Klaverjas

About the app

Klaverjas is a quiet, beautifully designed solo version of the Dutch trick-taking card game. Sixteen rounds, three computer opponents, three AI levels, Amsterdams or Rotterdams rules.

No accounts. No advertisements. No analytics. Whatever you do in the app stays on your device (and, if you have iCloud enabled, in your own iCloud account).

Privacy policy

Last updated: 28 April 2026

Short version

The app does not collect, transmit, or share any personal information. Everything you do in the app stays on your device.

What is stored on your device

The following is saved locally in iOS local-storage for the app:

• The name you entered during onboarding (used only to label your seat at the table).
• Your in-game preferences: language, table colour, card style, hand layout, AI difficulty, game-rules variant, haptic feedback on/off.
• Your game progress: the active save game, statistics (games played, win rate, average score, favourite trump suit, top 5 scores), and your position in the optional Klaverjas Academy lessons.

This data never leaves your device. The app contains no analytics SDKs, no advertising SDKs, and no crash-reporting services. It does not have a user account system, login, or any backend server.

You can erase all of this data at any time by deleting the app, or by using the “Reset” option in Settings → Statistics.

iCloud sync

If you are signed into iCloud on your device, the items listed above (your name, preferences, game progress, statistics, and Academy progress) are synchronized via Apple’s standard iCloud Key-Value Storage mechanism. This is what allows your saved game to follow you when you switch to a new iPhone or reinstall the app.

This data lives in your own iCloud account. It is not sent to us, and we do not have any way to read, see, or download it. If you sign out of iCloud, or disable iCloud for this app under Settings → Apple ID → iCloud → Apps Using iCloud, the synchronization stops and the app falls back to local-only storage.

Network usage

The app does not contact any server we operate. We have no backend. All code, fonts, and assets are bundled into the app at build time.

The only network traffic the app initiates indirectly is through Apple’s own iCloud framework (iCloud Key-Value Storage, see above), which talks to your own iCloud account. We have no visibility into that traffic and no control over it; it is governed by Apple’s own iCloud privacy policy.

Tracking and identifiers

The app does not use:

• The Identifier for Advertisers (IDFA)
• Any advertising or attribution SDK
• Any cross-app or cross-device tracking
• Any analytics, telemetry, or crash-reporting service
• Any user accounts or login

We have no way to identify or contact individual users, and we collect no information about how you use the app.

Information shared with third parties

None. No data is shared with anyone — including us. The App Store itself collects standard information when you download an app, which is governed by Apple’s own privacy policy.

Children

The app is suitable for all ages and is rated 4+ on the App Store. It does not request any personal information from any user, regardless of age.

Changes to this policy

If this policy is ever updated, the new version will be published at the same URL with a new “Last updated” date.
