing is sold, and no data is shared except with the services named above, each acting as a processor for the purpose described. Analytics and crash data are kept for as long as they remain useful for improving the game, and are deleted on the providers' own schedules.

Children

Plumb is suitable for all ages but is not directed at children under 13, and the developer does not knowingly collect data from them. If you believe a child's data has been collected, get in touch and it will be deleted.

Your rights

Depending on where you live, you may have the right to access, correct or delete personal data held about you, or to object to its processing. Because the app collects no name, email or account, the data described above generally cannot be traced back to an individual, which means requests to find "your" records usually cannot be fulfilled — there is nothing linking them to you. You can still stop all collection using the switches above, and you are welcome to write with any question.

Changes

If this policy changes, the date at the top changes with it, and material changes will be noted in the app's release notes.
