Sikku Privacy Policy

Effective date: August 21, 2026

Sikku does not collect, store, or transmit any personal data. Period.

• No data collection — the app has no analytics, no tracking, no advertising, and no third-party SDKs. The privacy manifest bundled with the app declares no collected data types at all, and no tracking domains.
• No accounts — there is nothing to sign up for and nothing to log in to.
• Local storage only — which levels you have solved, your best time on each, your flawless badges, and your sound and haptics preferences are saved in the app’s own storage on your device, purely so your progress survives between launches. Deleting the app deletes them.
• iCloud — if you are signed in to iCloud, that same small record of your progress syncs through your iCloud account, so a puzzle solved on your iPhone is solved on your iPad. It is held by Apple in your own private key-value storage. There is no server of ours anywhere in that path, and no way for us to read it.
• Purchases — the one-time unlock is handled entirely by Apple’s App Store. Sikku never sees your payment details, and the transaction tells us nothing about you. Whether you own the unlock is checked on your device, against the App Store, with no account and no receipt server of ours involved.
• Sound is synthesised, not recorded — every note you hear is generated on your device as you play. There are no audio files in the app, and it never uses the microphone.
• Nothing else is touched — no location, no contacts, no photos, no camera, no notifications. Sikku asks for no permissions at all.

Beyond Apple’s own iCloud and App Store, both acting for you rather than for us, Sikku makes no network connections whatsoever. Because it collects nothing, there is nothing for us to share, sell, or lose.
