Vitae

Vitae is a local-first nutrition logging app. We do not operate a server, create user accounts, sell data, run ads, or collect analytics from the app.

Short version: your profile, nutrition targets, food logs, saved foods, settings, AI request logs, and API keys stay on your device unless you choose to export them, enable an Apple-provided sync or backup feature, or send a specific photo or meal description to an AI provider you configure.

Scope

This Privacy Policy describes how the Vitae iOS app handles information. It is intended to support the privacy disclosures required for App Store distribution and to explain Vitae's actual app behavior in plain language.

Effective date: May 29, 2026.

Data We Do Not Collect

The Vitae developer does not collect personal data from the app. Vitae does not include developer-operated analytics, advertising trackers, third-party ad SDKs, account registration, push notification tracking, or a developer-hosted backend service.

Because the developer does not receive app data, we do not use your data for advertising, marketing, profiling, analytics, resale, or tracking across apps and websites.

Information Stored Locally

Vitae stores the information needed to provide nutrition tracking features on your device using iOS local storage and Keychain.

Information	How Vitae Uses It	Where It Is Stored
Profile and targets	Display name, calorie target, protein target, optional carb, net carb, fiber-related, and fat preferences are used to personalize nutrition totals and progress views.	On your device.
Food logs and saved foods	Food names, meal times, serving descriptions, calories, protein, carbs, fiber, sugar alcohols, fat, notes, favorites, source type, and timestamps are used to show logs, saved foods, and statistics.	On your device.
AI settings and logs	Selected AI provider, model choice, request status, prompts, input summaries, provider name, model name, results, warnings, and errors are stored so you can review prior AI analysis requests.	On your device.
AI provider API keys	API keys you enter for OpenAI, Google Gemini, or xAI are used only to make requests you initiate to that provider.	In Apple Keychain on your device. API keys are not included in Vitae JSON exports.
Photos selected for AI analysis	A selected nutrition label or meal photo can be sent to your chosen AI provider only when you ask Vitae to analyze it.	The photo itself is not kept by Vitae as a separate photo library. A local AI log may keep request details and analysis output.

Optional AI Provider Requests

Vitae can request nutrition estimates from AI providers when you choose to use AI features. These features are optional and require you to provide your own API key for the provider you select.

When you start an AI analysis, Vitae sends the specific content needed for that request directly from your device to the selected provider. This may include a meal description you typed, a nutrition label photo, a meal photo, prompt instructions, your net-carb preference, your selected model, and your provider API key for authentication.

The Vitae developer does not receive these AI requests or responses. The selected AI provider may process, store, retain, or use request data according to its own terms, privacy policy, API data processing terms, account settings, and legal obligations. Those practices may differ from Vitae's local-first approach.

You can avoid sending information to AI providers by not using the AI analysis features. You can remove stored API keys in Vitae's AI settings.

Camera and Photo Access

Vitae asks for camera access only so you can scan nutrition labels or meal photos. Vitae also uses Apple's photo picker so you can choose specific images for analysis. Vitae does not request access to your full photo library for developer collection, and it does not upload photos unless you explicitly start an AI analysis request.

Exports, Sync, and Backups

Vitae can create a JSON backup at your request. That export can include your profile, settings, saved foods, and food log entries. It does not include AI provider API keys. Once you export or share a backup file, you control where that file goes and who can access it.

Information stored on your device may also be included in Apple device backups or Apple-provided sync services depending on your iOS settings and any sync options you enable. Apple handles those services under Apple's own privacy terms.

Retention and Deletion

Vitae keeps local app data until you edit it, delete it, export it elsewhere, or remove the app from your device. You can delete food logs, saved foods, API keys, and other app content through app controls where available. You can also delete all local Vitae data by deleting the app from your device.

Because the Vitae developer does not collect or host your app data, there is no developer server account to delete and no server-side Vitae data deletion request to process.

For information sent to an AI provider, use that provider's privacy tools, account settings, or support channels to exercise any rights that may apply to data processed by that provider.

Children's Privacy

Vitae is not directed to children and does not knowingly collect personal information from children. Since the Vitae developer does not collect app data, we do not knowingly maintain personal information from children on developer systems.

Security

Vitae uses Apple platform storage, including Keychain for AI provider API keys. No storage method is perfect, so you should protect your device with a passcode, Face ID, Touch ID, and current iOS updates.

Changes to This Policy

If Vitae's privacy practices change, this page will be updated with a new effective date. App Store privacy disclosures should also be kept consistent with the app version then available.
