Terms

These terms describe the Mathnatic test release. An adult must control every account and all purchases. An account may be configured for individual practice or for multiple players.

Playing Mathnatic

Try Mathnatic is temporary guest play without saved progress. A guest may explicitly carry current guest progress into a new profile during signup. Individual accounts provide one adult-managed learning profile. Multiple-player accounts may create player profiles, choose games, use learning-level game recommendations, set child-wide learning skills, choose whether game setup appears before play, test games without saving test results, grant play time, and review progress and recent game activity. Compatible games share skill history and may use it to adapt later questions when Adaptive Practice is enabled. One Manager PIN always protects player deletion and Manager Lock changes. When Manager Lock is on, it also protects Manager View during Player Mode; when it is off, players may leave Player Mode and change settings without a PIN. Deleting a synchronized profile removes its Cloud profile and progress. Mathnatic retains only its opaque profile identifier and deletion time so an older signed-in device cannot recreate it automatically. Adult account owners are responsible for supervising use and keeping account, email, and PIN access private.

A new game may start while any granted play time remains and the current-release check passes. At zero, an active finite game may finish; Endless practice stops after its current card. Its normal result appears before the play recap. Stop playing during an unfinished game asks for confirmation and retains already-earned progress. Choosing another game keeps the current play period open. Play more from a multiple-player recap grants a new saved duration, requiring the Manager PIN when Manager Lock is on. Switching Players separates choosing a Player from the explicit action that grants and starts play. Individual and guest play do not require a Manager PIN or Player picker.

Play recaps show completed games, original questions answered, first-try accuracy, and topics actually practiced, including partial games. They show no elapsed-time metric. Signed-in Players retain their newest 30 immutable recaps in Progress. Free and Lifetime history stays on the current device; active Cloud and Complimentary Lifetime synchronize finalized history. Current play totals and a pending recap recover only on the same device after reload, without granting more time or resuming an unfinished game's individual questions. Guests have no saved recap history, and Manager Test does not change real play recaps or rewards.

Players can pause timed or Unlimited Player Mode and resume without a PIN, including when Manager Lock is on. Switching tabs or apps, locking the screen or leaving the page also pauses play. Returning waits for an explicit Resume. Pause freezes remaining play time, game input and game timers while keeping a game that is still open in the same position. It does not end the play period, grant time or award progress. Individual Account, guest and Manager Test play are unchanged.

After refresh or reopening on the same device, Player Mode stays paused with its remaining grant and already-earned progress and play totals. Resume starts a fresh round instead of restoring an unfinished board or question. Resume still requires current access, internet and the current app release, and cannot start a new round after time expires. Pause recovery stays on that device even with Cloud access and is not part of a backup. Manager View and fresh play grants retain their normal Manager Lock rules.

New first-try arithmetic practice can earn number milestone bonus points. Game results show game points and these bonuses separately; bonuses do not change accuracy or completed-game counts. Loading or importing existing progress does not grant catch-up rewards. Points are practice feedback and have no monetary value. Rewards stay temporary for guests and device-local for Free and Lifetime; active Cloud and Complimentary Lifetime access synchronize shared milestones without awarding the same milestone twice.

PIN access and recovery

A device linked over a secure connection keeps a protected PIN verifier for Manager checks during a temporary connection interruption. This does not enable offline play. Changing or recovering the PIN invalidates older device copies after they reconnect. A forgotten PIN can be replaced only after Clerk re-verifies the account owner, normally with an email code or a new sign-in.

Plans

Free access includes a growing game collection, device-local progress, one individual learning profile or up to two player profiles, global learning settings, and Manager controls. Manual backup export and import are not included with Free. Lifetime access is a one-time entitlement for premium games and expanded controls; progress remains separate on each device unless an adult exports and imports it. Cloud access is a monthly subscription that adds automatic progress syncing, new game-idea submissions, and private idea collaboration. Six successful Cloud monthly payments permanently earn Lifetime access. Complimentary Lifetime can be granted by the Mathnatic owner without payment and includes Cloud features.

Internet access and app updates

Internet access and the current Mathnatic release are required to start a new game or round on every plan, including guest play and Manager Test. Adding Mathnatic to your home screen is optional and does not add offline play. An internet connection does not require a Cloud plan; Free and Lifetime progress still stays on each device.

If a connection is interrupted or an update is found during a finite game, that game can finish and save before further play waits for the connection or update. Endless practice stops after its current card. Mathnatic applies required updates at a safe boundary after saving signed-in device data and pending Cloud changes. It does not refresh through an active game, play recap, Player picker, stopping confirmation, Manager draft or PIN flow. Guest progress is temporary and can end when an update refreshes the visit.

Existing installations move to the online app without requiring you to uninstall it, clear site storage or recreate Players. Saved device progress and pending Cloud changes are preserved during this change.

