Privacy

The privacy policy of the apps that have no website of their own. Briefly: they collect nothing about you, and this site collects only what you type into the support form yourself.

The apps with their own website (SilentBox, NotaBene, SilentKey, Puťovka) have their privacy policy there.

Zombie Run

The app collects no data. It has no account, no analytics, no ads and no third-party code, and it makes no network connections of its own.

• On your iPhone only. Your progress, stars and settings are stored on the device (and in its backup). Deleting the app deletes them.
• Game Center. If you are signed in to Game Center, your escape times, stars and achievements go to Apple’s Game Center and appear on its leaderboards, under Apple’s privacy policy. Sign out of Game Center in Settings and nothing is sent.
• Crash reports. If you allowed sharing with app developers in iOS Settings ▸ Privacy & Security ▸ Analytics & Improvements, Apple may pass me anonymous crash reports. They contain no personal data.
• TestFlight. Betas run through Apple’s TestFlight. What Apple knows about testers follows its rules; what reaches me is the tester’s email address, crash reports and any feedback the tester sends.

Karkulka

The app collects no data. It has no account, no analytics, no ads and no third-party code, and it makes no network connections of its own.

• On your device only. Your settings, best score, stars, the flowers in your herbarium and the hood you wear are stored on the iPhone or iPad (and in its backup). Deleting the app deletes them.
• Game Center. If you are signed in to Game Center, your scores and achievements go to Apple’s Game Center, under Apple’s privacy policy. Sign out of Game Center in Settings and nothing is sent.
• Crash reports and TestFlight work as described for Zombie Run above.

Catch The Snake

The app collects no data. It has no account, no analytics, no ads, no Game Center and no third-party code, and it makes no network connections of its own.

• On your device only. Your progress (the moons and best move count of each level) and your settings (sound, music, haptics, reduced motion, left-handed) are stored on the iPhone or iPad (and in its backup). Deleting the app deletes them.
• Crash reports and TestFlight work as described for Zombie Run above.

This site

No analytics, no cookies, nothing loaded from other servers. When you send the support form, only what you typed is processed: your email address, the app and the message. The form is received by Netlify, the provider that serves this site. I use the address to reply and for nothing else — it is not passed on and not added to any mailing list. Ask and it is deleted.
