Effective date: March 18, 2025
Wallter has no accounts, no analytics, and no tracking of any kind. Everything stays on your device.
Wallter does not collect, store, or transmit any personally identifiable information (PII). We do not ask for your name, email address, phone number, or any other personal detail. There are no user accounts.
Projects you create — including project names, descriptions, settings, and generated images — are stored exclusively in your device's local storage using Apple's standard UserDefaults. This data never leaves your device through us and is not backed up to any Wallter server.
We do not integrate any third-party analytics SDKs (such as Firebase, Mixpanel, Amplitude, or similar). We do not track app usage, screens visited, buttons tapped, or session durations.
When you generate an image, the descriptive prompt you compose through the wizard is sent to NVIDIA NIM's image generation API (Black Forest Labs FLUX model). Only the prompt text is transmitted — no device identifiers, no location data, and no personal information. NVIDIA's own privacy policy applies to data processed on their servers. We encourage you to review it at nvidia.com/privacy.
Wallter contains no advertisements and no advertising SDKs. Your data is never sold to or shared with advertising networks.
Wallter does not request access to your camera or photo library to operate. If a future version adds the ability to save images to your Camera Roll, we will ask for your explicit permission at that time and will clearly explain why.
We do not request or use your device location in any way.
Because no data is transmitted to our servers and no accounts exist, there is no Wallter-side database that could be breached. The security of data stored locally on your device is governed by iOS's built-in security mechanisms.
Wallter does not knowingly collect any information from children under the age of 13. The app does not contain content directed at children and does not require age verification because no data is collected from any user.
If we make material changes to this privacy policy, we will update the effective date at the top of this page and, where appropriate, notify users through an in-app message. Continued use of the app after any change constitutes acceptance of the updated policy.
