Privacy Policy — SigmaQuest

Last updated: August 5, 2026

This Privacy Policy explains how SigmaQuest handles your information. We designed this app to respect your privacy.

The short version

SigmaQuest runs on your device and does not collect personal information. It offers optional in-app purchases that are processed by Apple. There is no advertising and no account.

Information we collect

None directly. We operate no servers and do not receive personal data from you. Your progress and settings are stored locally on your device.

In-app purchases

SigmaQuest may offer optional purchases (for example, to unlock content). All payments are handled by Apple through the App Store under Apple’s terms. We never see or store your payment card details. Apple provides us only with anonymized information needed to confirm a purchase and to prevent fraud.

Restoring purchases

Purchase records are tied to your Apple Account so you can restore them on your devices. This is managed by Apple, not by us.

Children's privacy

We do not knowingly collect personal information from children. Purchases require your Apple Account and any parental controls you have configured.

iCloud sync

SigmaQuest can sync your progress between your own devices using Apple’s iCloud. That data travels through your Apple account, not through us — we operate no servers and never receive it. Apple handles it under Apple’s privacy policy. You can turn this off in iOS Settings, and deleting the app removes its local copy.

Your choices & rights

Depending on where you live, you may have rights to access, correct, or delete personal information we hold about you. To make a request, email nicopetrides123@gmail.com.

Changes to this policy

We may update this policy from time to time. Material changes will be reflected here with a new “last updated” date.
