Authorization and Activation

In order to prevent commercial account sharing and other piracy activities, Stash currently limits the number of devices that can use each purchase license.

iOS

Each Stash for iOS authorization is limited to a maximum of 6 devices, including iOS, iPadOS, and macOS (Apple silicon). You can view activated devices and deactivate unused devices in "Tools - System Information" (Stash V2) or "Settings - Diagnostics" (Stash V1).

Unable to activate Stash through TestFlight?

Since the AppStore receipt purchase certificate is only stored in the Stash downloaded through the store. If you are deactivated by another device during the TestFlight process or cannot connect to the activation server for a long time, this prompt may appear.

You can re-download the official version of Stash through the AppStore to cover and activate it. After successful activation, you can upgrade to the TestFlight version if needed.

macOS

Each Stash for macOS Personal Edition can be used on a maximum of 3 devices simultaneously, while Family & LifeTime Edition can be used on a maximum of 6 devices simultaneously. You can view activated devices and deactivate unused devices in "Control Panel - Settings - Authorization".

Stash is Corrupted?

Some antivirus or cleaning software may cause Stash for macOS to not run or activate properly. Please ensure that you are not using such software to block or clean Stash for macOS. If Stash is cleaned, this prompt may appear.

You can click here (opens in a new tab) to re-download and cover Stash for macOS to fix this issue.

If you encounter the prompt "Activation server refused, reached the maximum number of devices" and confirm that the number of activated devices has not exceeded the limit, please contact Stash Customer Service (opens in a new tab) on Telegram or send an email to [email protected] to explain the situation. We will resolve it as soon as possible.