Cloud synchronization

All signed-in plans include a school-day streak, calendar, and Manager restoration controls. Weekdays count throughout the year except observed nationwide United States federal holidays and Manager-scheduled breaks. Streak dates change at 3 a.m. America/New_York time. Completing a finite game, or ten original cards in one Endless run on the same streak date, qualifies that date regardless of accuracy. An ended, missed eligible date resets the streak. Excluded dates neither advance nor reset it. A cosmetic rank badge reflects the highest consecutive school-day count earned and remains after a reset. Higher ranks require reaching their milestones in one streak, not accumulated lifetime play; badges add no points or other plan benefits.

Active Cloud and Complimentary Lifetime add a daily streak celebration and a regular-point multiplier, starting at 1x and increasing by 0.1 per consecutive eligible played date to a maximum of 2x. Fixed mastery rewards are not multiplied. New access does not reprice past points. Managers can excuse missed dates within the preceding 90 calendar days with a private reason category, or Other with a private explanation, but this does not mark those dates as played or alter past points. Administrator category percentages use only existing retained active Cloud or Complimentary Lifetime progress, without Player identities or explanation text. Basic-plan streaks and corrections stay on that device. Guest and Manager Test play do not save streaks or earn these rewards.

Mint Meadow, Midnight Grove, Berry Bloom, and Blue Steel are shared app themes selected in Manager View or Individual Account settings, alongside a shared completion-fireworks switch. Reduced-motion preferences suppress fireworks. The theme stays consistent when Players change or enter a game. Choices stay on the current device for Free and Lifetime and synchronize only with active Cloud or Complimentary Lifetime access. Guests use Mint Meadow without a saved theme choice.

Cloud-enabled play saves changes on the current device first and synchronizes accumulated changes at meaningful checkpoints, including completed rounds, leaving Player Mode, reconnecting, returning to the foreground, and a maximum regular delay of five minutes while changes are waiting. Another signed-in device may therefore see eventual rather than answer-by-answer updates. Pending changes remain on the device and retry automatically until acknowledged.

Different Players may be active on different online devices. To reduce conflicting use, the same Player normally cannot start on a second online device until the first device releases that Player or has been idle for five minutes. Paused play does not keep that activity reservation alive. Resume checks that the Player is available; if another device is using the Player, play stays paused without taking over the other device. Offline devices cannot observe one another; if rare overlap occurs, Mathnatic automatically merges completed rounds, points, practice attempts, finalized play recaps, best results, and the most recent setting changes after reconnection.

Test billing

Paid plans are currently offered only to account owners with a United States billing address. Stripe is connected in test mode. Test checkout does not buy a live entitlement and must not be treated as a real charge. Live billing will not begin until pricing, refunds, taxes, regional availability, cancellation, privacy, and support procedures are finalized.

Refunds and billing help

When live billing begins, an account owner may request a refund within 30 days of a Lifetime purchase or first Cloud charge. Later Cloud renewal charges are generally non-refundable except where required by law or when a duplicate charge or confirmed technical billing error occurred. Submit billing questions and refund requests through Support in Manager View. Mathnatic will review the account and Stripe transaction before deciding the request.

Cloud cancellation

A scheduled cancellation takes effect at the end of the paid period. Cloud data then remains read-only for 30 days. The account owner can keep a local copy or delete the cloud copy sooner. After the retention window, player profiles and progress are scheduled for deletion.

Backups

Lifetime, active Cloud, and Complimentary Lifetime accounts can use manual backup export and import. Backups are readable files containing player nicknames, settings, the shared theme and fireworks choices, favorite-game choices, and progress, including finalized play recaps, streak calendars and private restoration reasons. They do not contain the account email, sign-in credentials, billing data, or Manager PIN. Account owners should keep backup files somewhere appropriate.

Fair use

Do not attempt to disrupt the service, access another account's data, bypass paid access, submit harmful material, or use Mathnatic in a way that violates law. Active Cloud and Complimentary Lifetime accounts can choose Suggest a Game in Support and discuss the idea privately with authorized Mathnatic administrators. Ideas may be declined and do not transfer ownership or guarantee development. Existing game-idea conversations remain readable after a plan change.

Support

Signed-in account owners can contact Mathnatic through Support in Manager View, exchange private messages, and follow the request status there. Anyone can email mathnatic.support@gmail.com for support or privacy requests. Account replies reopen a request for attention; administrator replies and status changes are separate actions. Do not send passwords, Manager PINs, payment-card numbers, or unnecessary information about a minor.

Changes and availability

Games and free or premium classifications may change as the library grows. Existing paid entitlements will be handled according to the plan terms in effect when live billing begins. Test features may change or be unavailable while they are being validated.
