Store Listing Alignment

Checked 2026-06-30. This page was compared with the public App Store and Google Play listings. Where a store privacy or data-safety label was visible, it said the developer does not collect user data.

Accurate app behavior: Puzzles, progress, stats, widgets, watch data, reminders, and settings stay local. The 3-day trial starts locally; Apple App Store or Google Play handles only the one-time Pro unlock, restore, refund, receipt, or price display. No accounts, ads, analytics, tracking, or developer backend are used.

Plain-language summary

Rinmath collects nothing. Normal gameplay stays on your device. There are no servers, no accounts, no logins. We don’t talk to advertisers or analytics services. Rinmath includes a 3-day full-access free trial, then the one-time Rinmath Pro unlock. There is no subscription, no ads, and no tracking.

What’s stored on your device

Today’s puzzle state (which rings you’ve rotated, your move count, elapsed time, current streak, onboarding flag, color-assist preference, sound preference, preferred operation) — saved as a small local preferences blob on your device.
Lifetime solve log (date, difficulty, target, par, moves, time for each completed daily) — saved locally on your device. Used to draw your History calendar and compute the Stats dashboard. Capped at 1,024 records.
Rinmath Pro entitlement — if you unlock Pro, the app stores a local flag so Pro features remain available offline. Purchases and restores are processed by Apple or Google, depending on the store you used. Rinmath does not receive or store your payment card details.
Widget rollup — on platforms with a home-screen widget, a separate small local blob (today’s target, difficulty, current streak, solved/in-progress flag) is written so the widget can render without launching the app. This data also stays on your device.

What’s NOT collected

No name. No email. No phone number. No location. No birthdate.
No camera, microphone, photo library, or contacts access.
No advertising identifiers, including Apple advertising identifiers or the Android Advertising ID.
No analytics events. No tracking.
No crash reports sent to us. (iOS may send anonymized crash data to Apple if your device’s Diagnostics setting opts in — that’s between you and Apple.)
No third-party analytics, advertising, or tracking tools are linked into the app.

Purchases and Rinmath Pro

Rinmath Pro starts with a 3-day full-access free trial, then a one-time unlock for premium features such as Stats, full History, color assist, Solve Coach, unlimited custom puzzle creation, and the Apple Watch companion on Apple platforms. Free players can still play the daily puzzle, free-play puzzles, share solves, and play shared custom puzzle codes.

Purchases are handled by the app store you use:

On Apple platforms, Apple StoreKit processes the purchase and restore flow.
On Android, Google Play Billing processes the purchase and restore flow.

Those store services may process purchase information under their own policies. Rinmath itself has no account system and does not send purchase history, puzzle history, or personal information to any Rizk Corsight server.

Network usage

Rinmath is offline-first by design. Playing puzzles, saving progress, viewing history, and generating share text happen locally on your device. Network access is used only when the operating system or app store handles a purchase, restore, or store-managed check for Rinmath Pro.

When you tap the Share button after solving, Rinmath generates a small text “share grid” and hands it to the system share sheet. When you create a custom puzzle, Rinmath can generate a RINM- puzzle code that describes the puzzle settings, not personal information. What happens next is entirely your choice — you decide whether to copy it, send it in a message, post it, or cancel out. Rinmath itself never transmits the share text or puzzle code anywhere.

Audience

Rinmath is rated for general audiences. It is not directed to children, is not in the Kids Category on the App Store, and is not in Google Play’s Designed for Families program. If a child uses Rinmath through a family purchase or family-managed device, the same privacy posture applies — no information is collected from any user regardless of age.

Changes to this policy

If we ever change the policy, the “Last updated” date at the top will change, and the change will be summarized in store release notes for the build that introduces it.
