Purelyz: Ingredient Scanner

Last updated: August 20, 2026

This Privacy Policy describes how Purelyz("we", "our", "us") collects, uses, and protects your information when you use the Purelyzmobile application (the "App"). By using the App, you agree to the practices described here.

1. Information We Collect

1.1 Information you provide

  • Label photos. The photo you take of an ingredient label is sent to our servers and to Google (Gemini), the AI service that reads it and writes your analysis. It is deleted once the analysis is complete. It is never used for advertising and never shared with anyone else.
  • Your preferences. The dietary restrictions and categories you choose during setup stay on your device. They are not sent to our servers and are not part of the analysis request.
  • Purchase confirmations. Apple confirms successful purchases so we can add your credits or unlock your subscription. We never receive your card details.

1.2 Information collected automatically

  • Anonymous user identifier. A unique identifier generated on first launch. No real name, email, or phone number is required to use the App.
  • Device identifier. A randomly generated UUID stored locally on your device, used so the same installation is recognized across sessions.
  • Device information. Device model, operating system version, and App version — used for debugging and compatibility.
  • Usage data. Feature usage, subscription status, and credit balance.
  • Diagnostics. Anonymous error and performance logs that keep the App working. They are not tied to your identity.

1.3 Information from Apple services

  • App Attest.A cryptographic key issued by Apple's App Attest service is used to verify requests come from a genuine, unmodified instance of the App. The key itself does not identify you.
  • DeviceCheck. A device-level token used to prevent abuse of one-time signup bonuses. Forwarded to Apple for verification and not stored on our servers.
  • Push notifications.If enabled, your device's push token is stored so we can notify you about activity in your account.

2. How We Use Your Information

We use collected information to:

  • Read the ingredient label you photograph and generate your analysis.
  • Manage your anonymous account, credits, and subscription.
  • Send a notice when your analysis is ready, if you allow notifications. You can turn them off at any time in iOS Settings.
  • Keep the App working through anonymous error and performance diagnostics.
  • Prevent fraud, abuse, and automated bot activity.
  • Comply with legal obligations.

3. Third-Party Services

The App relies on a small set of third-party providers to deliver its core features. These providers process data on our behalf and are bound by their own privacy policies and contractual obligations:

  • Google (Gemini). Processes your label photo to generate the analysis.
  • Apple. Handles all payments, credit packs and subscriptions, and provides App Attest, DeviceCheck, and push notifications (APNs).
  • RevenueCat. Validates those purchases. It receives your Apple purchase identifier, never your identity.

We do not sell your personal data to third parties, and we do not use it for advertising or cross-app tracking.

4. Data Retention

  • Account data is retained for as long as your account is active.
  • Uploaded content. Your label photo is sent over HTTPS to our servers and to Google (Gemini) for analysis, and is deleted once the analysis is complete. Your account is tied to your device — no email, no name, no social login. Every finished analysis is written to your device and stays readable without a connection, and remains there until you delete it or delete your account.
  • Account deletion. You can delete your account at any time from Settings → Delete Account in the App. Your account, your scan history, and your stored data are permanently removed.

5. Data Security

Biometric data is not collected.

We do not collect or process biometric data. A photo of a product label is not used to identify anyone, and your account is not attached to it. We use no advertising SDKs and no trackers.

We apply industry-standard security practices:

  • All communication with our servers is encrypted in transit (HTTPS / TLS).
  • Stored content is isolated per app and per account.
  • Authentication tokens are stored in your device's secure keychain.
  • App Attest cryptographically verifies that requests originate from a legitimate installation of the App.

No method of internet transmission or electronic storage is fully secure; we apply commercially reasonable measures to protect your data and are continuously improving them.

6. Your Rights

Depending on your jurisdiction (including the European Union under GDPR and Turkey under KVKK), you may have the right to:

  • Access the personal data we hold about you.
  • Request correction or deletion of your data.
  • Withdraw consent for data processing.
  • Object to certain types of processing.
  • Request data portability.

To exercise these rights, contact apps@batuhanarda.com. We will respond within 30 days.

7. Children's Privacy

This App is not intended for anyone under 13. We do not knowingly collect personal information from anyone under that age. If you believe someone under 13 has provided us information, please contact us so we can remove it.

8. Changes to This Policy

We may update this Privacy Policy from time to time. Material changes will be communicated through the App. The "Last updated" date above indicates the most recent revision.
