Privacy Policy

Effective Date: August 29, 2026
Last Updated: September 20, 2026

This Privacy Policy applies to mobile applications, websites, and related services published or operated by İsmail KURT (“Developer,” “we,” “us,” or “our”), unless a specific application provides a separate privacy policy.

This copy of the policy is published at jewelcheckapp.com for the iOS application Jewelry Identifier: JewelCheck and for this website. Where the policy refers to "the application" or "the Services", it covers JewelCheck and jewelcheckapp.com.

In this Privacy Policy, our mobile applications, websites, and related services are collectively referred to as the “Services.”

The features and data practices of each application may vary. Not every category of information or third-party service described below is used by every application. Data is collected only when required for the features available in the application you use.

By using our Services, you acknowledge the practices described in this Privacy Policy.

1. Information We May Collect

Depending on the application and the features you use, we may collect or process the following categories of information.

Information You Provide

You may choose to provide information such as:

  • Images, photographs, screenshots, documents, audio, video, text, prompts, notes, or other content submitted for processing
  • Information entered into forms or application features
  • Preferences, settings, and customization choices
  • Messages and information included in support requests
  • Feedback, ratings, or survey responses

Please avoid submitting sensitive or confidential information unless it is necessary to use a particular feature.

Photos, Camera, Microphone, and Files

Some applications may request access to your camera, photo library, microphone, or files when required for a feature you choose to use.

Access is requested through the permission system provided by your device. We do not access these resources without permission. Where supported, you may select individual items instead of granting access to your entire library.

Content selected or created by you may be processed on your device or transmitted to our servers and service providers to perform the requested feature.

AI-Processed Content

Some applications may provide artificial intelligence features.

When you use an AI-powered feature, the content you submit—such as images, text, prompts, documents, or related metadata—may be transmitted to our servers and to an AI service provider for processing and generation of a response.

The information sent depends on the feature you use. We use this information to provide the requested output, maintain security, prevent abuse, and improve service reliability.

Where required, the application will inform you before content is shared with an external AI service and request your permission.

You should not submit content containing personal, confidential, financial, medical, or otherwise sensitive information unless you are authorized to do so.

Purchase and Subscription Information

If an application offers purchases or subscriptions, payments are processed by the applicable app marketplace, such as Apple’s App Store or Google Play.

We do not directly receive or store your complete payment card information. We may receive and process information such as:

  • Product or subscription purchased
  • Subscription status
  • Purchase and renewal dates
  • Store transaction or receipt information
  • Country, currency, and storefront information
  • An anonymous or pseudonymous application user identifier

This information is used to verify purchases, restore purchases, provide premium features, prevent fraud, and manage subscriptions.

Device, Security, and Diagnostic Information

We and our service providers may automatically process limited technical information, including:

  • Device type and operating system version
  • Application version
  • Language, locale, and time zone
  • Internet Protocol address
  • General network and request information
  • Anonymous or pseudonymous identifiers
  • App or device attestation information
  • Crash reports, error logs, and performance information
  • Date and time of requests
  • Information about how a feature performed

This information is used for security, fraud prevention, troubleshooting, diagnostics, and maintaining the reliability of the Services.

Advertising and Analytics Information

Some applications may use analytics or advertising services. Where applicable, these services may process information about application interactions, advertising identifiers, device information, or advertising activity.

If tracking permission is required, the application will request permission through the platform’s tracking authorization system.

We do not use information for cross-app tracking or personalized advertising without the permission required by applicable law and platform rules.

Information Stored on Your Device

Some information may be stored locally on your device, including:

  • Application settings and preferences
  • Saved results or history
  • Downloaded or generated content
  • Cached files
  • Onboarding status
  • Locally stored images or documents

You may be able to delete this information through the application, by deleting individual items, clearing application data, or uninstalling the application.

Deleting an application does not necessarily delete information already processed by third-party providers or information that must be retained for legal, security, or transaction-record purposes.

2. How We Use Information

We may use information to:

  • Provide and operate application features
  • Process content and generate requested results
  • Personalize settings and user experience
  • Verify purchases and provide premium access
  • Restore subscriptions and purchases
  • Respond to support requests
  • Diagnose errors and improve reliability
  • Protect the Services against fraud, abuse, and unauthorized access
  • Enforce applicable terms and policies
  • Comply with legal obligations
  • Improve existing features and develop new ones

We do not use submitted user content for materially unrelated purposes without providing notice and obtaining consent where required.

3. How Information May Be Shared

We may share information only as necessary with service providers that help us operate the Services.

