QSum Privacy Policy

Effective: July 2026 · Published by PIXIE LAB STUDIOS LLC

Data the app itself collects

None. QSum has no accounts, no sign-in, no analytics of its own, and no backend operated by us. Your level progress, streaks, hints, and settings are stored only on your device and never leave it. Uninstalling the app deletes them.

Advertising

QSum shows optional, rewarded video ads served by Google AdMob — they only play when you choose to watch one in exchange for an in-game reward. To serve and measure ads, Google may collect device information such as your advertising ID, IP address, and coarse device data, as described inGoogle's Privacy Policy andAdMob's partner documentation. You can reset or delete your advertising ID in your device's Google settings. We do not receive or store any of this data ourselves.

In-app purchases

Purchases (such as hint packs) are processed entirely by Google Play. We receive anonymized order information from Google to deliver what you bought, and no payment details ever reach us.

Children

QSum is a general-audience app and is not directed at children under 13. We do not knowingly collect personal information from children.

Changes & contact

If this policy changes, we will update this page before the change ships. Questions: pixielabstudios94@gmail.com.
