Halumo
Privacy Policy
Last updated: July 18, 2026
What stays on your Mac
Halumo opens, previews, edits, and exports your photo files locally. Your original photos, previews, recipes, edit history, presets, sidecars, and exports are not uploaded to Halumo by the editor. Halumo does not send photo pixels to its AI service.
Account information
If you sign in, Halumo receives the basic account information provided by your chosen sign-in provider, such as your name, email address, provider identity, and authentication tokens. Authentication is handled through the provider and Halumo's Supabase account service. Tokens are stored in the macOS Keychain so the app can keep you signed in.
AI preset generation
When you use AI preset generation, Halumo sends your written instruction and the editable recipe context needed to interpret that instruction to Halumo's AI proxy. The proxy forwards the request to its configured AI provider, currently Groq. Photo pixels are not included. AI usage is associated with your Halumo account to enforce the displayed allowance.
Service data and retention
Halumo's account service stores account records and the service data needed for authentication and AI allowance accounting. Halumo does not use your local photo library as a cloud photo library. Service logs and AI-provider processing are handled according to the applicable service providers' retention and privacy terms.
Deletion and sign-out
You can sign out from Settings → Account. You can permanently delete your Halumo account from the same screen. Account deletion removes the Halumo account and associated server-side account and AI-usage records. Files stored on your Mac, including photos and local edits, are not deleted by account deletion.
Changes and contact
We may update this policy when Halumo's data practices change. The version and date shown here identify the current published copy. For privacy questions or deletion problems, contact Halumo support through the contact details published with the App Store listing, or via imnotstudios.pages.dev.
