Introduction
This Privacy Policy explains how Yukka, a mobile application by Mehmet Sancaktutan & Burak Taş, handles your information. We built Yukka to respect you: we don't sell your data, we don't show ads, and we don't track you across other companies' apps.
By using Yukka, you agree to the practices described here. If you do not agree, please discontinue use of the app.
Information We Collect
We collect only what the app needs to work well for you. This falls into two groups: information you provide, and information collected automatically.
Information You Provide
This is the information you enter or submit directly while using the app:
- No account required: Yukka has no sign-in. We never create or collect a user ID, name, email, or password — the app is fully anonymous.
- Scanned products & photos: When you scan, the product barcode goes to public product databases. The photo you capture (or choose from the photo picker) is sent to a third-party AI service for analysis and is also cached on your device; it is never stored on our servers. The resulting product analysis is written to an anonymous shared catalog with no link to you, and individual entries cannot be undone.
- Scan history & favorites: Your scan history and favorites are stored only on your device and are never uploaded or synced to a server.
- Notifications: Notifications are generated entirely on your device — there are no server-sent push notifications, and no device notification token is created or shared. Permission is requested only once, after you complete your first scan, and is off by default. They are re-engagement reminders and daily tips; you can turn them off in Profile → Notifications or in iOS Settings.
- Preferences: Your dietary and product preferences (such as allergens, diet, health goals, and skin type) stay only on your device. Suitability is calculated entirely on-device; these preferences are never included in an AI request and are never sent to any server.
- Subscription status: Purchases are handled by Apple, and we never receive your card details. A third-party subscription-analytics service receives subscription transaction events along with your device identifier (IDFV), IP address, install ID, device model, OS version, language, and time zone. It runs in observer mode — it does not process payments or show paywalls — and is tied only to its own anonymous profile.
- No tracking or ads: There are no advertising SDKs, no cross-app tracking, and no ad-identifier-based targeting. The only analytics in use is the subscription and revenue reporting described above. Device permissions requested: the camera, for scanning, and notifications, which are optional. Photo library access is never requested.
Automatically Collected Information
To keep the app secure and reliable, limited technical information — such as your subscription and entitlement status and basic device information necessary for the app to function — may be processed. We do not use advertising identifiers and we do not build advertising profiles.
How AI Processing Works
When you scan a product, its barcode is checked against public product databases, and the product photo or name is sent securely over an encrypted connection to a third-party AI analysis service to produce a health breakdown. The request carries no account or user identifier, and your content is not used to train third-party models. In the photo-scanning flow, the product name and brand may also be passed to the AI provider's server-side web search tool to retrieve up-to-date ingredient information; that search likewise carries no user identity.
Purchases and Subscriptions
All purchases and subscriptions are processed by Apple through the App Store, and Apple handles billing. We never receive or store your payment card details.
Analytics
Yukka does not use third-party advertising or cross-app tracking analytics. Any analysis we perform is limited to aggregate, privacy-respecting diagnostics used to keep the app stable and improve reliability. We do not sell analytics data.
Backend Services
Your data is handled with privacy in mind. Your history and preferences are stored on your device rather than in an online account. Where the app connects to online services, data travels over encrypted connections (HTTPS/TLS), and without a login there is no profile linking that activity to your identity.
Third-Party Services
We rely on a small number of trusted providers to operate the app. Each processes data only as needed to deliver its function:
- Secure cloud database & storage — Stores an anonymous, shared product catalog so that once any user scans a product, its analysis is cached for everyone — repeat scans return instantly. No user identity, account, or device ID is attached to these records..
- Third-party AI analysis service — Identifies a scanned product and analyzes its ingredients, nutrition, and health risks. The captured product photo (or product name/ingredient text) is sent for analysis. No user identity accompanies the request..
- Public product databases — Look up food and cosmetic product details by barcode. Only the scanned barcode (or a free-text search term when browsing categories) is sent; no user data is attached..
- Subscription & billing (Apple) — All purchases and subscriptions are processed by Apple through the App Store using StoreKit. Payments are charged to your Apple ID; we never receive or store your card details..
- Subscription analytics service — A third-party service receives subscription transaction events (product ID and transaction), along with a device identifier (IDFV), IP address, install ID and device metadata (model, OS version, language, time zone), for revenue and subscription reporting. It runs in observer mode — it does not process payments or show paywalls — and it is tied only to its own anonymous profile, never to an app account..
These providers may process data outside your country. We choose providers that maintain appropriate security and data-protection standards.
Data Retention
We keep as little as possible. Because there is no account, your history and preferences are stored only on your device and remain available for as long as you keep the app installed. Removing them in the app or uninstalling deletes them.
Data Deletion Requests
You can remove your data at any time: In Profile → Scan history, swipe a row left to delete it; remove favorites from Profile → My favorites. Delete the app to erase all on-device data. Anonymous analysis entries in the shared catalog cannot be removed individually, as they are not linked to you.. Because there is no account, your history and preferences live only on your device, so clearing them in the app or deleting the app removes them completely.
Deleting the app from your device does not cancel any active subscription. If you need help, contact us at support@aurelionlabs.digital and we will assist with your request.
Children's Privacy
Yukka is not directed to children under 13 (or the minimum age required in your region). We do not knowingly collect personal information from anyone under that age. If you believe a child has provided us data, contact us and we will delete it.
International Users
You can use the app from anywhere in the world. Because we work with international providers, your information may be processed in countries other than your own. Where applicable law (such as the GDPR or Turkey's KVKK) grants you rights to access, correct, export, or erase your data, we honor those rights — most can be exercised directly in the app, and the rest by contacting us.
Changes to This Policy
We may update this Privacy Policy from time to time. When we do, we will revise the date at the top of this page. Significant changes will be communicated within the app where appropriate.
