Privacy Policy
Last updated 21 October 2026
This policy covers the Android app Solitaire (com.makuno.solitaire), classic Klondike solitaire with a daily challenge. The app is free. It may show one small banner ad and never shows pop-up or video ads between games.
We do not ask for your name, email address, phone number or location, and there is no account to create. Your games, statistics and settings stay on your device.
What stays on your device
The deals ship inside the app and every game works without internet. Your game in progress, your statistics, levels, daily challenge cups and settings are stored only on your device (and in your phone's own backup, if you have it turned on).
What we collect
| Data | Why |
|---|---|
| Advertising ID (Google Advertising ID) |
So our advertising partners can show relevant ads, cap how often you see the same ad, and measure whether an ad worked. You can reset or delete it at any time — see below. |
| Android ID and an app install ID | To count how many people play and recognise a returning device, without an account. |
| Device and technical information device model, operating system, language, country, screen size, network type, battery level, app version |
To make the app work correctly on your device, to fix problems, and because our advertising partners need it to serve an ad. |
| Usage events app opened, how long it was on screen, how fast it started, screens viewed, games started, won or lost (the deal, difficulty, time, moves, score, undos and hints), daily challenges, levels reached, settings changed, menu items tapped, and your answer to the daily reminder question |
To understand how the game is played, to make deals and difficulty fair, and to make the app better. |
| Crash and error reports how the app last closed (a crash, a freeze, low memory), errors the app caught, device model, operating system, app version |
To find and fix crashes. |
We do not collect your name, email, phone number, precise location, contacts, photos or files.
Country comes from your SIM card, your mobile network and the internet address your phone connects from. We work out the country from that address on arrival and do not store the address itself.
Permissions
- Internet and network state — to send usage events and crash reports, to load ads, and to know when you are offline. Playing works without internet.
- Notifications — only if you turn on the daily challenge reminder, once a day.
- Advertising ID — see Advertising below.
Advertising
The app may show one small banner ad on the game screen. Ads are supplied by advertising partners who may collect and use device information — including your advertising ID — to select, deliver and measure ads. Each partner has its own privacy policy:
- Unity LevelPlay (ironSource) and Unity Ads — unity.com/legal/game-player-and-app-user-privacy-policy
Where the law requires your consent before personalised advertising, the app asks for it through Google's consent form (policies.google.com/privacy) before any ad is requested, and you can change your choice later in the app's menu.
Your choices
You can reset or delete your advertising ID at any time, which stops it being used to build a profile of your interests:
- Android — Settings → Google → Ads → Reset advertising ID or Delete advertising ID
Deleting it does not remove ads; it makes them less relevant. You can turn the daily reminder off at any time in the app's settings.
Analytics and crash reports
Usage events and crash reports are sent to servers we operate ourselves, not to a third party. They are tied to the device identifiers described above, not to you personally, and we never sell them.
Children
The app is a card game for a general audience and is not directed to children. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, contact us and we will delete it.
How long we keep data
Your games and settings stay on your device until you uninstall the app. Usage events and crash reports are kept for as long as they help us improve the app, and deleted on request. Advertising partners keep data according to their own policies, linked above.
Deleting your data
Uninstalling the app removes its data from your device. To have the usage events associated with your device deleted from our servers, email us at the address below and we will remove them.
Security
We use reasonable measures to protect the data we hold. No method of transmission or storage is completely secure, and we cannot guarantee absolute security.
Changes
We may update this policy. The date at the top shows when it last changed. Continued use of the app after a change means you accept the updated policy.
