Gestalt is designed with your privacy in mind. Here's how the app handles your data.
Gestalt has no user accounts, and uses no analytics, tracking, or advertising frameworks. We don't build a profile of you. If you subscribe, your images pass through Gestalt's captioning service on the way to be described, as explained below — nothing is kept there.
When you use Gestalt to generate alt text, your image is sent away to be described and a caption comes back. Where it goes depends on how you’re using the app.
If you subscribe: your image goes to Gestalt’s captioning service, which checks that your subscription is active and then passes the image to Anthropic to be described. The service doesn’t store your images, your captions, or any record of what you captioned — each request is handled and then discarded. To confirm you’re entitled to use it, your device also sends a subscription receipt issued by Apple. That receipt identifies the purchase, not you, and it isn’t stored either.
If you use your own API key: your image goes directly from your device to the provider you chose (Anthropic or OpenAI). It doesn’t pass through Gestalt’s service at all.
Either way, images are sent solely so they can be described, and are not stored by Gestalt. Please refer to Anthropic’s privacy policy and OpenAI’s privacy policy for details on how they handle data sent to their APIs.
If you use the "Bring Your Own Key" option, your API key is stored securely on your device. It is never sent to Gestalt’s captioning service, and never shared with any third party other than the AI provider you selected.
Gestalt Premium subscriptions are processed entirely by Apple through the App Store. Gestalt does not collect or have access to your payment information. Apple may share subscription status information with Gestalt to provide you with access to premium features. See Apple's privacy policy for details.
Gestalt stores the following information locally on your device:
This data stays on your device. The one exception is your caption length preference, which is sent with each request so the description comes back the length you asked for.
If this policy changes, the updated version will be posted here with a new effective date.
