Account sign-in and deletion
Google and Apple sign-in, when configured, share a verified identity identifier and email address with regzcheck. You can link a provider to an existing account without changing its subscription or usage. Apple authorization tokens are encrypted on the server so authorization can be revoked when you delete your account. Delete your account from AI access or the native Account tab; active website subscriptions are canceled as part of deletion. Live account records are removed, while Stripe billing records and private backups may have separate retention. Contact regzcheck@gmail.com for help.
Visitor analytics
With your permission, Google Analytics measures visits and use of public pages using cookies and device/browser information. Optional analytics is off until you allow it. We exclude search query strings and do not install analytics on the admin or AI account pages. You can change your choice here at any time.
Privacy & advertising
Search requests are processed on this server. AI questions and supporting passages are sent to OpenAI. Accounts store your email, password hash, trial usage, subscription status, saved order references, page bookmarks, and optional bookmark notes. Stripe processes payments; card details are not stored on this server. One verified AI answer is free per account, followed by an optional $4.99 USD monthly subscription with 300 verified AI answers per billing month. Unused answers do not roll over. Failed or unsupported answers do not count. AI service limits and temporary outages may apply. Manage or cancel your subscription from AI access. Uploaded documents are public reference material: do not upload classified, controlled, private, or sensitive information. Public search and information pages include Google AdSense code. Google may collect device and browsing information and use cookies or similar technologies to provide, measure, and personalize advertising. We do not attach your AI questions, account credentials, or uploaded document contents to ad requests. See how Google uses information from partner sites.
