Privacy Policy

> effective 30 September 2026 · v3.6

Plain-English summary: SkuEstimator runs on your computer. Your models, prices, customers and estimates are stored locally and are never uploaded to us. We hold no copy of your work. Apart from a small licence check and anything you choose to send to the optional AI assistant, nothing leaves your machine. Details below. This policy sits alongside our Terms of Service.

1. What we collect

The personal information we hold is limited to what we need to sell you a licence and support you:

  • Your subscription — your email address, your Stripe customer reference and your subscription status and dates. Your billing name, address, ABN and invoices are held by Stripe (see Billing).
  • Your licence — a one-way hash of your licence key (not the key itself), the computers it is activated on and when each last checked in, and when the installer was downloaded (see section 3).
  • Abuse-prevention records — our licence server records the IP address of each request to it (and, for “lost key” requests, the email address entered) so it can limit repeated requests. These records are deleted after 2 days.
  • Earlier waitlist sign-ups — if you joined our former waitlist, your email, optional company name and your answer about component attributes. We use it only to contact you about SkuEstimator.
  • Messages you send us — if you email us or use the contact form (your name, email address, topic and message), we keep the correspondence so we can help you. Contact-form messages, including your IP address, are delivered to our inbox by Resend; the message itself is not stored on our website or licence server.

This website uses privacy-friendly, cookie-free visitor statistics (Cloudflare Web Analytics — see section 5). We do not track you across other websites, and the plugin contains no telemetry of any kind. Apart from the licence check described below (which tells us when each computer last checked in) and installer downloads, we cannot see whether you installed it, opened it, or what you did with it.

2. What the plugin stores — on your computer

Everything the plugin creates lives on your own machine. None of it is transmitted to us, and we have no ability to read it.

  • Inside your .skp file — document edits, processed flags and colour assignments. These follow the SketchUp® save cycle: close without saving and they are discarded.
  • In your Windows application-data folder — templates, suppliers, customers, pricing rules, your company profile, any supplier price files you attach, and your licence key (encrypted).
  • If you use the AI assistant — your AI API key (encrypted), conversation logs, notes the assistant saves for you, usage and cost records, and a history of any prices it filled in for you.
  • A local error log — kept on your machine to help diagnose problems. It is never sent anywhere automatically; if you want us to see it, you export it and send it yourself.

Because this data is local, it is your responsibility to back it up. The plugin includes a one-click backup tool for exactly this.

3. When data leaves your computer

The licence check. To confirm your licence, the extension sends our licence server (hosted by Cloudflare) your licence key and a pseudonymous device code; when you activate a computer it also sends that computer’s name. The device code is a one-way hash of your Windows machine ID and user name: it cannot be turned back into those details, but it stays the same for that computer. The computer name lets you see which machines use your 2 seats. We record when each computer last checked in. Like any internet request, the check also reveals your IP address; our licence server records it for abuse prevention (see section 1) and Cloudflare may keep it in its request logs. The licence is checked when you activate it, about a minute after SketchUp starts and every 6 hours while it is open; SkuEstimator works offline for up to 30 days between successful checks. Nothing about your models, estimates, prices or customers is ever sent.

The optional AI assistant.

When you issue an AI command, what you typed or said, the name of your model, any notes you have asked the assistant to remember, and the data it looks up to answer that request — component attributes, item codes, supplier names, price-file rows and the figures involved — are sent to the AI provider you chose (OpenAI or Anthropic) to be answered.

Nothing is sent unless you initiate it. The AI assistant is entirely optional, requires you to supply your own API key, and every other feature — estimating, documents, pricing, rules, orders — works without it.

Optional voice dictation, if you enable it, sends the audio you record to OpenAI’s transcription API. Same principle: your key, your choice, off by default.

4. Third parties

  • OpenAI or Anthropic — whichever you choose for the optional AI assistant, using your API key under your agreement with that provider. OpenAI is also used for optional voice dictation. We are not a party to those agreements and never see your keys, which are encrypted on your machine. See OpenAI’s privacy policy and Anthropic’s privacy policy.
  • Stripe — processes subscription payments. Your card details go directly to Stripe; we never see or store them. See Stripe’s privacy policy.
  • Cloudflare — hosts this website, our licence server and its database, and provides our website visitor statistics (Cloudflare Web Analytics).
  • Resend — delivers our transactional emails, such as your licence key, and contact-form messages to our inbox.

