Kumo: Spider Solitaire

Privacy Policy

Effective 10 November 2026, last updated 10 November 2026

In short: Kumo has no accounts, no ads, no analytics and no tracking, and it doesn't use the internet. We don't collect, sell or share your personal data. Your games, stats and settings stay on your phone.

Who we are

Kumo ("the app", "we") is a spider solitaire game for Android, with Canvas Travel Club. For any question about this policy or your data, write to [email protected].

What stays on your phone

  • Settings, stats, the game in progress and your player name. Stored only in the app on your phone. If you use Android's backup, Android may include them in your own Google backup, under Google's privacy policy; we can't see it.
  • Your 1 vs 1 record. Kumo keeps your 1 vs 1 results to show them in the app. They stay on the phone.

Your own backup

In Your data › Back up, Kumo writes one file with your data, encrypted, and you choose where to save it through Android's file picker (for example Google Drive or Downloads). We never upload it and never see it. Restore reads the file back the same way, from the place you pick. Kumo doesn't need any permission to your files or storage for this: the file picker hands over only the file you choose.

No internet

Kumo plays fully offline, and the app from Google Play has no permission to use the internet. The links on the About page (Canvas Travel Club and the other apps) open in your browser, only if you tap them.

1 vs 1 over Bluetooth

To play with a friend next to you, Kumo connects the two phones directly over Bluetooth, without the internet. Nothing goes through our servers. During a match the phones send each other the player's name (or the phone's name, if you haven't set one), the mode and the deal number, how each player is doing (stacks done, moves, deals left and score), a restart, a give up, a draw request and its answer, and the time to clear the deal.

Kumo asks for the Nearby devices permission only when you start a 1 vs 1, to find and connect to your friend's phone. It does not use Bluetooth to find your location.

Permissions

  • Nearby devices (Bluetooth): to find, connect to and be visible to a friend's phone in 1 vs 1.
  • Vibration: light taps while you play (you can turn them off in Options › Vibration).

Kumo doesn't ask for your photos, camera, contacts or location.

Test versions

Kumo Dev, the test version used by the developers and testers (not the one on Google Play), can also check our server (updates.mhitra.com) for a newer version and install it, when you tap Check for updates. It sends no personal data; like any website, the server sees your device's IP address while it answers and may keep it briefly in standard server logs.

Children

Kumo isn't directed at children under 13, and we don't knowingly collect anyone's personal data, of any age.

Other websites

The app links to the Canvas Travel Club website and to the pages of our other apps. Those sites have their own privacy policies.

Deleting your data

Everything Kumo keeps is on your phone. To delete it, clear the app's storage in Android's settings, or uninstall Kumo. A backup file you saved stays where you put it: delete it there.

Changes

If this policy changes, we'll update this page and its date. Big changes will also be noted in the app's release notes on Google Play.
