Scope
This policy describes information handled by DPC Rapaport Price for the website and Diamond Price Checker app. Contact us through this website’s Contact Us form for privacy questions or requests.
Account and support information
We process your name, email, authentication information and information you choose to provide, such as phone, company, country, occupation and profile notes. We also process messages submitted to our support form. Passwords are hashed; access tokens are stored as hashes.
Calculations and technical information
We store calculation parameters, saved results, source dates and website trial usage. Technical information such as request timing and IP addresses may be processed for delivery, security and abuse prevention. Signing in again does not reset website usage.
Device contacts
The mobile app uploads contacts only after device permission is granted. The server can store names, first phone numbers and first email addresses within your account and deduplicates repeat uploads. The current API does not message those contacts or automatically share calculations with them. Revoking device permission prevents future access but does not erase earlier uploads; delete your account or contact us to request removal.
Purpose and browser storage
We use information to operate accounts and tools, preserve your saved results, answer support requests and protect the service. Authentication uses necessary session cookies; browser storage remembers language. Optional device permissions are separate from account access. Where applicable, processing relies on providing the requested service, legitimate operational interests, legal obligations or consent.
Providers, payments and notifications
Hosting and infrastructure providers process information needed to deliver the service. Apple processes app purchases under its own terms and privacy policy; we do not store full payment-card details. Where enabled in the app, a notification provider such as OneSignal may receive account email and device identifiers for account identification and notifications. Manage notification permission in device settings. We do not sell personal information or uploaded contacts. Information may be disclosed when legally required.
Retention and deletion
Account information and uploaded contacts are retained while needed for the account. Account deletion removes associated mobile account data, saved calculations, contacts and sessions from the active backend. Website customer records linked to that account are also removed. Support enquiries are handled separately; request their deletion through Contact Us. Restricted backups may retain earlier copies until replaced or deleted. Apple purchase history and information held independently by external providers follow their own rules.
Your choices and security
You may request access, correction or deletion through Contact Us and withdraw optional device permissions. Available legal rights depend on applicable law. We use HTTPS, restricted access and hashed credentials, but cannot guarantee absolute security. This service is not intended for children under 13; contact us if a child has supplied information.
Policy changes
We may update this policy as the service changes. The date above identifies the current version. Material changes will be communicated through the service where appropriate; any legally required new consent will be requested separately.
