This notice describes how CrimeCheck NZ handles personal information. It applies to the crimecheck.nzwebsite. CrimeCheck NZ is operated as a personal, non-commercial project by John Gregoriadis (the “operator”) and is not affiliated with, endorsed by, or operated by NZ Police, Stats NZ, or any government agency.
What we collect
The crime statistics shown on this site are aggregated public data and contain no information about identifiable individuals. CrimeCheck only collects personal information if you choose to subscribe to neighbourhood email alerts. In that case we collect:
- Your email address
- The suburb you ask to be alerted about
- Timestamps for verification, subscription, and any unsubscribe action
We do not collect your name, address, phone number, or payment information. Visitors who do not subscribe are not personally identified by us.
Your choices
Providing an email address is voluntary. If you choose not to provide one, you simply will not receive alerts — the rest of the site is unaffected. The legal basis for processing is your express consent under Information Privacy Principle 12 of the Privacy Act 2020. You can withdraw consent at any time by clicking the unsubscribe link in any alert email, or by contacting us directly.
Why we collect it
Email and suburb are used solely to deliver the monthly alerts you signed up for and to confirm your subscription via a one-time magic link. Timestamps support security (link expiry) and operations (responding to unsubscribe requests).
How long we keep it
Active subscriptions are retained until you unsubscribe. Unsubscribed records are retained for up to 12 months for fraud and abuse prevention, then deleted. Verification tokens expire 30 minutes after issue and are cleared automatically.
Where it’s stored
- Subscription data is stored in PostgreSQL hosted on Railway in their US-East region.
- Transactional email delivery is performed by Resend in the United States. Resend processes your email address and the message body of each alert.
- Site hosting is provided by Vercel.
Storage and processing therefore occurs outside New Zealand. By subscribing you consent to this offshore disclosure under Information Privacy Principle 12 of the Privacy Act 2020. You can withdraw consent at any time by unsubscribing.
Cookies and tracking
We use Google Analytics 4 (GA4) to understand aggregate site usage (page views, button clicks, navigation). GA4 sets first-party _ga cookies that persist for up to 13 months and may be considered personal information. IP addresses are not logged by Google, and we do not enable Google Signals, Google Ads linking, remarketing, or advertising features. You can opt out of GA4 by installing the Google Analytics opt-out browser add-on or by enabling tracking protection in your browser.
Crime statistics — not personal information
The statistics on suburb pages are aggregates over Area Units (Statistics NZ neighbourhood-sized regions, ~2,000 across NZ). They contain no records of individual incidents, victims, or offenders. Any single bucket with a count below 6 is suppressed to protect against re-identification.
Security
Verification and unsubscribe tokens are stored as HMAC-SHA-256 hashes, never as plain text. All traffic to the site is HTTPS. Access to the database is restricted to the operator.
Your rights under the Privacy Act 2020
You may at any time:
- Unsubscribe via the link in any alert email — this stops future emails immediately.
- Request access to the personal information we hold about you.
- Request correction or deletion of that information. To request deletion of unsubscribed records before the 12-month retention period, email us using the contact below.
If you are not satisfied with how we have handled a request, you can complain to the Office of the Privacy Commissioner on 0800 803 909.