Depending on the application, these providers may include:

  • Apple App Store and StoreKit
  • Google Play and Google Play Billing
  • RevenueCat for purchase and subscription management
  • Google Firebase for application security, authentication, cloud services, analytics, diagnostics, or other application infrastructure
  • Cloud hosting and backend infrastructure providers
  • Artificial intelligence providers, which may include OpenAI, Anthropic, or Google
  • Crash reporting, analytics, customer support, or advertising providers
  • Email and communication service providers

Not every application uses every provider listed above.

These providers process information according to their own privacy policies and their agreements with us. We require service providers handling user data on our behalf to apply appropriate confidentiality, security, and data-protection measures.

Information may also be disclosed:

  • When required by law, regulation, court order, or lawful government request
  • To protect the rights, security, and safety of users, the Developer, or others
  • To investigate fraud, abuse, or security incidents
  • In connection with a business transfer, merger, acquisition, or sale of assets, subject to appropriate safeguards

We do not sell personal information for monetary compensation.

4. Third-Party Privacy Policies

Third-party services may maintain their own privacy policies. Depending on the application, relevant policies may include:

Additional providers may be identified within the applicable application, its App Store or Google Play listing, or an application-specific notice.

5. Data Retention

We retain information only for as long as reasonably necessary to:

  • Provide the requested Services
  • Maintain security and prevent fraud
  • Complete and verify transactions
  • Resolve disputes
  • Comply with legal obligations
  • Enforce our agreements

Retention periods may vary depending on the type of information, the application, and the service provider involved.

User-submitted content processed by a server or AI provider may be retained temporarily as required to complete the requested operation, maintain security, investigate errors, or comply with the provider’s applicable retention rules.

Purchase records may be retained for the duration of the subscription and for any additional period required for accounting, fraud prevention, dispute resolution, or legal compliance.

Diagnostic and security logs may be retained for a limited period appropriate to their purpose.

Locally stored information remains on your device until you delete it, clear the application’s data, or uninstall the application.

6. Data Deletion and User Choices

Depending on the application, you may be able to:

  • Delete saved content or history within the application
  • Revoke camera, photo, microphone, file, or tracking permissions through device settings
  • Disable optional analytics or personalized advertising
  • Cancel subscriptions through your App Store or Google Play account
  • Delete your account through the application, if the application supports user accounts
  • Request access to or deletion of eligible personal information by contacting us

To submit a privacy or deletion request, contact:

ismail.kurtf@icloud.com

Please include the name of the application and enough information for us to understand and verify your request. Do not send passwords, payment card details, or other unnecessary sensitive information.

We may need to retain certain information when required by law or when necessary for security, fraud prevention, transaction records, or dispute resolution.

Revoking permission may prevent features that depend on that permission from working.

7. Legal Bases for Processing

Where applicable law requires a legal basis, we process personal information based on one or more of the following:

  • Your consent
  • Performance of a contract or provision of a requested service
  • Our legitimate interests in operating, protecting, and improving the Services
  • Compliance with legal obligations
  • Protection of users, the Developer, or others against fraud, abuse, or security threats

You may withdraw consent at any time where processing is based on consent. Withdrawal does not affect processing that occurred before consent was withdrawn.

8. Your Privacy Rights

Depending on your location, you may have rights to:

  • Request access to your personal information
  • Request correction of inaccurate information
  • Request deletion of eligible information
  • Restrict or object to certain processing
  • Request data portability
  • Withdraw consent
  • Opt out of certain advertising, tracking, sale, or sharing activities
  • Submit a complaint to the relevant data-protection authority

These rights may be subject to legal limitations and verification requirements.

We will not discriminate against you for exercising applicable privacy rights.

9. Children’s Privacy

Unless specifically stated otherwise, our Services are not directed to children under the age of 13 or the minimum age required by applicable law.

We do not knowingly collect personal information from children without the consent required by law. If you believe a child has provided personal information without appropriate authorization, contact us at ismail.kurtf@icloud.com so that we can investigate and take appropriate action.

10. Security

We use reasonable administrative, technical, and organizational measures designed to protect information against unauthorized access, alteration, disclosure, loss, or misuse.

However, no method of electronic transmission or storage is completely secure. We cannot guarantee absolute security.

11. International Data Transfers

Our service providers may process information in countries other than the country where you live.

Where required, we use appropriate safeguards for international transfers and require service providers to protect information in accordance with applicable law.

12. Links to Other Services

Our Services may contain links to third-party websites, applications, or services.

We are not responsible for the content, security, or privacy practices of third parties. You should review the privacy policy of any third-party service before providing information to it.

13. Changes to This Privacy Policy

We may update this Privacy Policy when our Services, service providers, legal obligations, or data practices change.

The updated version will be published with a revised “Last Updated” date. When required, we will provide additional notice or request renewed consent.
