Keep your next intersection within reach.

1. Open the published INTERSECT address in a supported browser while online.
2. Open the browser menu and choose Install app or Add to Home Screen. On iPhone or iPad, use Safari's Share menu and choose Add to Home Screen.
3. Launch INTERSECT from the new app or home-screen icon.

If no install option appears, finish loading the game, confirm that you are using its secure published address, then check your browser's site or app menu again. You can still play in a normal browser tab without installing.

Load INTERSECT successfully once while online so the browser can cache the game. After that, the installed app or same browser address should open without a connection while its cached files remain available.

A connection is still needed for the first load and for receiving new versions. Browsers may remove cached files to reclaim storage, and private-browsing sessions are not reliable for offline use or progress retention.

Where it lives

In site storage for the current browser profile and published address.

What it includes

Gameplay, profile, Daily results, unlocks, achievements, and settings.

Cloud backup

None currently. INTERSECT has no account or cross-device synchronization.

Use the same browser profile and site address to continue. Progress will not automatically move between browsers or devices. Clearing storage, uninstalling the PWA, or losing the device can permanently remove it.

Reset gameplay and profile

1. Open INTERSECT and select the Settings control.
2. Select Reset Local Progress.
3. Select Confirm Reset.

This cannot be undone because no server backup currently exists.

Remove settings and cached files too

Clear INTERSECT's site data in your browser settings or uninstall the PWA. Browser menu names vary by platform. Removing all site data returns the next visit to a clean local installation after the game loads again.

Delete data stored on this device

Use Settings > Reset Local Progress to delete gameplay, profile, Daily results, unlocks, achievements, and preferences stored by INTERSECT on the device. Uninstalling the Android app removes its remaining local app data. Callidus Apps cannot delete this information remotely because it is not sent to us.

Request deletion of purchase-service data

1. Email callidusapps@gmail.com with the subject INTERSECT data deletion request.
2. If the request concerns a purchase, include the Google Play order number. Do not include payment-card details.
3. Callidus Apps will verify the request and confirm when deletion is complete.

For Android purchases, a deletion request covers customer identifiers and the purchase-history copy held by Callidus Apps or RevenueCat. Transaction records required for tax, accounting, fraud prevention, dispute resolution, or other legal obligations may be retained for the period required by law. Google may retain Google Play transaction records under its own policies.

The game does not open offline

Reconnect, open INTERSECT, and wait for the game to finish loading before trying again offline. Check that your browser is allowed to store site data and that you are using the same published address.

Progress appears to be missing

Confirm that you are in the same browser profile, not in private mode, and at the exact same site address. Locally cleared data cannot currently be recovered.

A new version is not visible

Go online, fully close the installed app or tab, then reopen it. A normal browser reload may also allow the cached application to update.

Sound, vibration, motion, or text needs adjustment

Open Settings to change sound effects, haptics, reduced motion, contrast, larger text, and theme options. Device and browser support for sound and vibration varies.

Daily reminders do not arrive

Reminders exist only in the Android app. Check that Daily reminder is on in Settings and that notifications are allowed for INTERSECT in Android settings. Android may deliver a reminder a little after the chosen time to save battery. Reminders are skipped on days you have already played and stop after a week without opening the app.

Include your device type, browser, whether INTERSECT is installed, and the steps that led to the issue.

For information about local data, read Privacy. The rules for using the game are in the Terms.
