Controlled Collapse support

Controlled Collapse is free to download and use. It may offer optional extras, such as removing ads or unlocking premium content, as a purchase in Google Play or the App Store. The price is always shown before you buy, and you can try Controlled Collapse in your browser at apps.foxperstudios.com first.

Everything you create in Controlled Collapse is stored on your device and is not uploaded to our servers. If you allow optional services such as analytics or crash reports, they work as described in the privacy policy, which you can open from the links on this page. You can change these choices in the app's settings at any time.

If you bought something in Controlled Collapse before, you can restore it on any device that uses the same store account:

1. Sign in with the Google Play or App Store account you used to buy.
2. Open Controlled Collapse and go to Settings.
3. Tap “Restore purchases”.

If Controlled Collapse offers a subscription, it is billed and managed by the store. Cancel at least 24 hours before the current period ends to avoid the next charge:

1. On Android: Google Play → profile picture → Payments & subscriptions → Subscriptions.
2. On iPhone or iPad: Settings → your name → Subscriptions.
3. Choose Controlled Collapse and tap Cancel.

Controlled Collapse follows your device language by default. To use another language, open Controlled Collapse, go to Settings and pick one from the list; the change applies right away. The product page lists every language Controlled Collapse offers, and you can switch back to your device language in the same menu at any time.

Most problems are solved by an update. If it keeps happening, these steps help us find the cause quickly:

1. Update Controlled Collapse to the latest version and restart your device.
2. Note your device model, the app version and what you were doing when the problem happened.
