Privacy Policy

Last updated: June 2026

Wisera Games ("we", "us") makes logic puzzle apps including Hashi and Slitherlink. This policy explains what data the apps collect and how it is used. We keep data collection to the minimum needed to run the games and improve them.

Information we collect

  • Game progress — your levels, stars, streaks and settings are stored locally on your device. We do not upload or store this on our servers.
  • Anonymous usage analytics — aggregated, non-identifying events (e.g. a level was completed, an ad was shown) help us understand how the games are played.
  • Advertising data — our ad provider may use device identifiers to serve and measure ads.
  • Purchase status — if you buy the "remove ads" option, our payments provider records that entitlement. We never see or store your card details.

Third-party services

The apps use these services, each with its own policy:

How we use information

To run the games, show and measure ads, process the optional ad-removal purchase, fix bugs, and improve gameplay. We do not sell your personal data.

Children's privacy

Our games are family-friendly. We do not knowingly collect personal information from children, and ads are configured to be age-appropriate where required by the app stores.

Your choices

  • Limit or reset ad personalization in your device settings.
  • Buy "remove ads" to turn off interstitial advertising.
  • Uninstalling an app removes all locally stored progress.

Data retention & security

Progress lives on your device until you clear it or uninstall. Analytics and advertising data are retained by the respective providers per their policies.

Changes

We may update this policy as the apps evolve. Material changes will be reflected here with a new "last updated" date.
