Sazón Vital Privacy Policy
In short
- Sazón Vital keeps your information on your device. Some data leaves your device only for the features described under “What leaves your device”, and only when you use them.
- No tracking and no ads. Sazón Vital doesn’t track you across other companies’ apps or websites and doesn’t show ads.
- No analytics or crash-reporting services are built in.
- No account: you don’t sign in, and we don’t know who you are.
- Purchases are handled by Apple. We never see your payment details.
Who we are
Sazón Vital is published by Marketgence Technologies LLC (“we”, “us”). This policy explains what happens to your information when you use Sazón Vital on your iPhone or iPad. Questions: support@marketgence.com.
What stays on your device
Sazón Vital keeps these on your device, in the app’s own storage that other apps can’t read:
- Your first name, servings, pantry, shopping list, weekly plan, favorites and saved recipes.
- The health conditions you mark in “Mi salud” and the ingredients you exclude.
- Your recipe feedback (for example too spicy or make again).
- A copy of your Sous Chef conversation (the latest 60 messages).
- Recipes the Sous Chef creates for you, and their pictures, in the app's files.
- How many free new recipes you've created today.
- This install's App Attest key ID; the key itself stays in your iPhone's Secure Enclave.
- Voice clips only in a temporary file until they're turned into text, then deleted.
- Copies of saved data the app couldn't read, kept aside until you erase your data in “Tus datos”.
We don’t receive this information and can’t see it.
Like other app data, it may be included in your device backups (iCloud Backup or a computer backup) if you use them.
What leaves your device
| What | Why | Sent to | When | Linked to you |
|---|---|---|---|---|
| Your Sous Chef conversation: the latest 12 messages, yours and its replies | To answer you | Our AI proxy (Cloudflare Workers), then the Vercel AI Gateway, then Google Gemini (OpenAI if Google doesn't answer) | When you use the Sous Chef chat | No |
| Health conditions you mark in “Mi salud” (for example diabetes or high blood pressure) | To adapt recipes and Sous Chef advice to them | Our AI proxy (Cloudflare Workers), then the Vercel AI Gateway, then Google Gemini (OpenAI if Google doesn't answer) | With Sous Chef messages and recipe requests while you have conditions marked | No |
| Kitchen details sent with requests: excluded ingredients, pantry items, shopping list, weekly plan, servings and tastes saved from your recipe feedback | To personalize Sous Chef answers and recipes | Our AI proxy (Cloudflare Workers), then the Vercel AI Gateway, then Google Gemini (OpenAI if Google doesn't answer) | With Sous Chef messages and recipe requests | No |
| Recipe requests (the ingredients, meal type and servings you choose) and the recipes made from them, which the AI also checks; for the picture, the recipe's title and main ingredients | To create, check and illustrate the recipe, which is then saved only on your phone | Our AI proxy (Cloudflare Workers), then the Vercel AI Gateway, then Google Gemini (OpenAI if Google doesn't answer) | When you ask for a new recipe | No |
| Photos of your fridge or pantry, made smaller (up to 180 KB) before they're sent | To list the ingredients the photo shows | Our AI proxy (Cloudflare Workers), then the Vercel AI Gateway, then Google Gemini (OpenAI if Google doesn't answer) | Only when you take or choose a photo in the Sous Chef | No |
| A random App Attest key ID that the app creates for this install (not your name, account or Apple's device identifiers), sent with each Sous Chef request | Security and abuse prevention: proving each request comes from a real copy of Sazón Vital and limiting how many requests one install can make | Our AI proxy (Cloudflare Workers), which keeps it with request counts | With every Sous Chef request | No |
| If you own a recipe pack, the App Store's signed record of that purchase (which pack, when, the price and store country, and Apple's purchase IDs) | To confirm you own a pack, so our AI proxy can apply the limits for pack owners; the proxy checks the record with Apple's certificates | Our AI proxy (Cloudflare Workers), which keeps only a hash of it with the pack and its expiry | Only if you own a recipe pack, with each Sous Chef request | No |
We don’t sell your information, and it isn’t used for advertising.
Services we use
These outside services receive data from Sazón Vital to make it work. Each handles that data under its own privacy policy.
- Marketgence AI proxy (Cloudflare Workers)
- Our own AI proxy, run by Marketgence on Cloudflare Workers. It checks the Apple App Attest signature on each request, limits how many requests each install can make, and forwards the request to the Vercel AI Gateway under our key. It keeps no copy of what you send or get back. What it receives: The messages, kitchen details, marked health conditions, recipe requests and pantry photos in each AI request, this install's random App Attest key ID and signature, for pack owners the App Store's signed purchase record, and normal connection data such as your IP address. No account. When you use the Sous Chef, create a recipe or scan a photo. For each install it keeps the App Attest key ID, public key, Apple's attestation receipt, first and last use, and request counts. For pack owners it also keeps a hash of the purchase with its pack and expiry, and checks it again after 24 hours. All of it is deleted after 180 days without use. Privacy policy: cloudflare.com.
- Vercel AI Gateway
- Receives each request from our AI proxy and routes it to Google Gemini, or to OpenAI when Google doesn't answer. What it receives: The messages, kitchen details, marked health conditions, recipe requests and pantry photos in each AI request, sent by our proxy under our key. It doesn't receive the App Attest key ID, the signature or your purchase. When you use the Sous Chef, create a recipe or scan a photo. Not set by the app. Vercel may keep request logs or metadata under its own policy. Privacy policy: vercel.com.