Overseas disclosure. Some of these providers store or process information outside Australia, mainly in the United States:

  • Stripe (payments and billing details), Cloudflare (website, website visitor statistics, licence server and its database, including IP addresses in request logs), Resend (licence-key and other transactional emails, and contact-form messages) and Google Fonts (your browser’s IP address when a page loads fonts) — all in the United States and other countries where they operate.
  • Anthropic and OpenAI (United States) — only if you enable the optional AI assistant or voice dictation, and only with your own keys. Both are off until you turn them on.

5. This website

Visitor statistics. We use Cloudflare Web Analytics to see how many people visit and which pages they read. It sets no cookies, stores nothing in your browser, does not fingerprint your device and does not follow you to other websites. When a page loads, a small script from Cloudflare records the page address, the page you came from, your browser and device type, your approximate country (worked out from your IP address) and page-load timings. We only ever see these as totals in our Cloudflare dashboard — never a profile of an individual visitor — and we do not combine them with your licence or billing details. You can block the script with any content blocker and the site works exactly the same. See Cloudflare’s privacy policy.

No tracking or advertising cookies, no advertising pixels, no session recording. Fonts are served from Google Fonts, which means your browser makes a request to Google when you load a page. Nothing else about your visit is recorded, except that the forms on this site (checkout, contact, account and lost-key) send their requests through our licence server, which keeps the abuse-prevention record described in section 1.

6. Billing

Subscriptions are processed by Stripe. Your card details go directly to Stripe; we never see or store them. Stripe holds your billing name, address, ABN if you give one, and your invoices. Our licence database keeps only your email address, your Stripe customer reference and your subscription status and dates. If a billing notification from Stripe fails to process, we keep a copy of it (which can include your billing name and address) for up to 90 days so we can fix the problem.

Retention. Our licence server deletes records automatically:

  • Your account (email, licence, computers and subscription status) — kept while you subscribe and for 12 months after your subscription ends, so you can come back with the same licence key; then deleted.
  • Computers you release — deleted 12 months after you release them.
  • Abuse-prevention records (IP addresses, lost-key emails) — 2 days.
  • Copies of failed billing notifications — 90 days.
  • Our licence event log (activations, downloads, billing changes) — 24 months.

Billing records (invoices) are kept by Stripe for 7 years, as Australian tax law requires. Contact-form messages, support emails and any former waitlist entries are kept only as long as we need them to respond to you. You can ask us to delete your records sooner at any time (see section 7).

Emails. We send only transactional emails: your licence key (with the date your trial ends). Receipts and failed-payment notices come from Stripe. No marketing emails.

7. Your rights

Under the Australian Privacy Act, and the GDPR where it applies, you may access, correct, export or delete the personal information we hold about you. In practice that means your subscription, licence, device and abuse-prevention records and any support correspondence — we hold nothing else. Billing records we must keep for tax purposes cannot be deleted before the 7-year period ends.

Email hello@skuestimator.com and we will respond within 7 business days and complete the request within 30 days. To remove your locally stored plugin data, delete the application-data folder; the plugin’s documentation tells you where it is.

Complaints. If you are unhappy with how we have handled your personal information, email us first and we will respond within 30 days. If you are still not satisfied, you can complain to the Office of the Australian Information Commissioner (OAIC) at oaic.gov.au.

8. Security

  • This site is served over HTTPS.
  • All connections the plugin makes verify the server certificate and are restricted to a fixed list of permitted hosts.
  • Our licence server stores only a one-way hash of your licence key, never the key itself; on your computer the key is stored encrypted.
  • Your AI API key is encrypted at rest on your machine using Windows’ own data-protection service, tied to your user account. It is never written in plain text and never leaves your computer except as authentication to the provider you configured.
  • Because your models and estimates never reach our infrastructure, there is no copy of your commercial data for us to lose.

9. Changes

If this policy changes materially, we will update it here and email subscribers at least 30 days before the change takes effect.