- Google (Gemini 2.5 Flash and Gemini 2.5 Flash Image)
- Writes Sous Chef replies and recipes, checks recipes, lists the ingredients in pantry photos and draws recipe pictures. What it receives: Chat messages, kitchen details, marked health conditions, recipe requests and pantry photos, as forwarded by the Vercel AI Gateway; for a picture, the recipe's title and main ingredients. When you use the Sous Chef, create a recipe or scan a photo. Under Google's own policy. Privacy policy: policies.google.com.
- OpenAI (GPT-4o mini)
- Stands in for Google on Sous Chef replies, recipes, recipe checks and pantry photos when Google doesn't answer. What it receives: The same content Google would get, as forwarded by the Vercel AI Gateway. Only when Google doesn't answer. Under OpenAI's own policy. Privacy policy: openai.com.
- Apple (speech recognition)
- Turns what you say to the Sous Chef into text, in Spanish. It runs on your iPhone when your iPhone supports it; otherwise Apple's speech service transcribes the clip. What it receives: Your voice clip, only when your iPhone can't recognize speech on its own. Nothing about your voice goes to us or to the AI services. Replies are read aloud by your iPhone's own voice, which sends nothing. Only after you hold the microphone button in Chef. Under Apple's own policy. Privacy policy: apple.com.
Artificial intelligence
Sous Chef chat, recipe creation and safety checks, pantry photo recognition and recipe pictures. It uses Google (Gemini 2.5 Flash; Gemini 2.5 Flash Image for recipe pictures) and OpenAI (GPT-4o mini, only when Google doesn't answer) through our AI proxy (run by Marketgence on Cloudflare Workers) and the Vercel AI Gateway. When you use it, this is sent: Your latest chat messages, the health conditions you marked, excluded ingredients, pantry, shopping list, weekly plan, servings and tastes saved from your recipe feedback; recipe requests; pantry photos. The recipe's title and main ingredients go to the image model for its picture. No account. Each request also carries a random App Attest key ID for this install. The service generates the answer and may keep request records under its own policy. Don’t include anything you wouldn’t want processed this way.
AI-generated text can be wrong or incomplete; see the Terms of Use.
Permissions
Sazón Vital asks for these only when you use the feature that needs them. You can change your answer at any time in the Settings app.
| Permission | Why |
|---|---|
| Camera | To photograph your fridge or pantry so the Sous Chef can list the ingredients. |
| Microphone | To record what you say to the Sous Chef while you hold the microphone button. |
| Speech Recognition | To turn what you say to the Sous Chef into text with Apple's speech recognition. |
Tracking, ads and analytics
Sazón Vital doesn’t track you: it doesn’t link information about you with information from other companies’ apps, websites or data brokers, and it doesn’t use an advertising identifier.
Sazón Vital doesn’t show ads.
It has no analytics or crash-reporting services. If you’ve chosen to share analytics with app developers in your iPhone’s settings, Apple may share crash reports with us; Apple doesn’t include your identity.
Accounts
There are no accounts in Sazón Vital. You don’t sign in or give us your name or email address.
Purchases
Sazón Vital offers one-time purchases through Apple’s App Store. Apple processes the payment and knows what you bought; we don’t receive your name, email address or payment details. The app checks what you’ve bought on your device with Apple’s StoreKit. Apple’s Privacy Policy applies to the purchase.
Children
Sazón Vital isn’t directed at children under 13, and we don’t knowingly collect personal information from them. Made for adults, including older adults; not directed at children.
How long data is kept, and deleting it
Information on your device stays until you delete it. You can delete it in the app: Perfil ▸ “Tus datos” ▸ “Borrar todos mis datos de este teléfono” erases your conditions, pantry, recipes, plan, shopping list, Sous Chef chat, recipe pictures and recovery copies. It keeps only today's free recipe count and the App Attest key ID. Deleting Sazón Vital removes the information it keeps in its own storage on your device; copies in your backups remain until you delete those. If you've bought something, a random purchase identifier that the app keeps in the iOS Keychain can stay on the device after the app is deleted, so your purchases can be matched again; it doesn't identify you.
Marketgence AI proxy (Cloudflare Workers): For each install it keeps the App Attest key ID, public key, Apple's attestation receipt, first and last use, and request counts. For pack owners it also keeps a hash of the purchase with its pack and expiry, and checks it again after 24 hours. All of it is deleted after 180 days without use.
Vercel AI Gateway: Not set by the app. Vercel may keep request logs or metadata under its own policy.
Google (Gemini 2.5 Flash and Gemini 2.5 Flash Image): Under Google's own policy.
OpenAI (GPT-4o mini): Under OpenAI's own policy.
Apple (speech recognition): Under Apple's own policy.
Your rights
Depending on where you live (for example in the European Union, the United Kingdom or California), you may have the right to know what information we hold about you, to get a copy, to correct or delete it, and to object to how it’s used. Because Sazón Vital keeps your information on your device, you can see, change and delete it in the app. To make a request or a complaint, email support@marketgence.com. You can also contact your local data-protection authority.
Changes to this policy
If we change how Sazón Vital handles information, we’ll update this page and its effective date, and list the change below.
- : Sazón Vital no longer has accounts or a server of its own, and recipes the Sous Chef makes are no longer shared with other people. Your data stays on your phone, and “Tus datos” saves a copy to a file, brings it back or erases everything. AI requests go through our own AI proxy and the Vercel AI Gateway to Google Gemini, with OpenAI as a fallback. Voice uses Apple's speech recognition.
- : Terms: AI recipes are provided as is and aren't medical or nutrition advice; the app's recipes belong to Marketgence Technologies LLC with a personal licence for you; what you send stays yours; rules against offensive content.
- : First version on apps.marketgence.com, replacing an earlier policy hosted elsewhere that was wrong: purchases are checked on the device with Apple's StoreKit and no third-party purchase processor is used; the app does use the camera and microphone; and it sends chats, photos and health conditions to AI services.
